1. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?

• A. 11,000 units.
• B. 13,000 units.
• C. 15,000 units.
• D. 17,000 units.

Correct answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

2. A nurse obtains a prescription for wrist restraints for a client who is trying to pull out his NG Tube. Which of the following actions should the nurse take?

• A. Remove the restraints every 4 hours.
• B. Attach the restraints securely to the side of the client's bed.
• C. Apply the restraints to allow as little movement as possible.
• D. Allow room for two fingers to fit between the client's skin and the restraints.

Correct answer: D

Rationale: When using wrist restraints, it is important to allow room for two fingers to fit between the client's skin and the restraints. This practice ensures proper circulation and comfort for the client while still providing the necessary level of security. Choice A is incorrect because removing restraints every 4 hours may compromise the effectiveness of restraint use. Choice B is incorrect as restraints should not be attached to the side of the bed where they could cause harm or be tampered with by the client. Choice C is incorrect because allowing minimal movement may lead to discomfort and compromise proper circulation.

3. A health care provider has prescribed isoniazid (Laniazid) for a client. Which instruction should the LPN give the client about this medication?

• A. Prolonged use does not typically cause dark concentrated urine.
• B. It is not necessary to take the medication on an empty stomach for optimal absorption.
• C. Avoid taking the medication with aluminum hydroxide to minimize GI upset.
• D. Drinking alcohol daily can cause drug-induced hepatitis.

Correct answer: D

Rationale: The correct answer is D. When taking isoniazid, alcohol consumption should be avoided as it can increase the risk of liver damage, potentially leading to drug-induced hepatitis. Choices A, B, and C are incorrect. Prolonged use of isoniazid does not typically cause dark concentrated urine; it is not necessary to take the medication on an empty stomach for optimal absorption; and it is not recommended to take isoniazid with aluminum hydroxide to minimize GI upset.

4. A client is being admitted to a same-day surgery center for an exploratory laparotomy procedure. The surgeon asks the nurse to witness the signing of the preoperative consent form. In signing the form as a witness, the nurse affirms that:

• A. The client understands the procedure
• B. The signature on the preoperative consent form is the client’s
• C. The procedure has been explained
• D. The client is aware of potential complications

Correct answer: B

Rationale: The correct answer is B because as a witness, the nurse's primary responsibility is to confirm that the signature on the preoperative consent form belongs to the client. The nurse is not confirming the client's understanding of the procedure (Choice A), but rather the authenticity of the signature. Choice C is incorrect because the nurse is not responsible for verifying that the procedure has been explained, but rather confirming the client's signature. Similarly, Choice D is incorrect because the nurse's role as a witness is not to ensure the client is aware of potential complications, but to verify the signature.

5. A client is scheduled for an appendectomy and has given informed consent. Which statement by the client should the nurse address first preoperatively?

• A. “I am afraid to walk if it hurts too much.”
• B. “I don’t understand why I need this surgery.”
• C. “I don’t want my family helping me after the surgery.”
• D. “I am afraid the scar will make me look disfigured.”

Correct answer: B

Rationale: The nurse should address the client's lack of understanding regarding the need for surgery first. Ensuring that the client comprehends the rationale for the procedure is essential for informed consent. Choices A, C, and D, while important, do not directly impact the client's understanding of the necessity of the surgery and can be addressed after clarifying the reason for the procedure.
