1. Which drug undergoes extensive first-pass hepatic metabolism?
- A. Heparin
- B. Insulin
- C. Propranolol
- D. Nitroglycerin
Correct answer: C
Rationale: Propranolol undergoes extensive first-pass hepatic metabolism in the liver. When administered orally, propranolol is extensively metabolized by the liver before reaching systemic circulation, leading to reduced bioavailability. This process is known as first-pass hepatic metabolism, which significantly affects the drug's effectiveness and necessitates higher oral doses compared to other routes of administration. Heparin (Choice A) is not metabolized by the liver but excreted unchanged by the kidneys. Insulin (Choice B) is a peptide hormone that is not subject to significant first-pass metabolism. Nitroglycerin (Choice D) is primarily metabolized in the blood and tissues, bypassing significant first-pass metabolism in the liver.
2. When starting therapy with raloxifene, a client should monitor for which of the following adverse effects?
- A. Leg cramps
- B. Hot flashes
- C. Urinary frequency
- D. Hair loss
Correct answer: B
Rationale: The correct answer is B: Hot flashes. When initiating therapy with raloxifene, clients should be advised to monitor for hot flashes as they are a common adverse effect associated with this medication. Hot flashes are a well-known side effect of raloxifene due to its action on estrogen receptors. Leg cramps (Choice A), urinary frequency (Choice C), and hair loss (Choice D) are not typically associated with raloxifene therapy. Therefore, monitoring for hot flashes is crucial to manage and address this common side effect appropriately.
3. A client has a new prescription for Prednisone. Which of the following instructions should be included?
- A. Increase your intake of vitamin D.
- B. Take this medication on an empty stomach.
- C. Avoid drinking grapefruit juice.
- D. Take this medication every other day.
Correct answer: A
Rationale: When a client is prescribed Prednisone, it is important to increase the intake of vitamin D to help mitigate the risk of bone loss associated with the medication. Vitamin D aids in calcium absorption, supporting bone health in individuals taking Prednisone.
4. What is the correct medical term used to describe impaired blood flow in the coronary arteries?
- A. Myocardial infarction
- B. Angina pectoris
- C. Cerebrovascular accident
- D. Coronary heart disease
Correct answer: D
Rationale: The correct medical term for impaired blood flow in the coronary arteries is Coronary heart disease. This condition is characterized by a narrowing or blockage of the coronary arteries, leading to reduced blood flow to the heart muscle. Myocardial infarction (choice A) refers to a heart attack, which occurs when blood flow to a part of the heart is blocked. Angina pectoris (choice B) is chest pain or discomfort that occurs when the heart muscle doesn't receive enough oxygen-rich blood. Cerebrovascular accident (choice C) is the medical term for a stroke, which occurs when blood flow to a part of the brain is interrupted.
5. A client has a prescription for Desmopressin for the treatment of Diabetes Insipidus. Which of the following instructions should the nurse include in the teaching?
- A. Decrease fluid intake at the start of treatment.
- B. Monitor for nocturia.
- C. Report a weight loss of 0.5 kg (1.1 lb) per week.
- D. Expect permanent polyuria with this medication.
Correct answer: A
Rationale: Desmopressin is a medication used to reduce diuresis in clients with diabetes insipidus. To prevent water intoxication, clients should be advised to decrease fluid intake at the beginning of treatment. This instruction helps to balance fluid levels in the body and prevent potential complications associated with excessive fluid intake while on Desmopressin therapy. Monitoring for signs of fluid retention, such as weight gain, and adjusting fluid intake accordingly are essential components of client education when initiating treatment with Desmopressin.
