. A nurse is assisting with the collection of a bone marrow specimen from a preschooler. Which of the following actions should the nurse take?
Place the child in prone position to expose the posterior iliac crest.
Position the child side-lying to expose the vertebrae.
Place the child supine with legs flexed outward into a frog-like position.
Position the child sitting with their buttocks at the edge of the table.
The Correct Answer is A
A. The posterior iliac crest is the typical site for bone marrow aspiration in children. Placing the child in the prone position allows for proper access to the site while ensuring the child remains safe and stable during the procedure.
B. Positioning the child side-lying would expose the vertebrae but is not an optimal position for accessing the iliac crest for bone marrow aspiration.
C. The frog-like position (supine with legs flexed outward) is not an appropriate position for a bone marrow aspiration, as it does not provide the best access to the iliac crest or posterior iliac crest.
D. Sitting with the buttocks at the edge of the table would not adequately expose the posterior iliac crest, making it unsuitable for bone marrow aspiration.

Correct Answer is C
Explanation
A. Selecting a catheter that fits snugly is important for proper suctioning, but it is more important to ensure the catheter is the correct size for the infant’s tracheostomy tube and airway.
B. Instilling saline prior to suctioning is generally not recommended unless specified by the healthcare provider, as it can increase the risk of aspiration and discomfort.
C. Suctioning should be done in short 3 to 4 second increments to avoid injury to the airway and to minimize the infant’s distress. Prolonged suctioning can cause hypoxia and trauma to the mucosa.
D. Suctioning for infants with tracheostomies requires sterile technique to prevent infection, not clean technique.
Correct Answer is B
Explanation
A. Applying calamine lotion is helpful for symptom relief but does not remove the poison ivy oil from the skin.
B. Flushing the affected area with cold, running water immediately after exposure helps to remove the poison ivy oil (urushiol) from the skin, which is crucial in preventing or reducing the severity of the rash.
C. While an oatmeal bath can help soothe itching, it is not the priority action in the acute stage of exposure.
D. Administering an oral corticosteroid may be necessary if the rash is severe, but flushing the area with water should be the first step in preventing further reaction.
