When completing a neurological assessment, which cranial nerves are tested within the mouth?

A.

III, IV, VIII

B.

III, II, VI

C.

IX, X, XII

D.

I, I, III

Answer and Explanation

The Correct Answer is C

A. Cranial nerves III, IV, and VIII are not involved in mouth functions; they primarily deal with eye movements and hearing.


B. Cranial nerves III, II, and VI are involved in vision and eye movement but not in mouth functions.


C. Cranial nerves IX (glossopharyngeal), X (vagus), and XII (hypoglossal) are all tested through functions such as swallowing, speech, and movement of the tongue, which occur in the mouth.


D. Option D incorrectly lists cranial nerve I twice; cranial nerve I (olfactory) is related to the sense of smell, not the mouth.

Correct Answer is C

Explanation

A. A BMI of 26 is not classified as obese; obesity typically starts at a BMI of 30.

B. Underweight is defined as a BMI less than 18.5, which does not apply to this client.

C. A BMI of 26 falls within the overweight category, which is defined as a BMI between 25 and 29.9.

D. A healthy weight is classified as a BMI between 18.5 and 24.9, which does not include a BMI of 26.

Correct Answer is C

Explanation

A. This would show a regular rhythm with a consistent rate (60-100 bpm) and clear P waves before each QRS complex, which is not present in asystole.

B. This indicates a slow heart rate (below 60 bpm) but would still display P waves and QRS complexes; asystole shows no electrical activity.

C. This is the correct interpretation as it represents a flatline on the ECG, indicating no electrical activity in the heart.

D. This would show a rapid heart rate (above 100 bpm) with present P waves, which is not the case in asystole.
