Respiratory alkalosis

Metabolic alkalosis

Metabolic acidosis

Respiratory acidosis

Answer and Explanation

The Correct Answer is C

A nurse reviewing the laboratory results of a client who has DKA should identify that the client's ABG results of pH 7.30, PaCO₂ 34 mm Hg and HCO₃ 21 mEq/L indicate metabolic acidosis. Metabolic acidosis is an acid-base imbalance characterized by a low pH (less than 7.35) and a low bicarbonate level (less than 22 mEq/L).

The other options are not correct.

a) Respiratory alkalosis is an acid-base imbalance characterized by a high pH (greater than 7.45) and a low PaCO₂ (less than 35 mm Hg).

b) Metabolic alkalosis is an acid-base imbalance characterized by a high pH (greater than 7.45) and a high bicarbonate level (greater than 26 mEq/L).

d) Respiratory acidosis is an acid-base imbalance characterized by a low pH (less than 7.35) and a high PaCO₂ (greater than 45 mm Hg).

Correct Answer is C

Explanation

c. Instruct the client to stand up slowly.

Explanation:

The correct answer is c. Instruct the client to stand up slowly.

Prazosin is an alpha-1 adrenergic blocker used to treat hypertension and benign prostatic hyperplasia. One of the common side eﬀects of prazosin is orthostatic hypotension, which can cause a drop in blood pressure when changing positions from lying or sitting to standing.

In this scenario, the client's blood pressure is 100/60 mm Hg, which indicates hypotension. To prevent a sudden drop in blood pressure and related symptoms such as dizziness or fainting, the nurse should instruct the client to stand up slowly. This allows the body time to adjust to the change in position and minimizes the risk of orthostatic hypotension.

Option a, administering a reversal agent, is not necessary in this situation. Reversal agents are used to counteract the eﬀects of specific medications when there is a need to rapidly reverse their actions. There is no indication in the scenario that the client requires a reversal agent.

Option b, initiating cardiac monitoring, is not warranted based solely on a blood pressure reading of 100/60 mm Hg. Cardiac monitoring is typically indicated when there are specific cardiac concerns or symptoms, which are not mentioned in the scenario.

Option d, informing the client to report urinary retention, is a potential side eﬀect of prazosin but is not the most appropriate action to take in this situation. The client's blood pressure is the immediate concern, and addressing orthostatic hypotension by instructing the client to stand up slowly is the appropriate action.

By instructing the client to stand up slowly, the nurse promotes safety and minimizes the risk of orthostatic hypotension, allowing the client to adjust to the change in position and reduce the likelihood of experiencing symptoms related to low blood pressure.
