Correct Answer: C

Rationale: The correct answer is C: Malpractice. Malpractice refers to professional negligence or failure to perform duties according to accepted standards of practice. In this scenario, the surgeon's act of cutting the patient's bladder during an appendectomy could be considered a breach of duty and failure to provide the expected standard of care, which falls under malpractice. Battery (A) involves intentional harmful or offensive contact without consent. Negligence (B) is the failure to exercise reasonable care, but in this case, it was more than just a lack of care. Tort (D) refers to a civil wrong that causes harm, but malpractice is a specific type of tort related to professional negligence.

Correct Answer: B

Rationale: The correct answer is B: Initiate non-invasive positive pressure ventilation (NIPPV) for respiratory support. In acute exacerbations of COPD, NIPPV helps improve ventilation and oxygenation, reducing the work of breathing and preventing the need for intubation. This intervention is a priority as it can rapidly stabilize the patient's respiratory status. A: Administering bronchodilator medications is important in COPD management, but in severe exacerbations, NIPPV takes precedence. C: Arterial blood gas analysis is important for assessing oxygenation and ventilation status, but it does not directly address the acute respiratory distress. D: Chest physiotherapy can help with airway clearance in COPD, but in acute exacerbations, respiratory support with NIPPV is more urgent.

Correct Answer: B

Rationale: The correct answer is B: Psoriasis. Psoriasis is characterized by pruritic, erythematous patches with silvery scales, commonly found on the elbows, knees, and scalp. This presentation matches the patient's symptoms. Eczema (choice A) typically presents with red, inflamed, and itchy skin patches. Pityriasis rosea (choice C) manifests as a herald patch followed by smaller scaly patches in a "Christmas tree" distribution. Seborrheic dermatitis (choice D) involves oily, yellowish, scaly patches mainly on the scalp, face, and ears, and does not typically present with silvery scales.

Correct Answer: B

Rationale: The primary goal of CPR is to restore spontaneous circulation and oxygenation to the body to maintain vital organ function. By performing chest compressions and rescue breaths, CPR aims to circulate oxygenated blood to the brain and other vital organs. This is crucial to prevent brain damage and increase the chances of survival. The other choices are incorrect because CPR does not address the underlying cause of cardiac arrest (A), provide pain relief (C), or prevent further complications such as organ failure (D). The immediate focus in a cardiac arrest situation is to maintain blood flow and oxygen delivery to vital organs until advanced medical care can be provided.

Correct Answer: C

Rationale: The correct answer is C because positioning oneself at eye level helps the patient see the nurse's facial expressions and lip movements, aiding in communication. Speaking clearly and slowly allows the patient to better understand. Speaking loudly can distort sound and may not be necessary. Avoiding visual aids or gestures limits communication channels. Speaking quickly can overwhelm the patient and hinder comprehension.
