A nurse is preparing to administer potassium chloride 20 mEq. The amount available is potassium chloride liquid 40 mEq/15 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["7.5"]

We can calculate the volume of potassium chloride solution to administer using the following steps:

Identify the prescribed dose: The nurse needs to administer 20 mEq of potassium chloride.

Identify the concentration of available solution: The potassium chloride liquid is available in a concentration of 40 mEq/15 mL. This means there are 40 milliequivalents (mEq) of potassium chloride in every 15 milliliters (mL) of the solution.

Set up a proportion to find the volume needed:

Desired dose (mEq) : Volume to administer (mL) = Concentration (mEq/mL)

Plug in the values:

20 mEq : Volume to administer (mL) = 40 mEq/15 mL

Solve for the volume:

To isolate the volume (mL), multiply both sides of the proportion by the volume unit (mL) and divide by the dose (mEq).

Volume to administer (mL) = (20 mEq) x (mL) / (40 mEq/15 mL)

We can simplify the calculation before dividing:

Volume to administer (mL) = (20 mEq x 15 mL) / 40 mEq

Volume to administer (mL) = 300 mL / 40 mEq

Volume to administer (mL) = 7.5 mL (round to one decimal place)

Therefore, the nurse should administer 7.5 mL of the potassium chloride solution.

Correct Answer is B

Explanation

A) Serum calcium 10.5 mg/dL:
A serum calcium level of 10.5 mg/dL is within the normal range (8.5-10.5 mg/dL). Spironolactone does not typically affect calcium levels significantly.

B) Serum potassium 5.2 mEq/L:
An elevated serum potassium level (hyperkalemia) is a known adverse effect of spironolactone. Spironolactone is a potassium-sparing diuretic that inhibits aldosterone, leading to decreased potassium excretion and potential hyperkalemia, especially in clients with impaired renal function.

C) Serum chloride 99 mEq/L:
A serum chloride level of 99 mEq/L is within the normal range (96-106 mEq/L). Spironolactone does not typically affect chloride levels significantly.

D) Serum sodium 140 mEq/L:
A serum sodium level of 140 mEq/L is within the normal range (135-145 mEq/L). Spironolactone does not typically affect sodium levels significantly.

A. Notify the nurse manager. B. Complete an incident report. C. Give the client 15 to 20 g of carbohydrate. D. Check the client's blood glucose level

Correct Answer is D

Explanation

A) Notify the nurse manager:
While it's important to communicate the error to the nurse manager and appropriate supervisors, the immediate priority is to address the client's current condition and ensure their safety.

B) Complete an incident report:
Filling out an incident report is necessary to document the error and ensure proper follow-up and investigation. However, the client's immediate well-being takes precedence.

C) Give the client 15 to 20 g of carbohydrate:
Administering carbohydrates may be necessary if the client is hypoglycemic, but checking the blood glucose level first is essential to confirm the current status and determine the appropriate intervention.

D) Check the client's blood glucose level:
This is the priority action because it allows the nurse to assess the client's current blood glucose level and determine if corrective action, such as administering carbohydrates or further insulin adjustments, is needed to address any potential hypoglycemia resulting from the incorrect insulin dose.
