Nursing Elites

1. A client with congestive heart failure (CHF) is receiving furosemide (Lasix). Which laboratory value should the LPN monitor closely while the client is taking this medication?

• A. Sodium
• B. Potassium
• C. Calcium
• D. Magnesium

Correct answer: B

Rationale: The LPN should monitor potassium levels closely while the client is taking furosemide (Lasix) due to the medication's potential to cause hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through increased urine output. Hypokalemia can result in serious complications such as cardiac dysrhythmias. Monitoring sodium levels (choice A) is important but not as critical as monitoring potassium in this context. Calcium (choice C) and magnesium (choice D) levels are not typically affected by furosemide and are not the priority for monitoring in this scenario.

2. When changing the client's dressing, which observation should the nurse report to the client's surgeon for a client recovering from an appendectomy for a ruptured appendix with a surgical wound healing by secondary intention?

• A. A halo of erythema on the surrounding skin
• B. Presence of serous drainage
• C. Edema around the wound
• D. Absence of granulation tissue

Correct answer: A

Rationale: A halo of erythema on the surrounding skin may indicate an infection or inflammation of the wound site, which is critical to report to the surgeon. Erythema, redness, and warmth are signs of inflammation that could potentially be a sign of an infected wound. Serous drainage is a common and expected finding in healing wounds, indicating a normal healing process. Edema around the wound might be expected due to the body's response to tissue injury. The absence of granulation tissue in a wound healing by secondary intention may not be an immediate concern as it forms during the later stages of wound healing.

3. A charge nurse is observing a newly licensed nurse prepare a sterile field. Which of the following actions should the charge nurse identify as contaminating the sterile field?

• A. The nurse opens the sterile field on a wet surface.
• B. The nurse turns away from the sterile field.
• C. The nurse uses a non-sterile glove to touch the sterile field.
• D. The nurse touches the edge of the sterile drape with her hand.

Correct answer: A

Rationale: The correct answer is A. Opening the sterile field on a wet surface contaminates it, rendering it unsafe for use. Moisture can carry microorganisms that can compromise the sterility of the field. Choice B is incorrect because turning away from the sterile field alone does not necessarily contaminate it unless the nurse touches non-sterile items. Choice C is incorrect because using a non-sterile glove to touch the sterile field directly introduces contaminants. Choice D is incorrect as touching the edge of the sterile drape with a hand may not necessarily contaminate the entire field, unlike opening it on a wet surface.

4. A healthcare professional is preparing to administer gentamicin 2 mg/kg via IV bolus to a client who weighs 220 lb. How many mg should the healthcare professional administer?

• A. 200 mg
• B. 100 mg
• C. 160 mg
• D. 180 mg

Correct answer: C

Rationale: To calculate the dosage correctly, the weight in pounds must first be converted to kilograms. 220 lb / 2.2 = 100 kg. Then, multiply the weight in kg by the dosage of 2 mg/kg: 2 mg/kg × 100 kg = 200 mg. Therefore, the correct dosage to administer is 200 mg, which is closest to option A. Option C (160 mg) is incorrect because it does not match the calculated dosage. Options B (100 mg) and D (180 mg) are also incorrect as they do not align with the correct calculation.

5. The caregiver is teaching parents about accidental poisoning in children. Which point should be emphasized?

• A. Call the Poison Control Center as soon as the situation is identified
• B. Empty the child's mouth in any case of possible poisoning
• C. Have the child move minimally if a toxic substance was inhaled
• D. Do not induce vomiting if the poison is a hydrocarbon

Correct answer: B

Rationale: The correct answer is to emphasize emptying the child's mouth in any case of possible poisoning. This action is crucial to prevent further ingestion of the poisonous substance. Choice A is incorrect because calling the Poison Control Center should be one of the first steps, not waiting until the situation is identified. Choice C is incorrect as moving the child may spread or exacerbate the effects of the toxic substance. Choice D is incorrect because inducing vomiting can be harmful if the poison is a hydrocarbon, as it may lead to aspiration.
