A nurse practitioner orders 1 liter of 0.9% normal saline to infuse over 6 hours. How many milliliters per hour will the nurse program the IV infusion device? Round off.
160 ml/hr
125 ml/hr
100 ml/hr
167 ml/hr
The Correct Answer is D
To calculate the milliliters per hour (mL/hr) for the IV infusion, you divide the total volume (in milliliters) by the total time (in hours).
In this case, the total volume is 1 liter, which is equal to 1000 milliliters, and the total time is 6 hours.
So, you divide 1000 mL by 6 hours:
1000 mL / 6 hours = 166.67 mL/hr
Rounding off, the nurse will program the IV infusion device to infuse at approximately 167 mL/hr.

Explanation
1. Alcohol: Alcohol can relax the LES, leading to increased reflux symptoms. 2. Chocolate: Chocolate contains compounds that can relax the LES and contribute to reflux symptoms.
3. Peppermint: Peppermint, including peppermint oil and peppermint-flavored foods, can relax the LES and worsen reflux symptoms.
4. Citrus fruits: Citrus fruits and juices, such as oranges, grapefruits, and lemons, are acidic and can irritate the esophagus, exacerbating GERD symptoms.
5. Cola sodas: Cola sodas, including both regular and diet varieties, can contribute to reflux symptoms due to their carbonation and acidic content.
6. Fatty foods: High-fat foods, such as fried foods, fatty meats, and full-fat dairy products, can delay stomach emptying and increase pressure on the LES, leading to reflux.
Correct Answer is B
Explanation
Gentamicin is an antibiotic that is usually administered via IV infusion. The peak level is the highest concentration of the medication in the bloodstream, and it is important to monitor it to ensure therapeutic levels are achieved without reaching toxic levels.
Drawing the peak level 30 minutes after the infusion is complete allows enough time for the medication to distribute throughout the body and reach its peak concentration. This timing provides an accurate representation of the highest drug concentration in the bloodstream. 30 minutes before starting the infusion: Drawing the peak level before starting the infusion would not accurately reflect the peak concentration of the medication in the bloodstream. Immediately before the next dose of Gentamicin: Drawing the peak level immediately before the next dose would not provide an accurate assessment of the highest drug concentration, as the levels would have started to decrease due to elimination.
1 hour after infusion is complete: Waiting for 1 hour after the infusion is complete may result in missing the actual peak concentration of the medication in the bloodstream, as it may have already started to decline.
