A patient in the intensive care unit with a diagnosis of septic shock has a mean arterial
pressure (MAP) of 58 mm Hg despite fluid resuscitation of 30 mL/kg crystalloid. Current
medications include norepinephrine at 12 mcg/min and vasopressin at 0.04 units/min. The
patient's serum lactate is 4.2 mmol/L and central venous oxygen saturation (ScvO2) is
62%. Which hemodynamic parameter is most critical to assess next to guide further
therapy?
A. Pulmonary artery wedge pressure (PAWP)
(Correct) B. Cardiac index (CI)
C. Systemic vascular resistance (SVR)
D. Stroke volume variation (SVV)
Correct Answer: B
In septic shock with persistent hypotension and elevated lactate, assessing cardiac index helps determine if the
low MAP is due to low cardiac output or low SVR. A low CI would suggest need for inotropic support (e.g.,
dobutamine), while normal/high CI would indicate vasopressor adjustment. PAWP is less dynamic; SVR can be
calculated; SVV requires mechanical ventilation with specific conditions.

Question: 2 of 200
A patient with a history of chronic kidney disease (stage 4) and type 2 diabetes mellitus is admitted for
hyperkalemia (serum potassium 6.8 mEq/L). ECG shows peaked T waves. The provider orders intravenous
A. Sodium polystyrene sulfonate (Kayexalate) orally

A patient with a history of chronic kidney disease (stage 4) and type 2 diabetes mellitus is
admitted for hyperkalemia (serum potassium 6.8 mEq/L). ECG shows peaked T waves. The
provider orders intravenous calcium gluconate, regular insulin 10 units IV with 50 mL of
50% dextrose, and albuterol nebulized. Which additional intervention should the nurse
anticipate to achieve sustained potassium reduction?
A. Sodium polystyrene sulfonate (Kayexalate) orally
(Correct) B. Hemodialysis
C. Furosemide 40 mg IV
D. Sodium bicarbonate 50 mEq IV
Correct Answer: B
In stage 4 CKD with severe hyperkalemia, the most effective and sustained method to remove potassium is
hemodialysis. Sodium polystyrene sulfonate is slow and carries risk of intestinal necrosis; furosemide may be
ineffective with low GFR; sodium bicarbonate is less potent and may cause fluid overload.

Question: 3 of 200
A patient on a medical-surgical unit develops sudden onset of dyspnea, pleuritic chest pain, and hemoptysis.
Vital signs: BP 100/60, HR 110, RR 28, SpO2 88% on room air. The nurse suspects pulmonary embolism.
A. Administer enoxaparin 1 mg/kg subcutaneously
B. Obtain a CT pulmonary angiogram (CTPA)
C. Start intravenous unfractionated heparin per protocol
D. Prepare for thrombolytic therapy

A patient on a medical-surgical unit develops sudden onset of dyspnea, pleuritic chest
pain, and hemoptysis. Vital signs: BP 100/60, HR 110, RR 28, SpO2 88% on room air. The
nurse suspects pulmonary embolism. After applying oxygen and establishing IV access,
which action should the nurse perform next?
A. Administer enoxaparin 1 mg/kg subcutaneously
B. Obtain a CT pulmonary angiogram (CTPA)
(Correct) C. Start intravenous unfractionated heparin per protocol
D. Prepare for thrombolytic therapy
Correct Answer: C
For a patient with high-probability PE and no contraindications, immediate anticoagulation with IV
unfractionated heparin is indicated before diagnostic confirmation if delay is expected. Enoxaparin is acceptable
but IV heparin allows rapid reversal if needed. CTPA is diagnostic but should not delay treatment. Thrombolytics
are reserved for massive PE with hemodynamic instability.

A patient in the emergency department presents with acute onset of confusion, ataxia, and
nystagmus. The patient has a history of alcohol use disorder. Serum osmolality is 340
mOsm/kg, and an osmolal gap of 40 mOsm/kg is calculated. Which toxic alcohol ingestion
is most consistent with these findings?
(Correct) A. Methanol
B. Ethylene glycol
C. Isopropyl alcohol
D. Ethanol
Correct Answer: A
Methanol ingestion causes an elevated osmolal gap and presents with visual disturbances, confusion, and
ataxia. Ethylene glycol also causes elevated gap but typically with oxalate crystals and renal failure; isopropyl
alcohol causes ketosis without acidosis; ethanol causes intoxication but not typically the triad of confusion,
ataxia, nystagmus.
