Nursing Elites

1. Based on this strip, what is the interpretation of this rhythm?

• A. Atrial fibrillation.
• B. Ventricular tachycardia.
• C. Normal sinus rhythm.
• D. Second-degree heart block.

Correct answer: C

Rationale: The correct answer is C, Normal sinus rhythm. Normal sinus rhythm is characterized by a regular rhythm, normal P waves, and a consistent PR interval. In this context, the strip likely shows a normal ECG pattern with these characteristics, indicating a healthy heart rhythm. Choices A, B, and D are incorrect. Atrial fibrillation would show an irregularly irregular rhythm with no discernible P waves. Ventricular tachycardia would display wide QRS complexes and a fast heart rate. Second-degree heart block would exhibit intermittent dropped QRS complexes.

2. A client with rheumatoid arthritis is prescribed methotrexate. Which instruction should the nurse include in the teaching plan?

• A. Avoid taking folic acid supplements
• B. Report any signs of infection immediately
• C. Limit fluid intake to prevent edema
• D. Increase intake of high-calcium foods

Correct answer: B

Rationale: The correct instruction that the nurse should include in the teaching plan for a client prescribed methotrexate is to report any signs of infection immediately. Methotrexate can suppress the immune system, making the individual more susceptible to infections. Reporting signs of infection promptly allows for timely intervention. Choices A, C, and D are incorrect. Avoiding folic acid supplements is not recommended because methotrexate can lead to folate deficiency, so supplementation may be necessary. There is no direct correlation between fluid intake limitation and methotrexate use. Increasing high-calcium foods is not specifically related to methotrexate therapy for rheumatoid arthritis.

3. A client admitted with left-sided heart failure has a heart rate of 110 beats per minute and is becoming increasingly dyspneic. Which additional assessment finding by the nurse supports the client’s admitting diagnosis?

• A. Jugular vein distention.
• B. Crackles in the lung bases.
• C. Peripheral edema.
• D. Bounding peripheral pulses.

Correct answer: B

Rationale: The correct answer is B: Crackles in the lung bases. Crackles in the lung bases are indicative of pulmonary congestion, which is a classic sign of left-sided heart failure. Left-sided heart failure leads to a backup of blood into the lungs, causing fluid leakage into the alveoli and resulting in crackles upon auscultation. Choices A, C, and D are less specific to left-sided heart failure. Jugular vein distention can be seen in right-sided heart failure, peripheral edema can be seen in both right and left-sided heart failure, and bounding peripheral pulses are more indicative of conditions like hyperthyroidism or anemia rather than specifically supporting left-sided heart failure.

4. Which instruction should be included in the discharge teaching plan for a client who has had a cataract extraction today?

• A. Use a metal eye shield on the operative eye during the day.
• B. Administer eye ointment after applying eye drops.
• C. Light housekeeping is safe to do, but avoid heavy lifting.
• D. Refrain from sexual activities until follow-up appointment.

Correct answer: C

Rationale: The correct instruction to include in the discharge teaching plan for a client who has had a cataract extraction is that light housekeeping is safe to do, but heavy lifting should be avoided to prevent increased intraocular pressure. Choice A is incorrect as the eye shield is usually worn at night to protect the eye. Choice B is incorrect as eye ointment is usually applied after eye drops to avoid washing away the ointment. Choice D is incorrect as sexual activities should be avoided until the follow-up appointment to prevent complications.

5. A client with hyperkalemia is being treated in the emergency department. Which medication should the nurse prepare to administer?

• A. Potassium chloride
• B. Calcium gluconate
• C. Magnesium sulfate
• D. Sodium bicarbonate

Correct answer: B

Rationale: The correct answer is B, Calcium gluconate. In hyperkalemia, where potassium levels are elevated, calcium gluconate is administered to stabilize the myocardial cell membrane and protect the heart from potential arrhythmias. Potassium chloride (choice A) would worsen the condition by further increasing potassium levels. Magnesium sulfate (choice C) is not the primary treatment for hyperkalemia. Sodium bicarbonate (choice D) is used in metabolic acidosis, not specifically for hyperkalemia.
