Correct Answer: D

Rationale: The correct action for the nurse to take first is to ask the family what the provider has discussed with them. This allows the nurse to clarify any misunderstandings and ensures that the family is fully informed before providing further information. Option A is not the best choice because it assumes the need for more information without first understanding what has already been communicated. Option B is premature as the family may not be ready for grief counseling at this stage. Option C, although a good general practice, is not the most appropriate immediate action in this situation where clarifying existing information is crucial.

Correct Answer: A

Rationale: Lip-smacking is a symptom of tardive dyskinesia, a long-term side effect of antipsychotic medications like haloperidol, characterized by involuntary movements of the face and jaw. Agranulocytosis (Choice B) is a rare but serious side effect of some medications, characterized by a dangerously low white blood cell count. Clang association (Choice C) is a thought disorder characterized by the association of words based on sound rather than meaning. Alopecia (Choice D) refers to hair loss, which is not a known long-term side effect of haloperidol.

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: D

Rationale: The correct answer is D: Red, open sores in the mouth. Stomatitis, a common side effect of chemotherapy, presents with red, open sores in the mouth, which can be painful and increase the risk of infection. Choices A, B, and C are incorrect because stomatitis typically does not manifest as dry, cracked lips, bleeding gums, or foul-smelling breath.

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.
