1. A nurse at an assisted living facility is preparing an in-service for residents about electrical safety. Which of the following instructions should the nurse include?
- A. Avoid taping electrical cords to the floor.
- B. Clean electrical equipment before disconnection.
- C. Cover exposed wires with tape before use.
- D. Disconnect electrical equipment by grasping the plug.
Correct answer: A
Rationale: The correct instruction for electrical safety is to avoid taping electrical cords to the floor. Taping cords can create tripping hazards, leading to falls and potential injuries. Choice B, cleaning electrical equipment before disconnection, is not directly related to electrical safety but rather to equipment maintenance. Choice C, covering exposed wires with tape before use, is incorrect as exposed wires should be properly insulated and repaired by a qualified professional. Choice D, disconnecting electrical equipment by grasping the plug, is unsafe and can lead to electrical shocks. It is always recommended to unplug devices by holding the plug itself, not by pulling the cord.
2. The healthcare professional is preparing to administer a tuberculin skin test. Which site is most appropriate for this injection?
- A. Deltoid muscle
- B. Vastus lateralis muscle
- C. Abdomen
- D. Inner forearm
Correct answer: D
Rationale: The inner forearm is the most appropriate site for administering a tuberculin skin test. This test requires an intradermal injection, which is administered just below the surface of the skin. The inner forearm provides a flat, easily accessible surface for this type of injection. Choices A, B, and C are incorrect because the tuberculin skin test should not be administered into a muscle (deltoid muscle or vastus lateralis muscle) or into the abdomen. The test requires precise placement within the dermal layer of the skin on the inner forearm to accurately assess for a reaction.
3. The healthcare provider is assessing a client with acute pancreatitis. Which finding is most concerning?
- A. Pain radiating to the back
- B. Blood pressure of 95/60 mmHg
- C. Elevated serum amylase
- D. Absent bowel sounds
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.
4. The healthcare provider prescribes morphine sulfate 4mg IM STAT. Morphine comes in 8 mg per ml. How many ml should the LPN/LVN administer?
- A. 0.5 ml
- B. 1 ml
- C. 1.5 ml
- D. 2 ml
Correct answer: A
Rationale: To administer 4 mg of morphine, as prescribed, the LPN/LVN needs to calculate the correct volume based on the concentration provided (8 mg per ml). Since the desired dose is 4 mg, half of 8 mg (0.5 ml) is required to administer the correct amount. Therefore, the correct answer is 0.5 ml. Choices B, C, and D are incorrect as they would either underdose or overdose the patient.
5. A nurse in a provider's office is assessing the deep tendon reflexes of a client. Which of the following techniques should the nurse identify as indicating the correct method for eliciting the client's patellar reflex?
- A. Tap just below the knee
- B. Tap on the upper thigh
- C. Tap on the ankle
- D. Tap on the lower leg
Correct answer: A
Rationale: The correct technique for eliciting the client's patellar reflex is to tap just below the knee. This action stimulates the stretch receptors in the patellar tendon, leading to a reflex contraction of the quadriceps muscle and extension of the lower leg. Tapping on the upper thigh (Choice B) would not elicit the patellar reflex as it targets a different area. Similarly, tapping on the ankle (Choice C) or tapping on the lower leg (Choice D) would not produce the desired response associated with the patellar reflex, making them incorrect choices.
