A nurse is assisting in the plan of care for a client who has a suspected myocardial infarction. Which of the following medications should the nurse plan to administer first?
Morphine
Nitroglycerin
Aspirin
Oxygen
The Correct Answer is D
Choice A reason : Morphine is an opioid analgesic used to relieve severe pain and can be administered to patients with myocardial infarction to alleviate chest pain and anxiety. However, it is not the first medication given as it does not address the underlying cause of the myocardial infarction, which is the formation of a blood clot in the coronary arteries.
Choice B reason : Nitroglycerin is a nitrate that helps to dilate blood vessels and improve blood flow. It can be used to relieve chest pain in myocardial infarction, but similar to morphine, it is not the initial medication of choice. The priority is to prevent further blood clotting.
Choice C reason : Administered as soon as possible to inhibit platelet aggregation and reduce clot progression.
Choice D reason : When a myocardial infarction (MI) is suspected, the priority is to address tissue hypoxia and ensure adequate oxygenation to minimize myocardial damage. Administering oxygen helps increase oxygen availability to the ischemic heart tissue, reducing further damage.

Correct Answer is C
Explanation
Choice A reason : Setting a goal body weight within 25% of the ideal body weight can be misleading. The ideal body weight should be determined based on body mass index (BMI), considering the individual's height and weight. A BMI of 18.5 to 24.9 is considered normal.
Choice B reason : This is a general guideline for alcohol consumption, but for individuals with hypertension, it is often recommended to limit alcohol intake even further to help manage blood pressure
Choice C reason : This is a key recommendation for managing hypertension. Reducing sodium intake helps lower blood pressure and is a widely accepted guideline
Choice D reason : Monitoring potassium levels is crucial when taking thiazide diuretics because these medications can decrease potassium levels in the blood, leading to hypokalemia.
Correct Answer is C
Explanation
Choice A reason : The statement that warfarin dissolves clots in the bloodstream is incorrect. Warfarin does not dissolve existing clots. Instead, it is an anticoagulant that works by decreasing the production of certain clotting factors in the blood, which helps prevent the formation of new clots.
Choice B reason : This statement is not accurate regarding the action of warfarin. Warfarin does not affect the electrical impulses of the heart. Medications that slow the response of the ventricles to fast atrial impulses are typically antiarrhythmic drugs, not anticoagulants like warfarin.
Choice C reason : This is the correct statement. Warfarin is prescribed for clients with atrial fibrillation to reduce the risk of stroke. Atrial fibrillation increases the risk of forming blood clots in the heart, which can then travel to the brain, causing a stroke. Warfarin's anticoagulant effect helps to prevent these clots from forming.
Choice D reason : Warfarin does not help maintain a normal heart rhythm. It is not an antiarrhythmic drug but an anticoagulant. The purpose of warfarin in atrial fibrillation is to prevent stroke by reducing the risk of clot formation, not to correct the heart rhythm.
