Correct Answer: C

Rationale: The correct answer is C: 'Avoid crossing your legs when sitting.' After a total hip arthroplasty, it is important for clients to avoid crossing their legs to prevent complications such as dislocation. Crossing the legs can put strain on the new hip joint, increasing the risk of dislocation. Choice A is incorrect as crossing legs can be harmful. Choice B is incorrect as bending at the waist can strain the hip joint, leading to complications. Choice D is incorrect as using a raised toilet seat is recommended after hip surgery to prevent excessive bending at the hip joint.

Correct Answer: A

Rationale: The correct answer is to administer epinephrine. Epinephrine is the first-line treatment for severe allergic reactions as it helps reverse the symptoms rapidly by constricting blood vessels, increasing heart rate, and opening airways. Antihistamines (Choice B) may help with mild allergic reactions but are not effective for severe cases. Corticosteroids (Choice C) are used to reduce inflammation and are typically not the first-line treatment for acute severe allergic reactions. Administering oxygen (Choice D) may be necessary to support breathing in severe cases, but epinephrine is the primary treatment to reverse the allergic reaction symptoms.

Correct Answer: B

Rationale: The correct answer is B. The adhesive bandage should be removed 3 days after a laparoscopic cholecystectomy to allow the incision to heal properly. Choice A is incorrect as the client should start with a clear liquid diet and advance to a regular diet as tolerated. Choice C is incorrect because the client should gradually increase activity levels as tolerated. Choice D is incorrect as the client should avoid tub baths and opt for showers to prevent infection and promote healing.

Correct Answer: B

Rationale: The correct answer is B: 'Take this medication at the same time every day.' It is crucial to take levothyroxine at the same time each day to maintain consistent thyroid hormone levels. Choice A is incorrect because levothyroxine should be taken on an empty stomach, usually in the morning. Choice C is important but not specific to the administration of levothyroxine. Choice D is incorrect as antacids can interfere with the absorption of levothyroxine.

Correct Answer: A

Rationale: The correct answer is to administer epinephrine. Epinephrine is the first-line treatment for severe allergic reactions because it rapidly reverses the symptoms of anaphylaxis by constricting blood vessels, increasing heart rate, and relaxing airway muscles. Corticosteroids, although helpful to reduce inflammation, are not the priority in the acute management of severe allergic reactions. Oxygen may be needed to support breathing, but it is not the initial priority. Antihistamines are not as effective as epinephrine in treating severe allergic reactions and should not be the first intervention.
