Question 1: A 78-year-old patient with hypertension, diabetes, and chronic kidney disease
presents to the acute care unit with sudden onset confusion, slurred speech, and right-sided
facial droop. Which diagnostic test should the Adult-Gerontology Acute Care Nurse
Practitioner prioritize to confirm the suspected diagnosis?
A. Complete blood count with differential
B. Non-contrast computed tomography of the head
C. Electrocardiogram with rhythm strip
D. Serum troponin I level
CORRECT ANSWER: B. Non-contrast computed tomography of the head
RATIONALE: The clinical presentation is highly suggestive of acute ischemic stroke. Non-contrast
CT head is the initial imaging modality of choice to rapidly differentiate ischemic from
hemorrhagic stroke, which is critical for determining eligibility for thrombolytic therapy. While
other tests may be indicated for comprehensive evaluation, CT head provides the most time-
sensitive diagnostic information for acute neurological deficits.
Question 2: When assessing an adult-gerontology patient with suspected acute coronary
syndrome, which finding would most strongly indicate the need for immediate reperfusion
therapy?
A. ST-segment depression in two contiguous leads
B. Elevated troponin I with normal ECG
C. New left bundle branch block with chest pain
D. T-wave inversion in anterior leads
CORRECT ANSWER: C. New left bundle branch block with chest pain
RATIONALE: A new or presumably new left bundle branch block in the setting of acute chest
pain is considered a STEMI equivalent per ACC/AHA guidelines and warrants immediate
activation of the cardiac catheterization laboratory for potential percutaneous coronary
,intervention. ST depression and T-wave inversion suggest ischemia but not necessarily STEMI,
while elevated troponin with normal ECG may indicate NSTEMI requiring urgent but not
emergent reperfusion.
Question 3: An 82-year-old patient with sepsis secondary to pneumonia is receiving
norepinephrine for vasopressor support. Which assessment finding indicates the medication
is achieving its therapeutic goal?
A. Heart rate decreased from 128 to 98 beats per minute
B. Mean arterial pressure increased from 58 to 68 mmHg
C. Urine output increased from 15 to 45 mL/hr
D. Lactate level decreased from 4.2 to 2.8 mmol/L
CORRECT ANSWER: B. Mean arterial pressure increased from 58 to 68 mmHg
RATIONALE: Norepinephrine is a potent alpha-adrenergic agonist used primarily to increase
systemic vascular resistance and raise mean arterial pressure (MAP) in distributive shock. The
target MAP for most septic patients is ≥65 mmHg to ensure adequate organ perfusion. While
improved urine output and decreasing lactate are positive indicators of resolving shock, they are
downstream effects; the direct therapeutic goal of norepinephrine is MAP restoration.
Question 4: A patient with acute exacerbation of chronic obstructive pulmonary disease
presents with respiratory distress, pH 7.28, PaCO2 68 mmHg, and PaO2 52 mmHg on room air.
Which intervention should the AGACNP implement first?
A. Administer intravenous methylprednisolone
B. Initiate non-invasive positive pressure ventilation
C. Start nebulized albuterol and ipratropium
D. Obtain arterial blood gas repeat in 30 minutes
CORRECT ANSWER: B. Initiate non-invasive positive pressure ventilation
RATIONALE: The arterial blood gas reveals acute hypercapnic respiratory failure with respiratory
acidosis. Non-invasive positive pressure ventilation (NIPPV) is the first-line intervention for acute
hypercapnic respiratory failure in COPD exacerbation, as it reduces work of breathing, improves
gas exchange, and decreases the need for intubation. Bronchodilators and steroids are
important adjuncts but do not address the immediate ventilatory failure.
Question 5: Which laboratory finding is most consistent with acute kidney injury secondary to
prerenal azotemia in an elderly patient with heart failure?
A. Urine sodium >40 mEq/L with fractional excretion of sodium >2%
B. Urine sodium <20 mEq/L with fractional excretion of sodium <1%
,C. Presence of granular casts on urinalysis
D. Urine osmolality <300 mOsm/kg
CORRECT ANSWER: B. Urine sodium <20 mEq/L with fractional excretion of sodium <1%
RATIONALE: Prerenal azotemia results from decreased renal perfusion with intact tubular
function, leading to avid sodium and water reabsorption. This manifests as low urine sodium
(<20 mEq/L), low FeNa (<1%), and high urine osmolality (>500 mOsm/kg). Elevated urine
sodium and FeNa suggest intrinsic renal injury, while granular casts indicate acute tubular
necrosis.
Question 6: An adult-gerontology patient receiving vancomycin for MRSA bacteremia has a
trough level of 22 mcg/mL drawn 30 minutes before the next scheduled dose. What is the
most appropriate action for the AGACNP?
A. Continue current dosing regimen
B. Increase the dosing interval
C. Administer the next dose as scheduled
D. Hold the dose and recheck level in 6 hours
CORRECT ANSWER: B. Increase the dosing interval
RATIONALE: The target vancomycin trough for serious MRSA infections is 15-20 mcg/mL. A
trough of 22 mcg/mL exceeds the therapeutic range and increases risk of nephrotoxicity and
ototoxicity. Increasing the dosing interval allows drug levels to decline into the therapeutic
range while maintaining efficacy. Holding the dose without adjusting the regimen may lead to
subtherapeutic levels upon reinitiation.
Question 7: Which clinical finding most strongly suggests compartment syndrome in a patient
with a tibial fracture?
A. Pallor and decreased pedal pulses
B. Pain out of proportion to injury with passive stretch
C. Paresthesia in the affected extremity
D. Paralysis of the affected limb
CORRECT ANSWER: B. Pain out of proportion to injury with passive stretch
RATIONALE: Pain out of proportion to injury, particularly with passive stretching of muscles
within the compartment, is the earliest and most sensitive indicator of compartment syndrome.
Pallor, pulselessness, paresthesia, and paralysis are late findings indicating irreversible ischemic
damage. Early recognition based on disproportionate pain allows for timely fasciotomy to
prevent permanent disability.
, Question 8: A 76-year-old patient with atrial fibrillation on warfarin presents with melena and
hemoglobin drop from 12.4 to 8.9 g/dL. INR is 4.8. Which intervention should be prioritized?
A. Administer intravenous vitamin K 10 mg
B. Transfuse 2 units packed red blood cells
C. Administer 4-factor prothrombin complex concentrate
D. Hold warfarin and repeat INR in 6 hours
CORRECT ANSWER: C. Administer 4-factor prothrombin complex concentrate
RATIONALE: In life-threatening bleeding with supratherapeutic INR, 4-factor prothrombin
complex concentrate (PCC) provides rapid reversal of warfarin anticoagulation by replenishing
vitamin K-dependent clotting factors. PCC acts within minutes, whereas vitamin K requires 6-24
hours for effect. Blood transfusion addresses anemia but does not correct coagulopathy.
Holding warfarin alone is insufficient for active bleeding.
Question 9: Which assessment finding indicates successful weaning from mechanical
ventilation in an adult-gerontology patient?
A. Rapid shallow breathing index of 95 breaths/min/L
B. Negative inspiratory force of -18 cm H2O
C. Tidal volume of 4 mL/kg predicted body weight
D. Minute ventilation of 12 L/min
CORRECT ANSWER: A. Rapid shallow breathing index of 95 breaths/min/L
RATIONALE: The rapid shallow breathing index (RSBI = respiratory rate/tidal volume in liters) is a
validated predictor of weaning success. An RSBI <105 breaths/min/L suggests adequate
respiratory muscle strength and lung mechanics for spontaneous breathing. Negative inspiratory
force should be ≤-20 to -30 cm H2O, tidal volume should be ≥5 mL/kg, and minute ventilation
should be <10 L/min for successful weaning.
Question 10: A patient with diabetic ketoacidosis has initial serum potassium of 3.2 mEq/L.
Which intervention is most critical before initiating insulin therapy?
A. Administer intravenous potassium chloride
B. Start continuous insulin infusion at 0.1 units/kg/hr
C. Administer intravenous sodium bicarbonate
D. Obtain stat serum magnesium level
CORRECT ANSWER: A. Administer intravenous potassium chloride
RATIONALE: Insulin drives potassium intracellularly, which can precipitate life-threatening
hypokalemia in patients with already low serum potassium. Potassium repletion to ≥3.3 mEq/L
