Correct Answer: C

Rationale: The correct answer is C. A serum potassium level of 3.2 mEq/L indicates hypokalemia, a potential complication of furosemide therapy, and should be reported immediately. Hypokalemia can lead to serious cardiac dysrhythmias. Choices A, B, and D are important assessments but are not as critical as managing serum potassium levels in a client receiving furosemide for heart failure.

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: 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: In this scenario, the client is experiencing frequent contractions with a short duration and an elevated fetal heart rate, indicating potential fetal distress. Discontinuing the oxytocin infusion is crucial to prevent further complications and restore normal fetal parameters. Increasing or maintaining the oxytocin infusion could exacerbate the situation, leading to more distress for the fetus. Decreasing the oxytocin infusion may not be sufficient to address the current issue and could delay the improvement of fetal well-being.

Correct Answer: B

Rationale: When a patient presents with confusion, the best initial action is to perform a neurological assessment. This assessment helps in identifying potential causes of confusion such as neurological issues, infections, metabolic abnormalities, or medication side effects. Administering IV fluids (Choice A) may be necessary based on assessment findings, but it is not the first step. Administering electrolytes (Choice C) would also depend on the assessment results. Preparing for a CT scan (Choice D) may be indicated later in the diagnostic process but is not the initial action when a patient presents with confusion.
