The charge nurse should explain to the assistive personnel (AP) that one of the responsibilities of a licensed practical nurse (LPN) is providing direct client care. LPNs work under the supervision of registered nurses (RNs) and are trained to deliver basic nursing care to clients. This includes tasks such as administering medications, monitoring vital signs, dressing wounds, assisting with activities of daily living (ADLs), and reporting any changes in the client's condition to the RN.

The other options are not typically within the scope of practice for an LPN:

a. Coordinating client care: The coordination of client care is primarily the responsibility of the RN. While LPNs may contribute to the coordination of care by providing input and collaborating with the healthcare team, the overall coordination is usually managed by the RN.

c. Assessing a client's health status: Assessing a client's health status is a role primarily performed by RNs. LPNs may gather data and contribute to the assessment process, but the comprehensive assessment and interpretation of data is typically the responsibility of the RN.

d. Identifying specific client health problems: Identifying specific client health problems and formulating nursing diagnoses is part of the RN's role. LPNs may assist in collecting data and providing input, but the identification and formulation of nursing diagnoses are within the scope of practice of the RN.

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.

Decreased pulmonary function: While it is true that lung function decreases with age, the impact on medication administration is not as significant compared to kidney function. Medications are usually administered through non-pulmonary routes (e.g., oral, intravenous, transdermal), and decreased pulmonary function primarily affects the absorption of inhaled medications. However, certain respiratory conditions or compromised lung function may influence medication choices or require adjusted dosing.
