Nursing Elites

1. Which of the following is reflected in an ECG due to hypokalemia?

• A. Tall T waves and Pathologic Q wave
• B. Widening QRS Complex and U wave
• C. None of the above
• D. Both A and B

Correct answer: B

Rationale: Hypokalemia, a condition characterized by low levels of potassium in the blood, is reflected in an ECG by a widening QRS Complex and a U wave. This is because potassium plays a key role in the electrical activity of the heart, and its deficiency can lead to abnormalities in the heart's rhythm as represented by these specific changes on the ECG. Choice A is incorrect as tall T waves and pathologic Q waves are more commonly associated with hyperkalemia or myocardial infarction, respectively, rather than hypokalemia. Choices C and D are also incorrect as they do not accurately reflect the ECG changes caused by hypokalemia.

2. A nurse is providing dietary teaching for a client who has just learned that she has type 2 diabetes mellitus. The nurse should explain that which of the following sweeteners will add calories to the client's carbohydrate count?

• A. Sorbitol
• B. Sucralose
• C. Aspartame
• D. Acesulfame potassium

Correct answer: A

Rationale: Sorbitol is a sweetener that will add calories to the client's carbohydrate count. It is a sugar alcohol that provides about 2.6 calories per gram. Sucralose, aspartame, and acesulfame potassium are all non-nutritive sweeteners that do not contribute significant calories to the diet. Sucralose is about 600 times sweeter than sucrose but does not add calories. Aspartame is a low-calorie sweetener that is approximately 200 times sweeter than sucrose, and acesulfame potassium is a calorie-free sweetener.

3. A nurse is providing teaching to a group of adult athletes about preventing the effects of dehydration on the body. Which of the following manifestations should the nurse include in the teaching?

• A. Impaired motor control
• B. Drop in body temperature during exercise
• C. Increase in appetite
• D. Decreased resting heart rate

Correct answer: A

Rationale: Dehydration can lead to impaired motor control due to electrolyte imbalances affecting muscle function. Choices B, C, and D are incorrect. Dehydration typically causes an increase in body temperature during exercise, not a drop. Dehydration is more likely to suppress appetite, leading to a decrease rather than an increase in appetite. Also, dehydration often results in an increased heart rate rather than a decreased resting heart rate.

4. Angie is a disoriented client who frequently falls from the bed. As her nurse, which of the following is the best nursing intervention to prevent future falls?

• A. Tell Angie not to get up from bed unassisted
• B. Put the call bell within her reach
• C. Put bedside commode at the bedside to prevent Angie from getting up
• D. Put the bed in the lowest position ever

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

5. Hypertrophic burn scars are caused by:

• A. exaggerated contraction
• B. random layering of collagen
• C. wound ischemia
• D. delayed epithelialization

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
