Correct Answer: B

Rationale: The correct answer is B: '12% fewer urinary tract infections.' Tracking infections, such as UTIs, is crucial in assessing care quality improvements as the reduction in infections indicates better infection control practices and overall quality of care. Choices A, C, and D are incorrect. Increased admissions (Choice A) do not directly reflect improvements in care quality. Increased mortality rate (Choice C) is a negative outcome and demonstrates a decline in care quality. No changes in staffing (Choice D) do not provide direct evidence of care quality improvements.

Correct Answer: C

Rationale: When caring for a client diagnosed with delirium, the most important condition for the nurse to investigate is prescription drug intoxication. Delirium can be caused by various factors, and prescription drug intoxication is a common reversible cause. Investigating this factor first is crucial to identify and address the underlying cause promptly. Choices A, B, and D are less likely to be directly associated with delirium compared to prescription drug intoxication. While cancer, impaired hearing, and heart failure can have their complications and effects, they are not typically the primary causes of delirium in a client.

Correct Answer: B

Rationale: The correct instruction when using a cane due to leg weakness is to maintain two points of support on the floor at all times. This provides stability and support while walking. Choice A is incorrect because the cane should be used on the weaker side to provide assistance. Choice C is incorrect as the cane and weak leg should move together for support. Choice D is incorrect as advancing the cane too far with each step may compromise balance and stability.

Correct Answer: A

Rationale: The correct answer is A: Increase in frequency of swallowing. After rhinoplasty, an increase in frequency of swallowing may indicate possible bleeding, which requires immediate action by the nurse. The client could be experiencing postoperative bleeding, and prompt intervention is necessary to prevent complications. Choice B, moderate sanguineous drainage on the drip pad, is expected in the immediate postoperative period and does not require immediate action unless it becomes excessive. Choice C, bruising to the face, is a common postoperative finding and does not require immediate action unless it is excessive or affects the airway. Choice D, absent gag reflex, would not be expected immediately following rhinoplasty and would require intervention, but the manifestation of increased swallowing frequency is a higher priority due to its association with potential bleeding.

Correct Answer: A

Rationale: Ethics is the correct answer because it specifically deals with the study of conduct and character. Ethics is a branch of philosophy that involves systematizing, defending, and recommending concepts of right and wrong conduct. While justice and morals are related to ethical considerations, they do not directly represent the study of conduct and character. Non-maleficence is a principle in medical ethics related to avoiding harm.
