Nursing Elites

1. What are the expected findings in a patient experiencing hypokalemia?

• A. Flattened T waves on an ECG
• B. Elevated ST segments
• C. Prominent U waves
• D. Bradycardia

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on an ECG. Hypokalemia is characterized by flattened T waves on an ECG, which is an early indicator of low potassium levels. Elevated ST segments (Choice B) are associated with conditions like myocardial infarction, not hypokalemia. Prominent U waves (Choice C) are typically seen in hypokalemia, but flattened T waves are more specific. Bradycardia (Choice D) can be a manifestation of severe hypokalemia but is not as specific as flattened T waves on an ECG.

2. A nurse is providing discharge teaching for a client who has COPD about nutrition. Which of the following instructions should the nurse include?

• A. Eat three large meals daily
• B. Consume high-calorie foods
• C. Limit caffeinated drinks to two per day
• D. Drink fluids during meal time

Correct answer: B

Rationale: The correct answer is B: 'Consume high-calorie foods.' Clients with COPD often have increased energy needs due to the work of breathing. Consuming high-calorie, high-protein foods can help provide the necessary energy and prevent weight loss. Choice A is incorrect because eating three large meals daily may lead to increased shortness of breath due to a full stomach putting pressure on the diaphragm. Choice C is incorrect because caffeinated drinks can contribute to dehydration, which is not ideal for clients with COPD. Choice D is incorrect because drinking fluids during mealtime can cause bloating and early satiety, making it difficult for clients to consume enough calories.

3. 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.

4. A client at high risk for iron deficiency anemia should increase the consumption of which of the following foods?

• A. Yogurt
• B. Apples
• C. Raisins
• D. Cheddar cheese

Correct answer: C

Rationale: The correct answer is C: Raisins. Raisins are a good source of iron, making them beneficial for a client at high risk for iron deficiency anemia. Yogurt (Choice A), apples (Choice B), and cheddar cheese (Choice D) are not significant sources of iron. Other iron-rich foods include dried fruits, red meat, and green leafy vegetables.

5. What ECG changes are expected in hypokalemia?

• A. Flattened T waves on ECG
• B. Prominent U waves on ECG
• C. Widened QRS complexes on ECG
• D. ST elevation on ECG

Correct answer: A

Rationale: In hypokalemia, flattened T waves are a common ECG finding due to the decreased extracellular potassium affecting repolarization. Prominent U waves are typically seen in hypokalemia as well, but flattened T waves are the more specific and early ECG change. Widened QRS complexes are associated with hyperkalemia, not hypokalemia. ST elevation is often seen in conditions like myocardial infarction, pericarditis, or early repolarization syndrome, not specifically in hypokalemia.
