A nurse is preparing to administer gentamicin 200 mg infusion over 1 hr to a child. Available is gentamicin 200 mg in 100 mL 0.9% sodium chloride solution. The nurse should set the IV pump to deliver how many mL per hour? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["100"]

Infusion rate (mL/hr) = Volume to be infused (mL) / Time (hr)

In this case:

Volume to be infused = 100 mL
Time = 1 hour

Plugging the values into the formula:

Infusion rate = 100 mL / 1 hour = 100 mL/hr

Correct Answer is C

Explanation

A. Magnesium 2.5 mEq/L: A magnesium level slightly above the normal range does not indicate an immediate need to discontinue clozapine, as this level is not related to the adverse effects of the drug.

B. Potassium 5.4 mEq/L: While elevated potassium levels can pose a health risk, this is not a direct indicator to discontinue clozapine. Potassium levels can be managed with other interventions.

C. WBC 2,500/mm³: Clozapine carries a risk of agranulocytosis, a condition where the white blood cell (WBC) count becomes dangerously low, leading to severe infection risk. A WBC count of 2,500/mm³ is below the normal range and indicates the need to discontinue clozapine immediately.

D. Sodium 134 mEq/L: A slightly low sodium level is not typically related to clozapine use and does not warrant discontinuation of the medication.

A. A decrease in the amount of gastric acid production B. A decrease in the frequency of defecation C. An increase in gastric motility D. An increase in the absorption of water into the intestine

Correct Answer is B

Explanation

A. A decrease in the amount of gastric acid production: Alosetron is not used to decrease gastric acid production. This effect is more associated with medications such as proton pump inhibitors or H2 blockers.

B. A decrease in the frequency of defecation: Alosetron is used to treat irritable bowel syndrome with diarrhea (IBS-D) by reducing bowel movement frequency and improving stool consistency.

C. An increase in gastric motility: Alosetron works by decreasing intestinal motility, which helps reduce diarrhea, not by increasing it.

D. An increase in the absorption of water into the intestine: Alosetron does not specifically increase water absorption into the intestine. Its primary effect is slowing intestinal transit to reduce diarrhea.
