LVN Patient Care Fundamentals 2 — Questions and Answers
Question 1: A patient's blood pressure is 148/92 mmHg. Which position should the LVN place the patient in before retaking the reading?
- Supine with legs elevated
- Sitting with feet flat on the floor for 5 minutes (Correct answer)
- Left lateral Sims' position
- Standing upright
Correct answer: Sitting with feet flat on the floor for 5 minutes
The patient should rest in a sitting position with feet flat for at least 5 minutes before an accurate blood pressure measurement is taken.
Question 2: When transferring a patient from bed to wheelchair, the LVN should lock the wheelchair wheels and place it at what angle to the bed?
- 90 degrees
- 180 degrees
- 45 degrees (Correct answer)
- Parallel to the bed
Correct answer: 45 degrees
The wheelchair is placed at a 45-degree angle to the bed to minimize the distance and pivot needed during the transfer.
Question 3: A patient is ordered to be on a low-Fowler's position. The head of the bed should be elevated to how many degrees?
- 15 to 30 degrees (Correct answer)
- 45 to 60 degrees
- 60 to 90 degrees
- 90 degrees
Correct answer: 15 to 30 degrees
Low-Fowler's position elevates the head of the bed 15 to 30 degrees, used for patients who cannot tolerate higher elevations.
Question 4: The LVN notes a patient's radial pulse is irregular. What is the most appropriate next action?
- Document and continue routine care
- Take an apical pulse for a full 60 seconds (Correct answer)
- Administer oxygen immediately
- Recheck the pulse in 30 minutes
Correct answer: Take an apical pulse for a full 60 seconds
An irregular radial pulse requires assessment of the apical pulse for a full minute to accurately determine heart rate and rhythm.
Question 5: Which oxygen delivery device provides the highest and most precise concentration of oxygen?
- Nasal cannula
- Simple face mask
- Venturi mask (Correct answer)
- Non-rebreather mask
Correct answer: Venturi mask
The Venturi mask delivers a precise, controlled oxygen concentration, making it ideal for patients requiring specific FiO2 levels.
Question 6: A patient with a nasogastric tube reports nausea. The LVN should first:
- Administer an antiemetic
- Check NG tube placement and patency (Correct answer)
- Remove the NG tube
- Elevate the head of the bed to 90 degrees
Correct answer: Check NG tube placement and patency
Before any intervention, the LVN must verify NG tube placement and ensure it is patent, as displacement can cause nausea.
Question 7: When performing passive range-of-motion exercises, the LVN should move each joint to the point of:
- Pain and beyond
- Slight resistance
- Maximum extension only
- Resistance, then stop (Correct answer)
Correct answer: Resistance, then stop
Passive ROM exercises should be performed to the point of resistance and then stopped to avoid injury to the patient's joints.
