Correct Answer: A

Rationale: The correct answer is A: Assess the patient's level of understanding about diabetes management. This is the most important nursing action because it enables the nurse to tailor education and interventions to the patient's specific needs. By assessing the patient's understanding, the nurse can address any misconceptions, provide appropriate education, and promote self-management. Checking blood sugar levels every hour (B) is excessive and not necessary unless indicated. Instructing the patient to avoid all sugar-containing foods (C) is overly restrictive and not evidence-based. Ensuring the patient is compliant with their insulin regimen (D) is important but assessing understanding is crucial for effective diabetes management.

Correct Answer: B

Rationale: The correct answer is B: Alopecia. MOPP therapy for Hodgkin's disease commonly causes hair loss (alopecia), which directly affects body image. This is due to the impact on a person's physical appearance, leading to changes in self-perception and confidence. Cushingoid appearance (A) is a side effect of prolonged corticosteroid use, not typically associated with MOPP therapy. Temporary or permanent sterility (C) and pathologic fractures (D) are potential side effects of other cancer treatments but are not directly related to altering body image.

Correct Answer: D

Rationale: The correct answer is D because it directly asks for specific information about past hospitalizations, prompting Mr. Y to recall the last time he was admitted for chest pain. This question is open-ended, allowing Mr. Y to provide detailed information voluntarily. A is incorrect as it assumes Mr. Y has been hospitalized without directly asking for that information. B is a better choice but lacks specificity in requesting details about past hospitalizations. C is inappropriate as it assumes permission to access medical records without Mr. Y's consent.

Correct Answer: C

Rationale: The correct answer is C, stab wound to the chest. This injury is the highest priority because it poses the greatest risk to the client's life due to potential damage to vital organs and major blood vessels. Immediate intervention is crucial to prevent severe bleeding, pneumothorax, or cardiac tamponade. Treating this injury promptly can significantly increase the client's chances of survival. The other choices are incorrect because: A: An open leg fracture, while serious, does not typically pose an immediate life-threatening risk compared to a stab wound to the chest. B: An open head injury can be severe, but not all head injuries are immediately life-threatening. D: Traumatic amputation of a thumb, while traumatic and painful, is not a priority compared to injuries that directly threaten a client's life.

Correct Answer: C

Rationale: The correct answer is C: Assessing the patient's respiratory status. After administering pain medication, especially opioids, it is crucial to monitor the patient's respiratory status due to the risk of respiratory depression. This assessment is a priority because respiratory depression can be life-threatening. Other choices are not as immediate: A, assessing for addiction, can be done but is not as critical at this moment; B, assessing pain level, is important but comes after ensuring the patient's safety; D, assessing for infection, is not directly related to the immediate effects of pain medication.
