NUR 331 Exam 3 Questions And Correct Answers | Latest Update 2026/2027 | Graded A+ | 100% Pass. Reasons a patient may have an NG tube (3) 1. decompression: remove fluid and air/gas via gravity or suction 2. administer feedings, medications, and contrast 3. compress bleeding sites until endoscopy Contraindications for NG tube insertion include: (3) 1. facial trauma or recent brain surgery 2. recent nasal surgery, & known polyps, or deviated septum 3. esophageal varicies with recent or current perforation, banding, or cautery Before the placement of the tube in the patient, the nurse should check: (5) 1. The patency of the nares & presence of irritated mucosa 2. Adequate swallowing: Good for identifying those patients that will be at risk for aspiration 3. The suctioning if it is working properly bedside & other available supplies like stethoscope & tape 4. Lung & bowel sounds 5. Provider order with clarification of suction to be used like continuous or lowintermittent Confirming placement: EBP = evidence-based practice (2) 1. EBP for confirming tube placement is done by completing a x-ray (KUB) 2. Aspirating fluid to test for stomach pH Post-placement: (3) 1. secure tube to patient's gown (usually tape and safety pin) 2. watch for skin breakdown and dry mucous membranes 3. provide frequent oral care (improves patient comfort & decreases infection FiO2 fraction of inspired oxygen, an approximation of the oxygen a patient inspires Oral care frequency: (2) 1. Every 2 hours and PRN. Use suction, swabs, and chlorhexidine rinses if ordered. 2. At least once a shift, consider before or after meals. Barriers to nutrition intake for those with dysphagia (difficulty swallowing) 5 1. Diet requires a consistency modification that is not appealing, such as vegetables or meat pureed (it's gross - google it) 2. Easily fatigued since it is very labour intensive to swallow and chew effectively 3. Frustrated due to above or due to reduction in independence-cannot eat the foods they like or snack when they want 4. There are disease processes that can affect a patient's taste- ex. Covid or CVA (stroke) 5. Can be difficult to make considerations for culture or diet preferences/needs. ex. kosher or vegetarian The nurse and RT need to ensure the oxygen is delivered with the proper:(2) equipment & flow-rate Oxygen must have an ___ from the Provider order The flow meter connects to the oxygen outlet and _____ the amount delivered (L/min) regulates cyanosis cyanosis (bluish discoloration due to circulatory or oxygenation problems) metabolic acidosis responsible acid accumulation in the body Safety considerations in oxygen administration include: (3) fire, equipment failure, & pressure risk clubbing-fingers & toes elengthening of the fingertips and toes due to prolonged deficiency in oxygen right-sided heart failure a disorder that shows less effective pumping in the right side of the heart respiratory acidosis A decrease in blood pH as a result of hypoventilation (not breathing enough) and the accumulation of Co2. Nonrebreather Mask and who? mask with a valve that closes during expiration and reservoir bag that inflates with high concentrations of oxygen; 10-15 L/min (80-95%) - carbon dioxide poisoning, smoke inhalation, critically ill patients Venturi Mask delivers a predetermined and fixed oxygen concentration to the client. Early signs & symptoms of hypoxia include: (6) restlessness, confusion, anxiety, elevated blood pressure, ↑HR & RR, and dyspnea incentive spirometry (IS) a breathing exercise to improve lung function Late signs & symptoms of hypoxia include: (6) cyanosis metabolic acidosis bradycardia hypotension ↓ activity & level of consciousness Decompression Removing fluid & air/gas via gravity or suction Chronic signs & symptoms of hypoxia include: (5) clubbing (fingers & toes) edema right-sided heart failure respiratory acidosis ⪯87% (oxygen sat) ___ is an estimate of the oxygen a patient inhales. 21% is the estimated room air concentration. FiO2 Patency assessment prior to insertion Checking whether nares are open & mucosa is not irritated nasal cannula: FiO2 24-28% flow rate? humidification? 1-2 L no humidification nasal cannula: FiO2 32-36% flow rate? humidification? 3-4 L yes humidification for 4 L and up A nurse is conducting a class for a group of unit nurses about clients with a need for gastric decompression. The nurse should point out that which of the following clients requires nasogastric tube intubation for gastric decompression? A. A 6-year-old child who ingested a toxic substance B. A 60-year-old client who has a gastrointestinal hemorrhage C. A 40-year-old client who has a postoperative bowel obstruction D. A 20-year-old client who has malabsorption syndrome C. A 40-year-old client who has a postoperative bowel obstruction Rationale: A nasogastric tube is inserted for decompression in a client with postoperative bowel obstruction to eliminate gastric secretions. This will alleviate abdominal distention, nausea, & pain. Nasal Cannula a device to deliver oxygen; two prongs of device are placed into the patient nostrils The nurse should assess the client's skin for breakdown and ___ for irritation. mucous membranes Simple Face Mask and who? mask has vents; oxygen may be delivered at 5-10 L/min (40-60% FiO2) - post-anesthesia or post intubation
