Correct Answer: D

Rationale: The correct answer is D, Combat lifesaver. A Combat Lifesaver is a nonmedical member of a unit who receives specialized training in advanced first aid procedures, beyond basic first aid care. This training equips them to provide crucial medical assistance in emergency situations where immediate medical personnel may not be available. Choices A, B, and C are incorrect as they do not specifically refer to nonmedical members trained in advanced first aid care beyond basic procedures.

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: C

Rationale: The correct answer is C: The adrenal medulla. Norepinephrine is secreted by the adrenal medulla and is involved in the body's 'fight or flight' response. The pancreas (choice A) secretes insulin and glucagon, not norepinephrine. The adrenal cortex (choice B) secretes hormones like cortisol and aldosterone, but not norepinephrine. The anterior pituitary gland (choice D) secretes various hormones like growth hormone and thyroid-stimulating hormone, but not norepinephrine.

Correct Answer: B

Rationale: The correct answer is B: Diverticulitis. Diverticulitis specifically refers to the infection or inflammation of diverticula in the colon. Choice A, Diverticulosis, is incorrect as it refers to the condition of having diverticula without inflammation or infection. Choices C and D, Cholelithiasis and Cholecystitis, are unrelated conditions affecting the gallbladder, not the colon.

Correct Answer: D

Rationale: The correct answer is D because implementing Level II through Level IV CSH operations is not a major duty of the M6 practical nurse. A practical nurse's major duties include performing preventive, therapeutic, and emergency nursing care procedures (Choice A), managing other paraprofessional personnel (Choice B), and managing ward or unit operations (Choice C). These duties are more aligned with the responsibilities of a practical nurse, emphasizing patient care and coordination within a healthcare setting.
