Question 1

What water temperature should a CNA use when giving a patient a bed bath?

Accepted Answer

Water should be between 105°F and 110°F (40.5°C–43.3°C). The CNA should always test the temperature with a thermometer or the inner wrist before applying water to the patient.

Question 2

In what order should a CNA wash a patient's body during a complete bed bath?

Accepted Answer

Wash from cleanest to dirtiest areas: face first, then neck, arms, chest, abdomen, legs, back, and perineal area last. This prevents spreading microorganisms from dirty to clean areas.

Question 3

Why should a CNA change the basin water during a bed bath?

Accepted Answer

The water must be changed when it becomes cool, soapy, or dirty—especially before washing the perineal area—to prevent cross-contamination and maintain patient comfort and hygiene.

Question 4

When giving a back rub, which areas should the CNA avoid?

Accepted Answer

The CNA should avoid rubbing bony prominences (such as the spine and shoulder blades) and any areas of redness, broken skin, or rash, as friction can worsen skin breakdown.

Question 5

How should a CNA position a patient who cannot stand for a shower?

Accepted Answer

The patient should be seated in a shower chair or shower wheelchair to maintain safety and stability. The CNA must ensure the chair is secured and non-slip mats are in place to prevent falls.
