Emergency Nurse Practitioner Certification (ENP-BC) Practice Exam
,100 Questions with Answers and Rationales
1. A 55-year-old male presents with sudden onset, severe chest pain radiating to the back. Blood pressure is
190/110 mmHg in the right arm and 150/90 mmHg in the left arm. What is the priority diagnostic study?
A) 12-lead ECG
B) CT angiography of the chest
C) Transesophageal echocardiography
D) Troponin I level
Answer: B) CT angiography of the chest
Rationale: The presentation of tearing chest pain radiating to the back, pulse deficit, and blood pressure
differential between arms is classic for aortic dissection. CT angiography is the gold standard for rapid diagnosis
due to its speed and high sensitivity/specificity. ECG and troponin rule out MI but do not diagnose dissection.
TEE is sensitive but not the first-line test in the hemodynamically unstable or acutely symptomatic patient in the
ED.
,2. A patient with a history of atrial fibrillation on warfarin presents after a minor fall. CT head reveals an acute
subdural hematoma. What is the most critical reversal agent to administer?
A) Vitamin K and Fresh Frozen Plasma
B) Protamine sulfate
C) Four-factor Prothrombin Complex Concentrate (4F-PCC) and IV Vitamin K
D) Platelet transfusion
Answer: C) Four-factor Prothrombin Complex Concentrate (4F-PCC) and IV Vitamin K
Rationale: For life-threatening bleeding on warfarin, rapid reversal is paramount. 4F-PCC contains all vitamin K-
dependent factors and works immediately, whereas FFP takes time to type and infuse and is less effective for
INR reversal. IV Vitamin K is given to sustain the reversal as 4F-PCC's effect is temporary. Protamine is for
heparin reversal.
3. A 22-year-old female presents with right lower quadrant pain, fever, and nausea. Pelvic exam shows
mucopurulent cervical discharge and cervical motion tenderness. Urine pregnancy test is negative. What is the
most likely diagnosis?
A) Appendicitis
, B) Tubo-ovarian abscess
C) Pelvic Inflammatory Disease
D) Ectopic pregnancy
Answer: C) Pelvic Inflammatory Disease
Rationale: The triad of lower abdominal pain, cervical motion tenderness, and adnexal tenderness, along with
mucopurulent discharge and a negative pregnancy test, meets CDC clinical criteria for PID. While tubo-ovarian
abscess is a complication of PID, it's a more specific diagnosis often requiring imaging. Ectopic is ruled out by
the negative pregnancy test.
4. Which of the following is the most appropriate initial intervention for a patient presenting with symptomatic
bradycardia, a heart rate of 35 bpm, and hypotension?
A) Transcutaneous pacing
B) Atropine 0.5 mg IV
C) Dopamine infusion
D) Epinephrine infusion
