A nurse is reviewing the ABGs of a client who has pneumonia. The nurse should identify which of the following findings is an indication of respiratory acidosis.
PaO2 86 mm Hg.
pH 7.4.
HCO3 16 mEq/L.
PaCO2 58 mm Hg.
The Correct Answer is D
Choice A rationale:
A PaO2 value of 86 mm Hg is within the normal range (80-100 mm Hg) and does not indicate respiratory acidosis. PaO2 measures the partial pressure of oxygen in arterial blood.
Choice B rationale:
A pH of 7.4 is within the normal range (7.35-7.45) and does not indicate respiratory acidosis. The pH reflects the acidity or alkalinity of the blood.
Choice C rationale:
An HCO3 (bicarbonate) level of 16 mEq/L is within the normal range (22-28 mEq/L) and does not indicate respiratory acidosis. HCO3 is a measure of the metabolic component of the body's acid-base balance.
Choice D rationale:
This is the correct choice. A PaCO2 value of 58 mm Hg is elevated and indicates respiratory acidosis. PaCO2 measures the partial pressure of carbon dioxide in arterial blood, and an elevated value suggests the presence of excess carbon dioxide, leading to acidosis.

Correct Answer is B
Explanation
Choice A rationale:
Is not a safe fall prevention strategy. Securing cords under carpeting can create tripping hazards. It is better to keep cords away from commonly used walking paths or use cord covers to prevent falls.
Choice B rationale:
Purchasing a skid-proof bathtub mat is a good fall-prevention strategy for an older adult client. It helps prevent slipping and falling in the bathroom, which is a common area for accidents in older adults.
Choice C rationale:
Is not a recommended fall prevention strategy. Leather soles can be slippery on smooth surfaces, increasing the risk of falls. Instead, the client should wear shoes with rubber soles that provide better traction.
Choice D rationale:
Is not the best option. Throw rugs, even with rubber backing, can still shift or bunch up, posing a tripping hazard. It's safer to avoid using throw rugs altogether or ensure they are firmly secured to the floor.
Correct Answer is C
Explanation
Choice A rationale:
A three-prong plug attached to the electrical cord of the client's bed is not a safety hazard. It is a standard plug type used in many electrical devices and poses no immediate danger if properly installed.
Choice B rationale:
Inserting a protective cover into an unused outlet is actually a safety measure to prevent electrical accidents. It is not a hazard but a recommended practice.
Choice C rationale:
Plugging an IV pump into an outlet near a sink is a safety hazard. Water and electricity are a dangerous combination, and any spill or leakage around the outlet could lead to electrical shock or damage to the equipment.
Choice D rationale:
Coiling and securing an electrical cord to the floor can be a potential tripping hazard, but it is not as hazardous as having an electrical device near a sink. Tripping hazards can cause falls, while the combination of water and electricity is more likely to cause serious injuries.
