PN NCLEX Practice Questions
Question 1 of 5.
Extract:Laboratory Results Glucose - Fasting 70 - 110 mg/dL (3.9 - 6.1 mmol/L) 650 mg/dL (36.1 mmol/L)
A nurse is caring for 4 clients. Which prescription by the health care provider would the nurse question and seek further clarification before administering?
A. 0.45% sodium chloride solution for a client with severe gastroenteritis who had 12 episodes of diarrhea and vomiting in the past 4 hours
B. IV bolus of 1000 mL 0.9% sodium chloride solution for a client in anaphylaxis due to a food allergy
C. IV bolus of 1000 mL 0.9% sodium chloride solution for a client with diabetic ketoacidosis who has a serum glucose level of 650 mg/dL (36.1 mmol/L)
D. IV mannitol 25% solution for a client with a closed head injury who is exhibiting signs of increased intracranial pressure
Explanation: 0.45% saline is appropriate for gastroenteritis to replace fluids. 0.9% saline bolus treats anaphylactic shock. Mannitol reduces intracranial pressure. A 1000 mL bolus for DKA is excessive; smaller boluses (e.g., 250-500 mL) are safer to avoid fluid overload.
Question 2 of 5.
A woman who is at 39 weeks gestation enters the hospital in early labor. Several hours later, she says, 'What's happening? I suddenly feel as though I have to have a bowel movement.' The woman starts bearing down as if to push out stool. What is the best initial action for the licensed practical nurse at this time?
A. Encourage her to push
B. Ask her to pant
C. Immediately call the charge nurse
D. Ask her when she last had a bowel movement
Explanation: The urge to have a bowel movement and bearing down indicate advanced labor or delivery. Panting prevents pushing, allowing time to assess and prepare for delivery.
Question 3 of 5.
The nurse is caring for an adult male who is receiving haloperidol (Haldol). Which complaint by the client is of most concern to the nurse and should be immediately reported?

B. I am having trouble getting an erection.
C. My legs are cramping and I feel like I need to walk all the time.
