Nursing Elites

1. What are the expected ECG findings in hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. Elevated ST segments
• D. Wide QRS complex

Correct answer: A

Rationale: Flattened T waves are the classic ECG finding in hypokalemia. Hypokalemia primarily affects the repolarization phase of the cardiac action potential, leading to T wave abnormalities. While prominent U waves are typically associated with hypokalemia as well, flattened T waves are the most specific and sensitive ECG abnormality seen in hypokalemia. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia and are more indicative of other electrolyte imbalances or cardiac conditions.

2. What is the priority intervention for a patient with unstable angina?

• A. Administer nitroglycerin
• B. Establish IV access
• C. Auscultate heart sounds
• D. Administer aspirin

Correct answer: A

Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient with unstable angina as it helps dilate blood vessels, improve blood flow to the heart, relieve chest pain, and prevent further cardiac damage. Establishing IV access (choice B) may be important but is not the priority over administering nitroglycerin in this scenario. Auscultating heart sounds (choice C) and administering aspirin (choice D) are also important aspects of managing unstable angina, but they are not the immediate priority intervention when a patient is experiencing chest pain.

3. A patient with a new diagnosis of diabetes insipidus is planning care. What should be included in the plan of care?

• A. Avoid alcohol
• B. Increase exercise to reduce stress
• C. Increase fluid intake
• D. Restrict sodium intake

Correct answer: A

Rationale: The correct answer is to avoid alcohol. In diabetes insipidus, excessive urination leads to fluid loss, so it is essential to avoid alcohol which can exacerbate dehydration. Choice B is incorrect as increasing exercise may not directly impact diabetes insipidus. Choice C is also incorrect because although increasing fluid intake may seem intuitive, it is not the primary concern in managing diabetes insipidus. Choice D is not directly related to managing diabetes insipidus; sodium restriction is more relevant in conditions like hypertension or heart failure.

4. What is the appropriate electrical intervention for a patient with ventricular tachycardia and a pulse?

• A. Defibrillation
• B. Synchronized cardioversion
• C. Pacing
• D. Medication administration

Correct answer: B

Rationale: Synchronized cardioversion is the correct electrical intervention for a patient with ventricular tachycardia and a pulse. This procedure delivers a synchronized electrical shock to the heart during a specific phase of the cardiac cycle, aiming to restore the heart's normal rhythm. Defibrillation (choice A) is used for pulseless ventricular tachycardia or ventricular fibrillation. Pacing (choice C) is typically used for bradycardias or certain types of heart blocks. Medication administration (choice D) may be used in some cases, but in the scenario of ventricular tachycardia with a pulse, synchronized cardioversion is the preferred intervention.

5. A nurse is providing teaching to a client who was newly diagnosed with nephrotic syndrome. Which of the following statements should indicate to the nurse that the client understands the teaching?

• A. I can expect swelling in my hands and on my face.
• B. The amount of protein in my blood is high.
• C. I might have some pain and gas in my stomach from this condition.
• D. I will use a soft bristle toothbrush to prevent bleeding gums.

Correct answer: A

Rationale: The correct answer is A. Nephrotic syndrome leads to edema, especially of the face and dependent areas, due to the loss of protein in the urine. Choice B is incorrect because nephrotic syndrome leads to protein loss in the urine, not an increase in blood protein levels. Choice C is incorrect as stomach pain and gas are not typical symptoms of nephrotic syndrome. Choice D is incorrect as using a soft bristle toothbrush is not directly related to the manifestations of nephrotic syndrome.
