A healthcare provider orders nitroprusside (100 mg/1 mL) 3 mcg/kg/minute for a patient weighing 154 lb. What rate (mL/hr) should the nurse program into the IV pump?
126 mL/hr
1.26 mL/hr
1260 mL/hr
12.6 mL/hr
The Correct Answer is B
First, we need to convert the patient's weight from pounds to kilograms using the conversion factor 1 kg =
2.2 lb:
154 lb / 2.2 lb/kg = 70 kg
Next, we need to calculate the dose of nitroprusside in mcg/min using the formula Dose = Weight × Dosage:
Dose = 70 kg × 3 mcg/kg/min = 210 mcg/min
Then, we need to convert the dose of nitroprusside from mcg/min to mg/hr using the conversion factor 1 mg = 1000 mcg:
210 mcg/min × 1 mg/1000 mcg × 60 min/hr = 12.6 mg/hr
Finally, we need to calculate the rate of nitroprusside in mL/hr using the formula Rate = Dose/Concentration:
Rate = 12.6 mg/hr / 100 mg/mL = 0.126 mL/hr
To round to the nearest hundredth, we get 0.13 mL/hr, which is approximately equal to 1.26 mL/hr.
Therefore, the nurse should program the IV pump to deliver nitroprusside at a rate of 1.26 mL/hr.

Correct Answer is D
Explanation
This statement is correct because the abdomen has a large surface area and a good blood supply, which allows for a consistent and predictable absorption of insulin. Insulin is a hormone that regulates blood glucose levels and needs to be delivered in precise doses to avoid complications such as hypoglycemia (low blood glucose) or hyperglycemia (high blood glucose).
The abdomen is also easy to access and has less variation in fat thickness, which reduces the risk of injecting into the muscle or the skin instead of the subcutaneous tissue. The subcutaneous tissue is the layer of fat and connective tissue below the skin and above the muscle, where insulin injections are given.
The other statements are not correct because they do not explain why the abdomen is the preferred site for subcutaneous insulin injections or they contain false information.
a.It is the least painful location for this injection. This statement is false because pain is subjective and depends on many factors, such as the type and size of the needle, the technique and speed of injection, the temperature and viscosity of the insulin, and the individual's pain tolerance and sensitivity. The abdomen may not be the least painful location for everyone, and some people may prefer other sites, such as the arms, thighs, or butocks.
b.There are fewer insulin side effects when given in this site. This statement is false because insulin side effects are not related to the site of injection, but to the dose, type, and timing of insulin, as well as the individual's response to insulin and other factors, such as diet, exercise, stress, illness, and medications. Insulin side effects may include hypoglycemia, weight gain, allergic reactions, lipodystrophy (changes in fat tissue), or edema (swelling).
c.It causes less bruising at the site. This statement is false because bruising is caused by bleeding under the skin due to damage to blood vessels during injection. Bruising can occur at any site of injection and depends on many factors, such as the type and size of the needle, the technique and speed of injection, the pressure applied after injection, the individual's clotting ability and blood thinning medications, and the presence of any underlying conditions that affect blood vessels or circulation.
Correct Answer is A
Explanation
To find the number of capsules of amoxicillin required for 5 days, you need to calculate the following:
- The total dose of amoxicillin in milligrams (mg) for 5 days using the formula: Total dose (mg) = Prescribed dose (mg) x Frequency (times/day) x Duration (days)
- The number of capsules of amoxicillin using the formula: Number of capsules = Total dose (mg) / Strength per capsule (mg)
First, use the formula for total dose to find the amount of amoxicillin in milligrams for 5 days:
Total dose (mg) = Prescribed dose (mg) x Frequency (times/day) x Duration (days)
Since the prescribed dose is 250 mg, the frequency is 3 times per day, and the duration is 5 days, plug in these values into the formula:
Total dose (mg) = 250 mg x 3 times/day x 5 days
Simplify and solve for the total dose:
Total dose (mg) = 3750 mg
Next, use the formula for number of capsules to find how many capsules of amoxicillin are needed:
Number of capsules = Total dose (mg) / Strength per capsule (mg)
Since the total dose is 3750 mg and the strength per capsule is 250 mg, plug in these values into the formula:
Number of capsules = 3750 mg / 250 mg
Simplify and solve for the number of capsules:
Number of capsules = 15
Therefore, the client needs **15 capsules** of amoxicillin for 5 days.
