A school nurse is assessing an adolescent who reports feeling shaky and is having difficulty speaking and concentrating on the questions the nurse is asking. The nurse checks the adolescent's blood glucose level and identifies a value of 55 mg/dL. Which of the following findings should the nurse expect?

A. Replacement therapy may require daily subcutaneous injections.

Explanation: Growth hormone deficiency (hypopituitarism) often requires treatment with growth hormone therapy. One common method of administering growth hormone is through daily subcutaneous injections. Subcutaneous injections involve injecting the medication under the skin into the fatty tissue. This is a routine part of growth hormone therapy, and nursing considerations would include educating the child and their family about proper injection techniques, site rotation, and adherence to the treatment schedule.

Explanation for the other choices:

B. Lifelong replacement therapy will be required:

This statement is generally true. Growth hormone deficiency often requires long-term treatment, which may extend throughout childhood and adolescence. However, in some cases, the need for growth hormone therapy might change based on the individual's response to treatment and growth patterns.

C. Treatment is most successful if started during adolescence:

The optimal timing for starting growth hormone therapy can vary depending on the specific circumstances and the underlying cause of growth hormone deficiency. While treatment during adolescence can be effective, growth hormone therapy can also be successful if started earlier in childhood or later in adolescence. The key is identifying and treating the deficiency as soon as possible to promote healthy growth.

D. Treatment is considered successful if children attain full stature by adulthood:

While growth hormone therapy aims to support growth, achieving "full stature" might not always be possible. The goal of treatment is to help the child reach a more typical height based on their genetic potential and individual response to therapy. The success of treatment is determined by improvements in growth velocity and height, rather than necessarily achieving "full stature," which can vary greatly among individuals.

To calculate the mL of phenytoin oral solution needed for a 250 mg dose, we can use the following equation:

Dose (mg) = Volume (mL) × Concentration (mg/mL)

Given:

Dose = 250 mg

Concentration = 25 mg/5 mL

We need to find the volume (mL):

Volume (mL) = Dose (mg) / Concentration (mg/mL)

Volume (mL) = 250 mg / (25 mg/5 mL)

Volume (mL) = 250 mg / (5 mg/mL)

Volume (mL) = 50 mL

So, the nurse should administer 50 mL of phenytoin oral solution per dose.
