A nurse is collecting data on a client who has obstructive sleep apnea. Which of the following findings should the nurse expect?

A. Liver function tests

This is the correct choice. Pyrazinamide, a medication used in the treatment of tuberculosis, is known to potentially cause hepatotoxicity, which refers to liver damage or dysfunction. Therefore, clients prescribed pyrazinamide should undergo regular monitoring of liver function tests to assess for any signs of liver injury or impairment. Liver function tests typically include measurements of various enzymes and proteins produced by the liver, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and bilirubin levels.

B. Gallbladder studies

Gallbladder studies are not typically indicated for clients taking pyrazinamide. While pyrazinamide can rarely cause hepatotoxicity, which may affect liver function, it is not known to specifically target or affect the gallbladder. Therefore, routine gallbladder studies are not necessary for clients taking pyrazinamide.

C. Thyroid function studies

Pyrazinamide is not known to directly affect thyroid function. Therefore, routine thyroid function studies are not indicated for clients taking pyrazinamide unless there are specific signs or symptoms suggesting thyroid dysfunction.

D. Blood glucose levels

Pyrazinamide is not known to directly affect blood glucose levels. Therefore, routine monitoring of blood glucose levels is not indicated for clients taking pyrazinamide unless there are specific reasons to suspect or monitor for diabetes mellitus or other conditions affecting blood glucose regulation.

A. Constipation

Constipation is not typically associated with obstructive sleep apnea. However, sleep disturbances and certain medications used to manage OSA may indirectly contribute to constipation in some cases.

B. Nausea

Nausea is not a common symptom of obstructive sleep apnea. While sleep disturbances may affect gastrointestinal function in some individuals, nausea is not a typical manifestation of OSA.

C. Headache

One of the common findings associated with obstructive sleep apnea (OSA) is headache. This occurs due to the repeated episodes of apnea (cessation of breathing) during sleep, which leads to intermittent hypoxia (low oxygen levels) and subsequent cerebral vasodilation. The vasodilation can trigger headaches, often described as morning headaches, upon waking up. These headaches are typically frontal and may be accompanied by other symptoms such as fatigue and irritability.

D. Hypotension

Hypotension (low blood pressure) is not a typical finding in obstructive sleep apnea. In fact, individuals with OSA are more likely to have hypertension (high blood pressure) due to the effects of repeated apnea episodes on the cardiovascular system, such as increased sympathetic activity and arterial stiffness.
