The home health care nurse is conducting a home visit with an older adult client who has a history of coronary artery disease, hypertension, and heart failure. The client has a new prescription for furosemide 40 mg PO daily. Which statement by the client indicates a correct understanding of taking this new medication safely?
"I will notify my doctor if my urine output increases after a few doses."
"I will not eat my usual banana with my breakfast cereal in the morning."
"I will need to change positions slowly when going from laying down to sitting and then sitting to standing."
"I will take my furosemide with a full glass of water just before bed time."
The Correct Answer is C
A. "I will notify my doctor if my urine output increases after a few doses.": Diuresis is the intended pharmacological outcome for a patient with heart failure receiving loop diuretics. Increased urinary frequency and volume indicate that the medication is effectively reducing fluid overload. Reporting this expected finding would be an unnecessary use of clinical resources.
B. "I will not eat my usual banana with my breakfast cereal in the morning.": Furosemide promotes the excretion of potassium in the distal tubule and the loop of Henle. Bananas are a high-potassium food that helps prevent the development of hypokalemia during diuretic therapy. Restricting dietary potassium while taking a non-potassium-sparing diuretic increases the risk of cardiac arrhythmias.
C. "I will need to change positions slowly when going from laying down to sitting and then sitting to standing.": Rapid fluid volume reduction and vasodilation can lead to a significant drop in blood pressure upon standing. This orthostatic hypotension increases the risk of falls and syncope in older adult patients. Gradual transitions allow the body's baroreceptors to adjust and maintain adequate cerebral perfusion.
D. "I will take my furosemide with a full glass of water just before bed time.": Administering loop diuretics in the evening results in nocturia, which disrupts the patient's sleep cycle and increases fall risks at night. Medication should be taken in the morning to allow for peak diuresis during waking hours. Timing the dose correctly is essential for maintaining patient safety and quality of life.

Correct Answer is B
Explanation
A. Call the cardiologist: Contacting the specialist is necessary for definitive management but is not the most immediate nursing action. Delays in providing basic physiological support while waiting for a physician's response can lead to further myocardial damage. Initial stabilization must occur before coordinating the next level of specialized care.
B. Administer oxygen: Myocardial infarction involves a critical mismatch between oxygen supply and demand in the cardiac tissue. Providing supplemental oxygen increases the concentration of oxygen in the blood to help salvage ischemic myocardium and relieve dyspnea. This is a primary intervention to reduce the severity of the infarct and stabilize the patient.
C. Obtain vital signs: While baseline data is important for monitoring, the patient's immediate report of shortness of breath indicates an acute respiratory and circulatory crisis. Taking blood pressure and temperature does not actively treat the underlying hypoxia or chest pain. Interventions to improve oxygenation should take precedence over data collection during active ischemia.
D. Place the client in a supine position: Lying flat increases venous return and the workload of the heart, which can worsen both chest pain and shortness of breath. Patients in respiratory distress should be placed in a high-Fowler's position to maximize lung expansion and decrease cardiac strain. A supine position is physiologically detrimental during an acute coronary event.
Correct Answer is D
Explanation
A. Nitroglycerin: This vasodilator is used to treat anginal chest pain by reducing preload and dilating coronary arteries. It has no role in the management of atrial fibrillation, which is characterized by an irregularly irregular rhythm. Using a nitrate here would not address the underlying electrical disorganized activity in the atria.
B. Hydrochlorothiazide: As a thiazide diuretic, this medication is used primarily for the long-term management of hypertension and mild fluid retention. It does not possess any antiarrhythmic properties and would not be effective in controlling the ventricular rate. Diuretics are not the standard of care for treating an acute rhythm disturbance on a telemetry strip.
C. Atropine: This anticholinergic agent is indicated for the treatment of symptomatic bradycardia by increasing the heart rate. Atrial fibrillation often requires rate control to prevent tachycardia-induced cardiomyopathy rather than stimulation of a faster rate. Atropine could potentially worsen the clinical situation by causing a dangerously rapid ventricular response.
D. Warfarin: Atrial fibrillation causes blood to pool in the atria, which significantly increases the risk of mural thrombus formation and subsequent embolic stroke. Anticoagulation is a mandatory component of management to prevent these life-altering thromboembolic complications. Warfarin is a standard oral anticoagulant used to maintain a therapeutic INR in patients with this chronic dysrhythmia.
