6.1 Bathing, Perineal Care & Bed Baths

Bathing is not only a fundamental hygiene task but also a vital therapeutic intervention in nursing assistant practice. In Oregon, Certified Nursing Assistants (CNAs) perform bathing to promote physical cleanliness, stimulate cutaneous circulation, prevent skin breakdown, and enhance the resident's psychological well-being. A bath provides the CNA with a prime opportunity to perform a comprehensive head-to-toe skin inspection, which is critical for early detection of pressure injuries or circulatory changes. The CNA must understand the different types of baths, the exact sequencing of procedures, the safety limits of water temperature, and the specific clinical guidelines for perineal care to pass the Headmaster/TMU state skills evaluation.

Types of Baths

CNAs encounter three primary types of bathing in Oregon long-term care facilities:

1. Complete Bed Bath: This is performed for residents who are totally bedridden, comatose, or otherwise unable to assist with their own hygiene. The CNA washes the resident's entire body while they remain in bed.
2. Partial Bed Bath: A partial bath focuses only on areas that cause odor or discomfort if left unwashed: the face, hands, underarms (axillae), back, and the perineal area. This is typically performed on days when a complete bath or shower is not scheduled to maintain hygiene without drying out the resident's skin.
3. Tub Bath or Shower: For residents who are ambulatory or can sit safely in a shower chair. Shower chairs and tub lifts must be locked in place. The CNA must ensure the shower room is warm, draft-free, and that non-slip mats are used. A safety belt should be secured if the resident uses a shower chair, and the resident must never be left unattended in the shower or tub under any circumstances.

Water Temperature and Safety

Water temperature control is a paramount safety responsibility for the CNA. The skin of elderly residents is often thin, fragile, and less sensitive to heat, making them highly susceptible to burns. The safe water temperature range for bathing and showering is between 105°F and 110°F (40.5°C to 43.3°C). To verify safety, the CNA must:

• Fill the basin or test the shower spray.
• Check the water temperature using a bath thermometer or by testing it on the inside of their own wrist (where skin is thin and sensitive).
• Oregon TMU/Headmaster testing point: The CNA must always ask the resident to verify the water temperature for comfort before applying any water to the resident's body. The CNA can say, "Would you please feel this water to make sure it is comfortable for you?"

Step-by-Step Complete Bed Bath Sequence

When performing a complete bed bath, the CNA must follow a strict clean-to-dirty sequence to prevent the spread of microorganisms. The general order is from the cleanest parts of the body to the dirtiest parts:

1. Preparation: Wash hands, gather all supplies (soap, basin, washcloths, bath towels, bath blanket, clean gown/clothes, gloves), explain the procedure, and pull the privacy curtain. Raise the bed to a comfortable working height and lower the side rail on the working side. Cover the resident with a bath blanket and fold down the top covers to preserve dignity and warmth.
2. Eyes and Face (Cleanest): Wipe the resident's eyes first. Wet a washcloth without soap. Wipe from the inner canthus (inside corner) to the outer canthus to prevent spreading pathogens into the tear duct. Use a different, clean area of the washcloth for the other eye. Wash the rest of the face, neck, and ears. Soap is generally omitted on the face unless requested by the resident, as it can be drying. Pat dry with a towel.
3. Arms and Hands: Place a bath towel under the arm furthest from you to protect the bed linens. Wash the arm from the wrist up to the shoulder (distal to proximal). Washing in this direction promotes venous blood flow back to the heart. Wash the hand and clean under the fingernails. Repeat for the arm closest to you.
4. Chest and Abdomen: Fold the bath blanket down to the resident's waist. Place a towel over the chest. Lift the towel slightly to wash, rinse, and dry the chest and under the breasts (a common site for moisture-associated skin damage or fungal infections). Wash the abdomen, paying attention to the umbilicus. Pat all areas dry.
5. Legs and Feet: Expose one leg at a time. Place a towel under the leg. Wash from the ankle to the hip (distal to proximal). Wash the foot, thoroughly cleaning between the toes. Rinse and dry the spaces between the toes completely to prevent skin maceration and fungal infections (like tinea pedis). Repeat for the other leg.
6. Back: Assist the resident to turn onto their side (lateral position) facing away from you. Place a towel along the back. Wash from the neck down to the lower back and buttocks. This is an excellent time to inspect the coccyx and sacrum for redness or skin breakdown. Apply lotion and perform a back massage if desired.
7. Perineal Area (Dirtiest): Turn the resident back onto their back and perform perineal care last.

Perineal Care Clinical Guidelines

Perineal care involves cleaning the genital and anal areas. It requires gloves, clean water, and strict adherence to infection control principles.

• The "Clean-to-Dirty" Principle: Always wipe from front-to-back (anterior to posterior). For both male and female residents, wiping from front-to-back prevents introducing fecal bacteria (such as Escherichia coli) into the urethra, which is the primary cause of Urinary Tract Infections (UTIs).
• Washcloth Sectioning: The CNA must use a clean section of the washcloth for each single downward stroke. Fold the washcloth into quarters and flip to a clean panel or use a new washcloth for each wipe.
• Female Perineal Care: Separate the labia majora. Wipe down one side of the labia from front-to-back. Flip the washcloth and wipe down the opposite side from front-to-back. Change the cloth surface and wipe down the center (meatus and vaginal opening) from front-to-back. Rinse in the same sequence and pat dry thoroughly.
• Male Perineal Care: Wash the penis starting at the meatus (tip) and wiping downward toward the base.
  • Retractable Foreskin Safety: If the male resident is uncircumcised, the CNA must gently retract the foreskin to clean the glans penis. Wash in a circular motion from the meatus outward. Rinse the glans, and immediately return the foreskin to its natural position. Failure to pull the foreskin back down can lead to paraphimosis, a painful emergency where the retracted foreskin constricts the glans penis and cuts off blood flow. Wash the shaft, scrotum (including the underside), and perineum.
• Anal Area: Assist the resident to turn on their side. Clean from the perineum back toward the anus. Wipe from front-to-back, using a clean cloth surface for each stroke. Rinse and pat dry. Remove soiled linens, change water if it becomes soapy or cool, remove gloves, wash hands, and apply fresh gloves to dress the resident.
