Correct Answer: B

Rationale: The correct answer is B: Past experiences. In this scenario, the staff nurse's past experience of having a stillborn infant with Down syndrome is influencing her perception and behavior towards the new mother. This past experience is shaping her emotions, thoughts, and actions, demonstrating how personal experiences can impact communication in healthcare settings. This highlights the importance of self-awareness and reflection to understand how past experiences can influence interactions with patients. Incorrect choices: A: Personal perception - While personal perception plays a role in communication, the key factor in this scenario is the staff nurse's past experience, not just her perception. C: Filtration - Filtration refers to the process of selectively interpreting information. In this case, the staff nurse's behavior is more influenced by her past experience rather than selective filtering of information. D: Preconceived idea - While the staff nurse may have preconceived ideas about individuals with Down syndrome due to her past experience, the primary focus is on her past experience itself rather

Correct Answer: C

Rationale: Rationale for Correct Answer C: Irregular heartbeat is a significant symptom of hyperkalemia, which can be life-threatening. The nurse should evaluate capillary refill to assess perfusion. High potassium levels can affect cardiac function, leading to arrhythmias. Monitoring capillary refill provides insight into tissue perfusion, helping to assess the severity of the condition and guide appropriate interventions. Summary of Incorrect Choices: A: Drowsiness is not a typical symptom of hyperkalemia. Stimulating the patient every 30 minutes does not address the underlying issue. B: Confusion is not a common symptom of hyperkalemia. Asking the patient to state their name and birthdate does not address the cardiac implications of high potassium levels. D: Muscle cramps may occur with hyperkalemia but are not as critical as irregular heartbeat. Elevating the affected limb is not the priority in this situation.

Correct Answer: A

Rationale: Step 1: Define effectiveness and efficiency - Effectiveness is achieving the intended outcome, while efficiency is achieving the outcome with minimal waste. Step 2: Analyze option A - It correctly defines effectiveness as performing the correct test or intervention and efficiency as the wise use of supplies and resources for the desired outcome. Step 3: Justification - The nurse explains that many healthcare providers lack effectiveness, indicating they are not achieving the desired outcomes, which aligns with the definition of effectiveness in option A. Step 4: Summary of incorrect choices - B incorrectly defines efficiency as quick completion of tasks, C confuses efficiency with wastage, and D incorrectly associates efficiency with speed rather than minimal waste.

Correct Answer: C

Rationale: The correct answer is C: phenomenology. Phenomenology focuses on exploring and understanding individuals' lived experiences to uncover the essence of a phenomenon. In this case, the nurse is interested in understanding the meaning of surviving polio from the perspective of those diagnosed with the disease. By reflecting on the data and identifying common themes, the researcher aims to capture the essence of the human experience of surviving polio. Grounded theory (A) is a method used to develop theories from data, not necessarily focusing on the lived experience. Ethnography (B) involves studying cultures and societies, which is not directly aligned with understanding individual experiences. Case study (D) typically focuses on in-depth analysis of a specific individual or group, rather than exploring common themes across individuals' experiences.

Correct Answer: B

Rationale: The correct answer is B because the Affordable Care Act of 2011 aimed to provide health care benefits to millions who were previously uninsurable or unable to afford insurance. This is in line with the main goal of the act, which was to increase access to affordable health care for Americans. Choice A is incorrect as the act does not mandate educational requirements for nurses. Choice C is incorrect as the act does not specifically cap the amount that hospitals and physicians can charge for procedures. Choice D is incorrect as the act focuses on expanding access to health insurance rather than directly subsidizing private insurance companies to reduce costs for individuals with chronic illnesses.
