1. Which of the following is a potassium-sparing diuretic?
- A. Furosemide
- B. Spironolactone
- C. Hydrochlorothiazide
- D. Bumetanide
Correct answer: B
Rationale: Spironolactone is classified as a potassium-sparing diuretic. It works by antagonizing the aldosterone receptor, leading to potassium retention and sodium excretion. This mechanism makes it a suitable choice for conditions where potassium retention is desired, such as in patients with heart failure or liver cirrhosis. Choices A, C, and D are not potassium-sparing diuretics. Furosemide, hydrochlorothiazide, and bumetanide are loop diuretics and thiazide diuretics, respectively, which promote the excretion of potassium.
2. A healthcare professional is preparing to administer Enoxaparin to a client. Which of the following actions should the healthcare professional take?
- A. Administer the medication orally.
- B. Massage the injection site after administration.
- C. Insert the needle at a 45- to 90-degree angle.
- D. Aspirate before injecting the medication.
Correct answer: C
Rationale: Enoxaparin should be administered subcutaneously at a 45- to 90-degree angle. This angle ensures proper delivery of the medication. Massaging the injection site should be avoided to prevent bruising and possible tissue damage. Aspiration is not required for subcutaneous injections like Enoxaparin. Therefore, the correct action for administering Enoxaparin is to insert the needle at a 45- to 90-degree angle.
3. A client has a new prescription for Pancrelipase for chronic pancreatitis. Which of the following instructions should be included by the nurse?
- A. Take the medication with meals and snacks.
- B. Chew the tablet thoroughly before swallowing.
- C. Take the medication 1 hour before meals.
- D. Expect the stool to be yellow.
Correct answer: A
Rationale: The correct instruction for taking Pancrelipase is to take it with meals and snacks to aid in the digestion of fats, proteins, and carbohydrates. This helps optimize the effectiveness of the medication in managing chronic pancreatitis. Choice B is incorrect because Pancrelipase should not be chewed but swallowed whole. Choice C is incorrect as the medication should be taken with meals. Choice D is incorrect because while Pancrelipase can cause stool changes, yellow stool is not an expected outcome.
4. How do ACE inhibitors work?
- A. Block the vasoconstrictor and aldosterone effects of angiotensin II at the receptor site
- B. Block stimulation of beta 1 and beta 2 at the receptor sites
- C. Block the conversion of angiotensin I to the vasoconstrictor angiotensin II
- D. None of the above
Correct answer: C
Rationale: ACE inhibitors work by inhibiting the conversion of angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, and by blocking its production, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload of the heart. Choice A is incorrect because it describes the mechanism of action of angiotensin receptor blockers (ARBs), not ACE inhibitors. Choice B is incorrect as it describes beta-blockers, not ACE inhibitors. Choice D is incorrect as ACE inhibitors do have a specific mechanism of action.
5. A client is receiving epoetin alfa to treat anemia. Which of the following findings should the nurse monitor?
- A. Leukocytosis
- B. Hypertension
- C. Hyperkalemia
- D. Fever
Correct answer: B
Rationale: The nurse should monitor the client for hypertension when receiving epoetin alfa. Epoetin alfa stimulates red blood cell production, which can lead to increased blood pressure. Monitoring blood pressure is crucial to detect and manage hypertension promptly. Leukocytosis refers to an increased white blood cell count and is not directly related to epoetin alfa treatment. Hyperkalemia is an elevated potassium level, which is not a common adverse effect of epoetin alfa. Fever is not a typical finding associated with epoetin alfa therapy.
