Question 1 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 2 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 3 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.
Question 4 of 5
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 5 of 5
What does pulse oximetry measure?
Correct Answer: D
Rationale: Pulse oximetry measures oxygen saturation in the blood by analyzing the absorption of light by hemoglobin. Oxygen saturation indicates the percentage of hemoglobin molecules carrying oxygen. This is essential for assessing respiratory function and oxygen delivery to tissues. Arterial blood gases (Choice A) directly measure oxygen and carbon dioxide levels in the blood, not specifically oxygen saturation. Hemoglobin values (Choice B) provide information about the amount of hemoglobin present but not its oxygen-carrying capacity. Oxygen consumption (Choice C) is a measure of how much oxygen is used by tissues, not what pulse oximetry directly measures.
