1. What precaution should be advised to patients following cataract surgery?

• A. Wear dark glasses while outdoors
• B. Use warm compresses
• C. Avoid NSAIDs
• D. Avoid bright lights

Correct answer: A

Rationale: Patients who have undergone cataract surgery should wear dark glasses when outdoors to shield their eyes from light exposure, which can be uncomfortable or harmful during the recovery period. Using warm compresses (choice B) is not typically recommended after cataract surgery as it's more relevant for certain eye conditions. Avoiding NSAIDs (choice C) is advised to prevent bleeding complications, but it is not directly related to eye protection post-surgery. While avoiding bright lights (choice D) is crucial, wearing dark glasses provides a practical solution to achieve this, making choice A the most appropriate precaution.

2. 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.

3. What is the first medication to give to a patient with an allergic reaction causing wheezing?

• A. Albuterol 3 ml via nebulizer
• B. Methylprednisolone 100 mg IV
• C. Cromolyn 20 mg via nebulizer
• D. Aminophylline 500 mg IV

Correct answer: A

Rationale: The correct answer is A, Albuterol 3 ml via nebulizer. Albuterol is a fast-acting bronchodilator that helps relieve wheezing by relaxing the muscles in the airways, making it the first-line treatment for wheezing caused by bronchospasms in allergic reactions. Methylprednisolone (Choice B) is a corticosteroid used for its anti-inflammatory properties and is typically given after bronchodilators. Cromolyn (Choice C) is a mast cell stabilizer that is used for the prevention of asthma symptoms, not for immediate relief. Aminophylline (Choice D) is a bronchodilator that is less commonly used nowadays due to its narrow therapeutic window and potential for toxicity.

4. A healthcare professional is preparing a client for a colonoscopy. Which of the following medications should the professional anticipate the provider to prescribe as an anesthetic for the procedure?

• A. Propofol
• B. Pancuronium
• C. Promethazine
• D. Pentoxifylline

Correct answer: A

Rationale: The correct answer is A, Propofol. Propofol is a short-acting anesthetic medication commonly used for procedures like colonoscopies to induce moderate sedation. Pancuronium (Choice B) is a neuromuscular blocking agent used as a paralyzing agent during surgery, not for sedation. Promethazine (Choice C) is an antihistamine often used for nausea and vomiting, not as an anesthetic. Pentoxifylline (Choice D) is a medication used to improve blood flow and is not indicated for anesthesia.

5. What is the first medication to give to a patient experiencing 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: The correct answer is A, Albuterol via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction due to its rapid action in opening airways. Cromolyn (Choice B) is used for prevention rather than acute treatment. Methylprednisolone (Choice C) and Aminophylline (Choice D) are not the first-line treatments for acute wheezing in allergic reactions.
