A nurse is caring for a patient who has the following arterial blood values: pH 7.12, PaO 56 mm Hg, PaCO 65 mm Hg, and HCO - 22 mEq/L (22 mmol/L). Which clinical situation does the nurse correlate with these values?

A.Prone positioning and postural drainage are typically not appropriate interventions for a client 1 day postoperative following an open thoracotomy, as this could place stress on the incision site and cause discomfort or injury.

B.High-Fowler's position facilitates lung expansion, which can improve ventilation and oxygenation. Encouraging the use of an incentive spirometer and promoting coughing helps clear secretions and expand the lungs, addressing the mild respiratory acidosis indicated by the ABG results (pH 7.31 and PaCO2 50 mm Hg).

C.Increasing oxygen to 70% is not appropriate, as the PaO2 level is within normal limits (93 mm Hg). The client's issue appears to be related more to ventilation (indicated by the elevated PaCO2) rather than oxygenation, so additional oxygen would not address the underlying cause and could lead to oxygen toxicity if used long-term.

D.A nonrebreather mask delivers a high concentration of oxygen, which is not necessary in this case since the client’s PaO2 is already adequate. The primary issue is not a lack of oxygen but rather the retention of CO2, so promoting ventilation and lung expansion through positioning and respiratory exercises is more appropriate.

A. A 60-year-old client with gastritis:

Gastritis is inflammation of the stomach lining and typically does not directly increase the risk of skin infections. However, if the gastritis is due to an underlying condition that affects the immune system, such as an autoimmune disorder, the client may have a slightly higher risk of infections, including skin infections, compared to a healthy individual of the same age. Overall, gastritis alone is not a significant risk factor for skin infections compared to the other options.

B. A 20-year-old client with a closed tibia fracture:

A closed tibia fracture refers to a broken shinbone that does not break the skin. While fractures themselves do not necessarily increase the risk of skin infections, they can indirectly contribute to infection risk if there are complications such as open wounds, surgical procedures, or prolonged immobilization. In this case, because the fracture is closed and presumably not complicated by open wounds or surgery, this client is not significantly prone to skin infections compared to the other options.

C. A 55-year-old client taking an ACE inhibitor:

ACE (angiotensin-converting enzyme) inhibitors are medications commonly used to treat conditions like high blood pressure and heart failure. While these medications can cause side effects like a dry cough or skin rash in some individuals, they do not directly increase the risk of skin infections. Unless the client experiences a severe allergic reaction or develops a rash that becomes infected, the use of ACE inhibitors alone is not a major risk factor for skin infections compared to the other options.

D. A 35-year-old client receiving chemotherapy:

Chemotherapy is a treatment for cancer that works by targeting rapidly dividing cells, including cancer cells but also affecting some healthy cells like those in the bone marrow responsible for producing white blood cells. As a result, chemotherapy can significantly weaken the immune system, leading to a higher risk of infections, including skin infections. Patients undergoing chemotherapy are particularly susceptible to bacterial, fungal, and viral infections due to their compromised immune response. Therefore, the 35-year-old client receiving chemotherapy is the most prone to skin infections among the options given due to their weakened immune system.
