A congenital condition that includes mental retardation, short disproportional body size, and a thick tongue and neck is caused by __________.

  • A. insulin deficiency
  • B. deficiency of thymosin
  • C. deficiency of thyroxin
  • D. excess of synthetic growth hormone
Correct Answer: C

Rationale: Step 1: The congenital condition described points towards a disorder affecting growth and development.
Step 2: The symptoms of mental retardation, short body size, and thick neck suggest hypothyroidism.
Step 3: Thyroxin is a hormone produced by the thyroid gland that regulates metabolism and growth.
Step 4: A deficiency of thyroxin in congenital hypothyroidism leads to the described symptoms.
Step 5: Therefore, the correct answer is C: deficiency of thyroxin.

Summary:
A: Insulin deficiency does not match the symptoms described.
B: Thymosin deficiency is not related to growth and mental retardation.
D: Excess of synthetic growth hormone would not cause mental retardation and thick neck.

Identify the hormone that stimulates uterine contraction and the release of milk during nursing.

  • A. ADH.
  • B. glucagon
  • C. oxytocin
  • D. prolactin
Correct Answer: C

Rationale: Rationale:
1. Oxytocin is the hormone responsible for stimulating uterine contractions during labor and delivery.
2. Oxytocin also triggers the release of milk during nursing by causing contraction of the cells around the milk-filled alveoli.
3. ADH (A) regulates water balance, glucagon (B) regulates blood sugar levels, and prolactin (D) stimulates milk production but not milk release.
Summary: Oxytocin is the correct answer because it specifically stimulates uterine contractions and milk release during nursing, while the other choices are not directly related to these functions.

Which of the following is the most common adverse reaction during initial therapy with a thyroid replacement?

  • A. Allergy
  • B. Signs of hyperthyroidism
  • C. Weight loss
  • D. Bones become demineralized
Correct Answer: B

Rationale: Signs of hyperthyroidism are a common adverse reaction during initial therapy with thyroid replacement due to the body adjusting to the increased thyroid hormone levels.

Mrs. Jones, a 46-year-old diabetic, is 5'2\ and weighs 200 lb. Which area of health-care teaching should assume greatest priority for this patient?"

  • A. Exercise
  • B. Foot care

Most endocrine organs are prodded into action by other hormones; this type of stimulus is called:

  • A. hormonal stimulus
  • B. humoral stimulus
  • C. neural stimulus
  • D. receptor-mediated stimulus
Correct Answer: A

Rationale: The correct answer is A: hormonal stimulus. Endocrine organs are typically activated by other hormones circulating in the bloodstream, triggering a chain reaction of hormonal responses. This is known as hormonal stimulus. Other choices are incorrect because humoral stimulus refers to changes in blood levels of ions or nutrients, neural stimulus involves nerve impulses, and receptor-mediated stimulus is not a recognized term in endocrine physiology.

In addition to promoting the transport of glucose from the blood into the cell, what does insulin do?

  • A. Enhances the breakdown of adipose tissue for energy
  • B. Stimulates hepatic glycogenolysis and gluconeogenesis
  • C. Prevents the transport of triglycerides into adipose tissue
  • D. Accelerates the transport of amino acids into cells and their synthesis into protein
Correct Answer: D

Rationale: Insulin promotes the transport of glucose into cells and also enhances the transport of amino acids into cells, aiding protein synthesis.
