Nursing Elites

1. A nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.4 mEq/L. Which of the following would the nurse expect to note on the electrocardiogram as a result of the laboratory value?

• A. ST depression
• B. Inverted T wave
• C. Prominent U wave
• D. Tall peaked T waves

Correct answer: D

Rationale: The correct answer is 'Tall peaked T waves.' Tall peaked T waves are characteristic ECG changes associated with hyperkalemia. In hyperkalemia, the elevated potassium levels affect the myocardium, leading to changes in the ECG. ST depression (Choice A) is more commonly associated with myocardial ischemia or infarction. Inverted T wave (Choice B) is seen in conditions like myocardial ischemia or CNS events. Prominent U wave (Choice C) is typically associated with hypokalemia or certain medications. Therefore, in this scenario, the nurse would expect to note tall peaked T waves on the electrocardiogram due to the elevated potassium level.

2. Diabetes insipidus is the result of:

• A. A diet high in sugar and carbohydrates.
• B. A complicated pregnancy.
• C. A disorder of the pancreas.
• D. A disorder of the pituitary gland.

Correct answer: D

Rationale: Diabetes insipidus is caused by a disorder of the pituitary gland affecting ADH regulation. This disorder results in the decreased production or release of antidiuretic hormone (ADH), leading to the inability of the kidneys to concentrate urine properly. Choices A, B, and C are incorrect as they do not relate to the underlying cause of diabetes insipidus.

3. A nurse working in the emergency department is assessing several clients. Which of the following clients is the highest priority?

• A. A client who reports right-sided flank pain and is diaphoretic
• B. A client who has active bleeding from a puncture wound of the left groin area
• C. A client who has a raised red skin rash on his arms, neck, and face
• D. A client who reports shortness of breath and left neck and shoulder pain

Correct answer: D

Rationale: The correct answer is D because shortness of breath with referred pain may indicate a serious condition, such as a cardiac event or pulmonary embolism, making this the highest priority. Option A, flank pain with diaphoresis, could suggest kidney-related issues but is not as immediately life-threatening as compromised breathing. Option B, active bleeding, though serious, can usually be controlled with proper interventions. Option C, a raised red skin rash, may indicate an allergic reaction but is not as urgent as respiratory distress with neck and shoulder pain.

4. Which anatomic malformations are associated with Tetralogy of Fallot?

• A. A sub-aortic septal defect, an overriding aorta, left ventricular hypertrophy, and right ventricular outflow
• B. A sub-aortic septal defect, an overriding aorta, right ventricular hypertrophy, and left ventricular outflow
• C. A sub-aortic septal defect, an overriding aorta, pulmonary atresia, and right ventricular outflow
• D. A sub-aortic septal defect, an overriding aorta, right ventricular hypertrophy, and right ventricular outflow

Correct answer: D

Rationale: Tetralogy of Fallot is characterized by a combination of four heart defects: a sub-aortic septal defect, an overriding aorta, right ventricular hypertrophy, and right ventricular outflow obstruction. This leads to mixing of oxygen-poor and oxygen-rich blood, resulting in cyanosis. Therefore, the correct answer is D. Choices A, B, and C are incorrect because they do not accurately describe the specific combination of anatomic malformations seen in Tetralogy of Fallot.

5. A client with DM has an above-knee amputation because of severe peripheral vascular disease. Two days following surgery, when preparing the client for dinner, what is the nurse's primary responsibility?

• A. Check the client's serum glucose level
• B. Assist the client out of bed to the chair
• C. Place the client in a high-Fowler's position
• D. Ensure that the client's residual limb is elevated

Correct answer: A

Rationale: The correct answer is to check the client's serum glucose level. In a client with diabetes who just had surgery, monitoring the serum glucose level is crucial to ensure proper management of the condition. This helps in preventing complications related to blood sugar fluctuations. Assisting the client out of bed may be important but not the primary responsibility at this time. Placing the client in a high-Fowler's position or ensuring the residual limb is elevated are important interventions for comfort and circulation but are not the primary concern in this scenario.
