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 client has a new prescription for Labetalol. Which of the following instructions should be provided?
- A. Take the medication with food.
- B. Monitor your blood glucose levels.
- C. Expect a rapid heart rate.
- D. Increase your intake of high-sodium foods.
Correct answer: A
Rationale: The correct answer is A: Take the medication with food. Labetalol should be taken with food to increase absorption and reduce the risk of orthostatic hypotension. Taking it with food helps in better absorption and minimizes the potential drop in blood pressure when standing up, which can occur with this medication. Choice B is incorrect as Labetalol is not primarily associated with affecting blood glucose levels. Choice C is incorrect as Labetalol is a beta-blocker that would actually lower heart rate, not increase it. Choice D is incorrect because increasing intake of high-sodium foods could counteract the antihypertensive effects of Labetalol.
3. A client with thrombophlebitis receiving heparin by continuous IV infusion asks the nurse how long it will take for the heparin to dissolve the clot. Which of the following responses should the nurse give?
- A. It usually takes heparin at least 2 to 3 days to reach a therapeutic blood level.
- B. A pharmacist is the person to answer that question.
- C. Heparin does not dissolve clots. It stops new clots from forming.
- D. The oral medication you will take after this IV will dissolve the clot.
Correct answer: C
Rationale: The correct response is C. Heparin does not dissolve clots; it prevents new clots from forming. Heparin works by inhibiting the formation of new clots and the extension of existing clots, rather than directly dissolving them. The client should be informed that the purpose of heparin therapy is to prevent the clot from getting larger and to reduce the risk of new clots forming. Choices A, B, and D are incorrect. Choice A talks about reaching a therapeutic blood level of heparin, which is not related to clot dissolution. Choice B deflects the question to a pharmacist without providing relevant information. Choice D inaccurately suggests that an oral medication will dissolve the clot, which is not the mechanism of action for heparin.
4. A client is receiving treatment with irinotecan. Which of the following findings should the nurse monitor?
- A. Diarrhea
- B. Hypertension
- C. Ototoxicity
- D. Neutropenia
Correct answer: A
Rationale: Corrected Rationale: Irinotecan is known to commonly cause diarrhea as an adverse effect due to its impact on the gastrointestinal tract. Therefore, the nurse should closely monitor the client for signs of diarrhea while receiving this treatment. Choices B, C, and D are incorrect because irinotecan is not typically associated with hypertension, ototoxicity, or neutropenia as primary adverse effects. While these side effects can occur with other medications, they are not the main concerns when monitoring a client receiving irinotecan.
5. When starting therapy with bicalutamide, a client should be instructed to monitor for which of the following adverse effects?
- A. Muscle pain
- B. Flushing
- C. Gynecomastia
- D. Hyperglycemia
Correct answer: C
Rationale: The correct answer is C: Gynecomastia. Bicalutamide, due to its antiandrogenic properties, can lead to gynecomastia in clients. This condition involves the development of breast tissue in males and is an important adverse effect to monitor when taking this medication. Choices A, B, and D are incorrect. Muscle pain and flushing are not commonly associated with bicalutamide use. Hyperglycemia is not a typical adverse effect of bicalutamide therapy.
