ANSWERS(VERIFIED ANSWERS)|AGRADE
1. QUESTION: Which of the following would be the earliest
auscultatory finding in left ventricular failure (LVF)?
- Crackles
- S3
- Murmur of mitral regurgitation
- Pericardial friction rub
Answer: B. S3
Rationale: The document provides "B. S3" and notes "LVF
would be the most subtle because early changes are usually subtle changes," indicating S3 as the earliest finding.
2. QUESTION: A patient with a triple-lumen subclavian
catheter has been receiving total parenteral nutrition, maintenance fluids, and antibiotics by the catheter. He has been slightly confused. Suddenly he grasps the catheter and pulls it out. He then complains of shortness of breath, and his pulse oximetry indicates an SpO2 of 84%. How should this patient be positioned?
- Head down, left side
- Head down, right side
- Head of bed elevated, left side
- | P a g e
- Head of bed elevated, right side
Answer: A. Head down, left side
Rationale: The document provides "A. Head down, left side"
and explains it reduces air embolism movement from the right heart, envisioning "a big air bubble in the patient’s heart."
3. QUESTION: Oxygen delivery (DO2) is the product of which
of the following?
- PaO2, hemoglobin, mean arterial pressure
- SaO2, hemoglobin, cardiac output
- SvO2, cardiac index, SaO2
- PaO2, mean arterial pressure, SvO2
Answer: B. SaO2, hemoglobin, cardiac output
Rationale: The document provides "B. SaO2, hemoglobin,
cardiac output," noting "Oxygen is delivered from the arterial end, so choose an option that has SaO2."
4. QUESTION: Which of the following is the most significant
complication of status asthmaticus?
- Pulmonary embolism
- Acute respiratory failure
- Hypertension
- Anaphylaxis
- | P a g e
Answer: B. Acute respiratory failure
Rationale: The document provides "B. Acute respiratory
failure" as the most significant complication.
5. QUESTION: A 22-year-old man is admitted to the critical
care unit after a motor vehicle collision. The emergency department nurse reports that he was unconscious at the scene of the accident, but he is now alert and oriented. Skull films show a linear fracture of the right temporal bone. He is at significant
risk for:
- scalp hematoma
- subdural hematoma
- epidural hematoma
- intracerebral hematoma
Answer: C. epidural hematoma
Rationale: The document provides "C. epidural hematoma,"
explaining "Linear fractures of the temporal bone frequently disrupt the middle meningeal artery and cause epidural hematoma," with a classic lucid interval.
6. QUESTION: A patient is admitted to the ICU after sustaining
a concussion and blunt abdominal trauma to the right upper quadrant in a domestic dispute. The patient’s vital signs are BP 145/86 mm Hg, pulse 86 beats/min, respiration 15 breaths/min, and temperature 98.8° F. The nurse is monitoring the patient’s

bowel sounds, abdominal tenderness, and abdominal girth frequently. Which of the following laboratory parameters is especially important for the nurse to closely monitor for bleeding in this patient?
- Platelet count
- Protime
- Hematocrit
- Mean corpuscular volume
Answer: C. Hematocrit
Rationale: The document provides "C. Hematocrit," noting it’s
key for monitoring intra-abdominal bleeding in blunt trauma, unlike platelet count, protime, or mean corpuscular volume.
7. QUESTION: Which of the following is associated with chest
pain, confusion, and petechiae?
- Dissecting aneurysm
- Fat embolism
- Pneumothorax
- Myocardial infarction
Answer: B. Fat embolism
Rationale: The document provides "B. Fat embolism," stating
"Chest pain, confusion, and petechiae are suggestive of a fat embolism," with petechiae as the clincher.
