Nursing Elites

1. The healthcare professional prepares a 1,000 ml IV of 5% dextrose and water to be infused over 8 hours. The infusion set delivers 10 drops per milliliter. The healthcare professional should regulate the IV to administer approximately how many drops per minute?

• A. 80
• B. 8
• C. 21
• D. 25

Correct answer: C

Rationale: To calculate the drops per minute for the IV infusion, first determine the total drops to be infused over 8 hours. 1,000 ml to be infused over 8 hours means 125 ml per hour (1000 ml / 8 hours = 125 ml/hr). Since the infusion set delivers 10 drops per ml, 125 ml/hr x 10 drops/ml = 1250 drops/hr. To find drops per minute, divide the drops per hour by 60 (minutes in an hour): 1250 drops/hr / 60 minutes = 20.83 drops/minute, which rounds up to 21 drops per minute (Option C). This rate ensures the correct infusion rate over 8 hours. Choices A, B, and D are incorrect calculations and do not provide the appropriate infusion rate needed to administer the IV over the specified time period.

2. When reviewing EBP about the administration of O2 therapy, what is the recommended maximum flow rate for regulating O2 via nasal cannula?

• A. Regulate O2 via nasal cannula no more than 6L
• B. Regulate O2 via nasal cannula no more than 2L
• C. Regulate O2 via nasal cannula no more than 4L
• D. Regulate O2 via nasal cannula no more than 8L

Correct answer: A

Rationale: The correct answer is to regulate O2 via nasal cannula no more than 6L. This flow rate is generally recommended to ensure adequate oxygen delivery without causing discomfort or potential harm to the patient. Choices B, C, and D are incorrect as they suggest flow rates that are either too low (2L, 4L) or too high (8L). A flow rate of 2L might not provide sufficient oxygen, while 4L could be inadequate for some patients. On the other hand, a flow rate of 8L could be excessive and potentially harmful, leading to complications like oxygen toxicity. Therefore, the optimal recommendation is to regulate O2 via nasal cannula at a maximum of 6L to balance effectiveness and safety.

3. 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.

4. When measuring a client's blood pressure, which approach is the priority for a nurse caring for a client with hypertension?

• A. Obtain the blood pressure under the same conditions each time
• B. Use a different arm for each measurement
• C. Measure the blood pressure while the client is standing
• D. Take multiple readings at different times of the day

Correct answer: A

Rationale: The correct approach when measuring a client's blood pressure, especially for a client with hypertension, is to obtain the blood pressure under the same conditions each time. Consistency in measurement conditions helps ensure accurate and comparable blood pressure readings. Using a different arm for each measurement (Choice B) is not ideal as it can lead to variations in readings. Measuring the blood pressure while the client is standing (Choice C) is not the standard practice and may not provide accurate results. Taking multiple readings at different times of the day (Choice D) may be useful for monitoring blood pressure trends but is not the priority when ensuring accurate individual readings.

5. The nurse is preparing to assist a newly admitted client with personal hygiene measures. The nurse wants to assess the client's gag reflex. Which action should the nurse include?

• A. Offer small sips of water through a straw
• B. Place tongue blade on back half of tongue
• C. Use a penlight to observe back of the oral cavity
• D. Auscultate breath sounds after the client swallows

Correct answer: B

Rationale: The correct action for the nurse to include when assessing the client's gag reflex is to place a tongue blade on the back half of the tongue. This method effectively tests the gag reflex without causing discomfort. Choice A is incorrect because offering small sips of water through a straw does not assess the gag reflex. Choice C is incorrect as using a penlight to observe the back of the oral cavity does not directly assess the gag reflex. Choice D is incorrect since auscultating breath sounds after the client swallows does not evaluate the gag reflex.
