A nurse is discussing the process of evidence-based practice with a newly licensed nurse. Which of the following information should the nurse include when discussing a PICOT question?

Answer: C. Respiratory acidosis

Rationale:

A) Metabolic acidosis: This occurs when there is an excess of acid in the body or a loss of bicarbonate, often due to conditions such as renal failure or severe diarrhea. In chronic bronchitis, the primary issue is related to respiratory function rather than metabolic disturbances.

B) Respiratory alkalosis: This condition results from hyperventilation, leading to excessive loss of carbon dioxide. It is unlikely in a client with chronic bronchitis, who typically experiences difficulty in exhaling fully rather than hyperventilating.

C) Respiratory acidosis: In chronic bronchitis, airflow obstruction and reduced gas exchange can lead to carbon dioxide retention, resulting in respiratory acidosis. Symptoms like dyspnea and increased work of breathing support this imbalance, as the body is unable to adequately expel carbon dioxide.

D) Metabolic alkalosis: This imbalance results from excessive bicarbonate or loss of hydrogen ions, often related to prolonged vomiting or diuretics. It is not characteristic of chronic bronchitis, where the primary concern is respiratory function rather than metabolic processes.

(A) Determine the client’s blood pressure 1 min after each position change: While it’s important to check the client’s blood pressure after each position change when assessing for orthostatic hypotension, this is not the first step. The nurse should first establish a baseline blood pressure reading with the client in a supine position.

(B) Place the client in a sitting position: Although the nurse will eventually need to check the client’s blood pressure in a sitting position, the first step is to get a baseline reading with the client in a supine position.

(C) Assist the client into a standing position: The nurse will eventually assist the client into a standing position to check for changes in blood pressure, but this is not the first step. The initial step is to get a baseline reading with the client in a supine position.

(D) Check the blood pressure with the client in a supine position: This is the most appropriate first step. When checking for orthostatic hypotension, the nurse should first check the client’s blood pressure while they are lying flat (supine). This provides a baseline reading against which subsequent readings (taken when the client is sitting and standing) can be compared. If there’s a significant drop in blood pressure upon standing, this could indicate orthostatic hypotension.
