1. The healthcare provider prescribes furosemide (Lasix) 15 mg IV stat. On hand is Lasix 20 mg/2 ml. How many milliliters should the LPN/LVN administer?
- A. 1 ml.
- B. 1.5 ml.
- C. 1.75 ml.
- D. 2 ml.
Correct answer: B
Rationale: To calculate the correct dose of 15 mg, the LPN/LVN should administer 1.5 ml of Lasix (20 mg/2 ml). This calculation ensures precise dosing. Choice A (1 ml) is too low and would provide only 10 mg, while choice C (1.75 ml) and choice D (2 ml) would exceed the prescribed dose, resulting in potential adverse effects. It is important for the LPN/LVN to administer the exact prescribed dose to ensure therapeutic efficacy and avoid unnecessary complications.
2. A client with a history of heart failure presents with increased shortness of breath and swelling in the legs. What is the most important assessment for the LPN/LVN to perform?
- A. Monitor the client's oxygen saturation level.
- B. Assess the client's apical pulse.
- C. Check for jugular vein distention.
- D. Measure the client's urine output.
Correct answer: C
Rationale: Checking for jugular vein distention is crucial in assessing fluid overload in clients with heart failure. Jugular vein distention indicates increased central venous pressure, which can be a sign of worsening heart failure. Monitoring oxygen saturation (Choice A) is important but may not provide immediate information on fluid status. Assessing the apical pulse (Choice B) is relevant for monitoring heart rate but may not directly indicate fluid overload. Measuring urine output (Choice D) is essential for assessing renal function and fluid balance but does not provide immediate information on fluid overload in this scenario.
3. What is the most important action for preventing infection in a client with a central venous catheter?
- A. Changing the catheter dressing every 72 hours.
- B. Flushing the catheter with heparin solution daily.
- C. Ensuring the catheter is clamped when not in use.
- D. Maintaining sterile technique when handling the catheter.
Correct answer: D
Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. This action helps minimize the introduction of pathogens into the catheter site, reducing the risk of contamination and subsequent infection. Changing the catheter dressing every 72 hours, while important, does not directly address the prevention of infection at the insertion site. Flushing the catheter with heparin solution daily helps prevent occlusion but does not primarily focus on infection prevention. Ensuring the catheter is clamped when not in use is essential for preventing air embolism but does not directly relate to infection control.
4. A healthcare professional is caring for a client who has pharyngeal diphtheria. Which of the following types of transmission precautions should the healthcare professional initiate?
- A. Contact
- B. Droplet
- C. Airborne
- D. Protective
Correct answer: B
Rationale: The correct answer is B: Droplet. Droplet precautions are required for infections that spread via droplets larger than 5 microns in diameter, such as pharyngeal diphtheria. Contact precautions are used for diseases that spread by direct or indirect contact. Airborne precautions are for diseases that spread through small particles in the air. Protective precautions are not a standard precautionary measure for specific infections like pharyngeal diphtheria.
5. During an admission assessment, a healthcare professional finds a client's radial pulse rate to be 68/min and the simultaneous apical pulse to be 84/min. What is the client’s pulse deficit (per minute)?
- A. 16
- B. 12
- C. 6
- D. 14
Correct answer: A
Rationale: The pulse deficit is calculated by finding the difference between the apical and radial pulse rates. In this case, the difference is 84 - 68 = 16. This indicates that there is a pulse deficit of 16 beats per minute. Choices B, C, and D are incorrect as they do not accurately reflect the difference between the two pulse rates.
