A nurse is caring for an adolescent who has an allergy to penicillin. Which of the following prescriptions should the nurse clarify with the provider?

As individuals age, there is a natural decline in kidney function. This can result in a reduced ability to filter and excrete medications and their metabolites from the body. The decreased kidney function can lead to a longer half-life of medications, increased drug accumulation, and an increased risk of adverse drug reactions. It is important for the nurse to adjust medication dosages and frequencies based on the individual's renal function to prevent drug toxicity.

Increased liver function: Aging is associated with a gradual decline in liver function. While there may be some individual variations, in general, liver function decreases rather than increases with age. However, changes in liver function can affect the metabolism and elimination of medications. Some medications may require dosage adjustments based on liver function, but it is not a common physiological change in older adults.

Increased metabolism: Aging is generally associated with a decrease in metabolism rather than an increase. The metabolic rate tends to slow down with age, which can affect the pharmacokinetics of medications. Slower metabolism can result in medications taking longer to be metabolized and cleared from the body, potentially leading to prolonged drug effects.

Delegating tasks involves assigning appropriate responsibilities to assistive personnel based on their level of training, competency, and scope of practice. Performing indwelling urinary catheter care is a task that can be safely delegated to an AP who has received proper training and demonstrated competency in this skill. The nurse should ensure that the AP is familiar with the facility's policies and procedures regarding catheter care and can perform the task safely and effectively.

Demonstrating how to use an incentive spirometer requires specialized knowledge and the ability to provide clear instructions. It is typically within the scope of practice of licensed healthcare professionals, such as nurses or respiratory therapists, who have the necessary expertise to properly educate and guide patients in using an incentive spirometer. This task should not be delegated to an AP.

Measuring and assessing the depth of a pressure injury requires clinical judgment and accurate evaluation, which falls within the scope of practice of a licensed nurse. It involves understanding wound assessment, proper technique for measuring depth, and interpreting the findings. This task should be performed by the nurse rather than an AP.

Changing the appliance on a new colostomy involves skills such as assessing the stoma, selecting the appropriate appliance, and ensuring proper application. This task requires specialized knowledge and training in stoma care, and it should be performed by a licensed nurse who has the expertise in managing ostomies. It should not be delegated to an AP.
