Correct Answer: C

Rationale: The correct answer is C: Cyanosis of the lips and nail beds. Cyanosis is a late sign of hypoxia and indicates severe oxygen deprivation, requiring immediate intervention in clients with pneumonia. Reporting this finding promptly is crucial to prevent further complications. Choices A, B, and D are incorrect because increased appetite, productive cough with green sputum, and mild shortness of breath are common findings in clients with pneumonia and may not require immediate intervention unless they worsen or are accompanied by other concerning symptoms.

Correct Answer: D

Rationale: A serum creatinine level of 3.0 mg/dL indicates impaired kidney function, which is a concern when prescribing spironolactone as it can further affect renal function. Elevated serum creatinine levels may suggest decreased renal clearance of spironolactone, leading to potential toxicity. Potassium, calcium, and magnesium levels are within normal ranges and not directly related to spironolactone therapy. Therefore, the nurse should report the elevated serum creatinine level to the provider for further evaluation and possible dosage adjustment.

Correct Answer: C

Rationale: The correct answer is C. Levothyroxine is a lifelong medication for clients with hypothyroidism, and it should be taken as prescribed. Choice A is incorrect because levothyroxine should be taken on an empty stomach. Choice B is incorrect because levothyroxine is usually taken in the morning on an empty stomach. Choice D is incorrect because stopping the medication abruptly can have adverse effects on thyroid function.

Correct Answer: B

Rationale: The correct answer is B because swelling in the hands is a potential sign of worsening preeclampsia, and the client should report this to their provider. Choice A is incorrect since aspirin is not recommended in preeclampsia. Choice C is incorrect as calcium intake is not directly related to preventing seizures in preeclampsia. Choice D is incorrect because protein restriction is not the standard management for preventing further kidney damage in preeclampsia.

Correct Answer: C

Rationale: The correct position for a client immediately postoperative following a hip arthroplasty is the lateral position with an abduction pillow between the legs. This position helps prevent dislocation of the hip prosthesis and maintains proper alignment of the hip joint. Supine position with legs extended (Choice A) may put stress on the hip joint, Semi-Fowler's position with legs bent (Choice B) may not provide adequate support and alignment, and prone position with legs elevated (Choice D) is not recommended after hip arthroplasty as it can compromise the surgical site and increase the risk of complications.
