A nurse is preparing to administer cimetidine 300 mg PO twice daily to a client. The amount available is cimetidine 300 mg/tablet. How many tablets should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["1"]

Number of tablets = Desired dose (mg) / Tablet strength (mg/tablet)

In this case:

Desired dose = 300 mg
Tablet strength = 300 mg/tablet

Plugging the values into the formula:

Number of tablets = 300 mg / 300 mg/tablet = 1 tablet

Correct Answer is A

Explanation

A. Assessing visual acuity directly tests cranial nerve II (the optic nerve), which is responsible for vision.

B. Eliciting the gag reflex tests cranial nerves IX (glossopharyngeal) and X (vagus), not cranial nerve II.

C. Checking for pupillary response to light primarily assesses the function of cranial nerve II but is more associated with cranial nerve III (oculomotor) since it involves the constriction of the pupil. While relevant, it is not the best standalone action for assessing cranial nerve II specifically.

D. Observing for facial symmetry is associated with cranial nerve VII (facial nerve), not cranial nerve II.

A. Use the bell of the stethoscope B. Palpate the chest wall to feel the intensity of the murmur C. Use a Doppler ultrasound device D. Percuss the thorax cavity

Correct Answer is A

Explanation

A. The bell of the stethoscope is best used to listen for low-pitched sounds, including some types of murmurs, and can help assess the quality and intensity of a cardiac murmur.

B. While palpation can provide some information about the heart's function (such as thrills), it is not the primary method for assessing the quality of a murmur.

C. A Doppler ultrasound device is used for measuring blood flow and can help in assessing murmurs but does not provide the quality assessment needed for characterizing a murmur.

D. Percussion is not typically used to evaluate murmurs; it is more useful for assessing the size and borders of organs.
