A nurse is providing teaching about home care to the parent of a child who has scabies.
Which of the following instructions should the nurse include in the teaching?

The correct answer is d. Exhibits head lag when pulled to a sitting position.

Choice A: Unable to hold a bottle At around 6 months of age, some babies can hold their own bottle. This is not a concerning finding for a 5-month-old infant. Therefore, this is not the correct answer.

Choice B: Unable to roll from back to abdomen Rolling over often starts around 4-6 months, so it’s not unusual for a 5-month-old to still be developing this skill. Therefore, this is not the correct answer.

Choice C: Absent grasp reflex The grasp reflex is an involuntary movement that your baby starts making in utero and continues doing until around 6 months of age. The grasp reflex lasts until the baby is about 5 to 6 months old. Therefore, this is not the correct answer.

Choice D: Exhibits head lag when pulled to a sitting position By the age of 5 months, most infants have developed enough strength in their neck and upper body to control their head movement. This means they should not exhibit a significant head lag when pulled to a sitting position1. If this is not the case, it could indicate a delay in motor development or a potential neurological issue, which should be reported to the healthcare provider for further evaluation. Therefore, this is the correct answer.

A potassium level of.2 mEq/L is considered low.

Low potassium levels can cause muscle weakness and spasms.

Hyporeflexia refers to below normal or absent reflexes and can be a sign of muscle weakness.

Choice A is wrong because oliguria, or decreased urine output, is not a common symptom of low potassium levels.

Choice B is wrong because hypertension, or high blood pressure, is not a common symptom of low potassium levels.

Choice D is wrong because hyperactive bowel sounds are not a common symptom of low potassium levels.
