Nursing Elites

1. A community health nurse is preparing a campaign about seasonal influenza. Which of the following plans should the nurse include as a secondary prevention?

• A. Screening groups of older adults in nursing care facilities for early influenza manifestations
• B. Promoting hand hygiene to prevent the spread of influenza
• C. Administering influenza vaccinations
• D. Educating about the importance of healthy lifestyle choices to prevent influenza

Correct answer: A

Rationale: The correct answer is A. Secondary prevention aims to detect and address health issues early. Screening older adults in nursing care facilities for early influenza manifestations is an example of secondary prevention by identifying cases at an early stage. Choice B, promoting hand hygiene, is a form of primary prevention that aims to prevent the occurrence of influenza. Choice C, administering influenza vaccinations, is a form of primary prevention as well, focusing on preventing the disease before it occurs. Choice D, educating about healthy lifestyle choices, is more related to health promotion and primary prevention rather than secondary prevention.

2. A client with a history of severe anxiety is scheduled for surgery. Which preoperative medication is the most appropriate for the LPN/LVN to administer to this client?

• A. Lorazepam (Ativan)
• B. Morphine sulfate
• C. Meperidine (Demerol)
• D. Promethazine (Phenergan)

Correct answer: A

Rationale: Lorazepam (Ativan) is the most appropriate preoperative medication for a client with severe anxiety. Lorazepam belongs to the benzodiazepine class and is commonly used to manage anxiety before surgical procedures due to its anxiolytic properties. Morphine sulfate and Meperidine (Demerol) are opioid analgesics, not typically indicated for preoperative anxiety. Promethazine (Phenergan) is an antihistamine used for nausea and vomiting, not anxiety management.

3. The healthcare provider prescribes 1,000 ml of Ringer's Lactate with 30 Units of Pitocin to run over 4 hours for a client who has just delivered a 10-pound infant by cesarean section. The tubing has been changed to a 20 gtt/ml administration set. The LPN/LVN plans to set the flow rate at how many gtt/min?

• A. 42 gtt/min
• B. 83 gtt/min
• C. 125 gtt/min
• D. 250 gtt/min

Correct answer: B

Rationale: To calculate the flow rate in drops per minute (gtt/min), the formula is Total volume (mL) ÷ Time (min) ÷ Drop factor (gtt/mL). In this case, 1000 mL ÷ 240 min ÷ 20 gtt/mL = 83 gtt/min. Therefore, setting the flow rate to 83 gtt/min ensures the correct administration of the IV fluids and medication. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the provided information.

4. Postoperative client with fluid volume deficit. Which change indicates successful treatment?

• A. Decrease in heart rate
• B. Increase in blood pressure
• C. Decrease in respiratory rate
• D. Increase in urine output

Correct answer: A

Rationale: A decrease in heart rate can indicate improved fluid balance and successful treatment of fluid volume deficit. When a client is experiencing fluid volume deficit, the heart rate typically increases as a compensatory mechanism to maintain cardiac output. As fluid volume is restored and the deficit is corrected, the heart rate should decrease back towards a normal range. Choices B, C, and D are less likely to be directly related to the successful treatment of fluid volume deficit. An increase in blood pressure may occur as a compensatory response to fluid volume deficit; a decrease in respiratory rate is not a typical indicator of fluid volume deficit correction; and an increase in urine output can be a sign of improved kidney function but may not directly reflect fluid volume status.

5. 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.
