Patient intake and vitals is 14 of the 150 scored items on the NHA CCMA. Answer 10 exam style questions on vital signs and measurements and see exactly which concepts would cost you points on test day.
Start the 10 questions →A medical assistant selects a blood pressure cuff for an adult with a large upper arm. Which cuff characteristic is MOST important for an accurate reading?
These questions cover blood pressure technique, blood pressure classification, orthostatic measurements, pulse and respirations. Each one shows the correct answer and why every other option is wrong, so a miss tells you exactly what to review before the CCMA.

Answer: A. Cuff sizing is based on the arm, not the patient's age: the bladder should be about 40% of the arm circumference in width and about 80% in length. A cuff that is too small reads falsely high; too large reads falsely low.
Why not B: The bladder is centered over the brachial artery, on the inner upper arm, not the ulnar artery at the wrist.
Why not C: Clothing between the cuff and skin distorts the reading; the cuff goes on a bare arm.
Why not D: One size does not fit all adults; a standard cuff on a large arm produces a falsely high reading.
Exam tactic: Cuff too small = falsely HIGH, cuff too large = falsely LOW. Size to the arm, never to the age.
Answer: A. Under the current ACC/AHA classification, systolic 120 to 129 with diastolic under 80 is 'elevated.' Normal is under 120 and under 80; stage 1 is 130 to 139 or 80 to 89; stage 2 is 140 or higher or 90 or higher.
Why not B: Stage 1 begins at systolic 130 or diastolic 80; this reading is below both.
Why not C: Stage 2 requires 140 or higher systolic or 90 or higher diastolic.
Why not D: Normal requires systolic under 120; 128 is above that threshold.
Exam tactic: Memorize the ladder: <120/<80 normal, 120-129/<80 elevated, 130-139 or 80-89 stage 1, 140+ or 90+ stage 2.
Answer: D. Orthostatic vitals are taken supine after rest, then sitting, then standing, with readings repeated after the patient has stood for about 1 to 3 minutes. A drop of about 20 mmHg systolic or 10 mmHg diastolic, or a marked pulse rise, is significant and reported.
Why not A: Walking is not part of orthostatic measurement.
Why not B: Comparing arms checks for arm-to-arm difference, not orthostatic change.
Why not C: The sequence moves from lying to standing so a drop can be detected; reversing it defeats the purpose.
Exam tactic: Orthostatic = lying → sitting → standing, and stay near the patient because that is when they faint.
Answer: C. An irregular rhythm or a medication that affects heart rate calls for the apical pulse auscultated at the fifth intercostal space, midclavicular line, counted for a full 60 seconds. Short counts multiplied up magnify any irregularity.
Why not A: The carotid site is reserved for emergencies, and 30 seconds is too short for an irregular rhythm.
Why not B: Pedal pulses assess peripheral circulation, not the heart rate for medication decisions.
Why not D: A 15-second radial count is acceptable only for a regular rhythm; it is unreliable with irregularity.
Exam tactic: Irregular or rate-changing drug → apical, one full minute, no shortcuts.
Answer: C. Normal adult resting respirations are roughly 12 to 20 per minute. A rate above that range is tachypnea. It should be reported, along with the shallow quality, because it can signal pain, anxiety, fever, or respiratory compromise.
Why not A: Bradypnea is an abnormally slow rate, below about 12 per minute.
Why not B: Apnea is absence of breathing.
Why not D: Eupnea is normal, unlabored breathing at a normal rate.
Exam tactic: Tachy = fast, brady = slow, a- = none, eu- = good/normal. The prefixes carry the answer.
Answer: A. Rectal temperature reflects core temperature and runs roughly 1°F (about 0.5°C) above oral. Axillary is a surface reading and runs roughly 1°F below oral. Documenting the site is essential so the provider interprets the number correctly.
Why not B: The sites differ predictably, which is why the site is always charted.
Why not C: Axillary is lower, not higher, than oral.
Why not D: The relationship is reversed: rectal is the highest of the three.
Exam tactic: Rectal high, oral middle, axillary low. Always chart the site with the number.
Answer: A. Standard pulse oximetry cannot distinguish oxyhemoglobin from carboxyhemoglobin. In suspected carbon monoxide exposure the SpO2 can look normal while the patient is actually hypoxic, so the reading is unreliable and the situation is treated as an emergency regardless.
Why not B: Hyperventilation is not diagnosed by SpO2, and 98% is within the normal range.
Why not C: Pulse oximeters read accurately across the normal range; the problem is what they are measuring.
Why not D: Confusion is a symptom of CO poisoning, not a cause of false readings.
Exam tactic: Carbon monoxide fools the oximeter. Symptoms plus exposure history outrank a 'normal' SpO2.
Answer: D. Head circumference is measured at well-child visits through about 36 months to monitor brain growth and detect problems such as hydrocephalus or microcephaly. The tape is placed above the eyebrows and ears around the widest part of the occiput.
Why not A: Length (recumbent) or height (standing) is measured at every age.
Why not B: Temperature is a vital sign taken as needed at any age.
Why not C: Weight is measured at every age.
Exam tactic: Head circumference belongs to the under-3 visit; after that it drops off the routine list.
Answer: D. A temperature of 100.4°F (38°C) or higher is the widely used threshold for fever. Normal body temperature varies around 98.6°F, so values just above it are not fever. Documenting the site matters because rectal readings run about 1°F higher.
Why not A: 98.6°F is the traditional average normal value, not a fever.
Why not B: 101.5°F is a fever, but it is not the threshold; fever begins at 100.4°F.
Why not C: 99.0°F is within normal daily variation.
Exam tactic: 100.4°F / 38°C is the number to memorize; everything below is normal variation.
Answer: C. Low blood pressure with a fast pulse, rapid breathing, fever, and altered alertness is a pattern that can indicate sepsis or shock and needs immediate provider evaluation. The assistant's scope is to recognize the pattern, stay with the patient, and escalate right away, not to diagnose or treat.
Why not A: Routine queuing delays care for a patient who may be deteriorating.
Why not B: An unstable patient is never left unobserved in a waiting room.
Why not D: Comfort measures and a 30-minute wait are outside scope for an unstable patient and delay escalation.
Exam tactic: Abnormal vitals plus a change in mental status = escalate now, stay with the patient.
