A nurse is reinforcing teaching with the parents of a toddler who has a new diagnosis of asthma and a prescription for montelukast. Which of the following instructions should the nurse include in the teaching?

The first action the nurse should plan to perform is to check the client's ability to use the call light. This is essential to ensure that the client can easily communicate with the healthcare team if they need assistance or experience a fall risk situation. By confirming the client's ability to use the call light, the nurse can address any potential communication barriers and ensure that the client has a means to request help promptly.

Explanation for the other options:

b) Document the client's risk in the medical record: While documenting the client's risk in the medical record is important, it is not the first action to be taken. Ensuring the client's immediate safety and ability to request assistance is the priority.

c) Request a referral for physical therapy: Referring the client for physical therapy may be a necessary step to address their impaired mobility and reduce fall risk, but it is not the first action to be performed. Assessing their ability to use the call light takes precedence in order to address immediate safety concerns.

d) Place a gait belt in the client's room: Providing a gait belt is a measure to assist with mobility and falls prevention. However, it should not be the first action. Checking the client's ability to use the call light is more critical to ensure their immediate safety and ability to request help.

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.
