A nurse is preparing to administer metronidazole 2g orally to a client diagnosed with trichomoniasis. The available medication 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.)
6 tablets
7 tablets
8 tablets
9 tablets .
The Correct Answer is C
Step 1 is to calculate the number of tablets to administer. The prescription is for 2g of metronidazole and each tablet contains 250mg. To convert grams to milligrams, we multiply by 1000, so 2g is 2000mg. We then divide the total milligrams needed by the milligrams per tablet: (2000mg ÷ 250mg/tablet) = 8 tablets.

Correct Answer is A
Explanation
Choice A rationale
Facial petechiae are small, pinpoint, red or purple spots on the skin that can occur when a newborn has a nuchal cord, or the umbilical cord wrapped around the neck. This is due to the pressure exerted on the baby’s face and neck during delivery.
Choice B rationale
Erythema toxicum is a common rash seen in newborns, characterized by tiny bumps surrounded by red skin. However, it is not specifically associated with a nuchal cord.
Choice C rationale
Periauricular papillomas are small skin tags or pits seen near the ear. They are a common minor anomaly seen in newborns, but they are not associated with a nuchal cord.
Choice D rationale
Telangiectatic nevi, also known as “stork bites,” are common birthmarks seen in newborns, characterized by small, light pink patches, usually on the back of the neck. However, they are not associated with a nuchal cord.
Correct Answer is C
Explanation
Choice A rationale
Bronchopulmonary dysplasia is a chronic lung disease that affects newborns and infants, but it is not a complication of forceps-assisted birth. It’s more common in premature babies who have been treated with oxygen and positive-pressure ventilation.
Choice B rationale
Polycythemia, a condition characterized by an increased number of red blood cells, is not a complication of forceps-assisted birth. It can occur due to various reasons, including high altitude and certain genetic disorders.
Choice C rationale
Facial palsy can occur as a complication of forceps-assisted birth. The pressure exerted by the forceps can cause damage to the facial nerve, leading to temporary or permanent facial weakness or paralysis.
Choice D rationale
Hypoglycemia, or low blood sugar, is not a complication of forceps-assisted birth. It’s more commonly seen in babies of mothers with diabetes, premature babies, and babies who are small for their gestational age.
