The nurse is reviewing data of a client in acute heart failure who is receiving hydralazine IV push. Which is the therapeutic effect of this medication?

Relieve anxiety

Lower blood pressure

Anticoagulation

Control arrhythmia

Answer and Explanation

The Correct Answer is B

a. Relieve anxiety: Hydralazine is not indicated for the relief of anxiety. It is primarily used as an antihypertensive medication to lower blood pressure.

b. Lower blood pressure: Hydralazine is a vasodilator medication that works by relaxing and widening blood vessels, resulting in lower blood pressure. This is the therapeutic effect of hydralazine, particularly in the context of acute heart failure where reducing afterload can help improve cardiac output.

c. Anticoagulation: Hydralazine does not possess anticoagulant properties. It primarily affects blood pressure by dilating blood vessels, but it does not have direct anticoagulant effects.

d. Control arrhythmia: Hydralazine is not typically used to control arrhythmias. Its primary role is in lowering blood pressure through vasodilation.

Correct Answer is ["A","B","C","E"]

Explanation

a. Abdominal distension: Abdominal distension can occur in cases of severe digoxin toxicity due to its effects on gastrointestinal motility. Digoxin toxicity can lead to nausea, vomiting, and abdominal discomfort, which can contribute to abdominal distension. Therefore, abdominal distension is consistent with digoxin toxicity.

b. Digoxin level 4.1 ng/ml (0.8-2.0ng/ml): Digoxin levels above the therapeutic range (0.8-2.0 ng/ml) indicate digoxin toxicity. A level of 4.1 ng/ml is significantly higher than the therapeutic range, confirming digoxin toxicity.

c. Blurry vision: Blurry vision is a common symptom of digoxin toxicity. Visual disturbances, such as yellow or green halos around lights or changes in color vision, can occur due to digoxin's effects on the optic nerve. Therefore, blurry vision is consistent with digoxin toxicity.

d. Increased platelet level: Digoxin toxicity typically does not cause an increase in platelet levels. Instead, it can lead to thrombocytopenia (a decrease in platelet levels) due to its effects on bone marrow function. Therefore, increased platelet levels are not consistent with digoxin toxicity.

e. Arrhythmia: Digoxin toxicity can cause various cardiac arrhythmias, including atrial tachycardia, atrioventricular block, and ventricular tachycardia. Therefore, experiencing arrhythmias is consistent with digoxin toxicity.

A. Warfarin B. Enalapril C. Bumetanide D. Dobutamine

Correct Answer is D

Explanation

a. Warfarin: Warfarin is an anticoagulant medication used to prevent blood clot formation. While it is commonly prescribed for certain cardiac conditions such as atrial fibrillation or mechanical heart valves to prevent thromboembolic events, it does not directly improve the force of cardiac contraction. Therefore, warfarin is not the appropriate medication for improving cardiac contraction in a client with pulmonary edema.

b. Enalapril: Enalapril is an angiotensin-converting enzyme (ACE) inhibitor used to manage hypertension and heart failure. While ACE inhibitors can help reduce preload and afterload on the heart, leading to improved cardiac function over time, they do not directly improve the force of cardiac contraction acutely. Therefore, enalapril is not the appropriate medication for improving cardiac contraction in a client with pulmonary edema.

c. Bumetanide: Bumetanide is a loop diuretic medication used to promote diuresis and reduce fluid overload in conditions such as heart failure and pulmonary edema. While reducing fluid overload can indirectly improve cardiac function by reducing preload on the heart, loop diuretics do not directly improve the force of cardiac contraction.

d. Dobutamine: Dobutamine is a positive inotropic medication that directly stimulates beta-1 adrenergic receptors in the heart, leading to increased myocardial contractility (force of cardiac contraction) and improved cardiac output. It is commonly used in the treatment of acute heart failure, including pulmonary edema, to enhance cardiac function and reduce symptoms of congestion.
