A patient who has just been admitted with pulmonary edema is scheduled to receive the following medications. Which medication would the nurse question before giving?.

Digoxin (Lanoxin) 0.125 mg.

Captopril (Capoten) 25 mg.

Furosemide (Lasix) 60 mg.

Carvedilol (Coreg) 3.125 mg. .

Answer and Explanation

The Correct Answer is A

Choice A rationale:

Digoxin is used to treat heart failure and atrial fibrillation, but it doesn’t directly address the fluid accumulation in the lungs caused by pulmonary edema.

Choice B rationale:

Captopril, an ACE inhibitor, can help reduce fluid buildup and is typically beneficial for patients with pulmonary edema.

Choice C rationale:

Furosemide is a diuretic that helps remove excess fluid from the body, making it a key medication for treating pulmonary edema.

Choice D rationale:

Carvedilol, a beta blocker, can be used to treat heart failure and hypertension, conditions that can contribute to pulmonary edema.

So, the correct answer is A, after analyzing all choices.

Correct Answer is A

Explanation

Choice A rationale:

Cardiac-specific troponin is a protein that is released into the bloodstream when there is damage to the heart muscle, such as during an acute myocardial infarction (AMI). It is considered the most specific marker for AMI because it is found only in heart muscle. The normal range for troponin I is between 0 and 0.04 ng/mL2.

Choice B rationale:

Myoglobin is a protein found in heart and skeletal muscles. While it can be elevated in AMI, it is not as specific as troponin because it is also found in skeletal muscles. The normal levels of myoglobin are 25 to 72 ng/mL4.

Choice C rationale:

Homocysteine is an amino acid in the blood, and high levels can increase the risk of heart disease. However, it is not specific for AMI5. The normal range of homocysteine levels are less than 15 micromoles per liter.

Choice D rationale:

C-reactive protein (CRP) is a marker of inflammation in the body and can be elevated in various conditions, including heart disease. However, it is not specific for AMI6. The normal CRP level is less than 0.9 milligrams per deciliter.

So, the correct answer is A, after analyzing all choices.

A. Elevated troponin. B. Q Waves on ECG. C. Bilateral crackles. D. Hyperglycemia.

Correct Answer is A

Explanation

Choice A rationale:

Elevated troponin is a sign of heart damage, which could be caused by a heart attack or other stresses on the heart. This is a critical finding that needs immediate attention.

Choice B rationale:

Q waves on an ECG can indicate a previous heart attack or myocardial infarction. However, they can also be a normal variant, meaning they are a harmless variation in the electrical activity of the heart.

Choice C rationale:

Bilateral crackles in the lungs can indicate mucus or fluid in the base of the lungs, often associated with conditions like pneumonia, heart failure, or bronchitis.

Choice D rationale:

Hyperglycemia, or high blood glucose, can be a sign of diabetes. If untreated, it can lead to serious complications like ketoacidosis.

So, the correct answer is Choice A, after analyzing all choices.
