A nurse is preparing to administer metronidazole 2 g PO to a client who has trichomoniasis. Available is metronidazole 250 mg tablets.
How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies.
Do not use a trailing zero.) .
The Correct Answer is ["8"]
Step 1 is to determine the total amount of metronidazole needed, which is 2 g.
Step 2 is to convert grams to milligrams, as the available medication is in milligrams. So, 2 g is equal to 2000 mg.
Step 3 is to calculate the number of tablets needed. Each tablet contains 250 mg of metronidazole. Therefore, the calculation is 2000 mg ÷ 250 mg/tablet.

Correct Answer is C
Explanation
Choice A rationale
Pale, translucent skin is not typically a characteristic of a postterm newborn. Postterm newborns often have dry, peeling, loose skin.
Choice B rationale
Large deposits of subcutaneous fat are not usually seen in postterm newborns. In fact, these babies may appear abnormally thin, especially if the function of the placenta was severely reduced near the end of the pregnancy.
Choice C rationale
Nails extending over the tips of the fingers is indeed a common characteristic of postterm newborns. This is because the baby has had more time to grow in the womb.
Choice D rationale
A thin covering of fine hair on the shoulders and back is not typically seen in postterm newborns. This characteristic is more commonly associated with preterm babies.
Correct Answer is A
Explanation
Choice A rationale
Washing a baby’s face with plain water is a safe and effective way to keep it clean without causing irritation or dryness. This is especially important for newborns, whose skin is more sensitive than that of older children and adults.
Choice B rationale
Bumper pads are not recommended for use in a baby’s crib. They pose a risk of suffocation, strangulation, and entrapment. Instead, the crib should be kept bare, with only a firm mattress and a fitted sheet.
Choice C rationale
A soft mattress is not safe for a baby’s crib. It increases the risk of sudden infant death syndrome (SIDS) because it can conform to the shape of the baby’s head or face, leading to suffocation. A firm mattress is recommended.
Choice D rationale
Bathing a baby immediately after feeding is not recommended. It can cause discomfort and may lead to vomiting. It’s better to wait at least a little while after a feeding before bathing the baby.
