MN 551 EXAMINATION TEST 2025/2026 QUESTIONS WITH
ANSWERS RATED A+
✔✔Following a long history of fatigue, weakness, and poor appetite, a 39-year-old male
has been diagnosed with hypopituitarism. Which of the following clinical findings would
most likely cause his care team to suspect that the man has an additional endocrine
disorder from a different source?
Question options:
The man displays the signs and symptoms of hypothyroidism.
The patient is 5 feet 2 inches tall and was consistently short for his age as a child.
The man has a chronic platelet deficiency and is occasionally anemic.
The man has a low sperm count and has been unable to have children. - ✔✔The man
has a chronic platelet deficiency and is occasionally anemic.
✔✔A 51-year-old woman has been experiencing signs and symptoms of
perimenopause and has sought help from her nurse practitioner. Doctors have
confirmed a deficiency in estrogen levels as a contributing factor. Which of the following
phenomena could potentially underlie the woman's health problem?
Question options:
A lack of prohormone precursors needed for estrogen synthesis and release
Insufficient estrogen production within the smooth endoplasmic reticulum of the relevant
cells
Inadequate synthesis in the rough endoplasmic reticulum of her ovarian cells
Sufficient synthesis of estrogen but inadequate vesicle-mediated release -
✔✔Insufficient estrogen production within the smooth endoplasmic reticulum of the
relevant cells
✔✔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. - ✔✔Up-
regulation has increased the sensitivity of the body to particular hormone levels.
✔✔A 30-year-old woman has sought care because of her recurrent photophobia,
tearing, and eye irritation. During assessment, her care provider asks about any history
of cold sores or genital herpes. What is the rationale for the care provider's line of
questioning?
Question options:
A history of HSV with eye irritation is suggestive of glaucoma.
Chronic viral infection of the eyes can result in HSV autoinoculation of the mouth and
labia.
HSV infection of the cornea is a common cause of corneal ulceration and blindness.
Herpes simplex virus (HSV) conjunctivitis indicates a need for antiviral rather than
antibacterial treatment. - ✔✔HSV infection of the cornea is a common cause of corneal
ulceration and blindness.
✔✔As part of the diagnostic workup for a patient's long-standing vertigo, a clinician
wants to gauge the patient's eye movements. Which of the following tests is the clinician
most likely to utilize?
Question options:
Caloric stimulation
Electronystagmography (ENG)
Rotational tests
Romberg test - ✔✔Electronystagmography (ENG)
✔✔A 21-year-old female is suspected of having inadequate function of her
hypothalamic-pituitary-thyroid system. Her care provider is planning to inject thyrotropin-
releasing hormone (TRH) and then measure her levels of TSH. Which of the following
diagnostic tests is being performed?
Question options:
Metabolite excretion test
Stimulation test
Radioimmunoassay (RIA) test
