A nurse is caring for a child who has terminal cancer.

Which of the following responses by the child's siblings should the nurse expect?

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.

Answer: (C) The client is not grimacing

Rationale:

A) The client's blood pressure has been reduced:

While morphine can lower blood pressure due to its vasodilatory effects, a reduction in blood pressure is not necessarily a primary indicator of a therapeutic response to pain relief. It is more important to assess pain relief directly through the client's subjective experience and behavior rather than focusing on vital signs alone.

B) The client exhibits diaphoresis:

Diaphoresis, or sweating, can occur as a side effect of morphine administration but does not indicate that the medication is effectively relieving pain. In fact, diaphoresis might signal an adverse reaction or discomfort rather than a therapeutic effect.

C) The client is not grimacing:

The absence of grimacing suggests that the client's pain has decreased, which is a direct indicator of a therapeutic response to morphine. Observing a reduction in pain-related behaviors, such as grimacing, is a key assessment for determining the effectiveness of pain management in postoperative clients.

D) The client has an elevated heart rate:

An elevated heart rate may be a sign of unresolved pain or a side effect of morphine but is not a clear indicator of pain relief. Effective pain management with morphine typically results in a decrease in sympathetic nervous system responses, such as a high heart rate, rather than an increase.
