1. A 68-year-old male with a history of heart failure presents with acute dyspnea, bilateral crackles,
and an S3 gallop. Laboratory results show an elevated B-type natriuretic peptide (BNP) level of
1,200 pg/mL. Which of the following pharmacological interventions should the nurse anticipate
initiating first to reduce preload?
A. Intravenous furosemide
B. Oral metoprolol succinate
C. Subcutaneous enoxaparin
D. Intravenous digoxin
, CORRECT ANSWER : A
Rationale: Intravenous loop diuretics such as furosemide are the mainstay of acute
decompensated heart failure management to rapidly reduce volume overload and decrease
cardiac preload. Metoprolol is a beta-blocker used for chronic maintenance therapy and could
worsen acute decompensation if initiated during acute fluid overload. Enoxaparin is an
anticoagulant for thromboembolism prophylaxis, and digoxin is reserved for rate control or
persistent symptoms, neither addressing acute preload reduction.
2. A patient in the intensive care unit is receiving mechanical ventilation. Arterial blood gas results
show pH 7.31, PaCO2 55 mmHg, HCO3 24 mEq/L, and PaO2 65 mmHg. How should the
clinician interpret these findings?
A. Metabolic alkalosis with hypoxemia
B. Acute respiratory acidosis with hypoxemia
C. Chronic respiratory alkalosis with normal oxygenation
D. Mixed metabolic and respiratory acidosis without hypoxemia
CORRECT ANSWER : B
Rationale: The low pH (7.31) indicates acidemia, and the elevated PaCO2 (55 mmHg) points to
a primary respiratory cause due to alveolar hypoventilation. The bicarbonate level is within the
normal range, confirming an acute presentation without renal compensation. The PaO2 of 65
mmHg clearly indicates hypoxemia, making acute respiratory acidosis with hypoxemia the
correct interpretation.
3. An advanced practice nurse is evaluating a patient with newly diagnosed type 2 diabetes mellitus
and persistent microalbuminuria. Which class of medication provides the primary renal-
protective benefit beyond glycemic control?
A. Calcium channel blockers
B. Thiazide diuretics
C. Angiotensin-converting enzyme inhibitors
D. Beta-adrenergic blockers
CORRECT ANSWER : C
Rationale: Angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers
(ARBs) are recommended for patients with diabetes and microalbuminuria because they reduce
intraglomerular pressure and slow the progression of diabetic nephropathy. Calcium channel
, blockers and beta-blockers do not offer the same targeted hemodynamic protection to the renal
efferent arterioles. Thiazides are primarily used for hypertension and volume management
rather than primary nephroprotection.
4. A patient scheduled for an elective surgical procedure expresses reluctance to receive a blood
transfusion due to religious beliefs, despite a high risk of intraoperative hemorrhage. What is the
most appropriate ethical and legal course of action?
A. Override the patient's refusal due to the immediate threat to life during surgery.
B. Respect the competent adult's right to refuse treatment after informed consent.
C. Require a court order to proceed with the surgery without blood products.
D. Cancel the elective surgery permanently without further discussion.
CORRECT ANSWER : B
Rationale: A mentally competent adult patient has the legal and ethical right to refuse any
medical treatment, including life-saving blood transfusions, based on the principle of autonomy.
Healthcare providers must honor this refusal provided the patient is fully informed of the risks.
Overriding the refusal or forcing a court order without extraordinary legal grounds violates
patient self-determination.
5. A nurse leader is implementing a new evidence-based protocol for fall prevention. Which
framework is most appropriate for evaluating the outcomes and sustainability of this practice
change?
A. PICO model
B. PDSA cycle
C. SWOT analysis
D. Maslow's hierarchy
CORRECT ANSWER : B
Rationale: The Plan-Do-Study-Act (PDSA) cycle is a systematic quality improvement model
widely used to test, evaluate, and sustain clinical practice changes in healthcare settings. The
PICO model is used to frame clinical research questions rather than evaluate implementation.
SWOT analysis evaluates strategic business factors, and Maslow's hierarchy addresses human
psychological and physical needs.
, 6. A 55-year-old female presents with crushing subrosternal chest pain radiating to the left arm,
diaphoresis, and ST-segment elevation in leads II, III, and aVF on a 12-lead ECG. 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
CORRECT ANSWER : C
Rationale: ST-segment elevation in leads II, III, and aVF indicates an inferior wall myocardial
infarction, which is typically supplied by the right coronary artery (RCA). The left anterior
descending artery supplies the anterior wall, the left circumflex supplies the lateral wall, and
occlusion of the left main coronary artery typically causes extensive anterolateral ischemia.
7. A patient with severe sepsis is receiving aggressive fluid resuscitation with normal saline.
Current vital signs show blood pressure 82/48 mmHg, heart rate 125 beats/min, and central
venous pressure 14 mmHg, with persistent oliguria and mottled extremities. Which intervention
is indicated next?
A. Administer an additional 500 mL bolus of normal saline
B. Initiate an infusion of norepinephrine
C. Discontinue all fluid administration immediately
D. Administer a loop diuretic for oliguria
CORRECT ANSWER : B
Rationale: In septic shock refractory to initial fluid resuscitation (evidenced by a high CVP and
persistent hypotension), vasopressor therapy with norepinephrine is indicated to restore
adequate mean arterial pressure and organ perfusion. Further fluid boluses could worsen fluid
overload and increase myocardial strain, while diuretics would be harmful in hypoperfused
states.
8. An interprofessional team is managing a patient with chronic obstructive pulmonary disease
(COPD) experiencing an acute exacerbation. Which arterial blood gas value warrants immediate
clinical concern for impending respiratory failure?
A. pH 7.35 with PaCO2 45 mmHg
