1. Why are blood glucose levels high in type 1 diabetes?
- A. The urinary excretion of glucose is impaired
- B. The lean body mass is metabolized to produce glucose via gluconeogenesis
- C. The absorption of glucose from the gastrointestinal tract is more efficient
- D. There is insufficient insulin to facilitate the transport of glucose into the cells
Correct answer: D: There is insufficient insulin to facilitate the transport of glucose into the cells
Rationale: In type 1 diabetes, the body's immune system destroys the beta cells in the pancreas that produce insulin. This leads to an insufficient amount of insulin, which is required to facilitate the transport of glucose into the cells. Consequently, blood glucose levels remain high. The other options are incorrect. Option A is incorrect because urinary excretion of glucose does not directly contribute to blood glucose levels. Option B is incorrect because, while gluconeogenesis does produce glucose, it is not the cause of high glucose levels in type 1 diabetes. Option C is incorrect because absorption efficiency of glucose from the gastrointestinal tract does not affect the amount of insulin available to transport glucose into cells.
2. The nurse is teaching a client with debilitating rheumatoid arthritis about home safety. Which statement should the nurse include?
- A. “My grandfather always had problems with his arthritis, and he would tell me that it is better to be more stoic and not let pain interrupt your life”
- B. “There are many adaptive devices such as grab bars, reaching tools, grasping devices, and adaptive silverware available that may help you.”
- C. “Place throw rugs throughout your home. You will enjoy how pretty they are, and you can use them to cover up power cords, so you do not trip on them.”
- D. “Lack of home safety may be an issue of compliance. Are you being compliant with your medication?”
Correct answer: “There are many adaptive devices such as grab bars, reaching tools, grasping devices, and adaptive silverware available that may help you.”
Rationale: The correct answer is B. This statement is the most appropriate because it focuses on providing practical solutions to enhance the client's safety at home while managing rheumatoid arthritis. Adaptive devices like grab bars, reaching tools, grasping devices, and adaptive silverware can help the client maintain independence and prevent accidents. Choice A is incorrect as it does not provide practical advice on home safety but rather a personal anecdote. Choice C is incorrect as throw rugs can pose a tripping hazard instead of enhancing safety. Choice D is also incorrect as it does not directly address home safety measures but rather shifts the focus to medication compliance.
3. What is the procedure to remove a sample of tissue from the lung for examination under a microscope?
- A. Lung biopsy
- B. Bronchoscopy
- C. Thoracentesis
- D. Lobectomy
Correct answer: A
Rationale: The correct answer is A, lung biopsy. A lung biopsy involves removing a small sample of lung tissue for examination under a microscope to diagnose lung conditions. Choice B, bronchoscopy, is a procedure where a thin, flexible tube with a light and camera is inserted into the airways to view the lungs. This procedure is more for diagnostic purposes and not specifically for tissue removal. Choice C, thoracentesis, is a procedure to remove fluid from the pleural space around the lungs for diagnostic or therapeutic purposes, not for tissue biopsy. Choice D, lobectomy, is a surgical procedure to remove a lobe of the lung, usually done to treat conditions like lung cancer or severe infections, but it does not involve removing tissue for microscopic examination.
4. A nurse is caring for a client who reports difficulty falling asleep. Which of the following recommendations should the nurse make?
- A. Watch a television program in bed before going to sleep.
- B. Drink a cup of hot cocoa before bedtime.
- C. Maintain a consistent time to wake up each day.
- D. Exercise 1 hour before going to bed.
Correct answer: C
Rationale: The correct answer is C: "Maintain a consistent time to wake up each day." Establishing a regular wake-up time helps regulate the body's internal clock and promotes better sleep patterns. Watching television in bed (Choice A) can actually hinder sleep due to the light emitted by screens affecting melatonin production. Drinking beverages with caffeine like hot cocoa (Choice B) close to bedtime can interfere with falling asleep. Exercising vigorously right before bed (Choice D) can increase alertness and make it harder to fall asleep.
5. A nurse is planning to administer multiple medications to a client with dysphagia. What action should the nurse take?
- A. Crush medications and mix them with honey
- B. Provide medications through a straw
- C. Place the medications in small amounts of pudding
- D. Offer the medications with a full glass of water
Correct answer: C
Rationale: The correct action for the nurse to take when administering medications to a client with dysphagia is to place the medications in small amounts of pudding. Mixing medications with pudding helps clients with dysphagia swallow them more easily. Choice A (crushing medications and mixing with honey) is not recommended as it may alter the medication properties. Choice B (providing medications through a straw) is not suitable for clients with dysphagia as it can pose a choking hazard. Choice D (offering medications with a full glass of water) may be difficult for clients with dysphagia to swallow and increase the risk of aspiration.
