The healthcare provider (HCP) prescribes 0.9% normal saline 500 mL IV bolus to be infused over 30 minutes. How many mL/hour should the nurse set the infusion pump?

(Round off to the nearest whole number)

Choice A reason: Listing the procedural steps is helpful but does not demonstrate practical competence.

Choice B reason: Reviewing glycosylated hemoglobin levels provides information about long-term glucose control but does not directly assess the technique.

Choice C reason: Adolescents (ages 12–18) are in a developmental stage where peer validation is a powerful motivator. By demonstratingto a peer, the adolescent is forced to internalize the steps well enough to explain them. This confirms a higher level of mastery than simply repeating steps back to a dynamic authority figure like a nurse.In a testing environment, "demonstrating the technique" to a peer does not mean the nurse allows the adolescent to actually stick a needle into another person. It means the adolescent acts out the procedure (perhaps using a practice pad, an orange, or a needleless syringe) while explaining the steps to the peer. The nurse is the observer in this scenario. The adolescent is the "teacher," and the peer is the "audience."

Choice D reason: Describing the level of comfort provides insight into his confidence but not necessarily his technical competence.

Choice A reason: Holding the infant with head and shoulders slightly elevated helps prevent aspiration during feeding.

Choice B reason: Using the syringe plunger to push formula can increase the risk of aspiration and is not recommended.

Choice C reason: Microwaving formula can create hot spots and is not a safe method to warm formula.

Choice D reason: Measuring and discarding residual gastric contents is not typically recommended for routine feeding and can lead to improper assessment.
