CMSRN Trivia 2 — Questions and Answers
Question 1: Which laboratory value is the best indicator of a patient's nutritional status over the past 3 weeks?
- Albumin (Correct answer)
- Prealbumin
- Transferrin
- Total protein
Correct answer: Albumin
Albumin has a half-life of approximately 20 days, making it the best marker of nutritional status over a 3-week period.
Question 2: A patient is prescribed heparin infusion. Which antidote should the nurse have readily available?
- Vitamin K
- Protamine sulfate (Correct answer)
- Phytonadione
- Fresh frozen plasma
Correct answer: Protamine sulfate
Protamine sulfate is the specific antidote for heparin overdose, neutralizing its anticoagulant effect.
Question 3: What is the most common site for a pulmonary embolism to originate?
- Upper extremity veins
- Pelvic veins
- Deep veins of the lower extremities (Correct answer)
- Renal veins
Correct answer: Deep veins of the lower extremities
The majority of pulmonary emboli originate from deep vein thromboses in the lower extremities.
Question 4: Which Glasgow Coma Scale score indicates severe brain injury?
- 13-15
- 9-12
- 6-8
- 3-8 (Correct answer)
Correct answer: 3-8
A GCS score of 3-8 indicates severe brain injury and is commonly associated with coma.
Question 5: A patient with chronic kidney disease has a serum potassium of 6.2 mEq/L. Which ECG change is the nurse most likely to observe first?
- Widened QRS complex
- Peaked T waves (Correct answer)
- Flattened P waves
- Sine wave pattern
Correct answer: Peaked T waves
Peaked T waves are the earliest ECG manifestation of hyperkalemia, preceding more dangerous changes.
Question 6: Which type of wound healing occurs when a wound closes by granulation tissue filling a large tissue defect?
- Primary intention
- Secondary intention (Correct answer)
- Tertiary intention
- Delayed primary closure
Correct answer: Secondary intention
Secondary intention healing occurs when wound edges are not approximated, and the wound fills with granulation tissue from the bottom up.
Question 7: A patient receiving a blood transfusion develops a fever, chills, and back pain within 15 minutes. The nurse's priority action is to:
- Administer antipyretics and slow the infusion
- Stop the transfusion and maintain IV access with normal saline (Correct answer)
- Obtain a urine specimen and continue monitoring
- Notify the physician before stopping the transfusion
Correct answer: Stop the transfusion and maintain IV access with normal saline
Stopping the transfusion immediately and maintaining IV access is the priority action when a hemolytic transfusion reaction is suspected.
