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."
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 ["A","B","C","D"]
Explanation
A. Dyspnea: Shortness of breath or difficulty breathing is a hallmark symptom of COPD, commonly reported by patients.
B. Chronic cough: A persistent cough, often productive, is a common manifestation of COPD, reflecting the chronic inflammation and irritation of the airways.
C. Wheezing: Wheezing, a high-pitched whistling sound during breathing, is often present in COPD due to airway narrowing and obstruction.
D. Sputum production: Increased production of sputum (mucus) is typical in COPD, as the chronic inflammation leads to mucus hypersecretion.
E. Chest tightness: While chest tightness can occur in COPD, it is less common compared to the more prominent symptoms of dyspnea, chronic cough, wheezing, and sputum production.
Correct Answer is C
Explanation
A. Avoid vitamin supplements during therapy: This is not generally advised for isoniazid therapy. In fact, vitamin B6 supplements are often recommended to prevent peripheral neuropathy caused by isoniazid.
B. Drink alcohol in small amounts only: Alcohol can increase the risk of liver toxicity when taking isoniazid. It is typically advised to avoid alcohol altogether during treatment.
C. Report yellow eyes or skin immediately: Isoniazid can cause liver toxicity, which can lead to jaundice (yellowing of the eyes and skin). This is a serious side effect and should be reported immediately to prevent further liver damage.
D. Increase intake of Swiss or aged cheeses: This recommendation is not related to isoniazid therapy. Aged cheeses are more relevant to patients on monoamine oxidase inhibitors (MAOIs) due to tyramine content.
