A nurse is caring for a client whose arterial blood gas results show the following results:. pH: 7.2. PaCO2: 50 mm Hg. HCO3: 24 mEq/L. The nurse should identify the client is experiencing which of the following acid-base conditions?
Respiratory acidosis.
Metabolic alkalosis.
Metabolic acidosis.
Respiratory alkalosis.
The Correct Answer is A
Choice A rationale:
The client's arterial blood gas (ABG) results indicate a low pH (acidemia) and high PaCO2, which is characteristic of respiratory acidosis. Respiratory acidosis occurs when there is inadequate removal of carbon dioxide (CO2) from the body, leading to an accumulation of CO2 and a decrease in pH. In this case, the high PaCO2 (50 mm Hg) indicates that the client is retaining carbon dioxide, likely due to impaired ventilation. The normal pH range is 7.35 to 7.45, and the normal PaCO2 range is 35 to 45 mm Hg. These ABG values reflect an acid-base imbalance in the respiratory system, specifically, respiratory acidosis.
Choice B rationale:
Metabolic alkalosis is characterized by an elevated pH and an increase in bicarbonate (HCO3) levels. This is not the condition described in the client's ABG results, as the pH is low (acidemic) and HCO3 levels are within the normal range (24 mEq/L).
Choice C rationale:
Metabolic acidosis is characterized by a low pH and a decreased HCO3 level. The client's ABG results do not align with metabolic acidosis since the pH is low (acidemic) and the HCO3 level is within the normal range (24 mEq/L).
Choice D rationale:
Respiratory alkalosis is characterized by a high pH and low PaCO2. The client's ABG results do not match this condition as the pH is low (acidemic) and the PaCO2 is high (50 mm Hg), indicating respiratory acidosis. Therefore, choice A, respiratory acidosis, is the correct interpretation of the ABG results.

Correct Answer is C
Explanation
Choice A rationale:
The nurse should not instruct the client to rest with the legs above heart level. While elevating the legs can be helpful for managing symptoms of peripheral artery disease (PAD), it is not a suitable choice for older adults, especially those with heart conditions. It can put additional strain on the heart and may not be appropriate for all clients. Elevation of the legs should be done with caution and under healthcare provider guidance.
Choice B rationale:
The nurse should not advise the client to wear antiembolic stockings during the day. Antiembolic stockings, also known as compression stockings, are primarily used for venous insufficiency and the prevention of deep vein thrombosis (DVT). They may not be effective or necessary for the management of PAD. It's important to tailor the instructions to the specific condition, and in the case of PAD, other strategies may be more appropriate.
Choice C rationale:
The correct answer is choice C. The nurse should instruct the client to adjust the thermostat so that the environment is warm. This is an important recommendation for clients with PAD because keeping the extremities warm can help improve circulation and reduce symptoms. Cold environments can exacerbate the vasoconstriction associated with PAD, leading to more discomfort. Maintaining a warm environment is a simple and effective measure for symptom management.
Choice D rationale:
The nurse should not recommend applying a heating pad on a low setting to help relieve leg pain. While heat can provide temporary relief for muscle pain, it may not be the best option for clients with PAD. Applying heat directly to the affected area can sometimes lead to burns or skin damage, especially in older adults who may have decreased sensation. Heat should be used cautiously, and other methods like keeping the environment warm are preferred.
Correct Answer is B
Explanation
Choice A rationale:
Planning to have the client lay down for 1 hour after meals is not an appropriate intervention for a client with COPD. It may increase the risk of aspiration and worsen their breathing difficulties.
Choice C rationale:
Encouraging the client to use the upper chest for respiration is not the best approach for a client with COPD. Pursed-lip breathing helps improve oxygen exchange and decreases air trapping, which is more effective in managing COPD.
Choice D rationale:
Restricting the client's fluid intake to less than 1 Vday is not a suitable intervention for a client with COPD. Dehydration can lead to thicker mucus, making it harder to breathe
