A nurse is preparing to administer oxygen to a client who has heart failure and is having severe difficulty breathing. Which of the following oxygen delivery equipment should the nurse select to provide the highest concentration of oxygen to the client?
Nasal cannula
Simple face mask
Venturi mask
Nonrebreather mask
The Correct Answer is D
A: A nasal cannula provides a low to moderate concentration of oxygen and is not suitable for a client experiencing severe difficulty breathing.
B: A simple face mask provides a higher concentration of oxygen than a nasal cannula but may not deliver a high enough concentration for a client experiencing severe respiratory distress.
C: A Venturi mask can provide a precise and adjustable concentration of oxygen but may not deliver the highest concentration needed in this scenario.
D: A nonrebreather mask can deliver the highest concentration of oxygen (up to 100%) and is the most appropriate choice for a client experiencing severe difficulty breathing.

Correct Answer is C
Explanation
A. Remove dentures:
- Removing dentures is a step often performed during post-mortem care but may not necessarily need to be completed before family viewing, especially if the dentures are normally worn by the deceased.
B. Apply a shroud around the body with a visible identification tag:
- Applying a shroud with a visible identification tag is an important step for dignified covering and identification but might be more appropriate after the family has viewed the body.
C. Clean soiled areas of the body:
- This is the most appropriate action to ensure the body appears as dignified and comfortable as possible for family viewing. It involves cleaning any visible soiled areas to provide a respectful presentation to the family.
D. Place the client's head in a dependent position:
- Placing the client's head in a dependent position is not typically necessary or recommended in this context. The goal is to ensure the body appears as natural and dignified as possible.
Correct Answer is A
Explanation
A: Correct. Checking the pH of the gastric aspirate is the most reliable method to verify the correct placement of the NG tube. Gastric aspirate typically has an acidic pH (pH < 5), indicating that the tube is in the stomach.
B: Observing the color of the gastric aspirate after adding blue dye to the formula is not a standard or recommended method for verifying NG tube placement.
C: Auscultating over the epigastrium may help to identify the presence of air in the stomach, but it does not confirm that the NG tube is correctly placed in the stomach or the intestines.
D: Measuring the length of the inserted NG tube can help determine the distance from the nose to the stomach, but it does not ensure correct placement in the stomach.
