A nursing preceptor is reviewing life expectancy in the twentieth century with a new nurse. The nurse should recognize that which of the following was most responsible for the dramatic increase in life expectancy during the twentieth century.

Choice A reason: Analgesics are medications that relieve pain by blocking pain signals or reducing inflammation. They include nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, and acetaminophen. However, analgesics are not very effective in treating trigeminal neuralgia, as they do not address the underlying cause of the pain, which is the compression or irritation of the trigeminal nerve.

Choice B reason: Antihistamines are medications that block the effects of histamine, a chemical that causes allergic reactions such as itching, sneezing, and swelling. They include diphenhydramine, cetirizine, and loratadine. Antihistamines are not effective in treating trigeminal neuralgia, as they do not affect the trigeminal nerve or its function.

Choice C reason: Antibiotics are medications that kill or inhibit the growth of bacteria that cause infections. They include penicillin, amoxicillin, and ciprofloxacin. Antibiotics are not effective in treating trigeminal neuralgia, as they do not target the trigeminal nerve or its pathology.

Choice D reason: Anticonvulsants are medications that prevent or reduce the frequency and severity of seizures by stabilizing the electrical activity of the brain. They include carbamazepine, gabapentin, and phenytoin. Anticonvulsants are the most effective medications in treating trigeminal neuralgia, as they reduce the abnormal firing of the trigeminal nerve that causes the pain. Anticonvulsants are considered the first-line therapy for trigeminal neuralgia and can provide significant relief for most clients.

Choice A reason: Delivering a urine specimen to the laboratory is not a priority task, as it does not affect the client's immediate health or safety. This task can be done later or delegated to another staff member.

Choice B reason: Feeding a client who has bilateral casts is an important task, as it helps the client meet their nutritional needs and prevents complications such as pressure ulcers. However, this task is not as urgent as monitoring blood glucose levels, as it can be done within a reasonable time frame without causing harm to the client.

Choice C reason: Performing blood glucose monitoring of a client who has a prescription for short-acting insulin is a priority task, as it determines the dosage of insulin that the client needs to receive. Insulin is a high-alert medication that can cause serious adverse effects if given incorrectly. Therefore, this task should be done first by the AP who has been trained and certified to do so.

Choice D reason: Obtaining an extra box of tissues for a client who is concerned about running out of them is a low-priority task, as it does not affect the client's physical or psychological well-being. This task can be done at any time or delegated to another staff member.
