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.

Answer and Explanation

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 C

Explanation

Choice A rationale:

Difficulty maintaining personal hygiene is not typically an early indication of mild Alzheimer's disease. In the early stages, individuals can still manage personal hygiene.

Choice B rationale:

Difficulty handling finances may occur in the later stages of Alzheimer's disease, but it is not an early indication. In the early stages, the person might still manage financial matters.

Choice C rationale:

Difficulty remembering the names of new friends is a common early sign of mild Alzheimer's disease. It reflects the impairment of short-term memory that often occurs in the early stages of the disease.

Choice D rationale:

Difficulty driving to and from familiar places is more likely to be a mid-to-late-stage symptom of Alzheimer's disease. In the early stages, individuals might still drive familiar routes with minimal difficulty.

A. Cross the client's legs when sitting in the recliner. B. Provide a heating pad to the operative hip. C. Place a pillow between the legs when turning the client to their side. D. Have the client lean forward when assisting them out of the bed.

Correct Answer is C

Explanation

Choice A rationale:
The nurse should not cross the client's legs when sitting in the recliner following a total left hip arthroplasty. Crossing the legs can put strain on the operative hip and may increase the risk of dislocation or other complications.
Choice B rationale:
Providing a heating pad to the operative hip is not recommended. Heat can increase blood flow to the area and may lead to increased swelling and potential complications in the postoperative period.
Choice C rationale:

Placing a pillow between the legs when turning the client to their side is the correct action. This technique is known as the "abduction pillow”. or "wedge pillow.”. It helps maintain proper hip alignment and prevents the operated leg from crossing the midline, reducing the risk of dislocation and promoting healing.
Choice D rationale:
Having the client lean forward when assisting them out of the bed is not appropriate after a total left hip arthroplasty. Leaning forward can put strain on the hip joint and increase the risk of injury.
