Question 1 of 5
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?
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.
Question 2 of 5
A client admitted with sudden onset of severe back pain of unknown origin. Which statement would be most effective for the nurse to use to elicit further information from this client about his pain?
Correct Answer: B
Rationale: The correct answer is B: 'Describe the pain you are experiencing.' This question is the most effective as it prompts the client to provide detailed information about the nature of the pain, including its characteristics, intensity, and location. This detailed description can help the nurse in assessing the possible cause and severity of the pain. Choices A, C, and D are not as effective as they are either too general ('Tell me how you are feeling right now'), redundant ('Can you tell me more about your back pain?'), or focused only on timing and severity ('When did the pain start and how severe is it?').
Question 3 of 5
A client with heart failure is being taught by a nurse on reducing daily sodium intake. Which factor is most crucial in determining the client's ability to learn new dietary habits?
Correct Answer: D
Rationale: The client's previous dietary knowledge is the most critical factor in determining the ability to learn new dietary habits. Understanding the client's existing dietary knowledge helps tailor the teaching to build upon what they already know. While client involvement in planning changes can increase adherence and motivation, the foundational knowledge is essential for effective learning. The cost of dietary changes and the availability of low-sodium foods are important considerations but not as crucial as the client's existing knowledge.
Question 4 of 5
The healthcare provider is assessing a client with acute pancreatitis. Which finding is most concerning?
Correct Answer: B
Rationale: In acute pancreatitis, a low blood pressure of 95/60 mmHg is the most concerning finding as it may indicate hypovolemia or shock, which are critical conditions requiring immediate intervention. Pain radiating to the back is a common symptom of pancreatitis but is not as immediately life-threatening as hypotension. Elevated serum amylase levels and absent bowel sounds are typical findings in acute pancreatitis and may indicate pancreatic inflammation and gastrointestinal motility issues, respectively, but they are not as acutely concerning as hypotension.
Question 5 of 5
What is the most important action for the LPN/LVN to take to prevent infection in a client with an indwelling urinary catheter?
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.
