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: Monitoring for suicidal thoughts is critical with paroxetine, an SSRI, as it carries a black box warning for increased suicide risk, especially in the early weeks of treatment for PTSD.
Choice A is incorrect because paroxetine is typically taken at bedtime, as it can cause sedation, not in the morning.
Choice B is incorrect because paroxetine takes 4-6 weeks to reduce PTSD symptoms like flashbacks, not immediate relief.
Choice C is incorrect because paroxetine should not be discontinued abruptly, even if symptoms improve, to avoid withdrawal or relapse; it requires provider guidance.

Correct Answer: B

Rationale:
Choice A is wrong because aspirin should not be given to children or adolescents with viral infections, as it can cause Reye's syndrome, a rare but potentially fatal condition that affects the liver and brain. This is because rubella is a highly contagious viral infection that can cause serious harm to the developing fetus if the pregnant person gets infected. Rubella can cause congenital rubella syndrome, which can result in hearing and vision loss, heart defects and other serious conditions in newborns.
Choice C is wrong because rubella does not require airborne precautions, which are used for diseases that can spread through very small droplets that can remain in the air for long periods of time, such as tuberculosis or measles. Rubella spreads through direct contact with saliva or mucus of an infected person, or through respiratory droplets from coughing or sneezing.
Therefore, standard and droplet precautions are sufficient to prevent transmission.
Choice D is wrong because Koplik spots are a characteristic sign of measles, not rubella. Koplik spots are small white spots that appear on the inside of the cheeks before the measles rash develops. Rubella causes a pink or red rash that usually starts on the face and moves down the body.

Correct Answer: A

Rationale: Performing exercises to improve balance and coordination is essential for clients with Parkinson's disease to maintain mobility, reduce fall risk, and manage motor symptoms like bradykinesia and rigidity.
Choice B is incorrect because Parkinson's medications (e.g., levodopa) are typically taken during the day on a strict schedule to control symptoms, not at bedtime, which may disrupt sleep.
Choice C is incorrect because high-protein meals can interfere with levodopa absorption, so they should be spaced out from medication doses, not avoided entirely.
Choice D is incorrect because a heating pad may not effectively relieve Parkinson's-related muscle stiffness and could cause burns if sensation is impaired.

Correct Answer: B

Rationale: Unilateral arm weakness is typical post-stroke due to hemispheric brain damage. Bilateral weakness, fever, or abdominal pain are not specific.
