Correct Answer: B

Rationale: An elevated WBC count 48 hours postoperatively may indicate an infection and should be reported to the provider. Choice A, a heart rate of 90/min, is within normal limits and not a concerning finding postoperatively. Choice C, urinary output of 75 mL in the past 4 hours, may indicate decreased renal perfusion, but an elevated WBC count is a more urgent finding. Choice D, a temperature of 37.8°C (100°F), which is slightly elevated, could be indicative of the body's normal response to surgery and is not as alarming as an elevated WBC count.

Correct Answer: D

Rationale: An absent gag reflex is a critical finding that requires immediate intervention to prevent aspiration. This can lead to the aspiration of oral or gastric contents into the lungs, potentially causing serious respiratory complications. Oxygen saturation of 95% is within the normal range, a blood pressure of 130/85 mm Hg is also within normal limits, and coughing up small amounts of sputum is an expected finding after a bronchoscopy procedure.

Correct Answer: C

Rationale: The correct answer is C: Potassium 5.2 mEq/L. A potassium level of 5.2 mEq/L is elevated and should be monitored in clients taking spironolactone, which is a potassium-sparing medication. Monitoring potassium levels is crucial as spironolactone can cause hyperkalemia. Choices A, B, and D are incorrect because sodium, calcium, and magnesium levels are not typically affected by spironolactone. Therefore, the nurse should primarily focus on monitoring the potassium levels in this scenario.

Correct Answer: C

Rationale: The correct answer is lean beef because it is a good source of protein and essential nutrients. When providing dietary recommendations to clients with hypertension, it is important to focus on lean protein sources to promote a balanced diet. Bananas, although a healthy fruit, may not be the best choice due to their high potassium content, which can sometimes be a concern for individuals with hypertension. Whole grains are generally a good choice, but lean protein like beef is more suitable in this scenario. Canned soup often contains high levels of sodium, which is not recommended for individuals with hypertension.
