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.

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 B

Explanation

The correct answer is B

Choice A reason: Vasopressin is not typically associated with decreasing GI cramping and nausea. It is used to treat diabetes insipidus and to reduce stomach bloat for some procedures and after some surgeries.

Choice B reason: Vasopressin can cause chest pain or pressure, and fast, slow, or abnormal heartbeat, which are indicative of dysrhythmia. These are known side effects of vasopressin and should be monitored during IV infusion.

Choice C reason: Vasopressin causes vasoconstriction, not vasodilation. It tightens small blood vessels, which is the opposite of vasodilation.

Choice D reason: While vasopressin can cause bradycardia (slow heart rate), hypotension is not a common effect as it is used to treat low blood pressure. Tachycardia (fast heart rate) is not a typical side effect of vasopressin.

A. Administer a prescribed PRN stool softener B. Determine the client's usual bowel patern C. Encourage the client to ambulate more frequently D. Recommend increasing high-fiber foods daily

Correct Answer is B

Explanation

A bowel patern is the frequency, consistency, and appearance of a person's bowel movements. A normal bowel patern is what's normal for each person, and it can vary depending on factors such as diet, age, physical activity, and health conditions.
A focused gastrointestinal system assessment includes collecting subjective data about the patient's history of gastrointestinal disease, signs and symptoms of gastrointestinal problems, diet and nutrition, and bowel patern. It also includes inspecting and auscultating the abdomen for any abnormalities³.
When a client reports having a bowel movement three days ago, the first action that the practical nurse should implement is to determine the client's usual bowel patern. This will help to evaluate if the client is experiencing constipation or if this is their normal frequency. It will also help to identify any changes or risk factors that may aﬀect the client's bowel function.

Therefore, option B is the correct answer, while options A, C, and D are incorrect.

Option A is incorrect because administering a stool softener without assessing the client's bowel patern may not be appropriate or eﬀective.

Option C is incorrect because encouraging ambulation may help to stimulate bowel activity, but it is not the first action to take.

Option D is incorrect because recommending dietary changes may be helpful for preventing or treating constipation, but it is not the first action to take.
