Correct Answer: C

Rationale: It is essential for clients using herbal therapies to obtain herbs from manufacturers with a history of quality control for their supplements. This recommendation is crucial because quality control processes help in maintaining the purity and effectiveness of the herbal supplements. Option A is incorrect as it provides a negative and inaccurate generalization about herbs. Option B is also incorrect as there is existing evidence on the safety and efficacy of certain herbal supplements. Option D is not the most relevant information to offer initially to a client seeking advice on the general use of herbal supplements.

Correct Answer: B

Rationale: The correct answer is B. The administration of opioid analgesics can impair balance and increase the risk of falls, justifying the inclusion of 'Risk for falls' in the client's care plan. Choice A, a recent serum hemoglobin level of 16 g/dL, is not directly related to the risk of falls. Choice C, stooped posture with an unsteady gait, may indicate a risk for falls, but the direct influence of opioid analgesics on balance is more immediate. Choice D, expressed feelings of depression, while important, is not a direct indicator of the immediate risk for falls associated with opioid analgesic use.

Correct Answer: C

Rationale: Setting goals that bring pleasure is appropriate and should be encouraged by the nurse. Choice A is discouraging and focuses on limitations. Choice B jumps to a conclusion and is not in line with the client's statement. Choice D dictates what the client should be doing, which is not respectful of the client's autonomy. Therefore, the most appropriate response is C, as it acknowledges the client's wishes and provides positive reinforcement without perpetuating denial.

Correct Answer: D

Rationale: The nurse should first assess the client's adherence to the original instructions. By asking the client to describe the routine, the nurse can evaluate if the technique is being correctly implemented before considering further interventions. This choice is correct as it focuses on assessing the client's current practice. Option A is incorrect as adding regular exercise may not address the issue with the relaxation technique. Option B is incorrect as determining if the client has been keeping a sleep diary does not directly address the efficacy of the relaxation technique. Option C is incorrect as blindly encouraging the client to continue may not be the best approach without understanding how the technique is being practiced.

Correct Answer: A

Rationale: A decrease in cardiac output can lead to decreased blood flow to the kidneys, resulting in decreased urine output. The kidneys rely on adequate blood supply to filter waste and produce urine. Therefore, a decreased urine output is a common observation when cardiac output is reduced. Choices B, C, and D are incorrect. Increased urine output is not typically associated with decreased cardiac output; flushing of the skin is more related to vasodilation, and hyperventilation is not directly linked to decreased cardiac output.
