A nurse is caring for a client who has tuberculosis and is about to start taking pyrazinamide.
The nurse should identify that the client needs which of the following tests while taking this medication therapy?

Choice A rationale:

"I can plan to eat rice instead of baked potatoes.”. This choice demonstrates an understanding of dietary sources of potassium. Baked potatoes are a good source of potassium, and the client's willingness to substitute rice for baked potatoes indicates that they are aware of alternative potassium-rich foods. Potassium is essential for various bodily functions, including maintaining proper heart and muscle function. The client's willingness to make a dietary adjustment is a positive sign.

Choice B rationale:

"Adding pecans will be a change I can readily make.”. While pecans are a good source of potassium, this choice does not directly address the client's ability to substitute a potassium-rich food for one they might need to avoid. It focuses on a new addition to their diet rather than a substitution, making it a less relevant response to the teaching.

Choice C rationale:

"I will eat cantaloupe for my morning snack.”. Cantaloupe is indeed a good source of potassium, but this choice does not indicate an understanding of how to substitute potassium-rich foods in their diet. It only mentions adding cantaloupe as a snack without addressing the potential need for replacing other foods high in potassium. Therefore, it does not fully demonstrate comprehension of the teaching.

Choice D rationale:

"I will miss eating yogurt every day for breakfast.”. This choice expresses a sentiment but does not show an understanding of the teaching regarding dietary sources of potassium. It merely states that the client will miss yogurt without providing any insight into their ability to make appropriate dietary choices to maintain adequate potassium intake.

Choice A rationale:

Limiting fluid intake throughout the day is not a suitable instruction for a client diagnosed with emphysema. Emphysema is a chronic obstructive pulmonary disease (COPD), and adequate hydration is important for individuals with this condition. Dehydration can lead to thicker mucus in the airways, making it harder to breathe. Clients with emphysema should be encouraged to maintain proper hydration.

Choice B rationale:

Instructing the client to breathe in through her nose and out through pursed lips is a beneficial technique for improving gas exchange in emphysema. This breathing technique, known as pursed-lip breathing, helps slow down the exhalation and maintains positive pressure in the airways, which can prevent airway collapse. It also promotes better oxygen exchange and reduces the feeling of breathlessness.

Choice C rationale:

Consuming a low-protein diet is not advisable for a client with emphysema. Protein is essential for tissue repair and overall health. Clients with emphysema should follow a balanced diet to maintain their energy levels and support their respiratory function. Restricting protein intake is not a standard recommendation for managing emphysema.

Choice D rationale:

Instructing the client to rest in a supine position is not a suitable recommendation. Emphysema clients often find it easier to breathe when in an upright or semi-Fowler's position, as it allows for better lung expansion and oxygen exchange. Resting in a supine position can compromise their ability to breathe effectively and may worsen their symptoms.
