A PCT presses on a patient's ankle and leaves a pit about 4 mm deep that fades within roughly 15 seconds. On a commonly used scale, how is this edema graded?

2+ pitting edema. On a common 1+ to 4+ scale, a pit of about 4 mm that rebounds within roughly 10 to 15 seconds is graded 2+. About 2 mm with quick rebound is 1+, about 6 mm is 3+, and about 8 mm lasting several minutes is 4+. Any new or worsening edema, especially swelling in only one calf, should be reported to the nurse.

A PCT writes the wrong blood pressure on a paper flowsheet. What is the correct way to fix it?

Draw a single line through the entry so it stays readable, write 'error,' and add initials with the date and time before writing the correct value. A charting error on paper is corrected with a single line through the mistake so it remains legible, the word 'error' or 'mistaken entry,' and the writer's initials plus the date and time. Erasing, correction fluid, and rewriting pages obscure the original entry, which can look like falsification in a legal review.

Which abbreviation appears on The Joint Commission's official Do Not Use list?

QD. The Joint Commission's Do Not Use list includes U, IU, Q.D. (QD), Q.O.D., trailing zeros, missing leading zeros, MS, MSO4, and MgSO4, because each has caused medication errors. QD has been misread as QID (four times daily); the safe alternative is to write 'daily.' BP, NPO, and PRN are common approved abbreviations.

A patient's vital signs are taken at 7:45 p.m. How should the time be documented in 24-hour format?

To convert afternoon and evening times to the 24-hour clock, add 12 to the hour, so 7:45 p.m. becomes 1945. 0745 would mean 7:45 a.m. Using 24-hour time prevents a.m. and p.m. mix-ups in the medical record.

Recognizing, Reporting & Documenting Changes in Condition

Two related NCCT tasks carry heavy weight in the Patient Intake and Care category: report changes in the patient's condition (for example, level of consciousness or blood pressure) and document medically relevant aspects of patient care in the patient record. PCTs spend more time at the bedside than anyone else, so they are often the first to notice that a patient "just isn't right." A delay between noticing and reporting is one of the most common links in the chain that ends in a preventable cardiac arrest.

Level of Consciousness and Orientation

AVPU scale: Alert, responds to Voice, responds only to Pain, Unresponsive. Any drop from the patient's baseline is reported immediately.
Orientation: ask the patient to state who they are, where they are, the date or time, and why they are in the hospital (person, place, time, situation). Record, for example, "oriented to person and place, not to time."
New confusion is never "just old age." Sudden confusion or agitation can signal low oxygen, low blood sugar, infection, stroke, or medication effects. Delirium develops over hours to days and fluctuates, while dementia is long-standing. Compare with the documented baseline and report any change.

Skin Changes Worth Reporting

NCCT lists bruising and edema as examples of skin-integrity changes the PCT identifies and reports:

Bruising: describe the location, size in centimeters, color, and pattern. Unexplained or patterned bruises may point to injury or abuse (see Section 14.2), and new bruising in a patient on anticoagulants may signal bleeding.
Edema: check dependent areas (feet, ankles, sacrum in bedbound patients). Press a finger on the skin for a few seconds and watch how deep the dent is and how long it lasts. One commonly used scale:

Grade	Approximate Pit Depth	Rebound
1+	About 2 mm	Disappears quickly
2+	About 4 mm	Fades within about 10–15 seconds
3+	About 6 mm	Lasts up to a minute or longer
4+	About 8 mm	Lasts several minutes

Swelling, warmth, and pain in one calf can mean a deep vein thrombosis and is reported at once. Rapid weight gain in a heart-failure patient (see Section 4.5) is reported as well.

What to Report Immediately

Category	Examples
Vital signs	Any value outside the parameters the nurse gave you, or a big change from baseline
Breathing	Shortness of breath, noisy or labored breathing, SpO2 below the ordered range
Heart and circulation	Chest pain or pressure, new irregular pulse, cold or blue extremities
Neurologic	New confusion, drowsiness, BE-FAST stroke signs, seizure
Bleeding and output	Bleeding from any site, black or bloody stool, coffee-ground emesis, urine output below 30 mL per hour
Safety events	Falls, injuries, a patient pulling out tubes, threats of self-harm
Pain and comfort	New or worsening pain, pain unrelieved after treatment
Intake	Refusing meals or fluids, vomiting, choking on food

Report using SBAR (Situation, Background, Assessment, Recommendation; see Section 3.1). Tell the nurse face to face or by phone for urgent findings; a note in the chart is not a report.

Objective and Subjective Data

Objective data are what you observe or measure: "BP 88/50 mm Hg, skin pale and clammy."
Subjective data are what the patient tells you, recorded in their own words: Patient states, "I feel like I'm going to pass out."
Avoid opinions and labels such as "uncooperative" or "drunk." Describe the behavior instead: "Patient pushed the meal tray away and said, 'Leave me alone.'"

Documentation Rules the NCPCT Tests

Timely: chart as soon as possible after giving care, never before. Charting a task in advance is falsification.
Accurate and objective: write only what you saw, did, or measured, and use exact numbers.
Your own care only: never document for a coworker or under someone else's login.
Complete: include the date, time, what was done, the patient's response, and who was notified.
Legible and permanent: on paper, use ink; in the electronic health record (EHR), follow the system's workflow.
Correcting errors: on paper, draw a single line through the mistake so it remains readable, write "error" or "mistaken entry," then add your initials and the date and time. Never erase, use correction fluid, or scribble over it. In the EHR, correct entries through the system's amendment process, which keeps the original visible in the audit trail.
Late entries: label them clearly as late entries, with the current date and time plus the time the care actually happened.
Approved abbreviations only. The Joint Commission's Do Not Use list includes:

Do Not Use	Write Instead
U, u	"unit"
IU	"International Unit"
Q.D., QD, q.d. / Q.O.D., QOD	"daily" / "every other day"
Trailing zero (5.0 mg)	5 mg
Missing leading zero (.5 mg)	0.5 mg
MS, MSO4, MgSO4	"morphine sulfate" or "magnesium sulfate"

24-Hour (Military) Time

Healthcare records use the 24-hour clock to prevent a.m./p.m. errors. Morning hours stay the same (8:15 a.m. = 0815). For afternoon and evening hours, add 12: 1:00 p.m. = 1300 and 7:45 p.m. = 1945. Midnight is 0000 (some facilities write 2400 for the end of a day), and 12:30 a.m. is 0030.

Clinical Trap: Charting Instead of Reporting

At 0600 a PCT finds a patient's blood pressure at 82/48, well below the parameter the nurse gave. The PCT enters it in the flowsheet and moves on to the next room, assuming the nurse will see it. The value sits unread for an hour. Documentation does not replace notification: tell the nurse right away, then document the value, the time, and the name of the nurse you told.
