A client presents at the emergency department reporting a raspy voice, cold intolerance, and fatigue. Laboratory tests indicate an elevated thyroid stimulating hormone (TSH) and low T3 and T4 levels. After the client is admitted to the telemetry unit, which intervention is most important for the nurse to implement?

A) Incorrect - Developing new screening protocols is important, but it doesn't directly indicate that the program has prevented diseases. Screening protocols might catch diseases but don't prevent them.
B) Incorrect - Clients receiving rehabilitation indicates they already had disease complications, which is not a primary prevention outcome.
C) Correct- An improvement in average client scores on risk factor knowledge tests suggests that the primary prevention program has successfully educated clients about behaviors and practices that can help prevent sexually transmitted diseases. This improvement indicates that clients have a better understanding of the risks and protective measures, which is a key indicator of program effectiveness.
D) Incorrect - Diagnosing clients early in their disease process is related to early detection (secondary prevention), not primary prevention.

Administering a large volume of medication in a single injection is not recommended for infants as it can lead to discomfort, tissue trauma, and potential complications such as muscle fibrosis or nerve injury. Dividing the medication into two injections with volumes under 1 mL is a common practice for infants and can help minimize discomfort and complications.

In addition, the nurse should select an appropriate needle size and injection site based on the infant's size and age. A 22 gauge 1 1/2 inch (3.8 cm) needle is too large for an infant and may cause discomfort and tissue damage. The nurse should use a smaller gauge needle and choose an appropriate injection site, such as the vastus lateralis muscle in the thigh or the dorsogluteal muscle in the buttocks, based on the infant's age and size.

Finally, administering an injection into the deltoid muscle is not recommended for infants as this muscle is not fully developed until later in childhood. Using a quick dart-like motion to inject into the dorsogluteal site is also not recommended as it can cause tissue damage and discomfort. Instead, the nurse should use a slow, steady technique to administer the injection while ensuring the infant is held securely by the parent or another caregiver.
