1. Hydrochlorothiazide is classified as a

A. Anti-inflammatory
B. Antiarrhythmic
C. Diuretic
D. Antifungal

Correct answer: C

Rationale: Hydrochlorothiazide is classified as a diuretic. Diuretics are medications that help the body get rid of excess salt and water by increasing urine production, reducing fluid retention, and lowering blood pressure. Option A, Anti-inflammatory, is incorrect because hydrochlorothiazide does not primarily reduce inflammation. Option B, Antiarrhythmic, is incorrect because hydrochlorothiazide is not used to correct heart rhythm irregularities. Option D, Antifungal, is incorrect because hydrochlorothiazide is not used to treat fungal infections.

2. What is the primary action of warfarin as an anticoagulant?

A. Prevents the formation of blood clots
B. Dissolves existing blood clots
C. Dilates coronary arteries
D. Treats rhythm disturbances

Correct answer: A

Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.

3. A client is taking Spironolactone. Which of the following laboratory findings should the nurse monitor and report to the provider?

A. Sodium level of 138 mEq/L
B. Potassium level of 5.2 mEq/L
C. Chloride level of 100 mEq/L
D. Calcium level of 9.5 mg/dL

Correct answer: B

Rationale: The correct answer is B: Potassium level of 5.2 mEq/L. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia (elevated potassium levels). A potassium level of 5.2 mEq/L is considered elevated and should be reported to the provider for further assessment and management to prevent potential complications. Choices A, C, and D are not directly affected by Spironolactone and do not typically require immediate reporting unless there are other underlying issues or specific instructions for those electrolytes.

4. When administering an Antiulcer Agent, you should be more cautious when administering it to:

A. A healthy 27-year-old patient
B. Patient with renal failure
C. Elderly patients
D. Choices B & C

Correct answer: D

Rationale: When administering an antiulcer agent, caution is warranted in patients with renal failure due to the potential impact on drug metabolism and excretion. Additionally, elderly patients may be more susceptible to adverse effects from antiulcer agents due to age-related physiological changes. Therefore, it is important to be more cautious when administering antiulcer agents to patients with renal failure and elderly patients. Choice A, a healthy 27-year-old patient, would typically not require as much caution compared to patients with renal failure or elderly patients when administering antiulcer agents. Therefore, choices B & C are the correct options for increased caution.

5. A client is starting therapy with cisplatin. The healthcare provider should instruct the client to report which of the following adverse effects?

A. Tinnitus
B. Nausea
C. Constipation
D. Weight gain

Correct answer: A

Rationale: The correct answer is tinnitus. Cisplatin can cause ototoxicity, which may manifest as tinnitus. Tinnitus should be reported promptly to the healthcare provider to prevent further hearing damage.
