A nurse is reinforcing teaching with an adolescent about self-administration of insulin. Which of the following instructions should the nurse include?

A. Administer magnesium sulfate IM to the child: Seizures are typically managed with anticonvulsant medications or other specific treatments, but magnesium sulfate is primarily used in other conditions, such as preeclampsia in pregnant women.
B. Place a folded blanket under the child's head: Placing a folded blanket or soft material under the child's head is a safe action to prevent injury during a tonic-clonic seizure. It helps protect the head from hitting the floor or any hard surfaces during the seizure.
C. Prevent movement of the child's extremities: It is not recommended to try to prevent movement of the child's extremities during a tonic-clonic seizure. Trying to restrain or hold the child down can cause injury. The goal is to ensure the child’s safety and prevent injury.
D. Put a tongue blade between the child's teeth: Inserting a tongue blade between the child’s teeth is dangerous and should never be done. It could lead to injury, including broken teeth or damage to the child's mouth or throat.

Rationale for Correct Choices:

• Dextrose 5% in sodium chloride with 20 mEq potassium chloride/L at 75 mL/hr: The prescription for dextrose 5% with potassium chloride at 20 mEq/L should be clarified because the child's potassium level is elevated at 6.2 mEq/L (normal range is 3.4 to 4.7 mEq/L). Administering additional potassium could worsen hyperkalemia, which could lead to dangerous complications like arrhythmias.
• Laboratory values: The child's potassium level is already high, and adding more potassium via IV fluids could increase the risk of severe hyperkalemia. The nurse should clarify this prescription to avoid potential harm.

Rationale for Incorrect Choices:

• Piperacillin and tazobactam 4g IV every 8 hr: This antibiotic is appropriate for treating pneumonia in a child with cystic fibrosis. No issues with laboratory values or contraindications are present in this case, so clarification is unnecessary.
• Dornase alfa 2.5 mg inhalation every day: Dornase alfa is used to break down mucus in the lungs of children with cystic fibrosis, and it is prescribed appropriately for this patient. The child’s current condition and medications do not warrant clarification for this prescription.
• Pancrelipase 8,000 units with meals: Pancrelipase is indicated for the child’s cystic fibrosis to assist with digestion, and the prescribed dosage seems appropriate for the child’s weight and condition.
• Albuterol nebulizer 2.5 mg inhalation every 4 hr: Albuterol is used for airway clearance, which is appropriate for managing the child's respiratory symptoms. No clarification is needed for this prescription based on the current findings.
• Vital signs: While the child's heart rate and temperature are elevated, they are within expected ranges for the child’s condition (fever, pneumonia, and cystic fibrosis). There is no immediate need for clarification of medications based on vital signs alone.
• Scheduled therapapy: The child is scheduled for chest physiotherapy and airway clearance therapy, which are standard treatments for cystic fibrosis and pneumonia. There is no issue with the scheduled therapies that requires clarification of the medications.
• Diet: The child has been prescribed a high-protein, high-fat diet to support nutritional needs, especially important in cystic fibrosis. The diet does not require any clarification in relation to the prescribed medications.
• Pre-existing conditions: The child’s pre-existing condition of cystic fibrosis is already taken into account in the prescribed treatments, and no adjustment is needed based on the conditions present.
