A nurse is caring for a client who is hyperventilating and has the following ABG results: pH 7.50 (7.35 to 7.45), PaCO₂ 29 mm Hg (35 to 45 mm Hg), and HCO₃ 25 mEq/L (21 to 28 mEq/L). The nurse should identify that the client has which of the following acid-base imbalances?

Respiratory acidosis

Respiratory alkalosis

Metabolic acidosis

Metabolic alkalosis

Answer and Explanation

The Correct Answer is B

Choice A Reason:

Respiratory acidosis is characterized by a low pH (below 7.35) and an elevated PaCO₂ (above 45 mm Hg). This condition occurs when there is an accumulation of carbon dioxide in the blood due to hypoventilation or impaired lung function. In this case, the client’s pH is elevated, and PaCO₂ is low, which does not align with respiratory acidosis.

Choice B Reason:

Respiratory alkalosis is indicated by a high pH (above 7.45) and a low PaCO₂ (below 35 mm Hg). This condition results from hyperventilation, which causes excessive exhalation of carbon dioxide. The client’s ABG results show a pH of 7.50 and a PaCO₂ of 29 mm Hg, consistent with respiratory alkalosis.

Choice C Reason:

Metabolic acidosis is characterized by a low pH (below 7.35) and a low HCO₃ (below 21 mEq/L). This condition occurs due to an accumulation of acids or a loss of bicarbonate in the body. The client’s pH is elevated, and HCO₃ is within the normal range, which does not indicate metabolic acidosis.

Choice D Reason:

Metabolic alkalosis is indicated by a high pH (above 7.45) and a high HCO₃ (above 28 mEq/L). This condition results from an excess of bicarbonate or a loss of acids. The client’s pH is elevated, but HCO₃ is within the normal range, which does not support a diagnosis of metabolic alkalosis.

Correct Answer is A

Explanation

Choice A Reason:

A red tag is used to label those who cannot survive without immediate treatment but who have a chance of survival. The child’s respiratory rate of 8/min, unresponsiveness to verbal commands, and groaning to painful stimuli indicate severe injuries that require urgent medical attention. Immediate intervention is necessary to address potential life-threatening conditions.

Choice B Reason:

A yellow tag is assigned to those who require observation and possible later re-triage. Their condition is stable for the moment, and they are not in immediate danger of death. Given the child’s critical condition, a yellow tag would not be appropriate as it suggests the child can wait for treatment, which is not the case here.

Choice C Reason:

A green tag is for the “walking wounded” who will need medical care at some point after more critical injuries have been treated. This tag is not suitable for the child in question, as their condition is far from minor and requires immediate attention.

Choice D Reason:

A black tag is used for the deceased or those whose injuries are so severe that they are not expected to survive despite receiving care. While the child’s condition is critical, they still have a chance of survival with immediate treatment, making a black tag inappropriate.

A. Use an electric shaver. B. Avoid crowds. C. Take temperature weekly. D. Consume a low-residue diet. E. Monitor for bruising.

Correct Answer is ["A","B","E"]

Explanation

Choice A Reason:

Using an electric shaver is recommended for clients who have received chemotherapy because it reduces the risk of cuts and bleeding. Chemotherapy can lower platelet counts, leading to an increased risk of bleeding. Traditional razors can cause nicks and cuts, which can be problematic for clients with low platelet counts.

Choice B Reason:

Avoiding crowds is crucial for clients who have received chemotherapy because their immune systems are often weakened, making them more susceptible to infections. Crowded places increase the risk of exposure to pathogens, which can lead to serious infections in immunocompromised individuals.

Choice C Reason:

Taking temperature weekly is not sufficient for clients who have received chemotherapy. These clients are at a higher risk of infections, and any sign of fever should be monitored closely. It is generally recommended to take the temperature daily or more frequently if the client feels unwell.

Choice D Reason:

Consuming a low-residue diet is not typically necessary for clients who have received chemotherapy unless they are experiencing specific gastrointestinal issues. A balanced diet with adequate nutrients is usually recommended to support overall health and recovery.

Choice E Reason:

Monitoring for bruising is important for clients who have received chemotherapy because it can indicate low platelet counts or other bleeding disorders. Early detection of bruising can help in managing and preventing more serious bleeding complications.
