Correct Answer: B

Rationale: The correct answer is B: Avoiding environmental allergens and smoking. Environmental allergens and smoking are common triggers for asthma attacks. Avoiding these triggers can significantly reduce the risk of exacerbations. Over-the-counter medications may provide symptomatic relief but do not address the underlying triggers. Increasing physical activity can be beneficial but may also trigger asthma attacks in some individuals. Limiting fluid intake to reduce mucus production is not a recommended strategy for managing asthma triggers.

Correct Answer: D

Rationale: The correct answer is D: Huntington's chorea. Huntington's chorea is a genetic disorder characterized by involuntary, writhing, and twisting movements of the face and limbs, known as chorea. This is due to degeneration of certain brain cells. Epilepsy (A) involves seizures, not specific movements. Parkinson's (B) is characterized by tremors and rigidity, not chorea. Multiple sclerosis (C) affects the central nervous system, causing a variety of symptoms, but not typically chorea.

Correct Answer: A

Rationale: The correct answer is A: Administer pain relief. The nurse should address the client's immediate symptom of severe headache to provide comfort and assess the severity of the condition. Pain relief can help decrease anxiety and prevent complications. Monitoring vital signs (B) is important but treating the symptom should take priority. Monitoring ECG (C) is not necessary for a headache presentation. Administering insulin (D) is not indicated for a client presenting with a severe headache.

Correct Answer: C

Rationale: The correct answer is C: Swelling in the legs and shortness of breath. In heart failure, the heart is unable to pump effectively, leading to fluid accumulation in the body. Swelling in the legs (edema) is a classic sign of fluid overload as the fluid pools in the lower extremities. Shortness of breath occurs due to fluid accumulating in the lungs, causing difficulty in breathing. Weight loss and increased appetite (A) are not typical signs of fluid overload. Increased urine output and dehydration (B) are more indicative of fluid deficit. Nausea and vomiting (D) can occur in various conditions but are not specific to fluid overload in heart failure.

Correct Answer: B

Rationale: The correct answer is B because HIPAA regulates the privacy and security of protected health information. This includes how healthcare providers, insurers, and other entities handle and safeguard patient information to ensure confidentiality. Choice A is incorrect as HIPAA does not dictate who provides client care. Choice C is incorrect as HIPAA focuses on the protection of health information, not how insurance information is obtained. Choice D is incorrect as HIPAA does not specify where a chart can be stored, but rather how the information within it is protected.
