Final answer:
When planning the discharge for a postpartum client, a nurse should inform the client that irregular bleeding is a common side effect of the subdermal implant she plans to get for contraception, while fatigue, shoulder pain, and recurrent UTIs are not typical adverse effects.
Step-by-step explanation:
A nurse who is planning the discharge for a postpartum client should inform the client that having a subdermal implant placed for contraception can have certain adverse effects. The most common side effect of hormonal implants like the subdermal implant is A) Irregular bleeding. Other possible side effects can include headaches, breast pain, nausea, and weight gain; however, B) Fatigue, C) Shoulder pain, and D) Recurrent urinary tract infections (UTIs) are not typically associated with subdermal contraceptive implants. Subdermal implants release a progestin hormone, which primarily works by preventing ovulation and thickening cervical mucus to prevent sperm from reaching an egg. As with all medical treatments, it is important for the client to discuss potential side effects and concerns with their healthcare provider.
