A clinic nurse is performing teaching with the parent of a child with a growth hormone deficiency. Which of the following will the nurse include in patient education? Select all that apply.

Administration is parenteral—IM or subQ only. Subcutaneous administration is preferred because it is less painful than IM while being just as safe and effective. Subcutaneous administration can be done using either a traditional syringe and needle or a pre-filled injection device. To avoid local tissue atrophy, the injection site should be rotated. Height and weight must be monitored monthly. Continue therapy until a satisfactory adult height has been achieved, until epiphyseal closure occurs, or until a response can no longer be elicited (usually by age 20 to 24). Close follow-up is required to monitor epiphyseal closure, GH, thyroid function, and potential adverse effects. Monitor glucose levels closely in patients diagnosed with diabetes. GH can elevate plasma glucose levels in diabetics. Increase insulin dosage as needed.

Antidiuretic Hormone (Vasopressin)

Adverse effect of excessive water retention can cause water intoxication with early signs of drowsiness, listlessness, and headache; progressing to severe intoxication with convulsions and terminal coma powerful vasoconstrictor actions which can cause severe adverse cardiovascular effects; angina to MI patients should be instructed to reduce their accustomed intake of fluid

The clinical nursing instructor is preparing a lecture on drugs for adrenocortical insufficiency. Which of the following options will the instructor correctly include in the review? Select all that apply.

Hydrocortisone is a preferred drug for all forms of adrenocortical insufficiency. Hydrocortisone and other glucocorticoids are used to treat a broad spectrum of nonendocrine disorders, ranging from allergic reactions to inflammation to cancer. The doses required are considerably higher than those employed for replacement therapy. Fludrocortisone causes elevation of blood pressure due to mineralocorticoid actions. Hydrocortisone is a synthetic steroid with a structure identical to that of cortisol, the principal glucocorticoid produced by the adrenal cortex.

Negative feedback loop

Hypothalamic and anterior pituitary hormones release regulation

Glucocorticoids

Levothyroxine

Inform patients about symptoms of thyrotoxicosis (tachycardia, angina, tremor, nervousness, insomnia, hyperthermia, heat intolerance, sweating), and instruct them to notify the prescriber if these develop. Instruct the patient to take levothyroxine on an empty stomach in the morning, at least 30 to 60 minutes before breakfast. Provide education of treatment is designed to resolve signs and symptoms of hypothyroidism and restoration of normal laboratory values for serum TSH and free T4.

The nurse is preparing to administer the antidiuretic hormone vasopressin. Which of the following does the nurse know are correct regarding this drug? Select all that apply.

It is important to determine creatinine clearance and fluid and electrolyte status. Excessive retention of water can produce water intoxication—most often at the beginning of therapy. Instruct patients to decrease their accustomed fluid intake at the start of treatment. Inform patients about early signs of water intoxication Teach the patient to monitor and record daily intake and output of fluid. To promote adherence, make certain the patient understands that treatment is lifelong. The drug will not cure diabetes insipidus. Diabetes insipidus is the same as diabetes mellitus: Deficiency of ADH produces hypothalamic diabetes insipidus, a condition in which large volumes of dilute urine are produced. Diabetes mellitus is sustained hyperglycemia.
