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 D
Explanation
A. Postoperative pain typically resolves after a laparoscopic cholecystectomy since the surgery removes the gallbladder
B. While positioning during surgery can cause discomfort, isolated right shoulder pain is more commonly attributed to the diaphragmatic irritation from residual nitrous oxide in the abdomen.
C. Nitrous dioxide used during laparoscopic procedures is not associated with referred pain to the right shoulder. The pain is due to carbon dioxide gas used during the procedure resulting in the irritation of the diaphragm.
D. This pain is often due to the carbon dioxide used to inflate the abdomen during surgery, which can irritate the diaphragm and refer pain to the shoulder. Ambulation helps to absorb the gas more quickly.
Correct Answer is C
Explanation
A. Daily weight monitoring is important for assessing fluid status but may not provide real-time information about fluid balance changes.
B. Vital signs are important for overall assessment but may not specifically address the nursing diagnosis of Excess Fluid Volume unless there are significant changes indicative of fluid overload or dehydration.
C. Monitoring intake and output provides direct information about fluid balance and renal function, helping to identify trends and assess the effectiveness of interventions aimed at managing fluid volume.
D. Skin turgor assessment is useful for evaluating hydration status but may not provide comprehensive data on fluid volume excess alone.
