A nurse is preparing to administer ceftriaxone 300 mg IM into the right vastus lateralis. Which of the following actions should the nurse take to locate the site of injection?

A. Place the heel of the hand on the greater trochanter and the index finger on the anterior superior iliac crest: This method is used to locate the ventrogluteal site, not the vastus lateralis.

B. Measure two fingerbreadths below the acromion process: This technique is used to identify the deltoid muscle for IM injections. It is not appropriate when the vastus lateralis is the intended site for medication administration.

C. Ensure to find a place 2 inches away from the umbilicus and free of bruising: This description refers to a subcutaneous injection in the abdomen, commonly used for medications like insulin or heparin, not for IM injections.

D. Measure a handbreadth above the knee and a handbreadth below the greater trochanter: This is the correct technique for locating the vastus lateralis muscle. It ensures the injection is given in the thickest part of the muscle, minimizing the risk of nerve or blood vessel injury.

A. Isolating herself from the patient: Isolation of the nurse is unnecessary and not an effective way to prevent the spread of infection. Nurses are trained to provide care while using proper infection control practices, such as hand hygiene and protective equipment.

B. Washing her hands: Hand hygiene is the most effective method to prevent the spread of infections. Proper hand washing before and after patient contact reduces the risk of transmitting pathogens, including those associated with the flu and other infections.

C. Asking for a new assignment: Requesting a new assignment does not address the prevention of infection spread. Nurses are trained to follow safety protocols, including using personal protective equipment (PPE) and practicing good hygiene to protect both patients and themselves.

D. Wearing a mask: While wearing a mask can help prevent the transmission of respiratory droplets, it is not sufficient on its own. Hand hygiene remains the most important and effective strategy for preventing the spread of infections.
