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 A
Explanation
Choice A rationale:
The nurse should maintain the affected leg elevated on several pillows to reduce swelling and promote venous return. Elevating the leg helps minimize edema, which can be beneficial for the healing process and overall comfort of the client.
Choice B rationale:
Instructing the client to wiggle the toes once every 4 hours is not necessary and may cause discomfort to the fractured tibia. Toe wiggling does not provide any significant benefit in this context and could potentially disrupt the healing process.
Choice C rationale:
Using a hair dryer to promote drying of the cast is not recommended. Applying heat to the fiberglass cast may alter its integrity and lead to uneven drying, potentially weakening the cast's support.
Choice D rationale:
Applying heat to the client's cast for pain relief is not advisable. Heat may also weaken the cast material and is unlikely to provide effective pain relief for a fractured tibia. Instead, the nurse should follow the prescribed pain management plan and use appropriate pain medications as ordered by the healthcare provider.
Correct Answer is A
Explanation
Choice A rationale:
The nurse should maintain the client in a semi-Fowler's position to promote comfort and reduce the risk of complications related to appendicitis. This position helps to decrease pressure on the abdomen and may alleviate pain by reducing tension on the abdominal muscles.
Choice B rationale:
Administering an enema 1 hour prior to surgery is not indicated for a client with appendicitis. Enemas are generally not recommended for clients with suspected or confirmed appendicitis as they can potentially worsen inflammation and cause perforation of the inflamed appendix.
Choice C rationale:
Applying a warm pack to the client's lower abdomen is contraindicated in appendicitis. Heat can exacerbate inflammation and should be avoided in such cases.
Choice D rationale:
Placing the client on a clear liquid diet is not appropriate for appendicitis. Clients with appendicitis are typically NPO (nothing by mouth) to avoid stimulating the gastrointestinal tract and reduce the risk of rupture if surgery is needed.
