A nurse is caring for a client who must take a liquid cough syrup and several other oral tablets at the same time. What nursing action is most appropriate when administering both types of oral medications to this client?

A. Active transport requires energy and is used to move substances against their concentration gradient. Oxygen moves along its concentration gradient, so active transport is not involved.
B. Diffusion is the correct mechanism. Oxygen moves from an area of higher concentration in the alveoli to a lower concentration in the pulmonary capillaries through the alveolar-capillary membrane. This passive process does not require energy.
C. Endocytosis is a process cells use to engulf large particles or substances, not how gases like oxygen are transported.
D. Pinocytosis is a form of endocytosis specifically for fluid uptake and is not involved in the respiratory gas exchange process

A. Compliant is not the term used in COPD. It refers to something that is flexible or yielding, which does not describe the condition.
B. Cumulative could describe the long-term effects of COPD, but it is not the word represented by the "C" in COPD.
C. Congestive is a term often associated with conditions like congestive heart failure, not COPD.
D. Chronic is the correct term. Chronic Obstructive Pulmonary Disease (COPD) refers to a long-term, progressive lung disease that causes difficulty breathing due to airflow obstruction.
