Which of the following role would be the responsibility of the scrub nurse?

Correct Answer: C

Rationale: The correct answer is C because the responsibility of the scrub nurse is to account for the number of sponges, needles, and supplies used during the surgical procedure. This is crucial for patient safety and to prevent any foreign objects from being left inside the patient. Explanation: A: Assessing the readiness of the client prior to surgery is typically the responsibility of the pre-op nurse or the circulating nurse, not the scrub nurse. B: Ensuring that the airway is adequate is the responsibility of the anesthesiologist or anesthesia provider, not the scrub nurse. D: Evaluating the type of anesthesia appropriate for the surgical client is the responsibility of the anesthesia provider, not the scrub nurse.

Correct Answer: C

Rationale: The correct answer is C: Circulating Nurse. During surgery, the circulating nurse is responsible for coordinating activities outside the operating room, including communicating with the family. They ensure the smooth flow of the surgical procedure, handle documentation, equipment, and communication. The other choices are incorrect because: A: Orderly/clerk is not typically involved in coordinating activities outside the operating room. B: Nurse Supervisor focuses on managing the nursing staff and overseeing patient care within the unit, not specifically coordinating activities outside during surgery. D: Anesthesiologist is primarily responsible for administering anesthesia and monitoring the patient's vital signs during surgery, not coordinating activities with the family.

Correct Answer: B

Rationale: The correct answer is B: An equal chance of selection. Random sampling ensures that each subject in the population has an equal probability of being selected for the sample, which helps in reducing bias and obtaining a representative sample. This increases the generalizability of the findings to the entire population. A: Being selected systematically does not guarantee each subject an equal chance of selection. C: Being selected based on set criteria is not random and may introduce bias. D: Having characteristics that match other samples does not ensure equal chance of selection for each subject in the population.

Correct Answer: A

Rationale: The correct answer is A: Stop the I.V. infusion of heparin and notify the physician. Heparin is an anticoagulant that prolongs the PTT. A PTT of 68 seconds indicates that the client may be at risk for bleeding due to excessive anticoagulation. Stopping the heparin infusion is crucial to prevent further complications. Notifying the physician is essential for further management. B: Continuing treatment as ordered would pose a risk of potential bleeding complications due to excessive anticoagulation. C: Warfarin affects the INR, not the PTT. Expecting warfarin to increase the PTT is incorrect. D: Increasing the dosage of heparin is contraindicated as the PTT is already elevated, indicating a risk of bleeding.

Correct Answer: C

Rationale: The correct answer is C: Presence of premature ventricular contractions (PVCs) on a cardiac monitor. Lidocaine is commonly used to treat PVCs and ventricular arrhythmias. Monitoring for PVCs is crucial to assess the effectiveness of the medication. A decrease in arterial oxygen saturation (A) is not directly related to lidocaine administration. An increase in systemic blood pressure (B) is not a primary concern with lidocaine. Increase in intracranial pressure (ICP) (D) is not directly affected by lidocaine administration.
