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 ["A","B","C"]
Explanation
Choice A rationale:
Ibuprofen 400 mg every 4 to 6 hours as needed for temperature greater than 100.5 °F (38 °C). This order is questionable because ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can potentially increase blood pressure, which could be harmful to a patient with hypertension. Furthermore, NSAIDs can mask the symptoms of infection, which could delay the diagnosis and treatment of serious infections.
Choice B rationale:
Enalapril 10 mg every morning. This order is questionable because enalapril is an angiotensin-converting enzyme (ACE) inhibitor used to treat hypertension. However, ACE inhibitors can cause a dry cough, which could exacerbate the patient’s existing cough due to pneumonia. Additionally, ACE inhibitors can potentially cause hyperkalemia (high potassium levels), so it’s important to monitor the patient’s electrolyte levels.
Choice C rationale:
Supplemental oxygen 10 L/min via nasal cannula. This order is questionable because a high flow rate of oxygen can potentially cause oxygen toxicity or hyperoxia, which can lead to cellular damage. The typical flow rate for a nasal cannula is between 1-6 L/min. A flow rate of 10 L/min may be too high for this patient, especially without a specified target SpO2 range.
Choice D rationale:
Continuous pulse oximetry. This order is appropriate because it allows for continuous monitoring of the patient’s oxygen saturation levels, which is crucial in a patient with pneumonia and shortness of breath.
Choice E rationale:
Send blood for a complete blood count, electrolytes, blood cultures, and procalcitonin. This order is appropriate because these tests can help monitor the patient’s overall health status and response to treatment.
Choice F rationale:
Admit to the medical floor. This order is appropriate because the patient requires hospitalization for treatment and monitoring due to his pneumonia.
Choice G rationale:
Vital signs every 4 hours. This order is appropriate because it allows for regular monitoring of the patient’s vital signs, which can help detect any changes in his condition.
Choice H rationale:
Chest x-ray now. This order is appropriate because a chest x-ray can help confirm the diagnosis of pneumonia and assess its severity.
Choice I rationale:
Sputum culture and sensitivity. This order is appropriate because it can help identify the specific organism causing the pneumonia and determine its antibiotic sensitivity, which can guide antibiotic therapy.
Choice J rationale:
Levofloxacin 500 mg intravenously every 24 hours. This order is appropriate because levofloxacin is a broad-spectrum antibiotic commonly used to treat pneumonia.
Correct Answer is D
Explanation
Choice A rationale:
Instill 3 mL of normal saline before suctioning. This choice is not appropriate for suctioning excessive drooling in a client with ALS. Instilling normal saline would introduce additional fluid into the oral cavity, potentially worsening the problem by increasing the amount of secretions. The goal of suctioning is to remove excess saliva and maintain a clear airway.
Choice B rationale:
Instruct the client to cough as the suction tip is removed. Instructing the client to cough during suctioning is not a recommended practice. It may cause discomfort and can lead to an increased risk of aspiration as the client might inhale while coughing during the procedure.
Choice C rationale:
Apply a water-soluble lubricant to the catheter. Applying a water-soluble lubricant to the suction catheter is a common practice to facilitate the passage of the catheter and minimize irritation to the client's oral tissues. While it is a helpful step, it is not the primary action that should be taken to ensure the safety of the procedure.
Choice D rationale:
Wear protective goggles while performing the procedure. This is the correct choice. When suctioning a client's oral cavity, especially when dealing with excessive drooling or secretions, it is essential for the nurse to wear protective goggles. These goggles protect the nurse's eyes from potential exposure to the client's bodily fluids, reducing the risk of infection transmission.
