A nurse is caring for a 6-week-old infant who has pyloric stenosis. Which of the following clinical manifestations should the nurse expect?

Choice A: A popping sensation when swallowing is not a sign of a tympanic membrane rupture, as it is a normal phenomenon that occurs when the eustachian tube opens and closes to equalize the pressure between the middle ear and the atmosphere. A popping sensation when swallowing may be associated with otitis media with effusion, which is a condition that causes fluid accumulation behind the eardrum, but it does not indicate a rupture.

Choice B: Green-blue discharge could be indicative of infection but is not as directly related to the rupture event as the sudden pain relief is.

Choice C: The correct answer is sudden relief of pain. This is because the rupture of the tympanic membrane releases the pressure and fluid that has built up in the middle ear, leading to an immediate decrease in pain.

Choice D: An increased temperature is not a sign of a tympanic membrane rupture, as it is a nonspecific symptom that may indicate various conditions, such as inflammation, infection, or fever. An increased temperature may be associated with otitis media with effusion, which is a condition that causes fluid accumulation behind the eardrum, but it does not indicate a rupture.

Choice A: This statement is correct, as a fracture of an epiphyseal plate, which is a cartilage layer at the end of a long bone where growth occurs, can impair the normal growth and development of the bone. Depending on the type and severity of the fracture, the epiphyseal plate may close prematurely, stop growing, or grow unevenly, resulting in deformity, shortening, or angular deviation of the affected limb.

Choice B: This statement is incorrect, as a fracture of an epiphyseal plate does not necessarily disrupt the blood supply to the bone unless there is also damage to the periosteum, which is a membrane that covers and nourishes

the bone. A disruption of the blood supply to the bone can cause avascular necrosis, which is a condition that causes bone death due to lack of oxygen and nutrients.

Choice C: This statement is incorrect, as a fracture of an epiphyseal plate does not cause bone marrow loss through the fracture unless there is damage to the medullary cavity, which is a hollow space within the bone that contains bone marrow. Bone marrow loss through the fracture can cause bleeding, infection, or anemia.

Choice D: This statement is incorrect, as a fracture of an epiphyseal plate does not take longer to heal in younger children than in older children. In fact, younger children tend to heal faster than older children due to their higher metabolic rate, greater blood supply, and more active growth factors. The healing time of a fracture depends on various factors, such as the type and location of the fracture, the treatment method, and the presence of complications.
