Critical Care Nursing Questions and Answers PDF Questions
Question 1 of 9
When fluid is present in the alveoli what is the result?
Correct Answer: A
Rationale: The correct answer is A: Alveoli collapse and atelectasis occurs. When fluid is present in the alveoli, it impairs the surface tension necessary for the alveoli to remain open, leading to collapse and atelectasis. This prevents proper gas exchange, resulting in hypoxemia. Choice B is incorrect because impaired gas diffusion typically occurs with conditions affecting the alveolar-capillary membrane, not fluid in the alveoli. Choice C is incorrect as hypoventilation refers to decreased ventilation, not specifically related to fluid in the alveoli. Choice D is incorrect as fluid in the alveoli is not a direct indicator of heart failure.
Question 2 of 9
The amount of effort needed to maintain a given level of ventilation is referred to using what term?
Correct Answer: D
Rationale: The correct answer is D: Work of breathing. Work of breathing refers to the amount of effort required to maintain a specific level of ventilation. This includes the energy needed for inhalation and exhalation. Compliance (A) refers to the ease with which the lungs expand, resistance (B) is the opposition to airflow in the airways, and tidal volume (C) is the amount of air moved in and out of the lungs during normal breathing. Work of breathing encompasses the overall energy expenditure involved in the breathing process, making it the most appropriate term in this context.
Question 3 of 9
The critical care unit environment is very stressful for patients, families, and staff. What nursing action is directed at reducing environmental stress?
Correct Answer: D
Rationale: The correct answer is D: Maintaining quiet during hours of sleep. This action is essential in reducing environmental stress in the critical care unit as it promotes a restful environment for patients and allows for better sleep quality. Noise can disrupt sleep patterns and increase stress levels. Constant evaluation of patient status (A) is important but does not directly address environmental stress. Limiting visits to immediate family (B) can be beneficial in some cases but may not always reduce environmental stress. Bathing all patients during hours of sleep (C) may actually increase stress as it can be disruptive and uncomfortable for patients. Overall, maintaining a quiet environment during sleep hours is the most effective nursing action to reduce environmental stress in the critical care unit.
Question 4 of 9
What is the nurse’s priority intervention when a terminally ill patient reports severe breakthrough pain?
Correct Answer: B
Rationale: The correct answer is B: Administer a prescribed PRN opioid analgesic. This is the priority intervention because severe breakthrough pain requires immediate relief, and opioids are the most effective for managing severe pain in terminally ill patients. Warm compresses (A) may provide some comfort but do not address the underlying pain. Reassessing pain after 2 hours (C) delays necessary relief. Distraction techniques (D) are not appropriate for severe breakthrough pain as they do not directly address the pain itself. Administering the prescribed opioid analgesic promptly is crucial for providing timely and effective pain management in this situation.
Question 5 of 9
The following interventions are part of the emergency department (ED) protocol for a patient who has been admitted with multiple bee stings to the hands. Which action should the nurse take first?
Correct Answer: A
Rationale: The correct answer is A: Remove the patient's rings first. This is crucial to prevent constriction and swelling due to potential allergic reactions or inflammation from bee stings. Removing rings allows for proper circulation and prevents complications like compartment syndrome. Ice packs (B) can be applied after removing the rings to reduce swelling. Calamine lotion (C) can provide relief for itching but is not as urgent as ring removal. Diphenhydramine (D) can be given later for systemic allergic reactions but should not take precedence over removing the rings.
Question 6 of 9
The nurse is caring for a patient admitted with a traumatic brain injury following a motor vehicle crash. The patient’s Glasgow Coma Score is 3 anda binirbte.cromm/ittetset ntly withdraws when painful stimuli are introduced. The patient is ventilator dependent and occasionally takes a spontaneous breath. The primary care provider explains to the family that the patient has severe neurological impairment and it is not expected that the patient will ever recover consciousness. What concept does this situation depict?
Correct Answer: C
Rationale: The correct answer is C: A persistent vegetative state. This choice is correct because the patient exhibits minimal responsiveness, only withdrawing to painful stimuli, and lacks meaningful interaction or consciousness. A persistent vegetative state is characterized by preserved wakefulness without awareness, which aligns with the patient's condition. Choice A: An organ donor is incorrect because the patient's neurological impairment does not necessarily indicate readiness for organ donation. Choice B: Brain death is incorrect because the patient still exhibits some reflexive responses, indicating a level of brain function beyond brain death. Choice D: Terminally ill is incorrect as it does not specifically address the patient's neurological status and prognosis, which is better described by a persistent vegetative state.
Question 7 of 9
After a change-of-shift report on a ventilator weaning unit, which patient should the nurse assess first?
Correct Answer: D
Rationale: The correct answer is D - Patient who was successfully weaned and extubated 4 hours ago and now has no urine output for the last 6 hours. This patient should be assessed first because the absence of urine output for 6 hours after being extubated could indicate acute kidney injury or other serious complications that need immediate attention. Urine output is a crucial indicator of renal function and can reflect the patient's overall hemodynamic status. In contrast, the other choices do not present immediate life-threatening conditions. Choice A involves a patient in rest mode post-failed breathing trial, which does not require immediate assessment. Choice B mentions continuous PETCO2 monitoring, which is important but not as urgent as assessing a patient with no urine output. Choice C describes a patient with a ScvO2 of 69%, which may need monitoring but does not indicate an urgent priority compared to assessing a patient with no urine output after recent extubation.
Question 8 of 9
Which statement about family assessment is false?
Correct Answer: A
Rationale: The correct answer is A because assessing the structure of the family (who comprises the family) is not the last step in family assessment. The rationale is that understanding the family structure is essential at the beginning of the assessment process to identify key relationships and support systems. Assessing interaction among family members helps to understand dynamics and relationships within the family. Assessing communication is crucial to identify roles and patterns of interaction. Ongoing assessment is necessary as family dynamics can evolve throughout the illness. Therefore, A is false as family structure assessment is an important initial step, not the last step.
Question 9 of 9
A patient has just been admitted to the ICU after being in a severe auto accident and losing one of her legs. Her husband has his hand over his heart and complains of a rapid heart rate. The nurse recognizes his condition as a sign of which stage of the general adaptation syndrome to stress?
Correct Answer: A
Rationale: The correct answer is A: Alarm stage. The husband's rapid heart rate indicates the initial alarm reaction to stress, characterized by physiological arousal. This stage involves the body's fight-or-flight response to a stressor. In this scenario, the husband is experiencing the physiological effects of the stressful situation, such as the auto accident and loss of a limb. The other choices are incorrect because: B: Exhaustion stage occurs if stress continues without relief, leading to depletion of resources and increased vulnerability to illness. C: Resistance stage is the body's attempt to adapt and cope with the stressor after the initial alarm reaction. D: Adaptation stage is not a recognized stage in the general adaptation syndrome model.
