Correct Answer: C

Rationale: The correct answer is C: Wear gloves for blood/body fluid contact. This is the most appropriate action for infection control when caring for a patient with AIDS because HIV is primarily transmitted through blood and certain body fluids. Wearing gloves when coming into contact with blood or body fluids reduces the risk of transmission. Explanation for why other choices are incorrect: A: Wearing gloves at all times may not be necessary and can lead to unnecessary waste of resources. B: Wearing gown and mask at all times is excessive and not indicated unless there is a risk of exposure to blood or body fluids. D: Wearing a mask during patient contact times is not necessary unless there is a risk of exposure to respiratory secretions.

Correct Answer: D

Rationale: The correct answer is D - Check for a gag reflex before allowing the patient to drink. This is important after a bronchoscopy to prevent aspiration. Step 1: Assessing gag reflex ensures the patient can protect their airway. Step 2: Aspiration risk is high post-bronchoscopy due to sedation and possible throat numbness. Step 3: Allowing fluids without confirming gag reflex can lead to aspiration pneumonia. Other choices are incorrect. A: Ordering a meal immediately is inappropriate after NPO period. B: Encouraging fluids without assessing gag reflex may lead to aspiration. C: Monitoring consciousness is important but not directly related to post-bronchoscopy care.

Correct Answer: B

Rationale: The correct answer is B: Pathologic bone fractures. In multiple myeloma, there is an increase in osteoclast activity leading to bone destruction, making patients prone to pathologic fractures. Chronic liver failure (A), acute heart failure (C), and hypoxemia (D) are not directly associated with multiple myeloma pathophysiology. This highlights the importance of understanding the disease process to determine the correct answer.

Correct Answer: C

Rationale: The correct answer is C: Fat. Excessive ingestion of fat has been linked to autoimmunity due to its potential to trigger inflammation in the body, which can disrupt the immune system's balance and lead to autoimmune responses. High-fat diets have been associated with increased production of pro-inflammatory molecules, impacting immune function negatively. Protein (choice A) is essential for immune function, vitamin A (choice B) supports immune responses, and zinc (choice D) is crucial for immune system regulation. However, excessive intake of these nutrients typically does not directly lead to autoimmunity like excessive fat consumption does.

Correct Answer: D

Rationale: The correct answer is D: Assess swallowing reflex. This is crucial for a patient with Bell's Palsy as it can affect their ability to swallow properly, leading to inadequate nutrition intake. By assessing the swallowing reflex, the nurse can determine if the patient is at risk of aspiration or difficulty in eating, which directly impacts their nutrition status. Monitoring meal trays (A) may not provide accurate information on actual food intake. Checking weights (B) only gives limited information on nutrition status. Measuring intake and output (C) is important for fluid balance but may not directly reflect adequate nutrition intake.
