A client asks the nurse about a prescription for the antihistamine, diphenhydramine (Benadryl). The nurse should teach the client that this medication is contraindicated in clients who have a history of which condition?

Choice A Reason:

Use good body mechanics is correct. Good body mechanics involve using the body in an efficient and careful way to prevent injury. This includes bending at the knees instead of the waist, keeping the back straight, and using the legs to lift heavy objects. Proper body mechanics reduce the strain on the back and joints, preventing injuries.

Choice B Reason:

Maintain proper posture is also important but is part of using good body mechanics. Proper posture involves keeping the spine in a neutral position, avoiding slouching, and ensuring that the head is aligned with the spine. This helps distribute weight evenly and reduces the risk of injury.

Choice C Reason:

Use assistive devices is correct. Assistive devices such as transfer boards, mechanical lifts, and gait belts can help reduce the physical strain on nurses when moving or lifting patients. These devices are designed to make tasks safer and easier, thereby minimizing the risk of back and joint injuries.

Choice D Reason:

Stay physically fit is also important. Physical fitness helps maintain muscle strength, flexibility, and endurance, which are crucial for performing physically demanding tasks. Regular exercise can help prevent injuries by improving overall body mechanics and reducing fatigue.

Choice A Reason:

The gastrocnemius muscle, located in the calf, is not a recommended site for intramuscular injections in newborns. This muscle is not typically used due to its small size and the difficulty in accessing it safely for an injection.

Choice B Reason:

The dorsogluteal muscle, located in the buttocks, is also not recommended for newborns. This site is avoided because of the risk of damaging the sciatic nerve and the relatively thick layer of subcutaneous fat, which can interfere with the absorption of the medication.

Choice C Reason:

The vastus lateralis muscle, located in the thigh, is the preferred site for intramuscular injections in newborns. This muscle is well-developed at birth and provides a large, easily accessible area for injections. It is also away from major blood vessels and nerves, making it a safe and effective site for administering medications like vitamin K.

Choice D Reason:

The ventrogluteal muscle, located on the side of the hip, is another site used for intramuscular injections, but it is not typically recommended for newborns. This site is more commonly used in older children and adults due to its deeper location and the need for precise anatomical knowledge to avoid complications.
