Adult Health Nursing Study Guide Answers

Correct Answer: C

Rationale: The nurse should prioritize checking the patency of the NG tube by aspirating gastric contents before initiating tube feeding. This is important to ensure that the NG tube is in the correct position and that it is functioning properly. By aspirating gastric contents, the nurse can confirm that the tube is in the stomach and not in the lungs or surrounding tissues. If no gastric contents are obtained upon aspiration, it may indicate that the tube is not properly placed or may be occluded, which would require further assessment and intervention before proceeding with tube feeding. Checking the patency of the NG tube is a crucial step in ensuring the safety and effectiveness of enteral nutrition delivery.

Correct Answer: A

Rationale: Total patient care model of nursing is focused on the task-oriented approach to client care. In this model, the nurse is responsible for all aspects of care for a group of patients during their shift. It involves providing direct care, coordinating with other healthcare team members, and overseeing the patients' overall well-being. This approach emphasizes a comprehensive and holistic view of the patient's needs, where the nurse is actively involved in all aspects of care delivery.

Correct Answer: C

Rationale: Methotrexate is a medication commonly used in the treatment of rheumatoid arthritis. It is known to have potential hepatotoxic effects, meaning it can harm the liver. Monitoring liver function tests (such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and bilirubin levels) is essential to detect any liver damage early on during methotrexate therapy. By closely monitoring liver function tests, healthcare providers can assess the medication's impact on the liver and determine if any dose adjustments or discontinuation of the drug is necessary to prevent further liver damage. Regular monitoring of liver function tests helps ensure the safe and effective use of methotrexate in patients with rheumatoid arthritis.

Correct Answer: B

Rationale: Possessing a body of knowledge is an important element that characterizes nursing as a profession. Nursing is a field that requires specialized education, training, and expertise in various areas of healthcare. Nurses are expected to have a comprehensive understanding of anatomy, physiology, pharmacology, and various nursing theories and practices to effectively care for patients. This body of knowledge distinguishes nursing as a profession and supports the delivery of high-quality, evidence-based patient care. While the other options (having members, being service-oriented, and a calling) are also important aspects of nursing, possessing a body of knowledge is fundamental to the profession's identity and practice.

Correct Answer: C

Rationale: The most effective intervention to prevent pressure ulcers in bedbound patients at risk, such as those with advanced dementia, is to use pressure-relieving support surfaces like specialized mattresses or cushions. These surfaces help distribute the pressure evenly, reducing the risk of pressure ulcer formation on bony prominences. Turning the patient every 2 hours (choice A) can also help relieve pressure, but it may not be sufficient to prevent pressure ulcers in high-risk individuals. Applying barrier creams or moisture barriers (choice B) can help protect the skin but may not address the underlying issue of pressure on vulnerable areas. Administering prophylactic antibiotics (choice D) is not recommended for preventing pressure ulcers as it does not address the root cause of the problem and can lead to antibiotic resistance. Therefore, the priority intervention should be to use pressure-relieving support surfaces to minimize the risk of pressure ulcers in
