,Q1. A patient with acute respiratory distress syndrome (ARDS) is on volume-controlled ventilation
with FiO2 0.8, PEEP 10 cm H2O, and plateau pressure 28 cm H2O. The nurse notes a sudden drop
in SpO2 from 92% to 84% and an increase in peak inspiratory pressure (PIP) from 30 to 40 cm
H2O. What is the nurse's priority action?
A. Suction the endotracheal tube
B. Increase FiO2 to 1.0
C. Decrease PEEP to 5 cm H2O
D. Administer a neuromuscular blocking agent
Correct Answer: A. Suction the endotracheal tube
Rationale: A sudden increase in PIP with a drop in SpO2 suggests an acute airway obstruction (e.g.,
mucus plug) or tube occlusion. Suctioning is the priority to restore patency. Increasing FiO2 may
temporarily improve oxygenation but does not address the underlying obstruction. Decreasing PEEP
could worsen oxygenation and alveolar collapse. Neuromuscular blockade is not first-line for acute
desaturation with high PIP.
Why Wrong:
B - Increasing FiO2 does not address the likely cause of obstruction and may delay definitive airway
management.
C - Decreasing PEEP can lead to alveolar derecruitment and worsen hypoxemia in ARDS.
D - Neuromuscular blockade is used for patient-ventilator dyssynchrony or severe hypoxemia
refractory to other measures, not as first response to acute desaturation with high PIP.

Management, 9th Ed., Ch. 14.
Q2. A patient with chronic kidney disease stage 4 (eGFR 25 mL/min/1.73 m²) is admitted with
hyperkalemia (K+ 6.8 mEq/L) and ECG changes (peaked T waves). The provider orders
intravenous calcium gluconate, regular insulin with dextrose 50%, and albuterol nebulization.
Which action should the nurse question?
A. Administer calcium gluconate over 10 minutes
B. Give regular insulin 10 units IV push followed by dextrose 50% 50 mL
C. Administer albuterol nebulization 10 mg
D. Obtain a stat serum potassium level after interventions
Correct Answer: C. Administer albuterol nebulization 10 mg
Rationale: Albuterol nebulization for hyperkalemia is typically given at a dose of 10-20 mg, but in
patients with CKD, high-dose albuterol can cause tachycardia and hypokalemia, and its efficacy is
reduced. More importantly, the standard dose is 10-20 mg, but the order for 10 mg is acceptable;
however, the nurse should question the route (nebulization) because IV albuterol is more effective and
preferred in severe hyperkalemia. Many protocols use IV albuterol (0.5 mg) instead of nebulization.
However, the key point is that calcium gluconate is given first for cardiac protection, insulin + dextrose is
standard, and potassium recheck is necessary. The questionable order is the albuterol dose/route; IV
albuterol is preferred in this setting.
Why Wrong:
A - Calcium gluconate given slowly over 10 minutes is correct to stabilize the cardiac membrane.
B - Regular insulin 10 units IV with dextrose 50% is standard for shifting potassium intracellularly.
D - Rechecking potassium after interventions is essential to assess response and guide further
treatment.
