Rapid Response and Code Management Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Rapid Response and Code Management. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Rapid Response and Code Management Indian Medical PG Question 1: In case of disaster, which color code is used for patients requiring immediate care?
- A. Black
- B. Yellow
- C. Red (Correct Answer)
- D. Green
Rapid Response and Code Management Explanation: ***Red***
- The **red tag** is used for patients with **immediate life-threatening injuries** who have a high probability of survival with prompt medical intervention.
- These patients require urgent attention and transportation to a medical facility.
*Black*
- The **black tag** is reserved for patients who are either **deceased** or have injuries so severe that survival is unlikely, making them suitable for palliative care only.
- This category indicates that critical resources should not be expended on these individuals when others have a higher chance of survival.
*Yellow*
- The **yellow tag** is assigned to patients whose injuries are **significant but not immediately life-threatening**, and who can wait for a few hours without immediate danger.
- These patients are often observed for potential deterioration but do not require immediate surgical or intensive interventions.
*Green*
- The **green tag** signifies patients with **minor injuries** that are not serious and do not require immediate medical attention.
- These individuals are often referred to as "walking wounded" and can typically wait for extended periods for care without risk to life or limb.
Rapid Response and Code Management Indian Medical PG Question 2: Which of the following is NOT included in the resuscitation of a neonate with HR < 60/min?
- A. Endotracheal tube intubation
- B. Chest compression
- C. Adrenaline
- D. None of the above (Correct Answer)
Rapid Response and Code Management Explanation: ***None of the above***
- All listed interventions—**endotracheal tube intubation**, **chest compressions**, and **adrenaline administration**—are standard components of neonatal resuscitation when the heart rate remains below 60 beats/min despite initial steps.
- This question asks which is *NOT* included, implying that all options are, in fact, appropriate interventions in this critical scenario.
*Endotracheal tube intubation*
- This is a critical step in **securing the airway** and ensuring effective positive pressure ventilation when other methods fail or prolonged mechanical ventilation is anticipated.
- It's indicated if the heart rate remains below 60 bpm despite adequate bag-mask ventilation and chest compressions.
*Chest compression*
- **Chest compressions** are initiated when the heart rate is less than 60 bpm *after* 30 seconds of effective positive pressure ventilation.
- They are used in conjunction with positive pressure ventilation to improve cardiac output and myocardial perfusion.
*Adrenaline*
- **Adrenaline** is administered if the heart rate remains below 60 bpm *despite* adequate ventilation and chest compressions.
- It acts as a potent **vasopressor** and **cardiac stimulant**, increasing heart rate and contractility.
Rapid Response and Code Management Indian Medical PG Question 3: In CPR, number of chest compressions per minute in an adult:
- A. 30-50 per minute
- B. 100-120 per minute (Correct Answer)
- C. 50-72 per minute
- D. 120-200 per minute
Rapid Response and Code Management Explanation: ***100-120 per minute***
- The **American Heart Association (AHA)** and other international resuscitation guidelines recommend a compression rate of **100 to 120 beats per minute** for adults.
- This rate ensures adequate blood flow to vital organs while minimizing rescuer fatigue.
*30-50 per minute*
- This rate is **too low** and would be ineffective in maintaining adequate cerebral and coronary perfusion during cardiac arrest.
- Insufficient compressions per minute significantly **reduce the chances of survival** and positive neurological outcomes.
*50-72 per minute*
- While better than 30-50, this rate is still **below the recommended range** for effective CPR in adults.
- It would likely result in **inadequate blood flow** to the brain and heart, diminishing the effectiveness of resuscitation.
*120-200 per minute*
- While aiming for higher compression rates might seem beneficial, rates **above 120 per minute** can be counterproductive.
- Excessively fast compressions can **reduce chest recoil** and ventricular filling time, actually decreasing cardiac output and perfusion.
Rapid Response and Code Management Indian Medical PG Question 4: According to current CPR guidelines, the immediate first action when encountering an unresponsive patient should be:
- A. Intracardiac atropine
- B. Hysterectomy
- C. Airway maintenance (Correct Answer)
- D. IV adrenaline
Rapid Response and Code Management Explanation: ***Airway maintenance***
- **Airway maintenance** is the immediate priority in an unresponsive patient to ensure adequate oxygenation and ventilation [1].
- Establishing an open airway (e.g., head tilt-chin lift or jaw thrust) is crucial before assessing breathing or circulation [1].
*Intracardiac atropine*
- **Intracardiac atropine** is not a recommended intervention in modern CPR guidelines and carries significant risks with no proven benefit.
- Atropine is typically used intravenously for symptomatic **bradycardia**, not as a first-line agent for unresponsive patients in cardiac arrest.
*Hysterectomy*
- **Hysterectomy** is a surgical procedure to remove the uterus and is completely irrelevant to the immediate management of an unresponsive patient.
- This option is medically absurd and demonstrates a clear misunderstanding of emergency medical care.
*IV adrenaline*
- **Intravenous (IV) adrenaline** is a crucial drug in cardiac arrest, but it is typically administered *after* establishing an airway, initiating chest compressions, and assessing the cardiac rhythm.
- It is not the *immediate first action* upon encountering an unresponsive patient, as securing the airway precedes drug administration [1].
Rapid Response and Code Management Indian Medical PG Question 5: When resuscitating a patient in shock which of the following is not an adequate parameter to predict end point of resuscitation?
- A. Mixed venous oxygen saturation
- B. Base deficit
- C. Lactate
- D. Blood pressure (Correct Answer)
Rapid Response and Code Management Explanation: ***Blood pressure***
- While essential for initial assessment and guiding treatment, **blood pressure** can be maintained within normal limits even in significant shock states due to compensatory mechanisms [1].
- Blood pressure alone does not reflect **tissue perfusion** or cellular oxygenation, which are the true endpoints of resuscitation [1].
*Mixed venous oxygen saturation*
- **Mixed venous oxygen saturation (SvO2)** reflects the balance between oxygen delivery and consumption, providing insight into global tissue oxygenation.
- A low SvO2 indicates inadequate oxygen delivery relative to demand, making it a valuable target for guiding resuscitation.
*Base deficit*
- **Base deficit** is a measure of metabolic acidosis and reflects the severity of tissue hypoperfusion and anaerobic metabolism.
- Normalization of base deficit indicates correction of metabolic derangements and improved tissue perfusion.
*Lactate*
- **Lactate** is a product of anaerobic metabolism, which occurs when tissues are not adequately perfused or oxygenated.
- Elevated lactate levels indicate tissue hypoperfusion, and serial measurements are crucial for monitoring the effectiveness of resuscitation and predicting outcomes.
Rapid Response and Code Management Indian Medical PG Question 6: As per the recent guidelines of resuscitation, what should be done if asystole is not responding to two consecutive doses of epinephrine?
- A. Administer another dose of epinephrine.
- B. Continue high-quality CPR and consider advanced airway management. (Correct Answer)
- C. Administer vasopressin as a second-line drug.
- D. Defibrillation with 200J.
Rapid Response and Code Management Explanation: ***Continue high-quality CPR and consider advanced airway management.***
- For **asystole** that is unresponsive to initial epinephrine doses, maintaining **high-quality CPR** is the cornerstone of resuscitation efforts, ensuring vital organ perfusion.
- **Advanced airway management** (e.g., endotracheal intubation) should be considered early to secure the airway and facilitate ventilation, optimizing oxygen delivery during CPR.
*Administer another dose of epinephrine.*
- While epinephrine is the primary drug for asystole, repeating doses beyond the initial recommended schedule without other interventions is not indicated if there is no response, as it may not improve outcomes.
- The focus shifts to identifying and treating reversible causes while maintaining high-quality CPR, rather than escalating epinephrine frequency.
*Administer vasopressin as a second-line drug.*
- **Vasopressin** is no longer recommended in adult cardiac arrest resuscitation algorithms, including for asystole, according to current guidelines from organizations like the American Heart Association.
- Its use has not been shown to improve survival to hospital discharge or neurological outcomes compared to epinephrine.
*Defibrillation with 200J.*
- **Defibrillation** is only indicated for shockable rhythms such as **ventricular fibrillation (VF)** or **pulseless ventricular tachycardia (pVT)**.
- Asystole is a **non-shockable rhythm**, meaning there is no electrical activity to defibrillate, and administering a shock is ineffective and can be harmful.
Rapid Response and Code Management Indian Medical PG Question 7: In ACLS, which antiarrhythmic drug can be given following ventricular fibrillation after cardiac arrest other than epinephrine?
- A. Amiodarone (Correct Answer)
- B. Dopamine
- C. Adenosine
- D. Atropine
Rapid Response and Code Management Explanation: ***Amiodarone***
- **Amiodarone** is a Class III antiarrhythmic agent recommended in ACLS for **refractory ventricular fibrillation (VF)** or pulseless ventricular tachycardia (pVT) after initial defibrillation and epinephrine.
- It works by blocking potassium channels, prolonging repolarization, and increasing the **refractory period** in the heart.
*Dopamine*
- **Dopamine** is a **vasopressor** used to improve **hemodynamics** in patients with symptomatic hypotension, not primarily as an antiarrhythmic for VF.
- Its effects include increasing heart rate, myocardial contractility, and blood pressure.
*Adenosine*
- **Adenosine** is a drug of choice for **supraventricular tachycardia (SVT)** to interrupt reentry pathways in the AV node.
- It is not indicated for ventricular fibrillation, as it would be ineffective in this rhythm.
*Atropine*
- **Atropine** is an **anticholinergic agent** used to treat **symptomatic bradycardia** by increasing heart rate.
- It has no role in the management of ventricular fibrillation.
Rapid Response and Code Management Indian Medical PG Question 8: Which of the following cannula is used in patient with severe dehydration and diarrhea?
- A. Pink
- B. Grey (Correct Answer)
- C. Green
- D. Blue
Rapid Response and Code Management Explanation: A **16-gauge (Grey)** cannula allows for a high flow rate, making it ideal for rapid fluid resuscitation in severely dehydrated patients [1]. This size is crucial for quickly restoring intravascular volume in cases of severe dehydration and diarrhea where large amounts of fluid are lost. [2]
A **20-gauge (Pink)** cannula offers a moderate flow rate, suitable for routine intravenous fluid administration or medication delivery, but generally too slow for rapid resuscitation in severe dehydration.
An **18-gauge (Green)** cannula provides a good flow rate, making it suitable for blood transfusions or moderate fluid resuscitation.
A **22-gauge (Blue)** cannula has a slow flow rate, typically used for pediatric patients, elderly patients with fragile veins, or for maintaining venous access for medication administration.
Rapid Response and Code Management Indian Medical PG Question 9: A child was diagnosed as a case of pauci-immune crescentic glomerulonephritis. The treatment to be given in this child is –
- A. Immunoglobulins
- B. Cyclophosphamide
- C. Methylprednisolone
- D. Prednisolone + Cyclophosphamide (Correct Answer)
Rapid Response and Code Management Explanation: ***Prednisolone + Cyclophosphamide***
- **Pauci-immune crescentic glomerulonephritis** (also known as ANCA-associated vasculitis) is a rapidly progressive and severe autoimmune condition affecting the kidneys.
- **Combination therapy** with a corticosteroid (like prednisolone) and an immunosuppressant (like cyclophosphamide) is the standard and most effective initial treatment to control inflammation and suppress the immune response.
*Immunoglobulins*
- **Intravenous immunoglobulins (IVIG)** are sometimes used in autoimmune diseases, but they are not the first-line treatment for pauci-immune crescentic glomerulonephritis due to its aggressive nature.
- IVIG might be considered as an **adjunctive therapy** or in specific cases of refractory disease, but not as monotherapy.
*Cyclophosphamide*
- While **cyclophosphamide** is a critical component of treatment for **pauci-immune crescentic glomerulonephritis** due to its potent immunosuppressive effects, it is not used alone.
- It is typically combined with a **corticosteroid** (such as prednisolone) to achieve a more rapid and comprehensive anti-inflammatory and immunosuppressive effect.
*Methylprednisolone*
- **Methylprednisolone** (a corticosteroid) is routinely used in the initial management of **pauci-immune crescentic glomerulonephritis** to rapidly reduce inflammation.
- However, it is generally part of a **combination regimen** and is not sufficient as monotherapy for inducing remission in this severe form of glomerulonephritis.
Rapid Response and Code Management Indian Medical PG Question 10: Rapid polymerization with high intensity light will:
- A. No effect on bond strength
- B. Initial increase followed by a decrease in bond strength
- C. Decrease bond strength by increasing stresses (Correct Answer)
- D. Increase bond strength by decreasing stresses
Rapid Response and Code Management Explanation: ***Decrease bond strength by increasing stresses***
- Rapid polymerization with **high-intensity light** leads to a **faster gel point conversion** and a rapid increase in viscosity.
- This rapid setting traps internal stresses within the **polymerized material** due to **volumetric shrinkage**, preventing proper stress relief and leading to higher internal stresses, which ultimately **reduces bond strength**.
*Increase bond strength by decreasing stresses*
- This statement is incorrect because rapid polymerization during high-intensity light curing causes a rapid increase in **polymerization shrinkage stress**.
- **Increased stresses** within the material will tend to **reduce bond strength**, not increase it, as the material is less able to relax these stresses.
*No effect on bond strength*
- This is incorrect as the **rate of polymerization** directly influences the development of **stress** within the composite material.
- **High-intensity light curing** affects the **kinetics of polymerization**, leading to significant changes in **mechanical properties** like bond strength.
*Initial increase followed by a decrease in bond strength*
- While there is an initial increase in **mechanical properties** as the material polymerizes, the **high stress levels** generated by rapid polymerization with high intensity light cause a net decrease in the **ultimate bond strength**.
- The rapid formation of a **cross-linked network** under high intensity light creates a stiff material that cannot effectively relieve internal stresses, leading to **weakened bonds**.
