Question

questions 23 - 27 are derived from the following scenario: you respond to the home of a 78 - year - old man having difficulty breathing. he is sitting at the kitchen table in a classic tripod position, wearing a nasal cannula. he is cyanotic, smoking, and has his shirt unbuttoned. his respirations are 30 breaths/min and shallow, his pulse rate is 110 beats/min, and his blood pressure is 136/88 mm hg. 23. your first thought as an emt should be to: a. apply a nonrebreathing mask at 15 l/min. b. call for backup. c. assess the airway status. d. determine scene safety. 24. his brainstem senses the elevated level of ______ in the arterial blood, causing the rapid respirations. a. carbon dioxide b. oxygen c. insulin d. tobacco 25. proper management of this patient might include: a. application of a cpap device b. chest compressions c. suctioning d. epinephrine 26. which of the following is not a sign or symptom of his inadequate breathing? a. he was cyanotic. b. his blood pressure was 136/88. c. he was in a tripod position. d. his pulse rate was over 100 beats/min (tachycardia). 27. what should you do during the reassessment of this patient? a. assess vital signs every 2 minutes. b. repeat the primary assessment. c. reassess what time your shift ends. d. repeat the initial history. 28. which of the following is a question you would not typically ask during the history taking of a patient with dyspnea? a. what has the patient already done for the breathing problem? b. does the patient use a prescribed inhaler? c. does the patient have any allergies? d. what time did the patient wake up this morning?

Explanation:

1. Scene safety is the first - priority in emergency response to protect the EMT and the patient.
2. The brainstem senses elevated carbon dioxide levels in arterial blood, which stimulates rapid respirations.
3. CPAP (Continuous Positive Airway Pressure) can be used for patients with breathing difficulties to improve oxygenation.
4. Blood pressure of 136/88 is not directly a sign of inadequate breathing compared to the other options.
5. Repeating the primary assessment is important during patient reassessment to check for changes in condition.
6. The time the patient woke up in the morning is not directly relevant to the breathing problem during history - taking for dyspnea.

Answer:

1. D. determine scene safety.
2. A. carbon dioxide
3. A. application of a CPAP device
4. B. His blood pressure was 136/88.
5. B. Repeat the primary assessment.
6. D. What time did the patient wake up this morning?
