Correct Answer: A

Rationale: To obtain accurate cultures of urethral and bladder urine, the nurse should instruct the patient to collect the first 15 mL of urine in one container and the subsequent 50 mL in another. This method ensures that the specimens are separated appropriately for analysis. Choices B, C, and D are incorrect because collecting three early morning urine specimens, massaging the prostate, or collecting a routine urine specimen would not provide the specific separation of urethral and bladder urine required for this particular test.

Correct Answer: D

Rationale: Choice D is the correct answer because a swollen and thickened spermatic cord could indicate testicular torsion, which is a surgical emergency. Testicular torsion occurs when the spermatic cord twists, cutting off the blood supply to the testicle. This condition requires immediate intervention to prevent testicular damage. Choices A, B, and C do not present findings that suggest a surgical emergency requiring immediate intervention.

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.

Correct Answer: A

Rationale: The best way to manage a patient's intake of dietary fiber is to increase it gradually. This approach helps prevent gastrointestinal discomfort that may arise from a sudden increase in fiber intake. Choice B is incorrect because increasing intake suddenly can lead to digestive issues. Choice C is incorrect as decreasing fiber intake abruptly may not be necessary and can impact overall health. Choice D is incorrect as maintaining a high intake without considering the patient's current intake level 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.
