1. A nurse is providing teaching to a group of adult athletes about preventing the effects of dehydration on the body. Which of the following manifestations should the nurse include in the teaching?
- A. Impaired motor control
- B. Drop in body temperature during exercise
- C. Increase in appetite
- D. Decreased resting heart rate
Correct answer: A
Rationale: Dehydration can lead to impaired motor control due to electrolyte imbalances affecting muscle function. Choices B, C, and D are incorrect. Dehydration typically causes an increase in body temperature during exercise, not a drop. Dehydration is more likely to suppress appetite, leading to a decrease rather than an increase in appetite. Also, dehydration often results in an increased heart rate rather than a decreased resting heart rate.
2. What condition has been shown to be associated with esophageal dysphagia?
- A. myasthenia gravis
- B. achalasia
- C. Alzheimer's disease
- D. cerebral palsy
Correct answer: B
Rationale: Achalasia is the correct answer. It is a condition characterized by the esophagus having difficulty moving food toward the stomach, resulting in dysphagia (difficulty swallowing). Myasthenia gravis (Choice A) is a neuromuscular disorder that affects skeletal muscles, not the esophagus. Alzheimer's disease (Choice C) primarily affects cognitive function, not the esophagus. Cerebral palsy (Choice D) is a neurological disorder affecting body movement and muscle coordination, unrelated to esophageal dysphagia.
3. Approximately 70 to 80 percent of acute pancreatitis cases are caused by gallstones or _____.
- A. infection
- B. alcohol abuse
- C. diabetes
- D. obesity
Correct answer: B
Rationale: Alcohol abuse is indeed a major cause of acute pancreatitis, along with gallstones, accounting for the majority of cases. While infections, diabetes, and obesity can also contribute to pancreatitis, they are not as prevalent as alcohol abuse and gallstones in causing acute pancreatitis.
4. Located in the middle of the brain, what organ is responsible for satiety and hunger?
- A. Medulla Oblongata
- B. Pituitary Gland
- C. Hypothalamus
- D. Parathyroid
Correct answer: C
Rationale: The hypothalamus, located in the middle of the brain, plays a crucial role in regulating hunger and satiety. It contains specific regions that control appetite and feeding behavior. The Medulla Oblongata (Choice A) is responsible for regulating vital functions like heartbeat and breathing, not hunger. The Pituitary Gland (Choice B) is an endocrine gland that secretes hormones but is not primarily involved in hunger regulation. The Parathyroid (Choice D) is responsible for regulating calcium levels in the body and not related to hunger or satiety.
5. What is the digestive action of lipase?
- A. It breaks down carbohydrates
- B. It breaks down proteins
- C. It breaks down lipids
- D. It aids in fat digestion
Correct answer: C
Rationale: Lipase is an enzyme that specifically breaks down lipids (fats) during the process of digestion, converting them into fatty acids and glycerol. This is why option C is the correct answer. Although option D is partially correct, it's less specific than option C. Lipase does not break down carbohydrates or proteins, so options A and B are incorrect.
