Question 1

Which one of the following is a benzodiazepine reversal medication for an overly sedated patient?

Accepted Answer

romazicon (Flumazenil)

Answer

Flumazenil (Romazicon) is a specific benzodiazepine receptor antagonist used to reverse the sedative effects of benzodiazepines. It competes with benzodiazepines for binding sites on GABA-A receptors in the brain, rapidly counteracting central nervous system depression. In contrast, Naloxone is used to reverse opioid overdose.

Question 2

Which of the following symptoms, after an esophagoscopy to obtain a biopsy of the thoracic esophagus, MOST suggests the need for urgent management of perforation?

Accepted Answer

Chest pain, dysphagia, and tachycardia

Answer

Perforation of the esophagus is a serious complication of esophagoscopy, and symptoms like severe chest pain, difficulty swallowing (dysphagia), and an elevated heart rate (tachycardia) are classic signs. These symptoms indicate potential mediastinitis or leakage of contents into the chest cavity, requiring immediate medical intervention. A mild cough and sore throat are common, less severe post-procedure symptoms.

Question 3

How soon after the collection should the laboratory get the duodenal aspirate?

Accepted Answer

Immediately

Answer

Duodenal aspirate samples, especially when testing for parasites like Giardia or bacterial overgrowth, need to be processed immediately to ensure the viability of organisms and prevent degradation of diagnostic markers. Delays can lead to inaccurate results, as some organisms are fragile or their numbers may decrease rapidly outside the body. Prompt delivery to the lab maintains sample integrity for accurate diagnosis.

Question 4

Which of the following phases should pain control be started at, according to the WHO's three-step ladder approach to pain management, if a patient's abdominal discomfort is related to colon cancer and ranges from 4 to 8 on the pain scale?

Accepted Answer

Whichever step is appropriate at the time of initiation

Answer

The WHO analgesic ladder is designed to match the intensity of pain with the appropriate level of analgesic. For moderate to severe pain (4-8 on a scale of 0-10), it is appropriate to start at Step 2 (weak opioid + non-opioid) or Step 3 (strong opioid + non-opioid), rather than strictly progressing through each step sequentially. The principle is to provide effective pain relief promptly, escalating or de-escalating as needed, based on the initial pain level.

Question 5

Ten individuals were affected by a 2-week-long epidemic of Clostridium difficile infections in the gastroenterology unit. Which of the following should staff members focus their efforts on in order to stop the spread of the infection?

Accepted Answer

Contact precautions/hand hygiene

Answer

Clostridium difficile (C. diff) is highly contagious and spread through the fecal-oral route, often via contaminated surfaces and healthcare workers' hands. Implementing strict contact precautions, including gown and glove use, and meticulous hand hygiene with soap and water are the most critical interventions to prevent its spread in a healthcare setting. These measures directly interrupt the transmission chain during an outbreak.
