ABSTRACT
This study document brings together 141 carefully worded exam questions drawn from Galen NSG
4100 Adult Health III Exam and Correct Answers with Rationales New 2026-2027 Update, with the
strongest emphasis placed on Prioritize nursing interventions for patients with complex,
multisystem health alterations using evidence-based guidelines, Analyze hemodynamic, laboratory,
and diagnostic data to guide clinical decision-making in acute and critical care settings and
Evaluate the safety and efficacy of pharmacologic and nonpharmacologic treatments for adult
health conditions. 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 PRIORITIZE NURSING INTERVENTIONS FOR PATIENTS WITH COMPLEX, MULTISYSTEM
HEALTH ALTERATIONS USING EVIDENCE-BASED GUIDELINES
A patient with acute decompensated heart failure is receiving continuous IV
furosemide. Which assessment finding most urgently indicates a need to hold the
diuretic and notify the provider?
A. Serum potassium 3.1 mEq/L with new U waves on ECG CORRECT
B. Urine output 100 mL/hr for the past 2 hours
C. Blood pressure 98/60 mm Hg with dizziness upon standing
D. Serum sodium 134 mEq/L and BUN 28 mg/dL
RATIONALE: Hypokalemia (K+ <3.5) with U waves increases risk for lethal dysrhythmias,
especially with concurrent digoxin or QT-prolonging drugs; this warrants holding the diuretic and
immediate provider notification. The other findings are either expected effects of diuresis or less
immediately life-threatening.
Q2 PRIORITIZE NURSING INTERVENTIONS FOR PATIENTS WITH COMPLEX, MULTISYSTEM
HEALTH ALTERATIONS USING EVIDENCE-BASED GUIDELINES
A patient with a new tracheostomy is being weaned from mechanical ventilation.
Which parameter best indicates readiness for extubation?
A. Positive end-expiratory pressure (PEEP) of 5 cm H2O
B. Rapid shallow breathing index (RSBI) of 80 breaths/min/L CORRECT
C. PaO2/FiO2 ratio of 150
D. Minute ventilation of 12 L/min
RATIONALE: An RSBI <105 breaths/min/L predicts successful weaning; 80 indicates readiness.
PEEP of 5 alone is not sufficient, PaO2/FiO2 of 150 indicates severe impairment, and minute
ventilation >10 L/min may indicate increased work of breathing or dead space.

,Q3 PRIORITIZE NURSING INTERVENTIONS FOR PATIENTS WITH COMPLEX, MULTISYSTEM
HEALTH ALTERATIONS USING EVIDENCE-BASED GUIDELINES
A patient with acute ischemic stroke is admitted 4 hours after symptom onset.
Which intervention is contraindicated?
A. Administering IV alteplase if CT shows no hemorrhage
B. Maintaining blood pressure <185/110 mm Hg before thrombolysis
C. Giving aspirin 325 mg PO immediately CORRECT
D. Performing a bedside swallow screen before oral intake
RATIONALE: Aspirin is contraindicated within 24 hours of IV thrombolysis due to increased
bleeding risk. Alteplase is indicated if no hemorrhage, BP control is required before thrombolysis,
and swallow screening prevents aspiration.
Q4 PRIORITIZE NURSING INTERVENTIONS FOR PATIENTS WITH COMPLEX, MULTISYSTEM
HEALTH ALTERATIONS USING EVIDENCE-BASED GUIDELINES
A patient with diabetic ketoacidosis (DKA) has a blood glucose of 480 mg/dL, pH
7.22, and bicarbonate 12 mEq/L. After initiating IV fluids and insulin, which
laboratory value should the nurse monitor most closely to prevent a complication?
A. Serum potassium CORRECT
B. Serum sodium
C. Serum chloride
D. Serum magnesium
RATIONALE: Insulin drives potassium intracellularly, causing life-threatening hypokalemia;
potassium must be monitored closely and replaced as needed. Sodium, chloride, and
magnesium are less acutely dangerous in DKA management.

, Q5 PRIORITIZE NURSING INTERVENTIONS FOR PATIENTS WITH COMPLEX, MULTISYSTEM
HEALTH ALTERATIONS USING EVIDENCE-BASED GUIDELINES
A patient with acute kidney injury (AKI) has a serum potassium of 6.8 mEq/L and
peaked T waves. Which intervention should the nurse anticipate as the priority?
A. Administering sodium polystyrene sulfonate (Kayexalate) orally
B. Initiating hemodialysis
C. Administering IV calcium gluconate CORRECT
D. Infusing regular insulin with dextrose
RATIONALE: IV calcium gluconate is the priority to stabilize cardiac membranes and prevent
lethal dysrhythmias when ECG changes are present. Other measures (insulin/dextrose,
Kayexalate, dialysis) lower potassium but do not immediately protect the heart.
Q6 PRIORITIZE NURSING INTERVENTIONS FOR PATIENTS WITH COMPLEX, MULTISYSTEM
HEALTH ALTERATIONS USING EVIDENCE-BASED GUIDELINES
A patient with cirrhosis and portal hypertension is admitted with hematemesis.
Which medication should the nurse expect to administer to reduce portal
pressure?
A. Propranolol
B. Octreotide CORRECT
C. Lactulose
D. Spironolactone
RATIONALE: Octreotide is a somatostatin analog that reduces splanchnic blood flow and portal
pressure in acute variceal bleeding. Propranolol is for prophylaxis, lactulose treats
encephalopathy, and spironolactone manages ascites.
