1. Which of the following is a fatal genetic neurologic disorder whose onset is in middle age?
- A. Tay-Sachs disease
- B. Duchenne muscular dystrophy
- C. Hemophilia
- D. Huntington’s disease
Correct answer: D
Rationale: Huntington's disease is a fatal genetic neurologic disorder characterized by progressive nerve cell degeneration in the brain. It typically manifests in middle age with symptoms such as involuntary movements, cognitive decline, and psychiatric disturbances. Tay-Sachs disease (Choice A) is a genetic disorder that primarily affects the nervous system in early childhood, not middle age. Duchenne muscular dystrophy (Choice B) is a genetic disorder that primarily affects muscle function and usually presents in early childhood. Hemophilia (Choice C) is a genetic disorder related to blood clotting, and its onset is not typically in middle age.
2. Rh incompatibility occurs when an Rh-negative woman is carrying an Rh-positive fetus.
- A. TRUE
- B. FALSE
- C. Sometimes
- D. Never
Correct answer: B
Rationale: Rh incompatibility occurs when an Rh-negative woman is carrying an Rh-positive fetus, not the other way around. Therefore, the statement that an Rh-positive woman is carrying an Rh-negative fetus is incorrect. Rh incompatibility can lead to hemolytic disease of the newborn, where maternal antibodies attack the fetal red blood cells. Choice A is incorrect because the statement is false. Choice C is incorrect as Rh incompatibility has a clear cause and effect relationship. Choice D is incorrect as Rh incompatibility can occur, but it depends on the Rh status of the mother and fetus.
3. Which of the following statements is a symptom of cystic fibrosis in children?
- A. Cystic fibrosis leads to uncontrollable muscle movements and personality changes.
- B. Cystic fibrosis leads to the excessive production of thick mucus that clogs the pancreas and lungs.
- C. Cystic fibrosis causes red blood cells to clump together, obstructing small blood vessels and decreasing the oxygen supply.
- D. Cystic fibrosis causes the central nervous system to degenerate, resulting in death.
Correct answer: B
Rationale: The correct answer is B. Cystic fibrosis is a genetic disorder that causes the body to produce thick, sticky mucus. This mucus can clog the airways in the lungs and obstruct the pancreas, leading to severe respiratory and digestive problems. Choice A is incorrect because uncontrollable muscle movements and personality changes are not typical symptoms of cystic fibrosis. Choice C is incorrect because cystic fibrosis does not directly cause red blood cells to clump together and obstruct small blood vessels. Choice D is incorrect because cystic fibrosis primarily affects the respiratory and digestive systems, not the central nervous system.
4. Following an amniocentesis, a nurse is caring for a client. The nurse should observe the client for which of the following complications?
- A. Hyperemesis
- B. Proteinuria
- C. Hypoxia
- D. Hemorrhage
Correct answer: D
Rationale: After an amniocentesis, the nurse should monitor the client for potential complications, with hemorrhage being a significant concern due to the invasive nature of the procedure. Hyperemesis (severe vomiting), proteinuria (excessive protein in the urine), and hypoxia (low oxygen levels) are not typically associated with amniocentesis and are less likely to occur compared to hemorrhage, which is a more common complication that requires prompt recognition and intervention.
5. A woman with gestational diabetes has had little or no experience reading and interpreting glucose levels. The client shows the nurse her readings for the past few days. Which reading signals the nurse that the client may require an adjustment of insulin or carbohydrates?
- A. 75 mg/dl before lunch. This is low; better eat now.
- B. 115 mg/dl 1 hour after lunch. This is a little high; maybe eat a little less next time.
- C. 115 mg/dl 2 hours after lunch. This is too high; it is time for insulin.
- D. 50 mg/dl just after waking up from a nap. This is too low; maybe eat a snack before going to sleep.
Correct answer: D
Rationale: 50 mg/dl after waking from a nap is too low. During hours of sleep, glucose levels should not be less than 60 mg/dl. Snacks before sleeping can be helpful. The premeal acceptable range is 60 to 99 mg/dl. The readings 1 hour after a meal should be less than 129 mg/dl. Two hours after eating, the readings should be less than 120 mg/dl.
