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: Performing carotid massage is not an appropriate action for a nurse to take when a client has signs of a stroke, as it may worsen the condition or cause complications. Carotid massage is a technique that involves applying pressure to the carotid artery in the neck to stimulate the vagus nerve and slow down the heart rate. It is used to treat some types of arrhythmias, such as supraventricular tachycardia. However, carotid massage may dislodge a blood clot or plaque from the carotid artery and cause an embolic stroke, which is a type of ischemic stroke that occurs when a blood clot travels to the brain and blocks a blood vessel. Carotid massage may also cause bradycardia, hypotension, or syncope, which can reduce the blood flow to the brain and worsen the ischemic damage.

Choice B reason: Calling for help is an appropriate action for a nurse to take when a client has signs of a stroke, as it initiates the emergency response and allows for prompt evaluation and treatment. Stroke is a medical emergency that occurs when the blood supply to a part of the brain is interrupted, causing brain cells to die. The sooner the stroke is recognized and treated, the better the chances of survival and recovery. Therefore, the nurse should call for help as soon as possible and activate the stroke protocol in the facility.

Choice C reason: Providing the client with water to test the gag reflex is not an appropriate action for a nurse to take when a client has signs of a stroke, as it may cause aspiration or choking. A gag reflex is an involuntary contraction of the throat muscles that prevents foreign objects from entering the airway. It is tested by touching the back of the throat with a tongue depressor or a cotton swab. However, this test is not indicated in a client who has signs of a stroke, as it may trigger vomiting or coughing, which can increase intracranial pressure or cause bleeding. Moreover, giving water to a client who has signs of a stroke may be dangerous, as they may have dysphagia (difficulty swallowing) or facial weakness, which can impair their ability to swallow safely and increase the risk of aspiration pneumonia.

Choice D reason: Administering thrombolytics is not an appropriate action for a nurse to take when a client has signs of a stroke, as it may be contraindicated or harmful depending on the type and timing of the stroke. Thrombolytics are medications that dissolve blood clots and restore blood flow. They are used to treat ischemic stroke, which is caused by a blood clot that blocks a blood vessel in the brain. However, thrombolytics are not effective for hemorrhagic stroke, which is caused by bleeding into or around the brain. In fact, thrombolytics may worsen hemorrhagic stroke by increasing bleeding and intracranial pressure. Therefore, thrombolytics should only be given after confirming the type of stroke by imaging tests such as computed tomography (CT) scan or magnetic resonance imaging (MRI). Thrombolytics should also be given within a specific time window after the onset of symptoms, usually within 3 to 4.5 hours, as they may lose their effectiveness or cause complications if given too late. Therefore, administering thrombolytics is not an action that a nurse can take without proper assessment and orders from the health care provider.

Choice A reason: The client's financial resources is not the most important factor for the nurse to consider. Although Meals-on-Wheels is a low-cost or free service that provides nutritious meals to homebound seniors and people with disabilities, it does not require a specific income level or financial status to qualify. The nurse should focus on the client's nutritional and functional needs, rather than their economic situation.

Choice B reason: The client's level of family support is not the most important factor for the nurse to consider. Although having family members who can assist with meal preparation and delivery can be helpful and beneficial for the client, it is not a requirement or a guarantee for receiving Meals-on-Wheels. The nurse should assess the client's individual capabilities and preferences, rather than their family availability or involvement.

Choice C reason: The client's access to transportation is not the most important factor for the nurse to consider. Although having access to transportation can enable the client to obtain food and groceries from other sources, such as stores, markets, or restaurants, it is not a criterion or a barrier for receiving Meals-on-Wheels. The nurse should evaluate the client's dietary and health needs, rather than their mobility or transportation options.

Choice D reason: The client's ability to prepare meals is the most important factor for the nurse to consider. Meals-on-Wheels is designed to serve clients who are unable to cook or shop for themselves due to physical, mental, or social limitations. The nurse should determine if the client has any impairments or challenges that prevent them from preparing their own meals, such as vision loss, arthritis, dementia, or isolation. If the client has difficulty or inability to prepare meals, they may be eligible for Meals-on-Wheels.
