ADVANCED NURSING STUDY GUIDE | 200 QUESTIONS WITH VERIFIED ANSWERS
& EXPERT RATIONALE
Q1. A 58-year-old male presents with crushing chest pain radiating to the left
arm, diaphoresis, and nausea. His ECG shows ST-segment elevation in leads II,
III, and aVF. Which coronary artery is most likely occluded?
A. Left anterior descending artery
B. Left circumflex artery
C. Right coronary artery
D. Left main coronary artery
E. Posterior descending artery
✓ Correct Answer: C. Right coronary artery
EXPERT RATIONALE: ST-elevation in leads II, III, and aVF indicates an inferior wall
STEMI. The right coronary artery (RCA) supplies the inferior wall of the left ventricle
in approximately 85% of individuals, making RCA occlusion the most common
cause of inferior STEMI.
,Q2. A patient with heart failure is started on lisinopril. Which mechanism best
explains the therapeutic benefit of this drug in heart failure?
A. Increases preload by promoting sodium retention
B. Blocks beta-adrenergic receptors reducing heart rate
C. Inhibits ACE, reducing angiotensin II and aldosterone levels
D. Directly dilates coronary arteries improving perfusion
E. Increases myocardial contractility via calcium channel activation
✓ Correct Answer: C. Inhibits ACE, reducing angiotensin II and aldosterone
levels
EXPERT RATIONALE: Lisinopril is an ACE inhibitor. By blocking the conversion of
angiotensin I to angiotensin II, it reduces vasoconstriction and aldosterone
secretion, thereby decreasing both preload and afterload — hallmarks of heart
failure management.
Q3. A graduate nurse practitioner is assessing a patient with suspected
cardiac tamponade. Which classic triad of findings should the NP anticipate?
A. Hypertension, bradycardia, and widened pulse pressure
B. Hypotension, muffled heart sounds, and jugular venous distension
C. Tachycardia, pulmonary edema, and S3 gallop
D. Pulsus alternans, friction rub, and ST elevation
E. Fever, pleuritic chest pain, and pericardial rub
✓ Correct Answer: B. Hypotension, muffled heart sounds, and jugular venous
distension
EXPERT RATIONALE: Beck's Triad — hypotension, muffled heart sounds, and
jugular venous distension (JVD) — is the classic clinical presentation of cardiac
,tamponade, resulting from fluid accumulation in the pericardial sac compressing
the heart.
Q4. Which of the following hemodynamic parameters is most directly
increased in hypovolemic shock?
A. Cardiac output
B. Central venous pressure
C. Systemic vascular resistance
D. Pulmonary artery wedge pressure
E. Mixed venous oxygen saturation
✓ Correct Answer: C. Systemic vascular resistance
EXPERT RATIONALE: In hypovolemic shock, reduced circulating volume leads to
decreased cardiac output. Compensatory sympathetic activation causes
vasoconstriction, increasing systemic vascular resistance (SVR) to maintain blood
pressure.
Q5. A 65-year-old woman presents with progressive dyspnea and bilateral
crackles on auscultation. BNP is 1,200 pg/mL. Which pathophysiological
mechanism best explains her pulmonary findings?
A. Increased pulmonary vascular resistance causing right heart strain
B. Elevated left ventricular end-diastolic pressure causing pulmonary venous
hypertension
C. Alveolar consolidation from bacterial pneumonia
D. Bronchospasm causing air trapping and hyperinflation
E. Pleural effusion compressing the lower lobes bilaterally
✓ Correct Answer: B. Elevated left ventricular end-diastolic pressure causing
pulmonary venous hypertension
, EXPERT RATIONALE: In left-sided heart failure, the LV fails to eject blood effectively,
causing elevated end-diastolic pressures. This backs up into the pulmonary veins,
causing pulmonary venous hypertension and transudation of fluid into the alveoli
— producing the bilateral crackles heard on auscultation.
Q6. A patient with Type 2 diabetes mellitus and CKD Stage 3 requires glycemic
control. Which agent is MOST appropriate?
A. Metformin 1000 mg twice daily
B. Empagliflozin 10 mg daily
C. Linagliptin 5 mg daily
D. Glipizide 10 mg daily
E. Sitagliptin 100 mg daily
✓ Correct Answer: C. Linagliptin 5 mg daily
EXPERT RATIONALE: Linagliptin is the only DPP-4 inhibitor that does not require
renal dose adjustment because it is eliminated hepatically (>90% excreted in
bile/feces). It is safe and effective in CKD of all stages, making it the most
appropriate choice.
Q7. Which of the following best describes the pathophysiology of Type 1
Diabetes Mellitus?
A. Peripheral insulin resistance with relative insulin deficiency
B. Autoimmune destruction of pancreatic beta cells leading to absolute insulin
deficiency
C. Excessive glucagon secretion from pancreatic alpha cells
D. Downregulation of insulin receptors due to chronic hyperinsulinemia
E. Impaired incretin secretion from intestinal L-cells
