The patient would have 50mg of the drug remaining in their body after 24 hours.
A patient receives 200 mg of a medication that has a half-life of 12 hours. How many mg of the drug would remain in the patient's body after 24 hours?
The initial dosage of the drug given to the patient is 200mg. The half-life of the medication is 12 hours. In other words, half of the drug is metabolized and removed from the patient's system after 12 hours.The remaining 100mg of the drug will remain in the patient's body after 12 hours.
After another 12 hours, the half-life will occur again, meaning that half of the remaining drug in the body will be metabolized and removed. Therefore, after 24 hours (or 2 half-lives), the amount of the drug remaining in the patient's system can be calculated as follows:Initial dosage of the drug = 200mg
Half-life of the drug = 12 hours
After 12 hours, the amount of drug remaining in the body = 100mg (half of the initial dose)
After 24 hours, the amount of drug remaining in the body = 50mg (half of the amount remaining after 12 hours)
Therefore, the patient would have 50mg of the drug remaining in their body after 24 hours.

1) The article is attached to this submission. Li, H., Chen, S., Yang, X., Wang, Y., Lin, Q., Xu, C., ... & Zhou, Q. (2018). Effect of multidisciplinary follow-up on blood pressure control, self-care behaviour and quality of life in hypertensive patients in China. Journal of clinical nursing, 27(1-2), e70-e80. doi: 10.1111/jocn.13948.
2) The design used in this research study is quasi-experimental design. In a quasi-experimental design, groups are not randomized, which means they are not randomly assigned to treatment or control groups, and the experimenter has little control over variables. Li et al. (2018) states that they chose the quasi-experimental design because they did not randomize the study participants into the intervention or control groups, but rather used patients who were already being treated at the same hospital. They were divided into an intervention group that received multidisciplinary follow-up and a control group that received routine care.
3) The research study found that the multidisciplinary follow-up intervention was effective in controlling blood pressure, improving self-care behavior, and enhancing the quality of life of hypertensive patients in China. Patients who received the intervention had significantly lower systolic and diastolic blood pressure levels, better self-care behavior, and higher quality of life scores than those who received routine care. These findings have important implications for clinical practice because the multidisciplinary follow-up intervention is a cost-effective and feasible strategy that can be used to improve the quality of care and outcomes for hypertensive patients. Future nursing research can build on this study by examining the effectiveness of similar interventions in other populations and settings and identifying ways to further improve the intervention.

Order: kanamycin 15 mg/kg per day IV in 2 equally divided doses. How many mg will you administer to a patient who weighs 70 kg? 12 Find the BSA of a patient who weighs 80 kg and is 166 cm tall. 13 A patient weighing 100 lb must receive 15 mg/kg PO of a drug. How many 700 mg tablets will you administer? 350 mm
Kanamycin is an antibiotic used to treat severe bacterial infections and tuberculosis. This drug is not the drug of choice. This medication can be taken by mouth, injected into a vein, or injected into a muscle. Kanamycin belongs to the aminoglycoside group which works by inhibiting the production of proteins needed by bacteria to live.
To answer the following questions, you need to use the appropriate mathematical formulas.
Order kanamycin 15 mg/kg per day IV in 2 equally divided doses. How many mg will you administer to a patient who weighs 70 kg?
Answer To calculate the dose of kanamycin to give a patient, you need to multiply the patient's weight by the dose per kilogram. The dose per kilogram is 15 mg/kg per day. So, the total dose given is:
15 mg/kg x 70 kg = 1050 mg per day
Because the dose is divided into two administrations, the dose per administration is:
1050 mg / 2 = 525 mgSo you'd give 525 mg of kanamycin each time.
12 Find the BSA of a patient who weighs 80 kg and is 166 cm tall.
Answer: To calculate the patient's body surface area (BSA), you can use the Du Bois formula. This formula is:
BSA = 0.007184 x (body weight in kg)^0.425 x (height in cm)^0.725
So, the patient's BSA is:
BSA = 0.007184 x (80 kg)^0.425 x (166 cm)^0.725
BSA = 1.86 m^2
13 A patient weighing 100 lb must receive 15 mg/kg PO of a drug. How many 700 mg tablets will you administer?
Answer: To calculate the number of tablets given to a patient, you need to take a few steps:
1) Convert the patient's weight from pounds to kilograms. One pound is equal to 0.4536 kilograms. So, the patient's weight in kilograms is:
100 lb x 0.4536 kg/lb = 45.36 kg
2) Calculate the total dose required by the patient by multiplying the patient's body weight by the dose per kilogram. The dose per kilogram is 15 mg/kg. So, the total dose required is:
15 mg/kg x 45.36 kg = 680.4 mg3) Divide the total dose by the tablet strength to get the number of tablets administered. The strength of the tablets is 700 mg. So, the number of tablets given is:
680.4 mg / 700 mg = 0.97Since it is not possible to give a portion of the tablet, you should round the result up or down according to your doctor's or pharmacist's instructions. For example, if you round up the number of tablets given is:

The method of administration depends on the route of medication which can range from oral, subcutaneous, topical, intramuscular or intravenous. When administering medication, a nurse should be careful of the medication approach in order to avoid errors that might be detrimental to the patient. In administering medication, it is crucial to consider the drug reference information for the medication being administered. In this context, an order of administration of Medication as 60 mg IV push is received by the nurse, and the drug reference information about the rate of administration is 25 g or any action that takes over at least 30 seconds. The rate of administration is calculated as follows:
60 mg = 0.06 g and 25 g is to administered in 1 second.
Then, 0.06 g can be administered in = (0.06/25) second = 0.0024 second. This is the rate of administration in grams per second. Since we need to convert this value to milliliters per second, we need to use the conversion factor of 1 g = 1 mL. Therefore, the rate of administration is = 0.0024 x 1 mL/sec = 2.4 mL/sec. Hence, the rate of administration for the ordered medication is 2.4 mL/sec. This also means that the nurse should administer the medication over at least 30 seconds to avoid any potential side effects or adverse reactions. Furthermore, the patient should be closely monitored by the nurse during and post administration to ensure that they are not enduring any adverse reactions or side effects.

What is coccidioidomycosis?
A. a respiratory infection caused by gram positive cocci
B. an occupational interstitial lung disease
C. a disease of the upper motor neurons
D.• a fungal infection endemic to the arid southwestern US
Coccidioidomycosis is a fungal infection endemic to the arid southwestern United States.
Coccidioidomycosis, also known as Valley fever or San Joaquin Valley fever, is caused by the fungus Coccidioides. It primarily affects individuals living or traveling in regions with a dry climate, such as parts of California, Arizona, New Mexico, and Texas. The fungus is present in the soil, and when disturbed, releases spores into the air, which can be inhaled by humans.
Once inhaled, the Coccidioides spores can cause respiratory symptoms ranging from mild flu-like symptoms to severe pneumonia. The infection can also spread beyond the lungs to other parts of the body, such as the bones, skin, and central nervous system, leading to more severe complications.
Common symptoms of coccidioidomycosis include fever, cough, chest pain, fatigue, and joint pain. However, some individuals may have no symptoms or experience only mild symptoms. In severe cases, the infection can be life-threatening, especially for individuals with weakened immune systems.
Diagnosis of coccidioidomycosis is typically made through a combination of clinical evaluation, imaging tests, and laboratory tests, including blood tests and fungal cultures. Antifungal medications are used for the treatment of symptomatic or severe cases, while mild or asymptomatic cases may not require specific treatment and resolve on their own.
Prevention involves avoiding exposure to dust in endemic areas, using respiratory protection in high-risk environments, and being aware of the symptoms to seek early medical attention if needed.

13. Stroke volume at maximum VO2: 100 ml/beat
14. At maximum VO2, systolic systemic arterial pressure increases, while diastolic systemic arterial pressure remains relatively unchanged. Pulse pressure also increases.
15. Pulmonary blood flow increases approximately fivefold at maximum VO2.
16. At maximum VO2, the skeletal muscles receive the largest percentage of cardiac output.
17. Cerebral blood flow remains relatively constant during exercise due to autoregulation.
Explanation:
1. The approximate total blood volume can be calculated using the formula: Total blood volume = Plasma volume / (1 - Hematocrit). In this case, the plasma volume is given as 3200 ml and the hematocrit is given as 45%. So, the total blood volume is approximately 6400 ml.
2. Cardiac output at rest is calculated using the formula: Cardiac output = Stroke volume x Heart rate. Given that the stroke volume at rest is 80 ml/beat and the heart rate is 50 beats/min, the cardiac output at rest is 4.0 L/min.
3. Cardiac index at rest is calculated by dividing the cardiac output at rest by the body surface area. Given that the cardiac output at rest is 4.0 L/min and the body surface area is 1.6 m2, the cardiac index at rest is 2.5 L/min/m2.
4. Stroke volume at rest can be calculated using the formula: Stroke volume = Cardiac output / Heart rate. Given that the cardiac output at rest is 4.0 L/min and the heart rate is 50 beats/min, the stroke volume at rest is 80 ml/beat.
5. Stroke index at rest is calculated by dividing the stroke volume at rest by the body surface area. Given that the stroke volume at rest is 80 ml/beat and the body surface area is 1.6 m2, the stroke index at rest is 50 ml/beat/m2.
6. Pulmonary vascular resistance at rest can be calculated using the formula: Pulmonary vascular resistance = (Mean pulmonary artery pressure - Pulmonary arterial wedge pressure) / Cardiac output. Given that the mean pulmonary artery pressure at rest is 15 mmHg, the pulmonary arterial wedge pressure is 5 mmHg, and the cardiac output at rest is 4.0 L/min, the pulmonary vascular resistance at rest is 0.5 mmHg/L/min.
7. Systemic vascular resistance at rest can be calculated using the formula: Systemic vascular resistance = (Mean aortic pressure - Central venous pressure) / Cardiac output. Given that the mean aortic pressure at rest is 92 mmHg, the central venous pressure is 2 mmHg, and the cardiac output at rest is 4.0 L/min, the systemic vascular resistance at rest is 1,150 dynes-sec/cm5.
8. Maximum VO2 represents the maximum rate of oxygen consumption during exercise. In this case, it is given as 5.0 L/min.
9. The pulmonary vascular resistance at maximum VO2 is given as 1.0 mmHg/L/min.
10. The systemic vascular resistance at maximum VO2 is given as 230 dynes-sec/cm5.
11. Two mechanisms responsible for the alteration in pulmonary vascular resistance at maximum VO2 are hypoxic vasoconstriction and increased recruitment of pulmonary capillaries.
12. The alteration in systemic vascular resistance at maximum VO2 is primarily due to vasodilation of the systemic arterioles.
13. Stroke volume at maximum VO2 can be calculated using the formula: Stroke volume = Cardiac output / Heart rate. Given that the cardiac output at maximum VO2 is 5.0 L/min and the heart rate is 200 beats/min, the stroke volume at maximum VO2 is 100 ml/beat.
14. At maximum VO2, systolic systemic arterial pressure increases, while diastolic systemic arterial pressure remains relatively unchanged. Pulse pressure, the difference between systolic and diastolic pressures, increases.
15. Pulmonary blood flow increases approximately fivefold at maximum VO2 compared to rest.
16. At maximum VO2, the skeletal muscles receive the largest percentage of cardiac output.
17. Cerebral blood flow remains relatively constant during exercise due to autoregulation.

A. BNP
B. amylase
C. troponin levels
D• ALT
Option A. BNP (B-type natriuretic peptide) is the lab test most likely to indicate worsening heart failure in a patient with a history of heart failure.
A. BNP (B-type natriuretic peptide) is the lab test probably going to show demolishing cardiovascular breakdown in a patient with a background marked by cardiovascular breakdown. BNP is a chemical emitted by the heart in light of expanded tension and extending of the cardiovascular chambers. In cardiovascular breakdown, the heart can't siphon actually, prompting expanded tension and extending. Raised degrees of BNP in the blood are related with cardiovascular breakdown and can show deteriorating of the condition.
Amylase is a catalyst used to analyze pancreatic problems and isn't well defined for cardiovascular breakdown. Troponin levels are utilized to analyze heart muscle harm, ordinarily found in a cardiovascular failure. ALT (alanine aminotransferase) is a liver chemical used to evaluate liver capability and isn't straightforwardly connected with cardiovascular breakdown.

doing self care? Is self care important? How can you help a patient
ad
Coping mechanisms are a range of strategies that people use to cope with difficult life situations. Coping mechanisms can be adaptive or maladaptive. People can develop maladaptive coping mechanisms to help them deal with stress. For example, someone who uses alcohol or drugs to cope with stress is using a maladaptive coping mechanism.
In my experience, whenever I encounter stress or anxiety, I try to cope by taking a break from whatever it is that's causing the stress. I find it helpful to take a walk outside or listen to some calming music. I also find it helpful to talk to someone about what's going on and how I'm feeling.
Self-care is important because it helps people maintain their physical, mental, and emotional health. It's important to prioritize self-care in order to maintain good mental health, which in turn helps to maintain good physical health. Self-care can include things like exercise, meditation, spending time with friends and family, and engaging in hobbies and other activities that bring you joy.
To help a patient with self-care, you can start by encouraging them to make time for themselves and prioritize self-care. You can also provide them with resources and information about self-care, such as exercise programs, support groups, and mindfulness techniques. You can also encourage them to seek professional help if they are struggling with mental health issues.

You are the nurse manager on an ICU unit. The unit was exceptionally busy as you had a call in from a nurse and your CNA was pulled to another unit. Nurse Bonnie has 3 patients that day due to the call in. She was about to deliver medications when she received a call from a physician that needed to change orders on a very critical patient. Bonnie looked for another nurse to take the order, but there were none available. Everyone was very busy. So she left the PYXIS and went to answer the phone. She went back to Patient A’s room and administered the medication.
About an hour later, Nurse Bonnie comes to you and tells you she gave the medication for Patient B to Patient A. She had checked on the patient and there were no adverse reactions.
You report this incident to quality and call the patient A’s physician to report the error. Since there were no adverse reactions, the doctor said to continue to report this to Quality.
The Quality and the Legal department call you to do an RCA (Root Cause Analysis) on the situation. They told you to do the investigation on the incident.
During your investigation of the incident, you find out the nurse did not have the order sheet with her when she went to the PYXUS. After the phone call, she went into the patient’s room and gave the medication. After the phone call, she went into the patient’s room and gave the medication. When you talked to the nurse, she admitted she inadvertently put Patient B’s medication in her pocket and answered the phone call. She then went to Patient A’s room and administered the medication.
What patient safety goal(s) were violated?
What would you report in the RCA as the cause?
How would you prevent this happening the next time?
What actions are taken against the nurse?
In this incident, Nurse Bonnie inadvertently administered the medication meant for Patient B to Patient A. The patient did not experience any adverse reactions. The patient safety goal violated in this case is medication safety. The root cause analysis (RCA) investigation reveals that the nurse did not have the order sheet with her and mistakenly carried Patient B's medication.
To prevent such incidents in the future, improvements in communication, documentation, and medication verification processes should be implemented. Regarding actions against the nurse, it would depend on the organization's policies and protocols.
The patient safety goal violated in this case is medication safety. Administering the wrong medication to a patient is a serious error that can have severe consequences. The root cause analysis (RCA) would identify the cause of the incident as the nurse's failure to have the order sheet with her and inadvertently carrying Patient B's medication.
To prevent this from happening again, several measures can be implemented. First, ensuring that nurses have all necessary information, such as order sheets, before accessing medication administration systems like PYXIS. Adequate communication channels should be established to enable nurses to seek support or assistance when they are unable to leave their assigned tasks. Improved documentation processes, such as using barcode scanning or electronic medication administration records (eMARs), can help prevent medication errors. Regular training and education on medication safety and error prevention should also be provided to the nursing staff.
The actions taken against the nurse would depend on the organization's policies and protocols. Typically, a medication error of this nature would trigger an incident report, which would be reviewed by the quality and legal departments. Depending on the severity of the error and the nurse's previous record, corrective actions could range from additional training and counseling to disciplinary measures.
To ensure patient safety and prevent similar incidents in the future, a comprehensive approach that addresses communication, documentation, and medication verification processes should be implemented, while providing appropriate support and education to healthcare professionals.

What effect do cultural beliefs and values have on healthcare
decision-making?
Cultural beliefs and values can significantly impact healthcare decision-making as patients from different cultures may have varying perceptions of health, illness, and treatment.
Cultural beliefs and values influence how patients perceive health and wellness, how they view healthcare providers, and what interventions they may accept or reject. Healthcare providers must be sensitive to cultural differences and take these into account when making decisions and providing care.
Cultural factors can impact healthcare decisions in several ways. For example, a patient's belief system may influence their preferences regarding treatment modalities, such as alternative or complementary medicine. In addition, cultural norms may affect how patients communicate symptoms and health concerns, how they make treatment decisions, and how they cope with illness.
It is also important to recognize that cultural beliefs can vary among individuals within the same cultural group and that stereotyping based on cultural background can be harmful. Healthcare providers should strive to provide culturally sensitive and competent care, which includes acknowledging and respecting diverse cultural beliefs and values.

A patient on your unit is found to have pulmonary tuberculosis (TB). What is the most appropriate precaution for the staff to take to prevent transmission of TB? 0 A Standard and contact precautions
B. Standard and airborne precautions O C. Standard precautions only O D. Standard and droplet precautions
B. Standard and airborne precautions.
It is crucial to adhere to the appropriate precautions to protect healthcare workers and prevent the spread of tuberculosis within the healthcare setting.
The most appropriate precaution for the staff to take to prevent transmission of pulmonary tuberculosis (TB) is Standard and airborne precautions. Tuberculosis is primarily spread through the air when an infected individual coughs, sneezes, or talks, releasing infectious droplets containing Mycobacterium tuberculosis (the bacteria that causes TB) into the air.
Standard precautions are the basic infection prevention practices that should be followed in all healthcare settings for all patients, regardless of their diagnosis. These precautions include hand hygiene, the use of personal protective equipment (e.g., gloves, masks, gowns), safe injection practices, and proper handling and disposal of contaminated materials.
In the case of tuberculosis, airborne precautions should be added to standard precautions because the infectious particles can remain suspended in the air for an extended period. Airborne precautions involve the use of specialized respiratory protection, such as N95 respirators or similar high-filtration masks, to protect healthcare workers from inhaling the infectious droplets. Additionally, patients with TB should be placed in a negative pressure isolation room, which helps prevent the spread of airborne particles to other areas of the healthcare facility.
Droplet precautions (option D) are not sufficient for preventing the transmission of TB because the infectious particles are smaller and can remain suspended in the air for longer distances. Droplet precautions are primarily used for diseases transmitted through larger respiratory droplets that travel short distances, typically within approximately 3 feet.

The parent states that the child will not chew the tablet but will take oral liquids. Erythromycin is also available as 400 mg/5 mL. After obtaining the physician's
permission for the change, how many milliliters should be dispensed?
How many milliliters would be needed per dose?
The amount of oral liquid erythromycin to be dispensed depends on the prescribed dosage. Without the dosage information, the specific milliliter amount cannot be determined.
When converting from a tablet formulation (e.g., 400 mg) to an oral liquid formulation (e.g., 400 mg/5 mL), the prescribed dosage must be provided by the physician. The dosage will determine the amount of liquid to be dispensed. For example, if the prescribed dosage is 200 mg, then half of the tablet's strength should be dispensed, resulting in a specific amount in milliliters.
Furthermore, the milliliters needed per dose will depend on the prescribed dosage. The physician will specify the desired dosage, usually in milligrams (mg), and the pharmacist will calculate the corresponding volume of oral liquid needed for each dose. This calculation is based on the concentration of the oral liquid formulation, such as 400 mg/5 mL.
To determine the exact amount in milliliters for dispensing and per dose, the physician's prescribed dosage is essential. Only with the specific dosage information can the pharmacist accurately calculate the appropriate volume of oral liquid to dispense and the milliliters required per dose.
