Correct Answer: B

Rationale: The correct answer is B. Second-degree atrioventricular heart block is also known as Mobitz II. In Mobitz II, some atrial impulses are blocked from reaching the ventricles, resulting in occasional dropped beats. Third-degree atrioventricular heart block is known as complete heart block, where no atrial impulses reach the ventricles. First-degree atrioventricular heart block is a condition where there is delayed conduction between the atria and ventricles but all atrial impulses are eventually conducted to the ventricles.

Correct Answer: C

Rationale: In a triage situation, an asymmetrical thorax suggests a potentially life-threatening condition such as a pneumothorax or hemothorax, requiring immediate attention. This client should be tagged as emergent. Periorbital ecchymosis and deep-partial thickness burns, while concerning, may not indicate an immediate life-threatening situation. An open fracture of the femur, although serious, can be prioritized after addressing emergent cases.

Correct Answer: A

Rationale: The correct answer is A: Violated the law. Taking and sharing patient photographs without consent is a violation of patient privacy laws, hence the nurse was fired for breaking the law. Choice B, acting in a negligent manner, is incorrect as the nurse's actions were intentional and not due to negligence. Choice C, not completing proper documentation, is unrelated to the situation described. Choice D, violating an ethical principle, is not specific enough as the primary reason for the nurse's termination was the legal breach regarding patient privacy.

Correct Answer: D

Rationale: Pouching a new colostomy is a task that can be safely and appropriately delegated to an assistive personnel as it falls within their scope of practice. Measuring oxygen saturation (Choice A) requires a higher level of training and assessment, making it unsuitable for delegation. Inserting a rectal suppository (Choice B) and performing nasal hygiene (Choice C) involve invasive procedures that are typically performed by licensed nursing staff due to the associated risks and complexities, making them inappropriate for delegation to assistive personnel.

Correct Answer: A

Rationale: The correct answer is A: 'Acute angle-closure glaucoma is an ocular emergency.' Acute angle-closure glaucoma is indeed considered an ocular emergency that requires immediate attention to prevent vision loss. Choice B is incorrect because acute angle-closure glaucoma commonly presents with symptoms like severe eye pain, headache, blurred vision, and halos around lights. Choice C is incorrect as these symptoms are more indicative of acute angle-closure glaucoma rather than primary open-angle glaucoma. Choice D is incorrect since bubbles are not typically used to protect the retina from glaucoma; treatment usually involves medications, laser therapy, or surgery to manage intraocular pressure.
