Question

A young teen male has been in the <5% percentile on the growth chart for over 2 years due to abnormally decreased height. Which medication does the nurse expect the healthcare provider to consider to best treat deficiency in growth hormone?

Answers

  1. Levothyroxine
    • Rationale:

      This answer is not correct because levothyroxine is not prescribed to treat deficiency of growth hormone reflected by a consistent abnormal growth rate. Human growth hormone is responsible for the lengthening of bones often seen during puberty. Somatotropin is a synthetic growth hormone that can be administered to help growth abnormalities in young people.

  2. Somatotropin
    • Rationale:

      This answer is correct because somatotropin is a synthetic growth hormone. Generally, this is released from the anterior pituitary gland and stimulates growth of body tissues, including bone. Human growth hormone is responsible for the lengthening of bones often seen during puberty. If growth abnormalities are seen and reflected on growth charts consistently, somatotropin may be prescribed to promote bone growth.

  3. Cortisol
    • Rationale:

      This answer is not correct because cortisol is a steroid produced by the adrenal glands that is instrumental in regulating glucose, lipid, and protein metabolism. It also suppresses the immune system and helps maintain a normal blood pressure. Cortisol does not promote growth of bones. Human growth hormone is responsible for the lengthening of bones often seen during puberty.

  4. Gonadotropin
    • Rationale:

      This answer is not correct because gonadotropin hormones are follicle stimulating hormones (FSH) and luteinizing hormones (LH) which stimulate the testes or ovaries of a client to increase sex hormones and production of either sperm or ova. Although testosterone does promote muscle and bone growth, it is not the treatment for growth hormone deficiency. Somatotropin is a synthetic growth hormone. Generally, this is released from the anterior pituitary gland and stimulates growth of body tissues, including bone.

Overview

Somatotropin is a growth hormone and will most likely be considered to treat this teen male’s decreased height concerns.

Explanation

Learning Outcomes

Somatotropin is a synthetic growth hormone. Generally, this is released from the anterior pituitary gland and stimulates growth of body tissues, including bone. Human growth hormone is responsible for the lengthening of bones often seen during puberty. If growth abnormalities are seen and reflected on growth charts consistently, somatotropin may be prescribed to promote bone growth. Somatotropin is given by intramuscular injection in the evening, when the natural secretion of human growth hormone occurs. The client should be monitored carefully during the treatment and growth charted to reflect effectiveness.

Test Taking Tip

Watch the word, “best” to make sure you choose the best answer. Although testosterone does promote muscle and bone growth, it is not the treatment for growth hormone deficiency. Somatotropin is a synthetic growth hormone and is the best answer.
