Correct Answer: A

Rationale: The correct answer is A: 135 to 145 milliequivalents per liter. The normal range for sodium levels in the body is expressed in milliequivalents per liter, not microequivalents. Choice B and D provide a significantly lower range which is not within the normal values for sodium. Choice C incorrectly states 'microequivalents' instead of the correct unit 'milliequivalents'. Therefore, A is the correct answer.

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.

Correct Answer: C

Rationale: After a client complains of nausea and vomits one hour after taking glyburide, the priority nursing intervention should be to monitor blood glucose closely and look for signs of hypoglycemia. Vomiting could indicate that the glyburide was not properly absorbed, potentially leading to hypoglycemia. Administering glyburide again (Choice A) could worsen hypoglycemia. Administering subcutaneous insulin (Choice B) is not appropriate without assessing the blood glucose first. Monitoring for signs of hyperglycemia (Choice D) is not the immediate concern in this situation.

Correct Answer: B

Rationale: The correct answer is B: 'Coordinating patient care with other team members.' In a multidisciplinary healthcare team, nurses collaborate with other healthcare professionals to ensure comprehensive care for patients. Working independently without consulting others (choice A) is not aligned with the collaborative nature of multidisciplinary teams. Ignoring patient concerns (choice C) goes against the core principles of patient-centered care. Making all healthcare decisions alone (choice D) contradicts the teamwork approach of a multidisciplinary team.

Correct Answer: D

Rationale: Orthostatic hypotension and flat neck veins are classic manifestations of fluid volume deficit. When the body loses fluid, blood volume decreases, leading to decreased venous return to the heart, resulting in orthostatic hypotension and flat neck veins. Choices A, B, and C are more indicative of other conditions such as dehydration, respiratory issues, or compensatory mechanisms in response to hypovolemia, respectively.
