1. The client is advised to take dexamethasone (Decadron) with food or milk. What is the physiological basis for this advice?

• A. Inhibits pepsin production
• B. Stimulates hydrochloric acid production
• C. Delays stomach emptying time
• D. Reduces hydrochloric acid production

Correct answer: B

Rationale: The correct answer is B: Stimulates hydrochloric acid production. Dexamethasone can stimulate the production of hydrochloric acid in the stomach, which may lead to irritation of the stomach lining. Taking dexamethasone with food or milk helps to neutralize or buffer the acid, reducing the risk of stomach irritation. Choice A is incorrect because dexamethasone does not inhibit pepsin production. Choice C is incorrect as dexamethasone does not slow stomach emptying time. Choice D is incorrect as dexamethasone does not reduce hydrochloric acid production.

2. 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.

3. What is the most important action for the LPN/LVN to take to prevent infection in a client with an indwelling urinary catheter?

• A. Ensure the catheter tubing is free of kinks.
• B. Change the catheter every 72 hours.
• C. Clean the perineal area with an antiseptic solution daily.
• D. Irrigate the catheter with normal saline every shift.

Correct answer: A

Rationale: The most crucial action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. This step helps prevent obstruction in the tubing, maintaining proper urine flow and reducing the risk of infection. Changing the catheter every 72 hours is not recommended unless clinically indicated, as routine changes can increase the risk of introducing pathogens. Cleaning the perineal area with an antiseptic solution is essential for general hygiene but does not directly prevent catheter-related infections. Irrigating the catheter with normal saline every shift is not a standard practice and can introduce microorganisms into the urinary tract, increasing the risk of infection.

4. A client has a new prescription for parenteral nutrition (PN) in 20% dextrose and fat emulsions. Which of the following is an appropriate action to include in the plan of care?

• A. Monitor blood glucose levels daily.
• B. Change the PN infusion bag every 24 hours.
• C. Prepare the client for a central venous line.
• D. Administer the PN and fat emulsion together.

Correct answer: C

Rationale: When a client requires parenteral nutrition (PN) with a high dextrose concentration, such as 20%, it typically has a high osmolarity. High osmolarity solutions should be infused through a central venous line to prevent peripheral vein irritation and potential complications. Therefore, preparing the client for a central venous line is essential for the safe administration of PN with high dextrose. Monitoring blood glucose levels daily is important but not directly related to the need for a central venous line. Changing the PN infusion bag every 24 hours helps prevent bacterial contamination, but it is not the most critical action in this scenario. Administering the PN and fat emulsion together or separately is a matter of compatibility and administration guidelines, but it is not the key concern in this situation.

5. The LPN/LVN mixes 50 mg of Nipride in 250 ml of D5W and plans to administer the solution at a rate of 5 mcg/kg/min to a client weighing 182 pounds. Using a drip factor of 60 gtt/ml, how many drops per minute should the client receive?

• A. 31 gtt/min.
• B. 62 gtt/min.
• C. 93 gtt/min.
• D. 124 gtt/min.

Correct answer: D

Rationale: To calculate the drops per minute for the client, first, convert the weight from pounds to kilograms by dividing 182 by 2.2, which equals 82.72 kg. Then, calculate the dose in mcg/min by multiplying the weight in kg by the rate (82.72 kg * 5 mcg/kg/min = 413.6 mcg/min). Next, convert 50 mg to mcg (50 mg * 1000 = 50,000 mcg). Divide the total mcg (50,000 mcg) by the dose per minute (413.6 mcg/min) to get approximately 121 gtt/min. However, since the drip factor is 60 gtt/ml, the correct answer is 124 gtt/min, ensuring the accurate administration rate of the medication. Therefore, choice 'D' is the correct answer. Choices 'A', 'B', and 'C' are incorrect as they do not accurately reflect the calculated drops per minute based on the given information.
