Correct Answer: B

Rationale: The correct intervention for a client with nonblanchable erythema over the ischium is to teach the client to shift his weight every 15 minutes while sitting. This action helps relieve pressure on the affected area and prevents further skin breakdown. Placing the client upright on a donut-shaped cushion (Choice A) may not address the need for frequent weight shifts. Turning and repositioning the client every 3 hours (Choice C) is important for overall skin health but may not provide adequate relief for the specific area of nonblanchable erythema. Assessing pressure points every 24 hours (Choice D) is not frequent enough to prevent worsening of the skin condition in this case.

Correct Answer: A

Rationale: A heart rate of 78/min is within the normal range; however, postoperative patients require close monitoring for any signs of complications. While the heart rate is normal, other critical findings such as increased pain, excessive bleeding, or other concerning symptoms may need immediate attention. Choices B, C, and D all indicate normal postoperative vital signs and oxygen saturation levels, which do not raise immediate concerns requiring reporting to the provider.

Correct Answer: D

Rationale: Food exchange lists from the American Diabetes Association are a valuable resource for structured meal planning in individuals with diabetes. These lists categorize foods based on macronutrient content and help individuals plan balanced meals to manage blood sugar levels effectively. Personal blogs may not always provide accurate and evidence-based information. Food label recommendations from the Institute of Medicine are important but may not be as specific to meal planning for diabetes. Diabetes medication information is crucial but not the primary focus when providing dietary instructions.

Correct Answer: C

Rationale: The correct answer is C: Diaphoresis. Diaphoresis, which is excessive sweating, is a common sign of hypoglycemia due to the activation of the sympathetic nervous system. Tachycardia (choice A) is more commonly associated with hyperglycemia. Dry mouth (choice B) is not a typical finding in hypoglycemia but may be seen in hyperglycemia. Increased appetite (choice D) is not a typical sign of hypoglycemia and is more commonly associated with hyperglycemia.

Correct Answer: B

Rationale: The correct answer is B. An apical pulse below 60/min indicates bradycardia, a potential sign of digoxin toxicity. The nurse should report this finding to the provider for further evaluation and possible adjustment of the digoxin dose. Choice A, a potassium level of 4.2 mEq/L, is within the normal range (3.5-5.0 mEq/L) and does not indicate toxicity. Choice C, a digoxin level of 1 ng/ml, is within the therapeutic range (0.5-2 ng/ml) and is not suggestive of toxicity. Choice D, constipation for 2 days, is not directly related to digoxin administration and would not require an immediate report to the provider.
