A nurse is reinforcing teaching with the guardian of a newborn about measures that can be taken to minimize the risk of sudden unexpected infant death (SUID). Which of the following instructions should the nurse include in the teaching?

Rationale:

A. Nystagmus: Nystagmus is characterized by involuntary eye movements and is typically associated with vestibular disorders, multiple sclerosis, or congenital conditions. It is not a symptom of macular degeneration, which primarily affects the retina.

B. Astigmatism: Astigmatism is a refractive error due to an irregularly shaped cornea or lens. It is unrelated to macular degeneration, which involves degeneration of the macula—the part of the retina responsible for sharp central vision.

C. Loss of central vision: Macular degeneration leads to progressive deterioration of the macula, resulting in blurred or complete loss of central vision while peripheral vision remains intact. This is a hallmark symptom and significantly affects activities like reading and recognizing faces.

D. Client reports sharp pain: Macular degeneration does not typically cause pain. It is a painless condition, and the presence of sharp eye pain may suggest another acute ocular issue such as glaucoma or injury, not related to macular changes.

Rationale:

A. "You should replace your diaphragm every 2 years": Diaphragms generally need to be replaced every 1 to 2 years, depending on the manufacturer’s guidelines and wear and tear. However, it is more important to be aware of refitting needs related to physiological changes.

B. "You should be refitted for your diaphragm if you have a 10 percent weight fluctuation.": Significant weight changes, usually around 10 to 15 percent, can alter pelvic anatomy and affect diaphragm fit, increasing the risk of contraceptive failure. Therefore, refitting is recommended after notable weight fluctuations.

C. "You should insert the diaphragm when your bladder is full.": The bladder should be empty when inserting the diaphragm to avoid discomfort and ensure proper placement over the cervix. A full bladder can cause displacement and increase the risk of failure.

D. "You should remove your diaphragm 4 hours after intercourse.": The diaphragm should be left in place for at least 6 hours after intercourse to ensure adequate sperm immobilization and contraceptive effectiveness. Removing it too early may increase the risk of pregnancy.
