PSB-PN Patient Care & Clinical Skills 3

Question 1

The practical nurse is preparing to apply a sequential compression device (SCD) to a post-operative patient. The PRIMARY purpose of SCDs is to:

Accepted Answer

Prevent deep vein thrombosis (DVT)

Answer

SCDs apply intermittent pneumatic compression to the lower extremities to prevent venous stasis and reduce the risk of deep vein thrombosis.

Question 2

A practical nurse is collecting a urine specimen for a mid-stream clean-catch culture. What is the CORRECT sequence of steps?

Accepted Answer

Cleanse the meatus, discard the first stream, collect the mid-stream

Answer

Cleansing the meatus and discarding the initial stream flushes urethral contaminants so the mid-stream sample represents true bladder urine.

Question 3

A patient has a left-sided weakness from a stroke and needs to use a cane. Where should the cane be held?

Accepted Answer

In the right (stronger) hand

Answer

Holding the cane in the stronger hand allows it to bear weight when the weaker leg steps forward, improving stability and gait.

Question 4

When caring for a patient in contact isolation, the practical nurse should remove personal protective equipment (PPE) in which order?

Accepted Answer

Gloves → gown → mask → hand hygiene

Answer

CDC doffing guidelines specify removing gloves first (most contaminated), then gown, then mask, finishing with hand hygiene to prevent self-contamination.

Question 5

A practical nurse is performing tracheostomy care. How should the inner cannula be cleaned?

Accepted Answer

Soak in hydrogen peroxide, then rinse with normal saline

Answer

Soaking the inner cannula in half-strength hydrogen peroxide loosens secretions, and rinsing with normal saline removes any residue before reinsertion.
