A charge nurse is reinforcing teaching to a group of nurses about diffusion. Which of the following statements should the charge nurse include in their teaching about diffusion?

"Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration."

"Diffusion is the movement of particles between areas of equal concentrations."

"Diffusion is the movement of water from an area of higher concentration of water to an area of lower concentration of water."

"Diffusion is the movement of particles from an area of lower concentration of particles to an area of higher concentration of particles."

Answer and Explanation

The Correct Answer is A

A. "Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.": This statement accurately describes diffusion. Molecules move down their concentration gradient from areas of higher concentration to areas of lower concentration until equilibrium is reached.

B. "Diffusion is the movement of particles between areas of equal concentrations.": Diffusion does not occur between areas of equal concentration as there is no concentration gradient to drive the movement.

C. "Diffusion is the movement of water from an area of higher concentration of water to an area of lower concentration of water.": This describes osmosis, not diffusion. Osmosis specifically refers to the movement of water across a semipermeable membrane.

D. "Diffusion is the movement of particles from an area of lower concentration of particles to an area of higher concentration of particles.": This is incorrect as diffusion occurs from higher to lower concentration, not the reverse.

Correct Answer is D

Explanation

A. ARDS is characterized by severe hypoxemia due to shunting, but it typically impairs oxygenation rather than carbon dioxide elimination. The primary issue is the inability to oxygenate blood, not the elimination of carbon dioxide.
B. In ARDS, pulmonary arterial pressure often increases due to pulmonary hypertension caused by widespread inflammation and hypoxemia, not decreased pressure. V/Q mismatch contributes to hypoxemia but does not directly cause decreased pulmonary arterial pressure.
C. While hypoxemia is a hallmark of ARDS, it is primarily due to shunting (where blood passes through unventilated areas of the lung) rather than dead space, which is more associated with conditions like pulmonary embolism.
D. ARDS involves decreased pulmonary compliance due to the stiffness of the lungs, which results from diffuse alveolar damage and the formation of hyaline membranes. This stiffness makes it difficult for the lungs to expand, leading to reduced oxygenation and severe hypoxemia.

A. Bronchospasm occurs when there is inflammation, edema, and excess mucus. B. Decreased mucus production contributes to airway constriction. C. Inflammation is reduced due to airway diameter. D. Airway obstruction occurs due to thinning mucus.

Correct Answer is A

Explanation

A. Bronchospasm occurs when there is inflammation, edema, and excess mucus: Bronchospasm in asthma is characterized by inflammation of the airways, edema of the airway walls, and increased mucus production, leading to constriction and obstruction of the airways.

B. Decreased mucus production contributes to airway constriction: In asthma, bronchospasm is associated with increased mucus production, not decreased. Excess mucus contributes to airway obstruction.

C. Inflammation is reduced due to airway diameter: Inflammation typically increases airway constriction rather than reducing it. The narrowed airway diameter is a result of inflammation, not a reduction in inflammation.

D. Airway obstruction occurs due to thinning mucus: Airway obstruction in asthma is due to thick, tenacious mucus, not thinning mucus. The mucus contributes to the blockage of the airways.
