NHA Practice Test

NHA Practice Test

1. Normal Temperature Range:

- 97.6°F to 99.6°F (36.4°C to 37.6°C).



2. Fever in Pediatric Patients:

- Rectal temperature of 100.4°F (38°C) or above.



3. Normal Blood Pressure:

- Systolic less than 120 mmHg and diastolic less than 80 mmHg (120/80).



4. Resting Pulse Rate:

- Typical range: 60 to 100 bpm.



5. Respiration Rate:

- Normal range: 12 to 20 respirations per minute.



6. Vital Signs Include:

- Blood pressure, temperature, pulse, and respirations.



### Blood Pressure Measurement



1. Releasing the Dial:

- Approximately 22 mm/s.



2. Systolic Reading:

- Noted when the first heartbeat is heard.

, 3. Diastolic Reading:

- Noted when sounds stop.



4. If Unsure of Blood Pressure Reading:

- Wait one to two minutes and repeat.



5. Irregular Rhythm:

- Measure pulse for a full minute.



### Temperature Measurement Techniques



1. Rectal Temperature Position:

- Patient in Sims position.



2. Conversions:

- Celsius to Fahrenheit: \(T(C) \times \frac{9}{5} + 32 = T(F)\)

- Fahrenheit to Celsius: \((T(F) - 32) \times \frac{5}{9} = T(C)\)

- Centimeters to Inches: Multiply by 0.39.

- Pounds to Kilograms: Multiply by 0.45.

- Inches to Centimeters: Multiply by 2.54.

- Feet and Inches to Centimeters: Convert to inches and multiply by 2.54.



### Injection Techniques



1. Intramuscular Injection:

- Insert at a 90° angle.



2. Intradermal Injection:

- Insert at a 15° angle.
