An infant weighed 7 pounds 8 ounces at birth. If growth occurs at a normal rate, what would be the expected weight at 6 months of age?

Correct Answer: A

Rationale: Infants typically double their birth weight by 6 months of age as part of normal growth and development. This doubling of weight is a common milestone used by healthcare providers to assess a baby's growth progress. Tripling the birth weight or adding 2 pounds each month would result in excessive weight gain, which is not typical or healthy for an infant. Similarly, gaining 6 ounces each week would also lead to rapid and abnormal weight gain, making it an incorrect choice.

Correct Answer: C

Rationale: In the immediate post-operative period following spinal fusion for scoliosis in a 13-year-old, it is important to maintain the patient in a flat position and perform logrolling as needed. This helps prevent injury to the surgical site and ensures proper spinal alignment. Raising the head of the bed at least 30 degrees is contraindicated as it can put strain on the surgical site. Encouraging ambulation within 24 hours may be appropriate in the recovery process but not in the immediate post-operative period. Encouraging leg contraction and relaxation after 48 hours may also be part of the rehabilitation process but is not a priority in the immediate post-operative period.

Correct Answer: C

Rationale: In the scenario of persistent vomiting, the child is at risk of developing metabolic alkalosis due to the loss of hydrochloric acid. Vomiting leads to the loss of gastric acid, resulting in an imbalance that causes metabolic alkalosis. Metabolic acidosis is incorrect as it would occur in a child with diarrhea due to the loss of bicarbonate. While diarrhea can sometimes be associated with vomiting, in this case, the primary focus is on the effects of vomiting. Hyperactive bowel sounds are not typically associated with vomiting, making this choice less relevant to the situation described.

Correct Answer: A

Rationale: It is essential for the nurse to guide the client on the initial steps in involving her 2 and 12-year-old sons in the care of their newborn sister. The most appropriate response is to 'Focus on your sons' needs during the first days at home.' In an expanded family, parents should prioritize reassuring older children that they are loved and as important as the newborn. This response acknowledges the importance of ensuring the well-being and emotional adjustment of the older siblings during the transition period. Choices B, C, and D are less appropriate as they do not directly address the emotional needs and adjustment of the older children during this significant family change.

Correct Answer: A

Rationale: The priority intervention for a patient with osteomyelitis related to a heel ulcer, with a wound that saturates the dressing every hour, is to place the patient under contact precautions. Contact precautions are essential when managing infectious wounds to prevent the spread of infection to healthcare workers, other patients, and visitors. Strict aseptic technique (Choice B) should always be used with wound care but is secondary to implementing contact precautions in this scenario. Placing another dressing (Choice C) or elevating the patient's leg (Choice D) may be necessary but do not address the immediate need for infection control measures.
