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.
0.7 mL.
1.0 mL.
1.3 mL.
1.7 mL.
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 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.
Correct Answer is B
Explanation
Choice A rationale:
Tenderness is not considered a normal finding during percussion of the abdomen. Tenderness suggests an underlying issue or inflammation in the abdominal area, which requires further evaluation and investigation.
Choice B rationale:
Musical and drumlike sounds are considered normal findings during percussion of the abdomen. These sounds indicate the presence of air-filled structures like the stomach or intestines. Normal abdominal percussion sounds are tympanic, and they are characterized by a hollow, drum-like quality when the abdomen is tapped lightly. This finding suggests that there are no significant abnormalities in the abdominal area.
Choice C rationale:
Absent sounds during abdominal percussion are not considered normal and may indicate a potential problem. Absent sounds could be due to factors such as bowel obstruction or severe constipation, which require further assessment and intervention.
Choice D rationale:
Pain during abdominal percussion is not considered a normal finding. It indicates discomfort or tenderness in the abdominal area, which requires further evaluation to determine the underlying cause.
