Critical Care Nursing NCLEX Questions Questions
Question 1 of 5
A patient is admitted to the hospital with multiple trauma aabnirdb .ceoxmte/tensst ive blood loss. The nurse assesses vital signs to be BP 80/50 mm Hg, heart rate 135 beats/min, respirations 36 breaths/min, cardiac output (CO) of 2 L/min, systemic vas cular resistance of 3000 dynes/sec/cm5, and a hematocrit of 20%. The nurse anticip ates administration of which the following therapies or medications?
Correct Answer: C
Rationale: The correct answer is C: Dobutamine infusion. In this scenario, the patient is experiencing hypovolemic shock due to significant blood loss, resulting in low blood pressure, tachycardia, and low cardiac output. Dobutamine is a positive inotropic agent that increases cardiac contractility and output, helping to improve tissue perfusion. Blood transfusion (A) is a common intervention for hypovolemic shock, but in this case, the patient's hematocrit is low, indicating dilutional anemia rather than acute blood loss, so addressing the cardiac output is more urgent. Furosemide (B) is a diuretic that would exacerbate the hypovolemia and worsen the patient's condition. Dopamine (D) is a vasopressor that primarily increases blood pressure, but in this case, the patient's low cardiac output is the main concern, making dobutamine a more appropriate choice.
Question 2 of 5
Which of the following devices is best suited to deliver 65 % oxygen to a patient who is spontaneously breathing?
Correct Answer: D
Rationale: The Venturi mask is the best choice for delivering 65% oxygen because it allows precise oxygen concentration delivery through adjustable venturi valves. This device ensures consistent oxygen levels even during variations in patient breathing patterns. Face mask with non-rebreathing reservoir (A) delivers higher oxygen concentrations, low-flow nasal cannula (B) is not suitable for precise oxygen delivery, and simple face mask (C) may not provide the desired oxygen concentration.
Question 3 of 5
As part of the admission process, the nurse asks several questions about family relationships. The nurse bases these actions on which rationale?
Correct Answer: A
Rationale: Step-by-step rationale for why choice A is correct: 1. Involving the family in patient care is crucial for holistic care. 2. Assessing family relationships helps identify support systems and potential conflicts. 3. Understanding family dynamics aids in creating a comprehensive care plan. 4. Family involvement can enhance patient outcomes and satisfaction. Summary of incorrect choices: B. Irrelevant, as the focus is on patient-centered care, not just fulfilling an assessment tool. C. Personal curiosity is not a valid reason for assessing family relationships in healthcare. D. Conducting research on family patterns does not directly impact the immediate care of the patient.
Question 4 of 5
The patient has elevated blood urea nitrogen (BUN) and serum creatinine levels with a normal BUN/creatinine ratio. These levels most likely indicate
Correct Answer: B
Rationale: The elevated BUN and creatinine levels with a normal BUN/creatinine ratio indicate impaired kidney function. This pattern is commonly seen in acute kidney injury, such as acute tubular necrosis (ATN). In ATN, there is damage to the renal tubules leading to decreased excretion of waste products, resulting in elevated BUN and creatinine levels. The normal BUN/creatinine ratio suggests that the impairment is due to renal tubular dysfunction rather than prerenal causes like hypovolemia or postrenal causes like urinary obstruction. Increased nitrogen intake would not produce this specific pattern of results. Fluid resuscitation would likely result in dilution of BUN and creatinine levels, leading to lower values.
Question 5 of 5
Family assessment is essential in order to meet family nee ds. Which of the following must be assessed first to assist the nurse in providing family-centered care?
Correct Answer: A
Rationale: The correct answer is A because assessing the patient and family's developmental stages and needs is crucial in understanding their current situation and determining the appropriate care plan. By assessing developmental stages, the nurse can tailor interventions to meet the family's specific needs. This assessment also helps in identifying potential challenges or areas requiring support. Choice B is incorrect as it focuses solely on the physical environment and does not address the family's developmental stages and needs. Choice C is incorrect as it emphasizes identifying family members without considering the importance of understanding their developmental stages and needs in providing family-centered care. Choice D is incorrect as it concentrates on family dynamics without directly addressing the crucial aspect of assessing developmental stages and needs for effective family-centered care.
