Correct Answer: A

Rationale: The correct answer is A: experimental design. In an experimental design, the researcher manipulates one variable (aromatherapy vs. acupuncture) to observe its effect on another variable (stress). Without a control group, it is impossible to establish a baseline for comparison. A control group is essential to isolate the effects of the treatment from other variables. Quasi-experimental designs lack random assignment, surveys are used to gather data rather than test hypotheses, and meta-analyses involve combining and analyzing results from multiple studies.

Correct Answer: A

Rationale: The correct answer is A: Magnet therapy. Magnet therapy is contraindicated in pregnancy due to the risk of unknown effects on the fetus. Magnets may interfere with the body's natural magnetic fields, potentially causing harm to the developing baby. Aromatherapy (B), imagery (C), and therapeutic touch (D) are generally considered safe during pregnancy when performed by trained professionals and with appropriate precautions. Aromatherapy uses essential oils, imagery involves mental visualization techniques, and therapeutic touch uses energy-based techniques that do not pose significant risks to the pregnant woman or the fetus.

Correct Answer: B

Rationale: The correct answer is B because maintaining eye contact while focusing on the patient's description of pain level and location demonstrates active listening. This non-verbal communication shows empathy and attentiveness to the patient's concerns. Choice A focuses on providing information rather than actively listening. Choice C involves personalizing the situation rather than focusing on the patient's needs. Choice D involves agreeing with the patient's decision rather than actively listening to understand their perspective.

Correct Answer: C

Rationale: The correct answer is C: autonomy. Autonomy refers to a patient's right to make their own decisions about their healthcare, including the right to accept or refuse treatment. In this scenario, the 13-year-old female has expressed her desire to have the baby and give it up for adoption. By respecting her autonomy, healthcare providers must support her decision, even if it goes against her father's wishes. A: Deontology is a moral theory that emphasizes the importance of following moral rules and duties. While autonomy is a principle within deontology, the main focus in this scenario is on respecting the patient's autonomy rather than following a specific moral rule. B: Veracity refers to the principle of truth-telling. While honesty is important in healthcare, the main issue in this scenario is respecting the patient's autonomy rather than truth-telling. D: Beneficence refers to the duty to do good and promote the well-being of the patient. In this scenario, respecting the patient's autonomy is

Correct Answer: B

Rationale: The correct answer is B: length of hospital stay. DRGs aim to reduce healthcare costs by incentivizing hospitals to provide efficient care and discharge patients sooner. Shortening the length of hospital stay helps decrease overall healthcare expenses without compromising the quality of care. Choices A, C, and D are incorrect because DRGs focus on the duration of hospitalization, not necessarily on hospital admission rates, outpatient services, or specialty groups. Shortening hospital stays is a more direct way to control costs within the inpatient setting.
