Question 1
Regular
The nurse is evaluating the laboratory results for a patient who has increased secretion of the anterior pituitary hormones. Which of the following findings should the nurse anticipate when reviewing the laboratory findings?
Correct!
Incorrect
The correct answer is: C
Rationale
C: An increase in urinary free cortisol. Elevated anterior pituitary hormones, particularly adrenocorticotropic hormone (ACTH), stimulate cortisol production in the adrenal glands, leading to increased levels of cortisol excreted in urine.
A: Decreased serum thyroxine levels. Anterior pituitary hormones generally enhance thyroid function, resulting in increased thyroxine production rather than a decrease in serum levels.
B: Elevated serum aldosterone levels. While ACTH may influence adrenal function, aldosterone secretion is primarily regulated by the renin-angiotensin system, not directly by anterior pituitary hormones.
D: Low urinary excretion of catecholamines. Anterior pituitary hormone excess typically does not correlate with decreased catecholamine levels, as catecholamines are mainly secreted by the adrenal medulla, independent of pituitary activity.
Correct Answer: C
Rationale: C: An increase in urinary free cortisol. Elevated anterior pituitary hormones, particularly adrenocorticotropic hormone (ACTH), stimulate cortisol production in the adrenal glands, leading to increased levels of cortisol excreted in urine.
A: Decreased serum thyroxine levels. Anterior pituitary hormones generally enhance thyroid function, resulting in increased thyroxine production rather than a decrease in serum levels.

Question 2
Regular
The nurse is obtaining the health history from a patient. Which of the following statements by the patient indicates further assessment of thyroid function may be necessary?
Correct!
Incorrect
The correct answer is: D
Rationale
I feel a lump in my throat when I swallow. This statement suggests a potential enlargement or abnormality in the thyroid gland, necessitating further assessment to evaluate thyroid function and possible underlying conditions affecting the patient’s health.
A: I notice my breasts are tender lately. Breast tenderness typically relates to hormonal changes or other non-thyroid related issues, not directly indicating a need for thyroid function evaluation.
B: I am so thirsty that I drink all day long. Excessive thirst can indicate other conditions, such as diabetes, which are unrelated to thyroid function, thus not warranting further thyroid assessment.
C: I get up several times at night to urinate. Nocturia may be tied to various factors like fluid intake or urinary tract issues, rather than suggesting any immediate thyroid dysfunction concerns.
