The nurse is reviewing the client's laboratory values. Which serum laboratory value indicates to the nurse that a prescription for atorvastatin is having the desired effect for a client at risk for coronary artery disease?

High density lipoprotein (HDL)

Low density lipoprotein (LDL).

Creatine phosphokinase (CK).

Prothrombin time (PT).

Answer and Explanation

The Correct Answer is B

A. High density lipoprotein (HDL):
HDL levels are important for cardiovascular health as higher levels are associated with a lower risk of coronary artery disease. However, atorvastatin primarily targets LDL levels. While increasing HDL is beneficial, it is not the primary measure of atorvastatin's effectiveness.

B. Low density lipoprotein (LDL):
Atorvastatin is a statin medication used to lower LDL cholesterol levels, which is a major risk factor for coronary artery disease. A decrease in LDL levels indicates that the medication is having its desired effect, reducing the risk of cardiovascular events.

C. Creatine phosphokinase (CK):
CK levels are monitored to assess muscle damage or side effects related to statin use, such as rhabdomyolysis. While important for safety monitoring, changes in CK levels do not directly reflect the effectiveness of atorvastatin in managing cholesterol levels.

D. Prothrombin time (PT):
PT is used to evaluate blood clotting ability and is not directly related to the effectiveness of atorvastatin. It is more relevant for monitoring anticoagulant therapy rather than statin therapy for cholesterol management.

Correct Answer is ["200"]

Explanation

Calculations:

Total volume of the IV bag = 200 mL

Infusion time = 1 hour

To calculate the infusion rate in mL/hr, we use the formula:

Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hours)

Infusion rate (mL/hr) = 200 mL / 1 hour = 200 mL/hr

Therefore, the nurse should program the infusion pump to deliver 200 mL/hr.

Correct Answer is ["37.5"]

Explanation

Convert grams to milligrams: 4 grams = 4000 mg

Determine the concentration of magnesium sulfate in the solution: 4000 mg / 500 mL = 8 mg/mL

Calculate the volume needed to deliver 300 mg/hour:

300 mg/hour ÷ 8 mg/mL = 37.5 mL/hour

Therefore, the nurse should set the infusion pump to deliver 37.5 mL/hour.
