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.

Correct Answer is B

Explanation

Infusion reaction is a common adverse effect of amphotericin B that occurs within 1 to 3 hours of starting the infusion and causes symptoms such as fever, chills, headache, nausea, vomiting, and hypotension.

A is incorrect because anaphylaxis is a severe allergic reaction that causes symptoms such as urticaria, angioedema, bronchospasm, and shock.

C is incorrect because nephrotoxicity is another adverse effect of amphotericin B that causes renal impairment and electrolyte imbalances.

D is incorrect because ototoxicity is an adverse effect of some antibiotics such as gentamicin and vancomycin that causes hearing loss and tinnitus.

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

Correct Answer is C

Explanation

Answer: C. Intravenous injection is the fastest route for administering diphenhydramine in a severe allergic reaction because it provides immediate onset of action and avoids the first-pass metabolism in the liver.

A and B are incorrect because intramuscular and subcutaneous injections have slower absorption rates than intravenous injection and may not provide adequate relief in an emergency situation.

D is incorrect because oral administration of diphenhydramine has the slowest absorption rate and onset of action and is subject to first-pass metabolism in the liver.
