Full Explanation
Step 1: Determine the Medication Concentration
- The total amount of medication in the solution is 250 mg.
- The total volume of the solution is 5 mL.
- To find the concentration per mL:
250 mg ÷ 5 mL = 50 mg/mL
Step 2: Determine the Required Volume
- The prescribed dose is 500 mg.
- To find the volume needed:
500 mg ÷ 50 mg/mL = 10 mL
Thus, the nurse should administer 10 mL of the solution to deliver the required 500 mg dose.

A nurse is monitoring a client's IV site.
The nurse should report which of the following findings as manifestations of phlebitis? (Select all that apply.).
A. Blistering around the insertion site.
Blistering around the insertion site is not a common sign of phlebitis. It could indicate a more severe complication like extravasation or infiltration.
B. Streak formation along the vein.
Streak formation along the vein is a classic sign of phlebitis. It indicates inflammation and possible infection.
C. Erythema at the insertion site.
Erythema at the insertion site is another common sign of phlebitis. It indicates inflammation.
D. Warmth at insertion site.
Warmth at the insertion site is also a common sign of phlebitis. It is caused by increased blood flow to the area due to inflammation. So, the correct answers are B, C, and D.

A nurse is preparing to administer 0.9% sodium chloride (NaCl) 750 mL IV to infuse over 8 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number.
Use a leading zero if it applies.
Full Explanation
Step 1 is to calculate the rate of infusion. The formula is total volume ÷ total time. So, (750 mL ÷ 8 hr) = 93.75 mL/hr. Rounding to the nearest whole number gives 94 mL/hr.
So, the correct answer is 94 mL/hr.
A nurse is preparing to administer amoxicillin 300 mg PO. The amount available is amoxicillin oral solution 250 mg/5 mL.
How many mL should the nurse administer?
(Round the answer to the nearest tenth/whole number. Use a leading zero if it applies.)
Full Explanation
Step 1 is to calculate the volume of medication to administer. The formula is desired dose ÷ available dose × available volume. So, (300 mg ÷ 250 mg) × 5 mL = 6 mL.
So, the correct answer is 6 mL.
