Introduction
This comprehensive practice examination is designed to rigorously assess the
knowledge and clinical acumen expected of a candidate for TBS Phase 1 Exam 2.
The questions are structured to evaluate a deep understanding of foundational
medical theory, applied professional practice, and critical decision-making in high-
stakes environments. It features a variety of multiple-choice and scenario-based
questions that mimic real-world emergencies, testing your ability to synthesize
information, prioritize care, and apply protocols effectively. This assessment
emphasizes the application of evidence-based guidelines, regulatory compliance,
and ethical standards essential for a competent provider. Each question is followed
by a detailed explanation to reinforce learning and solidify understanding, ensuring
you are thoroughly prepared to demonstrate your proficiency.

SECTION ONE: QUESTIONS 1 – 50
1. A 68-year-old male presents with sudden onset of severe, tearing chest pain
radiating to his back. His blood pressure is 180/100 mmHg, and he has a history
of hypertension. What is the most likely diagnosis?
A. Acute myocardial infarction
B. Pulmonary embolism
C. Aortic dissection
D. Pericarditis
🟢 Correct Answer: C. Aortic dissection
🔴 Explanation: Aortic dissection typically presents with sudden, severe, tearing
chest pain that radiates to the back, often associated with uncontrolled
hypertension. This classic presentation distinguishes it from other causes of chest
pain.
2. According to ACLS guidelines, what is the first-line medication for a patient in
pulseless ventricular tachycardia (VTach)?
A. Amiodarone 300 mg IV push
B. Epinephrine 1 mg IV push
C. Lidocaine 1.5 mg/kg IV push
D. Magnesium sulfate 2 g IV push
🟢 Correct Answer: A. Amiodarone 300 mg IV push
🔴 Explanation: Amiodarone is the first-line antiarrhythmic for shock-refractory
pulseless VTach/VFib. The recommended initial dose is 300 mg IV/IO push.
Epinephrine is given after the second shock and then every 3-5 minutes, but it is
not the first-line antiarrhythmic.
,3. A patient is experiencing a severe anaphylactic reaction after receiving
penicillin. Which of the following is the priority intervention?
A. Administer oral diphenhydramine
B. Administer epinephrine 1:1000 intramuscularly
C. Start an IV infusion of normal saline
D. Administer albuterol via nebulizer
🟢 Correct Answer: B. Administer epinephrine 1:1000 intramuscularly
🔴 Explanation: Epinephrine is the primary and most critical medication for
anaphylaxis. It works rapidly to reverse vasodilation, bronchoconstriction, and
laryngeal edema. The preferred route is intramuscular in the anterolateral thigh.
4. A 45-year-old female is involved in a motor vehicle collision. She is conscious
but complaining of severe abdominal pain. Her pulse is 120/min, and her blood
pressure is 90/60 mmHg. Which of the following findings would be most
concerning for intra-abdominal hemorrhage?
A. Bruising over the left lower ribs
B. Patient reports pain with deep palpation
C. Presence of a seatbelt sign across the abdomen
D. Initial hematocrit of 35%
🟢 Correct Answer: C. Presence of a seatbelt sign across the abdomen
🔴 Explanation: A seatbelt sign, or bruising across the lower abdomen, is a highly
concerning indicator of potential intra-abdominal injury, including bowel
perforation or mesenteric hemorrhage, and warrants a high index of suspicion for
internal injury.
5. A patient is found unresponsive with a respiratory rate of 6/min. What is the
most appropriate immediate action?
, A. Place the patient in the recovery position
B. Perform a head-tilt chin-lift and provide two rescue breaths
C. Check for a carotid pulse for 10 seconds
D. Begin chest compressions immediately
🟢 Correct Answer: C. Check for a carotid pulse for 10 seconds
🔴 Explanation: In an unresponsive patient with abnormal breathing (agonal or <
12/min), the provider must first check for a carotid pulse for no more than 10
seconds to determine if the patient is in cardiac arrest. This step guides the
decision to start CPR or ventilations.
6. Which of the following best describes the principle of "implied consent" in
emergency medical services?
A. A competent patient's expressed refusal of care is honored
B. Consent is assumed for an unconscious patient in a life-threatening emergency
C. A parent or legal guardian provides permission for a minor child
D. A patient provides verbal agreement to a specific procedure
🟢 Correct Answer: B. Consent is assumed for an unconscious patient in a life-
threatening emergency
🔴 Explanation: Implied consent is based on the legal principle that a reasonable
person would consent to life-saving care if they were able to do so. It is applied
when a patient is unconscious or otherwise unable to provide consent and is
facing a life-threatening emergency.
7. A 7-year-old child is in respiratory distress with stridor, a barking cough, and a
low-grade fever. Which of the following is the most likely diagnosis?
A. Epiglottitis
B. Asthma exacerbation
