1. A healthcare professional is preparing to administer heparin 15,000 units subcutaneously every 12 hours. The available heparin injection is 20,000 units/mL. How many milliliters should the healthcare professional administer per dose?

Correct answer: A

Rationale: To calculate the volume to administer, use the formula: Desired dose / Concentration = Volume to administer. In this case, (15,000 units / 20,000 units/mL) = 0.75 mL. Since the volume needs to be rounded up to the nearest tenth, the correct answer is 0.8 mL. Choice B (0.75 mL) is incorrect because it does not account for rounding up the volume. Choices C (0.5 mL) and D (1 mL) are incorrect as they do not reflect the precise calculation based on the given concentration and desired dose.

2. A client with Addison's disease is being admitted for a total hip arthroplasty. The client takes hydrocortisone. What is the nurse's priority action?

Correct answer: A

Rationale: The priority action for a client with Addison's disease undergoing surgery who takes hydrocortisone is to administer a supplemental dose of hydrocortisone. Acute adrenal insufficiency (adrenal crisis) is a significant risk during surgery due to the stress placed on the body. Supplemental doses help prevent acute adrenal insufficiency and ensure the client's safety during the surgical procedure. Instructing the client about coughing and deep breathing is important post-operatively but not the priority before surgery. Collecting additional information about the client's history of Addison's disease is relevant but not the priority action before surgery. Inserting an indwelling urinary catheter is not the priority action in this scenario.

3. A client is receiving treatment with vincristine. Which of the following findings should the nurse monitor?

Correct answer: B

Rationale: The correct answer is B: Neurotoxicity. Vincristine is known to cause neurotoxicity as an adverse effect due to its impact on the nervous system. Monitoring for neurotoxicity is crucial to detect any signs early. Choices A, C, and D are incorrect. Hyperkalemia is not a typical finding associated with vincristine. Neutropenia is a common side effect of chemotherapy but is not directly related to vincristine. Bradycardia is not a common adverse effect of vincristine.

4. A client has a new prescription for Hydrochlorothiazide. Which of the following information should the nurse include?

Correct answer: A

Rationale: When educating a client about taking Hydrochlorothiazide, the nurse should advise taking the medication with food or after meals to prevent gastrointestinal upset. This medication is a diuretic, so it is important to maintain adequate fluid intake throughout the day to prevent dehydration. Taking it at bedtime is not necessary, and increased swelling of the ankles is not an expected side effect of this medication. Limiting fluid intake in the morning is not necessary and could lead to dehydration, which is a potential side effect of this diuretic.

5. Which of the following conditions is not treated with Lansoprazole?

Correct answer: C

Rationale: Lansoprazole is a proton pump inhibitor used to treat conditions related to excessive stomach acid production, such as Zollinger-Ellison syndrome, gastritis, and reflux. However, it is not indicated for the treatment of hypertension, which is managed using antihypertensive medications. Therefore, the correct answer is C: Hypertension.
