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"]
To calculate the amount of potassium chloride elixir needed per dose, we can use the following formula:
Amount per dose (mL) = (Desired dose in mEq / Concentration in mEq/mL) * Volume in mL
Given:
Desired dose = 20 mEq/day divided equally every 12 hr = 10 mEq/dose
Concentration = 6.7 mEq/5 mL
Plugging in the values:
Amount per dose (mL) = (10 mEq / 6.7 mEq/5 mL) * 5 mL
Calculating:
Amount per dose (mL) ≈ 7.46 mL
Rounded to the nearest tenth, the nurse should administer approximately 7.5 mL of the potassium chloride elixir per dose.

Correct Answer is C
Explanation
A. Instruct the client to increase his fluid intake: While adequate fluid intake is generally important for various reasons, increasing fluid intake would not alter the orange-red discoloration caused by rifampin. This side effect is due to the drug's action on body fluids, not dehydration.
B. Prepare the client for dialysis: Dialysis is not indicated for the harmless orange-red discoloration caused by rifampin. Dialysis is typically used for clients with kidney failure or significant electrolyte imbalances, and it would not address this specific side effect.
C. Document this as an expected finding.
Explanation:
Rifampin, an antibiotic commonly used in the treatment of tuberculosis (TB), can cause a harmless side effect known as "orange-red discoloration." This can affect bodily fluids such as urine, sweat, and tears. This is not a harmful effect and does not indicate a need for any specific intervention. Therefore, the nurse should document this as an expected finding due to the client's use of rifampin.
D. Check the client's liver function test results: The orange-red discoloration is not related to liver function, so checking liver function test results would not provide relevant information about this particular side effect.
Correct Answer is D
Explanation
A. Decrease in protein:
This choice is incorrect. Albumin is a protein found in the blood, and when a client is receiving an infusion of albumin, it is likely to increase, not decrease, the overall protein level in the bloodstream. Albumin infusions are often given to help increase plasma oncotic pressure and improve fluid retention in conditions like shock.
B. Oxygen saturation 96%:
This choice is incorrect. Oxygen saturation of 96% is within the normal range and reflects adequate oxygenation. It doesn't directly relate to the administration of albumin in shock.
C. PaCO2 30 mm Hg:
This choice is incorrect. The partial pressure of carbon dioxide (PaCO2) of 30 mm Hg reflects a respiratory value and doesn't directly relate to the administration of albumin or the management of shock. It's important for assessing acid-base balance, but it's not a specific finding related to the albumin infusion.
D. Increase in BP:
This is the correct choice. Albumin is a colloid solution that helps increase the oncotic pressure within blood vessels, which can contribute to an increase in blood volume. When blood volume increases, it can lead to an increase in blood pressure, which is a desired effect in the management of shock. Increasing blood pressure helps improve perfusion to vital organs and tissues, which is essential in shock situations.
