Correct Answer: A

Rationale: Lethargy is a critical finding that requires the nurse's immediate attention when a client with a recent skull fracture is readmitted to the hospital. It can indicate increased intracranial pressure or other serious complications such as hemorrhage or infection. Addressing lethargy promptly is crucial to prevent further deterioration. Agitation, ataxia, and hearing loss are important to assess but do not signify the same level of urgency as lethargy in this context.

Correct Answer: A

Rationale: The correct answer is A: 'Differences in health outcomes and their determinants between different segments of the population.' Health disparity refers to variations in health status or health care utilization between different groups. Choice B is incorrect because providing equal healthcare services to all individuals is related to health equity, not health disparity. Choice C is also incorrect as it refers to universal access to healthcare, which is different from health disparity. Choice D is incorrect as it describes the concept of high-quality healthcare for everyone, not health disparity.

Correct Answer: C

Rationale: Individuals with cognitive impairment often experience difficulties in learning new information, creative thinking, and making sound judgments. Loss of ability in hearing, speech, and sight (Choice A) is more closely related to sensory impairments rather than cognitive impairment. Endurance, strength, and mobility (Choice B) are more associated with physical capabilities rather than cognitive functions. Balance, flexibility, and coordination (Choice D) are related to motor skills and physical coordination, not cognitive impairment.

Correct Answer: C

Rationale: Consulting with human resources is the best approach in this situation. It ensures that the issue is handled according to the organization's policies and that the nurse receives the appropriate support and intervention needed for chemical dependency. Confronting the nurse directly may lead to defensiveness and hinder a constructive resolution. Scheduling a staff conference without the nurse present can create unnecessary speculation and violate the employee's privacy. Counseling the employee to resign is not appropriate and does not address the underlying problem of chemical dependency.

Correct Answer: C

Rationale: The correct answer is C: Hyperglycemia. Total parenteral nutrition (TPN) contains a high glucose content, which can lead to elevated blood sugar levels, resulting in hyperglycemia. Monitoring for hyperglycemia is crucial in clients receiving TPN to prevent complications such as osmotic diuresis, dehydration, and electrolyte imbalances. Choices A, B, and D are incorrect because TPN is more likely to cause hyperglycemia rather than hypoglycemia, hyperkalemia, or hyponatremia.
