A nurse is providing discharge instructions to the parent of a 10-year-old child following a cardiac catheterization. Which of the following instructions should the nurse include?
Give the child acetaminophen for discomfort.
Keep the child home for 1 week.
Assist the child to take a tub bath for the first 3 days.
Offer the child clear liquids for the first 24 hours.
The Correct Answer is A
Choice A rationale
Giving the child acetaminophen for discomfort is appropriate as it helps manage pain without interfering with the healing process.
Choice B rationale
Keeping the child home for 1 week is not necessary unless there are specific complications or instructions from the healthcare provider.
Choice C rationale
Assisting the child to take a tub bath for the first 3 days is not recommended as it may increase the risk of infection at the catheter insertion site.
Choice D rationale
Offering the child clear liquids for the first 24 hours is not necessary unless there are specific dietary restrictions from the healthcare provider.

Correct Answer is A
Explanation
Choice A rationale
Coronary arteries decrease in diameter leading to insufficient blood, oxygen, and nutrients reaching the heart muscle. This is correct because atherosclerosis, which is the buildup of plaque in the coronary arteries, causes the arteries to narrow. This narrowing reduces blood flow to the heart muscle, leading to ischemia and the manifestations of coronary artery disease, such as angina and myocardial infarction.
Choice B rationale
Manifestations occur due to dilation of coronary arteries with increased blood flow causing increased pressure. This is incorrect because the primary issue in coronary artery disease is the narrowing of the arteries, not their dilation. Increased blood flow and pressure are not typical causes of the manifestations of coronary artery disease.
Choice C rationale
Coronary arteries become more elastic causing the arteries to stretch as individuals age causing the heart not to receive enough oxygen. This is incorrect because the problem in coronary artery disease is not increased elasticity but rather the loss of elasticity and the buildup of plaque that narrows the arteries. As people age, the arteries tend to become less elastic, not more.
Choice D rationale
The heart and the coronary arteries weaken, leading to poor perfusion and resulting in angina. This is incorrect because the primary issue in coronary artery disease is the narrowing of the coronary arteries due to plaque buildup, not the weakening of the heart and arteries. While poor perfusion does result in angina, it is due to the narrowed arteries rather than weakened structures.
Correct Answer is B
Explanation
Choice A rationale
Doubling the dose of warfarin if a dose is missed is incorrect because it can lead to an increased risk of bleeding. Warfarin is an anticoagulant, and maintaining a consistent blood level is crucial to avoid complications. Doubling the dose can cause the blood to become too thin, leading to severe bleeding events.
Choice B rationale
Using an electric razor while on warfarin is correct because it helps prevent cuts and bleeding. Warfarin increases the risk of bleeding, and using an electric razor reduces the chance of nicks and cuts that can occur with a traditional razor.
Choice C rationale
Increasing fiber intake to reduce constipation is incorrect because warfarin does not typically cause constipation. Fiber intake is generally recommended for overall digestive health, but it is not specifically related to warfarin use.
Choice D rationale
Mild nosebleeds are not common during initial treatment with warfarin. Nosebleeds can indicate that the blood is too thin, which is a sign of over-anticoagulation and requires medical attention.
