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

Correct Answer is B
Explanation
A. While controlling carbohydrate intake may be beneficial for managing blood glucose levels in some cases, it is not a primary dietary concern for chronic kidney disease.
B. Patients with chronic kidney disease often need to limit potassium intake because the kidneys may have difficulty excreting excess potassium, leading to hyperkalemia.
C. While protein restriction may be necessary in advanced stages of chronic kidney disease to reduce the workload on the kidneys, complete elimination of protein is not recommended.
D. Sodium restriction is often recommended for patients with chronic kidney disease to help control blood pressure and fluid balance.
Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"B"}
Explanation
Bleeding: The client's platelet count has dropped from 160,000/mm³ to 100,000/mm³, which is below the normal range (150,000 to 400,000/mm³). Platelets are essential for blood clotting, and a low count increases the risk of bleeding. Additionally, the prolonged PT (13.5 seconds) and elevated INR (2.2) further indicate a tendency toward bleeding.
Infection: The client's WBC count remains elevated at 15,500/mm³, which can be indicative of ongoing infection or inflammation. Patients with acute leukemia often have dysfunctional white blood cells, which impairs their ability to fight infections effectively.
