A patient is experiencing carbon dioxide retention from lung problems. Which type of diet will the nurse most likely suggest for this patient?

Moderate-carbohydrate

Low-caffeine

High-carbohydrate

High-caffeine

Answer and Explanation

The Correct Answer is A

A. A moderate-carbohydrate diet is recommended because carbohydrates increase CO₂ production during metabolism, and limiting excessive carbohydrate intake can help manage CO₂ retention in patients with respiratory issues.
B. Low-caffeine is not directly related to CO₂ retention and does not influence carbon dioxide levels in the body.
C. High-carbohydrate intake can exacerbate CO₂ production, worsening retention issues in patients with compromised lung function.
D. High-caffeine intake is not related to CO₂ retention management and would not impact CO₂ levels in the respiratory system.

Correct Answer is C

Explanation

A. Elevated blood pressure may occur with various conditions but is not a specific late sign of hypoxia.
B. An increased pulse rate can be an early compensatory response to hypoxia rather than a late sign.
C. Cyanosis, which is a bluish discoloration of the skin and mucous membranes, is a classic late sign of hypoxia, indicating severe oxygen deprivation.
D. Restlessness may indicate early signs of hypoxia or anxiety rather than a late sign and can occur before cyanosis develops.

A. Give the injection and hold pressure over the site for 3 minutes. B. Administer the injection at a slower rate. C. Withdraw the needle and prepare the injection again. D. Pull the needle back slightly and inject the medication.

Correct Answer is C

Explanation

A. Continuing with the injection after seeing blood return increases the risk of injecting into a blood vessel, which is not safe for IM injections.
B. Administering at a slower rate does not address the issue of possible intravascular injection.
C. If blood is aspirated, the correct procedure is to withdraw the needle, dispose of the medication, and prepare a new dose to prevent intravascular administration, as IM injections are meant to be given into muscle tissue, not into a vein.
D. Pulling the needle back slightly is not recommended because it does not ensure that the needle is completely out of the blood vessel.
