Critical Care Nursing Questions Questions
Question 1 of 9
What factors may predispose a patient to respiratory acido as bi is rb? . com/test
Correct Answer: B
Rationale: The correct answer is B: Central nervous system depression. This factor can lead to respiratory acidosis by depressing the respiratory drive, causing hypoventilation and retention of carbon dioxide. Anxiety and fear (A) may lead to hyperventilation, reducing carbon dioxide levels. Diabetic ketoacidosis (C) results in metabolic acidosis, not respiratory acidosis. Nasogastric suctioning (D) may cause respiratory alkalosis from excessive removal of carbon dioxide. Thus, central nervous system depression is the most likely factor predisposing a patient to respiratory acidosis.
Question 2 of 9
In calculating the glomerular filtration rate (GFR) results for women, the creatinine clearance is usually:
Correct Answer: C
Rationale: The correct answer is C: multiplied by 0.85. This is because women typically have lower muscle mass compared to men, resulting in lower creatinine production. Therefore, to adjust for this difference, the creatinine clearance for women is multiplied by 0.85. This correction factor helps to more accurately estimate the GFR in women. Choices A and B are incorrect because the creatinine clearance for women is not the same as or greater than that for men due to the physiological differences in muscle mass. Choice D is also incorrect as multiplying by 1.15 would overestimate the GFR in women.
Question 3 of 9
What factors are common to both pain and anxiety? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Cyclical exacerbation of one another. Pain and anxiety can intensify each other in a cyclical manner. Pain can trigger anxiety, making the pain feel worse, and anxiety can heighten pain perception. This relationship is well-documented in research and clinical practice. Choice B is incorrect because although both pain and anxiety benefit from thorough nursing assessment, it is not a factor common to both conditions. Choice C is incorrect as both pain and anxiety can be influenced by real and perceived phenomena, not solely real phenomena. Choice D is incorrect because while previous experiences can impact pain and anxiety perception, it is not a factor common to both conditions.
Question 4 of 9
Which therapeutic interventions may be withdrawn or withabhirebl.dco mfr/otemst the terminally ill client? (Select all that apply.)
Correct Answer: B
Rationale: The correct answer is B: Dialysis. In the context of terminally ill clients, withdrawing dialysis is appropriate as it can be burdensome without providing significant benefit towards the end of life. Dialysis does not cure terminal conditions and can prolong suffering unnecessarily. Antibiotics (A) may be necessary for managing infections in terminally ill clients. Nutrition (C) is important for comfort and quality of life. Pain medications (D) are essential for managing pain and should not be withdrawn unless no longer beneficial or requested by the patient.
Question 5 of 9
A nurse has been working as a staff nurse in the surgical inabteirbn.scoivme/t ecsat re unit for 2 years and is interested in certification. Which credential would be most applicable for her to seek?
Correct Answer: C
Rationale: The correct answer is C: CCRN. The nurse works in a surgical unit, making CCRN (Critical Care Registered Nurse) the most applicable credential as it focuses on critical care nursing, which is relevant to the nurse's current practice. ACNPC (Acute Care Nurse Practitioner Certification) and PCCN (Progressive Care Certified Nurse) are not suitable as they are more focused on advanced practice or progressive care respectively, not directly related to surgical units. CCNS (Clinical Nurse Specialist Certification) is not the best choice as it is more geared towards advanced practice roles in specific clinical specialties, not general staff nursing.
Question 6 of 9
A nurse is on a committee that is trying to reduce the occurrence of hospital-acquired infections in the ICU. Her role is to conduct research to find which interventions have been shown to be most effective in reducing these infections. She consults many different sources and finds conflicting information. Which of the following sources should she consider the most authoritative?
Correct Answer: B
Rationale: The correct answer is B: A meta-analysis of randomized controlled trials in the American Journal of Nursing. 1. Meta-analyses provide a comprehensive overview of multiple studies, increasing the reliability of the findings. 2. Randomized controlled trials are considered the gold standard in research design for assessing intervention effectiveness. 3. The American Journal of Nursing is a reputable source in the field of nursing, ensuring the credibility of the study. 4. By synthesizing data from various trials, the meta-analysis can offer a more robust and generalizable conclusion compared to a single trial or qualitative studies. Incorrect choices: A: AACN expert panel report - Expert opinions may vary and lack the empirical evidence provided by research studies. C: A systematic review of qualitative studies in the Journal of Advanced Nursing - Qualitative studies may provide valuable insights but may not offer concrete evidence on intervention effectiveness like quantitative studies. D: A single randomized controlled trial in the American Journal of Critical Care - Single trials may not capture the full picture and
Question 7 of 9
An elderly patient is admitted to the ICU with stage IV lung cancer, diabetes mellitus, and congestive heart failure. The health care team assembled to care for her is large and diverse, including an oncologist, a pulmonologist, an endocrinologist, a cardiologist, and others. The patient is not expected to survive more than a few weeks, and her husband is overwhelmed with stress and grief. Which nurse competency or competencies are most needed in this situation? Select all that apply.
Correct Answer: B
Rationale: The correct answer is B: Caring practices. In this situation, the patient and her husband are dealing with complex medical conditions and emotional distress. Caring practices involve providing compassionate, empathetic, and supportive care to the patient and her family members during this difficult time. The nurse needs to show sensitivity, understanding, and emotional support to help them cope with their situation. Clinical judgment (A) is important but not the primary focus in this scenario. Collaboration (C) is essential in the interdisciplinary team, but caring practices take precedence in addressing the emotional needs. Response to diversity (D) is also important, but in this case, the focus is more on providing compassionate care rather than addressing cultural or social diversity issues.
Question 8 of 9
To maintain proper cuff pressure of an endotracheal tube (ET) when the patient is on mechanical ventilation, the nurse should:
Correct Answer: D
Rationale: The correct answer is D because inflating the cuff until a slight leak is heard only at peak inflation ensures it is adequately sealed but not overinflated, preventing complications like tracheal injury or pressure necrosis. Choice A lacks specificity and can lead to overinflation. Choice B may result in overinflation as the firmness of the balloon is subjective. Choice C relies on a specific pressure reading, which may vary based on factors like tube size and patient anatomy, potentially leading to under- or overinflation.
Question 9 of 9
The critical care environment is often stressful to a criticalalbyir bil.clo pma/tteiset nt. Identify stressors that are commonly stressful for the critically ill patient. (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Alarms that sound from various devices. In the critical care environment, alarms often indicate changes in the patient's condition, causing stress. Bright fluorescent lighting (B) may be bothersome but not directly related to patient stress. Lack of day-night cues (C) may disrupt sleep patterns but is not a direct stressor. Sounds from the mechanical ventilator (D) are essential for patient care and not inherently stressful.
