Correct Answer: B

Rationale: The correct statement is, 'I need to wash my hair before the test.' Washing the hair is necessary to remove hair products that could interfere with electrode attachment to the scalp. Restricting food or drink is not required, except for avoiding caffeinated beverages. Removing metal jewelry is unnecessary for an electroencephalography procedure. Aspirin does not need to be avoided before the test; medications like anticonvulsants, tranquilizers, barbiturates, and sedatives are the ones that might need to be held.

Correct Answer: B

Rationale: The correct answer is B: Inability to communicate pain. In this scenario, the client's aphasia prevents them from verbally expressing their pain, which can lead to inadequate pain management if the healthcare team is not vigilant. The nurse must use alternative methods to assess and address the client's pain. Choices A, C, and D, although important considerations in postoperative care, do not directly relate to the client's ability to communicate pain, which is crucial for effective pain management in this case.

Correct Answer: D

Rationale: The proper hand position for performing chest percussion is to cup the hands. Cupping the hands helps produce a vibration that aids in loosening respiratory secretions effectively. This technique is essential for therapeutic chest physiotherapy. Using the side of the hands, flattening the hands, or spreading the fingers of both hands do not generate the necessary vibration required for chest percussion. These hand positions are not considered proper techniques in this context and may not provide the desired therapeutic effect.

Correct Answer: B

Rationale: The purpose of the hydraulic lift, also known as the Hoyer lift, is to facilitate safe transfers for clients who cannot stand or are extremely obese. It is specifically designed for assisting clients who are unable to stand and for those who are too heavy for healthcare workers to lift safely. Choice A is incorrect because the primary purpose of a hydraulic lift is not related to orthopedic surgery. Choice C is incorrect because it is too broad and does not capture the specific use of the hydraulic lift. Choice D is incorrect because the lift is not solely for clients with special needs but rather for those who cannot stand or are extremely obese.

Correct Answer: C

Rationale: The correct answer is 'The main therapeutic goals are comfort and better quality of life.' This statement reflects a proper understanding of palliative care, which focuses on improving the patient's quality of life and providing comfort. It does not necessarily mean a prognosis of less than 6 months or require hospitalization. Choice A is incorrect because palliative care can be provided regardless of the prognosis. Choice B is wrong as palliative care can be administered in various settings, not just hospitals. Choice D is inaccurate as palliative care aims to improve symptoms and quality of life, so medications may be adjusted but not necessarily stopped.
