Patient Direct Care (1–40)
1. A 68-year-old woman with chronic heart failure presents with worsening
dyspnea. Which pharmacologic class should the CNS prioritize for rapid symptom
control?
A) Beta-blockers
B) Loop diuretics
C) Calcium channel blockers
D) ACE inhibitors
Answer: B
Rationale: Loop diuretics (e.g., furosemide) reduce preload and pulmonary
congestion, providing rapid relief of dyspnea in heart failure exacerbations. Beta-
blockers and ACE inhibitors are for long-term management, not acute symptom
control .
2. In advanced health assessment, which laboratory value is most indicative of
acute myocardial infarction?
A) Elevated serum potassium
B) Elevated troponin I/T levels
C) Decreased hemoglobin
D) Elevated B-type natriuretic peptide (BNP)
,Answer: B
Rationale: Cardiac troponin I and T are highly specific and sensitive biomarkers for
myocardial injury, rising within hours of an infarction. BNP is elevated in heart
failure, not specific for MI .
3. A 45-year-old male with chronic obstructive pulmonary disease (COPD)
presents with increased dyspnea and a PaO₂ of 58 mmHg on room air. Which
oxygen delivery device provides the most precise FiO₂ for this patient?
A) Nasal cannula at 2 L/min
B) Simple face mask at 10 L/min
C) Non-rebreather mask at 15 L/min
D) Venturi mask set at 35% FiO₂
Answer: D
Rationale: Venturi masks deliver a calibrated, precise FiO₂, which is essential for
COPD patients at risk for CO₂ retention. Nasal cannula FiO₂ varies with respiratory
pattern .
4. Which of the following is the most appropriate nursing diagnosis for a patient
with acute pain related to a postoperative incision?
A) Risk for infection
B) Acute pain
C) Impaired physical mobility
D) Ineffective coping
Answer: B
Rationale: "Acute pain" directly addresses the patient's reported pain related to
the surgical incision. This is a direct, accurate nursing diagnosis for the immediate
postoperative period .
,5. A patient with end-stage renal disease is scheduled for hemodialysis. Which
medication should the CNS monitor closely for potential accumulation?
A) Metoprolol
B) Furosemide
C) Gabapentin
D) Albuterol
Answer: C
Rationale: Gabapentin is primarily renally excreted and can accumulate in patients
with impaired kidney function, requiring dose adjustment. Metoprolol is
hepatically metabolized; furosemide has active metabolites that may accumulate
but is less concerning than gabapentin .
6. When interpreting an arterial blood gas (ABG) showing pH 7.30, PaCO₂ 55
mmHg, HCO₃⁻ 28 mEq/L, the CNS should recognize the primary disorder as:
A) Metabolic acidosis
B) Respiratory alkalosis
C) Respiratory acidosis with metabolic compensation
D) Metabolic alkalosis
Answer: C
Rationale: Elevated PaCO₂ (>45) indicates respiratory acidosis. The mildly elevated
HCO₃⁻ (normal 22–26) shows partial metabolic compensation. The pH remains
acidic (<7.35) .
7. In advanced health assessment, which finding is most concerning for possible
diabetic ketoacidosis (DKA)?
A) Blood glucose 180 mg/dL
B) Serum ketones positive and anion gap 18 mEq/L
C) Hemoglobin A1c 7.2%
D) Blood pH 7.38
, Answer: B
*Rationale: DKA is characterized by hyperglycemia, ketosis, and an elevated anion
gap metabolic acidosis (anion gap >12). Blood glucose is typically >250 mg/dL, and
pH is <7.30. Anion gap 18 with positive ketones is highly concerning .*
8. A patient is admitted with acute pancreatitis. Which laboratory finding is most
specific for this diagnosis?
A) Elevated amylase
B) Elevated lipase
C) Elevated ALT
D) Elevated alkaline phosphatase
Answer: B
Rationale: Lipase is more sensitive and specific for acute pancreatitis than
amylase. It remains elevated longer and is not produced by salivary glands, which
can confound amylase readings. Amylase can be elevated in many non-pancreatic
conditions .
9. Which pharmacokinetic principle explains why a drug with a high volume of
distribution may require a larger loading dose?
A) Increased renal clearance
B) Extensive tissue binding
C) Short half-life
D) Low protein binding
Answer: B
Rationale: A high volume of distribution indicates extensive tissue binding,
necessitating a larger loading dose to achieve therapeutic plasma concentrations.
The drug is distributed into tissues, leaving less in the vascular space .
