Correct Answer: D

Rationale: In a urinalysis, a pH of 6 is within the normal range (typically between 4.6 and 8); a specific gravity of 1.015 is considered normal (usually ranging between 1.005 to 1.030); and a negative glucose result is also normal. Therefore, choices A, B, and C are correct as they fall within the normal values for a urinalysis. Choices A, B, and C are the correct answers, as the pH, specific gravity, and glucose levels are within the normal range for a urinalysis. Choice D is correct because all the listed values are normal. Choices A, B, and C are the correct options as they meet the criteria for normal urinalysis values. The other choices do not fall within the normal range for a urinalysis.

Correct Answer: A

Rationale: Oliguria, tachycardia, and abdominal cramping are signs of hyperkalemia, so the nurse should request an order for serum electrolytes to assess the patient's potassium levels. Encouraging the patient to consume less fluids would not address the underlying issue of potential hyperkalemia. Reporting symptoms of hyperkalemia to the provider is not as proactive as directly requesting serum electrolytes. Increasing the patient's potassium dose would worsen hyperkalemia, which is already suspected based on the symptoms presented.

Correct Answer: C

Rationale: After pericardiocentesis for cardiac tamponade, the nurse should assess for distant muffled heart sounds that were noted before the procedure. If these sounds return, it could indicate recurring pericardial effusion and potential tamponade. Therefore, the correct answer is the return of distant muffled heart sounds (Option C). Decreasing pulse (Option A) and falling central venous pressure (Option D) are not specific signs of recurring tamponade. Rising blood pressure (Option B) is also not a typical sign of tamponade recurrence; in fact, hypotension is more commonly associated with tamponade.

Correct Answer: A

Rationale: When erythromycin and cefaclor are taken together, erythromycin can inhibit the metabolism of cefaclor, leading to elevated cefaclor levels and potentially causing adverse effects. This results in a decrease in the effectiveness of cefaclor. Therefore, the nurse should discuss this potential drug interaction with the provider to consider an alternative treatment or adjust the dosages to prevent complications. Choices B, C, and D are incorrect because the concern lies with the effect on cefaclor when combined with erythromycin, not the effect on erythromycin itself.

Correct Answer: C

Rationale: The client is exhibiting symptoms of pericarditis, which can occur with chronic kidney disease. Continuity of care is crucial to assess subtle changes in clients' conditions. Therefore, the registered nurse (RN) who previously cared for this client should be assigned again. Float nurses may lack knowledge of the unit and its clients, potentially leading to oversight of critical details. The licensed practical nurse, while experienced, may not possess the advanced assessment skills and education level of an RN to effectively evaluate and manage pericarditis in this client.
