What is an escharotomy and why is it performed?
- A. A surgical incision made to improve circulation in burn injuries
- B. A procedure to remove dead tissue from a wound
- C. A procedure to remove excess fluid from the lungs
- D. A procedure to relieve pain from burns
Correct Answer: A
Rationale: An escharotomy is a surgical procedure involving an incision through the eschar (dead tissue) to relieve pressure in burn injuries. It is performed to improve circulation to the affected area, prevent further damage, and restore blood flow. Choice B is incorrect because an escharotomy is not primarily focused on removing dead tissue but rather on relieving pressure. Choice C is incorrect as it describes a procedure related to pulmonary issues, not burn injuries. Choice D is incorrect because while pain relief may be a result of an escharotomy, it is not the primary purpose of the procedure.

What is the first medication to give for wheezing due to an allergic reaction?
- A. Albuterol via nebulizer
- B. Cromolyn 20 mg via nebulizer
- C. Methylprednisolone 100 mg IV
- D. Aminophylline 500 mg IV
Correct Answer: A
Rationale: Albuterol is the first-line medication for treating wheezing due to an allergic reaction. Albuterol is a short-acting beta-agonist that helps relieve bronchospasm quickly. Cromolyn is more commonly used for the prevention of asthma symptoms rather than for acute treatment. Methylprednisolone and aminophylline are not the first-line medications for acute wheezing due to an allergic reaction.
What is the first action a healthcare provider should take for a patient with possible acute coronary syndrome?
- A. Administer sublingual nitroglycerin
- B. Get IV access
- C. Auscultate heart sounds
- D. Obtain cardiac enzymes
Correct Answer: A
Rationale: Administering sublingual nitroglycerin is the initial priority action for a patient with possible acute coronary syndrome. Nitroglycerin helps dilate blood vessels, reduce chest pain, and improve blood flow to the heart muscle. This helps in relieving symptoms and preventing further damage to the heart. Establishing IV access, auscultating heart sounds, and obtaining cardiac enzymes are important steps in the assessment and management of acute coronary syndrome but are not the first actions to be taken. IV access may be needed for administering medications or fluids, auscultating heart sounds helps in assessing the heart's function, and obtaining cardiac enzymes aids in diagnosing a heart attack.
What lab value should be prioritized for monitoring in a patient with HIV?
- A. CD4 T-cell count below 180 cells/mm3
- B. Hemoglobin levels
- C. Serum albumin levels
- D. White blood cell count
Correct Answer: A
Rationale: The correct answer is A: CD4 T-cell count below 180 cells/mm3. Monitoring CD4 T-cell count is crucial in patients with HIV as it reflects the status of their immune system. A CD4 count below 200 cells/mm3 is indicative of severe immunocompromise, necessitating close monitoring and potential intervention. Choices B, C, and D are less specific to HIV management and do not directly reflect the immune status in these patients. Hemoglobin levels are more relevant for assessing anemia, serum albumin levels for nutritional status, and white blood cell count for overall immune response, but none are as directly tied to HIV disease progression as the CD4 T-cell count.
What are the expected symptoms in a patient with a thrombotic stroke?
- A. Gradual loss of function on one side of the body
- B. Sudden loss of consciousness
- C. Severe headache and confusion
- D. Loss of sensation in the affected limb
Correct Answer: A
Rationale: A thrombotic stroke typically presents with a gradual loss of function on one side of the body. This gradual onset distinguishes it from a hemorrhagic stroke, which often manifests with sudden and severe symptoms like loss of consciousness (choice B), severe headache and confusion (choice C), or loss of sensation in the affected limb (choice D). Therefore, choices B, C, and D are not typically associated with thrombotic strokes.
A patient experiencing wheezing due to an allergic reaction needs immediate treatment. Which medication should be administered first?
- A. Albuterol via nebulizer
- B. Cromolyn via nebulizer
- C. Aminophylline IV
- D. Methylprednisolone IV
Correct Answer: A
Rationale: The correct answer is A: Albuterol via nebulizer. Albuterol is a rapid-acting bronchodilator that helps relieve wheezing by opening up the airways. During an allergic reaction causing wheezing, prompt relief is crucial, making Albuterol the first-line treatment. Choice B, Cromolyn via nebulizer, is used more for preventing asthma symptoms rather than providing immediate relief. Choice C, Aminophylline IV, is a bronchodilator with a slower onset of action compared to Albuterol. Choice D, Methylprednisolone IV, is a corticosteroid used to reduce inflammation and is not the first-line treatment for acute wheezing in an allergic reaction.
