A young adult patient who is being seen in the clinic has excessive secretion
of the anterior pituitary hormones. Which laboratory test result would the
nurse expect?
a. Increased urinary cortisol
b. Decreased serum thyroxine
,2|Page
c. Elevated serum aldosterone
d. Low urinary catecholamines ......-ANSWER-ANS: A
Increased secretion of adrenocorticotropic hormone (ACTH) by the anterior
pituitary gland will lead to an increase in serum and urinary cortisol levels.
An increase, rather than a decrease, in thyroxine level would be expected
with increased secretion of thyroid-stimulating hormone (TSH) by the
anterior pituitary. The anterior pituitary does not control aldosterone and
catecholamine levels.
Which statement made by a 50-yr-old female patient indicates to the nurse
that further assessment of thyroid function may be needed?
a. "I am so thirsty that I drink all day long."
b. "I get up several times at night to urinate."
c. "I feel a lump in my throat when I swallow."
d. "I notice my breasts are always tender lately." ......-ANSWER-ANS: C
An enlarged thyroid gland can cause problems swallowing or a change in
neck size. Nocturia is associated with diseases such as diabetes, diabetes
insipidus, or chronic kidney disease. Breast tenderness would occur with
excessive gonadal hormone levels. Thirst is a sign of disease such as diabetes.

A patient seen in the emergency department for severe headache and acute
confusion has a serum sodium level of 118 mEq/L. The nurse would
anticipate the need for which diagnostic test?
a. Urinary 17-ketosteroids
b. Antidiuretic hormone level
c. Growth hormone stimulation test
d. Adrenocorticotropic hormone level ......-ANSWER-ANS: B
Elevated levels of antidiuretic hormone will cause water retention and
decrease serum sodium levels. The other tests would not be helpful in
determining the cause of the patient's hyponatremia.
Which question from the nurse during a patient interview would provide
focused information about a possible thyroid disorder?
a. "What methods do you use to help cope with stress?"
b. "Have you experienced any blurring or double vision?"
c. "Have you had a recent unplanned weight gain or loss?"
d. "Do you have to get up at night to empty your bladder?"
......-ANSWER-ANS: C
Because thyroid function affects metabolic rate, changes in weight may
indicate hyperfunction or hypofunction of the thyroid gland. Nocturia, visual

difficulty, and changes in stress level are associated with other endocrine
disorders.
A patient is scheduled in the outpatient clinic for blood cortisol testing.
Which instruction would the nurse provide?
a. "Avoid adding any salt to your foods for 24 hours before the test."
b. "You will need to lie down for 30 minutes before the blood is drawn."
c. "Come to the laboratory to have the blood drawn early in the morning."
d. "Do not have anything to eat or drink before the blood test is obtained."
......-ANSWER-ANS: C
Cortisol levels are usually drawn in the morning, when levels are highest.
The other instructions would be given to patients who were having other
endocrine testing.
A patient admitted with pneumonia has a total serum calcium level of 13.3
mg/dL. Which serum level would the nurse anticipate will be tested next? a.
Calcitonin
b. Catecholamine
c. Thyroid hormone
d. Parathyroid hormone ......-ANSWER-ANS: D
