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) "I take my alendronate at the same day every week with an 8-ounce glass of milk":
Taking alendronate with a full glass of plain water, not milk or any other beverage, is recommended to optimize absorption and minimize the risk of esophageal irritation. Using milk may interfere with the absorption of the medication.

B) "I sit up and read the morning paper after taking my alendronate,":
While it's important to remain upright (sitting or standing) for at least 30 minutes after taking alendronate to prevent esophageal irritation and optimize absorption, reading the morning paper doesn't necessarily ensure the client remains in an upright position. This statement indicates a need for further instruction regarding the importance of post-dose positioning.

C) "I will need to have a bone density test occasionally while taking this medication":
Monitoring bone density periodically is recommended while on alendronate to assess treatment effectiveness and bone health status. This statement shows understanding of the need for ongoing monitoring and does not require further instruction.

D) "I take my other pills at least 30 min after my alendronate,":
Taking other medications at least 30 minutes after alendronate helps to avoid interactions that may reduce its effectiveness. This statement demonstrates correct timing and understanding of medication administration instructions.

A. Regular B. Glargine C. NPH D. Detemir

Correct Answer is A

Explanation

A) Regular insulin:
Regular insulin is a short-acting insulin that acts quickly to lower blood glucose levels. It is suitable for managing diabetic ketoacidosis (DKA), which presents with symptoms such as confusion, flushed skin, and a fruity or acetone odor on the breath. Regular insulin helps to reduce ketone production and normalize blood glucose levels rapidly.

B) Glargine:
Glargine is a long-acting insulin that provides basal insulin coverage over an extended period. It is not typically used for the acute management of diabetic ketoacidosis due to its slow onset and prolonged duration of action.

C) NPH (Neutral Protamine Hagedorn):
NPH insulin is an intermediate-acting insulin that has a slower onset and duration compared to regular insulin. It is not the first choice for treating diabetic ketoacidosis due to its slower action.

D) Detemir:
Detemir is a long-acting insulin analogue that provides basal insulin coverage. Similar to glargine, it is not ideal for the acute treatment of diabetic ketoacidosis due to its slower onset and extended duration of action.
