Nursing Elites

1. A nurse is assessing a client who has diabetic ketoacidosis (DKA). Which of the following laboratory findings should the nurse expect?

• A. Blood glucose 120 mg/dL
• B. pH 7.32
• C. HCO3 25 mEq/L
• D. PaCO2 48 mm Hg

Correct answer: B

Rationale: The correct answer is B. A pH of 7.32 indicates metabolic acidosis, which is a hallmark of diabetic ketoacidosis (DKA). In DKA, blood glucose levels are typically elevated, bicarbonate levels are often low, and there is a compensatory respiratory response leading to a decrease in PaCO2. Option A is incorrect because a blood glucose level of 120 mg/dL is within the normal range and not indicative of DKA. Option C is incorrect because an HCO3 level of 25 mEq/L is not typically seen in DKA where bicarbonate levels are usually lower. Option D is incorrect because a PaCO2 of 48 mm Hg would not be expected in DKA; it would typically be lower due to compensatory respiratory alkalosis.

2. A nurse is using Naegele’s rule to calculate the expected delivery date for a client whose last menstrual period was in October. What is the expected date?

• A. 711
• B. 1011
• C. 411
• D. 1211

Correct answer: A

Rationale: Using Naegele’s rule, to calculate the expected delivery date, you add one year, subtract three months, and add seven days to the first day of the last menstrual period. If the last menstrual period was in October, adding one year gives October of the following year. Subtracting three months gives July, and adding seven days gives the expected delivery date of July 11th. Therefore, the correct answer is 711. Choice B (1011) is incorrect as it doesn't follow Naegele’s rule calculations. Choices C (411) and D (1211) are also incorrect as they do not align with the correct application of Naegele’s rule.

3. A healthcare professional is preparing to administer heparin 8,000 units subcutaneously every eight hrs. The amount available is heparin injection 10,000 units/mL. How many milliliters should the healthcare professional administer per dose?

• A. 0.7 mL
• B. 0.8 mL
• C. 1.0 mL
• D. 1.2 mL

Correct answer: B

Rationale: Calculation: 8000 units / 10,000 units per mL = 0.8 mL. To correctly administer the prescribed dose of 8000 units, the healthcare professional should draw up 0.8 mL from the 10,000 units/mL vial. Options A, C, and D are incorrect as they do not accurately reflect the calculation based on the available concentration of heparin.

4. A client is prescribed metronidazole for a bacterial infection. Which of the following should the nurse teach the client?

• A. Avoid alcohol while taking this medication
• B. It is safe to take during pregnancy
• C. Monitor for increased appetite
• D. It can cause hair loss

Correct answer: A

Rationale: The correct answer is A: 'Avoid alcohol while taking this medication.' Metronidazole can cause a disulfiram-like reaction with alcohol, leading to symptoms like nausea, vomiting, flushing, and headache. Therefore, clients should be instructed to avoid alcohol consumption. Choice B is incorrect because metronidazole is not considered safe during pregnancy, especially in the first trimester. Choice C is incorrect as metronidazole is not known to cause increased appetite. Choice D is also incorrect as hair loss is not a common side effect of metronidazole.

5. A client with hepatic encephalopathy is being educated about their diet by a nurse. Which of the following food selections indicates that the client understands the teaching?

• A. A sandwich and a milkshake
• B. Rice with black beans
• C. Cottage cheese and tuna on lettuce
• D. A three-egg omelet with low-sodium ham

Correct answer: B

Rationale: The correct answer is B: Rice with black beans. Clients with hepatic encephalopathy should limit protein intake to prevent the buildup of ammonia. Plant-based proteins are preferred over animal-based proteins in this condition. Rice with black beans provides a good balance of nutrients and is a suitable choice for a client with hepatic encephalopathy. Choices A, C, and D are incorrect because they contain animal-based proteins, which should be limited in clients with hepatic encephalopathy.
