A nurse enters a client's room to administer medication and finds the client lying in bed disoriented with labored and fast respirations. Which of the following actions should the nurse take first?

A. Encourage the client to drink 8 glasses of water a day.

This is the correct choice. Clients with COPD often have thickened respiratory secretions due to chronic inflammation and mucus production. Adequate hydration helps to keep these secretions thin, making them easier to cough up and clear from the airways. Encouraging the client to drink plenty of fluids, such as water, can assist in maintaining optimal hydration levels and promoting effective airway clearance.

B. Instruct the client to cough every 4 hours.

Instructing the client to cough on a scheduled basis, such as every 4 hours, is not appropriate for managing COPD. While coughing is important for clearing respiratory secretions, the frequency of coughing should be based on the client's individual needs and symptoms. Some clients with COPD may need to cough more frequently, while others may need to cough less often. It's important to encourage the client to cough as needed to clear secretions rather than on a predetermined schedule.

C. Provide the client with a low-protein diet.

Providing the client with a low-protein diet is not recommended for managing COPD. Adequate protein intake is important for maintaining muscle strength, including respiratory muscles, and supporting overall health. Clients with COPD may have increased energy needs due to the increased work of breathing and should be encouraged to consume a balanced diet that includes adequate protein.

D. Advise the client to lie down after eating.

Advising the client to lie down after eating is not recommended for managing COPD. Lying down after eating can increase pressure on the diaphragm and make breathing more difficult, especially for individuals with compromised lung function. It's generally recommended for individuals with COPD to remain in an upright position after eating to minimize respiratory discomfort and reduce the risk of aspiration.

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.
