Patient Intake Vitals practice test: free NHA Certified Clinical Medical Assistant (CCMA) questions

Sample Practice Questions for Patient Intake Vitals

1. Question 1Ref: NHA CCMA Test Plan 2022 — Section 3A: Patient Intake and Vitals

   A medical assistant is taking a patient's blood pressure. The patient's arm is positioned at heart level. Which step should the assistant perform next?

   APlace the stethoscope bell over the antecubital fossaBInflate the cuff to 20 mmHg above the palpated systolic pressureCRecord the diastolic pressure at the disappearance of soundsDDeflate the cuff at a rate of 10 mmHg per second
   Show Answer & Explanation

   Correct Answer
   B. Inflate the cuff to 20 mmHg above the palpated systolic pressure

   After positioning the arm at heart level, the medical assistant should palpate for the radial pulse and inflate the cuff to approximately 20 mmHg above the point where the pulse disappears. This ensures accurate systolic measurement. Deflating too quickly can cause missed readings, and the diastolic is recorded at the muffling of sounds (Korotkoff phase 4), not total disappearance.

2. Question 2Ref: NHA CCMA Test Plan 2022 — Section 3A: Patient Intake and Vitals

   A patient presents with a fever of 102.4°F. What is the equivalent temperature in Celsius?

   A38.6°CB40.2°CC39.1°CD39.7°C
   Show Answer & Explanation

   Correct Answer
   C. 39.1°C

   To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit value and multiply by 5/9. For 102.4°F: (102.4 - 32) × 5/9 = 70.4 × 5/9 = 39.1°C. This conversion is essential for accurate vital sign documentation and comparison with established normal ranges.

3. Question 3Ref: NHA CCMA Test Plan 2022 — Section 3A: Patient Intake and Vitals

   When measuring a patient's body mass index (BMI), which formula is used?

   AWeight in grams divided by height in centimetersBHeight in centimeters divided by weight in kilogramsCWeight in kilograms divided by height in meters squaredDWeight in pounds divided by height in inches squared
   Show Answer & Explanation

   Correct Answer
   C. Weight in kilograms divided by height in meters squared

   BMI is calculated by dividing weight in kilograms by height in meters squared (kg/m²). This standardized formula allows healthcare providers to assess whether a patient is underweight, normal weight, overweight, or obese. The imperial formula (weight in pounds × 703 divided by height in inches squared) is an alternative but less commonly used in clinical settings.

4. Question 4Ref: NHA CCMA Test Plan 2022 — Section 3A: Patient Intake and Vitals

   A patient's pulse oximetry reading shows 94%. What is the normal range for oxygen saturation?

   A90% to 95%B95% to 100%C85% to 90%D80% to 85%
   Show Answer & Explanation

   Correct Answer
   B. 95% to 100%

   Normal oxygen saturation (SpO2) ranges from 95% to 100% for healthy individuals. A reading of 94% indicates mild hypoxemia and should be reported to the provider. Readings below 90% are considered significantly low and may require supplemental oxygen. Pulse oximetry is a non-invasive method of monitoring oxygen saturation and is part of routine vital sign assessment.
