The nurse starts her shift at the urgent care clinic. Which of the following patients should she assess first? A) A 46 yo female complaining of abdominal pain B) A 22 yo male with a heart rate of 50 complaining of a headache C) A 2 month old with a respiratory rate of 65 who has not had a wet diaper in 6 hours D) A child with type 1 diabetes and a blood sugar of 140.
The answer is C. A respiratory rate of 65 is outside of normal limits for a 2 month old. Issues pertaining to the ABCs (Airway, Breathing, Circulation) should be assessed first. Additionally, 2 month old children should have a wet diaper every 4-5 hours. Any less could indicate dehydration, which can become a serious problem in the infant population if not addressed quickly.

A patient is ordered to receive 10mg of a medication. The liquid medication is available as 2.5 mg/ 2 mL. How many mLs need to be dispensed to ensure the proper dose is given?
The general formula is "want" / "have" * volume. In this case, we want 10 mg of medication. We have 2.5mg of medication in every 2 mL of liquid. Plugging those numbers into the formula gives us 10 mg / 2.5 mg * 2mL. Breaking this down we get 10 mg / 2.5 mg = 4 . We then finish out the formula 4 * 2mL = 8mL. Our final answer is 8mL.
What is the difference between Criterion-Referenced tests and Norm-Referenced tests?
Criterion-referenced tests use an absolute standard of performance for grading purposes. This means the tests will never use a sliding scale or be "curved". Norm-Referenced tests are designed with a flexible grading scale and are often referred to as "curved".
