A nurse is reinforcing teaching with the parent of a newborn about security procedures. Which of the following instructions should the nurse include?

b. Platelet count 90,000/mm3.

Explanation:

During pregnancy, it is important to monitor the client's platelet count because a low platelet count can indicate a condition called gestational thrombocytopenia or other potential complications such as preeclampsia or HELLP syndrome. A platelet count of 90,000/mm3 is lower than the normal range and should be reported to the provider for further evaluation and management.

Option a, Hgb 12 g/dL, falls within the normal range for hemoglobin during pregnancy, which is typically between 11-13.5 g/dL. Therefore, it does not require immediate notification to the provider.

Option c, Hematocrit 37%, also falls within the normal range for hematocrit during pregnancy, which is typically between 33-42%. Therefore, it does not require immediate notification to the provider.

Option d, Creatinine 0.7 mg/dL, is within the normal range for creatinine levels and does not indicate any immediate concerns or need for notification to the provider.

It is important to remember that the interpretation of laboratory results should be done in the context of the client's individual clinical presentation and the healthcare provider's assessment. Any concerns or abnormal findings should be communicated to the provider for further evaluation and appropriate management.

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.
