1. Why is the combination drug trimethoprim-sulfamethoxazole (TMP-SMX) necessary?

Correct answer: B

Rationale: The correct answer is B: To decrease bacterial resistance. Trimethoprim-sulfamethoxazole (TMP-SMX) is a combination drug used to prevent bacterial resistance to sulfonamides. It works by targeting different steps in the bacterial metabolic pathway, making it harder for bacteria to develop resistance. Choice A is incorrect because the combination does not broaden the antibacterial spectrum; instead, it enhances effectiveness against specific bacteria. Choice C is incorrect as taste improvement is not the primary reason for combining these drugs. Choice D is incorrect because while combination therapy can sometimes help minimize toxic effects, the primary purpose in this case is to address bacterial resistance.

2. A 68-year-old client on day 2 after hip surgery has no cardiac history but reports having chest heaviness. The first nursing action should be to:

Correct answer: A

Rationale: The correct first nursing action when a client reports chest heaviness post-hip surgery is to gather more information through assessment. Inquiring about the onset, duration, severity, and precipitating factors of the heaviness is crucial to determine the cause. This approach helps the nurse to gather essential data to make an informed decision regarding the client's care. Administering oxygen (Choice B) may be indicated based on assessment findings, but it is crucial to assess first. Offering pain medication (Choice C) without further assessment is premature and may mask symptoms. Informing the physician (Choice D) should be done after a thorough assessment to provide comprehensive information for appropriate medical decision-making.

3. A client recovering from extracorporeal shock wave lithotripsy for renal calculi has an ecchymotic area on the right lower back. What action should the nurse take?

Correct answer: B

Rationale: After extracorporeal shock wave lithotripsy, ecchymosis can occur due to bleeding into the tissues from the shock waves. Applying an ice pack helps reduce the extent and discomfort of bruising. Administering fresh-frozen plasma and obtaining coagulation test results are not necessary as ecchymosis after this procedure is common and does not indicate a bleeding disorder that requires immediate intervention. Placing the client in the prone position will not address the bleeding or bruising in this situation.

4. A patient has begun taking spironolactone (Aldactone) in addition to a thiazide diuretic. With the addition of the spironolactone, the nurse will counsel this patient to

Correct answer: C

Rationale: When combining a potassium-sparing diuretic like spironolactone with a thiazide diuretic, there is an increased risk of hyperkalemia, especially in patients with poor renal function. Therefore, the patient should be educated to report any decrease in urine output, which could indicate a potential issue with kidney function. Choice A is incorrect because taking additional potassium supplements can further increase the risk of hyperkalemia. Choice B is incorrect as abdominal cramping is not a common side effect of spironolactone. Choice D is incorrect because the timing of medication administration is not directly related to the addition of spironolactone and thiazide diuretic; there is no specific recommendation to take these medications only at bedtime.

5. A 32-year-old female client complains of severe abdominal pain each month before her menstrual period, painful intercourse, and painful defecation. Which additional history should the nurse obtain that is consistent with the client's complaints?

Correct answer: B

Rationale: The correct answer is B: 'Inability to get pregnant.' The symptoms described in the client's complaints, which include severe abdominal pain before menstruation, painful intercourse, and painful defecation, are indicative of endometriosis. Endometriosis is a condition characterized by the abnormal presence of endometrial tissue outside the uterus, commonly leading to infertility. While choices A, C, and D may be associated with other conditions, they are not directly related to the symptoms described by the client, making them incorrect choices. Frequent urinary tract infections may suggest a different issue, premenstrual syndrome does not typically present with severe abdominal pain, and chronic use of laxatives is not a typical symptom of endometriosis.
