Rationale: The DRG manual is used to determine the reimbursement rate for medical diagnoses and treatments under the prospective payment system used by healthcare facilities. Choice A is incorrect because the DRG manual is not used to classify nursing diagnoses, but rather to group medical diagnoses for billing purposes. Choice B is incorrect as the DRG manual is not used to identify findings related to medical diagnoses, but rather to standardize payments for medical services. Choice D is incorrect as the DRG manual is not used to implement nursing care based on case management protocol, but rather to set reimbursement rates.

Rationale: The correct answer is A: Leukopenia. Methotrexate, used in the treatment of rheumatoid arthritis, can lead to bone marrow suppression, resulting in leukopenia. This condition increases the risk of infections due to decreased white blood cell count. Choices B, C, and D are incorrect because methotrexate is not known to cause hyperglycemia, hypertension, or hypokalemia as its primary adverse effects.

Correct Answer: C

Rationale: The primary function of a public health nurse is to promote and protect the health of populations. Public health nurses focus on preventing diseases, promoting healthy behaviors, and addressing health disparities within communities. Providing bedside care (choice A) is typically done by nurses in clinical settings, not public health nurses. Administering medications (choice B) is part of nursing practice but not the primary role of a public health nurse. Performing surgical procedures (choice D) is usually the responsibility of surgical nurses or healthcare providers specializing in surgery, not public health nurses.

Correct Answer: D

Rationale: In severe depression, the priority nursing diagnosis is safety. Individuals with severe depression are at risk of self-harm or suicide. Ensuring the client's safety by implementing measures to prevent harm to themselves or others is crucial. While nutrition, elimination, and activity are important aspects of care, ensuring the client's immediate safety takes precedence in this situation.

Correct Answer: A

Rationale: The correct answer is A: Insufficient oxygenation of the cardiac muscle. Myocardial infarction pain is primarily caused by inadequate oxygen reaching the heart muscle, leading to ischemia and tissue damage. Choices B, C, and D are incorrect because circulatory overload, left ventricular overload, and electrolyte imbalance are not the primary causes of chest pain in myocardial infarction. Circulatory overload may lead to other symptoms like edema, left ventricular overload can result in heart failure symptoms, and electrolyte imbalance may present with various manifestations, but none of these directly cause the characteristic chest pain associated with an MI.
