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 B
Explanation
Choice A rationale:
CP being one of the most common permanent physical disabilities in children is a general statement but does not directly address the mother's question about the progression of her child's impaired movements. It does not provide an explanation for the potential course of CP.
Choice B rationale:
Brain damage with CP is not progressive but does have a variable course. This response provides the best explanation to the mother's question. CP is a static neurological condition, which means that the initial brain injury that led to CP does not worsen over time. However, the functional abilities and impairments of a child with CP can vary widely and may change as the child grows and develops. Some children may improve with therapy and interventions, while others may have relatively stable impairments.
Choice C rationale:
Severe motor dysfunction determines the extent of successful habilitation is not entirely accurate. While the severity of motor dysfunction does play a role in the challenges a child with CP may face, it does not solely determine the extent of successful habilitation. Many factors, including early intervention, therapy, and individualized care, can influence a child's progress and potential for improvement.
Choice D rationale:
Continued development of the brain lesion determines the child's outcome is not an accurate statement. CP is primarily caused by non-pro
Correct Answer is A
Explanation
Choice A rationale:
Protamine sulfate is an antidote for heparin overdose and should be administered slowly intravenously to avoid rapid hemodynamic changes and potential adverse reactions.Administering it within 30 minutes ensures timely reversal of heparin’s anticoagulant effects.
Choice B rationale:
Administering protamine sulfate rapidly intramuscularly is incorrect because intramuscular administration is not recommended due to the risk of hematoma formation and slower absorption compared to intravenous administration.
Choice C rationale:
While slow intravenous administration is correct, the timing of 60 minutes is less effective compared to 30 minutes for reversing heparin’s effects promptly.
Choice D rationale:
Rapid intramuscular administration is incorrect for the same reasons as Choice B.Rapid administration can cause adverse reactions, and intramuscular administration is not the preferred route.
