Correct Answer: C

Rationale:
Choice A is not a typical sign of coarctation of the aorta. Nosebleeds can be caused by many factors, such as dry air, allergies, trauma, or bleeding disorders.
Choice B is also not a common finding in coarctation of the aorta. In fact, patients with this condition may have high blood pressure in the upper extremities due to the increased resistance of the narrowed aorta. This is because coarctation of the aorta is a congenital condition where the aorta is narrow, usually in the area where the ductus arteriosus inserts. This causes a decrease in blood flow to the lower body, resulting in weak or absent pulses in the femoral arteries.

Correct Answer: B

Rationale: Tremors are a common finding in alcohol use disorder, especially during withdrawal, due to central nervous system hyperexcitability from chronic alcohol suppression.
Choice A is incorrect because hyperglycemia, not hypoglycemia, may occur due to alcohol's effect on liver glycogenolysis.
Choice C is incorrect because hypertension, not hypotension, is more common, especially during withdrawal or chronic use.
Choice D is incorrect because weight loss, not weight gain, is typical due to poor nutrition and increased metabolic demand.

Correct Answer: A

Rationale: This instruction will help the client to prevent venous stasis and thrombosis, which are common postoperative complications. Range-of-motion exercises promote blood circulation and prevent muscle atrophy and contractures.
Choice B is wrong because using an incentive spirometer every 4 hours is not related to promoting circulation, but rather to improving lung expansion and preventing atelectasis and pneumonia. Using an incentive spirometer is also important for postoperative clients, but it does not address the question.
Choice C is wrong because remaining on bed rest for 24 hours following the procedure is the opposite of promoting circulation. Bed rest increases the risk of venous stasis, thrombosis, and pulmonary embolism. Postoperative clients should be encouraged to ambulate as soon as possible, unless contraindicated.
Choice D is wrong because placing a pillow under your knees while in bed impairs circulation and increases the risk of thrombosis. Placing a pillow under the knees can cause pressure on the popliteal veins and reduce blood flow. Postoperative clients should avoid this position and keep their legs in a neutral or slightly elevated position.

Correct Answer: C

Rationale:
Choice A is wrong because it is not the most urgent question to ask the client. While it is important to assess the client's social relationships and possible peer rejection, this can be done after addressing the client's safety and mental status.
Choice B is wrong because it is not relevant to the client's current condition and might make the client feel defensive or stigmatized. The nurse should avoid asking questions that imply blame or judgment and focus on the client's strengths and coping skills. This is the priority question for the nurse to ask the client because it assesses the client's risk for suicide, which is a serious and potentially life-threatening complication of conduct disorder. The nurse should use a direct and nonjudgmental approach when asking about suicidal ideation and plan.
Choice D is wrong because it is not appropriate for the nurse to ask the client in an emergency department setting. This question might imply that the client is responsible for their conduct disorder, which is a complex and multifactorial mental health condition. The nurse should collaborate with the client and their family to develop a behavior management plan that involves positive reinforcement, limit setting, and consistent consequences.

Correct Answer: B

Rationale: Hypocalcemia is a potential complication after thyroidectomy due to accidental removal or damage to the parathyroid glands, which regulate calcium; symptoms like tetany or numbness should be monitored.
Choice A is incorrect because tachycardia is not a primary postoperative complication; it may occur with pain or hyperthyroidism but is less specific.
Choice C is incorrect because a fever of 37.5°C is not significant and may be a normal postoperative response, not a complication unless persistent.
Choice D is incorrect because increased appetite is not a typical postoperative complication; hypothyroidism may cause decreased appetite.
