A nurse is caring for a client who reports difficulty breathing during the administration of an intermittent IV bolus of nafcillin. After stopping the infusion and notifying the provider, the nurse should anticipate a prescription for which of the following medications?
Deferoxamine
Vitamin K
Epinephrine
Prednisone
The Correct Answer is C
A. Deferoxamine. Deferoxamine is a chelating agent used to treat iron overload or toxicity. It has no role in managing an acute allergic reaction or respiratory distress caused by nafcillin, a penicillin-type antibiotic.
B. Vitamin K. Vitamin K is used to reverse the effects of warfarin-induced anticoagulation and is not indicated for treating an allergic reaction. Anaphylaxis is not related to coagulation disturbances, making this an inappropriate intervention.
C. Epinephrine. Epinephrine is the first-line treatment for anaphylaxis, which can present with difficulty breathing, bronchospasm, and hypotension. It works by stimulating alpha- and beta-adrenergic receptors, leading to bronchodilation, increased cardiac output, and vasoconstriction to counteract severe allergic reactions. Immediate administration is necessary to prevent further airway compromise and circulatory collapse.
D. Prednisone. Prednisone is a corticosteroid used to reduce inflammation and prevent delayed allergic reactions. While it may be prescribed as part of long-term management, it does not provide the rapid bronchodilation and vasoconstriction needed for emergency treatment of anaphylaxis.

Correct Answer is A
Explanation
A. Cover the administration area with plastic wrap. After applying nitroglycerin ointment, the area should be covered with plastic wrap or a transparent dressing to prevent evaporation and ensure proper absorption through the skin. This also helps prevent the medication from accidentally transferring to another person or clothing.
B. Massage the ointment into the skin. Nitroglycerin ointment should not be massaged into the skin, as this can cause rapid absorption and lead to hypotension and dizziness due to vasodilation. Instead, it should be applied as a thin, even layer and covered with a dressing.
C. Spread the ointment in a 10 cm² (4 in²) area. The correct application method involves measuring the exact prescribed amount (e.g., using the applicator paper) and applying it in a thin layer. The area of application may vary based on the dosage, but the focus should be on accurate measurement, not a specific area size.
D. Apply the ointment in a thick layer. A thick application is unnecessary and could increase absorption too quickly, leading to side effects such as headache, dizziness, and hypotension. Instead, a measured dose should be spread thinly and evenly onto clean, dry skin.
Correct Answer is C
Explanation
A. The client had a local reaction from a previous immunization. A mild local reaction, such as redness or swelling at the injection site, is not a contraindication to receiving the MMR vaccine. These reactions are common and typically resolve without complications. Only severe allergic reactions, such as anaphylaxis, would warrant withholding the vaccine.
B. The client reports having diarrhea this morning. Mild illnesses, such as diarrhea or the common cold, do not contraindicate vaccination. The MMR vaccine can be safely administered as long as the client does not have a moderate to severe illness with fever. Delaying immunization due to minor illnesses could lead to unnecessary gaps in vaccine coverage.
C. The client is at 9 weeks of gestation. The MMR vaccine is a live attenuated vaccine and is contraindicated during pregnancy due to the theoretical risk of fetal harm. Pregnant individuals should wait until after delivery to receive the vaccine. If a client of childbearing age is vaccinated, they should be advised to avoid pregnancy for at least 4 weeks following immunization to reduce the risk of congenital rubella syndrome.
D. The client reports an allergy to penicillin. A penicillin allergy is not a contraindication for the MMR vaccine. The MMR vaccine does not contain penicillin or related antibiotics. Severe allergic reactions to vaccine components, such as neomycin or gelatin, would be more relevant contraindications. Clients with a penicillin allergy can safely receive the MMR vaccine without concern.
