Rationale: In a client with COPD, it is crucial to prevent carbon dioxide retention by avoiding high oxygen levels. As the client's oxygen is running at 6 liters per minute and he is showing signs of oxygen toxicity, such as flushed color and low respirations, the nurse's priority should be to lower the oxygen rate. This action helps prevent worsening the client's condition. Obtaining an EKG, placing the client in high Fowler's position, or taking baseline vital signs are important assessments but addressing the potential oxygen toxicity takes precedence in this scenario.

Correct Answer: C

Rationale: The belief stated in option C is incorrect about acupuncture. Acupuncture is based on the concept of qi flowing through major pathways in the body, known as meridians, rather than nerve clusters. This traditional Chinese medicine practice aims to balance the flow of qi to promote health and healing. Options A, B, and D are consistent with the principles of acupuncture and are not incorrect beliefs. Option A describes the depth and duration of needle placement, option B explains the role of imbalances in qi flow causing illness, and option D outlines how acupuncture helps rebalance energy flow for the body's natural healing mechanisms.

Correct Answer: B

Rationale: The correct answer is B: 'Oozing liquid stool.' In a paralyzed client, oozing liquid stool is a common sign of fecal impaction.

Choice C, 'Continuous rumbling flatulence,' is associated with gas movement in the intestines and not specifically linked to fecal impaction. Choice D, 'Absence of bowel movements,' could be a sign of constipation but does not directly point towards fecal impaction.
