A nurse is preparing to administer vancomycin IV to an adult client. The client asks the nurse if the medication can be given 2 hr earlier. Which of the following statements should the nurse make?

This is because humidification can help moisten the oral mucosa and reduce the discomfort of xerostomia. Xerostomia is a condition of dry mouth caused by reduced or absent saliva flow, which can occur after radiation therapy to the head and neck area.
Choice A is wrong because rinsing the mouth with an alcohol-based mouthwash can irritate the oral tissues and worsen xerostomia. Alcohol can also dehydrate the mouth and reduce saliva production.
Choice B is wrong because esophageal speech is a method of voice restoration after laryngectomy, not a treatment for xerostomia.
Esophageal speech involves swallowing air into the esophagus and releasing it to create sound.
It has nothing to do with saliva flow or dry mouth.
Choice C is wrong because saltine crackers are dry and hard to swallow without adequate saliva.
They can also scratch the oral mucosa and cause pain or bleeding. Offering the client saltine crackers between meals can aggravate xerostomia and increase the risk of choking.
Normal ranges for saliva flow vary depending on the method of measurement, but generally, a stimulated saliva flow rate of less than 0.7 mL/min or an unstimulated saliva flow rate of less than 0.1 mL/min is considered indicative of xerostomia.

The correct answer is choice D: A client who is taking warfarin and has an INR of 1.8.

Choice A rationale:

A Mantoux test with an induration after 48 hours can be a normal reaction, especially if the induration is within the expected size range for a positive result, depending on the individual’s risk factors and history. It does not necessarily require follow-up care unless the induration is significantly large or there are other concerning symptoms.

Choice B rationale:

A client scheduled for a colonoscopy and taking sodium phosphate does not typically require follow-up care for the sodium phosphate intake itself. Sodium phosphate is commonly used as a bowel prep medication to clear the intestines prior to the procedure.

Choice C rationale:

A potassium level of 3.6 mEq/L is within the normal range (3.5-5.0 mEq/L), so a client taking bumetanide with this potassium level would not typically require follow-up care for the potassium level alone.

Choice D rationale:

A client taking warfarin with an INR of 1.8 requires follow-up care because the therapeutic range for warfarin is typically between 2.0 and 3.0 for most indications. An INR of 1.8 may indicate that the blood is not “thin” enough, increasing the risk of thrombotic events, and the warfarin dose may need adjustment.
