Correct Answer: B

Rationale: The correct answer is to ensure the client consumes adequate protein. Protein is essential for wound healing as it supports tissue repair. Applying heat to the surgical site (choice A) is not recommended as it can increase inflammation. Although ambulation (choice C) is beneficial for circulation and preventing complications, it is not directly related to promoting wound healing. Instructing the client to drink 4 liters of water daily (choice D) is excessive and not specifically related to wound healing in this context.

Correct Answer: B

Rationale: Clear fluid draining from the ear can indicate cerebrospinal fluid leakage, which is a serious concern after a head injury. This leakage can signify a skull fracture or damage to the meninges, potentially leading to infection. Therefore, it should be reported immediately for further evaluation and management. Choices A, C, and D are typical findings after head trauma and are not as urgent as the presence of clear fluid draining from the ear.

Correct Answer: A

Rationale: Administering oxygen and seeking emergency help are crucial initial steps in managing a patient with suspected myocardial infarction (MI). Oxygen helps to improve oxygenation to the heart muscle, reducing its workload and preventing further damage. Calling for emergency help ensures timely access to advanced medical care, including interventions like thrombolytics. Monitoring vital signs and providing pain relief are important but secondary to the immediate need for oxygen and emergency assistance. Providing nitroglycerin and thrombolytics should be done under medical supervision and following appropriate protocols, not as the first step. Administering diuretics and altering the patient's diet are not indicated in the acute management of MI.

Correct Answer: D

Rationale: When dealing with a client with anorexia nervosa who insists on working out constantly, it is crucial to address the situation sensitively. Speaking to the client privately to uncover the source of the obsession is the most appropriate action. This approach allows the healthcare professional to understand the underlying reasons for the behavior and work towards a solution together. Choices A and B could potentially exacerbate the client's condition by either enabling the behavior or imposing restrictions without addressing the root cause. While choice C is important, simply discussing the risks may not address the client's compulsion to exercise excessively.

Correct Answer: D

Rationale: The correct answer is D: Oxygen saturation. The priority assessment in this situation is oxygen saturation because postoperative clients are at risk for respiratory complications, such as hypoxia due to factors like anesthesia effects, impaired lung function, or pain interfering with deep breathing. Monitoring oxygen saturation is crucial to detect any respiratory compromise early. Capillary refill, bowel sounds, and temperature are important assessments but are not the priority in this immediate postoperative period.
