1. A 24-year-old female presents at 10 weeks gestation for her initial prenatal
visit. She has no significant past medical history. Which of the following
medications is considered safe for routine use during pregnancy?
A) Lisinopril
B) Warfarin
C) Isoretinoin
D) Acetaminophen
Answer: D) Acetaminophen
Rationale: Acetaminophen is generally recognized as safe for pain relief and fever
reduction during pregnancy when used at therapeutic doses. Lisinopril (an ACE
inhibitor) is highly teratogenic, especially in the second and third trimesters, causing
fetal renal failure and skull hypoplasia. Warfarin crosses the placenta and can cause
fetal warfarin syndrome and hemorrhage. Isotretinoin is a potent teratogenic retinoid
that causes severe central nervous system, facial, and cardiovascular defects.
Question 2
A 4-month-old infant is brought to the clinic for a well-child checkup. The nurse
practitioner assesses the infant's developmental milestones. Which of the following
tasks should a healthy 4-month-old infant be able to perform?
A) Sitting independently without support
B) Rolling from stomach to back
C) Exhibiting clear object permanence
D) Speaking two to three distinct words
Answer: B) Rolling from stomach to back
,Rationale: At 4 months of age, infants typically develop the gross motor skill to roll
from a prone position (stomach) to a supine position (back). Sitting independently
without support is a milestone achieved around 6 months. Object permanence
begins to develop later, around 4 to 7 months, but is not fully established until closer
to 8 to 12 months. Speaking distinct words occurs around 12 months.
Question 3
A 55-year-old male with a history of hypertension presents with severe, sudden-
onset retrosternal chest pain that radiates to his back between the scapulae. He
describes the pain as a "tearing" sensation. His blood pressure is 185/110 mmHg in
the right arm and 140/85 mmHg in the left arm. What is the most likely diagnosis?
A) Acute myocardial infarction
B) Acute aortic dissection
C) Pulmonary embolism
D) Acute pericarditis
Answer: B) Acute aortic dissection
Rationale: The classic presentation of an aortic dissection includes sudden, severe
chest pain described as "tearing" or "ripping" that radiates to the back. A key physical
exam finding is a significant discrepancy in blood pressure readings between the
upper extremities (greater than 20 mmHg). While acute myocardial infarction causes
severe chest pain, it does not typically produce a blood pressure differential between
arms or a tearing sensation radiating to the back.
Question 4
A nurse practitioner is reviewing lab results for a patient taking a thiazide diuretic for
hypertension. Which of the following electrolyte abnormalities is a known adverse
effect of this medication class?
A) Hyperkalemia
B) Hypokalemia
C) Hypouricemia
D) Hyponatremia
Answer: B) Hypokalemia
Rationale: Thiazide diuretics inhibit sodium and chloride reabsorption in the distal
convoluted tubule, increasing delivery of sodium and water to the collecting duct.
This accelerates potassium excretion, commonly leading to hypokalemia. Thiazides
also cause hyperuricemia (which can precipitate gout) and hyponatremia, rather than
hyperkalemia or hypouricemia.
,Question 5
A 19-year-old college student presents with a high fever, severe headache, and a
stiff neck. On physical examination, the nurse practitioner notes a positive Brudzinski
sign and a petechial rash on the lower extremities. What is the immediate priority
action?
A) Order a head CT scan and wait for the results
B) Administer a dose of oral acetaminophen and send the patient home
C) Arrange immediate transfer to the emergency department for a lumbar puncture
and IV antibiotics
D) Perform an in-office throat culture to rule out streptococcal pharyngitis
Answer: C) Arrange immediate transfer to the emergency department for a
lumbar puncture and IV antibiotics
Rationale: The clinical triad of fever, headache, and nuchal rigidity (stiff neck),
combined with a positive Brudzinski sign and a petechial rash, strongly indicates
acute bacterial meningitis (likely Neisseria meningitidis). This is a life-threatening
medical emergency requiring immediate hospitalization, diagnostic lumbar puncture,
and prompt initiation of intravenous antibiotics. Delaying care for outpatient imaging
or lab work can result in death or permanent neurological damage.
Question 6
A 32-year-old female presents to the clinic requesting a refill on her combined oral
contraceptive pills. She mentions that she forgot to take her pill yesterday but took
today's pill on schedule. What advice should the nurse practitioner provide?
A) Discontinue the pack entirely and wait for her next menstrual cycle to start a new
one
B) Take the missed pill immediately, continue taking the remaining pills as
scheduled, and use a backup contraceptive method for 7 days
C) Take the missed pill immediately and continue the pack as scheduled; no backup
contraceptive method is needed
D) Take two pills daily for the next three days to catch up
Answer: C) Take the missed pill immediately and continue the pack as
scheduled; no backup contraceptive method is needed
Rationale: According to standard family planning guidelines, if a woman misses
exactly one active combined oral contraceptive pill, she should take the missed pill
as soon as she remembers (even if it means taking two pills in one day). She should
then continue taking the rest of the pack at her regular time. No emergency
contraception or backup method is required if only one pill is missed, provided the
previous pills were taken consistently.
, Question 7
A 68-year-old female presents with complaints of worsening fatigue, cold intolerance,
and unexpected weight gain over the past three months. Lab evaluation reveals a
serum Thyroid-Stimulating Hormone (TSH) level of 14.2 mIU/L and a low free T4
level. Which medication should be initiated?
A) Methimazole
B) Levothyroxine
C) Propylthiouracil
D) Radioactive iodine
Answer: B) Levothyroxine
Rationale: The patient's symptoms (fatigue, cold intolerance, weight gain) combined
with an elevated TSH and low free T4 are diagnostic of primary hypothyroidism.
Levothyroxine (synthetic T4) is the drug of choice for thyroid hormone replacement.
Methimazole and propylthiouracil are antithyroid medications used to treat
hyperthyroidism. Radioactive iodine is used to ablate the thyroid gland in cases of
hyperthyroidism or thyroid cancer.
Question 8
An 8-year-old child presents with a sudden onset of tea-colored urine, periorbital
edema, and mild hypertension. The parents note the child recovered from a severe
sore throat about two weeks ago. What is the most likely diagnosis?
A) Acute pyelonephritis
B) Minimal change disease
C) Post-streptococcal glomerulonephritis
D) Nephrolithiasis
Answer: C) Post-streptococcal glomerulonephritis
Rationale: Post-streptococcal glomerulonephritis (PSGN) typically presents 1 to 3
weeks after a Group A beta-hemolytic streptococcal infection (pharyngitis or
impetigo). Classic features include hematuria (resulting in tea-colored or cola-colored
urine), oliguria, edema (often periorbital), and hypertension. Minimal change disease
causes severe proteinuria and generalized edema but typically lacks the gross
hematuria and specific post-infectious timeline.
Question 9
During a routine physical exam of a 72-year-old male, the nurse practitioner
auscultates a harsh, crescendo-decrescendo systolic murmur at the second right
