AACN CCRN-Adult Exam Dumps - Actual Questions Answers

In hypertensive crisis, neurologic changes are often caused by increased intracranial pressure (ICP) as a result of loss of cerebral autoregulation. Autoregulation normally maintains consistent cerebral blood flow despite changes in systemic blood pressure. In hypertensive crisis, the extremely high blood pressure overwhelms these mechanisms, leading to increased cerebral blood flow, disruption of the blood-brain barrier, and cerebral edema, which subsequently increases ICP and causes neurologic changes.References: = CCRN Exam Handbook, page 48

Nutritional supplements are beneficial for patients with neutropenia secondary to chemotherapy, as they can help provide adequate calories, protein, vitamins, and minerals that are essential for immune function and tissue repair. Chemotherapy can cause side effects such as nausea, vomiting, loss of appetite, taste changes, and mouth sores, which can make it difficult for patients to eat enough food and meet their nutritional needs. Nutritional supplements can be in the form of oral drinks, shakes, bars, or powders, or they can be administered through a feeding tube or intravenously. The nurse should request nutritional supplements that are appropriate for the patient’s condition, preferences, and tolerance, and that are compatible with the neutropenic diet and food safety guidelines. The nurse should also monitor the patient’s weight, hydration, and laboratory values, and report any signs of malnutrition, infection, or intolerance to the provider.

• Nutrition for the Person With Cancer During Treatment: A Guide for Patients and Families: This article states that “Nutritional supplements are products that can be used to add nutrients to your diet or to lower your risk of health problems. They can be in pill, capsule, tablet, or liquid form. They might have vitamins, minerals, amino acids, herbs, or other substances. Some examples of common supplements are calcium, iron, omega-3 fatty acids, vitamin C, and vitamin D. You might need supplements if you cannot get enough nutrients from foods or if you have certain health conditions that might cause a deficiency, such as cancer, diabetes, or chronic diarrhea.”
• Nutrition in Cancer Care (PDQ®)–Patient Version: This article states that “Nutritional support is therapy for people who do not get enough nourishment by eating or drinking. You may need nutritional support if you have trouble swallowing, have lost your appetite, or are losing weight. Nutritional support can be given in different ways: Enteral nutrition is liquid food given through a tube (called a feeding tube) into the stomach or small intestine. Parenteral nutrition is a liquid mixture of nutrients given through a vein (intravenous or IV). Oral nutrition is food or liquid taken by mouth. This includes nutritional supplements, such as drinks, shakes, bars, or powders that have protein, carbohydrates, fat, vitamins, and minerals.”
• Nutrition and Cancer: What You Need to Know: This article states that “Nutritional supplements can help you meet your calorie and protein needs when you are not able to eat enough food. They can also provide extra vitamins and minerals. There are many types of nutritional supplements, such as drinks, shakes, puddings, bars, and powders. Some are designed for people with cancer and have extra calories and protein. Your doctor, nurse, or dietitian can help you choose the best supplement for you. You can buy some supplements at the grocery store or pharmacy, but others may need a prescription.”

Noncardiogenic pulmonary edema is most often associated with damage to the alveolar capillary membrane secondary to aspiration. This condition occurs when there is increased permeability of the alveolar-capillary barrier, leading to fluid leakage into the alveoli. It is a hallmark of Acute Respiratory Distress Syndrome (ARDS), which can be triggered by aspiration, resulting in inflammatory damage to the lungs.References: = CCRN Exam Handbook, page 29
