Correct Answer: A

Rationale: The correct answer is A: emergency. Acute appendicitis is a condition that requires immediate surgical intervention to prevent complications like rupture. In an emergency surgery, the procedure must be done urgently to treat a life-threatening condition. In this case, the patient's symptoms indicate an urgent need for surgery to remove the inflamed appendix. Choice B: urgent, implies that surgery is needed promptly, but not immediately to prevent life-threatening complications. Choice C: elective, refers to a planned, non-urgent surgery that is scheduled in advance. Choice D: required, is a vague term and doesn't specify the urgency of the surgery, hence it is not the best classification for acute appendicitis surgery.

Correct Answer: D

Rationale: The correct answer is D because a brain abscess can be caused by direct invasion of the brain, spread of infection by other organs, and spread of infection from nearby sites. Direct invasion occurs when bacteria enter the brain tissue directly, such as through trauma or surgery. Infections from other organs, like the lungs or heart, can spread through the bloodstream to the brain. Infections from nearby sites, such as the ears or sinuses, can also spread to the brain. Therefore, all of these mechanisms can lead to the formation of a brain abscess. Choices A, B, and C individually do not cover all the possible causes of a brain abscess, making D the correct choice.

Correct Answer: D

Rationale: The correct answer is D, "Chest and nostrils." This is because observing the movement of the chest and nostrils is the most reliable way to determine if a patient is breathing. The chest rises and falls with each breath, and the nostrils may flare or move as air is inhaled and exhaled. Monitoring these areas provides a direct indication of respiratory effort. Choices A, B, and C are incorrect because they do not directly reflect the act of breathing. Extremities, head, and eyeball movements are not reliable indicators of breathing function.

Correct Answer: A

Rationale: The correct answer is A because it reflects a measurable and client-centered outcome. Verbalizing feelings of anxiety indicates the client is acknowledging and addressing their emotions, which is essential in managing anxiety. Choice B is incorrect as it focuses on avoidance rather than expression of emotions. Choice C is incorrect as it doesn't specify the use of appropriate coping mechanisms. Choice D is incorrect as it suggests avoidance of seeking information, which may hinder the client's understanding and coping with the diagnosis.

Correct Answer: A

Rationale: The correct answer is A: Where is the pain located? This question corresponds to the "P" in PQRST, which stands for Provocation/Palliation. By asking where the pain is located, the nurse is gathering information about what triggers or relieves the pain, aiding in the assessment of the chest pain. The other choices are incorrect because: B: What causes the pain? - This question corresponds to the "Q" in PQRST, which stands for Quality. It focuses on understanding the characteristics of the pain, not the cause. C: Does it come and go? - This question corresponds to the "R" in PQRST, which stands for Radiation. It pertains to whether the pain spreads to other areas, not if it comes and goes. D: What does the pain feel like? - This question corresponds to the "S" in PQRST, which stands for Severity. It relates to the intensity of the pain, not its location.
