An increase in which serum lab value indicates to the nurse that a prescription for atorvastatin is having the desired effect for a client at risk for coronary artery disease?

Low-density lipoprotein (LDL)

Prothrombin time (PT).

Creatine phosphokinase (CK)

High-density lipoprotein (HDL).

Answer and Explanation

The Correct Answer is D

A. Low-density lipoprotein (LDL): Atorvastatin's primary effect is to decrease LDL cholesterol levels. A decrease in LDL levels would indicate the medication is working as intended, not an increase.
B. Prothrombin time (PT): PT is a measure of blood clotting, which is not directly affected by atorvastatin. This value is more relevant for monitoring anticoagulant therapy.

C. Creatine phosphokinase (CK): CK levels can be used to monitor for muscle damage or side effects related to statin use. An increase in CK levels would suggest muscle damage, not the effectiveness of the statin.
D. High-density lipoprotein (HDL): Atorvastatin is a statin medication used to lower cholesterol levels, particularly low-density lipoprotein (LDL) cholesterol, which is a key target in reducing the risk of coronary artery disease (CAD). While the primary goal of atorvastatin is to lower LDL cholesterol, an increase in HDL cholesterol (often termed "good" cholesterol) is also desirable as it can help reduce the risk of CAD. Therefore, an increase in HDL is a positive indicator that the medication is having a beneficial effect.

Correct Answer is B

Explanation

A. Obtain a platelet count weekly: Regular monitoring of platelet counts is important for clients on methotrexate due to the risk of bone marrow suppression and potential thrombocytopenia. This instruction is appropriate and necessary.
B. Take the medication during pregnancy: Methotrexate is contraindicated during pregnancy due to its teratogenic effects and potential to cause fetal harm. It is crucial for clients to avoid using methotrexate while pregnant or planning to become pregnant.
C. Use folic acid to protect the liver: While folic acid is often used to help reduce the side effects of methotrexate, particularly its gastrointestinal effects and potential for liver toxicity, it is not used to "protect the liver" per se. The correct approach is to use folic acid as directed by a healthcare provider, often to mitigate some of the side effects of methotrexate.
D. Store the medication at room temperature: Methotrexate should be stored according to the manufacturer's instructions, which usually involve keeping it at room temperature. This information is correct and does not require additional instruction.

A. Reduce caffeine and acidic intake. B. Double the dose if a dose is missed. C. Avoid taking on an empty stomach. D. Consume 2 liters of water daily.

Correct Answer is B

Explanation

A. Reduce caffeine and acidic intake: This is appropriate advice as caffeine and acidic foods can potentially affect uric acid levels and might exacerbate gout symptoms.
B. Double the dose if a dose is missed: This is incorrect and requires additional instruction. Allopurinol should not be doubled if a dose is missed. Instead, the missed dose should be taken as soon as possible unless it is almost time for the next dose. Doubling the dose could lead to increased risk of side effects or adverse reactions.
C. Avoid taking on an empty stomach: This is generally good advice, although allopurinol can be taken with or without food. Taking it with food might help reduce potential gastrointestinal discomfort.
D. Consume 2 liters of water daily: This is recommended to help prevent the formation of uric acid crystals and to ensure adequate hydration, which is beneficial while on allopurinol.
