Correct Answer: A

Rationale: The correct answer is A: Inspect feet daily for cuts and sores. Clients with diabetes are at an increased risk of foot complications, so it is essential to check for any cuts, sores, or injuries daily to prevent infections and complications. Soaking feet in warm water daily (choice B) is not recommended as it can lead to skin breakdown. Wearing closed-toe shoes at all times (choice C) is not advisable as it can cause excessive pressure and friction. Trimming toenails straight across (choice D) is the correct method to prevent ingrown toenails, not trimming them in a rounded shape.

Correct Answer: A

Rationale: Corrected Rationale: When administering warfarin, it is crucial to verify the patient's INR levels. INR monitoring is essential to ensure that the patient is receiving the correct dose of warfarin for their condition and to minimize the risk of bleeding. Choices B, C, and D are incorrect because administering warfarin with food, monitoring blood glucose levels, and assessing liver function are not directly related to the safe administration and monitoring of warfarin therapy.

Correct Answer: B

Rationale: Muscle twitching and a skin rash may indicate exposure to pesticides, which requires immediate intervention due to potential toxicity. Fatigue and fever (Choice A) are non-specific symptoms that may indicate various conditions but do not directly indicate pesticide exposure. Blurred vision (Choice C) and nasal congestion (Choice D) are also non-specific symptoms and are less likely to be related to pesticide exposure compared to muscle twitching and a skin rash.

Correct Answer: D

Rationale: When a client is receiving digoxin therapy, it is crucial for the nurse to monitor liver function, serum electrolytes (especially potassium levels), and blood pressure. Digoxin is known to affect the heart's electrical activity and can lead to toxic effects if not managed properly. Monitoring liver function helps to assess the drug's metabolism and excretion. Checking serum electrolytes, especially potassium, is essential because digoxin toxicity can be exacerbated by electrolyte imbalances, particularly hypokalemia. Monitoring blood pressure is necessary because digoxin can influence cardiac contractility and heart rate, potentially affecting blood pressure. Therefore, monitoring all these parameters is vital to ensure the client's safety and therapeutic effectiveness of digoxin. Choices A, B, and C are incorrect because monitoring only one or two of these parameters may not provide a comprehensive assessment of the client's response to digoxin therapy.

Correct Answer: C

Rationale: The correct answer is C. Stage 2 ulcers involve partial-thickness skin loss with visible and superficial damage, which may appear as an abrasion, blister, or shallow crater. Choice A describes a Stage 1 pressure ulcer characterized by intact skin with nonblanchable redness. Choice B describes a Stage 3 pressure ulcer with full-thickness tissue loss and damage to the subcutaneous tissue. Choice D is indicative of a Stage 4 pressure ulcer, involving full-thickness tissue loss with damage extending to muscle or bone.
