The nurse is caring for a client with asthma. The client asks the nurse what structures make up the upper respiratory tract. Which response by the num the most appropriate?

To calculate the IV infusion rate in drops per minute (gtt/min), you can use the following formula:

IV infusion rate (gtt/min) =(Total volume (mL)×Drop factor (gtt/mL)) / Total time (min)

Given:

Total volume = 1000 mL

Drop factor = 10 gtt/mL

Total time = 6 hours = 6 hours × 60 minutes/hour = 360 minutes

Substitute the given values into the formula:

IV infusion rate (gtt/min) = (1000mL×10gtt/mL)/360 min

IV infusion rate (gtt/min) = 10,000/360

\(IV infusion rate (gtt/min)≈27.78gtt/min\)

Rounding to the nearest whole number, the IV infusion rate is approximately 28 gtt/min

A) Stool softener:
Stool softeners, such as docusate sodium, work by adding moisture to the stool, making it softer and easier to pass. They do not directly stimulate bowel movements or peristalsis through irritation of the bowel lining.

B) Saline/osmotic laxative:
Saline or osmotic laxatives, such as magnesium hydroxide (milk of magnesia) and polyethylene glycol (PEG), work by drawing water into the intestines, which softens the stool and increases bowel motility. They do not primarily act by irritating the bowel lining.

C) Stimulant laxative.
Stimulant laxatives work by directly stimulating the nerves in the intestines, which increases the rhythmic contractions of the intestines (peristalsis) and promotes bowel movements. These medications irritate the bowel lining, leading to increased motility and expulsion of stool. Examples of stimulant laxatives include bisacodyl and senna.

D) Bulk-forming laxative:
Bulk-forming laxatives, such as psyllium and methylcellulose, work by increasing the bulk and water content of the stool, which stimulates bowel movements. They do not directly irritate the bowel lining to promote peristalsis. Instead, they absorb water and swell in the intestines, creating a larger, softer stool that is easier to pass.
