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
Explanation
When a client refuses to look at their mastectomy incision and refuses to talk about it, the best response by the practical nurse (PN) is to respect the client's autonomy and validate their feelings. Option a) acknowledges the client's discomfort and provides reassurance that it is okay for them to decline looking or talking about the incision at the moment. It also offers support by letting the client know that the incision will be available for examination when they feel ready to do so.
Let's evaluate the other options:
b) "Would you like me to call another nurse to be here while I show you the wound?"
This response assumes that the client needs someone else present to address their refusal to look at the incision. While having another nurse present may be helpful for some clients, it is not the appropriate first response. Respecting the client's autonomy and providing support should be the initial approach.
c) "Part of recovery is accepting your new body image, and you will need to look at your incision."
This response may come across as directive and insensitive. It implies that the client must look at their incision as part of their recovery process, disregarding their feelings and personal choices. It is important to respect the client's autonomy and allow them to navigate their own healing journey at their own pace.
d) "You will feel beter when you see that the incision is not as bad as you may think."
This response invalidates the client's feelings and assumes that their concerns about the incision are unfounded. It is essential to respect the client's emotions and validate their experience rather than dismissing or minimizing their concerns.
In summary, when a client refuses to look at their mastectomy incision and refuses to talk about it, the best response by the practical nurse (PN) is to acknowledge the client's discomfort, respect their autonomy, and provide reassurance that it is okay for them to decline looking or talking about the incision at that moment. The client's readiness to address the incision should be honored, and support should be offered when they are ready.
Correct Answer is D
Explanation
Step 1 is to convert the child’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.2 lbs. So, the child’s weight in kg is 55 lbs ÷ 2.2 = 25 kg (rounded to the nearest whole number for simplicity).
Step 2 is to calculate the total daily dosage. The prescription is for 150 mg/kg/day. So, the total daily dosage is 150 mg/kg/day × 25 kg = 3750 mg/day.
So, the correct answer is, after analysing all choices, the nurse should administer 3750 mg of cefotaxime each day.
