Correct Answer: C

Rationale: The correct answer is C because bending at the hips can dislocate the hip joint in clients who have had a total hip arthroplasty. This movement should be avoided to prevent complications post-surgery. Choices A, B, and D are all correct statements for a client who has had a total hip arthroplasty. Avoiding prolonged sitting, crossing legs, and using a raised toilet seat are all appropriate measures to ensure proper healing and prevent complications.

Correct Answer: B

Rationale: The correct answer is B: Pallor. Pallor, which is paleness of the skin, is a common sign of anemia due to a decreased number of red blood cells or hemoglobin levels. This results in reduced oxygen-carrying capacity, leading to the paleness of the skin. Choice A, increased appetite, is not typically associated with anemia. Choice C, tachycardia (increased heart rate), can be present in anemia as the body compensates for decreased oxygenation. Choice D, hypertension (high blood pressure), is not a common finding in anemia; instead, low blood pressure may be observed due to decreased blood volume.

Correct Answer: B

Rationale: When a patient presents with confusion, the best initial action is to perform a neurological assessment. This assessment helps in identifying potential causes of confusion such as neurological issues, infections, metabolic abnormalities, or medication side effects. Administering IV fluids (Choice A) may be necessary based on assessment findings, but it is not the first step. Administering electrolytes (Choice C) would also depend on the assessment results. Preparing for a CT scan (Choice D) may be indicated later in the diagnostic process but is not the initial action when a patient presents with confusion.

Correct Answer: A

Rationale: The best intervention for a patient experiencing severe hypoglycemia is to administer IV dextrose. This intervention is necessary to rapidly raise blood sugar levels in critical situations. Administering oral glucose may not be effective in severe cases as the patient may be unable to consume it. Monitoring blood sugar levels and rechecking blood sugar in 15 minutes are important steps but not the initial best intervention for severe hypoglycemia.

Correct Answer: A

Rationale: The correct answer is A, Broccoli. Foods high in tyramine, such as broccoli, should be avoided when taking MAOIs like phenelzine to prevent a hypertensive crisis. Yogurt, cream cheese, and fruit juice do not contain significant levels of tyramine and can be safely consumed while on phenelzine.
