A public health nurse is planning a prenatal program to ensure that resources are equally available to all community members. Which of the following ethical principles is the nurse practicing?

Rationale:

A. "Biofeedback requires concentration to control physiological responses.": Biofeedback is a technique that helps clients gain voluntary control over involuntary bodily functions, such as muscle tension, heart rate, or skin temperature. Through focused concentration and real-time feedback from monitoring devices, clients learn to reduce stress and prevent migraine triggers.

B. “Biofeedback improves energy flow through soft tissue manipulation to increase circulation.": This description aligns more with massage or energy-based therapies, not biofeedback. Biofeedback does not involve physical manipulation of tissues but relies on monitoring and controlling physiological responses through mental focus.

C. "Biofeedback uses herbs to reduce inflammation": Herbal therapy is a complementary approach unrelated to biofeedback. Biofeedback does not incorporate herbal remedies and instead emphasizes self-regulation techniques using bio-monitoring equipment.

D. “Biofeedback stimulates certain pressure points to relax muscles": Stimulating pressure points is characteristic of acupressure or acupuncture, not biofeedback. While muscle relaxation is a goal of biofeedback, it is achieved through self-regulation and feedback, not external stimulation.

Rationale:

A. Hypotension: While hypotension can indicate shock or fluid imbalance, it may develop secondary to other complications. It is concerning but not necessarily the earliest indicator of an acute pulmonary embolism.

B. Dyspnea: Sudden or worsening shortness of breath is the most immediate sign of a possible pulmonary embolism, which is life-threatening. Prompt recognition and reporting are critical to initiate interventions such as oxygen therapy, anticoagulation, or advanced imaging.

C. Dry cough: A dry cough may accompany a pulmonary embolism but is nonspecific and less urgent. It does not indicate immediate compromise compared with respiratory distress or hypoxia.

D. Tachycardia: Elevated heart rate can be an early sign of stress or hypoxia but is less specific than dyspnea. Tachycardia warrants monitoring, but shortness of breath takes priority for immediate action.
