A nurse is preparing to administer amoxicillin 30 mg/kg/day divided equally every 12 hr to a toddler who weighs 33 lb. Available is amoxicillin 200 mg/5 mL suspension. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["5.625"]
To calculate the dose of amoxicillin for the toddler:
Step 1: Convert the toddler's weight from pounds to kilograms.
33 lb ÷ 2.2 (lb to kg conversion factor) = approximately 15 kg
Step 2: Calculate the total daily dose of amoxicillin.
Dose = 30 mg/kg/day × 15 kg = 450 mg/day
Step 3: Divide the total daily dose into equal doses every 12 hours.
450 mg/day ÷ 2 doses = 225 mg/dose
Step 4: Calculate the amount of amoxicillin suspension needed for each dose.
The available concentration is 200 mg/5 mL, so for 225 mg, you would use the proportion:
225 mg : 200 mg = x mL : 5 mL
Cross-multiplying: x = (225 mg × 5 mL) / 200 mg ≈ 5.625 mL
Therefore, the nurse should administer approximately 5.625 mL of amoxicillin suspension for each dose.

Correct Answer is D
Explanation
A. Polyuria (excessive urination) is not a symptom of hypoglycemia; it is more commonly associated with hyperglycemia (high blood sugar).
B. Deep rapid respirations are more characteristic of diabetic ketoacidosis (DKA), a complication of uncontrolled diabetes that leads to high blood sugar levels and metabolic acidosis.
C. Dry, flushed skin is not a typical symptom of hypoglycemia; it might be associated with conditions like dehydration or heat exposure, but not with low blood sugar.
D. Tachycardia
Explanation: The symptoms described by the adolescent (feeling shaky, difficulty speaking, difficulty concentrating) along with a blood glucose level of 55 mg/dL indicate hypoglycemia, which is low blood sugar. Tachycardia, or a rapid heart rate, is a common physiological response to hypoglycemia. The body increases the heart rate in an attempt to improve blood flow and deliver glucose to the brain and other vital organs. This is part of the body's fight-or-flight response to low blood sugar.
Correct Answer is A
Explanation
A. Levothyroxine
Correct Answer: Levothyroxine should be administered before breakfast.
Explanation: Levothyroxine is a synthetic thyroid hormone used to treat hypothyroidism. It needs to be taken on an empty stomach, at least 30 minutes before eating, to ensure proper absorption. Food can interfere with its absorption, especially foods containing calcium, iron, and fiber.
B. Digoxin
Incorrect Explanation: Digoxin does not need to be administered before breakfast.
Explanation: Digoxin is a medication used to treat heart conditions like congestive heart failure and atrial fibrillation. It doesn't have specific instructions regarding administration in relation to meals. It's important to administer digoxin consistently at the same time every day, but it doesn't need to be taken specifically before or after breakfast.
C. Divalproex
Incorrect Explanation: Divalproex does not need to be administered before breakfast.
Explanation: Divalproex is used to treat conditions like epilepsy and bipolar disorder. It can be taken with or without food. While taking it with food might reduce the likelihood of stomach upset, there's no requirement to take it specifically before breakfast.
D. Mycostatin Mouthwash
Incorrect Explanation: Mycostatin mouthwash is not related to breakfast timing.
Explanation: Mycostatin is an antifungal medication used to treat fungal infections in the mouth (oral thrush). Its administration is not linked to meal times. It's typically swished around in the mouth and then swallowed or spit out, depending on the specific instructions provided by the healthcare provider.
