Nursing Elites

1. A client with a history of heart failure is prescribed spironolactone. The nurse should monitor for which potential side effect?

• A. Hyperkalemia
• B. Hypokalemia
• C. Hyponatremia
• D. Hypernatremia

Correct answer: A

Rationale: The correct answer is A: Hyperkalemia. Spironolactone is a potassium-sparing diuretic, which can lead to an excess of potassium in the body, causing hyperkalemia. This medication inhibits the action of aldosterone, leading to decreased potassium excretion and potential retention. Monitoring potassium levels is essential to prevent complications such as cardiac arrhythmias, especially in clients with heart failure.

2. A client has been diagnosed with open-angle glaucoma. The healthcare provider prescribes pilocarpine 1% eye drops. The nurse explains that which action of this drug makes it a useful treatment for the client's condition?

• A. The ciliary muscle contracts, increasing the outflow of aqueous humor in the eye.
• B. Ciliary muscles are paralyzed to decrease accommodation.
• C. Bilateral mydriasis with cycloplegia is accomplished.
• D. The production of aqueous humor in the eyes is decreased.

Correct answer: A

Rationale: Pilocarpine, a cholinergic agent, stimulates the ciliary muscle to contract, which opens the trabecular meshwork and facilitates the outflow of aqueous humor, reducing intraocular pressure. This mechanism helps in managing open-angle glaucoma by improving drainage and lowering pressure within the eye. Choice A is correct because the contraction of the ciliary muscle increases the outflow of aqueous humor, aiding in the treatment of open-angle glaucoma. Choices B, C, and D are incorrect because they do not describe the mechanism of action of pilocarpine in treating glaucoma.

3. A client is receiving metronidazole for Clostridium difficile pseudomembranous colitis. Which information should the nurse include in this client's medication teaching plan?

• A. Drink adequate water daily
• B. Take with food
• C. Avoid alcohol consumption
• D. Store medication in the refrigerator

Correct answer: C

Rationale: The correct information to include in the medication teaching plan for a client receiving metronidazole for Clostridium difficile pseudomembranous colitis is to avoid alcohol consumption. Metronidazole can cause a disulfiram-like reaction when combined with alcohol, leading to symptoms such as nausea, vomiting, flushing, and headache. Therefore, it is crucial for the client to abstain from alcohol while taking this medication to prevent adverse effects and ensure treatment effectiveness. Choices A, B, and D are incorrect. Drinking adequate water daily is a general health recommendation but not specific to metronidazole use. Taking with food is not necessary for metronidazole, and in fact, it is recommended to be taken on an empty stomach for better absorption. Storing the medication in the refrigerator is also incorrect, as metronidazole should be stored at room temperature.

4. A client with chronic kidney disease is prescribed lanthanum carbonate. The nurse should monitor for which potential side effect?

• A. Hypercalcemia
• B. Hypocalcemia
• C. Hyperkalemia
• D. Hypokalemia

Correct answer: A

Rationale: Lanthanum carbonate is prescribed in chronic kidney disease to bind dietary phosphorus in the gastrointestinal tract. This action can lead to decreased phosphorus absorption and potential hypercalcemia due to the increased serum calcium levels. Therefore, the nurse should monitor the client for signs and symptoms of hypercalcemia, such as confusion, fatigue, and muscle weakness. Choices B, C, and D are incorrect as lanthanum carbonate's mechanism of action does not lead to hypocalcemia, hyperkalemia, or hypokalemia.

5. A client taking long-term steroids also has ranitidine prescribed. The nurse provides which explanation as to why these drugs are given together?

• A. Ranitidine reduces the risk of ulcers associated with steroids.
• B. Ranitidine decreases the risk of infection associated with steroids.
• C. Ranitidine decreases blood sugar elevations associated with steroids.
• D. Ranitidine reduces sodium retention associated with steroid usage.

Correct answer: A

Rationale: The correct answer is A. Ranitidine is prescribed with long-term steroids to reduce the risk of ulcers associated with steroid therapy. Although steroids can increase the risk of ulcers due to their effect on the gastrointestinal system, ranitidine works by reducing stomach acid production, thus helping to prevent ulcer formation. Choices B, C, and D are incorrect as ranitidine is not given to decrease the risk of infection, reduce blood sugar elevations, or reduce sodium retention associated with steroid usage.
