CCMA Normal Lab Values & Vital Signs: High-Yield Ranges to Memorize
High-yield CCMA vital signs and lab reference ranges with MA first actions: adult and pediatric vitals, CBC, glucose, potassium, lipids, INR, and UA.
By MedCertPrep Team · Updated August 4, 2026
This guide is a high-yield memory card for adult vital signs and common lab reference ranges used in NHA CCMA prep. It is written for candidates who already know the exam map and need fast recall of in-range vs out-of-range values, plus the first MA action when a result is abnormal. For domain weights and Clinical Patient Care subdomains, use the CCMA study guide. For a calendar, use the CCMA study plan. For method, see How to pass the CCMA.
These ranges are study references commonly used in medical assistant training and exam prep. They are not a substitute for your clinic's critical-call list or the current NHA CCMA Test Plan. Facility protocols and published sources can differ by a few points. On the exam, extreme out-of-range values and the correct escalation action matter more than arguing over a one-point edge case.
What lab and vital sign values should I memorize for the CCMA?
Memorize adult vitals first, then the labs that change first actions: hemoglobin, hematocrit, WBC, platelets, potassium, sodium, fasting glucose, HbA1c, INR/PT, lipids, and urinalysis basics. The NHA CCMA Test Plan expects you to recognize in-range and out-of-range vitals and laboratory values and to document and report appropriately. It does not publish one single official numeric table for every analyte.
Pro Tip: Pair every number with an action. "K+ 6.5" is not enough. "K+ 6.5: stop routine workflow, notify provider per protocol" is exam-ready.
What are normal adult vital signs for CCMA study?
| Measure | Typical adult reference | Exam flags / first action |
|---|---|---|
| Blood pressure (BP) | Normal: <120 / <80 mmHg | Elevated: 120-129 and <80. Stage 1 HTN: 130-139 or 80-89. Stage 2: �?40 or �?0. Hypertensive crisis: >180 and/or >120. Recheck technique, document, notify per protocol |
| Pulse (heart rate) | 60 to 100 bpm | <60 bradycardia; >100 tachycardia. Assess symptoms and notify if abnormal or symptomatic |
| Respirations | 12 to 20 /min | Newborn often cited as about 30 to 50 /min. Extreme adult rates or distress: escalate |
| Temperature | About 97.6 to 99.6 °F (36.5 to 37.5 °C) | Oral mean often taught as 98.6 °F (37 °C). Rectal tends higher; axillary tends lower. Fever or hypothermia: report |
| SpO2 | 95% to 100% | Values near or below 90% are commonly treated as urgent hypoxemia. Notify provider and follow oxygen/protocol orders |
| BMI | 18.5 to 24.9 kg/m² | Overweight 25 to 29.9; obesity �?0. Document accurately; counseling stays within MA scope and provider plan |
Blood pressure categories above follow American Heart Association staging language commonly taught in current MA materials (normal, elevated, Stage 1, Stage 2, crisis).
How do pediatric vital signs differ from adult ranges?
Younger patients normally have faster heart and respiratory rates and lower blood pressure. Exam stems often use an adult-looking number on a toddler (or the reverse) as a trap. Use this study card for quick comparison; pediatric charts in textbooks can vary slightly by age band.
| Age group | Heart rate (bpm) | Respirations (/min) | Systolic BP (mmHg, study range) |
|---|---|---|---|
| Newborn | About 120 to 160 | About 30 to 60 | About 60 to 90 |
| Infant (<1 year) | About 100 to 130 | About 30 to 50 | About 70 to 100 |
| Toddler (1 to 3 years) | About 90 to 120 | About 20 to 30 | About 80 to 110 |
| Adult | 60 to 100 | 12 to 20 | Normal <120 (with diastolic <80) |
Rule of thumb: the younger the patient, the faster the pulse and respirations, and the lower the expected blood pressure. Always read the age in the stem before labeling a value abnormal.

What CBC and coagulation values are highest yield?
| Test | Typical reference | Memory cue / exam action |
|---|---|---|
| Hemoglobin (Hgb) | Male 13 to 18 g/dL; Female 12 to 16 g/dL | Markedly low (for example near 7 g/dL): critical notify, do not independently treat |
| Hematocrit (Hct) | Male 42% to 52%; Female 36% to 48% | Rough rule: Hct (%) �?Hgb (g/dL) × 3 |
| RBC | Male about 4.7 to 6.1 × 10�?µL; Female about 4.2 to 5.4 × 10�?µL | Use with Hgb/Hct context; extreme lows raise anemia concern |
| WBC | About 4,500 to 11,000 /µL (4.5 to 11 × 10³) | High: infection/inflammation pattern. Very low: infection risk. Flag and report |
| Platelets | About 150,000 to 400,000 /µL | Low: bleeding risk. High: clotting risk. Follow protocol for critical lows |
| ESR | Male about 0 to 20 mm/hr; Female about 0 to 30 mm/hr | Elevated suggests inflammation; not a stand-alone diagnosis |
| PT | About 10.4 to 15.7 seconds | Used with warfarin monitoring context |
| INR | About 0.8 to 1.2 (not on therapy) | Therapeutic warfarin targets often near 2.0 to 3.0 unless ordered otherwise. Out-of-target: notify |
Practice recognition and first actions in Clinical Patient Care.
What metabolic panel values should I know cold?
| Test | Typical reference | Cut points and exam action |
|---|---|---|
| Fasting blood glucose (FBS) | About 70 to 99 mg/dL | Prediabetes often taught as 100 to 125; diabetes diagnostic threshold often �?26 (fasting). Markedly high or low with symptoms: escalate per protocol |
| HbA1c | <5.7% | Prediabetes 5.7% to 6.4%; diabetes �?.5%. Reflects roughly 2 to 3 months of glucose control |
| BUN | About 7 to 25 mg/dL | High can relate to kidney function or dehydration context |
| Creatinine | About 0.6 to 1.2 mg/dL | Key kidney function marker; rising values need provider review |
| Potassium (K+) | 3.5 to 5.0 mEq/L | Highest-alarm electrolyte for many CCMA stems. Below 3.5 or above 5.0: flag. Marked highs (for example 6.0+): immediate notify |
| Sodium (Na+) | 135 to 145 mEq/L | Outside range: flag and report; watch for fluid-balance context |
Pro Tip: If a potassium sample looks hemolyzed and the value is unexpectedly high, follow protocol for verification before assuming the patient is truly hyperkalemic. Do not invent treatment on your own.
What lipid panel targets are commonly tested?
| Test | Common study target | Cue |
|---|---|---|
| Total cholesterol | <200 mg/dL | Lower is generally better for risk teaching |
| LDL | <130 mg/dL (ideal often taught <100) | "L" = lousy cholesterol |
| HDL | >40 mg/dL (ideal often taught >60) | "H" = healthy cholesterol |
| Triglycerides | <150 mg/dL | Elevated triglycerides raise risk context |
Ladder memory: total <200 �?LDL <130 �?HDL >40.
What urinalysis findings are normal vs reportable?
| Finding | Typical expected result | Exam note |
|---|---|---|
| Specific gravity | About 1.005 to 1.030 (some materials use 1.001 to 1.035) | High: concentrated urine / dehydration pattern. Low: dilute urine / excess intake or dilution issues |
| pH | About 4.5 to 8.0 (average near 6.0) | Diet and illness can shift pH |
| Protein | Negative | Positive: report; possible kidney or other pathology context |
| Glucose | Negative | Positive: report; correlate with hyperglycemia workup |
| Ketones | Negative | Positive: report; metabolic concern |
| Nitrite / leukocyte clues | Negative (as expected) | Positive patterns often suggest UTI workup |
How should I use these numbers on CCMA exam questions?
- Read the stem for who (adult vs pediatric) and what (fasting vs random, male vs female).
- Classify the value as in-range, mildly out-of-range, or critical/extreme.
- Choose the first MA action: verify identifiers/technique when relevant, document, notify the provider, hold independent treatment advice.
- Do not diagnose or prescribe from a lab value alone.
Common miss patterns:
- Treating an extreme abnormal as "recheck next visit"
- Giving diet or OTC advice instead of notifying on a critical Hgb or K+
- Mixing therapeutic INR (often 2 to 3 on warfarin) with normal INR (about 0.8 to 1.2)
- Forgetting Hgb/Hct sex-specific ranges
- Ignoring SpO2 near 90% because the patient "looks okay" in the stem

Three speed-memory rules for exam week
- Hgb to Hct ×3: Hct (%) �?Hgb (g/dL) × 3. Example: female Hgb 12 �?Hct near 36%.
- Cholesterol ladder: <200 / <130 / >40 for total / LDL / HDL.
- Potassium alarm band: 3.5 to 5.0 mEq/L. Outside that band: flag. Extreme highs or lows with symptoms: immediate provider notification.

Frequently Asked Questions
Does NHA publish one official list of every normal lab value?
No single public numeric table covers every analyte as "the only correct range." The Test Plan requires recognition of in-range and out-of-range vitals and labs and correct reporting behavior. Use a consistent study set like this one, then follow clinic protocol on the job.
What potassium value should I treat as abnormal on the CCMA?
Treat values below 3.5 mEq/L or above 5.0 mEq/L as out of typical adult reference range. Markedly elevated results (often around 6.0 mEq/L or higher in exam stems) usually require immediate provider notification because of arrhythmia risk.
What hemoglobin is critical for an adult?
Exam stems often use values near 7 g/dL or lower as critically low relative to adult female (about 12 to 16 g/dL) or male (about 13 to 18 g/dL) ranges. The first MA action is prompt notification per protocol, not independent treatment.
Is SpO2 of 92% an emergency?
It is below the usual 95% to 100% study range and needs attention. Values approaching or below 90% are commonly framed as urgent hypoxemia in prep materials. Assess the patient, follow clinic protocol, and notify the provider.
Should I memorize pediatric vital signs too?
Yes. Use the pediatric comparison table in this guide. Adult ranges dominate many stems, but newborn and infant rates appear often. Do not apply adult bradycardia or tachypnea labels to a newborn without checking age-specific expectations.
How is INR different when a patient is on warfarin?
A person not on anticoagulation is often near 0.8 to 1.2. Therapeutic targets on warfarin are commonly near 2.0 to 3.0 unless the provider ordered a different range. Do not call a therapeutic 2.5 "normal" or "critical" without reading the therapy context in the stem.
How should I study these values without only rereading tables?
Cover the table for 10 minutes, then open practice questions and force retrieval. Log every miss with the number and the action. Re-test the same miss within 48 hours. Passive reading alone does not transfer to timed stems.
Start drilling values with actions today
- Recite adult vitals and the potassium band from memory.
- Write the Hgb/Hct ×3 examples for male and female once without looking.
- Open Clinical Patient Care and complete a short vitals/lab set.
- Take a mixed check on free CCMA practice.
- Keep the CCMA study plan calendar moving while you patch weak numbers.
Memorize the band. Practice the action. That combination is what CCMA stems reward.
