A nurse in a pediatric clinic is assessing a 6-month-old infant. Which of the following findings should the nurse identify as an indication of a visual Impairment?

A. "Hemodialysis uses an electrolyte solution to clean your child's blood." Hemodialysis does not use an electrolyte solution to clean the blood. Instead, it uses a dialysate, a special fluid that helps remove waste products and excess substances from the blood through a semi-permeable membrane in the dialyzer.

B. "Hemodialysis uses an artificial membrane outside the body to clean your child's blood." This statement is accurate. Hemodialysis involves passing the child's blood through an artificial membrane (dialyzer) outside the body to filter and clean it, removing waste products and excess fluids.

C. "Hemodialysis uses your child's abdominal cavity as a membrane to clean their blood." This statement describes peritoneal dialysis, not hemodialysis. In peritoneal dialysis, the peritoneal cavity inside the abdomen is used as a natural membrane for dialysis.

D. "Hemodialysis slowly filtrates your child's blood continuously." Continuous slow filtration of blood describes Continuous Renal Replacement Therapy (CRRT), not standard hemodialysis. Hemodialysis is typically performed several times a week for a few hours each session.

A. Unable to roll from back to abdomen. Incorrect. Many infants do not roll over until closer to 6 months old, so this is not a concerning finding at 5 months.

B. Absent grasp reflex. Incorrect. The grasp reflex typically disappears around 4 to 6 months of age, so its absence is normal at this stage.

C. Unable to hold a bottle. Incorrect. Holding a bottle can vary widely, and many 5-month-olds do not yet have this skill.

D. Exhibits head lag when pulled to a sitting position. Correct. By 5 months, most infants should have sufficient neck muscle control to not exhibit head lag. Persistent head lag could indicate a developmental delay or neurological problem.
