CNA Skills and Competencies

Question 1

Which clinical skill is considered a core competency that all CNAs must demonstrate during their certification exam?

Accepted Answer

Hand hygiene (handwashing technique)

Answer

Hand hygiene is a universal core competency tested on every CNA certification exam. It is the foundational infection control practice and is evaluated during the clinical skills portion to ensure all CNAs perform it correctly before, during, and after patient care.

Question 2

A CNA is performing a two-person transfer. What is each person's primary role?

Accepted Answer

One CNA supports the upper body/head and the other controls the lower body, coordinating movements together

Answer

In a two-person transfer, one CNA supports and guides the resident's upper body and head while the second CNA controls the lower body. Both must communicate clearly, count together before lifting, and use proper body mechanics to protect both themselves and the resident.

Question 3

How should a CNA measure a resident's blood pressure using a manual sphygmomanometer?

Accepted Answer

Place the cuff 1 inch above the elbow, inflate 20–30 mmHg above palpated systolic, deflate slowly at 2–3 mmHg/sec

Answer

To measure blood pressure manually, the CNA places the cuff 1 inch above the antecubital space, palpates the brachial artery, inflates 20–30 mmHg above the palpated systolic pressure, then deflates slowly at 2–3 mmHg per second while listening with a stethoscope for Korotkoff sounds.

Question 4

What is the correct site for measuring an axillary temperature?

Accepted Answer

In the center of the underarm (axilla) with the arm held close to the body

Answer

An axillary (underarm) temperature is taken by placing the thermometer probe in the center of the armpit (axilla), ensuring the arm is held close to the body. It is considered the least accurate route but is used when oral or rectal routes are not appropriate.

Question 5

When performing range of motion (ROM) exercises, how should the CNA move each joint?

Accepted Answer

Slowly and gently, supporting above and below the joint, stopping at the point of resistance

Answer

ROM exercises should be performed slowly and gently through the full available range of motion. The CNA should support the joint above and below, move only to the point of resistance or slight discomfort, and never force a joint beyond its natural range, as this could cause injury.
