Critical Care Nursing Practice Questions

Correct Answer: C

Rationale: The correct answer is C: High resolution multidetector CT angiogram. This diagnostic procedure is required for a definitive diagnosis of pulmonary embolism because it provides detailed imaging of the pulmonary vasculature, allowing visualization of blood clots in the pulmonary arteries. A: Arterial blood gas (ABG) analysis does not directly diagnose pulmonary embolism but may show signs of hypoxemia or respiratory alkalosis, which can be seen in some cases of pulmonary embolism. B: Chest x-ray examination may show nonspecific findings such as atelectasis or pleural effusion but cannot definitively diagnose pulmonary embolism. D: Ventilation-perfusion scanning is another imaging modality used in the diagnosis of pulmonary embolism, but it is less commonly used compared to CT angiogram due to lower sensitivity and specificity.

Correct Answer: B

Rationale: The correct answer is B: Self-directed study of best practice for the patients she cares for. This choice aligns with the Synergy Model by promoting individualized patient care based on best practices. Self-directed study allows the nurse to enhance their knowledge and skills to provide optimal care tailored to each patient's unique needs. Attending mandatory in-service programs (A) may not directly support the individualized care approach. Gathering demographic data (C) is important but not specific to the Synergy Model's focus on patient acuity and nurse competencies. Participating in a research study (D) may contribute to evidence-based practice, but it does not directly relate to the Synergy Model's emphasis on aligning nurse competencies with patient needs.

Correct Answer: C

Rationale: The correct answer is C because the patient's expressed beliefs and wishes regarding quality of life are personal factors that directly influence the ethical dilemma. This factor reflects the individual's values, beliefs, and preferences, which are essential in making ethical decisions that respect the patient's autonomy. Considering the patient's beliefs helps healthcare professionals navigate complex ethical situations by aligning the care provided with the patient's values. Choices A, B, and D do not directly relate to personal factors but rather focus on hospital policies, physiological symptoms, and the provider's perspective, respectively. Personal factors are crucial in ethical decision-making as they center on the patient's autonomy and preferences.

Correct Answer: C

Rationale: The correct answer is C: Notify the health care provider and postpone the transfer. The new onset confusion in an elderly patient in the ICU can be a sign of delirium, which is a serious condition that requires prompt evaluation and management. By notifying the healthcare provider, they can assess the patient's condition, order appropriate tests, and adjust the treatment plan as needed. Postponing the transfer allows for further observation and intervention to address the underlying cause of the confusion. Choice A (Give PRN lorazepam and cancel the transfer) is incorrect because administering lorazepam may worsen the confusion in an elderly patient and should not be done without proper evaluation. Choice B (Inform the receiving nurse and then transfer the patient) is incorrect because transferring the patient without addressing the new onset confusion can lead to potential complications and delay in appropriate management. Choice D (Obtain an order for restraints as needed and transfer the patient) is incorrect because using restraints should only be considered as a

Correct Answer: B

Rationale: The correct answer is B because implementing a medication safety program designed by pharmacists promotes a safe work environment for critical care nurses by reducing medication errors. Pharmacists are experts in medications and can provide valuable insights to improve safety. A: Celebrating with a pizza party may boost morale but does not directly address work environment factors. C: Modifying staffing ratios may improve patient care but doesn't necessarily address the overall work environment. D: Joint workshops foster collaboration but may not directly impact the work environment's safety and health.
