Nokea
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.

What is a causative factor of Hirschsprung disease?
- A. Frequent evacuation of solids, liquid, and gases
- B. Excessive peristaltic movement
- C. The absence of parasympathetic ganglion cells in a portion of the colon
- D. One portion of the bowel telescoping into another
Correct Answer: C
Rationale: The correct answer is C: The absence of parasympathetic ganglion cells in a portion of the colon is a causative factor of Hirschsprung disease. This absence leads to the inability of the affected segment of the colon to relax, causing a functional obstruction. Choices A, B, and D are incorrect. Frequent evacuation of solids, liquid, and gases, excessive peristaltic movement, and one portion of the bowel telescoping into another are not causative factors of Hirschsprung disease.
An adolescent female asks the nurse about taking retinoic acid (Accutane). What guidance should be provided by the nurse?
- A. The medication should be used for 10 weeks only.
- B. The medication requires that sexually active females use contraception.
- C. The medication lowers hemoglobin levels very quickly.
- D. The medication has few side effects.
Correct Answer: B
Rationale: The correct guidance the nurse should provide is that sexually active females must use contraception while taking Accutane and for 1 month after the 20 weeks it is prescribed. Choice A is incorrect because Accutane is typically taken for a longer duration than 10 weeks. Choice C is incorrect because Accutane does not lower hemoglobin levels quickly. Choice D is incorrect as Accutane is known for having many side effects, including the risk of birth defects.
During the initial assessment of an older male client with obesity and diabetes who develops intermittent claudication, which additional information obtained by the nurse is most significant?
- A. Smokes 1.5 packs of cigarettes daily.
- B. Exercises regularly.
- C. Has a high-fat diet.
- D. Consumes alcohol daily.
Correct Answer: A
Rationale: The correct answer is A: 'Smokes 1.5 packs of cigarettes daily.' Smoking is a significant risk factor for peripheral arterial disease, a condition that can lead to intermittent claudication. The nicotine and other chemicals in cigarettes can damage blood vessels, leading to reduced blood flow and increased risk of developing circulation problems. Choices B, C, and D are less significant in the context of intermittent claudication. Regular exercise, a high-fat diet, and daily alcohol consumption may have health implications, but they are not as directly linked to the development of intermittent claudication in the presence of obesity, diabetes, and smoking.
A young client who is being taught how to use an inhaler for symptoms of asthma tells the nurse about the intention to use the inhaler but plans to continue smoking cigarettes. In evaluating the client's response, what is the best initial action by the nurse?
- A. Explain the risks of smoking with asthma.
- B. Revise the plan of care.
- C. Encourage the client to reduce smoking gradually.
- D. Provide resources for smoking cessation.
Correct Answer: B
Rationale: The best initial action by the nurse is to revise the plan of care. This is necessary to address the client's intention to continue smoking and ensure that appropriate support and education are provided. Choice A is not the best initial action as the client is already aware of the risks of smoking with asthma. Choice C might not be effective as the client's intention to continue smoking poses a significant risk to their health. Choice D, providing resources for smoking cessation, is important but revising the plan of care should come first to address the immediate concern.
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.
