The nurse evaluates a client's response to the prescribed atorvastatin. Which finding indicates an expected outcome?
Total cholesterol 198 mg/dL
Low density lipoprotein (LDL) 90 mg/dL
Serum albumin 6 g/L
Alanine aminotransferase (ALT) 25 units/L
The Correct Answer is B
A) Total cholesterol 198 mg/dL: While this value is within normal limits, it does not specifically indicate the effectiveness of atorvastatin treatment, which primarily aims to lower LDL levels. An optimal outcome would focus more on the LDL reduction rather than total cholesterol alone.
B) Low density lipoprotein (LDL) 90 mg/dL: This finding indicates an expected outcome of atorvastatin therapy. Atorvastatin is effective at lowering LDL cholesterol, which is a key target in managing hyperlipidemia and reducing the risk of cardiovascular events. An LDL level below 100 mg/dL is generally considered optimal.
C) Serum albumin 6 g/L: This value is low and indicates potential malnutrition or liver dysfunction, which are not expected outcomes for a client on atorvastatin. A normal serum albumin level typically ranges from 3.5 to 5.0 g/dL, so this finding is concerning.
D) Alanine aminotransferase (ALT) 25 units/L: While this ALT level is within the normal range, it does not directly reflect the primary goal of atorvastatin therapy, which is to lower LDL cholesterol. Monitoring liver enzymes is important, but the expected outcome would be more clearly indicated by improved lipid profiles, particularly LDL levels.

Correct Answer is C
Explanation
A. 2 inches 21 gauge: This option is too long and too large in gauge for subcutaneous administration. Typically, a longer needle is not necessary for subcutaneous injections, especially for standard adult adipose tissue.
B. 1 1/2 inch 27 gauge: While this gauge is acceptable, the length is still longer than typically required for subcutaneous injections. A 1 1/2 inch needle is more suited for intramuscular injections.
C. 5/8 inch 25 gauge: This is the most appropriate choice for a subcutaneous injection. A 5/8 inch needle is typically adequate for subcutaneous tissue in adults, and a 25 gauge needle provides a suitable size for comfort while allowing the medication to be administered effectively.
D. 1/4 inch 19 gauge: This option is not suitable for subcutaneous injections. A 1/4 inch length is too short for effective penetration into subcutaneous tissue, and a 19 gauge needle is larger than necessary, which could increase discomfort.
Correct Answer is ["480"]
Explanation
To calculate the infusion rate, you need to determine the total volume to be infused and the time over which it will be infused.
Total volume to be infused = 200 mL
Time for infusion = 25 minutes
Infusion rate = Total volume / Time Infusion rate = 200 mL / 25 minutes = 8 mL/min
To convert this to mL/hour (since infusion pumps are typically set in mL/hour): Infusion rate = 8 mL/min × 60 minutes/hour = 480 mL/hour
