Correct Answer: C

Rationale: The correct answer is C. Cool feet bilaterally in a client with a long leg cast may indicate compromised circulation, which is a medical emergency that requires immediate intervention. Choices A, B, and D do not present immediate life-threatening conditions. Tingling in the fingers following a thyroidectomy may indicate hypocalcemia but does not require immediate attention. Dark, foul-smelling urine with decreased urine output indicates a possible urinary tract infection or dehydration but can be addressed after attending to the client with compromised circulation. A productive cough and a normal oral temperature do not suggest an urgent condition compared to compromised circulation in a client with a long leg cast.

Correct Answer: B

Rationale: The correct answer is Baked chicken breast. It is low in sodium and a healthy option for clients with hypertension. Canned tomato soup and processed cheese are typically high in sodium, which is not recommended for individuals with hypertension. Pickled vegetables are also high in sodium and should be avoided in a hypertension-friendly diet.

Correct Answer: C

Rationale: A temperature of 38.2°C (100.8°F) suggests the possibility of an underlying infection or fever, which should be evaluated before proceeding with the transfusion to prevent complications. Elevated temperature can indicate an immune response to incompatible blood components, increasing the risk of a transfusion reaction. The other vital signs and lab results provided are within acceptable ranges for administering packed RBCs, making choices A, B, and D less likely to cause a delay in the transfusion.

Correct Answer: A

Rationale: The correct answer is A: 'If I eat 500 fewer calories per day, I should lose 1 pound per week.' This statement is accurate because a reduction of 500 calories per day typically results in a weight loss of 1 pound per week. This is based on the principle that a calorie deficit of 3,500 calories equals about 1 pound of body fat. Choices B, C, and D are incorrect because they do not align with the established relationship between calorie reduction and weight loss. Eating 450 fewer calories per day would not lead to a weight loss of 2 pounds per week; similarly, reducing calories by 250 or 300 per day would not result in losing 2 pounds or 1 pound per week, respectively.

Correct Answer: C

Rationale: The correct action for the nurse to take when caring for a client with multiple sclerosis reporting diplopia is to recommend alternating eye patches during the day. This strategy can help relieve diplopia (double vision) by allowing each eye to rest alternately, reducing eye strain. Encouraging the client to focus on a distant object (Choice A) is not an appropriate intervention for diplopia in this case. Applying a warm compress to the client's eyes (Choice B) and administering artificial tears (Choice D) are not effective interventions for diplopia associated with multiple sclerosis.
