A nurse is reviewing the laboratory results of a client who was hyperventilating during a panic attack.
Which of the following arterial blood gas values should the nurse expect?
pH 7.50 and HCO3 31 mm Hg.
pH 7.30 and HCO3 19 mm Hg.
pH 7.47 and PaCO2 31 mm Hg.
pH 7.32 and PaCO2 50 mm Hg.
The Correct Answer is C
The correct answer is: C.
Choice A reason: A pH of 7.50 and HCO3 of 31 mm Hg suggest a metabolic alkalosis due to the high bicarbonate level. However, during a panic attack, hyperventilation leads to respiratory alkalosis, not metabolic, due to the excessive exhalation of CO2, which is not consistent with this option.
Choice B reason: A pH of 7.30 and HCO3 of 19 mm Hg indicate a metabolic acidosis due to the low bicarbonate level. This is not typically associated with hyperventilation during a panic attack, which usually causes respiratory alkalosis, characterized by a decrease in CO2 levels and an increase in pH.
Choice C reason: A pH of 7.47 and PaCO2 of 31 mm Hg are indicative of respiratory alkalosis, which is expected during hyperventilation as a result of a panic attack. Hyperventilation causes a decrease in carbon dioxide (PaCO2) levels, leading to an increase in pH. The normal ranges for arterial blood gases are: pH 7.35-7.45, PaCO2 35-45 mm Hg, and HCO3 22-26 mEq/L.
Choice D reason: A pH of 7.32 and PaCO2 of 50 mm Hg suggest respiratory acidosis due to the elevated PaCO2 level. This would be more consistent with hypoventilation, which is not the case during a panic attack where hyperventilation occurs.

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 D
Explanation
Choice A rationale:
Having the client cough and expectorate secretions is a reasonable intervention for managing respiratory distress, but it is not the top priority. The nurse should first assess the client's overall respiratory status to determine the severity of the problem.
Choice B rationale:
Instructing the client to use a pursed-lip breathing technique is a helpful strategy to improve breathing in some cases. However, it should not be the top priority when a client is experiencing difficulty breathing. Assessment should come first.
Choice C rationale:
Increasing the oxygen flow to 3 L/min without a proper assessment is not advisable. It's essential to evaluate the client's respiratory status before making any adjustments to the oxygen therapy.
Choice D rationale:
"Evaluate the client's respiratory status" is the correct response. When a client with COPD and oxygen therapy reports difficulty breathing, the nurse's priority is to assess the client's respiratory status. This assessment will help determine the cause of the breathing difficulty and guide appropriate interventions. The nurse should also check the oxygen saturation levels, respiratory rate, and auscultate lung sounds to assess the severity of the issue.
