In Crohn's disease, true improvement is shown by relief of symptoms and better nutritional status as inflammation eases. If a patient still experiences significant pain that requires the maximum safe dose of acetaminophen for several days, that signals persistent symptoms despite treatment, suggesting the disease is not yet under control and therapy may need to be reassessed. The other signs—pain decreasing over 24 hours, normal weight gain, and stable appetite—all point toward improving disease activity. So needing the maximum daily acetaminophen dose for three days indicates the condition is not improving.

In the inflammatory phase, the body acts to stop bleeding and begin cleanup. Platelets are key for hemostasis: they adhere to exposed vessels and form a plug, releasing factors that start the coagulation cascade to seal the wound. Neutrophils are the main early immune cells that arrive to the site and perform debris and bacteria clearance through phagocytosis. This combination—platelets driving clot formation and neutrophils handling debris cleanup—best captures the primary actions of this phase. Other cells listed have roles later in healing: fibroblasts and keratinocytes contribute to tissue rebuilding, endothelial and smooth muscle cells are involved in new vessel formation, and macrophages arrive after neutrophils to continue cleanup and signaling.

In end-of-life care, the goal is comfort, and Do Not Resuscitate is specifically about not performing CPR, not about withholding relief from distress. If a sedative has been prescribed to relieve anxiety and dyspnea, it should be given as ordered to promote a peaceful and comfortable process for the patient. Administering the prescribed sedative aligns with the primary duty of care at this stage: alleviate suffering and support the patient’s comfort. After giving the medication, the nurse should monitor the patient for relief of symptoms and any signs of over-sedation or adverse effects, and document the response and any changes in condition. If symptoms persist or worsen, notify the physician promptly to adjust the plan. Why the other options aren’t appropriate: not giving sedation because of the DNR status neglects comfort measures; withholding the sedative and waiting for a physician’s call delays relief; giving only half the dose disregards the prescribed order and could fail to achieve symptom relief.

Increased intracranial pressure tends to produce signals that reflect pressure on brain structures and impaired cerebral perfusion. The classic signs include a headache from stretched meninges, vomiting from pressure affecting the brain’s vomiting center, and changes in mental status as cerebral function becomes compromised. Pupil reactivity can be altered because higher pressure can compress the oculomotor nerve, leading to sluggish or unequal pupils. Papilledema, swelling of the optic disc seen on exam, occurs when sustained high pressure transmits along the optic nerve sheath. These findings help distinguish ICP elevation from other problems that cause similar symptoms in different body systems. Fever and neck stiffness point more toward meningitis or meningeal irritation. Chest pain with dyspnea suggests a cardiac or pulmonary issue. Abdominal pain radiating to the back points to abdominal or vascular etiologies.
