The nurse is caring for a client with atrial fibrillation who receives a prescription for warfarin. The international normalized ratio (INR) is 2.8. Which action should the nurse take?

Give the next scheduled dose.

Obtain another blood sample.

Monitor for signs of bleeding.

Notify the healthcare provider.

Answer and Explanation

The Correct Answer is D

Choice A reason: Giving the next scheduled dose without further assessment is not advisable. An INR of 2.8 is within the therapeutic range for many conditions treated with warfarin, but it is important to ensure that the INR is stable and not trending higher, which could increase the risk of bleeding.

Choice B reason: Obtaining another blood sample might be necessary if there is suspicion of an error or if the INR is unexpectedly high or low. However, in this scenario, the INR is within the therapeutic range, so this action is not immediately necessary.

Choice C reason: Monitoring for signs of bleeding is always important for clients on warfarin, but it does not address the immediate need to communicate with the healthcare provider about the current INR level and any potential adjustments to the medication.

Choice D reason: Notifying the healthcare provider is the most appropriate action. The healthcare provider needs to be aware of the current INR level to make any necessary adjustments to the warfarin dosage and to provide further instructions on monitoring and follow-up.

Correct Answer is D

Explanation

Choice A reason: A complete blood count (CBC) is not typically required before starting statin therapy. While a CBC can provide valuable information about a patient’s overall health, it does not specifically relate to the potential side effects or necessary monitoring for statin use. Statins primarily affect the liver, so monitoring liver function is more critical.

Choice B reason: Serum electrolytes are important for assessing overall metabolic and kidney function, but they are not directly related to the initiation of statin therapy. Statins do not typically affect electrolyte levels, so this test is not necessary before starting the medication.

Choice C reason: Capillary blood glucose levels are important for monitoring diabetes and blood sugar control. While statins can have an impact on blood glucose levels, this is not the primary concern when initiating therapy. Monitoring liver function is more directly related to the potential side effects of statins.

Choice D reason: Serum liver enzymes are crucial to review before starting statin therapy. Statins can cause liver enzyme elevations, indicating liver damage or dysfunction. Therefore, baseline liver enzyme levels should be obtained to monitor for any potential hepatotoxicity during treatment.

A. Eliminates urinary bacteria. B. Use the medication after voiding after sexual intercourse. C. Calms spasms in the urinary tract. D. Provides an analgesic effect for irritated bladder mucosa.

Correct Answer is D

Explanation

Choice A reason:

Phenazopyridine does not eliminate urinary bacteria. It is not an antibiotic and does not have antibacterial properties. Instead, it is used to relieve symptoms such as pain, burning, and discomfort caused by irritation of the urinary tract. Therefore, this choice is incorrect.

Choice B reason:

Using phenazopyridine after voiding or after sexual intercourse is not a standard recommendation. This medication is typically taken after meals to reduce stomach upset. It is not specifically indicated for use after sexual intercourse, and this choice does not align with the typical usage instructions for phenazopyridine.

Choice C reason:

Phenazopyridine does not calm spasms in the urinary tract. Its primary function is to provide symptomatic relief from pain, burning, and discomfort in the urinary tract. It does not have antispasmodic properties, so this choice is also incorrect.

Choice D reason:

Phenazopyridine provides an analgesic effect for irritated bladder mucosa. It works by numbing the lining of the urinary tract, which helps to alleviate pain and discomfort associated with conditions like cystitis. This is the correct therapeutic effect of the medication.
