1. What is the primary reason for performing regular neurovascular
assessments in patients with traumatic injuries?
A. To prevent blood clots
B. To monitor for signs of hemorrhage
C. To detect early signs of neurovascular compromise
D. To assess the need for surgical intervention
Answer: c) To detect early signs of neurovascular compromise
Rationale: Regular neurovascular assessments help detect changes in
circulation, motor function, and sensation, which could indicate
compromise in the affected area. Early detection allows for timely
interventions to prevent further damage.
2. A nurse is caring for a patient who has just had a stroke. Which of the
following interventions should the nurse prioritize?
,A. Encourage the patient to drink fluids frequently
B. Perform frequent neurovascular assessments
C. Administer thrombolytics within the first hour
D. Keep the patient in a flat, supine position
Answer: b) Perform frequent neurovascular assessments
Rationale: Monitoring for neurological changes is crucial in stroke
patients, as this helps detect any deterioration in their condition and
allows for timely interventions.
3. What is a common cause of hypoglycemia in critically ill patients?
A. Excessive intake of carbohydrates
B. Administration of insulin or other hypoglycemic agents
C. Sepsis or infection
D. Renal failure
Answer: b) Administration of insulin or other hypoglycemic agents
,Rationale: In critically ill patients, insulin therapy or other hypoglycemic
agents can cause hypoglycemia, especially if dosing is not carefully
monitored.
4. Which of the following interventions is most effective for preventing
venous thromboembolism (VTE) in critically ill patients?
A. Bed rest with limited movement
B. Administration of low-molecular-weight heparin
C. Frequent blood pressure monitoring
D. Elevating the legs above heart level
Answer: b) Administration of low-molecular-weight heparin
Rationale: Low-molecular-weight heparin (LMWH) is commonly used
to prevent VTE by inhibiting clot formation, especially in critically ill
patients who are immobile.
5. Which of the following is a primary concern for a patient receiving
total parenteral nutrition (TPN)?
, A. Hyperglycemia
B. Hyperkalemia
C. Respiratory acidosis
D. Hemorrhagic shock
Answer: a) Hyperglycemia
Rationale: TPN provides a high concentration of glucose, which can lead
to hyperglycemia. Close monitoring of blood glucose levels is essential
in patients receiving TPN.
6. Which of the following is a key consideration when managing fluid
balance in a critically ill patient?
A. Administering large amounts of fluids to prevent dehydration
B. Closely monitoring input and output
C. Limiting fluids to avoid hypervolemia
D. Avoiding diuretics unless absolutely necessary
Answer: b) Closely monitoring input and output
assessments in patients with traumatic injuries?
A. To prevent blood clots
B. To monitor for signs of hemorrhage
C. To detect early signs of neurovascular compromise
D. To assess the need for surgical intervention
Answer: c) To detect early signs of neurovascular compromise
