A 70 y.o woman with ischemic colitis and pneumonia is in the ICU. She is ventilator-dependent and paralyzed. She requires specialized nutrition support and the Harris Benedict equation has been used to calculate her Basal Metabolic Rate (BMR). Her daily caloric needs are:
Equivalent to her BMR
BMR x a disease stress factor. No activity factor is required as she is paralyzed and vent-dependent
BMR x an activity factor. No disease stress factor is required because the Harris-Benedict equation accounts for her disease state
BMR x disease stress factor x activity factor
Cannot be calculated because the Harris-Benedict equation should not be used for ICU patients
You are the attending for a 92yo woman who has a history of DM, CHF, atrial fibrillation, and mild cognitive impairment, who was admitted to the ICU following hip replacement after a fall. Prior to this fall, the patient lived independently at home and managed light housework activities, such as laundry and cooking, without difficulty. Her operative course was significant for persistent bleeding and hypotension. These issues were managed intraoperatively by transfusion of 4 units PRBCs and pressor support with norepinephrine. A central venous line and arterial line were placed intraoperatively to facilitate management.

The patient reports mild to moderate dyspnea and severe pain at the surgical site. Which of the following will be most effective approach to minimize this patient’s risk of delirium?
Start an infusion of dexmedetomidine
Start a scheduled atypical antipsychotic medication
Adjust the patient’s analgesic regimen to minimize use of opioid medications
Maintain as close to normal a sleep-wake cycle as feasible by increasing daytime activity, minimizing naps, enforcing overnight “quiet time” periods

Antibiotic prophylaxis used in conjunction with an antifungal agent is associated with less infectious complications.
It is recommended that prophylactic should be started on all patients with pancreatic necrosis.
It is most optimal to start prophylactic antibiotics within 24 hours of admission.
Antibiotic prophylaxis does not reduce mortality or protect against infected necrosis.
Antibiotic prophylaxis should be started on patients who demonstrated progression of pancreatic necrosis.
38 yo G2P0010 at 30+3 weeks of pregnancy admitted to the ICU with ARDS in the setting of urosepsis with new diagnosis of preeclampsia with severe features.

Your patient is a 75yo man with a long-history of diabetes complicated by neuropathy, COPD, and coronary artery disease. He is currently intubated following a pneumonia. His course has been significant for renal insufficiency, delirium and the development of a stage IV sacral pressure ulcer. He has intermittent agitation during the day, but he consistently grimaces and becomes agitated with dressing changes. These symptoms resolve with fentanyl; however, he consistently becomes somnolent after receiving this. His daughter, who is his health care agent, has asked that he not receive fentanyl because of the somnolence. His nurse objects, stating that the dressing changes are painful. His daughter turns to the patient and asks if he wants the pain medicine before the dressing changes, and he shakes his head, “no”. What is true about this patient’s ability to give or refuse consent?
This patient has delirium, and therefore cannot give or refuse consent.
A patient may refuse even beneficial therapy. This patient’s head shake is indicating refusal of premedication before the dressing changes, and so he should not receive the pain medicine.
His health care agent is refusing the premedication on behalf of her father, and so he should not receive the pain medicine.
The patient’s decisional capacity is unknown and should be evaluated before accepting his response as a refusal of therapy.
An ethics consult should be obtained since the health care agent is refusing the indicated premedication for a painful dressing change.

Labetalol, with an extraction ratio of 0.9
A patient is admitted to the ICU altered after an overdose. He arrives in the ICU and is found tachycardic to 140, with a blood pressure of 100/80, respiratory rate of 40 and temperature of 102. His exam is significant for diaphoresis, dilated pupils, bilateral lower extremity clonus and erythematous skin. Because of his worsening mental status, he is intubated in the ICU and started on sedation. Shortly afterwards, his heart rate increases to 180, he remains febrile and he develops inextinguishable clonus. Identify the toxidrome and etiology behind his worsening course?
Sympathomimetic toxidrome. He is worsening because he is not adequately sedated.
Anticholinergic toxidrome. He is worsening because he is continuing to release drug from a pharmacobezoar.
Serotonin syndrome. He is worsening because he was placed on fentanyl for sedation.
Cholinergic toxidrome. He is worsening because he was not given antidotal therapy.

EMS was activated and patient had successful return of spontaneous circulation after ACLS was initiated. Post-arrest EKG demonstrated anterior STEMI. Patient was transported to the hospital and was taken to the cardiac catheterization lab and had a successful primary percutaneous coronary intervention to the LAD.

A 60 y.o. male with obesity BMI=32, hypertension and hyperlipidemia is admitted to the MICU with severe Covid pneumonia. His symptoms (malaise, dyspnea and cough) started 5 days prior to presentation to the emergency room. Upon arrival to the emergency room his oxygen saturation was 86% on room air, HR=100, BP 124/ 78 and temparture=38 degrees Celsius. Supplemental oxygen was provided (4LPM). CXR revealed bilateral pulmonary infiltrates and his nasopharyngeal PCR was positive for Cvoid-19. He was admitted to hospital and started on remdesivir and dexamethasone. On hospital day 2 he was noted to have worsening hypoxemia and new confusion. His supplemental oxygen has been increased to 7 LPM nasal cannula. You are called to evaluate. On exam his RR=20, HR=110, BP=92/66 with SpO2=90%. He is arousable to sternal rub. He opens his eyes but does not interact or follow any commands. Auscultation of lungs is notable for scattered anterior rhonchi without wheezes. Next best step in management would be:

Initiate high flow nasal cannula (HFNC), adjust FiO2 to maintain SpO2 92-96% and begin awake prone ventilation trial
Initiate noninvasive ventilation
Intubate and begin invasive mechanical ventilation
