The sterile nurse or sterile personnel touch only sterile supplies and instruments. When there is a need for sterile supply which is not in the sterile field, who hands out these items by opening its outer cover?

Correct Answer: A

Rationale: The correct answer is A: Circulating Nurse. The circulating nurse is responsible for handing out sterile supplies that are not within the sterile field by opening its outer cover. This is to maintain the sterility of the items being used in the surgical field. The circulating nurse's role is crucial in preventing contamination and ensuring patient safety during surgical procedures. Summary: - A: Circulating Nurse (Correct): Responsible for providing sterile supplies from outside the sterile field. - B: Anaesthesiologist (Incorrect): Not typically responsible for handling sterile supplies. - C: Surgeon (Incorrect): Focuses on the surgical procedure and does not usually handle sterile supplies. - D: Nursing Aide (Incorrect): Not typically involved in handling sterile supplies during surgical procedures.

Correct Answer: B

Rationale: The correct answer is B - check for presence of dentures. This is crucial to prevent aspiration of dentures during intubation. Checking for underwear (A) is not directly related to patient safety during anesthesia. Checking patient's ID (C) is important for identification but not a priority pre-anesthesia. Checking baseline vital signs (D) is essential, but not specific to preventing complications related to dentures.

Correct Answer: D

Rationale: The correct answer is D: Practice respiratory isolation. This is the correct answer because respiratory isolation is not a standard health instruction for managing bronchial asthma. The other choices (A, B, C) are all essential instructions for managing asthma. Avoiding emotional stress and extreme temperatures can help prevent asthma attacks. Avoiding pollution like smoking can reduce exposure to irritants that can trigger asthma symptoms. Avoiding allergens like pollens, dust, and seafood can also help prevent asthma exacerbations. In summary, respiratory isolation is not a relevant or effective health instruction for managing bronchial asthma, unlike the other choices which are important for asthma management.

Correct Answer: D

Rationale: Step 1: In the operating room (OR), the two main roles are scrub nurse and circulating nurse. Step 2: Scrub nurse assists the surgeon directly during the procedure. Step 3: Circulating nurse manages the overall OR environment and patient safety. Step 4: Together, they form a complete nursing tandem for every surgery. Step 5: Option D includes both roles, making it the correct answer. Summary: - Option A includes only the instrument technician and circulating nurse, missing the scrub nurse. - Option B includes additional roles like nurse anesthetist and nurse assistant, which are not part of the essential nursing tandem. - Option C includes scrub nurse and nurse anesthetist, missing the circulating nurse role essential for patient safety.

Correct Answer: C

Rationale: The correct answer is C: General population. A sample group represents a subset of the general population that is used to draw conclusions about the population as a whole. The sample should be representative of the general population to ensure the validity of the study results. A: Control group refers to a group in an experiment that does not receive the experimental treatment. B: Study subjects are individuals participating in a study or experiment. D: Universe refers to the entire population being studied, which is broader than the sample group. Therefore, the correct answer is C as it best describes what a sample group represents in research studies.
