In the operating room, personnel should be responsible for ensuring cleanliness, proper temperature, humidity, and lighting. Who carries those responsibilities?

Correct Answer: A

Rationale: The correct answer is A: circulating nurse. The circulating nurse is responsible for maintaining cleanliness, ensuring proper temperature, humidity, and lighting in the operating room. They coordinate activities, manage supplies, and ensure a safe environment for the surgical team. The scrub nurse assists the surgeon with instruments and supplies, not environmental conditions. The surgeon's main focus is on performing the surgery, not environmental management. The anesthesiologist is responsible for administering anesthesia and monitoring the patient's vital signs, not the operating room environment.

Correct Answer: B

Rationale: The correct answer is B: Pupil responses. During an ophthalmic assessment, observing pupil responses is crucial as it provides information on the function of the cranial nerves and potential neurological issues. Pupil size, shape, symmetry, and reaction to light are key indicators of eye health. A: Level of central vision - While important, assessing the level of central vision is typically done by the ophthalmologist and not within the scope of the nurse's role in a routine assessment. C: External eye appearance - Although external eye appearance can give some clues about eye health, it is not as direct and crucial as observing pupil responses. D: Eye movements - While eye movements can provide information on ocular motor function, it is not as critical as assessing pupil responses in an ophthalmic assessment.

Correct Answer: A

Rationale: The correct answer is A: status of client’s tetanus immunization. It is critical because an open fracture poses a risk of infection, and tetanus prophylaxis is necessary to prevent tetanus infection. Tetanus is caused by a bacterium commonly found in soil and can enter the body through open wounds. Assessing the client's tetanus immunization status helps determine the need for a tetanus booster to prevent potential complications. Incorrect choices: B: Current blood alcohol level - While relevant to the situation, the priority in this case is preventing infection from the open fracture. C: Support systems available at home to assist with care - Important for discharge planning but not the immediate priority. D: Last time client voided - Not critical in this scenario compared to preventing infection from the open fracture.

Correct Answer: A

Rationale: The correct answer is A because it meets the goal of maintaining a heart rate of 78 beats/min. This specific date ensures the consistency of the heart rate within the desired range. Choices B, C, and D do not align with the goal as they either have a different heart rate or occur on a different date. Therefore, A is the only option that accurately reflects the goal being met on the specified date.

Correct Answer: A

Rationale: The correct answer is A: Anthropometric measurements. This includes height, weight, and body mass index, which are crucial indicators of the nutritional status of a patient with Crohn's disease. It helps assess malnutrition, muscle wasting, and overall nutritional health. Dry skin (B), bleeding gums (C), and facial rubor (D) are not direct indicators of nutritional health in a patient with Crohn's disease. Dry skin may indicate dehydration, bleeding gums may suggest poor oral hygiene or gum disease, and facial rubor may be a sign of inflammation but are not specific to nutritional status.

Correct Answer: A

Rationale: The correct answer is A: It inhibits deoxyribonucleic acid (DNA) synthesis. Mitomycin works by cross-linking DNA, leading to inhibition of DNA synthesis and ultimately causing cell death. This mechanism of action makes it effective against rapidly dividing cancer cells. B: It’s cell cycle-phase specific - This is incorrect because mitomycin is not specific to a particular phase of the cell cycle. C: It inhibits ribonucleic acid (RNA) synthesis - This is incorrect as mitomycin primarily targets DNA synthesis, not RNA synthesis. D: It inhibits protein synthesis - This is incorrect as mitomycin's main mechanism of action is through DNA cross-linking, not protein synthesis inhibition.

Correct Answer: A

Rationale: Rationale: A: Pressing the system in place for 30 to 60 seconds helps ensure proper adhesion and absorption of the medication. This step is crucial for the effectiveness of the pain management system. B: Choosing a site on the lower torso is not necessary for applying the system. The site selection should be based on guidelines and patient preference. C: Shaving the application site is not recommended unless specifically indicated. It is not a standard step for applying a pain management system. D: Applying the system immediately after removal from a package may not allow the adhesive to fully activate, affecting its efficacy. It is important to follow the recommended steps for proper application.

Correct Answer: B

Rationale: The correct answer is B because monitoring the site and progress of the infusion every hour is crucial to prevent complications like infiltration or infection in clients with hypertension. Choice A is incorrect as checking BP every hour is excessive. Choice C is incorrect as daily monitoring may not detect issues promptly. Choice D is incorrect as pulse rate monitoring is not directly related to IV fluid administration in this context. Monitoring the site and progress hourly ensures timely intervention if any issues arise.

Correct Answer: B

Rationale: The correct answer is B: Use two people to assist the patient. This is the safest option as it provides optimal support and stability for the patient during their first postoperative ambulation. Two people can help prevent falls, ensure proper body mechanics, and offer immediate assistance if needed. Using one person (choice A) may not provide enough support. Encouraging the patient to "dangle" (choice C) may increase the risk of orthostatic hypotension. Giving a narcotic before ambulation (choice D) can impair the patient's balance and coordination, increasing the risk of falls.
