The Correct Answer is Option D
Volume of water to add (mL) = total volume of formula on hand (mL) – total volume of formula on hand (mL)
Diluted strength
mL water = (200mL / ¾) – 200mL = (200mL x 4) / (1x3) – 200mL = 267mL – 200mL = 66.6666667 = 67mL

Answers B, C, and D are improper ways of ambulating the client who is blind; therefore, they are incorrect.
The Correct Answer is Option A
A. Private room or cohort client
B. Personal respiratory protection device
C. Private room with negative airflow pressure
D. Mask worn by staff when the client needs to leave the room
Meningitis is transmitted by droplet infection. Precautions for this disease include a private room or cohort client and the use of a standard precaution mask.

A. Test the corneal reflexes.
B. Test the 6 cardinal positions of gaze.
C. Test visual acuity, using a Snellen eye chart.
D. Test sensory function by asking the client to close the eyes and then lightly touching the forehead, cheeks, and chin.
Testing the 6 cardinal positions of gaze (diagnostic positions test) is done to assess for muscle weakness in the eyes. The client is asked to hold the head steady, and then to follow the movement of an object through the positions of gaze. The client should follow the object in a parallel manner with the 2 eyes. A Snellen eye chart assesses visual acuity and cranial nerve II (optic). Testing sensory function by having the client close his or her eyes and then lightly touching areas of the face and testing the corneal reflexes assess cranial nerve V (trigeminal).
