A nurse is caring for a client who has deep vein thrombosis (DVT) of their right lower leg. Which of the following manifestations should the nurse expect? (Select All that Apply.)

A. Respiratory alkalosis, fully compensated: pH is low normal (7.35), and the bicarbonate (HCO3-) level is low (21 mEq/L), indicating metabolic acidosis, not respiratory alkalosis. Respiratory alkalosis would present with a high pH and low PaCO2.
B. Metabolic acidosis, partially compensated: The pH is slightly acidic (7.35), and the bicarbonate level is low (21 mEq/L), indicating metabolic acidosis. The PaCO2 level is normal, suggesting partial compensation by the respiratory system, but the body has not fully compensated for the acidosis yet.
C. Respiratory acidosis, fully compensated: Respiratory acidosis would present with an elevated PaCO2 and a low pH, which is not the case here. The PaCO2 is normal at 40 mmHg, so this option is incorrect.
D. Metabolic acidosis, fully compensated: While the client does have metabolic acidosis, the respiratory system has not fully compensated for the acidosis, as evidenced by the normal PaCO2 level. Therefore, the compensation is partial, not full.

A. Decreased visual acuity: Decreased visual acuity is a significant factor in head injuries in older adults. Poor vision increases the likelihood of falls and accidents, as individuals are less able to detect obstacles or changes in their environment, leading to an increased risk of injury, including head trauma.
B. Motor vehicle crashes: While motor vehicle accidents can lead to head injuries, they are not as prevalent in older adults compared to other causes such as falls. Older adults are more likely to sustain head injuries from falls rather than from motor vehicle crashes, especially since they may not be as active in driving or are more cautious on the road.
C. Polypharmacy: Polypharmacy, or the use of multiple medications, is a common issue in older adults and can significantly contribute to the risk of falls and head injuries. Certain medications, such as sedatives, antihypertensives, and medications affecting balance or cognition, can increase the risk of dizziness, confusion, and falls, leading to head trauma.
D. Weakness: Muscle weakness, particularly in the lower extremities, is common in older adults and increases the risk of falls. Weakness can impair balance and coordination, making it harder for individuals to prevent falls or recover from them, resulting in head injuries.
E. Chronic hypertension: While chronic hypertension is a risk factor for cardiovascular events such as stroke, it is not a direct cause of head injuries in older adults. Hypertension may contribute to falls indirectly by affecting the ability to maintain balance due to related health complications, but it is not a primary cause of head injuries.
F. Previous military experience: Military experience is not a typical risk factor for head injuries in older adults. Although previous trauma or combat exposure could result in earlier injuries, it is not a common cause of head injuries in older adults compared to other factors like falls, medication use, or weakness.
