OR nurses should be aware that maintaining the client's safety is the overall goal of nursing care during the intraoperative phase. As the circulating nurse, you make certain that throughout the procedure…

Correct Answer: C

Rationale: The correct answer is C because securing straps around the client's knees, ankles, and hands on an arm board is crucial for maintaining the client's safety during surgery. This helps prevent inadvertent movements that could lead to injury or interference with the surgical procedure. Straps made of strong, non-abrasive materials ensure comfort and proper positioning. A: The surgeon greeting the client before anesthesia induction is not directly related to maintaining the client's safety during surgery. B: The coordination between the surgeon and anesthesiologist is important but does not directly address the client's safety during the intraoperative phase. D: While monitoring by the assistant anesthesiologist is important, it is the responsibility of the circulating nurse to ensure physical safety measures are in place.

Correct Answer: B

Rationale: The correct answer is B because as the nurse in charge of scheduling surgical cases, it is crucial to know the surgeon's preferred time and type of surgery, as well as the names of their assistant and anesthesiologist. Knowing this information ensures proper coordination and preparation for the surgical procedure. Choice A is incorrect because knowing the internist is not directly relevant to scheduling surgical cases. Choice C is incorrect because the question specifically asks about important information for scheduling surgical cases, not about general medical personnel involved. Choice D is also incorrect as it only focuses on the anesthesiologist and omits other essential information needed for scheduling.

Correct Answer: B

Rationale: The correct answer is B: Sensation of pressure. Patients with ileostomy rely on the sensation of pressure to determine when to drain their pouch. As the pouch fills up with stool, they feel a sense of fullness or pressure, indicating the need for emptying. This sensation serves as a practical guide for maintaining pouch hygiene. Other choices like A (taste), C (smell), and D (urge to defecate) are not relevant in this context as they do not directly relate to the physical indication of when the pouch needs to be drained. Taste and smell are sensory perceptions, while the urge to defecate is a natural bodily function that is altered in patients with ileostomy.

Correct Answer: D

Rationale: The correct answer is D because nitroglycerin works by dilating veins, decreasing venous return to the heart, and reducing preload. This reduces the workload of the heart and oxygen demand, relieving angina. Choice A is incorrect because nitroglycerin does not increase contractility but rather decreases it. Choice B is incorrect because nitroglycerin does not increase AV conduction or heart rate. Choice C is incorrect because nitroglycerin does not decrease contractility or oxygen consumption.

Correct Answer: A

Rationale: The correct answer is A: Acute asthma. The client's presentation of tachypnea, nonproductive cough, and recent cold is suggestive of an acute asthma exacerbation. Asthma commonly presents with these symptoms, especially in children. The absence of fever and productive cough makes bronchial pneumonia less likely. COPD and emphysema are typically seen in older individuals with a history of smoking, not in a 7-year-old child. Therefore, based on the client's age, symptoms, and absence of other risk factors, acute asthma is the most likely diagnosis.
