1. What is the priority lab value to monitor in a patient with HIV?

• A. CD4 T-cell count 180 cells/mm3
• B. White blood cell count 4,500/mm3
• C. Potassium levels 3.5-5.0 mEq/L
• D. Hemoglobin levels below 12g/dL

Correct answer: A

Rationale: The correct answer is A: CD4 T-cell count 180 cells/mm3. Monitoring the CD4 T-cell count is crucial in patients with HIV to assess the status of their immune system. A CD4 count of 180 cells/mm3 indicates severe immunocompromise and a high risk of opportunistic infections. This value is used to guide treatment decisions and assess the need for prophylaxis against specific infections. Choices B, C, and D are incorrect because monitoring white blood cell count, potassium levels, and hemoglobin levels, although important in HIV patients, are not as crucial as monitoring the CD4 T-cell count for assessing immune function and disease progression.

2. What is the first-line treatment for wheezing due to an allergic reaction?

• A. Albuterol via nebulizer
• B. Cromolyn 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 because it acts quickly to open the airways by relaxing the muscles in the air passages. Cromolyn (Choice B) is used for asthma prevention rather than acute wheezing. Methylprednisolone (Choice C) and Aminophylline (Choice D) are not the first-line treatments for acute wheezing in the setting of an allergic reaction.

3. 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.

4. 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.

5. A patient who experienced an acute episode of gastritis should avoid which type of foods?

• A. Avoid foods high in potassium
• B. Avoid foods high in sodium
• C. Increase exercise to reduce stress
• D. Drink milk as a snack

Correct answer: A

Rationale: The correct answer is A: Avoid foods high in potassium. Potassium-rich foods can exacerbate gastritis symptoms by irritating the stomach lining. Sodium (choice B) is not directly related to gastritis symptoms. Increasing exercise (choice C) can be beneficial for overall health but may not directly impact gastritis. Drinking milk (choice D) can provide temporary relief for some individuals with gastritis due to its coating effect, but it is not a universal recommendation as it can worsen symptoms in some cases.
