A client with persistent low back pain has received a prescription for an electronic stimulator (TENS) unit. After the nurse applies the electrodes and turns on the power, the client reports feeling a tingling sensation. How should the nurse respond?

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.

Assessing the client's level of consciousness involves observing their responsiveness, orientation, and ability to follow commands. If the client is unresponsive or exhibits any signs of altered consciousness, the nurse should immediately activate the emergency response system and begin resuscitative measures, such as administering oxygen and initiating cardiopulmonary resuscitation (CPR) if necessary.

Once the client's level of consciousness is established and the emergency response system has been activated if necessary, the nurse can proceed to assess the depth of the slashes, estimate the amount of blood loss, and find the object used to cause the injuries. These assessments will provide important information about the extent and severity of the client's injuries, which will guide subsequent interventions.
