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:
Positioning the child sitting with their buttocks at the edge of the table is not appropriate for collecting a bone marrow specimen from a preschooler. This position does not provide adequate access to the bone marrow aspiration site and may lead to discomfort for the child.
Choice B rationale:
Placing the child in a prone position (lying face down) is suitable for collecting a bone marrow specimen from a preschooler. This position exposes the posterior iliac crest, which is a common site for bone marrow aspiration. It allows for easier access to the bone marrow and reduces the risk of injury.
Choice C rationale:
Positioning the child side-lying to expose the vertebrae is not the recommended position for bone marrow aspiration. The iliac crest, not the vertebrae, is the usual site for this procedure in children. Placing the child in a side-lying position would make it difficult to access the appropriate site.
Choice D rationale:
Placing the child supine with legs flexed outward into a frog-like position is suitable for collecting a bone marrow specimen. This position provides access to the iliac crest while allowing for better immobilization of the child. It also ensures the child's safety and comfort during the procedure.

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.
