ABSTRACT
This study document brings together 49 carefully worded exam questions drawn from NSG 4100
(AH III) Exam and Correct Answers plus Rationales New Update 2026-2027 Galen, with the
strongest emphasis placed on Interpret invasive hemodynamic and ventilator data to guide titration
of therapy in complex adult patients, Prioritize nursing interventions using current evidence-based
guidelines for multisystem critical illness, Evaluate provider prescriptions for safety, indication and
and contraindication in high-acuity scenarios. Every item follows the wording style and level of
reasoning you meet in the real paper, and each one is paired with a clear rationale so the correct
choice is never a guess. Work through the set at your own pace, mark the questions that slow you
down, then come back to them until the reasoning feels automatic. Learners who revise this way
walk into the exam room recognising the pattern behind the questions instead of meeting them for
the first time. Keep going - steady, honest practice is what turns a difficult paper into a comfortable
pass.

,Q1 INTERPRET INVASIVE HEMODYNAMIC AND VENTILATOR DATA TO GUIDE TITRATION OF
THERAPY IN COMPLEX ADULT PATIENTS
A patient in septic shock has received 30 mL/kg crystalloid and is now on
norepinephrine 12 mcg/min. MAP is 58 mm Hg, CVP 14 mm Hg, ScvO2 62%, lactate
rising. Which intervention best matches current Surviving Sepsis Campaign
guidance?
A. Administer 1 L additional crystalloid bolus
B. Add vasopressin 0.03 units/min CORRECT
C. Start dobutamine 5 mcg/kg/min
D. Transfuse 1 unit PRBCs
RATIONALE: When MAP remains below 65 mm Hg despite high-dose norepinephrine and
adequate fluid resuscitation, vasopressin is added to achieve vasoconstriction via V1 receptors
and reduce catecholamine requirements. Additional fluid is unlikely to help with CVP already
elevated and may worsen pulmonary edema. Dobutamine is not first-line for MAP; transfusion is
only indicated for Hb <7 g/dL without ischemia.
Q2 INTERPRET INVASIVE HEMODYNAMIC AND VENTILATOR DATA TO GUIDE TITRATION OF
THERAPY IN COMPLEX ADULT PATIENTS
A patient with ARDS on volume-control ventilation: VT 6 mL/kg PBW, PEEP 18 cm
H2O, plateau pressure 32 cm H2O, driving pressure 14 cm H2O, SpO2 88%. Which
action is most consistent with lung-protective ventilation evidence?
A. Increase VT to 8 mL/kg PBW
B. Decrease PEEP to 10 cm H2O
C. Perform recruitment maneuver
D. Prone position for 16 hours CORRECT
RATIONALE: Prone positioning improves oxygenation and reduces mortality in moderate-severe
ARDS (PaO2/FiO2 <150) by reducing ventral alveolar overdistension and dorsal atelectasis.
Increasing VT or decreasing PEEP would worsen hypoxemia or atelectrauma. Recruitment
maneuvers are not routinely recommended due to risk of barotrauma and hemodynamic
compromise.

, Q3 INTERPRET INVASIVE HEMODYNAMIC AND VENTILATOR DATA TO GUIDE TITRATION OF
THERAPY IN COMPLEX ADULT PATIENTS
A patient with acute ischemic stroke has BP 210/110 mm Hg and is being
evaluated for IV thrombolysis. Which blood pressure management is correct per
current AHA/ASA guidelines?
A. Lower BP to <185/110 mm Hg before thrombolysis CORRECT
B. Withhold thrombolysis due to hypertension
C. Lower BP by 25% in first hour
D. Administer nitroprusside for rapid reduction
RATIONALE: IV thrombolysis requires BP <185/110 mm Hg; labetalol or nicardipine is used to
achieve this. Withholding thrombolysis solely for hypertension is inappropriate if BP can be
controlled. Rapid reduction or nitroprusside is avoided due to risk of cerebral hypoperfusion and
toxicity.
Q4 INTERPRET INVASIVE HEMODYNAMIC AND VENTILATOR DATA TO GUIDE TITRATION OF
THERAPY IN COMPLEX ADULT PATIENTS
A patient with DKA has glucose 480 mg/dL, pH 7.12, HCO3 8 mEq/L, K+ 3.2 mEq/L,
and is on an insulin infusion. Which prescription should the nurse question?
A. 0.9% NaCl with 20 mEq KCl/L at 200 mL/hr
B. Insulin infusion at 0.1 units/kg/hr
C. Sodium bicarbonate 100 mEq IV bolus CORRECT
D. Fingerstick glucose every hour
RATIONALE: Bicarbonate is not routinely recommended in DKA unless pH <6.9 due to risks of
hypokalemia, paradoxical CSF acidosis, and cerebral edema. Potassium replacement is
essential as insulin drives K+ intracellularly. Hourly glucose monitoring and insulin infusion are
standard.
