Questions 1 – 35
PROCEDURES
1. Which of the following is the normal temperature range for the oral method?
A. 97.6–99.6 degrees Fahrenheit
B. 96.6–98.6 degrees Fahrenheit
C. 93.6–97.9 degrees Fahrenheit
D. 98.6–100.6 degrees Fahrenheit
CORRECT ANSWER A — 97.6–99.6 degrees Fahrenheit
RATIONALE Normal oral temperature is 97.6–99.6°F, with 98.6°F as the average. Rectal
temperatures run approximately 1°F higher; axillary temperatures run
approximately 1°F lower. Option B is too low. Option C is hypothermic. Option D's
low end is the average normal, and the high end exceeds normal. CNAs must
know normal ranges to identify and report abnormal readings.
2. What can an overbed table be used for?
A. Placement of dirty linens
B. Placement of bedpans
C. Placement of meals
D. Placement of urinals
CORRECT ANSWER C — Placement of meals
RATIONALE The overbed table is a CLEAN surface used for meals, personal items, and
activities. It should NEVER be used for contaminated items such as dirty linens
(A), bedpans (B), or urinals (D). Cross-contamination from placing soiled items on
eating surfaces can cause infection. The overbed table should be cleaned before
and after meal service.
, 3. Which of the following thermometers is used to measure temperature from the ear?
A. Oral thermometer
B. Rectal thermometer
C. Tympanic thermometer
D. Axillary thermometer
CORRECT ANSWER C — Tympanic thermometer
RATIONALE The tympanic thermometer measures temperature via the tympanic membrane
(eardrum) in the ear canal. It uses infrared technology and provides a rapid
reading. The oral thermometer (A) is for mouth use (color-coded green or blue).
The rectal thermometer (B) is for rectal use (color-coded red). The axillary
thermometer (D) is for armpit use. Tympanic thermometers should be inserted
1/4 to 1/2 inch into the ear.
4. Which temperature site is considered to be the most accurate?
A. Oral
B. Rectal
C. Axillary
D. Tympanic
CORRECT ANSWER B — Rectal
RATIONALE Rectal temperature is the most accurate because it measures core body
temperature with minimal external influence. It is typically 1°F higher than oral.
Axillary (C) is the LEAST accurate. Oral (A) and tympanic (D) are intermediate in
accuracy. Rectal temperatures are contraindicated in certain conditions (rectal
surgery, hemorrhoids, cardiac patients due to vagal stimulation risk). The NA
must hold the thermometer at all times during rectal measurement.
