A nurse in a clinic is teaching the mother of a 4-month-old infant who has been breastfed. The mother plans to switch her infant to an iron-fortified formula. Which of the following should be included in the teaching?

Choice A reason:
The deltoid muscle, while commonly used for IM injections in older children and adults, is not the preferred site for newborns due to their underdeveloped muscle mass in this area. Administering an injection in the deltoid could increase the risk of injury to the surrounding nerves and tissues in newborns.

Choice B reason:
The vastus lateralis muscle is the recommended site for IM injections in newborns. It is the preferred location because it is the largest muscle in the thigh and has sufficient mass to absorb the medication effectively. This muscle is located on the anterolateral aspect of the thigh and is considered the safest site with the least risk of damaging blood vessels, nerves, or bone.

Choice C reason:
The dorsogluteal muscle, located in the buttocks, was once a common site for IM injections. However, it is no longer recommended due to the high risk of injury to the sciatic nerve and significant blood vessels in the area. Additionally, the fat content in the buttocks can affect the absorption of the medication.

Choice D reason:
The ventrogluteal muscle, also located in the hip area, is another site for IM injections but is more suitable for older children and adults. For newborns, the vastus lateralis remains the preferred site due to easier access and less risk of complications.

Choice A reason:
Elevating the client's legs can help increase venous return to the heart and may be beneficial in some cases of hypotension. However, it is not the first-line action for hypotension in a client with an epidural block during labor.

Choice B reason:
Notifying the provider is important, but it is not the immediate priority action. The provider should be informed after initial measures to stabilize the client's blood pressure have been taken.

Choice C reason:
Placing the client in a lateral position is the priority nursing action for hypotension during labor with an epidural block. This position helps improve uterine blood flow and can help increase blood pressure. It is a part of the initial management of hypotension in this situation.

Choice D reason:
Monitoring vital signs every 5 minutes is an important part of ongoing assessment but is not the immediate priority action. The nurse should first address the hypotension and then continue to monitor the client closely.
