The healthcare provider prescribes cefixime oral suspension 200 mg by mouth twice a day for an older adult who has difficulty swallowing pills. The bottle is labeled, "Cefixime for Oral Suspension, USP 100 mg per 5 mL." How many mL should the nurse administer daily? (Enter numerical value only.)

Answer and Explanation

The Correct Answer is ["20"]

To calculate the total daily dose, we first need to determine the dose per administration:

Desired dose = 200 mg/dose
Concentration = 100 mg/5 mL

Volume (mL) = Desired dose (mg) / Concentration (mg/mL)

Volume = 200 mg / (100 mg/5 mL) = 10 mL

Now, calculate the total daily volume:

10 mL/dose 2 doses/day = 20 mL/day

Correct Answer is B

Explanation

A. The use of "2.0 mg" is incorrect because trailing zeros can lead to dosage errors. The correct documentation should avoid trailing zeros to prevent misinterpretation.
B. "Morphine 2 mg IV every 4 hr PRN for severe pain" is the correct format. It uses the full name of the drug, avoids abbreviations that could be confused, and follows best practices for documenting as-needed (PRN) medications.
C. Using "MS" instead of "morphine" is not recommended because "MS" can be confused with magnesium sulfate or other medications. The full drug name should always be used.
D. Similar to option A, the use of "2.0 mg" includes a trailing zero, which should be avoided to reduce the risk of errors in medication administration.

A. White blood cell count. B. Serum sodium levels. C. Serum potassium levels. D. Creatinine clearance.

Correct Answer is B

Explanation

A. White blood cell count is related to immune function and is not directly affected by water intoxication.
B. Serum sodium levels are the primary concern in cases of water intoxication. Excessive water intake can dilute the sodium in the blood, leading to hyponatremia, which can cause confusion, seizures, and other serious complications.
C. While serum potassium levels are important for overall electrolyte balance, they are not as immediately affected by water intoxication as sodium levels are.
D. Creatinine clearance is a measure of kidney function and does not directly relate to the immediate risks associated with water intoxication.
