A client with chronic kidney disease receives a prescription for darbepoetin alfa 40 mcg subcutaneous every 7 days.

The darbepoetin alfa vial is labeled, "60 mcg/mL." How many mL should the nurse administer? round to the nearest tenth.

A.

0.7 mL.

B.

1.0 mL.

C.

1.3 mL.

D.

1.7 mL.

Answer and Explanation

The Correct Answer is A

Step 1 is to determine the amount of darbepoetin alfa in each mL of solution. The vial is labeled as “60 mcg/mL”, which means each mL contains 60 mcg of darbepoetin alfa.

Step 2 is to calculate the volume of the solution that contains 40 mcg of darbepoetin alfa. This can be done by dividing the prescribed dosage by the concentration of the solution. So, the volume is 40 mcg ÷ 60 mcg/mL = 0.67 mL.

However, since we need to round to the nearest tenth, the volume becomes 0.7 mL.

So, the correct answer is, after analysing all choices, the nurse should administer 0.7 mL of the darbepoetin alfa solution.

Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"D"}

Explanation

Choice A rationale:

A pH level of 7.35 to 7.45 and HCO3- level of 22 to 26 mEq/L indicate a resolution of ketoacidosis. The normal pH range for the body is 7.35 to 7.45, and a return to this range indicates that the body’s acid-base balance has been restored. The bicarbonate (HCO3-) level is a measure of the metabolic component of the body’s acid-base balance, and the normal range is 22 to 26 mEq/L. A return to this range indicates that the metabolic acidosis caused by the ketoacidosis has been resolved.

Choice B rationale:

A pH level of 7.25 to 7.35 and HCO3- level of 18 to 22 mEq/L would indicate that the client is still in a state of mild acidosis, as the pH is below the normal range and the bicarbonate level is also slightly low, indicating a metabolic acidosis.

Choice C rationale:

A pH level of 7.15 to 7.25 and HCO3- level of 14 to 18 mEq/L would indicate a moderate acidosis. Both the pH and bicarbonate levels are significantly below their normal ranges, indicating a significant disruption in the body’s acid-base balance.

Choice D rationale:

A pH level of 7.05 to 7.15 and HCO3- level of 10 to 14 mEq/L would indicate severe acidosis, which would be life-threatening if not corrected. Both the pH and bicarbonate levels are far below their normal ranges, indicating a severe disruption in the body’s acid-base balance. In conclusion, choice A is correct because it represents values within the normal ranges for both pH and bicarbonate, indicating a resolution of ketoacidosis.

Correct Answer is B

Explanation

Choice B rationale:

Explaining that the client will start to lose consciousness and the body systems will slow down is the best response. This is a common pattern in the dying process, and it provides the wife with a clear and compassionate explanation of what to expect as her husband's death approaches.

Choice A rationale:

Gathering information regarding how long it will take for the children to arrive is important but does not address the immediate need for information on the dying process.

Choice C rationale:

Offering to discuss the client's health status with each of the adult children is a good approach for involving them in their father's care but does not provide the immediate information the wife is seeking.

Choice D rationale:

Reassuring the spouse that the healthcare provider will notify when to call the children does not offer information about the dying process itself, which is what the wife is interested in understanding.
