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 D

Explanation

A) Neutropenia:
Neutropenia, a low level of neutrophils (a type of white blood cell), is not a typical adverse effect associated with atenolol. Atenolol primarily affects cardiovascular function rather than hematologic parameters like neutrophil count.

B) Anemia:
Anemia, a decrease in red blood cells or hemoglobin levels, is not commonly associated with atenolol use. Beta-blockers do not typically affect red blood cell production or hemoglobin levels.

C) Hypokalemia:
Hypokalemia, or low potassium levels, can occur with some medications, but it is not a well-documented adverse effect of atenolol specifically. Atenolol may affect potassium levels indirectly through its effects on the cardiovascular system, but it is not a primary adverse effect.

D) Bradycardia:
Atenolol is a beta-blocker medication that primarily works by slowing the heart rate and reducing the force of heart contractions. Bradycardia, or a slow heart rate, is a known adverse effect of beta-blockers like atenolol. It occurs due to the medication's mechanism of action in blocking beta-adrenergic receptors, which can lead to decreased heart rate.

A. A client taking a potassium supplement twice a day B. A client taking aluminum hydroxide for gastric upset C. A client taking chlorpropamide for type 2 diabetes mellitus D. A client taking furosemide for chronic hypertension

Correct Answer is D

Explanation

A) A client taking a potassium supplement twice a day:
Taking potassium supplements can actually lower the risk of digoxin toxicity because hypokalemia (low potassium levels) increases the risk of digoxin toxicity. Potassium supplements help maintain adequate potassium levels, which is beneficial for clients taking digoxin.

B) A client taking aluminum hydroxide for gastric upset:
Aluminum hydroxide can bind to digoxin in the gastrointestinal tract, reducing its absorption. This interaction can decrease the effectiveness of digoxin rather than increase the risk of toxicity.

C) A client taking chlorpropamide for type 2 diabetes mellitus:
Chlorpropamide does not interact significantly with digoxin or affect electrolyte levels in a way that would increase the risk of digoxin toxicity.

D) A client taking furosemide for chronic hypertension:
Furosemide, a loop diuretic, can cause hypokalemia and hypomagnesemia, which are risk factors for digoxin toxicity. Low potassium levels enhance the toxicity of digoxin by increasing its binding to cardiac tissue receptors, leading to enhanced cardiac effects.
