When applying an AED, you want the pads to stick firmly and deliver the shock effectively. If the chest is wet, water can prevent full contact between the pads and the skin and can even alter how the current travels, increasing the risk of burns or an ineffective shock. Drying the chest before placing the pads ensures good pad adhesion and proper conduction of the defibrillation energy. So, if the chest is wet, you should dry it before attaching the AED pads. The other options don’t fit this specific step: you wouldn’t wait with CPR for 30 seconds before applying the pads, and medical control isn’t needed for this immediate preparation. The key action is to dry the chest if it is wet.

The key idea is that epinephrine for anaphylaxis is a first-line, time-critical treatment in EMS, and the intramuscular route is preferred in the field. Injecting epinephrine into the thigh provides rapid, reliable absorption with a safer profile than IV administration in prehospital care. This rapid action helps reduce airway swelling, counteracts bronchospasm, and supports blood pressure, which is crucial as symptoms can escalate quickly. In practice, epinephrine is given intramuscularly, typically as a single dose for adults and children (0.3 mg adult, 0.15 mg pediatric) into the mid-outer thigh, with the option to repeat every 5–15 minutes if symptoms persist. Because of the urgency, EMS teams generally administer it without waiting for medical control, since delays can worsen outcomes. IV epinephrine is not the norm in the field due to higher risk of adverse effects like arrhythmias and severe hypertension; it’s reserved for controlled, hospital-based settings with close monitoring and dosing under supervision. It’s not a last-resort measure either—prompt IM epinephrine is what often halts progression and stabilizes the patient enough to transport. After administration, continue airway support, high-flow oxygen, monitor vital signs, establish IV access, and transport to an appropriate facility.

The main idea is the different goals of palliative care versus curative treatment. Palliative care centers on comfort, symptom relief, and quality of life, and it can be provided alongside treatments aimed at curing or controlling the disease. Curative treatment, on the other hand, is about eliminating the disease or achieving a cure, even if that involves aggressive interventions. So the true statement reflects this distinction: palliative care focuses on comfort and quality of life, while curative treatment aims to eliminate the disease. It’s important to note that palliative care isn’t only for those who are terminal, and it isn’t about experimental therapies; it’s about reducing suffering and supporting patients and families, often in conjunction with disease-directed therapy.

Delirium tremens occurs during severe alcohol withdrawal and features delirium with autonomic hyperactivity, including sweating and disorientation, often accompanied by visual hallucinations. This typically appears a day or two after the last drink in someone with heavy, prolonged alcohol use. The combination of confusion, sweating, and visual hallucinations in a heavy drinker points most strongly to delirium tremens rather than intoxication (which would not usually include delirium and persistent autonomic instability), hypovolemia (which centers on dehydration and low blood pressure without prominent hallucinations), or a primary psychiatric illness like schizophrenia (which isn’t tied to recent alcohol use or withdrawal in this context).
