Correct Answer: C

Rationale: The correct answer is C: Respiratory acidosis may occur if the patient continues at these ventilator settings. Respiratory acidosis happens when the lungs cannot remove enough of the carbon dioxide (CO2) produced by the body. In this case, the low respiratory rate of 14 breaths/min may not be sufficient to adequately remove CO2, leading to its accumulation in the blood. This results in a decrease in blood pH, causing respiratory acidosis. Summary of other choices: A: Metabolic acidosis - Not the correct answer as the ventilator settings are more likely to affect the respiratory system rather than the metabolic system. B: Metabolic alkalosis - Not the correct answer as the ventilator settings are not related to causing an increase in blood pH, which is characteristic of metabolic alkalosis. D: Respiratory alkalosis - Not the correct answer as the low respiratory rate would not lead to excessive elimination of CO2, causing alkalosis.

Correct Answer: B

Rationale: The correct answer is B because developing a list of questions for the physician shows active engagement in their healthcare, seeking information, and taking control of their situation, which are characteristics of resiliency. This behavior indicates the patient's willingness to understand and cope with their health condition. Choices A, C, and D are incorrect as they demonstrate maladaptive coping mechanisms such as dysfunctional grieving, denial, and blame assignment, which are not indicative of resiliency. Resiliency involves adaptability, problem-solving, and seeking support, which are better exemplified by choice B.

Correct Answer: D

Rationale: The correct answer is D: Facilitation of learning. In this scenario, the nurse needs to effectively educate the patient on managing her diet, insulin injections, and handling emergencies. Facilitation of learning involves assessing the patient's learning needs, providing relevant information, demonstrating skills, and evaluating understanding. This competency is crucial for promoting patient education and empowerment in managing their condition. A: Clinical judgment involves making decisions based on assessment data, which is important but not the primary focus in this situation. B: Advocacy and moral agency involve standing up for patients' rights and values, which is important but not as directly relevant to the patient's education needs. C: Caring practices involve showing empathy and compassion, which are essential but not the main competency required for educational purposes in this case.

Correct Answer: C

Rationale: The correct interpretation is uncompensated respiratory acidosis (Choice C) based on the values. Step 1: Evaluate pH - pH is <7.35, indicating acidosis. Step 2: Determine PaCO2 - PaCO2 is >45 mmHg, indicating respiratory cause. Step 3: Check HCO3- - HCO3- is within normal range, indicating uncompensated state. Choices A, B, and D are incorrect because they do not align with the given blood gas values.

Correct Answer: C

Rationale: The correct answer is C: Brain death has occurred if there is no breathing and certain reflexes are absent. Brain death is defined as the irreversible cessation of all functions of the entire brain, including the brainstem. The absence of breathing and certain reflexes, such as no response to painful stimuli or no pupillary response to light, are key indicators of brain death. This definition is crucial for determining eligibility for organ donation. Incorrect choices: A: Brain death occurs if a person is flaccid and unresponsive. Flaccidity and unresponsiveness are not specific criteria for diagnosing brain death. B: If CPR is ineffective in restoring a heartbeat, the brain cannot function. The absence of a heartbeat alone does not indicate brain death. D: If respiratory efforts cease and no apical pulse is audible, brain death is present. Respiratory cessation and the absence of pulse are not definitive signs of brain death.
