Which of the following statements best captures the role of the adrenal cortex in
maintaining homeostasis?
Question 1 options:
A. Normal sexual function is dependent on adequate adrenal cortical function.
B. Redundant, secondary production of adrenal cortical hormones can compensate
for the loss of the adrenal glands.
C. The adrenal cortical hormones are primarily steroids and sex hormones.
D. The adrenal cortex is responsible for the production of epinephrine and
norepinephrine, which are part of the sympathetic nervous system.

,A patient with a history of an endocrine disorder exhibits signs and symptoms of
hormone deficiency. Which of the following processes would the patient's care team
most likely rule out first as a contributing factor?
Question options:
Up-regulation has increased the sensitivity of the body to particular hormone levels.
The process of down-regulation has resulted in decreased hormone sensitivity.
Hormone production is sufficient, but affinity on the part of the target cells is lacking.
The patient's target cells lack sufficient receptors for the hormone in question.

A patient in the intensive care unit who has a brain tumor has experienced a sharp
decline. The care team suspects that water and protein have crossed the blood-brain
barrier and been transferred from the vascular space into the patient's interstitial
space. Which of the following diagnoses best captures this pathophysiology?

Vasogenic edema
Hydrocephalus
Cytotoxic edema

Hypothyroidism
A 60-year-old man has long managed his type 1 diabetes effectively with a
combination of vigilant blood sugar monitoring, subcutaneous insulin administration,
and conscientious eating habits. This morning, however, his wife has noted that he
appears pale and clammy and to be in a stupor, though he is responsive. She suspects
that he has made an error in his insulin administration and that he is experiencing a
hypoglycemic episode. Which of the following actions should be the wife's first
choice?
Careful monitoring for level of consciousness and resolution of hypoglycemia
IV infusion of 50% dextrose and water solution
Administration of subcutaneous glucagon
Administration of 15 to 20 g of glucose in a concentrated carbohydrate source

A patient with a new diagnosis of an endocrine disorder is unclear about how the
body can control the levels of different hormones over time. Which of the following
statements most accurately underlies the dominant regulation process of hormone
levels in the body?
Question 8 options:
The pituitary gland is genetically programmed to stimulate and inhibit hormone
production and/or release based on needs at different points in the life cycle.
The hypothalamus ensures that hormone levels correspond accurately to the diurnal
cycle.
With input from various sensors, hormone production and release are adjusted based
on existing hormone levels.
A positive feedback cycle ensures that stable levels of hormones exist in the body
over time.

(BMI) of 12.0 (normal is 18.5 to 24.9).
