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 ["A","C","D","E"]
Explanation
Choice A rationale:
Verapamil is a calcium channel blocker and is expected to decrease heart rate by inhibiting calcium influx into cardiac cells, particularly in the SA (sinoatrial) node, where it can slow down the heart's electrical impulses.
Choice B rationale:
Increased contractility is not an expected outcome of verapamil use. In fact, verapamil's main action is to decrease myocardial contractility, making it useful for treating conditions like angina and atrial fibrillation.
Choice C rationale:
Verapamil is known to dilate coronary arteries, which can improve blood flow to the heart muscle and relieve symptoms of angina.
Choice D rationale:
Reduced blood pressure is an expected outcome of verapamil use due to its vasodilatory effects on peripheral blood vessels. This can be beneficial in treating hypertension and angina.
Choice E rationale:
Relieved chest pain is an expected outcome of verapamil use, particularly in the case of variant angina (Prinzmetal's angina), as it helps to relax coronary arteries and reduce coronary artery spasm, which is a common cause of chest pain in this condition.
Correct Answer is B
Explanation
Choice A rationale:
The statement, "This medication will shorten the duration of my symptoms," is correct. Oseltamivir is an antiviral medication used to treat influenza, and it can reduce the duration of symptoms when taken early in the course of the illness.
Choice B rationale:
The statement, "This medication will prevent me from spreading the virus to others," is incorrect. While oseltamivir can help reduce the severity and duration of symptoms, it does not prevent the spread of the virus to others. Clients with influenza should still take precautions to avoid transmitting the virus to others.
Choice C rationale:
The statement, "This medication will work best if I start taking it within 48 hours of symptom onset," is correct. Oseltamivir is most effective when started within 48 hours of the onset of symptoms.
Choice D rationale:
The statement, "This medication may cause nausea and vomiting as side effects," is correct. Nausea and vomiting are potential side effects of oseltamivir, and clients should be informed about these possible adverse reactions.
