Correct Answer: C

Rationale: The correct answer is C. According to the gate control theory, meditation helps relieve pain by blocking pain impulses from coming through the gate in the central nervous system. Choice A is incorrect as meditation does not directly alter the chemical composition of pain neuroregulators. Choice B is incorrect because meditation does not stop the occurrence of pain stimuli. Choice D is incorrect as meditation does not open the gate but rather closes it to block pain impulses.

Correct Answer: B

Rationale: The priority action when a patient has a fever is to assess the patient's temperature regularly. Monitoring the temperature helps track the effectiveness of interventions and detect any worsening fever. Administering antipyretic medication (Choice A) should be done based on healthcare provider's orders after assessing the patient's condition. While providing cooling measures such as a cool compress (Choice C) can help reduce fever, assessing the temperature takes precedence. Providing blankets for comfort (Choice D) is not the priority when dealing with a fever.

Correct Answer: A

Rationale: The correct answer is to maintain the patient's oxygen saturation above 90% when caring for a patient with COPD. In COPD, impaired gas exchange leads to decreased oxygen levels in the blood. By ensuring oxygen saturation remains above 90%, healthcare providers can prevent hypoxia and its complications. Administering bronchodilators as prescribed (Choice B) is an important intervention in managing COPD symptoms, but it is not the primary goal. Improving the patient's nutritional intake (Choice C) and encouraging the patient to limit physical activity (Choice D) are also essential aspects of COPD management, but they are not the primary goal when caring for a patient with this condition.

Correct Answer: B

Rationale: During a shift change report, the most critical information to communicate is focusing on changes in the patient's condition. This helps ensure that all healthcare providers are aware of any significant developments or deterioration in the patient's health status, allowing for timely and appropriate interventions. Choices A, C, and D are not as crucial during a shift report. While a full family medical history and treatment plan are important aspects of patient care, they are not the primary focus during a shift change report. Providing updates on lab results may be important but may not be as time-sensitive or immediately impactful as changes in the patient's condition.
