Correct Answer: B

Rationale: Using pillows to keep the client's extremities in a functional position is crucial in preventing joint contractures. This intervention helps maintain proper alignment of the joints and reduces the risk of contractures by preventing prolonged positioning that can lead to muscle shortening. Encouraging the client to perform active range-of-motion exercises (Choice A) is beneficial for maintaining mobility but may not be the most important intervention to prevent joint contractures. Placing the client in a prone position for 30 minutes each day (Choice C) can be helpful for preventing pressure ulcers but is not directly related to preventing joint contractures. Performing passive range-of-motion exercises on the affected side (Choice D) can aid in maintaining joint flexibility but may not be as crucial as using pillows to prevent joint contractures.

Correct Answer: A

Rationale: The correct answer is A. Washing out the feeding bag with warm water once every 24 hours is not sufficient to prevent bacterial growth and can lead to diarrhea. Using hot water may damage the feeding bag. Washing out the feeding bag with soap and water every 24 hours is excessive and may leave residue that could be harmful. Changing the feeding bag every 24 hours is important for preventing infections but does not directly address the issue of diarrhea in this case.

Correct Answer: D

Rationale: To ensure the client's safety during a blood transfusion, it is crucial to verify the blood product with another nurse before administration. This step helps confirm the correct blood type and prevents transfusion reactions. While checking the client's identification and blood type (Choice A) is important, the ultimate responsibility lies with confirming the blood product before administration. Monitoring vital signs (Choice B) is necessary during a transfusion but does not directly address verifying the blood product. Administering blood through a peripheral IV line (Choice C) is a common practice but does not specifically ensure that the correct blood product is being administered, which is essential for the client's safety.

Correct Answer: A

Rationale: The correct answer is A: 'Folic acid should be taken before and after conception.' Folic acid supplementation before and during early pregnancy has been shown to significantly reduce the risk of neural tube defects. Choice B is incorrect because while multivitamin supplements are beneficial during pregnancy, the specific focus for preventing neural tube defects is on folic acid. Choice C is a general statement about a well-balanced diet and does not specifically address neural tube defects. Choice D is incorrect as it focuses on dietary iron, which is important for overall health but not specifically proven to prevent neural tube defects.

Correct Answer: A

Rationale: The correct way to use a cane is for the client to hold it on the stronger side of the body. This positioning allows the cane to provide support to the weaker side, assisting with balance and stability. Placing the cane on the weaker side (Choice B) may not provide adequate support and could lead to an increased risk of falls. Holding the cane in front of the weaker side (Choice C) or in front of the stronger side (Choice D) does not optimize the support and stability needed while walking with a cane.
