| 1. | When explaining the role of liver Kupffer cells to a group of nursing students, which of the following statements about the function of these cells is most accurate? | |
| A) | The primary function of Kupffer cells is to secrete bile. | |
| B) | These cells are the functional unit of the liver and are responsible for all liver secretions. | |
| C) | The cells are capable of removing and phagocytizing old and defective blood cells. | |
| D) | The role of the Kupffer cells is to provide at least 50% of cardiac output each minute to each lobular of the liver. | |
| Ans: | C | |
| Feedback: | ||
| Kupffer cells are reticuloendothelial cells that are capable of removing and phagocytizing old and defective blood cells, bacteria, and other foreign material from the portal blood as it flows through the sinusoid. This phagocytic action removes enteric bacilli and other harmful substances that filter into the blood from the intestine. Small tubular channels in the liver secrete bile. The functional unit of the liver is lobule. Approximately 25% of blood per minute enters the liver through the hepatic artery. | ||
| 2. | A 51-year-old male has been diagnosed with alcohol-induced liver disease. He admits to the nurse providing his care that, “I know what the lungs do, and I know what the heart does, but honestly I have no idea what the liver does in the body.” Which of the following statements would best underlie the explanation that the nurse provides? | |
| A) | The liver is responsible for the absorption of most dietary nutrients as well as the production of growth hormones. | |
| B) | The liver contributes to the metabolism of ingested food and provides the fluids that the GI tract requires. | |
| C) | The liver metabolizes most components of food and also cleans the blood of bacteria and drugs. | |
| D) | The liver maintains a balanced level of electrolytes and pH in the body and stores glucose, minerals, and vitamins. | |
| Ans: | C | |
| Feedback: | ||
| The liver metabolizes protein, carbohydrate, and fat. As well, it metabolizes drugs and removes bacteria by Kupffer cells. Absorption of nutrients takes place in the intestines, and the liver does not produce the bulk of fluids secreted in the GI tract. The liver does not have a primary role in the maintenance of acid–base or electrolyte balance. | ||
| 3. | A patient being seen in the clinic has just received his routine lab results. The patient has been told that his cholesterol level is extremely elevated. The physician plans to give the patient a prescription for medication to help control this condition. Which of the following medications should the nurse prepare to educate the patient on? | |
| A) | Atorvastatin (Lipitor) | |
| B) | Abilify (aripiprazole) | |
| C) | Pancrecarb (Pancrelipase) | |
| D) | Pancrelipase (Ultrase) | |
| Ans: | A | |
| Feedback: | ||
| The HMG-CoA reductase inhibitors or statins are used to treat high cholesterol levels by inhibiting this step in cholesterol synthesis. Abilify is for schizophrenia; Pancrecarb and Pancrelipase are pancreatic enzymes used for pancreatitis. | ||
| 4. | A 48-year-old woman has been diagnosed with extrahepatic cholestasis following a thorough history, ultrasound, and blood work. Which of the following symptoms most likely caused her to seek medical treatment, and what consequence to her health problem would the medical team anticipate? | |
| A) | Complaints of lower flank pain with consequences of impaired fat metabolism | |
| B) | Anorexia with consequences of impaired drug metabolism and blood filtration | |
| C) | Skin xanthomas (focal accumulations of cholesterol) with consequences of increased risk of bleeding due to deficient clotting factors | |
| D) | Pruritus with consequences of deficient levels of fat-soluble vitamins | |
| Ans: | D | |
| Feedback: | ||
| Pruritus is the most common symptom of cholestasis, and deficiencies in fat-soluble vitamins such as A, D, and K are frequent. Flank pain is not a noted complaint, and bile does not contribute to drug metabolism, blood filtration, or clotting factor production. | ||
