A patient has difficulty in breathing. The nurse provides oxygen therapy to the patient, after which the patient feels better. Which principle is involved in this situation?

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:

This choice is not correct because verifying the oxygen flow rate every other day is not part of the discharge teaching for a client on home oxygen therapy. The flow rate should be checked regularly, not just every other day, to ensure the client's safety and well-being.

Choice B rationale:

This choice is correct. Checking the tops of the ears for skin breakdown is important in a client using a nasal cannula for oxygen therapy. Prolonged use of the cannula can lead to irritation and pressure-related skin breakdown behind the ears.

Choice C rationale:

This choice is correct. Posting "no smoking signs in a prominent location in the home" is an important safety measure for a client on oxygen therapy. Oxygen supports combustion, and smoking in the presence of oxygen can lead to fire hazards.

Choice D rationale:

This choice is correct. Checking the cannula position on a regular basis is essential to ensure that the oxygen is being delivered effectively and that the client is not experiencing discomfort or skin breakdown due to improper positioning.

Choice E rationale:

This choice is correct. Applying petroleum ointment to the nares if they become dry and irritated is a suitable intervention to maintain the client's comfort and prevent skin irritation from the cannula.
