1. A client has a new prescription for a home oxygen concentrator. Which of the following instructions should the nurse provide to the client and their family?
- A. Check the cord routinely for frays or tearing
- B. Use oxygen around open flames
- C. Store oxygen concentrator in a closet
- D. Wear synthetic clothing to prevent static electricity
Correct answer: A
Rationale: The correct answer is to instruct the client and their family to check the cord routinely for frays or tearing. This is crucial to ensure the safety and proper function of the oxygen concentrator. Choice B is incorrect because oxygen should never be used around open flames due to the risk of fire. Choice C is also incorrect as oxygen cylinders or concentrators should not be stored in a closet due to ventilation and safety concerns. Choice D is incorrect because synthetic clothing can generate static electricity, which could pose a risk around oxygen equipment.
2. A client with a history of chronic renal failure is admitted with generalized edema. Which laboratory value should the LPN/LVN monitor to assess the client's fluid balance?
- A. Serum potassium
- B. Serum calcium
- C. Serum albumin
- D. Serum sodium
Correct answer: C
Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.
3. A client with a new colostomy is being taught how to irrigate the ostomy. The healthcare provider realizes that the client needs further teaching when the client:
- A. Positions the irrigating solution bag 30 inches below the stoma
- B. Uses an open system for irrigation
- C. Irrigates the colostomy twice a day
- D. Cleans the stoma with harsh chemicals
Correct answer: A
Rationale: The correct answer is A. Positioning the irrigating solution bag 30 inches below the stoma would cause discomfort and ineffective irrigation as the bag should be positioned at a lower level. Option B is incorrect because a closed system for irrigation is the preferred method for colostomy irrigation. Option C is incorrect as colostomy irrigation is typically done once a day unless otherwise instructed by a healthcare provider. Option D is incorrect as the stoma should be cleaned with mild soap and water to prevent skin irritation and damage.
4. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?
- A. 11,000 units.
- B. 13,000 units.
- C. 15,000 units.
- D. 17,000 units.
Correct answer: A
Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.
5. A nurse educator is presenting a module on basic first aid for newly licensed home health nurses. The client who has heat stroke will have which of the following?
- A. Hypotension
- B. Bradycardia
- C. Clammy skin
- D. Bradypnea
Correct answer: A
Rationale: The correct answer is A: Hypotension. Heat stroke is characterized by elevated body temperature, which can lead to hypotension (low blood pressure) due to dehydration and vasodilation. Bradycardia (slow heart rate) and clammy skin are not typical findings in heat stroke. Bradypnea (slow breathing) is also not a common feature of heat stroke. Therefore, hypotension is the most likely cardiovascular manifestation seen in a client with heat stroke.
