NURS 325 Fundamentals Exam 3 2022

NURS 325 Fundamentals Exam 3 2022. This is an all-inclusive guide to NURS 325 to score A+. A nurse explains the function of the alveoli to a patient with respiratory problems. Which information about the alveoli’s function will the nurse share with the patient? Selected Answer: a. Carries out gas exchange Answers: a. Carries out gas exchange b. Regulates tidal volume c. Stores oxygen d. Produces hemoglobin Response Feedback: The alveolus is a capillary membrane that allows gas exchange of oxygen and carbon dioxide during respiration. The alveoli do not store oxygen, regulate tidal volume, or produce hemoglobin.  Question 2 1.42 out of 1.42 points A home care nurse is inspecting a patient’s house for safety issues. Which findings will cause the nurse to address the safety problems? (Select all that apply.) Selected Answers: a. Stairway faintly lit b. Scatter rugs in the kitchen c. Absence of smoke alarms Answers: a. Stairway faintly lit b. Scatter rugs in the kitchen c. Absence of smoke alarms d. Level thresholds between bathroom and bedroom e. Bathtub with grab bars f. Low-pile carpeting in the living room Response Feedback: Assess the patient’s home for common hazards, including the following: (1) loose area rugs and runner placed over carpeting, (2) poor lighting in stairways, and (3) absence of smoke alarms. Because of reduced depth perception, patients can trip on throw rugs, runners, or the edge of stairs. A bathtub with grab bars is safe and does not need to be addressed. Teach patients and family members to keep all flooring in good repair, and advise them to use low-pile carpeting. Thresholds between rooms need to be level with the floor.  Question 3 1.42 out of 1.42 points The nurse suspects the patient has increased afterload. Which piece of equipment should the nurse obtain to determine the presence of this condition? Selected Answer: a. Blood pressure cuf Answers: a. Blood pressure cuf b. Oxygen cannula c. Pulse oximeter d. Yankauer suction tip catheter Response Feedback: A blood pressure cuf is needed. The diastolic aortic pressure is a good clinical measure of afterload. Afterload is the resistance to left ventricular ejection. In hypertension the afterload increases, making cardiac workload also increase. A pulse oximeter is used to monitor the level of arterial oxygen saturation; it will not help determine increased afterload. While an oxygen cannula may be needed to help decrease the efects of increased afterload, it will not help determine the presence of afterload. A Yankauer suction tip catheter is used to suction the oral cavity.  Question 4 1.42 out of 1.42 points The nurse enters the patient’s room and notices a small fire in the headlight above the patient’s bed. In which order will the nurse perform the steps, beginning with the first one? 1. Pull the alarm. 2. Remove the patient. 3. Use the fire extinguisher. 4. Close doors and windows.
