Hospital Medicine Indian Medical PG Question 1: Patients who need surgery within 24 hours are categorized under which color category in a disaster management triage?

• A. Green
• B. Yellow (Correct Answer)
• C. Blue
• D. Black

Hospital Medicine Explanation: ***Yellow*** - Patients in the **yellow category** are those who require **significant medical attention** and intervention, such as surgery, but whose condition is stable enough to withstand a delay of a few hours up to 24 hours without immediate threat to life or limb. - This category indicates a **delayed but urgent need** for treatment, distinguishing them from immediate (red) or minor (green) cases. *Blue* - The color **blue** is generally **not a standard triage category** in most commonly used disaster protocols (e.g., START, JumpSTART). - Triage systems typically use red, yellow, green, and black to prioritize patients based on immediate medical need and prognosis. *Green* - The **green category** is for patients with **minor injuries** who are considered "walking wounded" and can often wait for treatment for several hours, sometimes up to a few days. - These individuals are **stable** and do not require immediate intervention to preserve life or limb. *Black* - The **black category** is reserved for individuals who are **deceased** or have injuries so severe that survival is unlikely given the available resources, often implying **palliative care** rather than active life-saving interventions in a mass casualty event. - This category signifies that resources would be better allocated to patients with a higher chance of survival.

Hospital Medicine Indian Medical PG Question 2: Which of the following is not the component of qSOFA?

• A. Respiratory rate >22/min
• B. Altered mental status
• C. Unequally dilated pupils (Correct Answer)
• D. Systolic BP<100 mmHg

Hospital Medicine Explanation: ***Unequally dilated pupils*** - **Unequally dilated pupils** are not a component of the **qSOFA** score. This finding can be indicative of neurological issues such as increased **intracranial pressure** or **uncal herniation**, but not directly part of the sepsis screening tool [1]. - The qSOFA score focuses on easily obtainable clinical signs to rapidly identify patients at risk for poor outcomes from **sepsis**. *Respiratory rate >22/min* - A **respiratory rate greater than 22 breaths per minute** is one of the three criteria for the **qSOFA** score, indicating significant physiological stress. - This elevated respiratory rate suggests an increased work of breathing, often due to **metabolic acidosis** or **systemic inflammation** associated with sepsis. *Altered mental status* - **Altered mental status** (e.g., Glasgow Coma Scale score less than 15) is a core component of the **qSOFA** score [1]. - This sign reflects **cerebral hypoperfusion** or **encephalopathy** due to the systemic effects of sepsis [1]. *Systolic BP<100 mmHg* - A **systolic blood pressure less than 100 mmHg** is another key criterion of the **qSOFA** score. - This indicates **hypotension** and suggests inadequate tissue perfusion, a critical sign of **circulatory dysfunction** in sepsis [1].

Hospital Medicine Indian Medical PG Question 3: Best indicator to determine fluid required in hypovolemic patient is

• A. 2D echo
• B. CVP
• C. PCWP (Correct Answer)
• D. Intra arterial BP

Hospital Medicine Explanation: ***PCWP*** - **Pulmonary capillary wedge pressure (PCWP)** indirectly measures left atrial pressure, which reflects left ventricular end-diastolic pressure, a key indicator of **cardiac preload** and fluid status [1]. - A low PCWP in a hypovolemic patient suggests the need for **fluid resuscitation** to optimize cardiac output. *2D echo* - While 2D echocardiography can assess **cardiac function** and some parameters related to fluid status (like IVC collapsibility), it is not the most direct or specific indicator for fluid requirement in an acutely hypovolemic patient. - Its use often requires a skilled operator and is primarily diagnostic for structural and functional abnormalities rather than real-time fluid responsiveness guidance. *CVP* - **Central venous pressure (CVP)** reflects right atrial pressure, which is a measure of **right ventricular preload** [1]. - CVP can be misleading in patients with **right ventricular dysfunction** or **pulmonary hypertension**, making it less reliable for assessing overall fluid status compared to PCWP [1]. *Intra arterial BP* - **Intra-arterial blood pressure (BP)** is a direct and accurate measure of systemic arterial pressure, indicating **perfusion**. - While hypotension (low BP) is common in hypovolemia, BP alone does not reliably indicate the *amount* of fluid required or the patient's **fluid responsiveness**, as compensatory mechanisms can maintain BP even with significant volume loss.

Hospital Medicine Indian Medical PG Question 4: A surgeon is about to start a laparoscopic procedure on a patient. The floor nurse asks the surgeon about the identity of the patient, site of the procedure to be performed and any anticipated critical events during the surgery. These questions are a part of the

• A. nurses safety checklist
• B. WHO surgical safety checklist (Correct Answer)
• C. universal precautions checklist
• D. MCI patient safety checklist

Hospital Medicine Explanation: **WHO surgical safety checklist** - The questions about patient identity, procedure site, and anticipated critical events are key components of the **"Sign In"** and **"Time Out"** sections of the **WHO Surgical Safety Checklist**. - This checklist is designed to improve **patient safety** by ensuring communication and adherence to essential steps before, during, and after surgery, thereby reducing surgical errors. *nurses safety checklist* - While nurses play a crucial role in patient safety, there isn't a universally recognized "nurses safety checklist" that specifically encompasses these exact comprehensive surgical verification steps. - The comprehensive framework described, with its specific questions, aligns more closely with the broader, interdisciplinary **WHO Surgical Safety Checklist**. *universal precautions checklist* - **Universal precautions** focus on preventing the transmission of bloodborne pathogens and other infectious agents by treating all bodily fluids as potentially infectious. - This checklist primarily addresses **infection control** measures and does not cover patient identification, surgical site verification, or critical event anticipation. *MCI patient safety checklist* - A "MCI patient safety checklist" is not a widely recognized or standardized medical safety protocol. - The scenario describes a standard, internationally adopted set of safety checks specifically for surgical procedures, which is the **WHO Surgical Safety Checklist**.

Hospital Medicine Indian Medical PG Question 5: Which of the following are correct in respect of Systemic Inflammatory Response Syndrome (SIRS)? 1. It is caused by the release of lipopolysaccharide endotoxin from dying E. coli bacteria. 2. It is same as bacteraemia. 3. It results in Multiple Organ Dysfunction Syndrome (MODS). 4. White cell counts of more than 12 × 10^9/litre are present. Select the answer using the code given below.

• A. 2, 3 and 4
• B. 1, 2 and 3
• C. 1, 3 and 4 (Correct Answer)
• D. 1, 2 and 4

Hospital Medicine Explanation: ***1, 3 and 4*** - **SIRS** can be caused by the release of **lipopolysaccharide endotoxin** from the cell wall of dying **Gram-negative bacteria** like *E. coli*, triggering a systemic inflammatory response [1]. - One of the major complications of **SIRS** is the progression to **Multiple Organ Dysfunction Syndrome (MODS)**, where organs begin to fail due to uncontrolled inflammation [1]. - A component of the **SIRS criteria** is a white blood cell count greater than 12 x 10^9/L or less than 4 x 10^9/L, or the presence of more than 10% immature band forms [1]. *2, 3 and 4* - **Bacteremia** refers specifically to the presence of **viable bacteria** in the bloodstream, while **SIRS** is a broader inflammatory response that can be triggered by various causes (infectious or non-infectious). - While bacteremia can lead to SIRS, SIRS can also occur without bacteremia (e.g., pancreatitis, trauma). *1, 2 and 3* - **Bacteremia** is not the same as SIRS; bacteremia is a potential cause of SIRS, but SIRS can arise from non-infectious conditions as well. - The presence of bacteria in the blood (bacteremia) is a specific finding, whereas SIRS describes a *syndrome* of systemic inflammation. *1, 2 and 4* - This option incorrectly states that **SIRS is the same as bacteremia**, which it is not. - Also, while bacteremia can lead to SIRS, **MODS** is a crucial and often fatal consequence of advanced SIRS, which is omitted in this option.
