Critical Care Nursing Practice Questions Questions
Question 1 of 5
What diagnostic procedure is required to make a definitive diagnosis of pulmonary embolism?
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.
Question 2 of 5
Daily weights are being recorded for the patient with a urine output that has been less than the intravenous and oral intake. The weight yesterday was 97.5 kg. This morning it is 99 kg. The nurse understands that this corresponds to a(n)
Correct Answer: A
Rationale: The correct answer is A: fluid retention of 1.5 liters. The weight gain from 97.5 kg to 99 kg indicates an increase in fluid retention. This difference of 1.5 kg corresponds to fluid retention of 1.5 liters, as 1 liter of water weighs approximately 1 kg. This weight gain suggests that the patient is retaining more fluid than they are excreting, leading to an increase in weight. Incorrect choices: B: fluid loss of 1.5 liters - This is incorrect because the weight increased, indicating fluid retention. C: equal intake and output due to insensible losses - This is incorrect as weight increased, showing an imbalance in intake and output. D: fluid loss of 0.5 liters - This is incorrect as the weight increased, indicating fluid retention, not loss.
Question 3 of 5
When addressing an ethical dilemma, contextual, physiolo gical, and personal factors of the situation must be considered. Which of the following is an example of a personal factor?
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.
Question 4 of 5
A hospital interviews two different candidates for a position in the ICU. Both candidates have around 10 years of experience working in the ICU. Both have excellent interpersonal skills and highly positive references. One, however, has certification in critical care nursing. Which of the following is the most compelling and accurate reason for the hospital to hire the candidate with certification?
Correct Answer: A
Rationale: The correct answer is A: The certified nurse will have more knowledge and expertise. Certification in critical care nursing indicates that the candidate has undergone specialized training and passed a standardized exam, demonstrating a higher level of knowledge and skill in critical care practices compared to a non-certified candidate. This certification ensures that the nurse has met specific competency standards in critical care, making them better equipped to handle complex situations in the ICU. Summary: - Choice B (ethical behavior) and Choice C (caring towards patients) are subjective qualities that can be present in both certified and non-certified nurses. - Choice D (collaboration with other nurses) is not directly related to certification but can be influenced by the individual's interpersonal skills. - Ultimately, the certification in critical care nursing provides concrete evidence of the candidate's advanced knowledge and expertise, making them the most compelling choice for the hospital to hire.
Question 5 of 5
While family members are visiting, a patient has a respiratory arrest and is being resuscitated. Which action by the nurse is best?
Correct Answer: A
Rationale: The correct answer is A because it respects the patient's right to privacy while also acknowledging the family's presence. By asking family members if they wish to remain in the room, the nurse allows them to make an informed decision based on their comfort level. This approach fosters open communication and shows respect for the family's emotions. Choice B is incorrect because abruptly removing family members can increase their distress and feelings of powerlessness. Choice C is incorrect as it places the burden of support solely on a staff member, potentially isolating the family from the situation. Choice D is incorrect as it assumes family members should stay without considering their preferences or emotional well-being.
