Nursing Elites

1. A client is being treated for diabetic ketoacidosis (DKA). Which laboratory value would be most concerning?

• A. Blood glucose of 350 mg/dL
• B. Serum bicarbonate of 18 mEq/L
• C. Arterial pH of 7.20
• D. Serum potassium of 5.5 mEq/L

Correct answer: C

Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.

2. A nurse is preparing to check a client's blood pressure. Which of the following actions should the nurse take?

• A. Apply the cuff above the client's antecubital fossa.
• B. Use a cuff with a width that is about 60% of the client's arm circumference.
• C. Have the client sit with their arm resting at the level of their heart.
• D. Release the pressure on the client's arm at a rate of 5 to 6 mm per second.

Correct answer: A

Rationale: The correct action when checking a client's blood pressure is to apply the cuff above the client's antecubital fossa. Placing the cuff above this area allows for an accurate measurement of blood pressure. Choice B is incorrect because the cuff width should be approximately 40% of the arm circumference, not 60%. Choice C is incorrect as the client's arm should rest at heart level, not above it, to ensure an accurate reading. Choice D is incorrect as the pressure on the client's arm should be released at a rate of 2 to 3 mm per second, not 5 to 6 mm per second.

3. The nurse is preparing to administer a subcutaneous injection of insulin to a client with diabetes. What is the best site for the nurse to select for this injection?

• A. Ventrogluteal site
• B. Dorsogluteal site
• C. Deltoid site
• D. Abdomen

Correct answer: D

Rationale: The correct answer is 'D: Abdomen.' The abdomen is the best site for insulin injections as it provides a larger area with consistent absorption rates due to the high vascularity of the area. The subcutaneous tissue in the abdomen allows for a more predictable and consistent absorption of insulin compared to other sites. Ventrogluteal and dorsogluteal sites are not commonly used for insulin injections due to the risk of hitting the sciatic nerve or causing tissue damage. The deltoid site is more commonly used for intramuscular injections rather than subcutaneous injections like insulin.

4. A healthcare professional is administering 1 L of 0.9% sodium chloride to a client who is postoperative and has fluid volume deficit. Which of the following changes should the healthcare professional identify as an indication that the treatment was successful?

• A. Decrease in heart rate
• B. Fluid volume deficit causes tachycardia
• C. Decrease in blood pressure
• D. Increase in respiratory rate

Correct answer: A

Rationale: A decrease in heart rate can indicate that the fluid volume deficit is improving. In cases of fluid volume deficit, the body compensates by increasing the heart rate to maintain adequate perfusion. Therefore, a decrease in heart rate after fluid resuscitation suggests that the body's perfusion status is improving. Choices B, C, and D are incorrect because fluid volume deficit typically causes tachycardia, not a decrease in heart rate, and would not result in a decrease in blood pressure or an increase in respiratory rate as primary signs of improvement.

5. When assessing readiness to learn about insulin self-administration, what indicates the client is ready to learn?

• A. I can concentrate best in the morning.
• B. I feel anxious about learning the process.
• C. I have a lot of questions about insulin.
• D. I am not sure if I can manage this at home.

Correct answer: A

Rationale: The correct answer is A: 'I can concentrate best in the morning.' Readiness to learn is indicated by the client's ability to focus and concentrate, as mentioned in the question. Choice B, 'I feel anxious about learning the process,' indicates apprehension and may hinder the learning process. Choice C, 'I have a lot of questions about insulin,' shows interest but does not directly indicate readiness to learn. Choice D, 'I am not sure if I can manage this at home,' reflects uncertainty and lack of confidence, which may suggest the client is not fully prepared to learn.
