A nurse is reviewing the laboratory results of a client who was an unrestrained passenger in a motor-vehicle crash. The ABG results are as follows: pH 7.32, HCO3 24 mEq/L, PaCO2 48 mm Hg. The nurse should identify the client is experiencing which of the following acid-base imbalances?

Respiratory acidosis

Metabolic acidosis

Respiratory alkalosis

Metabolic alkalosis

Answer and Explanation

The Correct Answer is A

A) Respiratory acidosis: This condition is indicated by a low pH (7.32) and an elevated PaCO2 (48 mm Hg), while HCO3 remains normal (24 mEq/L). Respiratory acidosis occurs when there is an accumulation of carbon dioxide in the blood, usually due to hypoventilation or impaired gas exchange in the lungs.

B) Metabolic acidosis: Metabolic acidosis is characterized by a low pH and a decreased HCO3 level. In this scenario, the HCO3 level is normal, ruling out metabolic acidosis.

C) Respiratory alkalosis: Respiratory alkalosis is indicated by a high pH and a decreased PaCO2. In this case, the pH is low, and the PaCO2 is elevated, which contradicts the characteristics of respiratory alkalosis.

D) Metabolic alkalosis: Metabolic alkalosis would show a high pH and an elevated HCO3 level. Since the pH is low and the HCO3 is normal, this condition does not fit the criteria for metabolic alkalosis.

Correct Answer is C

Explanation

A) Place a sign on the client's door indicating visual impairment:
While indicating the client’s visual impairment to staff can be helpful, privacy and dignity should also be considered. Alternative methods to inform the staff without compromising the client's privacy should be used.

B) Provide the client with a brightly colored plate and utensils:
Brightly colored plates and utensils can help clients with partial vision impairment but may not be significantly beneficial for those who are fully visually impaired.

C) When ambulating with the client, grasp the client's arm above the elbow:
Grasping the client's arm above the elbow is an effective way to guide a visually impaired person. This allows the client to follow the nurse's movements more naturally and ensures better support and guidance.

D) Speak in an elevated tone of voice when providing care:
Elevating the tone of voice is unnecessary and may be misinterpreted as condescending. Clear, normal, and respectful communication is essential for all clients, regardless of visual impairment.

A. Drowsiness B. Diminished patellar reflexes C. Generalized muscle weakness D. Bradycardia

Correct Answer is D

Explanation

A) Drowsiness: While drowsiness can be a symptom of elevated magnesium levels, it is not the most critical finding to report immediately. Drowsiness can be observed with other conditions as well.

B) Diminished patellar reflexes: This can be indicative of hypermagnesemia, but it is a less immediate concern compared to other symptoms. Monitoring reflexes is important, but not the priority.

C) Generalized muscle weakness: Muscle weakness is a common symptom of elevated magnesium levels, but it is less urgent compared to cardiac issues. Although important, it does not pose an immediate risk like bradycardia.

D) Bradycardia: Elevated magnesium levels can cause serious cardiac complications, including bradycardia. This can be life-threatening and requires prompt attention to prevent severe outcomes, making it the priority to report to the provider.
