Correct Answer: B

Rationale: The best argument for lower patient-to-nurse ratios is that they decrease patient mortality. Choice A is incorrect because having more patients can lead to increased workload and decreased attention per patient. Choice C is incorrect as adequate nurse levels can indeed impact the prevalence of infections. Choice D is incorrect as community nursing ratios can impact MRSA rates due to potential transmission risks in healthcare settings.

Correct Answer: B

Rationale: The correct answer is to initiate cardiac monitoring. Severe hypokalemia can lead to life-threatening arrhythmias, making cardiac monitoring the priority to detect and manage any cardiac complications. Starting oxygen, seizure precautions, or bed rest are not the immediate priority actions for severe hypokalemia.

Correct Answer: A

Rationale: The nurse should address the inadequate food supply first as it directly impacts the client's health post-discharge. Proper nutrition is crucial for recovery after surgery, especially such as coronary artery bypass grafting. While low pain tolerance, limited social support, and decreased self-esteem are all important issues to address, addressing the client's nutritional needs is the priority in this scenario to ensure optimal recovery and healing.

Correct Answer: A

Rationale: The nurse manager is utilizing the competing conflict-resolution strategy. Competing involves making decisions based on one's preferences without considering the opinions or feelings of others. In this scenario, the nurse manager is unilaterally implementing changes despite opposition, demonstrating a competitive approach. Collaborating involves working together to find a mutually beneficial solution, compromising involves finding a middle ground acceptable to both parties, and cooperating involves working together towards a shared goal. These options are not applicable in this situation as the nurse manager is imposing her preferred changes without regard for others' input.

Correct Answer: B

Rationale: Patient advocacy in nursing entails ensuring that patients' rights and preferences are respected. This involves advocating for the patients' best interests, supporting informed decision-making, and safeguarding their autonomy. Choice A is incorrect because patient advocacy focuses on the patient's needs, not the healthcare team's. Choice C is incorrect as patient advocacy aims to empower patients and enhance their autonomy rather than limiting it. Choice D is incorrect since patient advocacy goes beyond clinical procedures to encompass holistic care that addresses the patients' preferences and rights.
