Patient Care Fundamentals Flashcards

A patient's blood pressure is 148/92 mmHg. Which position should the LVN place the patient in before retaking the reading?

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.

When transferring a patient from bed to wheelchair, the LVN should lock the wheelchair wheels and place it at what angle to the bed?

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.

A patient is ordered to be on a low-Fowler's position. The head of the bed should be elevated to how many degrees?

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.

The LVN notes a patient's radial pulse is irregular. What is the most appropriate next action?

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.

Which oxygen delivery device provides the highest and most precise concentration of oxygen?

Answer: Venturi mask

The Venturi mask delivers a precise, controlled oxygen concentration, making it ideal for patients requiring specific FiO2 levels.

A patient with a nasogastric tube reports nausea. The LVN should first:

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.

When performing passive range-of-motion exercises, the LVN should move each joint to the point of:

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.
