1. A healthcare professional is preparing to administer 0.9% sodium chloride (0.9% NaCl) 250 mL IV to infuse over 30 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the healthcare professional adjust the manual IV infusion to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)
- A. 83 gtt/min
- B. 125 gtt/min
- C. 100 gtt/min
- D. 75 gtt/min
Correct answer: C
Rationale: To administer 250 mL over 30 min with a drop factor of 10 gtt/mL, the healthcare professional should adjust the IV infusion to deliver 100 gtt/min. The correct calculation is: (250 mL รท 30 min) x 10 gtt/mL = 100 gtt/min. This rate ensures the proper administration of the IV solution within the specified time frame. Choices A, B, and D are incorrect as they do not align with the accurate calculation based on the provided data.
2. During the initial physical assessment of a newly admitted client with a pressure ulcer, an LPN observes that the client's skin is dry and scaly. The nurse applies emollients and reinforces the dressing on the pressure ulcer. Legally, were the nurse's actions adequate?
- A. The nurse should have also initiated a plan to increase activity.
- B. The nurse provided supportive nursing care for the well-being of the client.
- C. Debridement of the pressure ulcer should have been performed before applying the dressing.
- D. Treatment should not have been initiated until the healthcare provider's prescriptions were received.
Correct answer: B
Rationale: The correct answer is B. Providing supportive nursing care, such as applying emollients and reinforcing the dressing on the pressure ulcer, meets the immediate needs of the client and is in line with legal and professional standards. Option A is incorrect because increasing activity may not be directly related to the immediate skin care needs of the client. Option C is incorrect as debridement might not be immediately necessary based on the initial assessment. Option D is incorrect as nurses are often authorized to initiate treatments within their scope of practice without waiting for healthcare provider prescriptions, especially for routine care like skin moisturization and dressing reinforcement.
3. A client is receiving discharge teaching about a new prescription for digoxin (Lanoxin). Which statement by the client indicates a need for further teaching?
- A. I should avoid foods high in potassium while taking this medication.
- B. I will check my pulse before taking the medication.
- C. I should avoid taking antacids simultaneously with this medication.
- D. I will take the medication at the same time every day.
Correct answer: A
Rationale: The correct answer is A because clients taking digoxin should avoid foods high in potassium. High potassium levels can potentiate the effects of digoxin, leading to toxicity. Choices B, C, and D are correct statements regarding digoxin administration. Checking the pulse before taking the medication helps monitor for signs of digoxin toxicity. Avoiding taking antacids simultaneously prevents interactions that may reduce digoxin absorption. Taking the medication at the same time every day helps maintain a consistent blood level, ensuring optimal therapeutic effects.
4. A client with acute hemorrhagic anemia is to receive four units of packed RBCs (red blood cells) as rapidly as possible. Which intervention is most important for the LPN/LVN to implement?
- A. Obtain the pre-transfusion hemoglobin level.
- B. Prime the tubing and set up the blood pump.
- C. Monitor vital signs every 15 minutes for the first hour.
- D. Ensure the accuracy of the blood type match.
Correct answer: D
Rationale: Ensuring the accuracy of the blood type match is crucial to prevent transfusion reactions. The LPN/LVN must prioritize this step to avoid adverse outcomes. Obtaining the pre-transfusion hemoglobin level (Option A) is important but not as critical as ensuring blood type compatibility. Priming the tubing and setting up the blood pump (Option B) and monitoring vital signs every 15 minutes (Option C) are essential steps in the transfusion process, but the primary concern should be preventing transfusion reactions by verifying blood type compatibility.
5. A child is injured on the school playground and appears to have a fractured leg. What action should the school nurse take first?
- A. Call for emergency transport to the hospital
- B. Immobilize the limb and joints above and below the injury
- C. Assess the child and the extent of the injury
- D. Apply cold compresses to the injured area
Correct answer: C
Rationale: The correct first action for the school nurse to take when a child is injured and appears to have a fractured leg is to assess the child and the extent of the injury. This initial assessment is crucial to determine the severity of the injury before proceeding with further interventions. Option A, calling for emergency transport, should only be done after assessing the extent of the injury. Option B, immobilizing the limb and joints, is important but should come after the initial assessment. Option D, applying cold compresses, is not recommended for suspected fractures as it can exacerbate swelling and pain.
