The healthcare provider prescribes amoxicillin 5 grams PO daily, in equally divided doses to be administered every 8 hours. The medication is available in a bottle labeled, "Amoxicillin suspension 200 mg/5 mL."
How many mL should the nurse administer every 8 hours?
(Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["41.7"]
Step 1: Convert grams to milligrams
The prescribed dose is 5 grams (g) daily.
- 1 gram (g) = 1,000 milligrams (mg)
- 5 g = 5,000 mg daily
Step 2: Determine the dose per administration
The medication is to be given every 8 hours, meaning the total daily dose is divided into three equal doses:
5,000 mg/3=1,666.67 mg per dose
Step 3: Use the medication concentration to find the volume
The available suspension is 200 mg per 5 mL. Using the ratio formula:
200 mg/5 mL=1,666.67 mg/X mL
Solve for X:
X=1,666.67×5/200
X=8,333.35/200=41.67 mL
Answer: 41.7 mL (Rounded off to the nearest tenth)

Explanation
A. "Hyperglycemia often results in weight loss.": Weight loss is more commonly associated with prolonged hyperglycemia, particularly in uncontrolled diabetes where the body starts breaking down fat and muscle for energy.
B. "Hyperglycemia causes cool and clammy skin.": Cool and clammy skin is more indicative of hypoglycemia (low blood sugar) rather than hyperglycemia.
C. "Hyperglycemia causes an increased sensation of being hungry.": Increased hunger is often associated with hypoglycemia or uncontrolled diabetes, where insulin is not effectively managing blood glucose levels.
D. "Hyperglycemia causes a headache and flushed, dry skin.": In cases of significant hyperglycemia, symptoms can include headache and flushed, dry skin due to dehydration. These symptoms arise from the body’s attempt to balance blood sugar levels and manage dehydration.
E. "Hyperglycemia often presents as increased thirst and urination.": Hyperglycemia typically leads to increased thirst (polydipsia) and increased urination (polyuria). This occurs because the body tries to get rid of excess glucose through the urine, leading to dehydration and increased thirst.
