Correct Answer: A

Rationale: The correct way to manage a patient's intake of dietary fiber is to increase it gradually. This approach helps prevent gastrointestinal discomfort that can occur when fiber intake is suddenly increased. Choice B is incorrect because sudden increases in fiber intake can lead to bloating, gas, and other digestive issues. Choice C is incorrect as decreasing fiber intake abruptly can disrupt bowel regularity and cause constipation. Choice D is incorrect because maintaining a high intake of fiber without considering the patient's current levels can also cause digestive problems.

Correct Answer: C

Rationale: The correct question for the nurse to ask the mother before administering the MMR vaccine to a 15-month-old is about the child's allergy to antibiotics. This is crucial because the MMR vaccine contains neomycin, an antibiotic, and being allergic to antibiotics like neomycin is a contraindication for the MMR vaccine. Asking about sore throats, eating habits, or exposure to infections is not directly relevant to the administration of the MMR vaccine.

Correct Answer: D

Rationale: The correct answer is D. Under the health services support area concept, the medical care under the MEDCOM is divided into eight geographical areas of responsibility designated as health services support regions, each of which is further subdivided into two or more health service areas. This structure allows for a more organized and efficient delivery of medical care across different regions. Choices A, B, and C are incorrect because they do not accurately describe how medical care under the MEDCOM is divided according to the concept of health services support areas.

Correct Answer: A

Rationale: Nurses typically collect blood specimens from patients as part of their everyday duties in medical settings. They are trained in venipuncture techniques and are responsible for ensuring that blood samples are properly obtained and labeled for diagnostic testing. Medical technologists process and analyze the blood specimens in the laboratory under the direction of a physician, but the actual collection of specimens is commonly performed by nurses. Physicians are primarily responsible for diagnosing and treating medical conditions rather than collecting blood specimens. Pharmacists are healthcare professionals who specialize in medication management and dispensing, not in collecting blood specimens.

Correct Answer: D

Rationale: The correct answer is D because all the situations listed reflect aspects of client advocacy. Pulling the curtain around the client's bed while changing a dressing ensures privacy and dignity for the client, which is an essential part of advocacy. Contacting the health care provider to request a meeting for the client involves advocating for the client's needs and preferences. Ensuring access to medical information by appropriate personnel only is another way the nurse advocates for the client by safeguarding their confidentiality and promoting proper communication. Choices A, B, and C all demonstrate different aspects of advocacy, making option D the correct choice.
