PSB-PN Patient Care & Clinical Skills

Question 1

When performing a bed bath for a patient, the practical nurse should wash in which order to prevent cross-contamination?

Accepted Answer

Face first, then move downward toward the feet

Answer

Clean-to-dirty technique requires washing the face first and progressing downward to the perineal area to prevent spreading microorganisms.

Question 2

A practical nurse is preparing to take a patient's blood pressure. Which site is the standard first-choice location for this measurement?

Accepted Answer

Brachial artery in the upper arm

Answer

The brachial artery in the upper arm is the standard site for blood pressure measurement because it is at heart level and easily accessible.

Question 3

Which position is MOST appropriate for a patient experiencing difficulty breathing (dyspnea)?

Accepted Answer

High Fowler's (head of bed elevated 60–90°)

Answer

High Fowler's position uses gravity to lower the diaphragm and expand lung capacity, reducing the work of breathing.

Question 4

A practical nurse is using a pulse oximeter. A reading of 94% SpO2 in an otherwise healthy adult is considered:

Accepted Answer

Borderline low — monitor closely and notify the nurse

Answer

Normal SpO2 is 95–100%; a reading of 94% is borderline low and warrants close monitoring and notification of the supervising nurse.

Question 5

When measuring a patient's urinary output, the practical nurse should record the amount in which unit?

Accepted Answer

Milliliters (mL)

Answer

Urinary output is measured and documented in milliliters (mL) as part of accurate intake-and-output (I&O) monitoring.
