  1. A pulse rate greater than 100 beats per minute in an adult is called:

    Answer: Tachycardia

    Tachycardia is defined as a heart rate exceeding 100 beats per minute and must be reported to the nurse promptly.

  2. A respiratory rate below 12 breaths per minute is called:

    Answer: Bradypnea

    Bradypnea is an abnormally slow respiratory rate below 12 breaths per minute, which can indicate neurological or metabolic problems.

  3. A blood pressure reading of 140/90 mmHg or higher is classified as:

    Answer: Stage 2 Hypertension

    According to current guidelines, a blood pressure of 140/90 mmHg or higher meets the criteria for Stage 2 Hypertension and requires prompt reporting.

  4. When assessing a patient's respiratory rate, how long should the CNA count breaths?

    Answer: 30 seconds, then multiply by 2

    Counting respirations for 30 seconds and multiplying by 2 is the standard technique; a full 60 seconds is used if the rate is irregular.

  5. The apical pulse is best assessed at which location on the chest?

    Answer: Fifth intercostal space, left midclavicular line

    The apical pulse is heard at the apex of the heart, located at the fifth intercostal space along the left midclavicular line.

  6. A normal pulse oximetry (SpO2) reading for a healthy adult is:

    Answer: 95% to 100%

    A normal SpO2 reading is 95% to 100%; readings below 90% indicate hypoxia and must be reported immediately.

  7. A temperature of 100.4°F (38°C) or higher is classified as:

    Answer: Fever (pyrexia)

    A body temperature at or above 100.4°F (38°C) is defined as fever (pyrexia) and signals that the body is responding to infection or illness.
