The nurse is teaching a patient about digoxin. The nurse would evaluate the patient as understanding the teaching if the patient made which of these statements? Select all that apply.
The resting heart rate increases when digoxin is taken."
"Digoxin raises blood pressure."
"Digoxin slows the heart rate."
The force of heart contractions is increased with digoxin."
"Digoxin decreases ectopic beats."
Correct Answer : C,D,E
A. Digoxin typically decreases the heart rate by increasing vagal tone and reducing conduction through the atrioventricular node.
B. Digoxin may have minimal effects on blood pressure, primarily by improving cardiac output in patients with heart failure, but its primary action is on cardiac contractility and rhythm.
C. Digoxin has a negative chronotropic effect, meaning it slows the heart rate by increasing parasympathetic tone and decreasing conduction through the atrioventricular node.
D. Digoxin has a positive inotropic effect, meaning it increases the force of cardiac contractions, which can be beneficial in patients with heart failure.
E. Digoxin can suppress ectopic beats (abnormal heart rhythms originating outside the sinoatrial node) by slowing conduction through the atrioventricular node and enhancing vagal tone

Explanation
Elevated BUN and creatinine levels are common indicators of impaired kidney function, which can be seen in chronic kidney disease (CKD) and glomerulonephritis. Flank pain is often associated with UTIs but can also occur in glomerulonephritis. Decreased RBCs (red blood cells) can be a sign of glomerulonephritis due to the loss of blood cells in the urine. Fever is typically associated with infection, making it more indicative of a UTI.
Peripheral edema is is most commonly associated with CKD and glomerulonephritis due to the retention of fluids and sodium. Hypertension is a common finding in CKD and can also be seen in glomerulonephritis.
Correct Answer is B
Explanation
A. A negative waveform indicates a downward deflection from the baseline on an ECG tracing, which may correspond to electrical activity such as depolarization or repolarization of cardiac chambers.
B. An isoelectric line represents the baseline on an ECG tracing when there is no net electrical activity occurring in the heart. It appears flat and represents a period of electrical silence.
C. A downward deflection on an ECG tracing refers to a negative waveform, as mentioned above.
D. A positive waveform on an ECG tracing indicates an upward deflection from the baseline, representing electrical activity such as depolarization or repolarization.
