Critical Care Nursing Exam Questions

Correct Answer: A

Rationale: The correct answer is A. Infants typically have higher resting heart rates than adults, so a pulse rate of 89 beats/minute for an infant may indicate bradycardia. Digoxin can further lower the heart rate, leading to potential adverse effects like arrhythmias. Therefore, withholding the medication and contacting the healthcare provider is crucial to ensure the safety of the infant. Choice B is incorrect because administering digoxin without addressing the elevated pulse rate can be dangerous. Choice C is incorrect as assessing respiratory rate does not address the immediate concern of the elevated pulse rate. Choice D is also incorrect as waiting and giving half of the dosage may further exacerbate the situation.

Correct Answer: A

Rationale: The correct answer is A because it acknowledges the family member's feelings while offering support and resources for managing the situation gradually. By providing resources, the nurse empowers the family member to learn how to handle things independently over time. This approach promotes self-reliance and resilience. Choice B focuses on time rather than active coping strategies, which may not address the family member's immediate needs. Choice C suggests shifting responsibilities to another family member without considering the emotional impact. Choice D jumps to the conclusion of needing professional counseling without exploring other potential solutions or support systems.

Correct Answer: C

Rationale: Step-by-step rationale for why choice C is correct: 1. Intrapulmonary shunting refers to blood bypassing the normal oxygenation process in the lungs. 2. Choice C describes blood being shunted from the right side of the heart (deoxygenated blood) to the left side without oxygenation, leading to systemic circulation without oxygenation. 3. Choices A, B, and D do not accurately describe intrapulmonary shunting as they focus on other concepts like alveolar perfusion, heart failure, and unilateral lung blood supply, respectively.

Correct Answer: A

Rationale: Step 1: Asking the patient whether he or she wants to get out of bed allows the patient to make a decision regarding their immediate environment, promoting autonomy and control. Step 2: This intervention respects the patient's preferences and fosters a sense of dignity and empowerment, reducing stress. Step 3: Best practice principles in nursing emphasize patient-centered care and promoting patient autonomy. Summary: Choice A is correct as it directly involves the patient in decision-making, enhancing their sense of control. Choices B, C, and D do not provide the same level of autonomy and control to the patient, making them less effective in reducing stress and promoting patient well-being.

Correct Answer: D

Rationale: The correct answer is D: To validate a nurse�s knowledge of critical care nursing. Certification in critical care nursing validates a nurse's expertise and knowledge in this specialized area of nursing. It demonstrates that the nurse has met certain standards and competencies in critical care practice. This certification ensures that the nurse is well-equipped to provide high-quality care to critically ill patients. A: To assure the consumer that critical nurses will not make a mistake - This choice is incorrect because certification does not guarantee that nurses will not make mistakes. It focuses on validating knowledge and skills rather than infallibility. B: To help prepare the critical care nurse for graduate school - This choice is incorrect as certification is more focused on practice readiness rather than academic preparation. C: To assist in promoting magnet status for a facility - This choice is incorrect as magnet status relates more to the overall excellence and quality of nursing care in a facility, not individual certification.
