Correct Answer: B

Rationale: The correct answer is to monitor the client's respiratory rate. This assessment is crucial in the postoperative period to detect any respiratory complications such as hypoxia or respiratory distress. Assessing pain level (Choice A) is important but may not be the top priority as respiratory status takes precedence. Measuring blood pressure (Choice C) is also important but not as critical immediately postoperatively as monitoring respiratory function. Checking bowel sounds (Choice D) is relevant for assessing gastrointestinal function but is typically not the top priority in the immediate postoperative phase.

Correct Answer: D

Rationale: A WBC count of 15,000/mm³ is elevated and may indicate infection, which should be reported. High WBC count is a sign of inflammation or infection, and in a postoperative client, it can be indicative of surgical site infection or another complication. Urinary output, serosanguineous wound drainage, and a heart rate of 94/min are all within normal ranges for a client post cholecystectomy and do not raise immediate concerns for infection or complications.

Correct Answer: A

Rationale: The most important nursing intervention for a patient with a suspected pulmonary embolism is to administer anticoagulants. Anticoagulants help prevent further clot formation in the patient's blood vessels, reducing the risk of complications such as worsening of the pulmonary embolism or development of new clots. Administering oxygen (Choice B) may be necessary to support the patient's oxygenation, but anticoagulants take precedence as they target the underlying cause of the pulmonary embolism. Repositioning the patient (Choice C) and monitoring oxygen saturation (Choice D) are important aspects of patient care but are not the primary intervention for a suspected pulmonary embolism.

Correct Answer: C

Rationale: A respiratory rate of 26/min is a sign of respiratory distress and should be reported promptly in a client with pneumonia. Rapid breathing can indicate inadequate oxygenation and ventilation, which may lead to respiratory failure. Crackles in the lung bases are common in pneumonia but may not be as urgent as a high respiratory rate. A blood pressure of 100/64 mm Hg is slightly low but may not be immediately life-threatening. A heart rate of 86/min is within the normal range for an adult and is not the most critical finding to report.

Correct Answer: A

Rationale: The correct action when digitally evacuating stool from a client with a fecal impaction is to insert a lubricated gloved finger and advance along the rectal wall. This technique helps prevent trauma to the client. Choice B is incorrect because stimulating peristalsis is not the appropriate action for digitally evacuating stool. Choice C is incorrect as applying pressure to the abdomen can be uncomfortable and ineffective. Choice D is also incorrect because increasing fluid intake is not directly related to the digital evacuation procedure.
