Nursing Elites

1. 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.

2. Which ECG change is associated with hyperkalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. Elevated ST segments
• D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are a characteristic ECG change seen in hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac cycle, leading to T wave abnormalities. Prominent U waves are typically seen in hypokalemia. Elevated ST segments are more indicative of myocardial infarction or pericarditis. Widened QRS complexes are commonly associated with conditions like bundle branch blocks or certain toxicities.

3. What ECG changes are seen in hypokalemia?

• A. Flattened T waves on the ECG
• B. Elevated ST segments on the ECG
• C. Widened QRS complex
• D. Prominent U waves on the ECG

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on the ECG. Flattened T waves are an early indicator of hypokalemia on an ECG. Choice B, Elevated ST segments, is not typically seen in hypokalemia but can be a sign of myocardial infarction. Choice C, Widened QRS complex, is more commonly associated with hyperkalemia. Choice D, Prominent U waves, is typically associated with hypokalemia, but flattened T waves are considered a more specific and early sign.

4. 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.

5. What intervention should the nurse take for a patient experiencing delayed wound healing?

• A. Monitor serum albumin levels
• B. Apply a dry dressing
• C. Administer antibiotics
• D. Change the wound dressing every 8 hours

Correct answer: A

Rationale: Monitoring serum albumin levels is crucial for patients with delayed wound healing. Low albumin levels indicate a lack of protein, which can impair the healing process and increase the risk of infection. By monitoring serum albumin levels, the nurse can assess the patient's nutritional status and make necessary interventions to promote wound healing. Applying a dry dressing (Choice B) may be appropriate depending on the wound characteristics, but it does not address the underlying cause of delayed healing. Administering antibiotics (Choice C) is not the first-line intervention for delayed wound healing unless there is an active infection present. Changing the wound dressing every 8 hours (Choice D) may lead to excessive disruption of the wound bed and hinder the healing process.
