Ordered: Digoxin (Lanoxin) 0.25 mg

Available: Digoxin (Lanoxin) 0.125 mg per tablet

Administer: _____tab(s)
Answer and Explanation

The Correct Answer is ["2"]

To administer the ordered dose of digoxin, you need to calculate how many tablets of the available strength are equivalent to 0.25 mg. You can use the formula:

Ordered dose / Available dose = Number of tablets

Plugging in the values, you get:

0.25 mg / 0.125 mg = 2 tablets

Therefore, you need to administer two tablets of digoxin 0.125 mg to give the ordered dose of 0.25 mg.

Correct Answer is C

Explanation

A. Dorsal surface of the foot:

The skin on the dorsal surface of the foot may have more pigmentation, making it potentially more challenging to detect cyanosis in individuals with dark skin.

B. Pinnae of the ears:

The ears may have variable pigmentation, and the presence of hair can affect the visibility of cyanosis. The skin on the pinnae may not be as thin as the skin on the dorsal surface of the hand.

C. Dorsal surface of the hand

When assessing for cyanosis in a client with dark skin, the nurse should examine areas with less pigmentation or areas where the skin is thin. The dorsal surface of the hand is often a suitable site, as it is less pigmented and can show bluish discoloration if cyanosis is present.

D. Conjunctivae:

The conjunctivae (the mucous membranes lining the inner surface of the eyelids and covering the white part of the eyes) are not a reliable site for assessing cyanosis in individuals with dark skin. Mucous membranes may not show cyanosis as prominently as the skin.

Correct Answer is ["0.7"]

Explanation

To calculate the amount of hydroxyzine (Vistaril) to administer, use the formula:

D (desired dose) / H (have dose) x Q (quantity) = X (amount to give)

In this case, D = 35 mg, H = 50 mg/mL, and Q = 1 mL. Plug in the values and solve for X:

35 mg / 50 mg/mL x 1 mL = 0.7 mL

Therefore, the amount of hydroxyzine (Vistaril) to administer is 0.7 mL.
