Correct Answer: A

Rationale: The correct answer is to administer oxygen. Post-surgery, confusion in a patient could be due to hypoxia, a condition where the body is deprived of an adequate oxygen supply. Administering oxygen helps address hypoxia promptly, improving oxygen levels in the body and potentially resolving the confusion. Repositioning the patient, checking oxygen saturation, and performing a neurological exam may be important interventions but addressing hypoxia with oxygen administration takes precedence as the priority action.

Correct Answer: A

Rationale: When a client receiving a blood transfusion develops a fever, the priority action for the nurse is to stop the transfusion immediately. A fever during a blood transfusion may indicate a transfusion reaction, and stopping the transfusion is crucial to prevent further complications. Administering an antihistamine (choice B) or a diuretic (choice C) without assessing and addressing the potential transfusion reaction can be harmful. Increasing the transfusion rate (choice D) is contraindicated as it can exacerbate any adverse reactions the client is experiencing.

Correct Answer: B

Rationale: The correct answer is B: 'Increase your intake of whole grains.' Whole grains are beneficial for individuals with hypertension as they can help promote heart health. Whole grains are high in fiber, which can help lower blood pressure. Option A is incorrect as fluid intake should be adequate but not restricted to 2 liters per day. Option C is incorrect as it is recommended to have smaller, more frequent meals rather than 3 large meals to help manage hypertension. Option D is incorrect; although foods high in potassium can be beneficial for hypertension, the most appropriate dietary modification to include in this scenario is increasing whole grain intake.

Correct Answer: D

Rationale: The correct answer is D: Weight. Weight monitoring is essential to assess the effectiveness of desmopressin therapy, as fluid retention is a common side effect. Monitoring fasting blood glucose (choice A) is not directly related to desmopressin therapy for diabetes insipidus. Monitoring carbohydrate intake (choice B) may be important in diabetes management but is not specific to desmopressin therapy. Hematocrit (choice C) monitoring is not a primary concern when managing diabetes insipidus with desmopressin.

Correct Answer: B

Rationale: The correct answer is B. Limiting protein intake is crucial for clients with chronic kidney disease as it helps prevent further kidney damage. Increasing intake of potassium-rich foods (choice A) is not recommended for clients with kidney disease as high potassium levels can be harmful. Avoiding foods high in phosphorus (choice C) is important, but limiting protein intake is a higher priority. Increasing dairy product intake (choice D) is not ideal for clients with kidney disease as they may need to monitor their phosphorus intake from such foods.
