Nursing Elites

1. A client with type 1 diabetes mellitus presents with nausea, vomiting, and abdominal pain. The nurse suspects diabetic ketoacidosis (DKA). Which of the following lab findings would confirm this diagnosis?

• A. Serum glucose of 180 mg/dL
• B. Serum bicarbonate of 22 mEq/L
• C. Blood pH of 7.25
• D. Urine specific gravity of 1.020

Correct answer: C

Rationale: A blood pH of 7.25 is a critical finding in diabetic ketoacidosis (DKA) as it indicates metabolic acidosis, which is a hallmark of this condition. In DKA, there is an accumulation of ketones in the blood, leading to increased acidity. The serum glucose level is typically elevated in DKA, often exceeding 250 mg/dL. A serum bicarbonate level less than 18 mEq/L is usually seen in DKA due to the metabolic acidosis. Urine specific gravity is not a specific indicator for DKA and may vary depending on the individual's hydration status. Therefore, the correct lab finding that confirms DKA in this scenario is a blood pH of 7.25.

2. A client with type 2 DM is being treated with metformin (Glucophage). The nurse should include which instruction when teaching the client about this medication?

• A. Take the medication with meals.
• B. Take the medication on an empty stomach.
• C. Take the medication before bedtime.
• D. Avoid taking the medication if you miss a meal.

Correct answer: A

Rationale: The correct instruction for a client taking metformin (Glucophage) is to take the medication with meals. This helps reduce gastrointestinal side effects and improves absorption. Choice B is incorrect because taking metformin on an empty stomach can increase the risk of side effects. Choice C is incorrect as there is no specific recommendation to take metformin before bedtime. Choice D is incorrect as missing a meal should not lead to avoiding the medication, but the client should take it with the next meal as prescribed.

3. A client with DM is taking regular and NPH insulin every morning. The nurse should provide which instruction to the client?

• A. Take the regular insulin first, then the NPH insulin.
• B. Take the NPH insulin first, then the regular insulin.
• C. Mix the insulins in a separate syringe.
• D. Take the regular insulin first and immediately follow it with the NPH insulin.

Correct answer: A

Rationale: The correct instruction for the client is to take the regular insulin first, then the NPH insulin. Regular insulin should be administered before NPH insulin to prevent contamination and maintain the potency of each insulin type. Choice B is incorrect because NPH insulin should not be taken before regular insulin. Mixing the insulins in a separate syringe, as suggested in choice C, is not recommended as it may alter the effectiveness of the insulins. Choice D is also incorrect as taking the regular insulin first and immediately following it with NPH insulin is not the recommended administration sequence.

4. Which of the following statements is true regarding ethical principles and laws?

• A. The government enforces ethics.
• B. Laws establish standards that aid in decision-making.
• C. Ethics are highly specific.
• D. Ethical principles can serve as the foundation for laws.

Correct answer: D

Rationale: The correct answer is D. Ethical principles can influence the creation of laws but are not equivalent to laws themselves. Laws are established by governing bodies to provide a framework for society, whereas ethical principles guide individuals' moral conduct. Choice A is incorrect because governments enforce laws, not ethics. Choice B is incorrect as laws set legal standards rather than ethical ones. Choice C is incorrect because ethics are principles that guide behavior but are not necessarily highly specific.

5. Nurse Perry is caring for a female client with type 1 diabetes mellitus who exhibits confusion, light-headedness, and aberrant behavior. The client is still conscious. The nurse should first administer:

• A. I.M. or subcutaneous glucagon.
• B. I.V. bolus of dextrose 50%.
• C. 15 to 20 g of a fast-acting carbohydrate such as orange juice.
• D. 10 U of fast-acting insulin.

Correct answer: C

Rationale: For a conscious client with hypoglycemia, the initial treatment should involve administering 15 to 20 g of a fast-acting carbohydrate, such as orange juice. This helps rapidly raise the client's blood glucose levels. Choices A and D are incorrect as administering glucagon or fast-acting insulin is not the first-line treatment for hypoglycemia in a conscious client. Choice B, an I.V. bolus of dextrose 50%, is a more invasive and aggressive intervention that is not typically indicated for a conscious client with hypoglycemia.
