A nurse is preparing to administer the measles, mumps, and rubella (MMR) vaccine to an adolescent. Which of the following should the nurse identify as a contraindication to administering this vaccine?

Choice A rationale:
Administer two puffs of albuterol. This is the correct answer because albuterol is a bronchodilator that helps to relieve acute asthma symptoms by opening up the airways. In a child experiencing difficulty breathing due to asthma, prompt administration of albuterol can help alleviate the symptoms and improve breathing.
Choice B rationale:
Place the child in the supine position. Placing the child in the supine position can further compromise their breathing, especially in a situation of asthma exacerbation. This position can restrict the airways and make breathing more difficult, so it is not an appropriate action.
Choice C rationale:
Encourage the use of a flutter mucus clearance device. While mucus clearance devices can be helpful for individuals with chronic respiratory conditions, such as cystic fibrosis, it is not the priority action for a child experiencing acute asthma symptoms. The immediate focus should be on relieving the airway constriction and addressing the breathing difficulty.
Choice D rationale:
Instruct the child to perform controlled breathing exercises. Controlled breathing exercises might be useful for anxiety and panic management, but in an acute asthma episode, the child's primary need is to open up the airways and improve breathing. Albuterol administration takes precedence over breathing exercises in this situation.

Choice A rationale:
Urticaria, commonly known as hives, is a skin rash characterized by raised, red, and itchy welts that can vary in size and shape. It is a classic manifestation of an allergic reaction. Allergic reactions can occur in response to medications like clindamycin. Urticaria is a result of histamine release and can range from mild to severe, with itching being a prominent symptom. The appearance of urticaria in a child taking clindamycin suggests a potential allergic reaction to the medication.
Choice B rationale:
Conjunctivitis, or pink eye, is inflammation of the conjunctiva, the clear membrane that covers the white part of the eye and lines the inner surface of the eyelids. While conjunctivitis can be associated with allergies, it is not a typical sign of an allergic reaction to clindamycin. Conjunctivitis is more commonly associated with eye irritation, redness, and discharge.
Choice C rationale:
A temperature of 38°C (100.4°F) alone is not a definitive sign of an allergic reaction to medication. Fever can be caused by a variety of factors, including infections, inflammatory processes, and other non-allergic reactions. While fever can be a symptom of an allergic reaction in some cases, it is not as specific as urticaria in indicating an allergic response.
Choice D rationale:
Cool extremities are not a classic sign of an allergic reaction to medication. Allergic reactions typically involve skin manifestations like hives, itching, and redness. Cool extremities might suggest poor peripheral circulation or decreased blood flow to the extremities, but they are not directly indicative of an allergic reaction to clindamycin.
