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 D

Explanation

A. Apply warm compresses to legs:
While leg cramps can be uncomfortable, addressing them with warm compresses does not address the potential underlying issues related to the client's symptoms, especially considering the possibility of more severe conditions.

B. Monitor intake and output:
Monitoring intake and output is important in managing fluid balance, especially with diuretics like furosemide. However, this action does not directly address the immediate concerns raised by symptoms like palpitations and a cough.

C. Raise the head of the bed:
Raising the head of the bed can be helpful if the client is experiencing shortness of breath or orthopnea. However, it does not address the need to evaluate cardiac function, which is crucial given the presence of palpitations and other symptoms.

D. Place on cardiac monitoring:
The client's symptoms—palpitations, cough, fatigue—could indicate significant electrolyte imbalances or cardiac issues, which are common with furosemide use. Cardiac monitoring is the most appropriate initial action to quickly identify and address any cardiac complications.

A. Wear padding to protect from bruising if a fall occurs. B. Take measures to avoid dehydration and over-heating. C. Avoid crowds to help prevent acquiring infections. D. Keep skin and eyes covered to protect from sun injury.

Correct Answer is B

Explanation

A. Wear padding to protect from bruising if a fall occurs:
While safety precautions are important for any physical activity, the specific concern with oxybutynin is not related to a higher risk of falls or bruising. The primary issue is managing side effects that might affect hydration and body temperature.

B. Take measures to avoid dehydration and over-heating:
Oxybutynin can cause dry mouth and decreased sweating, which can increase the risk of dehydration and overheating, especially during intense physical activities like running. Emphasizing hydration and measures to avoid overheating is crucial to prevent complications.

C. Avoid crowds to help prevent acquiring infections:
Oxybutynin does not typically affect the immune system or increase the risk of infections. The client’s concern should focus on managing side effects related to exercise and hydration, rather than avoiding crowds.

D. Keep skin and eyes covered to protect from sun injury:
Oxybutynin does not have a direct effect on sun sensitivity or increase the risk of sunburn. While sun protection is generally important for outdoor activities, it is not a specific concern related to the use of oxybutynin.
