Question 1 of 5
When starting a patient on antidysrhythmic therapy, the nurse will remember that which problem is a potential adverse effect of any antidysrhythmic drug?
Correct Answer: D
Rationale: While it may seem counterintuitive that starting a patient on antidysrhythmic therapy could potentially cause dysrhythmias, it is important to remember that antidysrhythmic drugs can have proarrhythmic effects. Proarrhythmia refers to the development of new or more severe dysrhythmias as a result of the medication intended to treat dysrhythmias. This can occur due to various mechanisms, such as altering the electrical conduction system of the heart or disrupting the normal rhythm. Therefore, dysrhythmias are a potential adverse effect that the nurse should monitor for when initiating antidysrhythmic therapy in a patient. It is crucial for the healthcare team to closely monitor the patient's cardiac rhythm and adjust the medication regimen as needed to minimize the risk of proarrhythmia.

Question 3 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 4 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.
Question 5 of 5
A nurse is about to administer Propanolol to a patient. The nurse takes the patient's apical pulse and documents it as 58 bmp. How should the nurse continue?
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.
