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.

Explanation
(A) The effects of morphine or an allergic response to the drug will not affect theophylline clearance. (B) Xanthines are used cautiously in clients with severe cardiac disease, liver disease, cor pulmonale, hypertension, or hyperthyroidism. Arthritis does not influence the dosage of theophylline. (C) Theophylline does not cause sedation or drowsiness. Conversely, its side effects may be exhibited by central nervous system stimulation. (D) Cimetidine decreases theophylline clearance from the system and increases theophylline levels in the blood, thus increasing the risk of toxicity.

Explanation:
(A) RhoGAM is given to Rh-negative mothers to prevent the maternal Rh immune response to fetal Rh- positive antigens. (B) If the infant is Rh positive, the mother will receive another dose postdelivery to prevent maternal sensitization. (C) Prevention of maternal sensitization will protect future pregnancies because the mother's blood will be free of antibodies against her fetus. (D) RhoGAM prevents maternal sensitization to Rh-positive blood.

Explanation
(A) A 2-year-old child is in the stage of autonomy, according to Erikson. Assembling a puzzle with large pieces enables her to "do it herself." (B) A wheelchair ride would probably be fun, but it is not directed toward helping the child to achieve autonomy. (C) Listening to a story may be fun and educational, but it is not directed toward helping the child to achieve autonomy. (D) Watching television may be a favorite activity, but it does not foster autonomy.

Explanation
(A) The nurse should emphasize what is required to elicit cooperation and help to develop a sense of autonomy. (B) The child may express discomfort verbally and should be encouraged to express his feelings.
(C) Selecting nonthreatening words to explain a procedure will prevent misinterpretation. (D) When explaining the procedure to the parent with the child present, the nurse should use words that the child can understand to avoid misunderstanding.
