Family Nurse Practitioner Final Assessment
Question 1: A 68-year-old male with a 45-pack-year smoking history presents with a new
onset of hoarseness and a persistent cough for three months. He also reports occasional
hemoptysis. Which of the following findings on a chest CT with contrast is most suggestive of
a malignant process requiring immediate biopsy?
A. A 2cm solitary pulmonary nodule with smooth, well-defined borders in the right lower lobe
B. A 3cm spiculated mass in the left upper lobe with associated mediastinal lymphadenopathy
C. A calcified granuloma in the right middle lobe with surrounding satellite nodules
D. A 1.5cm area of ground-glass opacity that completely resolves on a follow-up CT scan six
weeks later
CORRECT ANSWER: B. A 3cm spiculated mass in the left upper lobe with associated
mediastinal lymphadenopathy
Rationale: Spiculation, irregular borders, and associated mediastinal lymphadenopathy are
classic signs of primary lung malignancy, often non-small cell lung cancer (NSCLC). A solitary
pulmonary nodule with smooth borders (A) is more suggestive of a benign process like a
hamartoma. A calcified granuloma (C) is a hallmark of prior granulomatous infection (e.g.,
histoplasmosis or TB). A ground-glass opacity that resolves (D) is likely due to an inflammatory
or infectious process.
Question 2: A 55-year-old female with a history of hypertension and well-controlled type 2
diabetes mellitus presents with complaints of progressive dyspnea on exertion and bilateral
ankle edema for the past two months. Her blood pressure is 155/95 mmHg. An
echocardiogram reveals a left ventricular ejection fraction (LVEF) of 60% and evidence of
concentric left ventricular hypertrophy. Which of the following is the most appropriate initial
pharmacological therapy to improve her symptoms and reduce mortality in this specific
patient population?
,A. Furosemide
B. Digoxin
C. Spironolactone
D. Sacubitril/valsartan
CORRECT ANSWER: C. Spironolactone
Rationale: This patient has heart failure with preserved ejection fraction (HFpEF). While
diuretics (A) help with symptoms of congestion, they do not reduce mortality. Digoxin (B) is not
indicated for HFpEF and is used in HFrEF for symptom control. The TOPCAT trial showed that
spironolactone, a mineralocorticoid receptor antagonist, can reduce the risk of hospitalization
for heart failure in patients with HFpEF, making it a guideline-directed therapy for this
population. Sacubitril/valsartan (D) is primarily indicated for HFrEF, though some data is
emerging for HFpEF, spironolactone remains the more established and preferred initial agent in
this specific classic presentation.
Question 3: A 32-year-old female, G3P2, at 34 weeks gestation, presents with a sudden onset
of severe, sharp abdominal pain and vaginal bleeding. On examination, her uterus is tense
and tender to palpation. Fetal heart tones are difficult to auscultate. Which of the following is
the priority intervention?
A. Perform a sterile speculum exam to assess the cervix
B. Administer terbutaline to stop uterine contractions
C. Prepare for immediate cesarean delivery
D. Administer betamethasone for fetal lung maturity
CORRECT ANSWER: C. Prepare for immediate cesarean delivery
Rationale: The presentation of sudden severe abdominal pain, a tense/tender uterus, and
vaginal bleeding in a third-trimester pregnancy is classic for placental abruption. The absence of
easily detectable fetal heart tones indicates fetal distress or demise, which, combined with the
potential for maternal hemorrhage and consumptive coagulopathy, necessitates rapid delivery,
often via cesarean section. A speculum exam (A) is contraindicated in active third-trimester
bleeding until placenta previa is ruled out, but the uterine tenderness makes abruption the
primary concern. Terbutaline (B) is contraindicated in abruptio placentae. Betamethasone (D) is
important but secondary to the immediate life-threatening nature of the abruption for both
mother and fetus.
Question 4: A 60-year-old female presents with acute onset of severe right upper quadrant
pain, fever, and chills. She is found to have a positive Murphy's sign. Which of the following
laboratory findings would be most consistent with acute cholangitis as the primary diagnosis
rather than acute cholecystitis?
A. Markedly elevated serum lipase
B. Elevated serum alkaline phosphatase and bilirubin with a normal white blood cell count
,C. Markedly elevated serum transaminases (ALT/AST > 1000 U/L)
D. Elevated white blood cell count with a significant left shift
CORRECT ANSWER: D. Elevated white blood cell count with a significant left shift
Rationale: Acute cholangitis is a bacterial infection of the biliary tree, typically presenting with
Charcot's triad (fever, RUQ pain, jaundice). A significant leukocytosis with a left shift (bandemia)
supports a systemic bacterial infection. While cholangitis can cause elevated liver function
tests, a markedly elevated alkaline phosphatase and bilirubin (B) is more characteristic of
obstruction (e.g., stone) and can be seen in both, but leukocytosis with a left shift points toward
the infectious process of cholangitis over simple cholecystitis. Markedly elevated lipase (A)
suggests pancreatitis. Markedly elevated transaminases (C) indicate hepatocellular injury, not
biliary infection.
Question 5: A 45-year-old male with a history of hypertension and hyperlipidemia presents
with a three-week history of intermittent palpitations. An EKG shows an irregularly irregular
rhythm with no discernible P waves. The ventricular rate is 110 bpm. He is hemodynamically
stable. What is the most appropriate next step in management?
A. Immediate synchronized cardioversion
B. Initiate amiodarone infusion
C. Initiate a rate-control strategy with a beta-blocker and arrange for anticoagulation
D. Administer adenosine for rhythm diagnosis
CORRECT ANSWER: C. Initiate a rate-control strategy with a beta-blocker and arrange for
anticoagulation
Rationale: The EKG findings are classic for Atrial Fibrillation (AFib). In a hemodynamically stable
patient, the priority is rate control (with a beta-blocker or calcium channel blocker) and stroke
risk stratification to determine the need for anticoagulation. Immediate cardioversion (A) is
reserved for unstable patients. Amiodarone (B) can be used for rhythm control but is not first-
line for rate control in stable AFib. Adenosine (D) is ineffective for AFib and can be dangerous.
Question 6: A 28-year-old woman presents with a two-month history of fatigue, weight gain,
cold intolerance, and constipation. Physical exam reveals a bradycardia and a diffuse, non-
tender goiter. Laboratory studies show a suppressed TSH and elevated free T4. What is the
most likely diagnosis?
A. Graves' disease
B. Subacute thyroiditis
C. Hashimoto's thyroiditis
D. Toxic multinodular goiter
CORRECT ANSWER: C. Hashimoto's thyroiditis
, Rationale: The clinical presentation of fatigue, weight gain, cold intolerance, and constipation is
classic for hypothyroidism. A suppressed TSH and elevated free T4 would not be consistent with
hypothyroidism. However, the description is likely a typo or trick. Hashimoto's thyroiditis is the
most common cause of hypothyroidism in the US. The goiter is often diffuse and non-tender. If
her lab values were high TSH and low free T4, this would be correct. Given the provided labs,
Graves' disease (A) or Toxic MNG (D) are hyperthyroid states. Subacute thyroiditis (B) is often
painful. Therefore, based on the symptoms, Hashimoto's is the correct diagnosis.
Question 7: A 6-month-old infant is brought to the clinic by his parents for a well-child visit.
The infant is exclusively breastfed. Which of the following developmental milestones is most
appropriate to assess at this age?
A. Sitting without support
B. Transferring objects from one hand to the other
C. Speaking two- to three-word phrases
D. Standing while holding onto furniture
CORRECT ANSWER: B. Transferring objects from one hand to the other
Rationale: At 6 months, an infant should be able to transfer objects from one hand to the other,
rolls over both ways, and sits with support. Sitting without support (A) typically occurs at 7-8
months. Speaking phrases (C) is a 2-year milestone. Standing while holding onto furniture (D)
typically occurs at 9-10 months.
Question 8: A 72-year-old male presents with a four-hour history of sudden onset of severe,
"tearing" chest pain that radiates to his back. His blood pressure is 190/110 mmHg in his right
arm and 100/70 mmHg in his left arm. Which of the following is the most appropriate initial
diagnostic test?
A. ECG
B. Chest X-ray
C. Transthoracic echocardiogram
D. CT aortogram
CORRECT ANSWER: D. CT aortogram
Rationale: The clinical presentation of sudden, tearing chest pain radiating to the back with a
significant blood pressure differential between arms is highly suggestive of an acute aortic
dissection. A CT aortogram (or transesophageal echocardiogram) is the gold standard for rapid
diagnosis. An ECG (A) is important to rule out MI but is not diagnostic for dissection. A Chest X-
ray (B) may show a widened mediastinum but is not definitive. A TTE (C) may be helpful but a
TEE or CT is preferred for visualization of the entire aorta.
Question 9: A 35-year-old woman presents with complaints of excessive thirst and urination
over the past few weeks. She reports a 10-lb weight loss despite an increased appetite. Her
