Critical Care Nursing Questions Questions
Question 1 of 9
A triage nurse in a busy emergency department (ED) assesses a patient who complains of 7/10 abdominal pain and states, 'I had a temperature of 103.9°F (39.9°C) at home.' The nurse’s first action should be to:
Correct Answer: A
Rationale: The correct answer is A: Assess the patient's current vital signs. The nurse's first action should be to gather objective data to assess the patient's condition and determine the urgency of the situation. Vital signs, including temperature, heart rate, blood pressure, and respiratory rate, provide crucial information for the initial assessment. This will help the nurse identify any signs of sepsis, shock, or other serious conditions that require immediate intervention. The other choices are incorrect because: B: Giving acetaminophen without assessing the patient's vital signs and determining the cause of the symptoms could mask important clinical information and delay appropriate treatment. C: While obtaining a urine sample may be necessary later to rule out a urinary tract infection, it is not the most immediate priority in this case. D: Delaying the patient's assessment and care based on estimated wait times is not appropriate when the patient presents with potentially serious symptoms. Immediate evaluation is required in this scenario.
Question 2 of 9
The nurse assesses a patient who is admitted for an overdo se of sedatives. The nurse expects to find which acid-base alteration?
Correct Answer: B
Rationale: The correct answer is B: Hypoventilation and respiratory acidosis. When a patient overdoses on sedatives, it can lead to respiratory depression causing hypoventilation. Hypoventilation results in retention of CO2, leading to respiratory acidosis. This is because the body is not effectively exhaling CO2, causing an increase in carbonic acid levels and a decrease in blood pH. The other choices are incorrect because hyperventilation would lead to respiratory alkalosis (Choice A), hypoventilation does not cause respiratory alkalosis (Choice C), and normal oxygen levels do not indicate the acid-base imbalance caused by sedative overdose (Choice D).
Question 3 of 9
The family of a critically ill patient has asked to discuss organ donation with the patient’s nurse. When preparing to answer the family’s questions, th e nurse understands which concern(s) most often influence a family’s decision to donate? (Select all that apply.)
Correct Answer: A
Rationale: Rationale for Correct Answer A: Donor disfigurement influences on funeral care. Families often consider the impact of organ donation on the appearance of their loved one during funeral arrangements. This concern can significantly influence their decision to donate. Incorrect Answers: B: Fear of inferior medical care provided to donor. This is not a common concern as medical care for donors is typically of high quality. C: Age and location of all possible organ recipients. While important, this is not a primary concern for families when deciding on organ donation. D: Concern that donated organs will not be used. Families are generally more concerned about the impact on their loved one's appearance post-donation rather than the utilization of organs.
Question 4 of 9
A 100-kg patient gets hemodialysis 3 days a week. In planning the care for this patient, the nurse recommends
Correct Answer: A
Rationale: The correct answer is A: a diet of 2500 to 3500 kcal per day. During hemodialysis, the patient loses nutrients and energy, so a high-calorie diet is necessary to maintain proper nutrition and energy levels. 2500-3500 kcal/day is a suitable range for a 100-kg patient. Choice B is incorrect because protein intake should be adequate to prevent malnutrition in hemodialysis patients, typically 1.2g/kg body weight/day. Choice C is incorrect as potassium intake should be restricted in hemodialysis patients due to impaired kidney function. Choice D is incorrect because fluid intake should be individualized based on the patient's fluid status and should not be limited to less than 500 mL per day.
Question 5 of 9
During the primary assessment of a victim of a motor vehicle collision, the nurse determines that the patient is breathing and has an unobstructed airway. Which action should the nurse take next?
Correct Answer: B
Rationale: Rationale: The correct action is to observe the patient's respiratory effort next. This step ensures that the patient's breathing remains stable and adequate. If respiratory effort is compromised, immediate intervention is required. Checking for bilateral pulses (A) is important but comes after ensuring respiratory status. Checking level of consciousness (C) is also crucial but not as immediate as monitoring breathing. Examining for external bleeding (D) is important but not the priority when airway and breathing are already determined to be clear.
Question 6 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 7 of 9
The nurse caring for a critically ill patient implements several components of care. What component is an example of the use of evidence-based practice?
Correct Answer: B
Rationale: The correct answer is B because applying an insulin sliding scale method based on research is an example of evidence-based practice. This method is derived from scientific evidence and research studies, ensuring the best outcomes for the patient. The other choices lack the same level of evidence-based rationale: A is based on a protocol, which may not be evidence-based; C is a standard safety practice, not necessarily evidence-based; D is a decision based on hospital policy or practicality, not specifically evidence-based.
Question 8 of 9
The nurse is a member of a committee to design a critical care unit in a new building. Which design trend would best be implemented to facilitate famil y-centered care?
Correct Answer: A
Rationale: Correct Answer: A Rationale: 1. Family-centered care promotes involvement of family members in patient care. 2. A sleeper sofa in the patient's room allows family members to stay overnight, enhancing support for the patient. 3. Storage for personal belongings ensures families can have essentials close by, increasing comfort and convenience. 4. These design elements facilitate family presence, communication, and participation in care, aligning with family-centered care principles. Summary of Incorrect Choices: B. Having a diagnostic suite nearby is convenient but not directly related to family-centered care principles. C. A waiting room with amenities is beneficial but does not directly involve families in patient care. D. Access to a garden for meditation is helpful for relaxation but does not emphasize family involvement in care.
Question 9 of 9
The patient undergoes a cardiac catheterization that requires the use of contrast dyes during the procedure. To detect signs of contrast-induced kidney injury, the nurse should
Correct Answer: B
Rationale: The correct answer is B because evaluating the patient's serum creatinine for up to 72 hours after the procedure is crucial in detecting contrast-induced kidney injury. An increase in serum creatinine levels indicates impaired kidney function due to the contrast dye. This monitoring allows for early detection and intervention to prevent further kidney damage. Choice A is incorrect because a decrease in urine output is a late sign of kidney injury and may not be present in the early stages. Choice C is incorrect as a renal ultrasound is not typically used to detect contrast-induced kidney injury. Choice D is incorrect as postvoid residual volume assessment is not specific to detecting intrarenal injury related to contrast dye use.
