A 72-year-old woman with metastatic ovarian cancer is brought to the physician by her son because she is in immense pain and cries all the time. On a 10-point scale, she rates the pain as an 8 to 9. One week ago, a decision to shift to palliative care was made after she failed to respond to 2 years of multiple chemotherapy regimens. She is now off chemotherapy drugs and has been in hospice care. Current medications include 2 mg morphine intravenously every 2 hours and 650 mg of acetaminophen every 4 to 6 hours. The son is concerned because he read online that increasing the dose of morphine would endanger her breathing. Which of the following is the most appropriate next step in management?

Counsel patient and continue same opioid dose

Change morphine to a non-opioid analgesic

Initiate palliative radiotherapy

Initiate cognitive behavioral therapy

A 69-year-old man with aggressive metastatic cholangiocarcinoma presents after the second round of chemotherapy. He has suffered a great deal of pain from the metastasis to his spine, and he is experiencing side effects from the cytotoxic chemotherapy drugs. Imaging shows no change in the tumor mass and reveals the presence of several new metastatic lesions. The patient is not willing to undergo any more chemotherapy unless he gets something for pain that will “knock him out”. High-dose opioids would be effective, in his case, but carry a risk of bradypnea and sudden respiratory failure. Which of the following is the most appropriate next step in management?

Put him in a medically-induced coma during chemotherapy sessions

Continue another round of chemotherapy without opioids

Give a lower dose even though it has less efficacy

A 67-year-old woman is brought by ambulance from home to the emergency department after she developed weakness of her left arm and left face droop. According to her husband, she has a history of COPD, hypertension, and hyperlipidemia. She takes hydrochlorothiazide, albuterol, and atorvastatin. She is not on oxygen at home. She is an active smoker and has smoked a pack a day for 20 years. Her mother died of a heart attack at age 60 and her father died of prostate cancer at age 55. By the time the ambulance arrived, she was having difficulty speaking. Once in the emergency department, she is no longer responsive. Her blood pressure is 125/85 mm Hg, the temperature is 37.2°C (99°F), the heart rate is 77/min, and her breathing is irregular, and she is taking progressively deeper inspirations interrupted with periods of apnea. Of the following, what is the next best step?

Start tissue plasminogen activator (tPA)

Obtain non-contrast enhanced CT of brain

A 72-year-old man presents to the emergency department with chest pain and shortness of breath. An EKG demonstrates an ST elevation myocardial infarction, and he is managed appropriately. The patient suffers from multiple comorbidities and was recently hospitalized for a myocardial infarction. The patient has a documented living will, which specifies that he does wish to receive resuscitative measures and blood products but refuses intubation in any circumstance. The patient is stabilized and transferred to the medical floor. On day 2, the patient presents with ventricular fibrillation and a resuscitative effort occurs. He is successfully resuscitated, but his pulmonary parameters warrant intervention and are acutely worsening. The patient's wife, son, and daughter are present and state that the patient should be intubated. The patient's prognosis even with intubation is very poor. Which of the following describes the best course of action?

Do not intubate the patient given his living will

Intubate the patient - the family is representing the patient's most recent and accurate wishes

Consult the hospital ethics committee

Intubate the patient - a patient's next of kin take precedence over a living will

Do not intubate the patient as his prognosis is poor even with intubation

An 85-year-old man with terminal stage colon cancer formally designates his best friend as his medical durable power of attorney. After several courses of chemotherapy and surgical intervention, the patient’s condition does not improve, and he soon develops respiratory failure. He is then placed on a ventilator in a comatose condition. His friend with the medical power of attorney tells the care provider that the patient would not want to be on life support. The patient’s daughter disputes this and says that her father needs to keep receiving care, in case there should be any possibility of recovery. Additionally, there is a copy of the patient’s living will in the medical record which states that, if necessary, he should be placed on life support until full recovery. Which of the following is the most appropriate course of action?

The durable medical power of attorney’s decision should be followed.

Withdraw the life support since the patient’s chances of recovery are very low

Contact other family members to get their input for the patient

Act according to the patient’s living will

Follow the daughter’s decision for the patient

A 67-year-old man presents to the emergency department following an episode of chest pain and a loss of consciousness. The patient is in critical condition and his vital signs are rapidly deteriorating. It is known that the patient is currently undergoing chemotherapy for Hodgkin’s lymphoma. The patient is accompanied by his wife, who wants the medical staff to do everything to resuscitate the patient and bring him back. The patient also has 2 daughters, who are on their way to the hospital. The patient’s written advance directive states that the patient does not wish to be resuscitated or have any sort of life support. Which of the following is the appropriate course of action?

Respect the patient’s advance directive orders

Contact the patient’s siblings or other first-degree relatives

Take into account the best medical decision made by the physician for the patient

Respect the wife’s wishes and resuscitate the patient

Symptom management at end of life for USMLE Step 3: High-Yield Patient Safety Lessons

Pain Management - The Final Comfort

Goal: Patient comfort, not prolonging life or hastening death. Use a multimodal approach.
Assessment: Use a validated pain scale (e.g., Numeric Rating Scale 0-10).
Opioid Therapy: The cornerstone of severe pain management.
- Morphine is the gold-standard first-line agent.
- Start with short-acting opioids (e.g., oral morphine 5-15 mg q4h PRN).
- Convert to long-acting formulations (e.g., MS Contin, Fentanyl patch) once pain is stable.
- Titration: Increase dose by 25-50% for persistent pain. No ceiling dose.

WHO Analgesic Ladder for Cancer Pain Management

⭐ Principle of Double Effect: It is ethically permissible to administer potentially life-shortening medication (e.g., high-dose opioids) to relieve suffering, provided the primary intention is symptom relief, not causing death.

Respiratory Relief - Breath & Peace

Primary Goal: Alleviate the subjective sensation of dyspnea, not solely to correct underlying hypoxia.
Initial Management: First, identify and treat reversible causes (e.g., fluid overload, pneumonia, bronchospasm, PE).
Pharmacologic Therapy:
- Opioids: First-line treatment for refractory dyspnea.
  - Start low-dose Morphine (2.5-5 mg PO q4h PRN).
  - Titrate dose based on symptom relief.
- Anxiolytics: Benzodiazepines (e.g., lorazepam) can be added to manage anxiety associated with breathlessness.

⭐ Opioids are the standard of care for end-of-life dyspnea, regardless of pain presence. Their primary effect is central, reducing the brain's perception of air hunger.

Gut & Mind - Calm & Quiet

Nausea & Vomiting:
- Identify cause: Opioids, metabolic (↑Ca), GI obstruction.
- Agents: Haloperidol (broad-spectrum), Metoclopramide (prokinetic), Ondansetron (for chemo/radiation).
Constipation:
- Opioid-induced is near-universal. Prophylaxis is key.
- 📌 Mnemonic: "Mush & Push" - Docusate (softener) + Senna/Bisacodyl (stimulant).
- Methylnaltrexone for refractory cases (doesn't cross BBB).
Agitation & Delirium (Terminal):
- First, rule out/treat reversible causes (e.g., pain, urinary retention).
- Meds: Haloperidol is first-line. Lorazepam for refractory agitation.

⭐ Exam Favorite: Benzodiazepines (e.g., lorazepam) can worsen delirium in the elderly unless it's due to alcohol/benzo withdrawal. Use antipsychotics like haloperidol first.

Respiratory Secretions ("Death Rattle"):
- Caused by inability to clear oral secretions. Reposition patient first.
- Meds: Anticholinergics like Glycopyrrolate or Scopolamine.

High‑Yield Points - ⚡ Biggest Takeaways

Opioids (morphine) are the cornerstone for managing both pain and dyspnea; titrate to comfort, not fear of respiratory depression.

The "death rattle" (excess secretions) is treated with anticholinergics like scopolamine or glycopyrrolate.

For agitation and delirium, haloperidol is the drug of choice, not benzodiazepines, which can worsen confusion.

Always prescribe prophylactic laxatives (senna, docusate) with opioids to prevent severe constipation.

The doctrine of double effect ethically justifies providing palliative medications that may unintentionally hasten death.
