A nurse is assisting with the collection of a bone marrow specimen from a preschooler. Which of the following actions should the nurse take?
Position the child sitting with their buttocks at the edge of the table.
Place the child in a 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.
The Correct Answer is B
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.

Correct Answer is C
Explanation
Choice A rationale:
Cleaning the infant's suture line with chlorhexidine solution is not indicated immediately after cleft lip repair. The primary concern in the immediate postoperative period is pain management and wound healing, and cleaning the suture line with chlorhexidine could potentially disrupt the healing process.
Choice B rationale:
Applying elbow immobilizers to the infant is not necessary after cleft lip repair. Elbow immobilizers are typically used in situations where there's a need to restrict arm movement, such as preventing a child from bending their arms after certain types of surgery. Cleft lip repair does not involve the arms, so this action is not relevant.
Choice C rationale:
Correct Choice. Offering the infant a pacifier with sucrose for pain relief is appropriate. Non-nutritive sucking, such as using a pacifier, has been shown to have pain-relieving effects in infants. Sucrose, a sweet solution, is often used in combination with non-nutritive sucking to further enhance pain relief during minor procedures or painful experiences. It provides comfort and distraction to the infant, helping to reduce their discomfort.
Choice D rationale:
Placing the infant in a prone position for sleeping is contraindicated after cleft lip repair. Placing an infant prone (on their stomach) for sleep increases the risk of sudden infant death syndrome (SIDS). The recommended sleep position for infants is supine (on their back) to ensure their safety.
Correct Answer is A
Explanation
Choice A rationale:
Maintaining oral rehydration therapy is a crucial nursing action when caring for a child with shigella, which is a bacterial infection that causes severe diarrhea. Oral rehydration therapy helps prevent dehydration and electrolyte imbalances caused by fluid loss from diarrhea. It involves giving the child oral rehydration solutions containing electrolytes and fluids to replace those lost through diarrhea.
Choice B rationale:
Providing a diet high in sodium is not recommended for a child with shigella. Shigella is associated with diarrhea and gastrointestinal symptoms, and a high-sodium diet can worsen fluid imbalances and dehydration.
Choice C rationale:
Shigella is a bacterial infection, not a viral infection, so administering antiviral medication would not be effective or appropriate. Antiviral medications are used to treat viral infections, not bacterial ones like shigella.
Choice D rationale:
Giving antidiarrheal agents every 4 hours is not recommended for a child with shigella. Antidiarrheal agents can slow down the gastrointestinal tract and inhibit the body's natural mechanism for expelling harmful substances, such as bacteria. It's important to allow the body to eliminate the bacteria and toxins causing the infection through diarrhea, while simultaneously providing rehydration support.
