10.2 Acute Illness, Infection & Recognizing a Change in Condition

Acute Illness, Infection & Recognizing a Change in Condition

Chronic disease sets the baseline. Acute change is what happens on top of it, and catching it early is arguably the highest-value thing a nursing assistant does. Residents who deteriorate quietly for two shifts go to the hospital; residents whose change is caught within hours often stay home.

1. Why Older Residents Present Atypically

The textbook infection picture — high fever, shaking chills, a sharp localized complaint — depends on a vigorous immune response and a reliable ability to describe symptoms. Older residents frequently have neither.

+-----------------------------------------------------------------------------+
|            WHY THE CLASSIC SIGNS GO MISSING IN OLDER RESIDENTS              |
|                                                                             |
|   [BLUNTED FEVER]  ---> A weaker immune response means an infected resident |
|                         may run only 99.5 F, or even become HYPOTHERMIC.    |
|                         An elevation of ~2 degrees over that resident's     |
|                         own baseline matters more than any fixed number.    |
|   [REDUCED PAIN]   ---> Neuropathy and altered pain perception mute the     |
|                         classic localized complaint.                        |
|   [COMMUNICATION]  ---> Dementia, aphasia, or hearing loss may prevent the  |
|                         resident from reporting anything at all.            |
|   [POLYPHARMACY]   ---> Medications mask fever, slow the pulse, and blunt   |
|                         the body's warning signals.                         |
|                                                                             |
|   RESULT: the FIRST sign of infection in an older adult is very often       |
|   SUDDEN CONFUSION, A FALL, or simply "not acting like themselves."         |

[!IMPORTANT] "She's just not herself today" is a clinical finding, not small talk. You know your residents' baselines better than the nurse does. When a normally chatty resident goes quiet, a continent resident wets the bed, or a steady walker suddenly staggers, that observation belongs in the nurse's hands within minutes — not at the end of the shift.

2. The Infections That Actually Occur in Long-Term Care

[!WARNING] The alcohol-gel exception is a guaranteed exam point. Alcohol-based hand rub is the preferred routine method, but it does not kill C. difficile spores or norovirus. When caring for a resident with diarrhea of unknown cause or a confirmed C. diff infection, wash with soap and running water — the mechanical friction physically washes spores down the drain.

3. Change-of-Condition Observations: The Reporting List

Learn this as a list, because Data Collection and Disease Process questions both draw from it.

Report immediately — do not wait

• Any acute change in mental status: new confusion, disorientation, unusual drowsiness, or agitation
• Chest pain, pressure, or tightness; pain radiating to the jaw, neck, or arm
• Difficulty breathing, gasping, noisy or labored breathing, or cyanosis of lips or nail beds
• Stroke signs (BE FAST): balance, eyes, face, arms, speech
• Any fall, whether or not the resident appears injured
• Bleeding that does not stop, or vomiting blood or coffee-ground material
• A temperature elevated about 2 degrees above that resident's baseline, or a new hypothermia
• Seizure activity
• A resident who cannot be roused, or whose level of consciousness has dropped
• New or severe pain, or a resident who was comfortable and now is not

Report before the end of your shift

• New or worsening edema, or a weight change of 2 to 3 pounds in a day
• Changes in appetite or fluid intake, refusal of meals, or new coughing while eating
• Changes in urine: color, odor, clarity, amount, burning, new incontinence
• Changes in bowel pattern: diarrhea, no bowel movement in three days, black or bloody stool
• New skin findings: redness that does not blanch, a blister, a tear, a bruise, a rash, or drainage
• New complaints of dizziness, weakness, numbness, or tingling
• Changes in mood or behavior: withdrawal, tearfulness, new refusal of care, new aggression
• Any device problem: a hearing aid that stopped working, a prosthesis that no longer fits, oxygen tubing damage

4. How to Report: Objective, Specific, Immediate

Vague reports get vague responses. Compare:

Quote what the resident said in their own words, give numbers wherever you have them, and state the resident's baseline so the nurse can see the size of the change. Then document what you observed and what you reported, to whom, and when.

[!TIP] Report first, chart second, and never chart what you have not yet reported. Charting is a record; reporting is an intervention. A perfectly written note about a resident's chest pain that sits in a chart for two hours has helped nobody.

5. The Boundaries That Frame This Whole Subject Area

Disease Process questions frequently test scope of practice through a clinical scenario. Anchor yourself with these:

• A CNA observes and reports; the nurse assesses. Never write or say that you "assessed" a resident.
• A CNA never diagnoses, never names a condition to a resident or family, and never speculates aloud about what is wrong.
• A CNA never administers medication, including over-the-counter remedies, ointments, and a family member's cough drops.
• A CNA never adjusts oxygen flow rates, changes a sterile dressing, performs sterile procedures, or inserts or removes tubes.
• A CNA stays with a resident in distress and calls for help rather than leaving to find someone.
