Which is the most appropriate nursing intervention for the newborn who is jittery and twitching and has a high-pitched cry?
Correct Answer: C
Rationale: The most appropriate nursing intervention for the jittery and twitching newborn with a high-pitched cry is to obtain serum glucose and serum calcium levels (Option C). These symptoms are indicative of possible hypoglycemia or hypocalcemia, which are common issues for newborns. Monitoring glucose and calcium levels will help identify and address any imbalances that may be causing these symptoms. Administering glucose (Option D) may be necessary if hypoglycemia is confirmed, but it should be based on the results of blood tests. Monitoring blood pressure (Option A) and obtaining a urine sample to detect glycosuria (Option B) are not the priority interventions in this scenario compared to assessing serum glucose and calcium levels.
