The nurse in the trauma unit has received a report on a client who has multiple injuries following a motor vehicle crash. Which of the following actions should the nurse plan to take first?

Choice A rationale:

Placing the client in a modified Trendelenburg position is not the first intervention for a client with a deep laceration and heavy bleeding. This position involves tilting the patient with the head lower than the feet and is typically used to improve venous return in certain situations, such as hypovolemic shock. However, for a bleeding wound, the priority is to control the bleeding itself.

Choice B rationale:

Applying a tourniquet just above the wound is a drastic measure and is generally not the first intervention for controlling bleeding. Tourniquets are used when direct pressure and other methods are unsuccessful, as they can lead to complications such as tissue damage and ischemia if not used correctly.

Choice C rationale:

Starting two large-bore IV catheters is important for fluid resuscitation in cases of significant bleeding. However, it is not the first intervention. Directly controlling the bleeding takes precedence to prevent further blood loss.

Choice D rationale:

Applying pressure directly to the wound is the correct answer. This is the initial and immediate action to take when dealing with a heavily bleeding wound. Applying pressure helps to stem the bleeding by promoting clot formation and reducing blood loss. It is a vital step in managing the client's condition and preventing further deterioration.

Choice A rationale:

Applying the pulse oximeter probe to the toe is not the most appropriate location. While toe measurements can be used, the fingers are more commonly used due to their accessibility and accuracy. Edema in the hands could affect the accuracy of readings.

Choice B rationale:

The nurse should apply the pulse oximeter probe to the earlobe. This choice is correct because the earlobe is a well-vascularized and easily accessible area that provides accurate oxygen saturation measurements. Thickened toenails and edema of the hands might compromise readings in those locations.

Choice C rationale:

Applying the pulse oximeter probe to a skin fold is not a recommended site for oxygen saturation measurement. While there are various sites where pulse oximeters can be applied, the earlobe and finger are more suitable due to their consistent blood flow and accessibility.

Choice D rationale:

While applying the pulse oximeter probe to the finger is a common and acceptable practice, in this scenario, edema of the hands could affect the accuracy of the readings. The earlobe is a better choice as it is less likely to be affected by edema and can provide accurate readings.
