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.

Correct Answer: A

Rationale: Bruising is a common adverse effect of clopidogrel, an antiplatelet medication, due to its inhibition of platelet aggregation, increasing the risk of bleeding.
Choice B is incorrect because weight gain is not associated with clopidogrel; it may occur with other cardiac medications like beta-blockers.
Choice C is incorrect because tinnitus is not a typical side effect of clopidogrel; it is more associated with aspirin or quinine.
Choice D is incorrect because clopidogrel does not affect blood glucose levels; hyperglycemia is unrelated to its mechanism.

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: D

Rationale: Expecting a mild headache as a side effect is correct, as nitroglycerin causes vasodilation, which can lead to headaches; clients should be informed this is common and manageable with acetaminophen if needed.
Choice A is incorrect because, while taking up to three doses 5 minutes apart is correct, the nurse should also instruct the client to seek emergency care if pain persists after three doses.
Choice B is incorrect because nitroglycerin should be stored in a cool, dark place in its original container to maintain potency, not a warm, dry place.
Choice C is incorrect because nitroglycerin sublingual tablets are placed under the tongue to dissolve, not swallowed, for rapid absorption.

Correct Answer: D

Rationale: Dry mouth is a common adverse effect of duloxetine, an SNRI, due to its anticholinergic properties, and should be monitored to ensure client comfort and hydration.
Choice A is incorrect because duloxetine is more likely to cause weight gain or be weight-neutral, not weight loss.
Choice B is incorrect because hypotension is not a frequent side effect; orthostatic hypotension may occur but is less common.
Choice C is incorrect because tachycardia is not a primary side effect; it may occur with overdose or serotonin syndrome.
