Rationale: Role overload occurs when a person feels overwhelmed by the demands placed upon them.

Correct Answer: B

Rationale: Severe pain can be a significant distraction and impediment to the learning process. When a client is experiencing severe pain, their focus and attention are primarily directed towards managing the pain, making it difficult for them to absorb and retain new information effectively. Options A, C, and D, although important considerations in a healthcare setting, do not directly impact the client's ability to learn in the same way that severe pain does. Not feeling well, low blood pressure, and anxiety are all factors that can be addressed or managed to facilitate learning, unlike severe pain which can significantly hinder the learning process.

Correct Answer: D

Rationale: The correct answer is D. Purulent drainage around the insertion site of the feeding tube indicates an infection, which requires immediate attention. This may be a sign of a serious complication that needs prompt nursing intervention to prevent further complications or deterioration in the client's condition. Choices A, B, and C do not indicate an immediate threat to the client's health. While option A highlights the infusion rate of the feeding, it does not pose an immediate risk compared to the presence of purulent drainage indicating infection.

Correct Answer: A

Rationale: The correct procedure when obtaining a urine specimen from an indwelling catheter for culture and sensitivity is to cleanse the entry port before withdrawing urine. This step helps reduce the risk of contamination and ensures the accuracy of the results. Option B is incorrect because using a sterile syringe to collect urine from the collection bag is not the recommended method for obtaining a catheter specimen. Option C is incorrect as obtaining the specimen from the drainage tubing is not the appropriate technique for collecting a urine sample from an indwelling catheter. Option D is incorrect because replacing the catheter before obtaining the specimen is not necessary and may introduce unnecessary complications.

Correct Answer: A

Rationale: The correct instruction to prevent back injuries while lifting is to spread your feet apart to provide a wide base of support. This helps in maintaining stability and reduces the risk of back injury. Choice B is incorrect as lifting objects with your back straight and using your legs is the recommended technique. Choice C is incorrect because assistive devices can actually help prevent back injuries by providing support. Choice D is incorrect as bending at the waist to reach objects can strain the back muscles and increase the risk of injury.
