Question 1 of 5
A patient has received an IV dose of adenosine, and almost immediately the heart monitor shows
Correct Answer: D
Rationale: Adenosine is a medication commonly used to treat certain types of irregular heartbeats, such as supraventricular tachycardia. One of the common side effects of adenosine administration is transient asystole or a brief pause in the electrical activity of the heart. This can cause the heart to stop beating momentarily, leading to a drop in blood pressure and a feeling of lightheadedness in the patient. Therefore, in this scenario where the heart monitor shows an immediate abnormality after adenosine administration, the nurse should prepare to administer cardiopulmonary resuscitation and be ready to intervene if the patient's heart rhythm deteriorates further. It is crucial to be proactive and prepared to respond quickly to any adverse effects of the medication to prevent potential harm to the patient. Regular monitoring should also continue to assess the patient's condition and response to treatment.
Question 2 of 5
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

Question 4 of 5
What patient could potentially take the drug Senna?
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.
Question 5 of 5
Propranolol is classified as having which of the following pharmacological actions?
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.
