A 6-week-old infant with pyloric stenosis is scheduled for a pyloromyotomy. Which pre-operative nursing action has the highest priority?
A.
Mark an outline of the “olive-shaped” mass in the right epigastric area.
B.
Instruct parents regarding care of the incisional area.
C.
Monitor amount of intake and infant’s response to feedings.
D.
Initiate a continuous infusion of IV fluids per prescription.
The Correct answer and Explanation is:
The correct answer is D. Initiate a continuous infusion of IV fluids per prescription.
Explanation:
Pyloric stenosis is a condition in which the pylorus (the opening from the stomach to the small intestine) becomes hypertrophied, leading to gastric outlet obstruction. This results in vomiting, dehydration, and electrolyte imbalances in infants. By the time a 6-week-old infant is scheduled for a pyloromyotomy, the infant may already be experiencing significant fluid loss and electrolyte imbalances due to ongoing vomiting. Therefore, the highest priority pre-operative nursing action is to initiate a continuous infusion of IV fluids.
Rationale for Option D:
- Dehydration and Electrolyte Imbalance: Infants with pyloric stenosis often present with signs of dehydration, such as dry mucous membranes, decreased urine output, and signs of lethargy. Administering IV fluids helps to restore hydration and correct electrolyte disturbances, which is crucial before undergoing anesthesia and surgery.
- Surgical Considerations: Maintaining hemodynamic stability is essential before surgery. Anesthesia can exacerbate existing imbalances, making it critical to ensure that the infant is adequately hydrated.
- Prevention of Postoperative Complications: Proper fluid management can reduce the risk of complications during and after surgery, including postoperative nausea and vomiting, which can further complicate recovery.
Rationale for Other Options:
- A. Marking the olive-shaped mass is helpful for surgical identification, but it does not address the immediate need for hydration and stabilization.
- B. Instructing parents about incisional care is important postoperatively but is not a priority before surgery.
- C. Monitoring intake and response to feedings is relevant, but if the infant is unable to tolerate oral feeds due to pyloric stenosis, IV fluid therapy takes precedence to ensure hydration.
In conclusion, initiating a continuous IV fluid infusion is critical for addressing the immediate physiological needs of the infant, preparing them safely for surgery.
