Correct Answer: D

Rationale: During a tonic-clonic seizure, the nurse's priority intervention is to protect the client's head from injury. This is crucial to prevent trauma, as head injuries can be severe during a seizure. Inserting an oral airway may cause injury or obstruction during the seizure and is not recommended. Administering oxygen via nasal cannula can be done after ensuring the client's safety. Restraining the client's arms and legs is also not recommended as it can lead to further injury or harm.

Correct Answer: B

Rationale: The best activity for the nurse to assign to the unlicensed assistive personnel (UAP) in this situation is to provide perianal care and collect clean linens for the dressing change. This task is crucial to maintain proper hygiene, prevent infection, and promote healing in the areas affected by decubiti. Choice A is not the priority as addressing the contamination and ensuring hygiene is more critical. Choice C is not the immediate concern and does not address the current situation. Choice D involves direct client care tasks that should be handled by licensed nursing staff.

Correct Answer: D

Rationale: The correct answer is 'Wear long sleeves and pants.' This instruction is crucial in reducing the risk of Lyme disease because it helps minimize exposure to ticks that carry the disease. Ticks are commonly found in grassy and wooded areas, so covering up with long sleeves and pants can act as a physical barrier and prevent ticks from attaching to the skin. Choices A, B, and C are not directly related to preventing Lyme disease. Washing hands frequently is important for general hygiene but not specifically for preventing tick bites. Avoiding drinking lake water is more about preventing waterborne illnesses rather than Lyme disease. Not sharing personal products is important for preventing the spread of infections but is not directly related to Lyme disease prevention.

Correct Answer: A

Rationale: Muscle weakness is a common finding in clients with hyperkalemia. Hyperkalemia can lead to muscle weakness due to the effect of high potassium levels on muscle function. Decreased deep tendon reflexes (Choice B) are not typically associated with hyperkalemia; instead, hyperreflexia or increased reflexes may be observed. Constipation (Choice C) is not a common symptom of hyperkalemia. Hypotension (Choice D) is also not a typical finding in hyperkalemia; instead, hypertension or normal blood pressure may be present.
