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 D

Explanation

Choice A rationale:
High lipase is not a typical laboratory finding related to overusing prescribed diuretics and a sodium level of 127 mEq/L. Lipase is an enzyme involved in lipid digestion and is more relevant in assessing pancreatic function.
Choice B rationale:
High creatine kinase-MB (CK-MB) is not associated with overusing prescribed diuretics or hyponatremia (low sodium level). CK-MB is a specific marker for myocardial damage and is usually elevated in conditions like myocardial infarction.
Choice C rationale:
Low hemoglobin is not directly related to overusing prescribed diuretics and a sodium level of 127 mEq/L. Low hemoglobin may indicate anemia or other hematological issues but this is not a typical finding in this scenario.
Choice D rationale:
The correct answer is low urine specific gravity. Overusing diuretics can lead to excessive urination, causing the urine to become more dilute with lower specific gravity. A low urine specific gravity indicates decreased urine concentration and can be a sign of fluid and electrolyte imbalances, including hyponatremia.

A. Provide pin care when the client is 4 hours postoperative. B. Remove the weights from the traction while repositioning the client in bed. C. Assess the client's circulation every 4 hours. D. Request the client to perform ankle exercises on the affected extremity.

Correct Answer is C

Explanation

Choice A rationale:

Providing pin care when the client is 4 hours postoperative is not appropriate. The client has just undergone skeletal traction placement, and pin care is usually initiated after 24 hours to allow for initial wound healing.

Choice B rationale:

Removing the weights from the traction while repositioning the client in bed is unsafe and not recommended. The weights should remain in place to provide continuous traction and alignment for the fractured hip.

Choice C rationale:

Assessing the client's circulation every 4 hours is essential to monitor for any signs of impaired circulation, such as swelling, pallor, or decreased pulses. Early detection of circulatory compromise is critical to prevent complications like compartment syndrome.

Choice D rationale:

Requesting the client to perform ankle exercises on the affected extremity is not appropriate after skeletal traction placement. Ankle exercises could disrupt traction and hinder the healing process of the fractured hip.
