A client receiving mechanical ventilation has a pH of 7.26, PaCO2 of 68 mm Hg, and a PaO2 of 92 mm Hg. Which intervention should the nurse implement?Reference Range:
Arterial Blood Gas (ABG)
pH [Adult/child: 7.35 to 7.45]
PaCO2 [Adult/child: 35 to 45 mm Hg)
HCO- [Adult/child: 21 to 28 mEq/L (21 to 28 mmol/L)] PaO2 [Adult/child: 80 to 100 mm Hg)

Increase rate of ventilation.

Decrease expiratory flow time.

Increase ventilator tidal volume.

Decrease expiratory pressure.

Answer and Explanation

The Correct Answer is A

Rationale

A. The client's pH is low (acidotic), and the PaCO2 is high (respiratory acidosis). Increasing the rate of ventilation (respiratory rate) can help to decrease PaCO2 by increasing alveolar ventilation, thereby helping to correct respiratory acidosis.

B. Expiratory flow time affects the time available for exhalation. While this may affect the overall mechanics of ventilation, it is not directly targeting the primary issue of elevated PaCO2 and acidosis.

C. Increasing tidal volume increases the volume of air delivered with each breath. This can improve ventilation efficiency but may not address the underlying problem of elevated PaCO2 unless it leads to increased minute ventilation.

D. Expiratory pressure is related to positive end-expiratory pressure (PEEP), which helps maintain alveolar recruitment and improve oxygenation. Decreasing expiratory pressure may not directly address the elevated PaCO2 and acidosis.

Correct Answer is A

Explanation

Rationale

A. Osteoarthritis is characterized by the gradual destruction of joint cartilage. Cartilage serves as a cushion between the bones in a joint, and its deterioration leads to pain, stiffness, and reduced joint function. As the cartilage wears away, bones may rub directly against each other, causing further pain and damage.

B. Osteoarthritis is primarily a degenerative condition rather than an inflammatory one. While mild inflammation can occur in OA, it is not as prominent as in autoimmune conditions like rheumatoid arthritis. In OA, inflammation is secondary to cartilage damage rather than a primary driver of the disease process.

C. Loss of bone mineral density is more characteristic of osteoporosis, a condition where bones become weak and brittle. Osteoporosis involves a decrease in bone mass throughout the skeleton, whereas osteoarthritis specifically targets the joints and affects cartilage rather than bone density.

D. An infectious process in the synovial fluid could indicate septic arthritis, which is characterized by infection in the joint space. This is typically associated with acute symptoms such as severe joint pain, swelling, warmth, and fever.

A. Phototherapy B. Administration of lithium C. Consciousness raising D. Cognitive behavioral therapy E. Electroconvulsive therapy F. Animal therapy

Correct Answer is ["A","C","D","F"]

Explanation

A. Phototherapy involves exposure to specific wavelengths of light to help regulate mood and alleviate symptoms of depression, anxiety, or sleep disorders. It can be particularly beneficial in a hospital setting where natural light exposure may be limited, potentially aiding in mood stabilization and improving sleep patterns.
B. Lithium is a mood stabilizer commonly used to treat bipolar disorder. While the client's symptoms and presentation do not immediately suggest bipolar disorder, lithium could be considered if there are indications of mood instability or severe emotional dysregulation that are not adequately controlled by other medications.
C. Consciousness raising refers to increasing awareness and understanding of one's thoughts, emotions, and behaviors. In the context of therapy, it can help the client process traumatic experiences, gain insight into their reactions, and develop coping strategies. This approach can be integrated into various forms of psychotherapy.
D. CBT is a structured form of psychotherapy that focuses on identifying and modifying dysfunctional thought patterns and behaviors. It has been shown to be effective in treating anxiety, depression, PTSD, and other trauma-related disorders by helping individuals challenge negative thoughts and develop healthier coping mechanisms.
E. ECT involves passing electrical currents through the brain to intentionally trigger a brief seizure. It is primarily used for severe depression or other mental illnesses that have not responded to other treatments. Given the client's presentation and the availability of less invasive treatments, ECT would generally not be considered unless her condition worsens significantly and other therapies are ineffective or contraindicated.
F. Animal therapy involves interacting with animals, such as therapy dogs or horses, to improve mood, reduce stress, and provide emotional support. This type of therapy can be beneficial for individuals experiencing trauma or emotional distress, offering comfort and companionship.
