Critical Care Nursing NCLEX Questions Questions
Question 1 of 9
In assessing a patient, the nurse understands that what sym ptomology is an early sign of hypoxemia?
Correct Answer: D
Rationale: Step 1: Restlessness is an early sign of hypoxemia due to the body's response to low oxygen levels. Step 2: Restlessness occurs as the body tries to increase oxygen intake. Step 3: Other choices are incorrect because clubbing and cyanosis are late signs, while hypotension is not a specific early sign of hypoxemia.
Question 2 of 9
Following an earthquake, patients are triaged by emergency medical personnel and are transported to the emergency department (ED). Which patient will the nurse need to assess first?
Correct Answer: A
Rationale: The correct answer is A: A patient with a red tag. In triage, red tags indicate patients with life-threatening injuries who require immediate attention. The nurse must assess this patient first to provide necessary interventions. Patients with blue tags are considered urgent but stable, black tags are deceased or beyond help, and yellow tags are for delayed treatment. Assessing the red-tagged patient first ensures prompt care for those in critical condition.
Question 3 of 9
The charge nurse has a Vigileo pulse contour cardiac output monitoring system available for use in the surgical intensive care unit. For which patient isa buisrbe.c oomf /ttehsits device most appropriate?
Correct Answer: B
Rationale: The correct answer is B because a mechanically ventilated patient with cardiogenic shock being treated with an intra-aortic balloon pump would benefit most from having a Vigileo pulse contour cardiac output monitoring system. This device provides continuous cardiac output monitoring and can help guide hemodynamic management in critically ill patients, especially those with hemodynamic instability like cardiogenic shock. It allows for real-time adjustments of fluid and vasoactive medications to optimize cardiac output and tissue perfusion. Choice A is incorrect because a patient with a history of aortic insufficiency and postoperative myocardial infarction may not require continuous cardiac output monitoring like the patient in choice B. Choice C is incorrect as the patient with atrial fibrillation and paroxysmal supraventricular tachycardia does not necessarily need cardiac output monitoring. Choice D is also incorrect as a mechanically ventilated patient following repair of an acute bowel obstruction may not require continuous cardiac output monitoring unless there are specific complications.
Question 4 of 9
The nurse is assessing a client who complains of weight loss, racing heart rate, and difficulty sleeping. The nurse determines the client has moist skin with fine hair, prominent eyes, lid retraction, and a staring expression. These findings are consistent with which disorder?
Correct Answer: A
Rationale: Step 1: Symptoms of weight loss, racing heart rate, and difficulty sleeping are common in hyperthyroidism. Step 2: Presence of moist skin, fine hair, prominent eyes, lid retraction, and staring expression are classic signs of Grave's disease, a type of hyperthyroidism. Step 3: Grave's disease is an autoimmune disorder where the thyroid gland is overactive, leading to excessive production of thyroid hormones. Step 4: Excess thyroid hormones increase metabolic rate, causing weight loss, racing heart rate, and insomnia. Step 5: Therefore, the findings described in the question are consistent with Grave's disease.
Question 5 of 9
When providing palliative care, the nurse must keep in mind that the family may include which of the following? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Unmarried life partners of same sex. When providing palliative care, it's crucial to recognize and respect diverse family structures. Unmarried life partners of the same sex may form a significant familial bond, requiring support and involvement in care decisions. This choice aligns with the principles of inclusivity and non-discrimination in palliative care. Incorrect choices: B: Unmarried life partners of the opposite sex - This choice is incorrect as it limits the definition of family to only opposite-sex partners, excluding same-sex couples. C: Roommates - While roommates may provide support, they do not necessarily have the same level of emotional and decision-making involvement as family members or life partners. D: Close friends - While close friends can be important sources of support, they do not necessarily have the same legal or emotional ties as a life partner.
Question 6 of 9
The nurse is caring for a mechanically ventilated patient. T he primary care providers are considering performing a tracheostomy because the patienatb iirsb .hcoamv/itensgt difficulty weaning from mechanical ventilation. Related to tracheostomy, the nurse understands which of the following?
Correct Answer: C
Rationale: The correct answer is C: Procedures performed in the operating room are associated with fewer complications. This is because performing a tracheostomy in the operating room allows for better control of the environment, equipment, and expertise of the surgical team. In this setting, the risk of complications such as bleeding, infection, and injury to surrounding structures is minimized. Choices A, B, and D are incorrect: A: Patient outcomes are better if the tracheostomy is done within a week of intubation - This statement is not universally true and depends on individual patient factors. Timing of tracheostomy should be based on the patient's clinical condition and not a set timeline. B: Percutaneous tracheostomy can be done safely at the bedside by the respiratory therapist - While percutaneous tracheostomy can be performed at the bedside, it is typically done by a trained physician or surgeon due to the potential risks and complications involved. D: The greatest risk after a per
Question 7 of 9
The nurse is caring for a critically ill patient with terminal cancer. The monitor alarms and shows ventricular tachycardia. The patient does not have a “do not resuscitate” order written on the chart. What is the appropriate nursing action?
Correct Answer: D
Rationale: The correct answer is D: Initiate CPR and call a code. In this scenario, the patient is critically ill with ventricular tachycardia, a life-threatening arrhythmia. Since there is no "do not resuscitate" order, the appropriate nursing action is to initiate CPR immediately to attempt to restore the patient's cardiac function and circulation. Calling a code will ensure that a team of healthcare providers can respond promptly with necessary interventions. Options A and B involve unnecessary delays in potentially life-saving interventions. Option C is incorrect as withholding intubation can compromise the patient's airway and oxygenation. Thus, option D is the most appropriate action to prioritize the patient's safety and well-being in this critical situation.
Question 8 of 9
A PaCO 2 of 48 mm Hg is associated with what outcome?
Correct Answer: B
Rationale: The correct answer is B: Hypoventilation. A PaCO2 of 48 mm Hg indicates an elevated level of carbon dioxide in the blood, which is typically seen in hypoventilation where the lungs are not effectively removing CO2. Hypoventilation leads to respiratory acidosis. Option A is incorrect because hyperventilation would decrease PaCO2 levels. Option C is incorrect as it does not directly relate to PaCO2 levels. Option D is incorrect as increased excretion of HCO3- would not directly affect PaCO2 levels.
Question 9 of 9
A normal glomerular filtration rate is
Correct Answer: B
Rationale: The correct answer is B (80 to 125 mL/min) because this range reflects the normal glomerular filtration rate (GFR) in adults. GFR measures the rate at which blood is filtered by the kidneys, typically around 125 mL/min. A GFR below 60 mL/min indicates kidney dysfunction, making option A incorrect. Option C (125 to 180 mL/min) is above the normal range. Option D (more than 189 mL/min) is too high and could indicate hyperfiltration, common in conditions like diabetes. Therefore, choice B is the most appropriate within the normal GFR range.
