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 deep vein thrombosis (DVT) is being treated with warfarin. Which dietary instruction should the nurse provide?

• A. Avoid foods high in vitamin C
• B. Increase intake of green leafy vegetables
• C. Limit intake of foods high in vitamin K
• D. Avoid dairy products

Correct answer: C

Rationale: The correct answer is C: 'Limit intake of foods high in vitamin K'. Vitamin K can interfere with the effectiveness of warfarin, an anticoagulant medication commonly used to treat conditions like deep vein thrombosis (DVT). Patients on warfarin should maintain a consistent intake of vitamin K-rich foods and be monitored closely. Choices A, B, and D are incorrect because avoiding foods high in vitamin C, increasing intake of green leafy vegetables, and avoiding dairy products are not essential dietary instructions for a client on warfarin therapy for DVT.

3. The nurse instructs the mother of a child with a ventricular septal defect that she can expect the child to become cyanotic when the child does what?

• A. Experiences an elevation in temperature.
• B. Sleeps on the left side.
• C. Cries vigorously.
• D. Eats.

Correct answer: C

Rationale: The correct answer is C: Cries vigorously. When the child cries vigorously, it increases the pressure in the right ventricle, allowing unoxygenated blood to enter the circulating volume, leading to cyanosis. This occurs due to the shunting of blood from the right side of the heart to the left side through the ventricular septal defect. Choices A, B, and D are incorrect because they do not directly impact the pressure in the right ventricle, which is crucial in causing cyanosis in this scenario.

4. A client who is newly diagnosed with emphysema is being prepared for discharge. Which instruction is best for the nurse to provide the client to assist them with dyspnea self-management?

• A. Allow additional time to complete physical activities to reduce oxygen demand.
• B. Practice inhaling through the nose and exhaling slowly through pursed lips.
• C. Use a humidifier to increase home air quality humidity between 30-50%.
• D. Strengthen abdominal muscles by alternating leg raises during exhalation.

Correct answer: B

Rationale: The correct answer is B. Instructing the client to practice inhaling through the nose and exhaling slowly through pursed lips can help improve oxygenation and reduce dyspnea. This technique, known as pursed lip breathing, can help regulate breathing patterns and decrease the work of breathing in clients with emphysema. Choice A is incorrect because allowing additional time for physical activities does not directly address dyspnea management. Choice C is incorrect as using a humidifier, although beneficial for respiratory conditions, does not specifically assist with dyspnea self-management. Choice D is also incorrect as strengthening abdominal muscles through leg raises does not directly target dyspnea relief.

5. What is the hallmark sign of intussusception?

• A. Mucus-like stools
• B. Currant jelly-like stools
• C. Tarry, black stools
• D. Green, soft stools

Correct answer: B

Rationale: The hallmark sign of intussusception is currant jelly-like stools, which result from the mixture of blood and mucus in the stool due to the sloughing of intestinal mucosa. Mucus-like stools (Choice A) are not typically associated with intussusception. Tarry, black stools (Choice C) are characteristic of gastrointestinal bleeding higher up in the gastrointestinal tract, such as from a peptic ulcer. Green, soft stools (Choice D) are more indicative of rapid transit through the intestines, possibly due to dietary factors or infections such as gastroenteritis.
