A nurse is about to administer an injection to a client when the client states, "I don't want that injection. The last time I got that I was sore for a week." The nurse goes ahead and administers the injection against the client's wishes. The nurse committed which of the following?

A. Warm the infant's extremity for 1 min prior to placing the sensor probe: While cold extremities can affect pulse oximetry readings, brief warming alone may not reliably improve accuracy. Proper probe placement and minimizing movement are more critical to obtaining consistent readings.

B. Keep the infant's foot immobilized while the sensor is in place: Immobilizing the extremity prevents motion artifact, which can interfere with pulse oximetry accuracy. This is a recommended action for continuous monitoring in infants, as movement can cause false low or fluctuating readings.

C. Place a sensor on the infant's index finger: In infants, the fingers are often too small for standard pulse oximetry probes. Preferred sites include the foot or wrist, which accommodate the sensor without compromising accuracy.

D. Place a sock over the infant's foot to secure the sensor: Covering the sensor with a sock may create pressure or interfere with proper probe function, and it can trap moisture, which affects readings. Securing the probe with gentle adhesive or specialized wraps is safer.

A. Herpes simplex virus 2: HSV-2 is a common sexually transmitted infection, but it is not universally reportable to the CDC in all states. While some jurisdictions may require reporting, it is not consistently a nationally notifiable infection.

B. Candida albicans: Candida infections are common opportunistic infections and are not considered reportable to the CDC because they occur frequently and do not typically pose a public health threat. Routine cases are managed at the clinical level.

C. Staphylococcus aureus: Although S. aureus infections, including MRSA, are clinically significant, they are generally not reportable to the CDC unless part of a specific outbreak or public health investigation. Routine cases are not mandatory to report.

D. Lyme disease: Lyme disease is a nationally notifiable infection that must be reported to the CDC. Reporting is essential for surveillance, tracking trends, and implementing public health interventions to reduce disease transmission and prevent outbreaks.
