Question

The nurse is explaining the use of anticholinergics as preoperative medications to the patient. Which explanation for use of anticholinergics is most appropriate?

Answers

  1. The medication helps with sedation.
    • Rationale:

      This answer is not correct because anticholinergics are not administered preoperatively to help with sedation. Anticholinergics are administered to decrease respiratory secretions. This helps reduce the risk of aspiration during and after surgery and reduces nausea and vomiting.

  2. The medication helps reduce gastric acid production.
    • Rationale:

      This answer is not correct because anticholinergics are not administered preoperatively to help reduce gastric acid production. A H2 inhibitor, such as famotidine, is given to decrease gastric acid production. Anticholinergics are administered to decrease respiratory secretions. This helps reduce the risk of aspiration during and after surgery and reduces nausea and vomiting.

  3. The medication helps decrease respiratory secretions.
    • Rationale:

      This answer is correct because anticholinergics are administered to decrease respiratory secretions. This helps reduce the risk of aspiration during and after surgery and reduces nausea and vomiting.

  4. The medication helps reduce anxiety.
    • Rationale:

      This answer is not correct because anticholinergics are not administered preoperatively to reduce anxiety. Benzodiazepine medications are administered to help reduce anxiety. Anticholinergics are administered to decrease respiratory secretions. This helps reduce the risk of aspiration during and after surgery and reduces nausea and vomiting.

Overview

Anticholinergics are given preoperatively to help decrease respiratory secretions.

Explanation

The correct answer is C. Anticholinergics decrease respiratory tract secretions, helps dry mucous membranes, and may help decrease or interrupt vagal stimulation. Anticholinergics do not help with gastric acid, sedation, or anxiety.

Learning Outcomes

Anticholinergics are used for various purposes, including preoperative purposes. These medications are administered to decrease respiratory secretions. This helps reduce the risk of aspiration during and after surgery and reduces nausea and vomiting. Side effects of anticholinergics include blurred vision, dry mouth, urinary retention, and constipation. The patient should be taught these side effects.

Test Taking Tip

Because few things in life are absolute without exceptions, avoid selecting answers that include words such as always, never, all, every, and none. Answers containing these keywords are rarely correct.
