Ch. 87 Oxygen Therapy & Respiratory Disorders IN BASIC NURSING

OXYGEN THERAPY AND RESPIRATORY DISORDERS - CHAPTER 87:

What is the most important safety issue related to oxygen administration, that the nurse should consider?

• Oxygen allows common flammable materials to burn faster and hotter.

• Oxygen should be given to all clients postoperatively to prevent nosocomial infections.

• Oxygen can increase the heart's work of pumping blood.

• Decreased oxygen concentration weakens the stimulus to breathe.

The nurse is explaining to a client diagnosed with cystic fibrosis the goals of the oxygen therapy being prescribed. Which is a therapeutic effect of oxygen administration?

• It reverses high and low oxygen concentrations in the blood.

• It increases the work of the respiratory system, allowing it to work more efficiently.

• It decreases the heart's work in pumping blood and eases the heart's load.

• It affects ventilatory drive control mechanisms and increases the stimulus to breathe.

The nurse administering oxygen to clients with respiratory disorders is careful to monitor concentrations to prevent oxygen toxicity. How does this adverse reaction manifest itself?

• Changes in heart rate

• Changes in level of consciousness

• Changes in blood pressure

• Changes in lung tissue

A nurse is caring for a newborn receiving 100% oxygen for resuscitation through an oxygen mask. What potential complication is of most concern for in this client?

• Thermal burns

• Decreased pulse

• Dry and irritated nares

• Vision difficulties

A client after cardiac arrest is receiving oxygen therapy via a mask. What unit should the nurse use to document the amount of oxygen delivered?

• Liters per minute

• Milliliters per minute

• Pounds per square inch

• Liters per square inch

The nurse is using a pulse oximeter to determine the percentage of oxygen saturation in a client's blood. Which pulse oximetry reading indicates that the client needs immediate supplemental oxygen?

• 85%

• 90%

• 95%

• 100%

A nurse is caring for a client receiving oxygen from a large oxygen cylinder. What measure should the nurse implement to minimize the risk of injury?

• Ensure that the cylinder is always kept away from heat.

• Connect the cylinder to the client without changing the pressure.

• Roll the cylinder in a horizontal position when moving it.

• Remember to keep the valve of the cylinder turned on at all times.

A nurse is caring for a client receiving oxygen through a portable liquid-oxygen stroller. What measure should the nurse implement when operating the stroller?

• Refill the stroller using small oxygen cylinders.

• Reduce the pressure in the stroller before connecting it to the client.

• Take measures to keep the stroller upright at all times.

• Connect the tubing of the stroller to an electric plug.

The nurse is preparing to discharge a client who is on supplemental oxygen to his home. Which oxygen delivery system is widely used in home care settings for its safety and convenience?

• Hyperbaric chamber

• Large oxygen cylinder

• Wall outlet unit

• Concentrator

The nurse knows that when administering oxygen to an individual who is having difficulty breathing, the type of device that is used is critically important. What is the primary concern when delivering oxygen to a client?

• Ease of oxygen delivery

• Delivery of desired concentration

• Monitoring of ABGs

• Comfort of the client
