Post-Anesthesia Care Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Post-Anesthesia Care. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Post-Anesthesia Care Indian Medical PG Question 1: The Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) for rating postoperative pain in children under one year excludes all of the following, EXCEPT:
- A. Oxygen saturation
- B. Torso
- C. Verbal response (Correct Answer)
- D. Cry
Post-Anesthesia Care Explanation: ***Verbal response***
- The Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) is designed for children **under one year of age**, who are typically pre-verbal.
- While verbal complaints are not assessed, a child's **verbal response** (e.g., moaning, crying, or not making sounds at all) in relation to pain is a component of the scale, contributing to the interpretation of their comfort level.
*Oxygen saturation*
- **Physiological parameters** like oxygen saturation are typically not part of behavioral pain scales like CHEOPS, which focus on observable behaviors.
- While low oxygen saturation can indicate distress, it is not a direct measure of pain for this scale.
*Torso*
- The CHEOPS scale assesses **pain-related behaviors** of extremities (e.g., legs, arms) and facial expressions, but does not specifically include observations of the "torso" as a separate category.
- Behaviors like stiffening or arching of the torso might be implicitly considered under overall body tension, but it’s not a distinct domain.
*Cry*
- The **quality and intensity of crying** is a primary behavioral indicator of pain in pre-verbal infants and is a significant component of many pediatric pain scales, including CHEOPS.
- A child's cry, along with other behaviors, helps differentiate between various levels of discomfort or pain.
Post-Anesthesia Care Indian Medical PG Question 2: A postoperative patient with pH 7.25, MAP (mean arterial pressure) 60 mm Hg is treated with?
- A. Only normal saline
- B. fluid restriction
- C. Fluid therapy with CVP monitoring (Correct Answer)
- D. I.V. sodium bicarbonate
Post-Anesthesia Care Explanation: ***Fluid therapy with CVP monitoring***
- The patient's **MAP of 60 mmHg** indicates **hypotension** and potential **hypovolemic shock**, while pH 7.25 suggests **acidosis**, which could be metabolic due to poor perfusion. Initial treatment should focus on **restoring circulating volume** to improve blood pressure and organ perfusion.
- **Central venous pressure (CVP) monitoring** is crucial to guide fluid resuscitation. It helps assess the patient's fluid status and ensures that enough fluid is given to improve cardiac output without causing fluid overload, especially in a severely ill patient.
*Only normal saline*
- While normal saline is used for fluid resuscitation, simply stating "only normal saline" is insufficient because it doesn't address the **critical need for monitoring** to guide treatment.
- The amount and rate of fluid administration need to be carefully controlled based on the patient's response and hemodynamic parameters.
*Fluid restriction*
- **Fluid restriction** would be contraindicated in this patient because the **low MAP** suggests **hypovolemia or cardiogenic shock**, requiring fluid repletion, not restriction.
- Restricting fluids could further worsen hypotension and organ hypoperfusion, leading to increased acidosis and organ damage.
*I.V. sodium bicarbonate*
- Administering **I.V. sodium bicarbonate** to correct acidosis without addressing the underlying cause of hypotension and poor perfusion is generally not recommended.
- The acidosis (pH 7.25) is likely due to **poor tissue oxygenation and lactic acid production** from inadequate blood flow; correcting this with fluids will resolve the acidosis.
Post-Anesthesia Care Indian Medical PG Question 3: All of the following are complications of epidural anaesthesia, EXCEPT:
- A. Urinary retention
- B. Total spinal analgesia
- C. Hypopnoea
- D. Hypertension (Correct Answer)
Post-Anesthesia Care Explanation: ***Hypertension***
- Epidural anesthesia commonly causes **vasodilation** and a subsequent drop in **blood pressure** (hypotension), not hypertension, due to sympathetic blockade.
- While hypertension can occur due to pain or anxiety during the procedure, it is not a direct physiological complication of the epidural anesthetic itself.
*Urinary retention*
- Epidural anesthesia can affect the nerves controlling the **bladder**, leading to temporary **urinary retention**.
- This is a common complication, often requiring catheterization until the epidural wears off.
*Total spinal analgesia*
- This occurs if the epidural needle inadvertently punctures the **dura** and a large dose of local anesthetic is injected into the **subarachnoid space**.
- It results in widespread **sensory and motor blockade**, potentially leading to respiratory arrest and hemodynamic collapse.
*Hypopnoea*
- High epidural blocks or accidental **intrathecal administration** can cause paralysis of **intercostal muscles** and the diaphragm.
- This can lead to **respiratory depression** (hypopnoea) or even apnea, necessitating ventilatory support.
Post-Anesthesia Care Indian Medical PG Question 4: Most sensitive method of monitoring cardiovascular ischemia in the perioperative period is -
- A. NIBP
- B. ECG
- C. Pulse oximeter
- D. TEE (Correct Answer)
Post-Anesthesia Care Explanation: ***TEE***
- **Transesophageal echocardiography (TEE)** is the most sensitive method for detecting perioperative myocardial ischemia because it can visualize **regional wall motion abnormalities** and changes in **ventricular function** much earlier than ECG.
- **Ischemia** directly impairs the contractility of the affected myocardium, leading to subtle changes in wall motion that TEE can identify.
*NIBP*
- **Non-invasive blood pressure (NIBP)** monitoring can detect **hemodynamic changes** (like hypotension or hypertension) that may precede or accompany ischemia.
- However, these changes are **non-specific** and occur relatively late, making NIBP a less sensitive indicator of early ischemia.
*ECG*
- **Electrocardiography (ECG)** monitors the electrical activity of the heart and can detect **ST-segment changes** indicative of ischemia.
- While useful, ECG changes may appear later than wall motion abnormalities, and **silent ischemia** can be missed if the leads are not optimally placed or if the ischemia does not produce significant electrical changes.
*Pulse oximeter*
- A **pulse oximeter** measures **oxygen saturation** in the peripheral blood.
- It is primarily used to assess **respiratory function** and tissue oxygenation, and it does not directly monitor myocardial ischemia or cardiac function.
Post-Anesthesia Care Indian Medical PG Question 5: Shivering observed in the early part of the postoperative period is due to
- A. Hypothermia (Correct Answer)
- B. Pain
- C. Emergence delirium
- D. Drug withdrawal
Post-Anesthesia Care Explanation: **Hypothermia**
- Shivering is a primary physiological response to **hypothermia**, an attempt by the body to generate **heat** by increasing muscle activity.
- Patients often experience a drop in core body temperature during surgery due to factors like cold operating rooms, exposed body cavities, and anesthetic effects.
*Pain*
- While pain can cause discomfort and muscle tension, it typically does not manifest as generalized **shivering** in the early postoperative period.
- Pain is usually managed with analgesics, and shivering is more indicative of a **thermoregulatory disturbance**.
*Emergence delirium*
- Emergence delirium is characterized by disorientation, agitation, and non-purposeful movements, but not primarily by **shivering**.
- This condition is often related to the residual effects of anesthetic agents or anxiety upon waking.
*Drug withdrawal*
- Drug withdrawal can cause tremors and agitation, but it is less likely to present as **shivering** in the immediate postoperative period in a patient without a known history of substance dependence.
- Withdrawal symptoms typically manifest hours to days after the cessation of the drug, depending on its half-life.
Post-Anesthesia Care Indian Medical PG Question 6: In the TRIAGE system for disaster management, which of the following color codes denotes "high-priority treatment and/or transfer"?
- A. Red (Correct Answer)
- B. Black
- C. Yellow
- D. Green
Post-Anesthesia Care Explanation: ***Red***
- The **red tag** in the TRIAGE system signifies critical injuries requiring **immediate intervention** and transport to save life or limb.
- Patients tagged red have a high priority for treatment with a good chance of survival if attended to promptly.
- This represents the **highest priority** category for "high-priority treatment and/or transfer."
*Green*
- The **green tag** indicates patients with **minor injuries** who can walk and care for themselves.
- Also known as the "**walking wounded**," these patients require minimal or delayed medical attention.
- They have the **lowest priority** in disaster triage and can wait hours for treatment.
*Black*
- A **black tag** indicates the patient is **deceased** or has injuries so severe that survival is unlikely given the available resources.
- These patients are assigned a low priority for treatment to allocate resources to those with a better prognosis.
- Also called "**expectant**" in some systems.
*Yellow*
- The **yellow tag** designates patients with **serious, but non-life-threatening injuries** who can wait for treatment for a few hours.
- These patients are stable enough that they do not require immediate intervention but will need medical attention.
- Examples include fractures, moderate burns, or stable abdominal injuries.
Post-Anesthesia Care Indian Medical PG Question 7: All are management of PDPH except-
- A. Stool softeners (Correct Answer)
- B. Analgesic + caffeine
- C. Intravenous / oral fluids
- D. Upright position
Post-Anesthesia Care Explanation: ***Stool softeners***
- While **stool softeners** may be prescribed to prevent **straining** in patients experiencing PDPH, they do not directly treat the underlying cause or symptoms of PDPH.
- The primary goal of PDPH management is to re-establish **CSF pressure** and relieve headache, which stool softeners do not achieve.
*Analgesic + caffeine*
- **Caffeine** is a common component of PDPH management as it causes **cerebral vasoconstriction**, which can help alleviate the headache.
- **Analgesics** (e.g., NSAIDs, opioids) are used to manage the pain associated with PDPH.
*Intravenous / oral fluids*
- Increasing **fluid intake**, both oral and intravenous, helps to promote **CSF production** and potentially increase intracranial pressure, thereby alleviating PDPH symptoms.
- This is a supportive measure for rehydration and to potentially restore **CSF volume**.
*Upright position*
- An **upright position** typically **worsens** PDPH symptoms because it increases the gravitational pull on the CSF, further lowering intracranial pressure.
- Patients with PDPH are usually advised to maintain a **supine (flat)** position to minimize headache severity.
Post-Anesthesia Care Indian Medical PG Question 8: Awareness during anaesthesia can be assessed by:
- A. ARTERIAL B.P
- B. ETCO2
- C. BIS (Correct Answer)
- D. NEUROMUSCULAR MONITOR
Post-Anesthesia Care Explanation: ***
Post-Anesthesia Care Indian Medical PG Question 9: Which of the following agents is used for the treatment of post operative shivering?
- A. Atropine
- B. Thiopentone
- C. Pethidine (Correct Answer)
- D. Suxamethonium
Post-Anesthesia Care Explanation: ***Pethidine***
- **Pethidine (meperidine)** is a **synthetic opioid** known for its **mu-receptor agonism** and weak anticholinergic properties, making it effective in treating **post-operative shivering**.
- Its mechanism in reducing shivering is thought to involve modulation of the **thermoregulatory center** in the hypothalamus.
*Atropine*
- **Atropine** is an **anticholinergic drug** that primarily blocks muscarinic acetylcholine receptors, leading to effects like increased heart rate and decreased secretions.
- It does not directly act on the thermoregulatory centers or muscle activity responsible for shivering.
*Thiopentone*
- **Thiopentone** is a **barbiturate** used as an intravenous anesthetic, primarily for induction of anesthesia.
- While it has CNS depressant effects, it is not indicated or effective for the specific treatment of post-operative shivering.
*Suxamethonium*
- **Suxamethonium (succinylcholine)** is a **depolarizing neuromuscular blocker** used to induce muscle paralysis, typically for intubation.
- It would prevent shivering by paralyzing skeletal muscles, but this is a dangerous and inappropriate treatment for shivering due to its profound respiratory depressant effects.
Post-Anesthesia Care Indian Medical PG Question 10: What type of respiratory failure is most commonly observed in post-operative patients?
- A. Hypercapnic respiratory failure
- B. Mixed respiratory failure
- C. Perioperative respiratory failure
- D. Hypoxemic respiratory failure (Correct Answer)
Post-Anesthesia Care Explanation: ***Hypoxemic respiratory failure***
- **Hypoxemic respiratory failure** (Type I) is characterized by a **PaO2 less than 60 mmHg** with a normal or low PaCO2, often due to **V/Q mismatch** and **shunt**.
- Post-operative patients frequently develop **atelectasis**, **pneumonia**, or **pulmonary edema**, leading to impaired gas exchange and reduced oxygenation.
- This is the **most commonly observed type** in the immediate post-operative period.
*Hypercapnic respiratory failure*
- **Hypercapnic respiratory failure** (Type II) is primarily due to **alveolar hypoventilation**, resulting in a **PaCO2 greater than 50 mmHg**.
- While it can occur post-operatively, it is less common than hypoxemic failure and is typically seen with significant **sedation**, **neuromuscular blockade**, or severe **obstructive lung disease**.
*Mixed respiratory failure*
- **Mixed respiratory failure** involves both **hypoxemia** and **hypercapnia**, indicating severe impairment in both oxygenation and ventilation.
- Although it can occur in severe post-operative complications, it is not the *most commonly observed initial presentation* compared to isolated hypoxemia.
*Perioperative respiratory failure*
- **Perioperative respiratory failure** (Type III) occurs specifically in the surgical setting and involves atelectasis from changes in chest wall mechanics.
- While this occurs in the post-operative context, the term is less commonly used, and the **underlying mechanism is primarily hypoxemic** in nature.
