Correct Answer: B

Rationale: The correct answer is B, Glycosylated hemoglobin (HbA1c). HbA1c provides a measure of long-term blood glucose control over the past 2-3 months. This test reflects the average blood glucose levels during this period, making it a valuable tool in managing diabetes. Choices A, C, and D are not indicators of long-term blood glucose control. Fasting blood glucose measures the current glucose level after a period of not eating, random blood glucose provides a snapshot of the current glucose level, and postprandial blood glucose measures the glucose level after a meal.

Correct Answer: A

Rationale: Monitoring the surgical site is crucial to identify early signs of infection post-surgery. Redness, swelling, warmth, or discharge at the surgical site can indicate an infection. While monitoring for fever (choice B) is important as fever can also be a sign of infection, it may not always present immediately post-surgery. Checking blood pressure (choice C) is essential for other purposes but not specifically for monitoring infection post-surgery. Checking for redness (choice D) is limited as redness alone may not always indicate an infection, so it is not as comprehensive as monitoring the surgical site.

Correct Answer: A

Rationale: Spinach is the correct answer because it is a good source of calcium. Since the client has eliminated dairy products due to lactose intolerance, which are a common source of calcium, increasing spinach consumption can help compensate for the lost calcium. Peanut butter, ground beef, and carrots are not significant sources of calcium and therefore not the best choice for this client.

Correct Answer: A

Rationale: The priority nursing action for a patient with respiratory distress is to administer oxygen. Oxygen therapy is crucial in improving oxygenation levels and relieving respiratory distress, making it the top priority intervention. Repositioning the patient, administering bronchodilators, or providing chest physiotherapy may be necessary interventions depending on the underlying cause, but ensuring adequate oxygen supply should take precedence in addressing respiratory distress.

Correct Answer: B

Rationale: The correct answer is B: 'Sleep with the head of your bed elevated.' Elevating the head of the bed helps reduce acid reflux by keeping the head higher than the stomach, preventing stomach acid from flowing back into the esophagus. Choices A, C, and D are incorrect. Avoiding eating small, frequent meals, lying down after eating, and drinking fluids with meals can exacerbate GERD symptoms by increasing stomach acid production and promoting acid reflux.
