A nurse is preparing to administer potassium chloride elixir 20 mEq/day PO to divide equally every 12 hr. Available is 6.7 mEq/5 mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["7.5"]
The correct answer is 7.5 ML
To answer this question, we need to use the formula:
mL to administer = (mEq ordered / mEq available) x mL available Plugging in the values from the question, we get:
mL to administer = (20 mEq/day / 6.7 mEq/5 mL) x 5 mL Simplifying, we get:
mL to administer = (2.99 mL/mEq) x 5 mL Multiplying, we get:
mL to administer = 14.95 mL/day
Since the order is to divide the dose equally every 12 hours, we need to divide the total daily dose by 2:
mL to administer per dose = 14.95 mL/day / 2 Dividing, we get:
mL to administer per dose = 7.475 mL
Rounding to the nearest tenth, we get:
mL to administer per dose = 7.5 mL
Therefore, the nurse should administer 7.5 mL of potassium chloride elixir per dose.

Correct Answer is B
Explanation
Choice A rationale:
Red man syndrome is associated with vancomycin, not phenytoin.
Choice B rationale:
Hypotension, or low blood pressure, can be an adverse effect of phenytoin.
Choice C rationale:
Hypoglycemia is not a typical adverse effect of phenytoin.
Choice D rationale:
Bradycardia is not a common adverse effect of phenytoin.
Correct Answer is C
Explanation
Choice A rationale:
Testing negative for HIV does not mean that the client is taking the antibiotics as prescribed. HIV is a virus that weakens the immune system and makes people more susceptible to tuberculosis, but it is not related to the medication regimen for tuberculosis.
Choice B rationale:
having a positive purified protein derivative test does not mean that the client is taking the antibiotics as prescribed. A purified protein derivative test is a skin test that checks for exposure to tuberculosis bacteria, but it does not measure the effectiveness of the medication regimen. A positive test means that the client has been exposed to tuberculosis bacteria at some point in their life, but it does not mean that they have an active infection or that they are taking the antibiotics as prescribed.
Choice C rationale:
The client has a negative sputum culture. A sputum culture is a test that checks for the presence of tuberculosis bacteria in the mucus that is coughed up from the lungs. A negative sputum culture means that the bacteria are no longer detectable and that the medication regimen is effective. A positive sputum culture means that the bacteria are still present and that the medication regimen may need to be adjusted.
Choice D rationale:
Having normal liver function test results does not mean that the client is taking the antibiotics as prescribed. Liver function tests are blood tests that check for damage to the liver caused by medications or other factors. Isoniazid and rifampin can cause liver damage, so the nurse should monitor the client's liver function tests regularly to prevent or detect any problems. However, having normal liver function test results does not mean that the client is taking the antibiotics as prescribed or that the medication regimen is effective.
