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
The patient is admitted with acute kidney injury from a postrenal cause. Acceptable treatments for that diagnosis include: (Select all that apply.)
Correct Answer: A
Rationale: Step-by-step rationale: 1. Bladder catheterization helps relieve urinary obstruction, a common postrenal cause of acute kidney injury. 2. By draining urine from the bladder, it prevents further damage to the kidneys. 3. This intervention addresses the underlying cause of the kidney injury, leading to improvement. Summary: - Choice A is correct as it directly addresses the postrenal cause by relieving urinary obstruction. - Choices B, C, and D are incorrect as they do not target the specific postrenal cause of acute kidney injury.
Question 3 of 5
Which of the following statements about comfort care is aacbcirubr.caotme/?te st
Correct Answer: C
Rationale: Step 1: Comfort care is focused on providing relief from suffering and improving quality of life. Step 2: Patient-centered care emphasizes the individual's preferences and values. Step 3: Patient autonomy is a fundamental principle in healthcare decision-making. Step 4: Patients have the right to determine what constitutes comfort care for themselves. Step 5: Therefore, statement C is correct as it aligns with the patient's autonomy and individualized care approach. Summary: - Choice A is incorrect because legal distinctions between withholding and withdrawing treatment may vary. - Choice B is incorrect as it focuses on evaluating procedures rather than the patient's preferences. - Choice D is incorrect as withdrawing life-sustaining treatments is not universally considered euthanasia.
Question 4 of 5
Which patient should the nurse refer for hospice care?
Correct Answer: C
Rationale: The correct answer is C because the patient with AIDS-related dementia requires palliative care and pain management, which are key components of hospice care. This patient is likely in the terminal stage of their illness and would benefit from the comprehensive support provided by hospice services. Choice A is incorrect because the patient's children's inability to discuss dying issues does not necessarily indicate a need for hospice care. Choice B is incorrect as chronic severe pain due to spinal arthritis is not a sole criterion for hospice referral. Choice D is incorrect as advanced liver failure alone does not automatically qualify a patient for hospice care.
Question 5 of 5
The nurse identifies a client's needs and formulates the nursing problem of, 'Imbalanced nutrition: less than body requirements, related to mental impairment and decreased intake, as evidenced by increasing confusion and weight loss of more than 30 pounds over the last 6 months.' Which short-term goal is best for this client?
Correct Answer: B
Rationale: The correct short-term goal for the client with imbalanced nutrition is choice B: Eat 50% of six small meals each day by the end of one week. This goal is specific, measurable, achievable, relevant, and time-bound (SMART). By setting a goal for the client to eat a specific amount of meals within a defined timeframe, it allows for objective monitoring of progress. This goal also addresses the client's decreased intake and aims to improve their nutritional status gradually. Choice A is incorrect as verbalizing understanding does not directly address the client's nutritional needs. Choice C is not appropriate as it does not promote independence in meal consumption. Choice D is not the best short-term goal as it focuses on the outcome of weight gain rather than the process of increasing food intake. Overall, choice B is the most appropriate short-term goal as it targets the client's specific nutritional needs and provides a clear direction for intervention.
