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.

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: B

Rationale: Student nurses, licensed practical nurses, the Vice President for nursing investigating a fall, and quality assurance nurses have a 'need to know' basis to access patient records. Registered nurses who are not directly involved in the care of a patient do not have a legitimate reason or 'need to know' to access that patient's medical records, making choice B the correct answer. The Vice President for nursing investigating a specific incident and licensed practical nurses directly involved in a patient's care have legitimate reasons to access the medical records, ensuring continuity and quality of care.

Correct Answer: B

Rationale: The correct answer is to initiate cardiac monitoring. Severe hypokalemia can lead to life-threatening arrhythmias, making cardiac monitoring the priority to detect and manage any cardiac complications. Starting oxygen, seizure precautions, or bed rest are not the immediate priority actions for severe hypokalemia.

Correct Answer: B

Rationale: When dealing with a client exhibiting disruptive behavior like yelling obscenities, involving a family member can provide emotional support and help in de-escalating the situation. Keeping the client isolated in their room (Choice A) may lead to further agitation. Placing the client in a wheelchair (Choice C) or administering a sedative (Choice D) should not be the first interventions for managing behavioral issues.
