Correct answers in bold green with:
● Physiological mechanism explanations
● Clinical manifestation correlations
● Treatment protocol rationales
● Complication prevention strategies
Critical Updates 2025/2026
● NEW – IV fluid selection guidelines (crystalloid vs. colloid)
● UPDATED – Electrolyte replacement protocols (IV vs. PO thresholds)
● REVISED – ABG interpretation methods (stepwise approach)
● MODIFIED – Patient safety monitoring parameters (telemetry, hourly I&O)
Fluid Balance & Imbalances (Q1–Q20)
1. A client with heart failure has 3+ pitting edema, dyspnea, and JVD. Which
fluid imbalance is present?
a) Fluid volume deficit
b) Fluid volume excess (hypervolemia)
c) Third-spacing
d) Dehydration
Rationale: Classic signs of fluid overload due to impaired cardiac pumping.
Complication: Pulmonary edema → respiratory failure.
2. Daily weight change of 2.2 lb equals how many mL of fluid?
a) 500 mL
b) 1000 mL
c) 1500 mL
d) 2200 mL
Rationale: 1 kg = 1 L = 2.2 lb.
