Nursing Elites

1. A healthcare professional in a provider's office is reviewing the laboratory findings of a client who reports chills and aching joints. Which of the following findings should the healthcare professional identify as an indication that the client has an infection?

• A. WBC 15,000/mm³
• B. Hemoglobin 12 g/dL
• C. Platelet count 300,000/mm³
• D. Sodium 140 mEq/L

Correct answer: A

Rationale: An elevated white blood cell count (WBC 15,000/mm³) is a common indicator of infection as the body increases WBC production to fight off pathogens. In conditions like infections, inflammation, or stress, the WBC count can rise. The other options, hemoglobin, platelet count, and sodium levels, are not typically specific indicators of infection. Hemoglobin measures the oxygen-carrying capacity of red blood cells, platelet count assesses clotting ability, and sodium levels indicate electrolyte balance.

2. What is the rate of delivery in mL/hr if a total volume of 750 mL is infused over a period of 7 hours?

• A. 107 mL/hr.
• B. 107 mL/hr.
• C. 107 mL/hr.
• D. 107 mL/hr.

Correct answer: A

Rationale: The correct rate of delivery is 107 mL/hr. To find the rate of delivery, divide the total volume by the total time: 750 mL / 7 hours = 107 mL/hr. Choice B, C, and D are incorrect as they do not match the correct calculation based on the total volume and time provided.

3. A client with lower extremity weakness is being taught a four-point crutch gait by a nurse. Which of the following instructions should the nurse include in the teaching?

• A. Bear weight on both legs.
• B. Move the crutches and the weak leg in unison.
• C. Advance the crutches and the strong leg simultaneously.
• D. Move the crutches forward, then move one leg at a time.

Correct answer: D

Rationale: The correct technique for a four-point crutch gait involves moving the crutches forward, then moving one leg at a time. This method provides stability and support by alternating movement between the crutches and legs. Choice A is incorrect because bearing weight on both legs simultaneously is not the correct method for a four-point gait. Choice B is incorrect as moving the crutches and weak leg together does not provide the required stability. Choice C is incorrect as advancing the crutches and strong leg together does not promote the alternating movement needed for a four-point gait.

4. The client is receiving total parenteral nutrition (TPN). Which laboratory value should the LPN/LVN monitor closely to assess for complications?

• A. Serum potassium
• B. Blood glucose
• C. Serum sodium
• D. Serum calcium

Correct answer: B

Rationale: The correct answer is B: Blood glucose. When caring for a client receiving total parenteral nutrition (TPN), monitoring blood glucose levels is essential due to the risk of hyperglycemia. TPN solutions are high in glucose, and clients may be at risk of developing hyperglycemia if the infusion rate is too high or if there are underlying issues such as insulin resistance. Monitoring serum potassium (choice A) is important but not the most crucial value to monitor in clients receiving TPN. Serum sodium (choice C) and serum calcium (choice D) are not directly impacted by TPN administration and are less likely to be affected compared to blood glucose levels.

5. 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.
