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: B

Rationale: The Patient Holding Squad is the module that is composed of practical nurses, medical specialists, and equipment to provide medical support for minimal care patients. This squad focuses on providing necessary care for patients who require minimal attention. Choices A, C, and D are incorrect because they do not specifically cater to the needs of minimal care patients. The Treatment Squad may involve more intensive procedures, the Area Support Squad focuses on broader support functions, and the Surgical Squad is specialized for surgical interventions.

Correct Answer: D

Rationale: A swollen and thickened spermatic cord could indicate testicular torsion, which is a surgical emergency.

Correct Answer: B

Rationale: The correct answer is B. Pain management is essential before the procedure to ensure the client's comfort and cooperation during the dressing change. Escorting the client to the physical therapy department (choice A) is not the priority at this time. While obtaining sterile dressing supplies (choice C) is important, ensuring pain management takes precedence. Assisting the client to the bathroom (choice D) is not directly related to the priority intervention of pain management before the whirlpool treatment.

Correct Answer: C

Rationale: The correct question the nurse should ask the mother before administering an MMR vaccine to a 15-month-old is whether the child is allergic to any antibiotics. This is crucial because vaccines like MMR contain components that the child could be allergic to, such as neomycin. Checking for antibiotic allergies is essential to prevent adverse reactions to the vaccine. The other options are less relevant in this context. Asking about sore throats, eating habits, or exposure to infections does not directly impact the administration of the MMR vaccine.
