A nurse is helping to place a client into the prone position.

The nurse should use a small pillow to relieve pressure from which of the following areas of the client's body?

A. Opening the dampers of fireplaces: This instruction is not appropriate during an outdoor chemical disaster. Opening the dampers of fireplaces can allow contaminated air from outside to enter the home, increasing exposure to hazardous substances. It is best to avoid introducing outdoor air into the home during such incidents.

B. Turning on ceiling fans and air conditioners: This instruction is also not recommended during an outdoor chemical disaster. Turning on fans and air conditioners can potentially circulate contaminated air within the home, leading to increased exposure. It is best to turn off fans and air conditioners during such incidents and focus on evacuating the area.

C. Covering heat registers with plastic and tape:This would help seal the house and prevent contaminated air from entering through heating vents.

D. While evacuation is essential in some situations (such as fires), it’s not the first step during a chemical disaster.​​​​​Immediate evacuationmay not be safe if the outdoor environment is hazardous. First, take protective measures within the home.

Informed consent is a legal and ethical requirement for certain medical procedures. It involves providing the client with clear and comprehensive information about the procedure, including its risks, benefits, alternatives, and expected outcomes. The client must understand the information provided and voluntarily give their consent before the procedure can be performed.

Placement of a central venous catheter is an invasive procedure that carries risks and potential complications, making it necessary to obtain informed consent from the client.

Wound irrigation with an antibiotic solution is a standard nursing intervention for wound care and does not usually involve invasive procedures. Informed consent is not typically required for this procedure.

The administration of an iron injection using the Z-track technique is a standard nursing procedure. While it involves an injection, it is not typically considered an invasive procedure that would require informed consent.

Insertion of a nasogastric tube is a common procedure that involves passing a tube through the nose and into the stomach for various purposes, such as feeding, decompression, or medication administration. While it is an invasive procedure, it is often performed in emergency or critical care situations where the client's immediate well-being takes precedence. Informed consent may not be feasible or necessary in these situations, depending on the context and urgency.
