NBRC / TMC / RRT Exam 2025 Prep Test Bank with 350 Test Questions and Correct Detailed Answers with Rationales Test Bank Latest An orally intubated patient is breathing spontaneously through an 8.0 mm ET tube. In the ambient air, humidity indicates only 22 mg per liter of air. Based on this, what humidity deficit will the respiratory therapist have to make up to completely meet the humidity needs of the patient? A. 44 mg/L of gas B. 22 mg/L of gas C. 12 mg/L of gas D. 100 mg/L of gas - Correct Answer :The correct answer is : B A patient receiving oxygen via a pulse-dose oxygen system complains of difficulty breathing and indicates she believes the cannula is not working properly. The respiratory therapist should A. troubleshoot the pulse-dose regulator B. instruct the patient call the manufacturer C. instruct the patient to switch to her oxygen concentrator with a regular nasal cannula D. replace the oxygen tank – Correct Answer :The correct answer is : C One hour after performing quality control on a blood gas analyzer, a respiratory therapist obtains arterial blood from a patient breathing supplemental oxygen at 2 L/min by nasal cannula. The following blood gas results are available: NBRC / TMC / RRT Exam 2025 A+ TEST BANK 2 pH 7.41 PaCO2 39 torr PaO2 190 torr HCO3- 25 mEq/L BE -1 mEq/L The respiratory therapist should A. replace the Sanz electrode, repeat the analysis B. perform a two-point calibration and repeat the analysis C. recommend discontinuing supplemental oxygen based on these results D. report the blood gas results – Correct Answer :The correct answer is : B Which of the following patients does NOT require additional help to make up the humidity deficit during ventilation? A. A patient with a tracheostomy B. A spontaneously breathing patient who is intubated nasally C. A patient who is orally intubated with an endotracheal tube D. A patient using an oral pharyngeal airway – Correct Answer :The correct answer is : D The respiratory therapist analyzes the blood from a patient rescued from an area lake. The patient had been ice fishing when the ice broke and he plunged into the water. Rescuers indicate it took about 5 minutes to get the patient out. The patient remains hypothermic. Blood gas analysis reveals pH 7.50 PaCO2 28 torr PaO2 65 torr The respiratory therapist should suspect erroneous readings in which of the following? NBRC / TMC / RRT Exam 2025 A+ TEST BANK 3 A. PaCO2 would be erroneously high B. PaO2 would read erroneously low C. pH would be erroneously low D. both PaO2 and PaCO2 would read erroneously high – Correct Answer :The correct answer is : B Which of the following laboratory examinations would be helpful in further assessing a patient with diabetic ketoacidosis? A. creatinine B. glucose level C. respiratory quotient D. urine specific gravity – Correct Answer :The correct answer is : B A patient is receiving IPPB therapy by mouthpiece following abdominal surgery and is still somewhat lethargic from the anesthesia. During the treatment, the respiratory therapist notes the IPPB machine frequently fails to cycle into expiration. Which of the following should the therapist do to correct the problem? A. Replace the mouthpiece with an inflatable mask B. Increase the flow C. Lower the pressure D. Increase the sensitivity - Correct Answer :The correct answer is : A A radiological report is placed in the medical record that describes the results of a chest radiograph. The report indicates plate-like infiltrates bilaterally. This finding is consistent with A. pulmonary edema B. pleural effusion C. atelectasis An orally intubated patient is breathing spontaneously through an 8.0 mm ET tube.
