A client who weighs 176 pounds receives a prescription for norepinephrine 2 mcg/min intravenously (IV). The IV bag is labeled, "Norepinephrine 4 mg in dextrose 5% in water (D;W) 1,000 mL." How many mL/hour should the nurse program the infusion pump? (Enter numerical value only.).
The Correct Answer is ["30"]
The correct answer is 30 mL/hour.
Step 1 is to calculate the total amount of norepinephrine in the IV bag: 4 mg norepinephrine ÷ 1000 mL = 0.004 mg/mL
Step 2 is to convert the patient's weight from pounds to kilograms: 176 pounds ÷ 2.2 = 80 kilograms
Step 3 is to calculate the total amount of norepinephrine the patient will receive per minute: 2 mcg/min × 60 min = 120 mcg/min
Step 4 is to convert micrograms (mcg) to milligrams (mg): 120 mcg ÷ 1000 = 0.12 mg
Step 5 is to calculate the total volume of norepinephrine needed per hour: 0.12 mg ÷ 0.004 mg/mL = 30 mL/hour
Therefore, the nurse should program the infusion pump to deliver 30 mL/hour.

Correct Answer is D
Explanation
Choice A rationale:
Systemic autoimmune vasculopathy is not a typical underlying disease pathology associated with a waddling gait and frequent falls in a 5-year-old child. This choice is not relevant to the symptoms described.
Choice B rationale:
Autonomic neuropathy may manifest with a variety of symptoms, including autonomic dysregulation, but it is not a common underlying pathology leading to a waddling gait and frequent falls in a child. This choice is not relevant to the symptoms described.
Choice C rationale:
Impaired neuron function can result in various neurological symptoms, but it does not specifically explain the waddling gait and frequent falls in a 5-year-old child. This choice is not relevant to the symptoms described.
Choice D rationale:
Muscle fiber degeneration is the most appropriate explanation for the symptoms of a waddling gait and frequent falls in a 5-year-old child. These symptoms are indicative of a neuromuscular disorder known as Duchenne muscular dystrophy (DMD), which involves progressive muscle weakness and degeneration. DMD is characterized by the loss of muscle fibers and is a common cause of a waddling gait and falls in affected children. Therefore, choice D is the correct answer based on the understanding of the underlying disease pathology.
Correct Answer is B
Explanation
Choice A rationale:
Increasing the supplemental oxygen to 15 L/min via nasal cannula may seem like a logical step given the client’s low oxygen saturation. However, it’s important to note that oxygen therapy should be titrated carefully. Too much oxygen can lead to oxygen toxicity, which can cause cellular damage and worsen the client’s condition. Therefore, this is not the priority action.
Choice B rationale:
Notifying the health care provider of the client’s condition is the priority action. The client’s oxygen saturation is 88% on room air, which is below the normal range of 95% to 100%. This indicates that the client is not getting enough oxygen, which can lead to hypoxia and other serious complications. The health care provider needs to be informed immediately so that appropriate interventions can be initiated.
Choice C rationale:
Administering ibuprofen as ordered for fever is important, but it’s not the priority in this situation. While fever can indicate an infection, which could be contributing to the client’s low oxygen saturation, addressing the immediate issue of hypoxia is more critical.
Choice D rationale:
Obtaining a sputum culture from the client could provide valuable information about the type of bacteria causing the pneumonia and guide antibiotic therapy. However, this is not an immediate priority compared to addressing the client’s low oxygen saturation. In summary, while all these actions are important in caring for a client with pneumonia, the nurse must prioritize interventions based on their urgency and potential impact on the client’s health status. In this case, notifying the health care provider of the client’s condition is the most critical action.
