A nurse is collecting data from a client prior to administering metoprolol. For which of the following findings should the nurse withhold the medication?

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. Open access peer-reviewed articles must be purchased by the user: This is not accurate. Open access articles are freely available to the public and do not require purchase.

B. Editorial opinion articles by journalists can be as relevant as peer-reviewed articles: While editorial opinion articles can provide valuable insights, they are not subjected to the same rigorous review process as peer-reviewed articles. Therefore, they are not considered as reliable or authoritative as peer-reviewed articles.

C. Peer-reviewed articles are not considered scholarly sources of evidence: This is incorrect. Peer-reviewed articles are considered one of the highest levels of scholarly sources of evidence. They have been reviewed and approved by experts in the field before publication.

D. Peer-reviewed articles have been through laborious review by other professionals: This is correct. Peer-reviewed articles undergo a rigorous review process by experts in the field, ensuring the research is of high quality and the findings are valid.
