Acute Respiratory Care Nursing Questions Questions
Question 1 of 5
The nurse is caring for a client receiving oxygen therapy via a Venturi mask. Which assessment finding indicates the need for adjustment of the oxygen flow rate?
Correct Answer: C
Rationale: The client reporting nasal dryness and discomfort indicates inadequate humidification of the oxygen. The nurse should assess and adjust the oxygen flow rate or consider providing additional humidification to alleviate the client's discomfort and ensure effective oxygen therapy.
Question 2 of 5
A nurse cares for a client who is one hour post vaginal delivery. Which findings are an early sign of postpartum hemorrhage?
Correct Answer: C
Rationale: An increasing heart rate is often one of the first indicators of inadequate blood volume and the earliest sign of shock. The heart rate increases to keep cardiac output and mean arterial pressure at normal levels. A uterus that is enlarging may indicate clots are accumulating in the uterus and lead to uterine atony and postpartum hemorrhage.
Question 3 of 5
A nurse provides teaching to a client who is scheduled for a colonoscopy. Which statements should be included? Select one that doesn't apply.
Correct Answer: B
Rationale: 1. The client should consume a clear liquid diet the day before the colonoscopy and avoid red, orange, or purple (grape) beverages. 3. The client should avoid certain medications such as aspirin, anticoagulants and antiplatelet medications for several days prior to the procedure or as instructed by the provider. 4. Oral solutions can be chilled to help improve taste. Watery diarrhea usually begins an hour after administration. 5. Instruct the client to arrange for transportation home from the procedure. The client should be instructed not to drive or operate equipment for 12 to 18 hours after the colonoscopy.
Question 4 of 5
A nurse discovers a small paper fire in a trash can in a client's bathroom. The client has been taken to safety and the alarm has been activated. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: The document incorrectly lists Class C (B) for a paper fire which requires a Class A extinguisher (water or dry chemical). Opening windows (A) can spread smoke and fire. Removing electrical equipment (C) is unnecessary for a paper fire and delays response. Wet towels (D) are for containment not extinguishing. The rationale corrects the error: a Class A extinguisher is needed for paper fires but based on the document B is listed as correct.
Question 5 of 5
When planning care,for which client should the nurse include close observation for a decreased or absent cough reflex?
Correct Answer: B
Rationale: The cough reflex relies on vagus nerve (cranial nerve X) conduction to the medulla. Impairment of vagus nerve function (B) such as from spinal cord injury or CNS depression can decrease or eliminate the cough reflex increasing risks of aspiration and respiratory infections requiring close monitoring. Nasal fractures (A) and sinus infections (C) do not typically affect the cough reflex. Reduced respiratory membrane conduction (D) impacts gas exchange
