Correct Answer: C

Rationale: The correct answer is C: Apply petroleum jelly to the affected area. This is because petroleum jelly helps to soothe and protect the skin, reducing dryness and irritation caused by radiation therapy. Ice (A) can further damage the skin, shaving (B) can increase the risk of infection, and soap (D) can be too harsh on the sensitive skin. Therefore, instructing the patient to apply petroleum jelly is the most appropriate recommendation to promote skin healing and comfort.

Correct Answer: A

Rationale: The correct answer is A: Limit fluid and caffeine intake before bed. This recommendation addresses the issue of nocturia (frequent urination at night) by reducing the amount of urine produced before bedtime, therefore decreasing the need to get up during the night. Caffeine is a diuretic, so limiting its intake can also help reduce the frequency of urination. Choices B, C, and D do not directly address the underlying cause of nocturia and falling. Leaving the bathroom light on (choice B) may help with visibility but does not address the urinary problem. Kegel exercises (choice C) focus on pelvic floor muscles, not bladder muscles. Clearing the path to the bathroom (choice D) can prevent falls but does not address the urinary issue.

Correct Answer: B

Rationale: The correct answer is B: Importance of personal hygiene. Maintaining good personal hygiene is crucial for patients with HIV to prevent infections. This includes regular handwashing, oral care, and bathing. By emphasizing personal hygiene, the nurse can help the patient reduce the risk of opportunistic infections. Prophylactic antibiotics (choice A) are important but should be prescribed by the healthcare provider. Signs and symptoms of wasting syndrome (choice C) are significant, but focusing on prevention through hygiene is more practical. Adjusting antiretroviral dosages (choice D) is the responsibility of the healthcare provider, not the patient.

Correct Answer: A

Rationale: The correct answer is A: Depression. In the context of the stages of death and dying proposed by Elisabeth Kübler-Ross, a patient exhibiting signs of loss, grief, and intense sadness is likely in the depression stage. This stage involves feelings of hopelessness, despair, and sorrow as the patient comes to terms with the reality of their situation. Denial (choice B) is characterized by a refusal to accept the diagnosis, anger (choice C) involves feelings of resentment and frustration, and resignation (choice D) signifies a sense of acceptance and peace. In this scenario, the patient's emotional state aligns most closely with depression, indicating a deep sense of sadness and mourning.

Correct Answer: A

Rationale: The correct answer is A: Stop the infusion of magnesium. A magnesium level of 6 mg/dL is above the therapeutic range (4-7 mg/dL) for preeclamptic patients receiving magnesium sulfate. Continuing the infusion can lead to magnesium toxicity, causing respiratory depression, cardiac arrest, and neuromuscular blockade. Stopping the infusion is crucial to prevent further complications. Assessing the patient's respiratory rate (B) and deep tendon reflexes (C) are important, but stopping the infusion takes priority to prevent harm. Notifying the health care provider (D) is important but may delay immediate action to address the high magnesium level.
