Critical Care Nursing Questions and Answers PDF Questions
Question 1 of 5
What is the primary mode of action of a neuromuscular bl ocking agent?
Correct Answer: C
Rationale: The correct answer is C: Paralysis. Neuromuscular blocking agents work by blocking the transmission of nerve impulses at the neuromuscular junction, leading to muscle paralysis. This paralysis helps facilitate intubation, surgical procedures, and mechanical ventilation. A: Analgesia - Neuromuscular blocking agents do not provide pain relief; they primarily induce muscle paralysis without affecting pain sensation. B: Anticonvulsant - Neuromuscular blocking agents do not prevent or treat seizures; their mechanism of action is not related to controlling convulsions. D: Sedation - Neuromuscular blocking agents do not induce sedation; they specifically target the neuromuscular junction to cause muscle paralysis.
Question 2 of 5
The nurse is concerned about the risk of alcohol withdraw al syndrome in a 45-year-old postoperative patient. Which statement indicates an unders tanding of management of this patient?
Correct Answer: D
Rationale: The correct answer is D because initiating the alcohol withdrawal protocol shows an understanding of managing a patient at risk for alcohol withdrawal syndrome. This protocol involves carefully monitoring the patient's symptoms, providing appropriate medications, and ensuring a safe environment. Option A is incorrect as it downplays the seriousness of alcohol withdrawal. Option B is incorrect as there are assessment tools available for identifying alcohol withdrawal. Option C is incorrect as pain management should be tailored to the individual's needs, not necessarily lessened due to alcohol withdrawal risk.
Question 3 of 5
What factors associated with the critical care unit can pred ispose the client to increased pain and anxiety? (Select all that apply.)
Correct Answer: A
Rationale: The presence of an endotracheal tube can predispose the client to increased pain and anxiety due to discomfort, difficulty breathing, and potential for aspiration. The tube insertion process itself can be painful and traumatic. Frequent vital sign assessment, monitor alarms, and room temperature are not directly associated with increased pain and anxiety from the endotracheal tube.
Question 4 of 5
A patient requires neuromuscular blockade (NMB) as part of treatment of refractive increased intracranial pressure. The nursing care for this patient includes which interventions? (Select all that apply.)
Correct Answer: C
Rationale: The correct answer is C: Ensuring that deep vein thrombosis prophylaxis is initiated. When a patient requires neuromuscular blockade for increased intracranial pressure, they are likely immobile, which increases the risk of deep vein thrombosis (DVT). Initiating DVT prophylaxis, such as compression stockings or anticoagulant therapy, helps prevent blood clot formation. Choice A is incorrect because sedatives can mask signs of neurologic deterioration in this patient population. Choice B is incorrect as it promotes activities that may increase intracranial pressure and could be harmful. Choice D, while important for overall patient care, is not directly related to the specific nursing interventions required for a patient receiving neuromuscular blockade for increased intracranial pressure.
Question 5 of 5
A 65-year-old patient admitted to the progressive care unit with a diagnosis of community-acquired pneumonia, has a history of chronic obstructive pulmonary disease and diabetes. A set of arterial blood gases obtained on admissiaobnir bw.coitmh/oteustt supplemental oxygen shows pH 7.35; PaCO 55 mm Hg; bicarbonate 30 mEq/L ; PaO 65 mm Hg. These blood 2 2 gases reflect what condition?
Correct Answer: B
Rationale: The correct answer is B: Hypoxemia and compensated respiratory acidosis. The patient's pH is within normal range (7.35), indicating compensation. The elevated PaCO2 (55 mm Hg) indicates respiratory acidosis due to inadequate ventilation, likely from COPD. The low PaO2 (65 mm Hg) indicates hypoxemia, common in pneumonia. The normal bicarbonate level (30 mEq/L) suggests metabolic compensation for respiratory acidosis. Choice A is incorrect as there is no metabolic alkalosis present. Choice C is incorrect as the patient has hypoxemia. Choice D is incorrect as the patient is showing compensated respiratory acidosis, not uncompensated.
