Correct Answer: B

Rationale: The correct answer is 'serving as the expert for resource utilization.' While physicians play a crucial role in case management, their primary focus is on medical diagnosis and treatment rather than resource utilization. Choices A, C, and D are all roles that physicians typically fulfill in case management. A physician participating in interdisciplinary planning for clients ensures comprehensive care, consulting with the case management team helps in coordinating timely orders, and contributing to the documentation of a client's needs for services aids in providing appropriate care. Therefore, serving as the expert for resource utilization does not align with the primary responsibilities of a physician in case management.

Correct Answer: B

Rationale: Mammography is specifically used to detect tumors or abnormal growths, especially in breast tissue. It is not a tool for identifying pain, edema, or epilepsy. Therefore, the correct answer is 'tumor.' Pain is a symptom, edema is swelling, and epilepsy is a neurological disorder; none of these are conditions typically detected through mammography.

Correct Answer: A

Rationale: In a situation where a client has no family members and the client's wife is mentally incompetent, the healthcare provider may write a DNR order if it is deemed medically certain that resuscitation would be futile. A DNR order is a medical directive that instructs healthcare providers not to perform CPR if a patient's heart stops or if the patient stops breathing. Option A is correct because a DNR order can indeed be issued by a healthcare provider under certain circumstances, as it is a medical decision. Options B, C, and D are incorrect as they do not accurately reflect the concept of DNR orders and the decision-making process involved in such situations.

Correct Answer: D

Rationale: The correct answer is 'To be aware of the role of the licensed nurse.' Nurse practice acts outline the scope of practice for nurses, defining what constitutes nursing practice and the role of licensed nurses. Choice A is incorrect because hospital and long-term care facility policies are institution-specific and not typically covered in the nurse practice act. Choice B is incorrect as the scope of practice for nurses is a part of the nurse practice act, but it's not the sole purpose for a nurse to refer to it. Choice C is incorrect as health care policies in a state are governed by other legislative acts, not the nurse practice act.

Correct Answer: D

Rationale: Breast implants can interfere with mammography by potentially preventing the detection of masses. The presence of implants can obscure a clear view of breast tissue, making it difficult to identify abnormalities such as masses that may indicate breast cancer. Choices A, B, and C are incorrect because discomfort, contraindications, and dislodgment are not primary reasons why breast implants interfere with mammography. The main concern is the impedance of detecting abnormalities accurately due to the implants.
