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
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 A
Explanation
A. The P wave represents atrial depolarization, which is initiated by the SA node, the heart's natural pacemaker.
B. The AV node is responsible for conducting impulses from the atria to the ventricles but does not initiate the P wave.
C. The Bundle of His transmits the electrical impulses to the ventricles but is not directly associated with the P wave.
D. Purkinje fibers are involved in ventricular depolarization, which corresponds to the QRS complex, not the P wave.
Correct Answer is B
Explanation
A. The definition of spirituality does not typically include concepts of fire or giving life; this option does not accurately capture the essence of spirituality.
B. Awareness of one's inner self encompasses the essence of spirituality, focusing on personal beliefs, values, and the search for meaning, which is widely recognized in health care.
C. Spirituality is often considered equally essential to physical needs, especially in holistic approaches to health and well-being, making this statement misleading.
D. Spirituality can have a significant impact on health, influencing coping mechanisms and overall well-being; therefore, labeling it as having a minor effect is not accurate.
