Question 1
Leftward QRS axis deviation is most classically associated with which condition according to the material?
Correct Answer:
Congestive heart failure
Explanation:
Leftward QRS axis deviation means the overall ventricular depolarization vector points more to the left. This often happens when the left ventricle is enlarged or hypertrophied due to chronic overload. In congestive heart failure, the heart undergoes remodeling with left-sided deterioration and increased left ventricular mass, which shifts the depolarization vector leftward. So a leftward axis on the ECG is a classic clue pointing toward congestive heart failure. In contrast, right axis deviation is more associated with right heart strain (such as from pulmonary embolism), while atrial fibrillation or pericarditis do not classically produce a specific leftward axis shift.
Question 2
Which scales are used to assess sedation and delirium in ICU patients?
Correct Answer:
RASS for sedation; CAM-ICU for delirium.
Explanation:
Assessing sedation and delirium in the ICU requires two complementary tools: one to measure how sedated a patient is, and another to detect delirium. The Richmond Agitation-Sedation Scale (RASS) provides a simple, validated way to rate a patient’s level of arousal from combative to unresponsive, with 0 indicating calm and alert. This helps guide sedative dosing and target a lighter level of sedation when appropriate, minimizing risks associated with deep sedation. For delirium, the CAM-ICU is designed to detect this cognitive disturbance in critically ill patients, including those who are nonverbal. It evaluates whether delirium is present by looking for acute changes or fluctuating mental status and inattention, plus either an altered level of consciousness or disorganized thinking. A positive CAM-ICU confirms delirium, which is important because delirium requires different management and has distinct prognostic implications from sedation depth. Other tools like APACHE II or SOFA measure overall illness severity, not sedation or delirium specifically. GCS gauges consciousness level but isn’t a delirium screen and isn’t sensitive enough to detect delirium as such. Using CAM-ICU to evaluate delirium and RASS to assess sedation provides the most accurate, practical approach for ICU patients.
Question 3
If an infection is suspected at a catheter insertion site, what is the safest immediate management?
Correct Answer:
Remove the catheter
Explanation:
When a catheter insertion site shows signs of infection, the source is most often the catheter itself and any biofilm forming on it. Removing the catheter promptly is the safest immediate step because it eliminates the nidus of bacteria and markedly lowers the risk of progression to catheter-related bloodstream infection or sepsis. After removal, confirm and treat as needed: obtain cultures (catheter tip culture if removed and peripheral blood cultures) and start empiric antibiotics if there are systemic signs of infection. If another line is required, place it at a different site with strict asepsis. Local antibiotics at the site won’t reliably eradicate catheter-associated infection, since the biofilm within the catheter is a common reservoir. Re-siting a catheter at a new site without removing the infected one risks ongoing infection. Ignoring the signs is unsafe because infection can progress, and bacteremia can occur even without fever.
Question 4
Which statement best describes fever management in ICU patients?
Correct Answer:
Investigate cause and treat infection when present; use acetaminophen; consider targeted temperature management in appropriate neuro cases; avoid unnecessary aggressive cooling.
Explanation:
Fever management in the ICU is about identifying and addressing the underlying cause while using fever-reducing strategies judiciously. The best approach is to investigate possible infection and treat it when present, rather than assuming all fevers require aggressive cooling. Acetaminophen is commonly used to bring down fever and ease discomfort. In certain neurological scenarios, targeted temperature management can be considered because it may benefit brain protection or recovery, but outside those appropriate cases, routine aggressive cooling is avoided due to risks like shivering, increased metabolic demand, and other complications. Fever should not be waited on for a fixed period or treated only with antibiotics; antibiotics are indicated only when infection is suspected or proven. The key is a thoughtful, cause-directed plan rather than blanket cooling for all ICU fevers.
Question 5
What is the initial management step in shock according to the material?
Correct Answer:
Fluid administration
Explanation:
Restoring circulating volume with intravenous fluids is the first step in shock management. Shock leads to inadequate tissue perfusion, and the quickest way to improve perfusion is to increase the intravascular volume so the heart can pump more effectively. Start with isotonic crystalloids (such as normal saline or lactated Ringer’s), giving a bolus and reassessing response. A typical initial approach is about 20–30 mL/kg, repeated as needed, guided by blood pressure, urine output, mental status, and signs of perfusion. If perfusion remains uncertain after adequate fluid administration, vasopressors are added to maintain target blood pressure while continuing fluid resuscitation. Blood transfusion is not the initial step unless there is ongoing hemorrhage or severe anemia. Observation alone would not address the urgent perfusion deficit in shock.
