MEDICAL SURGICAL NURSING ENDOCRINE SYSTEM
QUESTIONS WITH ACCURATE ANSWERS
1
Cortisol is a glucocorticoid that protects the body from stress; it is also called as
stress hormone. Cortisol helps to maintain vascular integrity and fluid volume;
cortisol levels are increased in patients with burns, infections, fevers, and acute
anxiety. The level of oxytocin, aldosterone, and antidiuretic hormone does not
increase in response to stress.
Text Reference - p. 1140 correct answer A patient is admitted to the hospital with
severe burns. Which hormone level does the nurse expect to be elevated in the
patient's laboratory reports?
1
Cortisol
2
Oxytocin
3
Aldosterone
4
Antidiuretic hormone

Cortisol level increases if a patient has fever, stress, burns, infection, acute
anxiety, or hypoglycemia. A body temperature of 104o F indicates that the patient
,has fever. The normal white blood cell count is 4500 to 10,000/microliter. A white
blood cell count of 14,000/microliter indicates that the patient may have an
infection. The normal fasting blood glucose levels of a patient are 70 to 100
mg/dL. Blood glucose levels of 65 mg/dL indicate that the patient has
hypoglycemia. Therefore, the nurse expects to find high levels of cortisol in the
patient. Fever, infection, and hypoglycemia may not enhance the secretion of
aldosterone. Androstenedione and dehydroepiandrosterone are adrenal
hormones. They are not elevated because of fever, infection, or hypoglycemia.
Text Reference - p. 1140 correct answer The nurse reviews a patient's medical
record and notes assessment findings. Which endocrine hormone level does the
nurse expect to be increased in the patient?
1
Cortisol
2
Aldosterone
3
Androstenedione
4
Dehydroepiandrosterone

Estrogen is secreted from the woman's ovaries and stimulates the development
of secondary sex characteristics. It prepares the uterus for fertilization and
stimulates bone growth. Decreased estrogen secretion increases the risk for
atherosclerosis and osteoporosis. Progesterone maintains the lining of the uterus
for successful pregnancy. Epinephrine and norepinephrine increase in response to
stress and enhance the effects of the sympathetic nervous system.
, Test-Taking Tip: You have at least a 25 percent chance of selecting the correct
response in multiple-choice items. If you are uncertain about a question,
eliminate the choices that you believe are wrong and then call on your
knowledge, skills, and abilities to choose from the remaining responses.
Text Reference - p. 1136 correct answer An adult patient is experiencing
menopause-related symptoms. Which hormone decline results in an increased
risk of atherosclerosis and osteoporosis?
1
Estrogen
2
Epinephrine
3
Progesterone
4
Norepinephrine

Hypothyroidism refers to a condition in which the patient will have low levels of
total thyroxine (T4) and free thyroxine (FT4) in blood. The normal levels of total
thyroxine (T4) and free thyroxine (FT4) are 59 to 142 nmol/L and 10 to 35 pmol/L
respectively. Therefore, T4 and FT4 levels of 50 nmol/L and 5 pmol/L indicate
hypothyroidism. T4 and FT4 levels of 60 nmol/L and 20 pmol/L are normal
findings. T4 and FT4 levels of 70 nmol/L and 30 pmol/L do not indicate
hypothyroidism, because these values fall within the range of normal levels. T4
and FT4 levels of 80 nmol/L and 35 pmol/L do not indicate hypothyroidism,
because these values are within the normal range.
