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. 0.45% sodium chloride: 0.45% sodium chloride solution, also known as half-normal saline, is a hypotonic solution used for rehydration and maintenance fluid therapy. However, in cases of
major burns where there is a significant loss of fluid and electrolytes, isotonic solutions are generally preferred.
B. Lactated Ringer's: Lactated Ringer's solution is an isotonic crystalloid solution that closely resembles the electrolyte composition of extracellular fluid. It is commonly used for fluid resuscitation in clients with major burns to replace lost fluids and electrolytes and restore
intravascular volume.

C. Dextrose 5% in water: Dextrose 5% in water is a hypotonic solution used primarily for hydration in clients with normal electrolyte levels or as a vehicle for administering medications.
It is not typically used for fluid resuscitation in clients with major burns, as it does not adequately replace lost electrolytes.
D. Dextrose 5% in 0.45% sodium chloride: This solution combines dextrose 5% and 0.45% sodium chloride and is used for maintenance fluid therapy and mild dehydration. However, in cases of major burns where there is significant fluid and electrolyte loss, isotonic solutions like lactated Ringer's or normal saline are preferred for fluid resuscitation.

A. Bradycardia: Amiodarone, an antiarrhythmic medication, can cause bradycardia as an adverse effect due to its negative chronotropic effects on the heart's electrical conduction system. Bradycardia is a common adverse effect of amiodarone and requires monitoring during therapy.
B. Fever: Fever is not a typical adverse effect of amiodarone. If a client develops a fever while taking amiodarone, other potential causes should be investigated.
C. Hypertension: Hypertension is not a typical adverse effect of amiodarone. Amiodarone is more commonly associated with bradycardia and hypotension.
D. Bradypnea: Bradypnea, or slow respiratory rate, is not a typical adverse effect of amiodarone.

Respiratory adverse effects of amiodarone are more commonly related to pulmonary toxicity, such as pulmonary fibrosis or pneumonitis.
