Introduction
This comprehensive midterm examination is designed to rigorously assess the advanced knowledge and clinical
reasoning skills essential for success in NRNP 6552. The exam evaluates your understanding of core advanced
practice nursing concepts, including comprehensive health assessment, differential diagnosis, pharmacological
management, and the application of evidence-based guidelines. You will be presented with 100 multiple-choice
questions that integrate foundational theory with practical, real-world clinical scenarios. These questions are
crafted to challenge your critical thinking and decision-making abilities, emphasizing the safe, ethical, and
culturally competent care of patients across the lifespan. Successful completion of this exam demonstrates a
,readiness to apply complex clinical knowledge in diverse healthcare settings, ensuring the delivery of high-quality,
patient-centered care.
SECTION ONE: QUESTIONS 1-100
1. A 55-year-old male with a history of hypertension presents with a new onset of edema in his lower
extremities. His current medications include lisinopril and hydrochlorothiazide. Which of the following
pathophysiological mechanisms is most likely contributing to his edema?
A. Increased capillary hydrostatic pressure
B. Decreased capillary oncotic pressure
C. Increased capillary permeability
D. Lymphatic obstruction
🟢A
🔴 RATIONALE: Lisinopril, an ACE inhibitor, can lead to vasodilation and increased capillary hydrostatic
pressure, promoting fluid shift into the interstitial space and causing edema. While decreased oncotic pressure
(B) is associated with liver or kidney disease, and increased permeability (C) with inflammation, the most direct
mechanism related to this medication and presentation is increased hydrostatic pressure.
2. When assessing a patient's mental status, which of the following findings would be most indicative of
delirium rather than dementia?
A. Gradual onset of memory loss
B. Difficulty with complex problem-solving
C. Fluctuating level of consciousness
D. Aphasia and agnosia
,🟢C
🔴 RATIONALE: Delirium is characterized by an acute onset and a fluctuating course, including changes in level
of consciousness. Dementia (A, B, D) typically has a gradual onset with progressive cognitive decline without
significant fluctuations in consciousness, especially in the early stages.
3. A 68-year-old female with a history of osteoarthritis presents with a painful, swollen knee joint. The joint is
warm to the touch and erythematous. Aspiration of the joint reveals a white blood cell count of 45,000/mm³.
Which of the following is the most appropriate initial management?
A. Intra-articular corticosteroid injection
B. Oral nonsteroidal anti-inflammatory drugs (NSAIDs)
C. Empiric intravenous antibiotics
D. Joint aspiration and culture
🟢D
🔴 RATIONALE: The presentation of a hot, swollen, tender joint with a WBC count > 50,000/mm³ is highly
suggestive of a septic joint. The most appropriate initial management is to obtain a synovial fluid culture to
identify the causative organism and guide antibiotic therapy. Joint aspiration and culture (D) are essential for
diagnosis before initiating empiric antibiotics (C). NSAIDs (B) or steroids (A) would be inappropriate without
ruling out infection.
4. A patient is prescribed a new medication and develops a pruritic, maculopapular rash. Which of the
following types of adverse drug reactions is this most consistent with?
A. Type I hypersensitivity
B. Type II hypersensitivity
C. Type III hypersensitivity
D. Type IV hypersensitivity
, 🟢D
🔴 RATIONALE: A maculopapular rash is a classic example of a Type IV delayed-type hypersensitivity reaction,
which is T-cell mediated and typically occurs 48-72 hours after exposure to the drug. Type I (A) is an immediate
IgE-mediated reaction like anaphylaxis. Type II (B) is antibody-mediated cell destruction, and Type III (C) involves
immune complex deposition.
5. A 72-year-old male with a history of chronic obstructive pulmonary disease (COPD) presents with
worsening shortness of breath and increased sputum production. Which of the following findings on an
arterial blood gas (ABG) is most consistent with this acute exacerbation?
A. pH 7.38, PaCO2 48, HCO3 26
B. pH 7.46, PaCO2 30, HCO3 20
C. pH 7.32, PaCO2 55, HCO3 24
D. pH 7.40, PaCO2 40, HCO3 24
🟢C
🔴 RATIONALE: An acute exacerbation of COPD often results in respiratory acidosis due to hypoventilation and
CO2 retention. ABG results would show a low pH (<7.35) and elevated PaCO2 (>45). Option C (pH 7.32, PaCO2
55, HCO3 24) indicates acute respiratory acidosis without renal compensation yet.
6. According to the Health Belief Model, which of the following factors is most strongly associated with a
patient's likelihood to adhere to a new treatment regimen?
A. The patient's age and gender
B. The patient's perceived susceptibility to the illness
C. The patient's socioeconomic status
D. The patient's perceived barriers to treatment
