Post-Discharge Analgesia Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Post-Discharge Analgesia. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Post-Discharge Analgesia Indian Medical PG Question 1: A patient after undergoing thoracotomy complains of severe pain. The BEST method of pain control in this patient would be:
- A. Oral morphine
- B. Diazepam rectal suppository
- C. Intercostal cryoanalgesia (Correct Answer)
- D. IV fentanyl
Post-Discharge Analgesia Explanation: ***Intercostal cryoanalgesia***
- **Intercostal cryoanalgesia** involves applying extreme cold to the intercostal nerves, leading to temporary nerve denervation and prolonged pain relief. This technique is particularly effective for **post-thoracotomy pain** due to its targeted action and reduced systemic side effects compared to opioids.
- The goal is to provide **long-lasting pain control** specifically at the surgical site, allowing for better respiratory mechanics and early mobilization.
*Oral morphine*
- Oral morphine can provide systemic pain relief, but its onset of action is slower, and it carries the risk of significant **sedation** and **respiratory depression**, which are major concerns in a patient who has just undergone thoracotomy.
- While effective, it may not provide optimal local pain control for incisional pain and often requires higher doses to achieve adequate relief, increasing the risk of adverse effects.
*Diazepam rectal suppository*
- Diazepam is a **benzodiazepine** primarily used for anxiety, muscle spasms, and seizures, not for severe acute surgical pain. It has **no significant analgesic properties**.
- Its sedative effects would be contraindicated after thoracotomy due to the risk of respiratory depression and masking potential neurological changes.
*IV fentanyl*
- IV fentanyl is a potent opioid with a rapid onset and short duration of action, making it useful for breakthrough pain or during immediate post-operative periods. However, it requires **continuous monitoring** and frequent re-dosing.
- Like other opioids, it carries risks of **respiratory depression**, nausea, and sedation, making it less ideal for sustained primary pain control immediately after thoracotomy where lung function is critical.
Post-Discharge Analgesia Indian Medical PG Question 2: All of the following can be routes of opioid administration except:
- A. Intramuscular
- B. Oral
- C. Intravenous
- D. Intradermal (Correct Answer)
Post-Discharge Analgesia Explanation: ***Intradermal***
- **Intradermal administration** involves injecting medication into the dermis, the layer between the epidermis and the subcutaneous tissue, and is typically used for **allergy testing** or **tuberculosis screening (PPD test)**, not for systemic opioid delivery.
- The **slow absorption rate** and **small volume capacity** of the dermal layer make it unsuitable for achieving therapeutic opioid concentrations quickly or effectively.
*Intramuscular*
- **Intramuscular (IM)** injection allows for **rapid absorption** of opioids into the bloodstream from the muscle tissue.
- It is a common route for administering **analgesics**, including opioids, especially in settings where oral administration is not feasible or faster onset is desired.
*Oral*
- **Oral (PO) administration** is a common and convenient route for many opioid formulations, allowing for **systemic absorption** through the gastrointestinal tract.
- Opioids like **oxycodone**, **hydrocodone**, and **morphine** are often prescribed as oral tablets or solutions for pain management.
*Intravenous*
- **Intravenous (IV) administration** provides the **fastest onset of action** for opioids, as the medication is directly introduced into the bloodstream.
- This route is critically important in **acute pain management**, surgical settings, and emergency situations where immediate pain relief is necessary.
Post-Discharge Analgesia Indian Medical PG Question 3: Which block is described as regional anesthesia of the arm:-
- A. Interscalene block
- B. Infraclavicular block
- C. Axillary block
- D. Supraclavicular brachial plexus block (Correct Answer)
Post-Discharge Analgesia Explanation: ***Supraclavicular brachial plexus block***
- The **supraclavicular block** targets the **trunks of the brachial plexus** as they exit the scalene muscles, providing comprehensive anesthesia to the entire upper limb, including the shoulder, arm, forearm, and hand.
- This block is particularly effective for procedures involving the arm due to its proximal location within the brachial plexus, covering multiple nerve distributions.
*Interscalene block*
- An **interscalene block** primarily targets the **roots or trunks of the brachial plexus** and is typically used for shoulder and upper arm surgery, but may spare the ulnar nerve.
- While it anesthetizes the arm, it is primarily chosen for more proximal procedures and may not provide complete distal arm anesthesia compared to the supraclavicular approach.
*Infraclavicular block*
- An **infraclavicular block** targets the **cords of the brachial plexus** and is suitable for procedures involving the elbow, forearm, and hand, providing good coverage for these areas.
- While it does anesthetize the distal arm, it is more distal than the supraclavicular block and may not provide full coverage for the entire upper arm and shoulder.
*Axillary block*
- An **axillary block** targets the **terminal branches of the brachial plexus** in the axilla, mainly anesthetizing the forearm and hand.
- This block is often used for procedures distal to the elbow and provides less comprehensive coverage for the entire upper arm and shoulder compared to more proximal blocks.
Post-Discharge Analgesia Indian Medical PG Question 4: A 50-year-old patient with renal insufficiency was recently operated on for pyelolithotomy. Which drug is the most appropriate choice for post-operative analgesia?
- A. Diclofenac sodium
- B. Naproxen
- C. Indomethacin
- D. Acetaminophen (Correct Answer)
- E. Ketorolac
Post-Discharge Analgesia Explanation: ***Acetaminophen***
- **Acetaminophen** is primarily metabolized in the liver, with minimal renal excretion, making it a safer option for patients with **renal insufficiency**.
- It provides effective **analgesia** without the adverse renal effects associated with NSAIDs.
*Diclofenac sodium*
- **Diclofenac** is a non-steroidal anti-inflammatory drug (**NSAID**) that can impair renal function, especially in patients with pre-existing **renal insufficiency**, by inhibiting prostaglandin synthesis.
- Its use can lead to further **kidney damage** or exacerbate existing renal impairment.
*Naproxen*
- **Naproxen** is an **NSAID** that carries a significant risk of causing acute kidney injury in patients with **compromised renal function**.
- It reduces renal blood flow and glomerular filtration rate, making it unsuitable for this patient.
*Indomethacin*
- **Indomethacin** is a potent **NSAID** known for its adverse renal effects, including acute renal failure.
- It should be avoided in patients with **renal insufficiency** due to its potential to further decline kidney function.
*Ketorolac*
- **Ketorolac** is a potent **NSAID** commonly used for post-operative pain but is **contraindicated** in patients with renal insufficiency.
- It has significant nephrotoxic potential and can cause acute renal failure, especially in patients with pre-existing kidney disease.
Post-Discharge Analgesia Indian Medical PG Question 5: 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
Post-Discharge Analgesia 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.
Post-Discharge Analgesia Indian Medical PG Question 6: During the discharge of a COVID patient treated with steroids and remdesivir, which of the following will you inform him about?
1. Repeat RT-PCR after 7 days of discharge
2. Watch for the persistence of Anosmia
3. Watch for headache and nasal discharge
4. Monitor glucose levels
5. Watch for Sinusitis symptoms
- A. 1,3 and 4
- B. 3,4 and 5 (Correct Answer)
- C. 2,3 and 4
- D. 1,2,3,4 and 5
Post-Discharge Analgesia Explanation: **3, 4, and 5**
- For patients treated with **steroids**, it is crucial to monitor **glucose levels** due to the potential for steroid-induced hyperglycemia [1].
- Symptoms like **headache** and **nasal discharge** (and by extension **sinusitis symptoms**) could indicate conditions like **mucormycosis**, a serious fungal infection seen in immunocompromised COVID-19 patients, especially those having received steroids.
*1, 3, and 4*
- A **repeat RT-PCR after 7 days** of discharge is generally not recommended as per current guidelines, as viral shedding can persist without infectivity.
- While monitoring for headache, nasal discharge, and glucose levels is appropriate, omitting the direct vigilance for **sinusitis symptoms** is less comprehensive.
*2, 3, and 4*
- While **anosmia** (loss of smell) can persist post-COVID, it is primarily a lingering symptom of the infection itself and typically resolves spontaneously, not usually requiring specific discharge instructions for monitoring its persistence to prevent complications.
- The focus should be on new or worsening symptoms that might indicate post-COVID complications or secondary infections.
*1, 2, 3, 4, and 5*
- Including **repeat RT-PCR** and solely "watch for the persistence of Anosmia" without emphasizing resolution or specific actions makes this option less pertinent for discharge advice.
- The priority for discharge instructions should be preventable complications and warning signs of serious conditions.
Post-Discharge Analgesia Indian Medical PG Question 7: Which of the following is the FIRST-LINE antiemetic drug most commonly used for post-operative nausea and vomiting (PONV) prophylaxis?
- A. Lorazepam
- B. Metoclopramide
- C. Promethazine
- D. Ondansetron (Correct Answer)
Post-Discharge Analgesia Explanation: ***Ondansetron***
- **Ondansetron** is a **5-HT3 receptor antagonist** and is considered a first-line agent due to its high efficacy and favorable side effect profile in preventing PONV.
- It works by blocking serotonin receptors in the **chemoreceptor trigger zone** and the **gastrointestinal tract**, reducing the sensation of nausea and vomiting.
*Lorazepam*
- **Lorazepam** is a **benzodiazepine** primarily used for its **anxiolytic** and **sedative effects**, and sometimes as an adjunct for refractory nausea, but not as a first-line antiemetic for PONV prophylaxis.
- While it can help indirectly by reducing anxiety, it does not directly target the key pathways involved in PONV as effectively as 5-HT3 antagonists.
*Phenytoin*
- **Phenytoin** is an **anticonvulsant** medication used to prevent seizures and has no role in the direct treatment or prophylaxis of PONV.
- It primarily acts on voltage-gated sodium channels in neurons and does not possess antiemetic properties.
*Metoclopramide*
- **Metoclopramide** is a **dopamine D2 receptor antagonist** and a **prokinetic agent** that can be used for PONV, particularly when gastric stasis is a concern.
- However, it is generally considered a second-line agent due to the risk of **extrapyramidal side effects**, especially with higher doses or prolonged use.
*Promethazine*
- **Promethazine** is a **first-generation antihistamine** with **antidopaminergic** and **anticholinergic properties** that can be effective for nausea and vomiting.
- It is often used as a rescue antiemetic or in combination therapy, but its sedative effects and potential for extrapyramidal symptoms make it less preferable as a first-line prophylactic agent compared to ondansetron.
Post-Discharge Analgesia Indian Medical PG Question 8: Which of the following anesthetic agents have good analgesic property? a) Ketamine b) Nitrous oxide c) Thiopentone d) Propofol e) Midazolam
- A. Ketamine and Nitrous oxide (Correct Answer)
- B. Ketamine only
- C. Nitrous oxide and Thiopentone
- D. Ketamine and Propofol
- E. Midazolam only
Post-Discharge Analgesia Explanation: ***Ketamine and Nitrous oxide***
- **Ketamine** is a dissociative anesthetic with potent **analgesic properties** secondary to its action as an **NMDA receptor antagonist**.
- **Nitrous oxide** is an inhalational anesthetic known for its mild to moderate **analgesic effects**, making it useful for sedation and pain relief.
*Ketamine only*
- While **ketamine** has excellent analgesic properties, this option is incomplete as **nitrous oxide** also contributes significant analgesia among the choices.
- Excluding other agents with analgesic properties makes this option less comprehensive than the correct answer.
*Ketamine and Propofol*
- **Ketamine** possesses strong analgesic effects, but **propofol** is a sedative-hypnotic agent with no significant intrinsic **analgesic properties**.
- Propofol provides anesthesia and sedation but typically requires co-administration with opioids for pain control.
*Nitrous oxide and Thiopentone*
- **Nitrous oxide** provides analgesia, but **thiopentone** (a barbiturate) is primarily an anesthetic and sedative with **no significant analgesic properties**.
- Thiopentone can induce unconsciousness rapidly but does not relieve pain.
*Midazolam only*
- **Midazolam** is a benzodiazepine primarily used for sedation, anxiolysis, and amnesia, with **no intrinsic analgesic properties**.
- Its effects can reduce stress and perception of pain, but it does not directly act as an analgesic.
Post-Discharge Analgesia Indian Medical PG Question 9: Which of the following anaesthetic agent lacks analgesic effect?
A) N2O
B) Thiopentone
C) Methohexitone
D) Ketamine
E) Fentanyl
- A. N2O
- B. Methohexitone
- C. Ketamine
- D. Fentanyl
- E. Thiopentone (Correct Answer)
Post-Discharge Analgesia Explanation: ***Thiopentone***
- Thiopentone is a **barbiturate** anesthetic primarily used for inducing anesthesia.
- It provides significant **hypnosis** and sedation but lacks intrinsic **analgesic properties**, meaning it does not relieve pain.
*N2O*
- **Nitrous oxide** (N2O) is an inhalation anesthetic that provides good **analgesia** at sub-anesthetic concentrations.
- It is often used as an adjunct to other anesthetic agents to enhance pain relief during procedures.
*Methohexitone*
- Methohexitone is another **barbiturate** similar to thiopentone, used for induction of anesthesia.
- While it provides rapid **hypnosis**, it also lacks significant **analgesic effects**.
*Ketamine*
- Ketamine is a **dissociative anesthetic** known for its potent **analgesic properties**.
- It works by blocking **NMDA receptors**, providing pain relief even at sub-anesthetic doses.
*Fentanyl*
- Fentanyl is a powerful **opioid analgesic** that is commonly used in anesthesia for its strong pain-relieving effects.
- It acts on **opioid receptors** in the central nervous system to reduce pain perception.
Post-Discharge Analgesia Indian Medical PG Question 10: Which intravenous anaesthetic agent has analgesic effect also
- A. Thiopentone
- B. Ketamine (Correct Answer)
- C. Propofol
- D. Etomidate
Post-Discharge Analgesia Explanation: ***Ketamine***
- Ketamine acts as an **N-methyl-D-aspartate (NMDA) receptor antagonist**, providing significant **analgesia** in addition to its anaesthetic effects.
- It induces a state of **dissociative anaesthesia**, where the patient appears awake but is unresponsive to pain, making it unique among intravenous anaesthetics.
*Thiopentone*
- Thiopentone is a **barbiturate** that acts as a potent hypnotic and anaesthetic but provides no significant analgesic properties.
- It can even cause **anti-analgesia** (hyperalgesia) at sub-hypnotic doses, increasing sensitivity to pain.
*Propofol*
- Propofol is a potent intravenous anaesthetic that works primarily as a **GABA-A receptor agonist**, but it lacks intrinsic analgesic properties.
- While it can cause some sedation and reduced pain perception due to CNS depression, it does not directly modulate pain pathways in the way an analgesic would.
*Etomidate*
- Etomidate is a hypnotic agent highly valued for its **cardiovascular stability**, making it suitable for patients with compromised cardiac function.
- Like propofol and thiopentone, etomidate primarily acts on **GABA-A receptors** to induce unconsciousness and offers no significant analgesic effects.
