The nurse is teaching a client with atrial fibrillation about the need to begin long-term anticoagulant therapy. Which explanation should the nurse use to best describe the reasoning for this therapy?

"Because of the dysrhythmia, blood backs up in the legs and puts you at risk for blood clots."

"Because the atria are quivering, blood flows sluggishly through them, and clots can form along the heart wall, which then could loosen and travel to the lungs or brain."

"The medications that you are taking cause blood clots as a side effect so you need this medication to prevent them."

Answer and Explanation

The Correct Answer is B

Choice A reason: The statement "Because of the dysrhythmia, blood backs up in the legs and puts you at risk for blood clots" is incorrect. Atrial fibrillation primarily causes blood to pool in the atria, not the legs.

Choice B reason: The statement "Because the atria are quivering, blood flows sluggishly through them, and clots can form along the heart wall, which then could loosen and travel to the lungs or brain" accurately explains the risk of clot formation in atrial fibrillation and the importance of anticoagulant therapy to prevent strokes and other complications.

Choice C reason: The statement "The medications that you are taking cause blood clots as a side effect so you need this medication to prevent them" is incorrect. Anticoagulant therapy in atrial fibrillation is used to prevent clot formation due to the arrhythmia itself, not as a counteraction to the side effects of other medications.

Correct Answer is C

Explanation

Choice A reason: Mild headaches are not typically associated with increased intraocular pressure. While headaches can accompany eye conditions, they are not as common or specific as severe eye pain in this context.

Choice B reason: Cloudiness that worsens at night could be related to cataracts or other eye conditions but is not a specific manifestation of increased intraocular pressure. Severe eye pain is a more direct indicator of conditions like acute angle-closure glaucoma.

Choice C reason: Severe eye pain is a significant clinical manifestation of increased intraocular pressure, such as in acute angle-closure glaucoma. This condition can lead to sudden, severe eye pain due to the rapid rise in intraocular pressure, which can damage the optic nerve if not treated promptly.

Choice D reason: Mild eye pain may occur in various minor eye conditions but is not as indicative of serious issues like increased intraocular pressure. Severe eye pain is more concerning and requires immediate assessment and intervention.

A. Cigarettes or tobacco smoke B. Air pollution C. Any physical activity D. Certain cough products

Correct Answer is ["A","B","D"]

Explanation

Choice A reason: Cigarette or tobacco smoke is a major trigger for asthma attacks. Inhaling smoke irritates the airways, leading to inflammation and bronchoconstriction, making it harder for asthmatic individuals to breathe.

Choice B reason: Air pollution, including smog, industrial emissions, and vehicle exhaust, can exacerbate asthma symptoms. Pollutants in the air can trigger airway inflammation and constriction, leading to asthma attacks.

Choice C reason: Physical activity is not a common trigger for moderate persistent asthma if managed properly. Regular exercise is generally encouraged for overall health and can help improve lung function. However, clients should use their prescribed inhaler and follow their asthma action plan to manage exercise-induced asthma symptoms.

Choice D reason: Certain cough products, especially those containing ingredients like menthol or chemicals, can irritate the airways and trigger asthma symptoms. It's important for clients with asthma to avoid using over-the-counter cough products without consulting their healthcare provider.
