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:
Tender, bleeding gums could be a sign of phenytoin-induced gingival hyperplasia, a serious adverse effect of phenytoin. This condition requires immediate medical attention to prevent further complications.
Choice B rationale:
Increased facial hair is not a common adverse effect of phenytoin and may not require immediate medical attention. It could be due to other factors or conditions.
Choice C rationale:
Constipation is a common side effect of many medications, including phenytoin. While it should be monitored, it does not require immediate reporting to the provider unless severe or persistent.
Choice D rationale:
A skin rash can be an adverse effect of phenytoin, but it does not necessarily require immediate reporting unless it is severe, accompanied by other symptoms, or indicative of a serious allergic reaction.
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.
