A nurse assesses an oral temperature for a patient as 38.5°C (10A.3°F). What term would the nurse use to report this temperature?

Blood pressure (BP) measurement is a foundational clinical assessment, but its accuracy is highly influenced by technique, cuff size, body position, and external factors.

Rationale for correct answers:

A. Cuff too small on the device: A cuff that is too small for the client’s arm can result in falsely elevated systolic pressure.

D. Patient did not remove his long-sleeved shirt: Taking BP over clothing can interfere with cuff compression and cause falsely high readings, especially thicker or tight sleeves.

E. Insufficient time between measurements: Taking repeat BP readings too soon (e.g., within 1–2 minutes) doesn’t allow time for vascular recovery and can lead to falsely high results.

Rationale for incorrect answers:

B. Arm positioned above heart level: If the arm is above heart level, BP readings tend to be falsely low, not high. To avoid error, the arm should be at heart level.

C. Slow inflation of the cuff by the machine: Slow deflation, not inflation, affects BP accuracy.

Take-home points:

• Improper cuff size, measuring over clothing, and not waiting long enough between readings can all cause falsely elevated BP.
• BP measurement should be performed with the arm at heart level, cuff directly on skin, and with the correct-sized cuff to ensure accuracy.

Vital signs provide critical information about a client's physiological status. When evaluating temperature, it's essential to consider normal ranges, the client’s baseline, and potential factors affecting the measurement (e.g., equipment error, recent food or fluid intake).

Rationale for correct answer:

B. Check what the client’s temperature was the last time it was taken: A single temperature reading may be normal or abnormal depending on the client's baseline pattern. Comparing previous readings helps determine whether this value is consistent or a new finding that might warrant further assessment.

Rationale for incorrect answers:

A. Wait 15 minutes and retake it: There is no indication that the initial temperature was affected by recent activity such as eating, drinking, or smoking, which could temporarily alter an oral temperature.

C. Retake it using a different thermometer: There’s no indication that the equipment is malfunctioning. If the reading had been inconsistent with the client’s condition, or if the thermometer showed an error, retaking with a different device would be reasonable.

D. Chart the temperature; it is normal: While 3F.1°C (97.2°F) is technically within the lower limit of normal, this option skips an important clinical validation step: checking for trends. The nurse may miss a developing pattern of hypothermia or a declining trend in temperature.

Take-home points:

• Always compare current vital signs with the client’s baseline and trends to determine clinical significance.
• Low-normal temperature readings require context- never assume they're acceptable without reviewing previous data and clinical presentation.
