Which of the following is associated with increased risk for primary polydipsia?

Which of the following are NOT associated with myocarditis?

In this scenario a 50-year-old male is brought in from the bus station where he was found sleeping on a covered park bench during a severe winter storm. He arrives obtunded with limited history, severely hypothermic (core temperature of 26°C or 78.8°F) and bradycardic in slow atrial fibrillation. The patient decompensates and suffers a v-fib arrest, requires volume resuscitation, active rewarming in addition to typical ACLS measures. If such measures are taken, then the patient will have return of spontaneous circulation, at which point the team will have the opportunity to contact either their institution’s cardiopulmonary bypass personnel or contact the nearest center with this capability.

Meta-analyses of symptom-focused medication management suggest that impulsive and behavioral dysregulation in borderline personality disorder (BPD) is best treated by which of the following classes of psychotropics?

In the aftermath of a tornado, a 35-year-old man with a history of recurrent deep vein thromboses, on Eliquis for anticoagulation, suffers a severe chain saw injury while clearing debris. The chain saw strikes his left midthigh, causing substantial hemorrhage and limb-threatening trauma. Despite prompt EMS intervention, including tourniquet application, IV fluid resuscitation, and pain management, the patient arrives at a rural emergency department in critical condition with hypotension, tachycardia, and significant pain. The nearest surgical facility is an hour away, and helicopter transport is not feasible due to weather conditions. In the emergency department, the trauma team must navigate the complexities of resuscitation, including the challenges of reversing anticoagulation, administering uncrossmatched blood, and managing the time-sensitive issue of tourniquet removal.

This case presents a medical scenario involving a 55-year-old woman in critical condition after a suspected bioterrorism attack involving pneumonic plague. The patient arrives at the emergency department intubated and in septic shock, with a history of severe respiratory distress, high fever, and coughing up blood. EMS reports possible exposure to a plague bioterrorism attack in a subway, raising concerns about the patient’s condition and potential public health risks. The case focuses on recognizing bioterrorism-related illnesses, using appropriate personal protective equipment (PPE), and isolating the patient. Key management steps include advanced airway management, fluid resuscitation, vasopressor support, and initiating appropriate antibiotics for pneumonic plague. The scenario also highlights the need for coordination with infection control, notification of public health authorities, and postexposure prophylaxis for healthcare providers exposed to the patient’s secretions. This exercise emphasizes quick, coordinated care in the face of a potential biological disaster involving a highly contagious pathogen.

A comprehensive classification system for the ultrasound diagnosis of early pregnancy is essential. Such a classification system must provide clear decriptions and diagnostic criteria for all possible pregnancy locations. The use of uniform terminology will also aid to reduce the risk of misdiagnosis and inappropriate treatment.

This scenario focuses on a 42-year-old male who was involved in a rollover motor vehicle accident while evacuating from a wildfire. The patient presents with an open tib-fib fracture, signs of smoke inhalation injury, and abdominal tenderness suggestive of internal trauma. The learner must manage a combination of traumatic injuries, including a liver laceration and impending airway compromise due to smoke inhalation. The scenario highlights key principles in disaster medicine, such as the importance of early airway management, trauma stabilization, and understanding the complications arising from evacuation during wildfires. Participants must prioritize advanced trauma care, administer appropriate antibiotics and tetanus for open fractures, and manage the patient’s shock through fluid resuscitation and blood products. The case also emphasizes the risks of delayed evacuation during wildfires and the need for careful clinical assessment in mass-casualty settings.

What is the gold standard for treating impulsive aggression?

A severe winter storm has caused widespread power outages in the area. Temperatures are in the 20s Fahrenheit. To power their multifamily home, a group of families has set up a gasoline-powered generator in the basement, which has been running overnight. This has caused elevated carbon monoxide (CO) levels in the home as the CO has permeated the drywall and reached every part of the home. Multiple members of the families have begun feeling ill. One of them, a 75-year-old grandfather with multiple medical problems, is confused, lethargic, and cannot walk. He has a carboxyhemoglobin level of 30%, ischemic changes on his ECG, and an elevated troponin. If high-flow oxygen is not applied, the patient will have unstable ventricular tachycardia requiring synchronized cardioversion. He will stabilize with appropriate therapy. Family members will complain of symptoms, and this should prompt their evaluation or referral to be evaluated. If this does not happen, one of them will collapse on the floor.

Which of the following classes of medication should not be considered for long-term adjunct therapy for treatment-resistant schizophrenia (TRS)?

This case study examines the management of a dog bite injury in a flood-prone coastal region following a Category 5 hurricane. The scenario involves a 58-year-old male with hypertension and type 2 diabetes who was bitten by a large dog while attempting a rescue operation. The patient presents with multiple deep lacerations and puncture wounds on his right forearm, significant pain, and swelling. The case highlights the critical steps in evaluating and managing bite wounds in a disaster setting, including scene safety, situational awareness, personal protective equipment (PPE), wound irrigation, decontamination, dressing, and splinting. Emphasis is placed on the importance of communication and teamwork among the rescue team, coordination with animal control, and effective communication with receiving medical facilities. The scenario also addresses the need for advanced management, including imaging, antibiotics, and postexposure prophylaxis for tetanus and rabies. This study serves as an educational tool for medical professionals in emergency medicine and disaster response, providing insights into the complexities of managing animal bite injuries in challenging environments.

Congenital uterine anomalies arise from an abnormality in the embryological development process. There can be defects in unification, canalisation or complete agenesis. Uterine anomalies are mnore common in those who experience miscaarriage compared with the general population. Patients with uterine anomalies are at higher risk of infertility, early and second trimester miscarriage, pre-term birth and malpresenatation at delivery.
