A nurse is admitting a client who has a wound infected with methicillin-resistant Staphylococcus aureus (MRSA). Which of the following types of precautions should the nurse plan to initiate?

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.

The correct answer is choice B. Increased anteroposterior diameter of the chest.

Choice A rationale:

Petechiae on the chest (Choice A) are tiny red or purple spots that appear on the skin due to small blood vessel breakage. They are not typically associated with COPD and emphysema. Petechiae are more often related to conditions like thrombocytopenia or certain infections, where blood clotting is impaired.

Choice B rationale:

Increased anteroposterior diameter of the chest, often referred to as "barrel chest," is a characteristic finding in clients with COPD and emphysema. This occurs due to the hyperinflation of the lungs and the loss of elasticity in the lung tissues, which causes the chest to become rounded and the ribs to be positioned more horizontally.

Choice C rationale:

An oxygen saturation level of 96% (Choice C) is within the normal range for oxygen saturation. However, while it's important for clients with COPD to maintain adequate oxygen levels, this value doesn't specifically correlate with the client's symptoms of a wet cough and occasional shortness of breath.

Choice D rationale:

Respiratory alkalosis (Choice D) involves an increase in blood pH due to decreased levels of carbon dioxide (hypocapnia) caused by hyperventilation. While respiratory alkalosis can occur in clients with COPD due to compensatory hyperventilation, it is not a direct assessment finding related to the client's symptoms of a wet cough and occasional shortness of breath.
