The nurse is caring for a client who is taking atorvastatin to assist in lowering his LDL cholesterol. Which lab value must be routinely done with this medication to prevent complications?
Platelet counts
Lung function test
Liver function test
Bun and Creatine levels
The Correct Answer is C
A) Platelet counts: Monitoring platelet counts is not necessary with atorvastatin therapy. While certain medications may affect platelet levels, atorvastatin primarily targets lipid levels and does not have a significant impact on platelet function.
B) Lung function test: Lung function tests are not relevant for atorvastatin use. These tests are typically utilized for assessing respiratory conditions and are not part of the routine monitoring for cholesterol-lowering medications.
C) Liver function test: Atorvastatin can affect liver function, so it is essential to monitor liver
enzymes (such as AST and ALT) regularly. Routine liver function tests help identify any potential hepatotoxicity early, allowing for timely intervention if liver function declines.
D) Bun and creatinine levels: While monitoring renal function can be important in some contexts, it is not a routine requirement specifically for atorvastatin. However, it may be necessary in certain patient populations or if there are concerns about kidney function, but liver function tests are the primary focus with this medication.

Correct Answer is D
Explanation
A) Pulse oximetry of 92%: While a pulse oximetry reading of 92% is slightly below normal, it is not a definitive reason to hold verapamil. This reading indicates mild hypoxemia, but it does not directly contraindicate the use of verapamil. Other factors should be considered before making a decision based solely on this value.
B) Pulse of 78: A pulse rate of 78 beats per minute is within the normal range for adults and does not warrant holding verapamil. This finding alone does not indicate any immediate concerns related to the administration of the medication.
C) Respiratory rate of 12: A respiratory rate of 12 breaths per minute is within the normal range for adults. This finding does not provide any indication that verapamil should be withheld. It is important to consider other clinical factors when assessing the appropriateness of medication administration.
D) History of myocardial infarction a week ago: Verapamil, a calcium channel blocker, can have significant effects on cardiac function. Administering it to a client who recently experienced a myocardial infarction (heart attack) could exacerbate cardiac issues and lead to complications. Therefore, it is crucial to hold the medication and consult with the healthcare provider before proceeding.
Correct Answer is C
Explanation
A) Beta Blockers: While beta blockers can be used to manage some side effects of various medications, they are not typically indicated for managing niacin-induced flushing. Their primary use is in cardiovascular conditions rather than specifically addressing flushing.
B) Calcium Channel Blockers: Calcium channel blockers are primarily used to treat hypertension and certain heart conditions. They do not specifically address the flushing associated with niacin and would not be the expected choice for this side effect.
C) NSAIDs: Nonsteroidal anti-inflammatory drugs (NSAIDs) can be effective in managing niacin-induced flushing. Administering an NSAID, such as ibuprofen, prior to taking niacin can help reduce the flushing response by inhibiting the prostaglandins that contribute to this side effect.
D) Fibric Acid Derivatives: These medications, such as gemfibrozil, are used to lower triglycerides and cholesterol levels, but they do not address the flushing side effect caused by niacin. Their mechanism of action is different and not focused on alleviating flushing symptoms.
