Nursing Elites

1. A home health nurse is discussing the dangers of carbon monoxide poisoning with a client. Which of the following information should the nurse include?

• A. Carbon monoxide does not have a distinct odor.
• B. Water heaters should be inspected every 5 years.
• C. The lungs are not damaged from carbon monoxide inhalation.
• D. Carbon monoxide binds with hemoglobin in the body.

Correct answer: D

Rationale: The correct answer is D: 'Carbon monoxide binds with hemoglobin in the body.' Carbon monoxide is an odorless, colorless gas, so it does not have a distinct odor (Choice A). While regular inspection of appliances like water heaters is important for safety, it is not directly related to carbon monoxide poisoning (Choice B). Carbon monoxide primarily affects the cardiovascular system by binding with hemoglobin, reducing the blood's ability to carry oxygen, rather than causing direct lung damage (Choice C). Understanding how carbon monoxide binds with hemoglobin is crucial in recognizing the mechanism of poisoning and its potential consequences.

2. 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.

3. A nurse is receiving the prescription for a client who is experiencing dysphagia following a stroke. Which of the following prescriptions should the nurse clarify?

• A. Dietitian consult
• B. Speech therapy referral
• C. Oral suction at the bedside
• D. Clear liquids

Correct answer: D

Rationale: The correct answer is D: 'Clear liquids.' Clients with dysphagia following a stroke are at risk of aspiration, and clear liquids have a higher risk of aspiration compared to thickened liquids or pureed foods. Therefore, the nurse should clarify the prescription for clear liquids to prevent potential harm to the client. Choices A, B, and C are appropriate interventions for a client with dysphagia following a stroke. A dietitian consult can help modify the client's diet for safe swallowing, speech therapy can assist in improving swallowing function, and oral suction at the bedside helps maintain airway patency and prevents aspiration.

4. When explaining the fecal occult blood testing procedure to a client, which of the following information should be included?

• A. Eating more protein is not necessary before testing.
• B. Multiple stool specimens may be required for testing.
• C. A red color change indicates a positive test.
• D. The specimen must not be contaminated with urine.

Correct answer: D

Rationale: The correct answer is D. When performing fecal occult blood testing, it is crucial to inform the client that the specimen must not be contaminated with urine to prevent false results. Choices A and B are incorrect because eating more protein is not required before testing, and multiple stool specimens may be necessary for accurate results, respectively. Additionally, regarding choice C, a red color change, not blue, indicates a positive test result, making it an incorrect option.

5. While reviewing the medical records of a client with a pressure ulcer, a nurse should expect which of the following findings?

• A. Albumin level of 3 g/dL
• B. Hemoglobin level of 12 g/dL
• C. WBC count of 6,000/mm³
• D. Blood glucose level of 100 mg/dL

Correct answer: A

Rationale: An albumin level below 3.5 g/dL indicates protein deficiency, which can impair wound healing and contribute to pressure ulcer formation. Hemoglobin level and WBC count are not directly associated with pressure ulcers. Blood glucose level, while important for overall health, is not specifically linked to pressure ulcer development.
