1. What should be the first medication given for wheezing due to an allergic reaction?

• A. Albuterol via nebulizer
• B. Cromolyn via nebulizer
• C. Methylprednisolone IV
• D. Aminophylline 500 mg IV

Correct answer: A

Rationale: The correct answer is A, Albuterol via nebulizer. Albuterol is the first-line medication for treating wheezing caused by an allergic reaction as it works as a bronchodilator, helping to relieve the symptoms of wheezing and shortness of breath quickly. Cromolyn (choice B) is used more for preventing asthma symptoms rather than for immediate relief. Methylprednisolone IV (choice C) and Aminophylline 500 mg IV (choice D) are not the first-line treatments for wheezing due to an allergic reaction.

2. What is the priority action for a patient experiencing chest pain from acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Obtain IV access
• C. Check the patient's cardiac enzymes
• D. Administer aspirin

Correct answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. Nitroglycerin helps relieve chest pain by dilating blood vessels and improving blood flow to the heart, which is crucial in managing acute coronary syndrome. While obtaining IV access and checking cardiac enzymes are important steps in the assessment and management of acute coronary syndrome, administering nitroglycerin takes precedence to alleviate symptoms and reduce cardiac tissue damage. Administering aspirin is also essential in the treatment of acute coronary syndrome, but it is not the immediate priority in this scenario.

3. What are the expected ECG changes in hypokalemia?

• A. Flattened T waves
• B. ST elevation
• C. Wide QRS complex
• D. Tall T waves

Correct answer: A

Rationale: Flattened T waves are the most common ECG change seen in patients with hypokalemia. Hypokalemia leads to a decrease in serum potassium levels, affecting the repolarization phase of the cardiac action potential. This results in T wave flattening or inversion. ST elevation is typically seen in conditions like myocardial infarction, not in hypokalemia. Wide QRS complex is more associated with hyperkalemia than hypokalemia. Tall T waves are often seen in hyperkalemia, not hypokalemia.

4. What is the priority action for a patient with chest pain from acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Check the patient's cardiac enzymes
• C. Administer aspirin
• D. Obtain IV access

Correct answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. This medication helps dilate the blood vessels, reducing the workload of the heart and improving blood flow to the heart muscle, which is crucial in the management of acute coronary syndrome. Checking cardiac enzymes (choice B) is important for diagnosing a heart attack but is not the priority over providing immediate relief to the patient's chest pain. Administering aspirin (choice C) is also important in acute coronary syndrome to prevent further clot formation, but it is not the priority action for immediate pain relief. Obtaining IV access (choice D) is necessary for administering medications or fluids; however, in this scenario, providing sublingual nitroglycerin for prompt pain relief takes precedence.

5. What lab value should be prioritized in a patient with HIV?

• A. CD4 T-cell count below 180 cells/mm3
• B. White blood cell count
• C. Serum albumin levels
• D. Hemoglobin levels

Correct answer: A

Rationale: The correct answer is A: CD4 T-cell count below 180 cells/mm3. Monitoring the CD4 T-cell count is crucial in patients with HIV as it indicates the level of immunocompromise. A count below 180 cells/mm3 signifies severe immunocompromise and an increased risk of opportunistic infections. Choices B, C, and D are not the priority lab values in HIV management. While white blood cell count, serum albumin levels, and hemoglobin levels are important, they do not directly reflect the immune status and progression of HIV as the CD4 T-cell count does.
