A nurse is admitting a client who is having an exacerbation of asthma.
When reviewing the provider's orders, the nurse recognizes that clarification is needed for which of the following prescribed medications?

Choice A rationale:

Metabolic alkalosis Metabolic alkalosis is characterized by an elevated pH (above the normal range of 7.35-7.45) and an increased bicarbonate (HCO3) level (above the normal range of 22-28 mEq/L). In this case, the client's pH of 7.6 and HCO3 level of 32 mEq/L indicate a primary metabolic alkalosis. It can be caused by excessive bicarbonate intake, loss of acid (as in vomiting or excessive diuretic use), or other factors that result in an excess of bicarbonate in the body. The PaCO2 level is within the normal range (35-45 mm Hg), which is consistent with compensatory hypoventilation seen in metabolic alkalosis.

Choice B rationale:

Metabolic acidosis Metabolic acidosis is characterized by a decreased pH and bicarbonate level. The client's ABG results do not align with metabolic acidosis. In this case, the pH is elevated, and the bicarbonate level is above the normal range.

Choice C rationale:

Respiratory alkalosis Respiratory alkalosis is characterized by an elevated pH and decreased PaCO2. The client's ABG results show a normal PaCO2 of 40 mm Hg, which does not align with respiratory alkalosis. In respiratory alkalosis, you would typically see a lower PaCO2.

Choice D rationale:

Respiratory acidosis Respiratory acidosis is characterized by a decreased pH and elevated PaCO2. The client's ABG results do not align with respiratory acidosis. In this case, the PaCO2 is within the normal range, and the pH is elevated, which is not indicative of respiratory acidosis.

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.
