(A) The 9-month-old infant can sit alone for long periods. By the age of 6 months, many infants can pull themselves to a sitting position. (B, C, D) This skill represents normal development.

Explanation
(A) This condition causes aseptic necrosis of the head of the femur in the acetabulum. Drinking large quantities of milk at this time cannot hasten recovery. (B) The aim of treatment is to keep the head of the femur in the acetabulum. Non-weight-bearing is essential. Activity causes microfractures of the epiphysis. (C) In addition to non-weight-bearing, clients are often placed on bedrest, which helps to reduce inflammation.
Later, active motion is encouraged. (D) Weight is not generally an issue with this disease. Slipped femoral capital epiphysis, which is most frequently observed in obese pubescent children, usually requires a weight reduction diet.

(A)
Bradycardia is an expected assessment during the postpartum period. (B) Diuresis can occur during labor and the postpartum period and is an expected physiological adaptation.
(C)
A return of rubra after the serosa period may indicate a postpartal complication. (D) Diaphoresis, especially at night, is an expected physiological change and does not indicate an infectious process. Bradycardia, diuresis, and diaphoresis are normal postpartum physiological responses to adjust the cardiac output and blood volume to the nonpregnant state.

Explanation:
(A) Term neonates are predominantly in a flexed position with strong active muscle tone that increases.
Newborns are slightly hypertonic. (B) Neonatal movements may be jerky and uncoordinated as the neonate works against gravity in contrast to the buoyancy of the amniotic fluid. Jerky movements must be differentiated from the tremors of hypoglycemia, hypocalcemia, and neurological dysfunction. (C) Growth of the newborn progresses in a cephalocaudal, proximal-distal fashion. Knowledge regarding infant development may facilitate parental involvement and infant stimulation. (D) Asymmetrical movements of the extremities are indicative of neurological dysfunction.

Explanation:
(A) Inhalers should be cleaned once a day. They should be taken apart, washed in warm water, and dried according to manufacturer's instructions. Soaking in bleach is inappropriate. (B) A common side effect of inhaled steroid preparations is oral candidal infection. This can be prevented by drinking a glass of water or gargling after using a steroid inhaler. (C) There is nothing wrong with sitting and resting after using a steroid inhaler, but it is not necessary. (D) If a person is using a steroid inhaler as well as a bronchodilator inhaler, the bronchodilator shouldalways be used first. The reason for this is that the bronchodilator opens up the person's airways so that when the steroid inhaler is used next, there will be better distribution of medication.
