NHA Medical Assistant (CCMA)

A medical assistant takes an adult patient's oral temperature and gets a reading of 98.8°F. How should this result be interpreted?

1. AWithin the normal adult oral range of about 97.6°F to 99.6°FĐúng
2. BBelow the normal range; recheck rectally
3. CInvalid, because oral temperature is never used on adults
4. DA low-grade fever that must be reported immediately

Vì sao: The accepted normal adult oral temperature range is roughly 97.6°F to 99.6°F, with 98.6°F as the traditional average, so 98.8°F is normal. It is neither below range nor a fever, so recheck and immediate reporting are unnecessary. Oral temperature is a standard, acceptable route for alert adults who can hold the probe under the tongue.

A medical assistant is giving an intramuscular injection in the deltoid. At what angle should the needle be inserted?

1. A90 degrees, perpendicular to the skinĐúng
2. B30 degrees with the bevel down
3. C45 degrees to the skin surface
4. D10 to 15 degrees, nearly parallel to the skin

Vì sao: Intramuscular injections are given at a 90-degree angle so the needle passes through skin and subcutaneous tissue into the muscle. A 45-degree angle is used for many subcutaneous injections, and 10 to 15 degrees with the bevel up is the intradermal angle. Injecting IM medication too shallowly can cause irritation and poor absorption.
