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 client who is 5'5" tall and weighs 200 pounds is scheduled for surgery the next day. What question is most important for the LPN to include during the preoperative assessment?

• A. What is your daily calorie consumption?
• B. What vitamin and mineral supplements do you take?
• C. Do you feel that you are overweight?
• D. Will a clear liquid diet be okay after surgery?

Correct answer: B

Rationale: During the preoperative assessment, it is crucial for the LPN to inquire about the client's intake of vitamin and mineral supplements. This is important because certain supplements can have effects on coagulation, wound healing, and overall surgical outcomes. Asking about daily calorie consumption (Choice A) is not as pertinent as inquiring about vitamin and mineral supplements in this context. Questioning the client about feeling overweight (Choice C) may not directly impact the surgical outcome compared to the effects of supplements. Inquiring about the post-surgery diet (Choice D) is relevant but not as critical as understanding the client's supplement intake.

3. When interviewing the parents of a child with asthma, what information about the child's environment should be gathered most importantly?

• A. Household pets
• B. New furniture
• C. Lead-based paint
• D. Plants such as cactus

Correct answer: A

Rationale: When assessing a child with asthma, it is crucial to gather information about potential triggers in their environment. Household pets, such as cats or dogs, are common triggers for asthma attacks due to pet dander and saliva. This information is essential to identify if exposure to pets at home could be exacerbating the child's asthma symptoms. Choices B, C, and D are less relevant in the context of asthma triggers. New furniture, lead-based paint, and plants like cactus are not typically primary triggers for asthma attacks compared to common allergens like pet dander.

4. A client with diabetes mellitus is learning to self-administer insulin. Which action by the client indicates the need for further teaching?

• A. The client rotates injection sites on the abdomen.
• B. The client draws up the insulin dose after warming the vial to room temperature.
• C. The client pinches the skin before injecting the insulin.
• D. The client injects the insulin at a 90-degree angle.

Correct answer: B

Rationale: Drawing up insulin after warming the vial to room temperature indicates a need for further teaching, as insulin should be at room temperature for administration. Choice A is correct as rotating injection sites helps prevent lipodystrophy. Choice C is correct as pinching the skin helps ensure proper subcutaneous injection. Choice D is correct as injecting insulin at a 90-degree angle is the recommended technique for subcutaneous injections.

5. The client is being taught about the use of syringes and needles for home administration of medications. Which action by the client indicates an understanding of standard precautions?

• A. Remove the needle after discarding used syringes
• B. Wear gloves while disposing of the needle and syringe
• C. Wear a face mask during medication administration
• D. Wash hands before handling the needle and syringe

Correct answer: D

Rationale: The correct answer is D. Washing hands before handling the needle and syringe is a critical step in infection control and adherence to standard precautions. Clean hands help prevent the transfer of microorganisms and reduce the risk of infection. Choices A, B, and C do not directly relate to standard precautions. Removing the needle after discarding used syringes (Choice A) can increase the risk of needlestick injuries. Wearing gloves while disposing of the needle and syringe (Choice B) is important for personal protection but does not specifically address standard precautions. Wearing a face mask during medication administration (Choice C) is not directly related to handling syringes and needles, which are more pertinent to standard precautions.
