1. When reviewing EBP about the administration of O2 therapy, what is the recommended maximum flow rate for regulating O2 via nasal cannula?

• A. Regulate O2 via nasal cannula no more than 6L
• B. Regulate O2 via nasal cannula no more than 2L
• C. Regulate O2 via nasal cannula no more than 4L
• D. Regulate O2 via nasal cannula no more than 8L

Correct answer: A

Rationale: The correct answer is to regulate O2 via nasal cannula no more than 6L. This flow rate is generally recommended to ensure adequate oxygen delivery without causing discomfort or potential harm to the patient. Choices B, C, and D are incorrect as they suggest flow rates that are either too low (2L, 4L) or too high (8L). A flow rate of 2L might not provide sufficient oxygen, while 4L could be inadequate for some patients. On the other hand, a flow rate of 8L could be excessive and potentially harmful, leading to complications like oxygen toxicity. Therefore, the optimal recommendation is to regulate O2 via nasal cannula at a maximum of 6L to balance effectiveness and safety.

2. When measuring a client's blood pressure, which approach is the priority for a nurse caring for a client with hypertension?

• A. Obtain the blood pressure under the same conditions each time
• B. Use a different arm for each measurement
• C. Measure the blood pressure while the client is standing
• D. Take multiple readings at different times of the day

Correct answer: A

Rationale: The correct approach when measuring a client's blood pressure, especially for a client with hypertension, is to obtain the blood pressure under the same conditions each time. Consistency in measurement conditions helps ensure accurate and comparable blood pressure readings. Using a different arm for each measurement (Choice B) is not ideal as it can lead to variations in readings. Measuring the blood pressure while the client is standing (Choice C) is not the standard practice and may not provide accurate results. Taking multiple readings at different times of the day (Choice D) may be useful for monitoring blood pressure trends but is not the priority when ensuring accurate individual readings.

3. A nurse on a medical-surgical unit is washing her hands prior to assisting with a surgical procedure. Which of the following actions by the nurse demonstrates proper surgical hand-washing technique?

• A. The nurse washes with her hands held higher than her elbows.
• B. The nurse uses an alcohol-based hand rub for 30 seconds.
• C. The nurse scrubs hands and forearms for 2 minutes with soap and water.
• D. The nurse washes her hands with soap and water for only 15 seconds.

Correct answer: A

Rationale: Proper surgical hand-washing technique involves washing with the hands held higher than the elbows. This positioning is essential to ensure proper rinsing and to prevent the risk of contamination. Option B, using an alcohol-based hand rub for 30 seconds, is not specific to surgical hand-washing and is more commonly used for routine hand hygiene. Option C, scrubbing hands and forearms for 2 minutes with soap and water, is excessive and not typically required for routine hand-washing. Option D, washing hands with soap and water for only 15 seconds, is insufficient for thorough surgical hand-washing.

4. A client with a history of diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. What is the most important action for the LPN/LVN to take?

• A. Monitor the client's blood glucose level.
• B. Encourage the client to increase fluid intake.
• C. Administer insulin as prescribed.
• D. Assess the client's urine output.

Correct answer: A

Rationale: The most important action for the LPN/LVN to take when a client with a history of diabetes mellitus experiences symptoms of hyperglycemia such as polyuria, polydipsia, and polyphagia is to monitor the client's blood glucose level. This action helps assess the severity of hyperglycemia and guides further interventions. Encouraging the client to increase fluid intake (Choice B) may exacerbate the symptoms by further diluting the blood glucose concentration. Administering insulin as prescribed (Choice C) should be done based on the healthcare provider's orders and after assessing the blood glucose levels. Assessing the client's urine output (Choice D) is important but not the most immediate action needed in this scenario.

5. A client with type 1 diabetes mellitus is experiencing hypoglycemia. What is the best initial action for the LPN/LVN to take?

• A. Administer glucagon intramuscularly.
• B. Give the client 4 ounces of orange juice.
• C. Give the client a snack containing protein and carbohydrates.
• D. Encourage the client to rest until symptoms resolve.

Correct answer: B

Rationale: The best initial action for a client with type 1 diabetes mellitus experiencing hypoglycemia is to give them 4 ounces of orange juice. Orange juice quickly raises blood glucose levels in a hypoglycemic client. Administering glucagon intramuscularly is not the best initial action for hypoglycemia; it is usually reserved for severe hypoglycemia cases. Giving a snack containing protein and carbohydrates is not as rapid as orange juice in raising blood glucose levels during hypoglycemia. Encouraging the client to rest until symptoms resolve does not address the immediate need to raise blood glucose levels in a hypoglycemic state.
