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 B

Explanation

A. The inhaler will be used before bed each night:
The timing of inhaler use depends on the type of medication (e.g., rescue vs. maintenance) and individual needs, not a fixed schedule like before bed. Proper use instructions usually specify whether it’s for acute symptoms or regular daily use.

B. Rinsing the mouth with water should be done after each use:
This is an important practice for inhaled corticosteroids to help prevent oral thrush and minimize side effects. It ensures that any residual medication is removed from the mouth.

C. Caffeinated beverages should be limited to two cups per day:
While caffeine may have interactions with certain medications, it is not specifically related to the use of inhalers. Therefore, this statement is less relevant to the immediate use of the inhaler.

D. To mask the taste of the medication, inhaler can be used during meals:
Using an inhaler during meals is not advised. It is important to use the inhaler as directed, typically separate from meals, to ensure proper inhalation and effectiveness of the medication.

A. Hematocrit 42% (0.42 volume fraction). B. Hemoglobin 13 g/dL (8.07 mmol/L). C. Positive guaiac of stool. D. Gastric pH 2.0.

Correct Answer is C

Explanation

A. Hematocrit 42% (0.42 volume fraction):
A hematocrit of 42% is within the normal reference range for males (42% to 52%). While it is important to monitor hematocrit levels, this finding alone does not indicate an immediate issue.

B. Hemoglobin 13 g/dL (8.07 mmol/L):
A hemoglobin level of 13 g/dL is slightly below the normal range for males (14 to 18 g/dL). However, it is not critically low and may not require immediate intervention without additional context or symptoms.

C. Positive guaiac of stool:
A positive guaiac test for stool indicates the presence of occult blood in the stool, which could suggest gastrointestinal bleeding. Given the client's history of heartburn, indigestion, and use of ibuprofen (a nonsteroidal anti-inflammatory drug that can cause gastrointestinal bleeding), this finding is concerning and should be reported immediately to the healthcare provider for further evaluation and management.

D. Gastric pH 2.0:
A gastric pH of 2.0 is within the normal range for gastric acid, as the normal pH of gastric acid typically ranges from 1.5 to 3.5. This finding is expected and does not indicate an immediate problem related to the client's symptoms.
