1. A home health nurse is discussing the dangers of carbon monoxide poisoning with a client. Which of the following information should the nurse include?
- A. Carbon monoxide does not have a distinct odor.
- B. Water heaters should be inspected every 5 years.
- C. The lungs are not damaged from carbon monoxide inhalation.
- D. Carbon monoxide binds with hemoglobin in the body.
Correct answer: D
Rationale: The correct answer is D: 'Carbon monoxide binds with hemoglobin in the body.' Carbon monoxide is an odorless, colorless gas, so it does not have a distinct odor (Choice A). While regular inspection of appliances like water heaters is important for safety, it is not directly related to carbon monoxide poisoning (Choice B). Carbon monoxide primarily affects the cardiovascular system by binding with hemoglobin, reducing the blood's ability to carry oxygen, rather than causing direct lung damage (Choice C). Understanding how carbon monoxide binds with hemoglobin is crucial in recognizing the mechanism of poisoning and its potential consequences.
2. The LPN/LVN mixes 50 mg of Nipride in 250 ml of D5W and plans to administer the solution at a rate of 5 mcg/kg/min to a client weighing 182 pounds. Using a drip factor of 60 gtt/ml, how many drops per minute should the client receive?
- A. 31 gtt/min.
- B. 62 gtt/min.
- C. 93 gtt/min.
- D. 124 gtt/min.
Correct answer: D
Rationale: To calculate the drops per minute for the client, first, convert the weight from pounds to kilograms by dividing 182 by 2.2, which equals 82.72 kg. Then, calculate the dose in mcg/min by multiplying the weight in kg by the rate (82.72 kg * 5 mcg/kg/min = 413.6 mcg/min). Next, convert 50 mg to mcg (50 mg * 1000 = 50,000 mcg). Divide the total mcg (50,000 mcg) by the dose per minute (413.6 mcg/min) to get approximately 121 gtt/min. However, since the drip factor is 60 gtt/ml, the correct answer is 124 gtt/min, ensuring the accurate administration rate of the medication. Therefore, choice 'D' is the correct answer. Choices 'A', 'B', and 'C' are incorrect as they do not accurately reflect the calculated drops per minute based on the given information.
3. When entering the room of an adult male, the nurse finds that the client is very anxious. Before providing care, what action should the nurse take?
- A. Divert the client’s attention
- B. Call for additional help from staff
- C. Document the planned action
- D. Re-assess the client's situation
Correct answer: D
Rationale: Re-assessing the client's situation before providing care is the most appropriate action in this scenario. By re-evaluating the client, the nurse can better understand the cause of the anxiety and tailor the care accordingly. Diverting the client's attention (Choice A) may not address the underlying issue causing anxiety. Calling for additional help (Choice B) is not the initial step required unless there is an urgent need. Documenting the planned action (Choice C) should come after reassessing the client to ensure accuracy and relevance.
4. The healthcare provider prescribes the diuretic metolazone (Zaroxolyn) 7.5 mg PO. Zaroxolyn is available in 5 mg tablets. How much should the LPN/LVN plan to administer?
- A. 1/2 tablet.
- B. 1 tablet.
- C. 1 1/2 tablets.
- D. 2 tablets.
Correct answer: C
Rationale: To administer 7.5 mg of metolazone (Zaroxolyn), the LPN/LVN should plan to give 1 1/2 tablets since each tablet contains 5 mg. Choice A (1/2 tablet) would not provide the full prescribed dose. Choice B (1 tablet) would only deliver 5 mg, which is less than the prescribed dose. Choice D (2 tablets) would exceed the prescribed dose, resulting in 10 mg instead of the required 7.5 mg. Therefore, the correct answer is to administer 1 1/2 tablets to achieve the prescribed 7.5 mg.
5. What intervention should be implemented by the LPN to reduce the risk of aspiration in a client with a nasogastric tube receiving continuous enteral feedings?
- A. Elevate the head of the bed to 30-45 degrees.
- B. Check residual volumes every 4 hours.
- C. Verify tube placement every shift.
- D. Flush the tube with water every 4 hours.
Correct answer: A
Rationale: Elevating the head of the bed to 30-45 degrees is crucial in reducing the risk of aspiration because it helps keep the gastric contents lower than the esophagus, thereby promoting proper digestion and preventing reflux. This position also aids in reducing the likelihood of regurgitation and aspiration of gastric contents. Checking residual volumes every 4 hours is important for monitoring feeding tolerance but does not directly address the risk of aspiration. Verifying tube placement every shift is essential for ensuring the tube is correctly positioned within the gastrointestinal tract but does not directly reduce the risk of aspiration. Flushing the tube with water every 4 hours may help maintain tube patency and prevent clogging, but it does not specifically address the risk of aspiration associated with nasogastric tube feedings.
