1. What ECG changes should be monitored in a patient with hypokalemia?

A. Flattened T waves and prominent U waves
B. Elevated ST segments and wide QRS complexes
C. Tall T waves and flattened QRS complexes
D. Widened QRS complexes and decreased P wave amplitude

Correct answer: A

Rationale: The correct answer is A: Flattened T waves and prominent U waves. In hypokalemia, there is a decrease in potassium levels, which can lead to ECG changes such as flattened T waves and prominent U waves. These changes are classic findings associated with hypokalemia. Choices B (Elevated ST segments and wide QRS complexes), C (Tall T waves and flattened QRS complexes), and D (Widened QRS complexes and decreased P wave amplitude) are all incorrect. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia. Tall T waves and flattened QRS complexes, as well as widened QRS complexes and decreased P wave amplitude, do not represent the typical ECG changes seen in hypokalemia.

2. What are the priority lab values to monitor in a patient with HIV?

A. CD4 T-cell count below 180 cells/mm3
B. White blood cell count
C. Hemoglobin levels
D. Serum albumin 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 CD4 count below 180 cells/mm3 is considered severe immunocompromise and requires close monitoring and intervention. Choices B, C, and D are not the priority lab values to monitor in HIV patients. While white blood cell count, hemoglobin levels, and serum albumin levels can provide valuable information about the patient's health status, they are not as specific or indicative of HIV disease progression and management as the CD4 T-cell count.

3. What should a healthcare provider teach a patient who has experienced an acute episode of gastritis?

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. During an acute episode of gastritis, it is advisable to avoid foods high in potassium as they can exacerbate symptoms. Potassium-rich foods may irritate the stomach lining, leading to increased discomfort. Choices B, C, and D are incorrect. Avoiding foods high in sodium is not specifically related to managing gastritis. Increasing exercise to reduce stress is a good general recommendation but not directly related to managing gastritis symptoms. Drinking milk as a snack is not recommended for gastritis as dairy products can sometimes worsen symptoms due to their fat content.

4. A nurse is planning care for a patient diagnosed with diabetes insipidus. What should be included in the care plan?

A. Monitor serum albumin levels
B. Restrict protein intake to 0.55-0.60 g/kg/day
C. Encourage the patient to increase fluid intake
D. Teach the patient to avoid alcohol

Correct answer: A

Rationale: The correct answer is to monitor serum albumin levels. In patients with diabetes insipidus, monitoring serum albumin levels is essential to assess for dehydration and nutritional deficits. Choices B, C, and D are not directly related to managing diabetes insipidus. Restricting protein intake, encouraging fluid intake, and teaching the patient to avoid alcohol are interventions that may be relevant for other medical conditions but are not specific to addressing the needs of a patient with diabetes insipidus.

5. What medication should be administered first for wheezing due to an allergic reaction?

A. Albuterol via nebulizer
B. Cromolyn via nebulizer
C. Methylprednisolone IV
D. Aminophylline 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 quickly opens the airways by relaxing the muscles around the airways. Cromolyn (choice B) is used more for prevention rather than immediate relief of symptoms. Methylprednisolone (choice C) and Aminophylline (choice D) are not the first-line treatments for acute wheezing due to an allergic reaction.
