A nurse is assisting with teaching a group of newly licensed nurses about medication administration.
The nurse should include that which of the following medications is administered using the Z-track method?

Vitamin B12.

Folic acid.

Epoetin alfa.

Iron dextran.

Answer and Explanation

The Correct Answer is D

Choice A rationale

Vitamin B12 is administered intramuscularly but does not require the Z-track method as it does not irritate subcutaneous tissues. The Z-track method is reserved for drugs causing tissue staining or irritation.

Choice B rationale

Folic acid is typically given orally or intravenously and does not necessitate the Z-track method. It is well-tolerated by subcutaneous tissues and does not cause irritation.

Choice C rationale

Epoetin alfa is administered subcutaneously or intravenously without requiring the Z-track method. It is used to stimulate red blood cell production and does not stain or irritate tissues.

Choice D rationale

Iron dextran requires the Z-track method due to its potential to stain and irritate subcutaneous tissues. This method prevents leakage into surrounding tissue, ensuring proper drug absorption. .

Correct Answer is C,A,B,D

Explanation

Choice Crationale

Hand hygiene prevents introducing pathogens during the procedure, reducing the risk of infection at the venipuncture site.

Choice Arationale

Removing the dressing and tape exposes the IV site for catheter removal. Proper technique minimizes tissue trauma and discomfort.

Choice Brationale

Withdrawing the catheter removes the IV device. It is performed gently to avoid complications like vein damage or retained fragments.

Choice D rationale

Applying pressure with sterile gauze prevents bleeding by promoting hemostasis at the venipuncture site.

A. Replace wet clothing with warmed blankets. B. Use an axillary thermometer to monitor the client's temperature. C. Administer an antihypertensive medication. D. Assist the client to perform range-of-motion exercises.

Correct Answer is A

Explanation

Choice A rationale

Wet clothing exacerbates hypothermia by promoting heat loss through convection and evaporation. Replacing them with warmed blankets initiates passive rewarming, critical to restore normal body temperature (36.5°C to 37.5°C). Maintaining a warm environment minimizes shivering-induced metabolic demands and improves thermal regulation post-rescue.

Choice B rationale

Axillary thermometers measure skin temperature, often inaccurate in hypothermia where core temperature is needed. Core measurements via rectal or esophageal probes provide reliable readings, guiding rewarming interventions and severity classification, crucial for life-threatening hypothermia management.

Choice C rationale

Antihypertensives lower blood pressure and are inappropriate in hypothermia-related bradycardia or hypotension. Hypothermia-induced vasoconstriction maintains critical perfusion; medication interruption can worsen cardiovascular instability and reduce survival chances. Warmth stabilization precedes pharmacological actions.

Choice D rationale

Range-of-motion exercises increase metabolic rate but are not appropriate during hypothermia recovery. Muscular activity elevates oxygen demand, aggravating hypothermia risks such as arrhythmias. Passive warming supersedes these efforts until the client reaches normothermia and stability.
