Nursing Elites

1. A healthcare professional is preparing to administer 750 mL of 0.9% sodium chloride IV to infuse over 7 hours. The healthcare professional should set the pump to deliver how many mL/hr?

• A. 107 mL/hr
• B. 75 mL/hr
• C. 90 mL/hr
• D. 60 mL/hr

Correct answer: A

Rationale: To calculate the mL/hr rate for the infusion, divide the total volume (750 mL) by the total time (7 hours). 750 mL ÷ 7 hours = 107 mL/hr. This means that the pump should be set to deliver approximately 107 mL/hr. Choice B (75 mL/hr) is incorrect because it does not reflect the correct calculation. Choice C (90 mL/hr) is incorrect as it does not align with the accurate calculation. Choice D (60 mL/hr) is incorrect as it does not match the correct mL/hr rate obtained through the calculation.

2. A client with a left leg cast is being taught how to use crutches. Which of the following statements should indicate to the nurse that the client understands the teaching?

• A. When descending stairs, I will first shift my weight to my right (unaffected) leg.
• B. I will use crutches to support my weight on my left leg.
• C. When ascending stairs, I will lead with my left leg.
• D. I will keep my crutches under my arms for support.

Correct answer: A

Rationale: The correct answer is A. Shifting weight to the unaffected leg when descending stairs is crucial for maintaining balance and safety. This technique helps prevent falls and distributes weight appropriately. Choices B, C, and D are incorrect because using crutches to support the weight on the injured leg, leading with the injured leg when ascending stairs, and keeping crutches under the arms are all potentially unsafe practices that could lead to further injury or accidents.

3. A healthcare professional is administering 1 L of 0.9% sodium chloride to a client who is postoperative and has fluid volume deficit. Which of the following changes should the healthcare professional identify as an indication that the treatment was successful?

• A. Decrease in heart rate
• B. Fluid volume deficit causes tachycardia
• C. Decrease in blood pressure
• D. Increase in respiratory rate

Correct answer: A

Rationale: A decrease in heart rate can indicate that the fluid volume deficit is improving. In cases of fluid volume deficit, the body compensates by increasing the heart rate to maintain adequate perfusion. Therefore, a decrease in heart rate after fluid resuscitation suggests that the body's perfusion status is improving. Choices B, C, and D are incorrect because fluid volume deficit typically causes tachycardia, not a decrease in heart rate, and would not result in a decrease in blood pressure or an increase in respiratory rate as primary signs of improvement.

4. A client with diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. What is the most important action for the LPN/LVN to take?

• A. Encourage the client to increase fluid intake.
• B. Monitor the client's blood glucose level.
• C. Administer insulin as prescribed.
• D. Assess the client's urine output.

Correct answer: B

Rationale: The correct answer is to monitor the client's blood glucose level. When a client with diabetes mellitus presents with symptoms of polyuria, polydipsia, and polyphagia, it indicates hyperglycemia. Monitoring blood glucose levels is crucial to assess and manage the client's condition effectively. Option A, encouraging the client to increase fluid intake, may exacerbate polyuria. Option C, administering insulin, should be done based on the healthcare provider's prescription after assessing the blood glucose level. Option D, assessing the client's urine output, is important but not the most immediate action needed in this scenario; monitoring blood glucose levels takes precedence.

5. The healthcare professional is preparing to administer an intramuscular injection to an adult client. Which site is most appropriate for the LPN/LVN to use?

• A. Deltoid muscle
• B. Ventrogluteal site
• C. Dorsogluteal site
• D. Rectus femoris site

Correct answer: B

Rationale: The ventrogluteal site is the most appropriate and safest site for administering an intramuscular injection to an adult client. It is preferred due to its thick muscle mass and fewer major blood vessels and nerves in the area, reducing the risk of injury or complications. The deltoid muscle is commonly used for vaccines and small-volume injections but may not be suitable for larger volumes. The dorsogluteal site has fallen out of favor due to the risk of injury to the sciatic nerve and other underlying structures. The rectus femoris site is not typically used for intramuscular injections in adults.
