Correct Answer: A

Rationale: Rinsing the mouth after using ipratropium, an anticholinergic inhaler, prevents dry mouth and reduces the risk of oral candidiasis, a potential side effect.
Choice B is incorrect because ipratropium provides gradual bronchodilation and does not offer immediate relief; short-acting beta-agonists like albuterol are used for acute symptoms.
Choice C is incorrect because ipratropium is typically used 3-4 times daily, not every 2 hours as needed; overuse can cause side effects like tachycardia.
Choice D is incorrect because a spacer can be used with ipratropium to improve medication delivery, especially for clients with poor inhaler technique.

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: Rinsing the mouth after ipratropium prevents oral irritation or infection. It's used per schedule, relief is not immediate, and food is unrelated.

Correct Answer: A

Rationale: An uncontrollable urge to move the legs is a hallmark symptom of restless legs syndrome, often accompanied by uncomfortable sensations relieved by movement.
Choice B is incorrect because joint swelling is not associated with restless legs syndrome; it is more typical of arthritis.
Choice C is incorrect because fever is not a feature unless an infection or other condition is present.
Choice D is incorrect because weight gain is not a primary symptom; weight changes may occur secondary to medication or lifestyle.
