Correct Answer: D

Rationale: The correct answer is D. Clients with diabetes should eat a snack if their blood glucose level is below 70 mg/dL, not 200 mg/dL. Option A is incorrect because checking blood glucose levels once a week may not provide adequate monitoring for someone with diabetes. Option B is incorrect as a strict limit of 50 grams of carbohydrates per day may not be suitable for everyone and can vary based on individual needs. Option C is incorrect as it is important for clients with diabetes to have a balanced diet that includes protein in moderation.

Correct Answer: C

Rationale: The correct answer is C. Doxazosin can cause orthostatic hypotension, leading to dizziness and falls if the client rises quickly from a seated position. Instructing the client to rise slowly when sitting up from bed helps prevent these adverse effects. Choices A, B, and D are incorrect because doxazosin does not directly relate to caloric intake, dietary fiber, or a specific time of day for administration.

Correct Answer: D

Rationale: The correct answer is to monitor the insertion site for redness. This intervention helps detect signs of infection early in clients with intraventricular catheters. Keeping the head of the bed elevated to 30 degrees is important for managing intracranial pressure but does not directly reduce the risk of infection. Administering IV antibiotics prophylactically is not recommended as a routine practice due to the risk of antibiotic resistance and should only be done based on culture results. Changing the catheter insertion site every 24 hours is unnecessary and increases the risk of introducing new pathogens.

Correct Answer: A

Rationale: The correct answer is to administer epinephrine. Epinephrine is the first-line treatment for a severe allergic reaction as it helps to constrict blood vessels, increase heart rate, and open airways, thereby improving breathing and circulation. Discontinuing the medication may not be sufficient to manage a severe allergic reaction as the allergen is already in the patient's system. Corticosteroids and antihistamines can be considered as complementary treatments but are not the primary immediate intervention required for a severe allergic reaction.

Correct Answer: C

Rationale: The correct instruction the nurse should include is to perform weight-bearing exercises regularly. Weight-bearing exercises help maintain bone density and reduce the risk of fractures in clients with osteoporosis. Increasing intake of calcium-rich foods (Choice A) is also beneficial for bone health. Avoiding weight-bearing exercises (Choice B) is incorrect as these exercises are essential for strengthening bones. Avoiding calcium supplements (Choice D) may not be necessary if the client's dietary intake is inadequate.
