A nurse is preparing to administer amoxicillin 250 mg PO. Available is amoxicillin oral suspension 125 mg/5 mL. How many ml. should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. "I should decrease my physical activity." Decreasing physical activity is not recommended as it can worsen constipation. Physical activity helps stimulate bowel movements, so this statement does not indicate proper understanding.
B. "I should increase fluid intake." Increasing fluid intake helps to soften the stool and promote bowel movements. Adequate hydration is essential in managing constipation, especially when taking opioids.
C. "I should only take a laxative when necessary." Taking a laxative only when necessary is a reasonable approach to managing constipation. Overuse of laxatives can lead to dependency and should be avoided. Using them judiciously can help manage symptoms effectively.
D. "I should increase fiber intake." Increasing dietary fiber can help to bulk up the stool and stimulate bowel movements, which is beneficial in preventing and treating constipation associated with opioid use.
E. "I should strain when I try to have a bowel movement." Straining during bowel movements is not recommended as it can lead to complications such as hemorrhoids or anal fissures. This statement indicates a misunderstanding of proper bowel habits.

A. The nose and paranasal sinuses: This is partially correct, but it does not include all the structures of the upper respiratory tract. It misses the nasal cavity and the pharynx.
B. The nose, nasal cavity, pharynx, and the lungs: This is incorrect because the lungs are part of the lower respiratory tract, not the upper respiratory tract.
C. The nose, nasal cavity, pharynx, and paranasal sinuses: This is the correct answer. The upper respiratory tract includes the nose, nasal cavity, pharynx, and paranasal sinuses. These structures are involved in air conduction, filtration, humidification, and protection.
D. The lungs and associated structures: This is incorrect as the lungs are part of the lower respiratory tract, which also includes the bronchi and bronchioles.
