A nurse in a clinic is assessing a 60-year-old client at an annual examination. The client asks the nurse about receiving a shingles vaccination. The nurse should identify that which of the following medications prescribed to the client is a contraindication for receiving this vaccine?

A. Verapamil: Verapamil is a calcium channel blocker primarily used to treat supraventricular

tachycardias, not ventricular dysrhythmias. It is not typically used for life-threatening ventricular dysrhythmias.
B. Digoxin: Digoxin is a cardiac glycoside used primarily for atrial fibrillation and heart failure, not ventricular dysrhythmias. It is not typically used for life-threatening ventricular
dysrhythmias.

C. Dopamine: Dopamine is a sympathomimetic medication used for hemodynamic support in hypotension and shock. While it may be used in some cases of unstable bradycardia, it is not the first-line medication for life-threatening ventricular dysrhythmias.
D. Amiodarone: Amiodarone is an antiarrhythmic medication used for the treatment of various ventricular and supraventricular dysrhythmias, including life-threatening ventricular
dysrhythmias such as ventricular tachycardia and ventricular fibrillation. It is often used as a first-line medication for these conditions due to its efficacy and safety profile. Therefore, the nurse should anticipate administering amiodarone for the client's life-threatening ventricular dysrhythmia.

A. Constipation: Constipation is not a commonly reported adverse effect of clopidogrel.

Therefore, it is not necessary to instruct the client to monitor and report constipation as an adverse effect.
B. Weight loss: Weight loss is not a commonly reported adverse effect of clopidogrel. Therefore, it is not necessary to instruct the client to monitor and report weight loss as an adverse effect.
C. Bruising: Clopidogrel is an antiplatelet medication that inhibits platelet aggregation.

Therefore, one of the potential adverse effects is an increased risk of bleeding, which can

manifest as easy bruising or prolonged bleeding from minor injuries. Instructing the client to monitor and report bruising is important for early detection of bleeding complications.
D. Blurred vision: Blurred vision is not a commonly reported adverse effect of clopidogrel.

Therefore, it is not necessary to instruct the client to monitor and report blurred vision as an adverse effect.
