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

B. Ibuprofen is contraindicated in patients with low platelet counts due to the risk of bleeding. Therefore, administering ibuprofen would exacerbate the risk of bleeding in this patient.
C. Invasive procedures like rectal temperature measurements should be avoided in patients with low platelet counts due to the risk of bleeding. Thus, this intervention increases the risk of harm to the patient.
D. Patients with low platelet counts are at risk for bleeding, including gastrointestinal bleeding. Administering a stool softener can help prevent straining during bowel movements, reducing the risk of bleeding and promoting patient comfort and safety.
