Nursing Elites

1. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the LPN/LVN set the client's intravenous infusion pump?

• A. 13 ml/hour
• B. 63 ml/hour
• C. 80 ml/hour
• D. 125 ml/hour

Correct answer: B

Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.

2. Which nutritional assessment data should be collected to best reflect total muscle mass in an adolescent?

• A. Height in inches or centimeters.
• B. Weight in kilograms or pounds.
• C. Triceps skinfold thickness.
• D. Upper arm circumference.

Correct answer: D

Rationale: The correct answer is 'Upper arm circumference.' Upper arm circumference is a better indicator of total muscle mass in adolescents compared to height, weight, or triceps skinfold thickness. Triceps skinfold thickness primarily reflects subcutaneous fat, while weight and height are not specific to muscle mass. Upper arm circumference directly measures the muscle mass in the upper arm and can provide a more accurate assessment in this context. Therefore, choices A, B, and C are incorrect because they do not directly reflect total muscle mass in adolescents.

3. An elderly male client who suffered a cerebral vascular accident is receiving tube feedings via a gastrostomy tube. The LPN knows that the best position for this client during administration of the feedings is

• A. prone.
• B. Fowler's.
• C. Sims'.
• D. supine.

Correct answer: B

Rationale: Fowler's position is the optimal position for a client receiving tube feedings via a gastrostomy tube because it reduces the risk of aspiration. In Fowler's position, the client is sitting up at a 45- to 60-degree angle, which helps prevent the formula from flowing back into the esophagus and causing aspiration pneumonia. Choice A, prone position (lying face down), would not be suitable for administering tube feedings as it increases the risk of aspiration. Sims' position (lying on the left side with the right knee flexed) and supine position (lying flat on the back) are also not ideal for administering tube feedings as they do not provide the same level of protection against aspiration as Fowler's position does.

4. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the LPN/LVN monitor closely while the client is taking this medication?

• A. Blood glucose level
• B. Prothrombin time (PT) and INR
• C. Serum potassium level
• D. Serum creatinine level

Correct answer: B

Rationale: The LPN/LVN should closely monitor Prothrombin time (PT) and INR (Choice B) levels in a client receiving warfarin. These values are crucial to ensure the medication's effectiveness and prevent complications like bleeding. Monitoring blood glucose level (Choice A) is not directly relevant to warfarin therapy. While serum potassium level (Choice C) and serum creatinine level (Choice D) are important for other conditions or medications, they are not specifically required to be monitored when a client is on warfarin.

5. A client is receiving continuous IV fluid therapy via a peripheral vein in the left forearm. Which of the following findings indicates that the client has developed phlebitis at the IV site?

• A. Erythema along the path of the vein
• B. Pitting edema at the insertion site
• C. Coolness of the client’s left forearm
• D. Pallor of the client’s left forearm

Correct answer: A

Rationale: Erythema (redness) along the path of the vein is a classic sign of phlebitis, indicating inflammation of the vein. This occurs due to irritation or infection at the IV site. Pitting edema (choice B) is not typically associated with phlebitis but suggests fluid overload or poor circulation. Coolness (choice C) and pallor (choice D) of the forearm are not characteristic signs of phlebitis but may indicate impaired circulation or reduced blood flow to the area.
