A nurse is conducting a health promotion class about the use of oral contraceptives. Which of the following disorders is a contraindication for oral contraceptive use?

Rationale:

A. Drinks 3 cups of 1% milk per day: This intake is appropriate for an 8-year-old child. It supports bone development by providing sufficient calcium and vitamin D, aligning with dietary guidelines for school-age children.

B. Weight has increased by 5 kg (11 lb): A weight gain of about 2–3 kg (4.4–6.6 lb) per year is typical for children between ages 6 and 12. A 5 kg increase over one year is within normal limits and does not require provider notification unless accompanied by other concerns.

C. Height has increased by 3.8 cm (1.5 in): This is below the expected annual growth rate for an 8-year-old, which is typically 5 to 6.5 cm (2 to 2.5 in) per year. Slowed linear growth can indicate underlying medical or nutritional issues and should be reported for evaluation.

D. Consumes three meals and two snacks per day: This is a healthy and age-appropriate eating pattern for a school-age child, promoting stable energy levels and supporting growth and development.

Rationale for Correct Answers:

1. Condition: Mastitis
Mastitis is an infection of the breast tissue that commonly affects breastfeeding women. It often occurs when bacteria (usually Staphylococcus aureus) enter through a cracked or damaged nipple, allowing pathogens to travel into the milk ducts. Symptoms can start with nipple pain and breast tenderness, progressing to flu-like symptoms, localized redness, and fever if untreated.

2. Evidence: Cracked nipple
The client's report of nipple discomfort throughout feeding and visible crack noted on the left nipple are red flags for potential bacterial entry, placing her at high risk for mastitis. Cracked nipples are common in breastfeeding, especially when there is poor latch or prolonged feeding.

Rationale for Incorrect Options:

Endometritis: This is an infection of the uterine lining. However, this client is 2 weeks postpartum, denies abdominal pain, and has normal lochial progression (whitish-yellow discharge = lochia alba). Her uterus is no longer palpable, indicating appropriate involution. No signs of fever, foul-smelling discharge, or uterine tenderness are noted.

Perineal hematoma: This would present with significant perineal pain, swelling, and possibly bluish discoloration. This client reports only mild perineal discomfort (2/10), likely related to normal healing from her episiotomy.

Group B streptococcus: The client tested negative for Group B Streptococcus. Moreover, GBS is not directly related to cracked nipples or mastitis.

Large for gestational age newborn: While the newborn was indeed LGA, this mainly increases the risk for perineal trauma or shoulder dystocia, not directly mastitis.
