Correct Answer: A

Rationale: Hyperkalemia is a common complication in chronic kidney disease due to the kidneys' reduced ability to excrete potassium. As kidney function declines, potassium levels may increase, leading to hyperkalemia. Hypernatremia (increased sodium levels), hypocalcemia (low calcium levels), and hyperphosphatemia (elevated phosphate levels) are not typically associated with chronic kidney disease. Therefore, the correct answer is hyperkalemia.

Correct Answer: B

Rationale: Age is a nonmodifiable risk factor for atherosclerosis because it is a natural part of the aging process. While lifestyle factors such as diabetes, exercise level, and dietary preferences can be modified to reduce the risk of atherosclerosis, age cannot be altered. Therefore, age is the correct answer. Diabetes, exercise level, and dietary preferences can all be improved or managed through interventions and lifestyle changes to mitigate the risk of atherosclerosis.

Correct Answer: C

Rationale: A stiff neck is a common sign of meningitis due to inflammation of the meninges. Meningitis typically presents with symptoms such as fever, severe headache, nausea, vomiting, sensitivity to light, and a stiff neck. Joint pain (Choice A) is not a typical symptom of meningitis and is more commonly associated with other conditions. While severe headache (Choice B) can be a symptom of meningitis, it is not as specific as a stiff neck. Coughing up blood (Choice D) is not a typical sign of meningitis and may indicate other respiratory or cardiovascular issues.

Correct Answer: B

Rationale: The correct answer is monitoring the patient's respiratory rate. When a patient receives intravenous morphine, the priority assessment is to monitor the respiratory rate due to the risk of respiratory depression associated with morphine. This assessment helps in detecting and managing any potential respiratory complications promptly. Assessing blood pressure, checking pain level, and monitoring oxygen saturation are important aspects of patient care but are not the priority when considering the specific risk of respiratory depression with intravenous morphine.

Correct Answer: B

Rationale: Monitoring for signs of infection is crucial in clients receiving hemodialysis because they are at an increased risk of infection due to the invasive nature of the procedure. Administering anticoagulants is not typically a part of the routine care for clients undergoing hemodialysis unless specifically prescribed. While a high-protein diet may be beneficial for some clients, it is not a specific intervention related to hemodialysis. Encouraging fluid intake must be individualized based on the client's fluid status and should not be a generalized recommendation for all clients receiving hemodialysis.
