1. A patient with a STEMI receives tPA and suddenly develops a severe headache
r r r r r r r r r r r r r




r and vomiting. BP 200/110 mmHg. What is the nurse's immediate action?
r r r r r r r r r r




A. Administer antiemetic r




B. Notify provider and prepare for emergency CT scan
r r r r r r r




C. Lower head of bed r r r




D. Give acetaminophen
r

,Answer: B. These are classic signs of intracranial hemorrhage, a life-threatening
r r r r r r r r r r




r complication of tPA. Rapid imaging and neurosurgical consultation are critical

r .

2. A patient with sepsis has a lactate of 5.2 mmol/L and BP 82/48 mmHg after 30
r r r r r r r r r r r r r r r r




mL/kg crystalloid. What is the next priority?
r r r r r r r




A. Start dopamine r




B. Begin norepinephrine to maintain MAP ≥ 65 mmHg
r r r r r r r




C. Obtain CT scan r r




D. Administer antibiotics r




Answer: B. Fluid-refractory septic shock requires vasopressor
r r r r r r




r support. Norepinephrine is first-line per Surviving Sepsis Guidelines
r r r r r r r 1 r .

3. A patient post-craniotomy has a sudden decrease in LOC and blown pupil. What
r r r r r r r r r r r r r




r is the nurse's first action?
r r r r




A. Obtain CT order r r




B. Raise head of bed 30° and hyperventilate
r r r r r r




C. Give mannitol r




D. Call family r




Answer: B. This indicates increased ICP. The priority is to elevate HOB and
r r r r r r r r r r r r




r hyperventilate to reduce PaCO₂, which causes vasoconstriction and decreases r r r r r r r r




r ICP 1 r .

4. A patient with DKA has K⁺ 2.8 mEq/L after insulin infusion. What is the priority intervention?
r r r r r r r r r r r r r r r r




A. Continue insulin r




B. Give 40 mEq KCl IV per protocol
r r r r r r




C. Start phosphate r




D. Stop fluids r




Answer: B. Hypokalemia must be corrected before insulin administration to
r r r r r r r r r




r prevent fatal dysrhythmias, as insulin drives potassium into cells
r r r r r r r r 1 r .

5. A nurse is caring for a client who is receiving heparin therapy and has an aPTT of
r r r r r r r r r r r r r r r r r




92 seconds (control 30). Which medication should the nurse anticipate?
r r r r r r r r r r




A. Leucovorin
B. Vitamin K r

, C. Deferoxamine
D. Protamine

Answer: D. An aPTT > 3x control requires intervention. Protamine sulfate is the
r r r r r r r r r r r r




r specific antagonist for heparin
r r r 3 r .

6.A patient with a subdural hematoma has ICP 18 mmHg and BP 90/60 mmHg. What
r r r r r r r r r r r r r r r




r is the priority?
r r




A. Give mannitol r




B. Increase BP to maintain cerebral perfusion pressure (CPP ≥ 60 mmHg)
r r r r r r r r r r




C. Lower head of bed r r r




D. Hyperventilate rapidly r




Answer: B. CPP = MAP - ICP. A low MAP reduces CPP, potentially causing brain
r r r r r r r r r r r r r r




r ischemia. Fluids or vasopressors may be needed
r r r r r r 1 r .

7. A nurse is assessing a client who is 1 day postoperative following open ileostomy
r r r r r r r r r r r r r r




placement. Which finding is the priority to report?
r r r r r r r r




A. Liquid fecal drainage from stoma r r r r




B. Absence of bowel sounds r r r




C. Stoma is dark purple in color r r r r r




D. Client reports pain at the surgical site
r r r r r r




Answer: C. A dark purple or black stoma indicates ischemia or necrosis of
r r r r r r r r r r r r




r the bowel, requiring immediate surgical intervention
r r r r r 9 r .

8.A patient with a GI bleed has BP 78/40 mmHg and HR 130 bpm.What is the
r r r r r r r r r r r r r r r r r




priority?
r




A. Insert NG tube r r




B. Start 2 large-bore IVs and give rapid crystalloid
r r r r r r r




C. Obtain type and cross r r r




D. Give pantoprazole r




Answer: B. Hemodynamic instability from hemorrhagic shock requires
r r r r r r r




r immediate fluid resuscitation and blood preparation r r r r r 1 r .

9. A patient with a spinal cord injury at T4 has BP 80/50 mmHg and HR 48 bpm.
