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 A
Explanation
Type 1 diabetes mellitus is a condition where the body's immune system mistakenly attacks and destroys the insulin-producing cells in the pancreas. Individuals with type 1 diabetes require insulin therapy to manage their blood sugar levels. Since the question is about teaching an adolescent with type 1 diabetes, let's analyze each option:
A) Obtain an influenza vaccine annually:
This is a crucial recommendation. People with diabetes, including type 1 diabetes, have a higher risk of complications from infections, including influenza (the flu). The flu can lead to elevated blood sugar levels and potentially worsen diabetes control. Getting an annual influenza vaccine helps reduce the risk of getting the flu and its associated complications.
B) Take glyburide with breakfast:
Glyburide is a medication used to treat type 2 diabetes, not type 1 diabetes. It stimulates the pancreas to produce more insulin. Type 1 diabetes is characterized by a lack of insulin production, so taking glyburide would not be appropriate.
C) Administer glucagon for hyperglycemia:
Glucagon is a hormone used to raise blood sugar levels, typically in cases of severe hypoglycemia (low blood sugar). It is not used to treat hyperglycemia (high blood sugar) in type 1 diabetes. Instead, insulin administration is the primary method for managing high blood sugar levels.
D) Inject insulin in the deltoid muscle:
Insulin injections for individuals with type 1 diabetes are typically given in the subcutaneous fat, which is found just beneath the skin. The deltoid muscle is not a recommended site for insulin injections due to inconsistent absorption. The abdomen, thighs, and buttocks are commonly recommended injection sites.
Correct Answer is B
Explanation
A) Document intake and output:
Documenting intake and output is an important nursing task, but it is not the top priority in a suspected case of bacterial meningitis. Timely administration of antibiotics to treat the infection takes precedence over documentation of intake and output.
B) Administer antibiotics when available.
Explanation:
Bacterial meningitis is a serious and potentially life-threatening infection of the membranes covering the brain and spinal cord. Rapid administration of antibiotics is crucial to effectively treat the infection and prevent its spread. Delay in antibiotic administration can lead to worsening symptoms and complications. Therefore, getting the appropriate antibiotics to the child as soon as they are available is the nurse's priority.
C) Reduce environmental stimuli:
Reducing environmental stimuli can be helpful in managing symptoms and providing comfort to the child with meningitis, but it is not the priority action. The immediate concern in a suspected case of bacterial meningitis is to treat the infection.
D) Maintain seizure precaution:
While maintaining seizure precautions is important, especially if the child has a history of seizures, it is not the top priority in a suspected case of bacterial meningitis. Administering antibiotics to treat the infection and prevent its progression is the primary concern.
