A nurse is calculating the estimated date of delivery for a patient who reports that the first day of her last menstrual period was August 10. Using Nägele’s Rule, what is the patient’s estimated date of delivery?
May 17
May 3
May 20
May 13
The Correct Answer is A
Question: Estimated date of delivery using Nägele’s Rule.
Step 1: Add 7 days to the first day of the last menstrual period. August 10 + 7 days = August 17
Step 2: Subtract 3 months from the result. August 17 - 3 months = May 17
Step 3: Add 1 year to the result. May 17 + 1 year = May 17, 2025
Answer: May 17, 2025

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.
Correct Answer is C
Explanation
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.
