A nurse is teaching a client who has a history of anaphylaxis about the use of an epinephrine auto-injector. Which of the following instructions should the nurse include in the teaching?

Inject the medication into the deltoid muscle.

Hold the device at a 90-degree angle to the thigh.

Massage the injection site for 10 minutes after administration.

Repeat the injection after 5 minutes if symptoms persist.

Answer and Explanation

The Correct Answer is B

Holding the device at a 90-degree angle to the thigh ensures proper penetration and delivery of the medication into the vastus lateralis muscle.

A is incorrect because injecting the medication into the deltoid muscle may not provide adequate absorption and onset of action.

C is incorrect because massaging the injection site may increase the risk of bleeding and bruising and may decrease the absorption of the medication.

D is incorrect because repeating the injection after 5 minutes may cause overdose and adverse effects such as hypertension, tachycardia, arrhythmias, and myocardial ischemia.

A. Intramuscular B. Subcutaneous C. Intravenous D. Oral

Correct Answer is A

Explanation

Intramuscular injection is the preferred route for administering epinephrine in anaphylaxis because it provides rapid absorption and onset of action.

B is incorrect because subcutaneous injection has a slower absorption rate than intramuscular injection and may not provide adequate relief in an emergency situation.

C is incorrect because intravenous injection of epinephrine can cause severe adverse effects such as cardiac arrhythmias and hypertension and should be reserved for life-threatening situations when other routes are ineffective.

D is incorrect because oral administration of epinephrine is ineffective due to extensive first-pass metabolism in the liver.
