Nursing Elites

1. A nurse is reviewing the laboratory results of a client who has hypokalemia. Which of the following findings should the nurse expect?

• A. Serum potassium 5.4 mEq/L
• B. Flat T waves
• C. Elevated ST segments
• D. Bradycardia

Correct answer: B

Rationale: Flat T waves are a characteristic ECG finding in hypokalemia. Hypokalemia causes a decrease in serum potassium levels, leading to altered cardiac conduction. Flat T waves are associated with hypokalemia-induced cardiac dysrhythmias. Elevated ST segments are typically seen in conditions like myocardial infarction, not in hypokalemia. Bradycardia is not a typical manifestation of hypokalemia; instead, tachycardia may occur due to potassium imbalances affecting the heart's electrical activity.

2. A nurse is reviewing the medical history of a client who has angina. What risk factor should the nurse identify?

• A. Hyperlipidemia.
• B. COPD.
• C. Seizure disorder.
• D. Hyponatremia.

Correct answer: A

Rationale: The correct answer is A, Hyperlipidemia. Hyperlipidemia, characterized by high levels of lipids in the blood, is a well-established risk factor for the development of angina. Elevated lipid levels can lead to atherosclerosis, which narrows the arteries supplying the heart muscle with oxygenated blood, increasing the risk of angina. Choices B, C, and D are incorrect because COPD, seizure disorder, and hyponatremia are not directly associated with an increased risk of angina.

3. A nurse is reviewing the plan of care for a client who is in the manic phase of bipolar disorder. Which of the following interventions should the nurse expect to include?

• A. Encourage group activities to promote socialization.
• B. Encourage the client to take frequent naps throughout the day.
• C. Provide the client with frequent high-calorie snacks.
• D. Promote physical activity during mealtimes to stimulate appetite.

Correct answer: C

Rationale: Providing high-calorie snacks is essential when caring for a client in the manic phase of bipolar disorder because they often have increased energy expenditure and may not eat adequately due to their heightened activity levels. Encouraging group activities (Choice A) may overwhelm the client further during this phase. Encouraging frequent naps (Choice B) contradicts the need to manage increased energy levels. Promoting physical activity during mealtimes (Choice D) may not be appropriate as it can distract the client from eating, which is crucial in meeting their nutritional needs.

4. A nurse is caring for a 5-month-old infant who has manifestations of severe dehydration and a prescription for parenteral fluid therapy. The guardian asks, 'What are the indications that my baby needs an IV?' Which of the following responses should the nurse make?

• A. Your baby needs an IV because she is not producing any tears
• B. Your baby needs an IV because her fontanels are bulging
• C. Your baby needs an IV because she is breathing slower than normal
• D. Your baby needs an IV because her heart rate is decreasing

Correct answer: A

Rationale: The correct answer is A. A lack of tear production is a sign of severe dehydration in infants, indicating the need for IV therapy. Option B, bulging fontanels, is a sign of increased intracranial pressure, not dehydration. Option C, breathing slower than normal, and Option D, decreasing heart rate, are not specific signs of severe dehydration that would indicate the need for IV therapy in this case.

5. A nurse is reviewing the laboratory results of a client who has heart failure. Which of the following findings should the nurse report to the provider?

• A. Potassium 4.0 mEq/L
• B. Hemoglobin 12 g/dL
• C. BUN 18 mg/dL
• D. Sodium 137 mEq/L

Correct answer: B

Rationale: The correct answer is B: Hemoglobin 12 g/dL. In a client with heart failure, a decrease in hemoglobin levels can indicate anemia, which can exacerbate heart failure symptoms. Reporting this finding to the provider is crucial for appropriate management. Choice A, Potassium 4.0 mEq/L, is within the normal range (3.5-5.0 mEq/L) and does not typically require immediate reporting. Choice C, BUN 18 mg/dL, and Choice D, Sodium 137 mEq/L, are also within normal ranges and not directly related to heart failure management. Therefore, the hemoglobin level is the most critical finding to report in this scenario.
