Chapter 20 Questions
Question 1 of 5
The nurse is preparing to administer atropine to a patient before surgery. Which of the following symptoms should the nurse teach the patient to expect?
Correct Answer: C
Rationale: Anticholinergic medications decrease oral and respiratory secretions, so the patient is taught that a dry mouth is an expected adverse effect. Weakness, forgetfulness, and dizziness are adverse effects associated with other preoperative medications such as opioids and benzodiazepines.
Question 2 of 5
Which of the following topics is most important for the nurse to discuss preoperatively with a patient who is scheduled for a colon resection?
Correct Answer: C
Rationale: Preoperative teaching, demonstration, and redemonstration of deep breathing and coughing are needed on patients having abdominal surgery to prevent postoperative atelectasis. Incisional care and the importance of completing antibiotics are better discussed after surgery, when the patient will be more likely to retain this information. The patient does not usually need information about medications that are used intraoperatively.
Question 3 of 5
The nurse is completing a preoperative assessment of a patient scheduled for a colon resection and the patient tells the nurse about using St. John's wort to prevent depression. Which of the following information should the nurse alert the staff in the postanaesthesia recovery area about?
Correct Answer: C
Rationale: St. John's wort may prolong the effects of anaesthetic agents and increase the time to waken completely after surgery. It is not associated with increased bleeding risk, hypertension, or increased pain.
Question 4 of 5
The nurse is conducting a preoperative interview with a patient who is scheduled for an elective hysterectomy and the patient tells the nurse, 'I am afraid that I will die in surgery like my mother did!' Which of the following responses by the nurse is most appropriate?
Correct Answer: A
Rationale: The patient's statement may indicate an unusually high anxiety level or a family history of problems such as malignant hyperthermia, which will require precautions during surgery. The other statements also may address the patient's concerns, but further assessment is needed first.
Question 5 of 5
The nurse is analyzing a patient's preoperative blood studies. Which of the following blood studies should the nurse review to assess for anemia and infection in a patient with no known health problems?
Correct Answer: A,B,D
Rationale: Preoperative blood studies for assessing anemia, immune status, and infection include RBC, Hgb, Hct, platelets, WBC, and WBC differential. Prothrombin (INR) time would be used to assess bleeding tendencies. Serum potassium would not be assessed as part of anemia or infection but would be assessed in a patient who is taking a diuretic.
