A nurse is caring for a client who has a prescription for diltiazem. The nurse measures the client's vital signs and notes that the client's apical heart rate is 49/min. The nurse should prepare to administer which of the following medications?

Atropine

Verapamil

Digoxin

Carvedilol

Answer and Explanation

The Correct Answer is A

A) Atropine:
Atropine is a medication used to increase heart rate. It acts by blocking the parasympathetic nervous system, leading to increased heart rate. It is commonly used to treat bradycardia, which is characterized by a heart rate less than 60 beats per minute. In this scenario, with the client's apical heart rate at 49/min, indicating bradycardia, the nurse should prepare to administer atropine to increase the heart rate.

B) Verapamil:
Verapamil is a calcium channel blocker that can decrease heart rate. It is used to treat various cardiac conditions, but it is not appropriate for a client with bradycardia, as it would further lower the heart rate.

C) Digoxin:
Digoxin is a medication used to treat heart failure and certain arrhythmias, but it does not directly increase heart rate. In fact, it can exacerbate bradycardia in some cases.

D) Carvedilol:
Carvedilol is a beta-blocker that can decrease heart rate. It is used to treat hypertension, heart failure, and other cardiovascular conditions, but it is not appropriate for a client with bradycardia, as it would further lower the heart rate.

Correct Answer is C

Explanation

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. B. Editorial opinion articles by journalists can be as relevant as peer-reviewed articles C. Peer-reviewed articles are not considered scholarly sources of evidence. D. Peer-reviewed articles have been through laborious review by other professionals.

Correct Answer is D

Explanation

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.
