A patient’s hemoglobin is severely low and she is complaining of being overly tired and fatigued. You are educating her on the role hemoglobin has with oxygenation and perfusion. You will know she understands the role of hemoglobin when she tells you hemoglobin transports:

Explanation: In clients with COPD, the secretions tend to be thick and sticky, which makes it difficult to cough up and clear the airway. To promote respiratory hygiene in this situation, the nurse should recommend increasing fluid intake. Adequate hydration helps to thin the secretions, making them easier to expectorate. The client should aim to drink at least 8-10 glasses of water or other fluids per day unless there is a medical reason not to do so.

Decreasing fluid intake (option a) would make the secretions even thicker and more difficult to clear. Taking Tylenol for secretions (option b) is not a recommended intervention as Tylenol is not indicated for thinning of secretions. Range-of-motion exercises (option c) are important to prevent complications such as pneumonia, but they are not directly related to promoting respiratory hygiene in this situation.

Explanation: Central venous catheters are catheters that are inserted through a vein in the chest, neck, or groin and then threaded through to a large vein near the heart. These types of catheters are used for long- term treatment and monitoring of critically ill patients.

A midline catheter is a type of peripheral IV catheter that is longer and extends into the upper arm, but it does not reach a central vein and is not considered a central line. Therefore, option a. is incorrect.

A peripheral IV catheter is inserted into a peripheral vein (e.g., hand, arm), and it does not reach a central vein, making it a peripheral line. Therefore, option d. is incorrect.

A tunneled catheter is a type of central venous catheter that is inserted through a small incision in the chest and then tunneled under the skin to a central vein. It is typically used for long-term treatment and is less likely to become infected than a non-tunneled catheter. Therefore, option b. is correct.

A non-tunneled catheter is a type of central venous catheter that is inserted directly into a central vein in the chest, neck, or groin. It is typically used for short-term treatment and is more likely to become infected than a tunneled catheter. Therefore, option c. is correct.

A PICC line (peripherally inserted central catheter) is a type of central venous catheter that is inserted through a vein in the arm and then threaded through to a central vein near the heart. It is typically used for long-term treatment and is less invasive than other types of central lines. Therefore, option e. is correct.
