A patient is receiving digoxin 0.25 mg/day as part of treatment for HF. The nurse assesses the patient before medication administration. Which assessment finding would be of most concern?

Correct Answer: C

Rationale: The most concerning assessment finding for a patient receiving digoxin is a low serum potassium level (Option C). Hypokalemia increases the risk of digoxin toxicity, as low potassium levels enhance the effect of digoxin on the myocardium, leading to an increased risk of serious dysrhythmias. It is important to address and correct hypokalemia promptly to prevent potential adverse effects of digoxin. An apical heart rate of 58 beats/min (Option A) could be an expected finding for a patient on digoxin, and ankle edema +1 bilaterally (Option B) is a common symptom of heart failure. A serum digoxin level of 0.8 ng/mL (Option D) is within the therapeutic range for digoxin and is not concerning in the absence of other symptoms. Therefore, managing the low serum potassium level is of utmost

Correct Answer: B

Rationale: Senna is a stimulant laxative commonly used to treat constipation. It works by irritating the lining of the intestines, thereby promoting bowel movements. Patients who have not passed stool in several days may benefit from taking Senna to help relieve constipation and promote regular bowel movements. Patients with conditions such as eating disorders, anal fissures, or hemorrhoids may also benefit from stool softeners or other laxatives, but Senna specifically targets constipation due to its stimulant properties. It is essential to consult with a healthcare provider before starting any laxative therapy to determine the appropriate treatment plan for each individual.

Correct Answer: A

Rationale: Propranolol is a medication that belongs to the class of drugs known as beta blockers. Beta blockers work by blocking the effects of the stress hormones adrenaline and noradrenaline on the beta receptors in the body. By blocking these receptors, propranolol helps to reduce heart rate, blood pressure, and the workload on the heart, making it effective in the treatment of conditions such as high blood pressure, angina, and certain heart rhythm disorders.

Correct Answer: D

Rationale: The nurse should withhold administration of the medication and notify the physician. The apical pulse of 58 bpm is below the normal range (60-100 bpm for adults), and propranolol is a beta-blocker that can further decrease the heart rate. Administering propranolol at this low heart rate may cause bradycardia (excessively slow heart rate) which can lead to serious complications. It is important to inform the physician of the low heart rate so that appropriate action or further assessment can be taken before administering the medication.

Correct Answer: A

Rationale: Propranolol belongs to the class of drugs known as beta blockers. Beta blockers work by blocking the effects of adrenaline on beta receptors in the body, resulting in decreased heart rate, blood pressure, and cardiac output. Propranolol is commonly used to treat conditions such as hypertension, angina, and certain cardiac arrhythmias. It is specifically a non-selective beta blocker, meaning it blocks both beta-1 and beta-2 receptors.
