Correct Answer: C

Rationale: The correct instruction when taking alendronate is to remain upright for 30 minutes after administration. This helps prevent esophageal irritation, a known side effect of the medication. Option A is incorrect because alendronate should be taken in the morning on an empty stomach. Option B is incorrect as taking alendronate with food decreases its absorption. Option D is incorrect as alendronate should be swallowed whole with a full glass of water and not chewed.

Correct Answer: B

Rationale: The correct answer is B: 'I should increase my intake of vitamin D.' Adequate vitamin D intake is crucial for calcium absorption, which is essential for bone health and preventing osteoporosis. Avoiding weight-bearing exercises (choice A) would be detrimental as weight-bearing activities help improve bone density. Reducing dairy intake (choice C) is not recommended as dairy products are a good source of calcium. While increasing calcium intake (choice D) is important, ensuring sufficient vitamin D levels for proper absorption is equally crucial for bone health.

Correct Answer: D

Rationale: The correct answer is D. A cool left foot indicates impaired circulation, which could be a sign of compartment syndrome or impaired blood flow. This finding should be reported to the provider promptly for further evaluation and intervention. Serous drainage on the dressing is expected postoperatively and is not a concerning finding. A capillary refill of 2 seconds is within the normal range (less than 3 seconds is normal), indicating adequate peripheral perfusion. A heart rate of 62/min is also within the normal range for an adult, suggesting no immediate concern related to the surgery.

Correct Answer: B

Rationale: The correct answer is B: Barley soup. Barley contains gluten, which is harmful to individuals with celiac disease. Therefore, the nurse should instruct the client to avoid barley-containing foods like barley soup. Choices A, C, and D are safe options for individuals with celiac disease as they do not contain gluten. Rice, cornbread, and potatoes are gluten-free and can be included in the client's diet.

Correct Answer: A

Rationale: The correct answer is A: Serum glucose level. In Cushing's disease, elevated cortisol levels lead to increased gluconeogenesis, insulin resistance, and breakdown of proteins and fats, resulting in elevated blood glucose levels. This is known as hyperglycemia. The other options, including serum calcium level (choice B), lymphocyte count (choice C), and serum potassium level (choice D), are not typically affected by Cushing's disease. Therefore, they are incorrect choices.
