A nurse is caring for a 3-year-old toddler who has dehydration.
Which of the following findings should the nurse report to the provider?
Sodium 142 mEq/L.
Respiratory rate 22/min.
Potassium 3.9 mEq/L.
Heart rate 148/min.
The Correct Answer is D
Choice A rationale:
Sodium level of 142 mEq/L is within the normal range (135-145 mEq/L) for adults. However, normal ranges for children might vary slightly, but 142 mEq/L is not indicative of dehydration on its own.
Choice B rationale:
Respiratory rate of 22/min is within the normal range for a 3-year-old child (20-30 breaths/min) This rate alone does not provide evidence of dehydration.
Choice C rationale:
Potassium level of 3.9 mEq/L is within the normal range (3.5-5.1 mEq/L) for children. Like sodium, normal ranges for potassium may differ slightly in pediatric patients, but 3.9 mEq/L is not alarming on its own.
Choice D rationale:
Heart rate of 148/min is elevated for a 3-year-old child. Tachycardia is a common sign of dehydration in pediatric patients. This increased heart rate indicates the body's compensatory mechanism to maintain cardiac output in response to decreased blood volume, a typical consequence of dehydration.

Correct Answer is D
Explanation
Choice A rationale:
Wire cutters are not necessary equipment for postoperative care after a thoracotomy with chest tube placement. Wire cutters are used for cutting wires and may be found in orthopedic or surgical trays, but they are not specifically required for thoracotomy care.
Choice B rationale:
A tracheostomy tray is not necessary for postoperative care following a thoracotomy with chest tube placement. Tracheostomy trays contain supplies for managing a tracheostomy, which is a procedure involving the creation of an opening in the neck to help with breathing. This procedure is not related to thoracotomy care.
Choice C rationale:
Montgomery straps are not necessary equipment for postoperative care after a thoracotomy with chest tube placement. Montgomery straps are used to secure dressings or bandages without adhesive tape. They are not typically used in thoracotomy care.
Choice D rationale:
A padded clamp is essential equipment for postoperative care after a thoracotomy with chest tube placement. The clamp is used to temporarily close or occlude the chest tube during transportation or when changing the drainage system. This prevents air from entering the pleural space, maintaining proper suction and preventing complications such as pneumothorax.
Correct Answer is D
Explanation
- A. Instructing the client about the importance of regular medical appointments is important, but not the priority. The nurse should first ensure that the client knows how to manage their blood glucose levels and administer insulin at home.
- B. Encouraging the client to participate in daily exercise is beneficial, but not the priority. The nurse should first ensure that the client knows how to monitor their blood glucose levels and adjust their insulin dose accordingly.
- C. Explaining proper foot care techniques to the client is essential, but not the priority. The nurse should first ensure that the client knows how to prevent and treat hypoglycemia and hyperglycemia, which can have serious complications.
- D. Ensuring that the client understands the medication regimen is the priority. The nurse should teach the client about the types, actions, doses, and administration times of insulin, as well as how to store and dispose of it safely.
