A nurse is preparing to administer vancomycin 15 mg/kg/day divided equally every 12 hr. The client weighs 198 lb. How many mg should the nurse administer With each dose? (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 ["675"]

- 198 lb ÷ 2.205 lb/kg = 90 kg
Calculate the total daily dose:
- 15 mg/kg/day * 90 kg = 1350 mg/day
Calculate the dose for each 12-hour period:
- 1350 mg/day ÷ 2 doses/day = 675 mg/dose

Correct Answer is C

Explanation

Rationale-Blood is considered an isotonic solution because its solute concentration is similar to that of the cells in the body, allowing for free movement of water across cell membranes without causing a net influx or efflux of water. This isotonic nature is crucial for maintaining cell integrity and function.

Isotonic solutions have the same osmotic pressure as body’s plasma

B-Hypertonic solution like 3% saline have higher osmotic pressure compared to plasma. This type of solutions draw water from the cells causing shrinkage

D-Hypotonic solution like 0.45% saline have lower osmotic pressure as compared to plasma. They cause swelling of cells with eventual damage

A. Magnesium 1.9 mEq/L B. Potassium 3.6 mEq/L C. Chloride 99 mEqJL D. Sodium 126 mEq/L

Correct Answer is D

Explanation

The lab value that should be reported to the provider is D. Sodium 126 mEq/L. Normal sodium levels are typically between 135 and 145 mEq/L. A sodium level of 126 mEq/L is considered hyponatremia, which is a lower-than-normal concentration of sodium in the blood. Hyponatremia can have various causes and may result in symptoms such as headache, confusion, seizures, and other serious health issues.

A-Normal magnesium levels – 1.7-2.2 mEq/L

B-Normal potassium levels- 3.5-5.5mEq/L

C-Normal chloride levels- 96-106 mEq/L
