Minute ventilation increases primarily due to an increase in tidal volume. Hypocapnia (PaCO2 of 30 mm Hg) is therefore common in late pregnancy. A PaCO2 of 35 to 40 mm Hg may indicate impending respiratory failure during pregnancy.

Correct Answer: D

Rationale: The correct answer is D because assessing the airway, breathing, and circulation (ABC) should be combined with a thorough clinical examination, including imaging studies like AP and odontoid X-rays or CT scans, to evaluate potential spinal cord injuries comprehensively. This approach allows for a more accurate diagnosis and appropriate management. Choices A, B, and C are incorrect because performing ABC assessments alone may not provide sufficient information to evaluate spinal cord injuries in trauma patients, and imaging studies are necessary to rule out or confirm such injuries.

Correct Answer: B

Rationale: Step 1: Ethics refer to moral principles that govern a person's behavior. Step 2: Knowledge of what is right and wrong is essential to understanding ethics. Step 3: This knowledge guides individuals in making ethical decisions. Step 4: Choice B correctly defines ethics as the knowledge of what is right and wrong. Summary: Choice A is incorrect because ethics are not solely government rules. Choice C is incorrect as misdemeanors are legal violations, not ethical principles. Choice D is incorrect as ethics are crucial in healthcare for making moral decisions.

Correct Answer: C

Rationale: The correct answer is C because active listening involves focusing on the speaker and providing feedback to show understanding. This helps build rapport and trust with the resident. Choice A is incorrect as it shows lack of attention. Choice B is incorrect as it hinders the resident's ability to express themselves. Choice D is incorrect as it does not allow for effective communication due to lack of listening. Active listening is essential in healthcare settings to ensure residents feel heard and understood.

Correct Answer: D

Rationale: The correct answer is D because completing an incident report after any on-the-job injury is crucial for documentation, regardless of the severity or fault. This process ensures proper record-keeping, aids in identifying safety hazards, and helps in providing necessary medical care and support to the injured individual. Choices A, B, and C are incorrect because they impose unnecessary restrictions on when to report an injury, which can hinder the overall safety and well-being of the nursing assistant and others in the facility.

Correct Answer: D

Rationale: The correct answer is D: Love and affection. Psychosocial needs refer to an individual's emotional, social, and psychological well-being. Love and affection are essential for fulfilling these needs by providing emotional support, sense of belonging, and connection. Bathing (A) is a physical need related to personal hygiene, not psychosocial. Activity (B) is important for physical health but not specific to psychosocial needs. Sleep and rest (C) are necessary for physical and mental well-being, but they do not address the emotional and social aspects of psychosocial needs.
