guide. Features highly detailed clinical rationales for every answer across essential primary care
systems, including cardiology, pediatrics, pharmacology, and ethics. Perfectly formatted for rapid
review to help FNP and AGPCNP students master high-yield topics, analyze diagnostic rationale,

1. Which of the following is a classic clinical finding in an infant with hypertrophic pyloric
stenosis?
A) Sausage-shaped mass in the right flank
B) Olive-shaped mass in the epigastrium
C) Currant-jelly stools
D) Generalized abdominal distension
B) Olive-shaped mass in the epigastrium
Hypertrophic pyloric stenosis classically presents in infants aged 3 to 6 weeks with
projectile, non-bilious vomiting after feeding. On physical examination, a small, hard,
olive-shaped mass can often be palpated in the right upper quadrant or epigastrium.
A sausage-shaped mass and currant-jelly stools are characteristic findings
associated with intussusception, not pyloric stenosis.
2. Which anti-hypertensive medication class is considered first-line for a diabetic patient
due to its renal-protective properties?
A) Calcium channel blockers
B) Beta-blockers
C) ACE inhibitors
D) Thiazide diuretics
C) ACE inhibitors
Angiotensin-converting enzyme (ACE) inhibitors, or angiotensin receptor blockers
(ARBs), are preferred first-line agents for patients with hypertension and concurrent
diabetes mellitus or chronic kidney disease. These medications dilate the efferent
arteriole in the kidneys, decreasing intraglomerular pressure and slowing the
progression of diabetic nephropathy.
3. A 65-year-old male presents with an acute onset of severe, tearing chest pain that
radiates to his back. What is the most likely diagnosis?
A) Acute myocardial infarction
B) Aortic dissection
, C) Acute pericarditis
D) Pulmonary embolism
B) Aortic dissection
An acute aortic dissection classically presents as a sudden, catastrophic onset of
"tearing" or "ripping" chest pain that radiates through to the back (interscapular
region). A key physical exam finding can also include blood pressure differentials
between the right and left arms. While acute myocardial infarction causes severe
chest pain, it is typically described as pressure or crushing rather than tearing.
4. Which of the following values is indicative of a positive diagnosis for diabetes
mellitus based on a fasting plasma glucose (FPG) test?
A) \(\ge \) 100 mg/dL
B) \(\ge \) 110 mg/dL
C) \(\ge \) 126 mg/dL
D) \(\ge \) 200 mg/dL
C) \(\ge \) 126 mg/dL
According to standard clinical practice guidelines, a fasting plasma glucose level of
126 mg/dL or higher on two separate occasions confirms a diagnosis of diabetes
mellitus. A level between 100 mg/dL and 125 mg/dL indicates prediabetes, while a
random plasma glucose level of 200 mg/dL or higher accompanied by symptoms
also meets diagnostic criteria.
5. What is the primary diagnostic imaging study used to confirm a suspected deep vein
thrombosis (DVT)?
A) Magnetic resonance imaging (MRI)
B) Venous duplex ultrasonography
C) Computed tomography (CT) venography
D) Contrast venography
B) Venous duplex ultrasonography
Venous duplex ultrasonography is the non-invasive diagnostic test of choice for
confirming a suspected deep vein thrombosis. It combines B-mode imaging with
Doppler flow evaluation to identify non-compressible veins or absent blood flow.
Contrast venography is the historical gold standard but is rarely used due to its
invasive nature.
,6. A patient presenting with a silver-scaly rash on their extensor surfaces (elbows and
knees) is most likely suffering from which dermatological condition?
A) Atopic dermatitis
B) Psoriasis vulgaris
C) Seborrheic dermatitis
D) Pityriasis rosea
B) Psoriasis vulgaris
Psoriasis vulgaris is a chronic autoimmune skin disease characterized by well-
demarcated, erythematous plaques covered with silvery scales. These plaques are
classically found on extensor surfaces such as the elbows, knees, and scalp. Atopic
dermatitis typically affects flexor surfaces and presents as pruritic, dry, eczematous
lesions.
7. Which cranial nerve is primarily affected in a patient diagnosed with Bell's palsy?
A) Cranial Nerve V (Trigeminal)
B) Cranial Nerve VII (Facial)
C) Cranial Nerve VIII (Vestibulocochlear)
D) Cranial Nerve X (Vagus)
B) Cranial Nerve VII (Facial)
Bell's palsy is an acute, unilateral peripheral facial nerve palsy caused by
inflammation or viral reactivation affecting Cranial Nerve VII (the facial nerve). This
leads to weakness or paralysis of the muscles of facial expression on the affected
side, including an inability to close the eye or wrinkle the forehead. Cranial Nerve V
controls facial sensation and mastication.
8. Which murmurs is characterized as a harsh, crescendo-decrescendo systolic
murmur that radiates to the carotids?
A) Mitral regurgitation
B) Aortic stenosis
C) Mitral stenosis
D) Aortic regurgitation
B) Aortic stenosis
Aortic stenosis presents as a harsh, crescendo-decrescendo systolic ejection
murmur heard best at the right upper sternal border, which classically radiates
upward into the carotid arteries. Mitral regurgitation is a holosystolic murmur heard
best at the apex radiating to the axilla, while aortic and mitral stenosis are diastolic
murmurs.
, 9. What is the first-line pharmacologic treatment for a patient diagnosed with mild-to-
moderate Alzheimer's disease?
A) Memantine
B) Donepezil
C) Haloperidol
D) Selegiline
B) Donepezil
Cholinesterase inhibitors like donepezil, rivastigmine, and galantamine are the
established first-line treatments to manage cognitive symptoms in mild-to-moderate
Alzheimer's disease. They work by increasing acetylcholine levels in the synaptic
cleft. Memantine is an NMDA receptor antagonist typically added or used during
moderate-to-severe stages.
10. Which laboratory marker is the most sensitive and specific for diagnosing an acute
myocardial infarction?
A) Creatine kinase-MB (CK-MB)
B) Myoglobin
C) Cardiac troponin I (cTnI)
D) Lactate dehydrogenase (LDH)
C) Cardiac troponin I (cTnI)
Cardiac troponins (I and T) are highly sensitive and specific biomarkers for
myocardial necrosis. They begin to rise within 3 to 4 hours following acute
myocardial injury and remain elevated for up to 10 to 14 days. CK-MB was
previously used but is less specific than troponin because it can also be released
from damaged skeletal muscle.
11. A 28-year-old female presents with a low-grade fever, a macular rash that started on
her face and spread to her trunk, and prominent postauricular and suboccipital
lymphadenopathy. Which condition should be suspected?
A) Rubeola (Measles)
B) Rubella (German Measles)
C) Varicella
D) Scarlet fever
B) Rubella (German Measles)
Rubella characteristically presents with a mild maculopapular rash that starts on the
face and spreads cephalocaudally, accompanied by prominent postauricular,
suboccipital, and posterior cervical lymphadenopathy. Rubeola (measles) presents
much more severely with high fevers, a cough, coryza, conjunctivitis, and Koplik
spots.
