13.1 Data Collection Overview

13.1 Data Collection Overview

Data Collection is the part of the State Tested Nurse Aide (STNA) role where you gather facts about a resident's condition: vital signs, fluid intake and urine output, height and weight, and direct observations. On the Ohio written examination administered by Headmaster / D&S Diversified Technologies, this material falls under the basic-nursing-skills category and contributes roughly 6% of the 79 multiple-choice questions. The exam gives you 90 minutes, and you must reach 70% to pass the written portion.

Scope of practice: collect and record, do not interpret

The single biggest rule in this chapter: a nurse aide measures, observes, and records data, then reports anything abnormal to the licensed nurse. You never diagnose, never decide that a fever is unimportant, and never adjust a care plan on your own. If a blood pressure reads 190/100 or a resident says "my chest hurts," your job is to record the value and tell the nurse immediately, not to evaluate the cause.

Normal adult ranges to memorize

These numbers reappear across the whole exam, so commit them to memory cold. A reading even slightly outside the range is not yours to judge; you record the exact number and notify the nurse.

Objective versus subjective data

• Objective data is something you can measure or see: a pulse of 88, a reddened heel, an untouched lunch tray, 200 mL of urine in the commode.
• Subjective data is what the resident tells you and you cannot directly verify: "I feel dizzy," "my hip aches," "I am nauseous."

Record subjective statements in the resident's own words inside quotation marks when possible. Both types matter, but the exam loves to test whether you can tell them apart and whether you record fact rather than opinion.

Worked example

A resident is served an 8 oz (240 mL) cup of juice and drinks half. You measure half the cup. The objective intake recorded is 120 mL (4 oz multiplied by 30 mL/oz). The resident also says "this juice is too sour" - that is subjective and is not part of the intake total. Keep the measured number and the quoted complaint clearly separate.

Common trap

A familiar distractor invites you to act on the data yourself: "give the resident extra fluids," "hold the next meal," or "reassure the resident the reading is fine." Those answers cross your scope. The correct choice almost always pairs accurate recording with prompt reporting to the nurse.

Why accurate data matters

The numbers you collect are the foundation of the whole care plan. The nurse compares today's blood pressure to yesterday's, the dietitian watches the intake totals, and the physician decides on medication changes based on the weight trend you charted. If your reading is wrong because you used the thumb to count a pulse, or you guessed a urine volume rather than measuring it, the entire chain of decisions is built on bad information. The exam treats sloppy data collection as a patient-safety problem, not a clerical one.

Consider a resident with congestive heart failure. A two- to three-pound weight gain over a day or two can mean the body is retaining fluid, an early warning the nurse needs before the resident becomes short of breath. You will not be asked to know the diagnosis, but you must know that the right response to that weight change is to report it promptly. The same logic applies to a dropping oxygen saturation, a falling urine output, or a new complaint of pain.

When and how often to measure

Vital signs are typically taken on admission, at routine intervals set by the care plan, before and after certain procedures, and any time a resident's condition appears to change. If a resident looks pale, complains of feeling unwell, or has a fall, you take a fresh set of vital signs and report them. Routine intake and output is tracked across the full 24-hour day and totaled at the end of each shift, which is why intake and output sheets use the 24-hour clock (for example, 1400 instead of 2:00 p.m.) so entries from day and night shifts line up without a.m./p.m. confusion.

Recording versus reporting

Keep these two verbs distinct, because the exam does. Recording means writing the data on the flow sheet or in the electronic record - every measurement gets recorded. Reporting means telling the nurse out loud, right away - only abnormal or changed findings get reported (in addition to being recorded). A normal pulse of 72 is recorded and needs no report. A pulse of 48 is recorded AND reported. Memorize that all data is recorded but only the abnormal or new is also reported.
