What should a healthcare provider monitor for in a patient with HIV and a CD4 T-cell count below 180 cells/mm3?
- A. Monitor for signs of infection
- B. Monitor for anemia
- C. Monitor for dehydration
- D. Monitor for bleeding
Correct Answer: A
Rationale: A CD4 T-cell count below 180 cells/mm3 indicates severe immunocompromise in a patient with HIV. Monitoring for signs of infection is crucial because the patient is at high risk of developing opportunistic infections. Anemia (choice B), dehydration (choice C), and bleeding (choice D) are not directly associated with a low CD4 T-cell count in patients with HIV.

What is the first medication to administer for a patient experiencing wheezing due to an allergic reaction?
- A. Albuterol 3 ml 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 3 ml via nebulizer. Albuterol is the first-line medication for wheezing due to its rapid bronchodilatory effects. Choice B, Cromolyn, is used more for preventing allergic reactions rather than acute relief of wheezing. Choice C, Methylprednisolone, is a steroid used for its anti-inflammatory effects and is not the initial choice for acute relief of wheezing. Choice D, Aminophylline, is a bronchodilator but is not the first-line treatment for wheezing due to allergic reactions.
What is an escharotomy, and why is it performed?
- A. To relieve pressure and improve circulation in burn injuries
- B. To reduce pain in the affected area
- C. To remove necrotic tissue from a wound
- D. To remove fluid from a burn wound
Correct Answer: A
Rationale: An escharotomy is a surgical procedure performed to relieve pressure and improve circulation in areas affected by deep burns. Choice A is the correct answer because the primary goal of an escharotomy is to prevent compartment syndrome caused by increased pressure within the affected tissues. Choices B, C, and D are incorrect because an escharotomy is not primarily performed to reduce pain, remove necrotic tissue, or drain fluid from a burn wound, but to address the specific issue of compromised blood flow and pressure within deep burn injuries.
What dietary instructions should be provided for a patient with pre-dialysis end-stage kidney disease?
- A. Limit phosphorus intake to 700 mg/day
- B. Increase protein intake to 1g/kg/day
- C. Increase sodium intake
- D. Avoid potassium-rich foods
Correct Answer: A
Rationale: Patients with pre-dialysis end-stage kidney disease should limit phosphorus intake to manage their condition. Excessive phosphorus can lead to mineral and bone disorders in patients with kidney disease. Choices B, C, and D are incorrect. Increasing protein intake is not recommended as it can burden the kidneys. Increasing sodium intake is usually discouraged due to its association with hypertension and fluid retention in kidney disease. Avoiding potassium-rich foods is more relevant in advanced kidney disease stages when potassium levels are high, not in pre-dialysis end-stage kidney disease.
What is the first medication to give to a patient with wheezing due to an allergic reaction?
- A. Albuterol 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 via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction because it is a fast-acting bronchodilator that helps to quickly open the airways, providing immediate relief of symptoms. Choice B, Methylprednisolone 100 mg IV, is a corticosteroid used for its anti-inflammatory effects but is not the initial medication for acute wheezing in an allergic reaction. Choice C, Cromolyn 20 mg via nebulizer, is a mast cell stabilizer that can be used for prevention but is not the first choice for acute symptom relief. Choice D, Aminophylline 500 mg IV, is a bronchodilator with a narrow therapeutic window and more side effects compared to Albuterol, making it a less preferred option as the initial treatment.
What is the first intervention for a patient admitted with unstable angina?
- A. Administer nitroglycerin
- B. Obtain cardiac enzymes
- C. Start IV fluids
- D. Monitor for chest pain
Correct Answer: A
Rationale: The correct first intervention for a patient admitted with unstable angina is to administer nitroglycerin. Nitroglycerin helps to relieve chest pain by dilating blood vessels and increasing blood flow to the heart, thereby reducing cardiac workload. This intervention aims to alleviate symptoms and prevent further cardiac damage. Obtaining cardiac enzymes (Choice B) is important for diagnosing a myocardial infarction but is not the initial intervention for unstable angina. Starting IV fluids (Choice C) may be indicated in specific cases like hypovolemia but is not the primary intervention for unstable angina. Monitoring for chest pain (Choice D) is essential but taking action to alleviate the pain, like administering nitroglycerin, is the primary focus in the initial management of unstable angina.
