Introduction
The purpose of this midterm assessment is to evaluate the student’s mastery of advanced nursing practice
concepts.
This exam assesses critical clinical skills, pharmacological knowledge, and the ability to synthesize
complex physiological
data into actionable diagnostic plans. Through a combination of multiple-choice questions and
scenario-based
evaluations, the assessment mirrors real-world clinical decision-making. Emphasis is placed on the
application
of evidence-based practice, professional ethics, and regulatory compliance. Candidates must
demonstrate high-level
critical thinking and diagnostic accuracy to ensure patient safety and optimal outcomes.
SECTION ONE: QUESTIONS 1–100
1. A patient presents with acute shortness of breath and unilateral leg swelling. Which diagnostic tool is
the gold standard for confirming a suspected pulmonary embolism?
A. Chest X-ray
B. D-dimer assay
C. CT Angiography
D. Ventilation-Perfusion (V/Q) Scan
,🟢 Correct answer C
🔴 Explanation: CT Angiography is considered the gold standard for pulmonary embolism due to its high
sensitivity and ability to visualize the pulmonary vasculature directly.
2. Which of the following best describes the physiological mechanism of ACE inhibitors in managing
hypertension?
A. Blocking calcium channels in smooth muscle
B. Inhibiting the conversion of Angiotensin I to Angiotensin II
C. Directly relaxing peripheral arterioles
D. Stimulating beta-2 adrenergic receptors
🟢 Correct answer B
🔴 Explanation: ACE inhibitors lower blood pressure by preventing the formation of Angiotensin II, a potent
vasoconstrictor, which also reduces aldosterone secretion.
3. A 65-year-old male with a history of COPD presents with increased sputum production and fever.
Which organism is the most common cause of bacterial exacerbations in COPD?
A. Streptococcus pneumoniae
B. Mycoplasma pneumoniae
C. Haemophilus influenzae
D. Pseudomonas aeruginosa
🟢 Correct answer C
🔴 Explanation: While S. pneumoniae is common in community-acquired pneumonia, Haemophilus
influenzae is a leading cause of exacerbations in patients with chronic obstructive pulmonary disease.
4. Which ethical principle is primarily involved when a clinician provides a patient with all necessary
information to make an informed decision about a procedure?
,A. Beneficence
B. Non-maleficence
C. Justice
D. Autonomy
🟢 Correct answer D
🔴 Explanation: Autonomy refers to the patient's right to self-determination and making informed choices
about their own medical care.
5. A patient on long-term warfarin therapy presents with an INR of 7.5 and no active bleeding. What is the
most appropriate initial intervention?
A. Administering 10mg of Vitamin K intravenously
B. Holding the next few doses of warfarin and reassessing
C. Immediate transfusion of Fresh Frozen Plasma (FFP)
D. Administering oral Vitamin K (2.5mg to 5mg)
🟢 Correct answer D
🔴 Explanation: For an INR between 4.5 and 10 with no bleeding, the recommendation is to hold warfarin
and provide a small dose of oral Vitamin K to lower the INR safely.
6. In the context of evidence-based practice, which level of evidence is considered the highest?
A. Case-control studies
B. Randomized controlled trials (RCTs)
C. Systematic reviews of RCTs
D. Expert consensus opinions
🟢 Correct answer C
🔴 Explanation: Systematic reviews and meta-analyses of multiple randomized controlled trials represent
the highest tier of evidence because they synthesize data from multiple high-quality sources.
, 7. A patient with Type 2 Diabetes is started on Metformin. Which lab value must be monitored to prevent
the risk of lactic acidosis?
A. Serum Potassium
B. Glomerular Filtration Rate (GFR)
C. Alanine Aminotransferase (ALT)
D. Glycated Hemoglobin (A1C)
🟢 Correct answer B
🔴 Explanation: Metformin is renally excreted; a low GFR (typically <30 mL/min) significantly increases the
risk of metformin-associated lactic acidosis.
8. Which physical exam finding is most suggestive of a tension pneumothorax?
A. Dullness to percussion on the affected side
B. Tracheal deviation toward the affected side
C. Tracheal deviation away from the affected side
D. Increased breath sounds on the affected side
🟢 Correct answer C
🔴 Explanation: Tension pneumothorax involves a build-up of pressure that shifts the mediastinum and
trachea toward the contralateral (opposite) side.
9. A patient presents with sudden onset of "the worst headache of my life." What is the most likely
diagnosis?
A. Cluster headache
B. Migraine with aura
C. Subarachnoid hemorrhage
D. Temporal arteritis
🟢 Correct answer C
