Nursing Elites

1. A nurse reviews an immobilized patient's laboratory results and discovers hypercalcemia. Which condition will the nurse monitor for most closely in this patient?

• A. Hypostatic pneumonia
• B. Renal stones
• C. Pressure ulcers
• D. Thrombus formation

Correct answer: B

Rationale: The correct answer is B: Renal stones. Renal calculi are calcium stones that can form in the renal pelvis or pass through the ureters. Immobilized patients, who have hypercalcemia, are at increased risk for developing renal stones. Monitoring for signs and symptoms of renal stones is crucial in this patient population. Choices A, C, and D are incorrect because although they are potential complications in immobilized patients, they are not directly associated with hypercalcemia and do not match the scenario described in the question.

2. A client receives the influenza vaccine in a clinic. Within 15 minutes after the immunization, the client complains of itchy and watery eyes, increased anxiety, and difficulty breathing. What should be the first action in the sequence of care for this client?

• A. Maintain the airway
• B. Administer epinephrine 1:1000 as ordered
• C. Monitor for hypotension with shock
• D. Administer diphenhydramine as ordered

Correct answer: B

Rationale: In the scenario described, the client is experiencing symptoms of an anaphylactic reaction, a severe allergic response. The priority action in an anaphylactic reaction is to administer epinephrine. Epinephrine helps counteract the severe allergic response, improves breathing difficulties, and maintains airway and circulation. Administering epinephrine takes precedence to stabilize the client's condition. Options A, C, and D may be necessary in the management of anaphylaxis, but the immediate priority is to administer epinephrine to address the life-threatening symptoms.

3. The LPN is instructing a client with high cholesterol about diet and lifestyle modifications. What comment from the client indicates that the teaching has been effective?

• A. If I exercise at least twice weekly for one hour, I will lower my cholesterol.
• B. I need to avoid eating proteins, including red meat.
• C. I will limit my intake of beef to 4 ounces per week.
• D. My blood level of low-density lipoproteins needs to increase.

Correct answer: C

Rationale: The correct answer is C. Limiting intake of beef to 4 ounces per week is an effective dietary modification to manage high cholesterol. Choice A is incorrect because the frequency and duration of exercise alone may not be sufficient to lower cholesterol significantly. Choice B is incorrect as proteins, including lean sources like poultry and fish, can be a part of a healthy diet. Choice D is incorrect as low-density lipoproteins, known as bad cholesterol, should be decreased, not increased, for heart health.

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 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.
