According to the laboratory values, the client has
The Correct Answer is {"dropdown-group-1":"E","dropdown-group-2":"A","dropdown-group-3":"E"}
Rationale for correct choices:
• Anemia: The client’s hemoglobin (9.3 g/dL) and hematocrit (30%) are both below normal, which indicates a reduced oxygen-carrying capacity of the blood, consistent with anemia.
• Blood loss: The abdominal hematoma, distension, and need for fluid bolus suggest internal bleeding after trauma, leading to a significant drop in hemoglobin and hematocrit.
• Hemodilution from intravenous fluids: The client received large volumes of IV fluids (bolus and maintenance infusion), which dilute circulating red blood cells, worsening the anemia picture.
Rationale for incorrect choices:
• Acidosis: No arterial blood gas (ABG) results are available yet, so there is no evidence to confirm a metabolic or respiratory acidosis at this stage.
• Hypovolemia: The client initially showed low blood pressure and tachycardia, but stabilization with fluids improved her vitals; the lab values specifically indicate anemia, not pure hypovolemia.
• Disseminated intravascular coagulation: PT and PTT are within normal limits, with no signs of uncontrolled clotting or bleeding, so DIC is not supported.
• Rh factor sensitization: The client is B+, but there is no mention of pregnancy or transfusion reactions that would trigger Rh-related hemolysis.
• Pregnancy: No history, findings, or labs indicate pregnancy, so this option is unrelated to the client’s current trauma and blood results.
• Hypoxia: Oxygen saturation remains 98–100% on mechanical ventilation, showing adequate oxygenation despite anemia.
• Blood administration: While the client may need transfusion, labs reflect anemia caused by blood loss and hemodilution, not from receiving blood products.
• Immune response: There are no clinical or laboratory findings of immune-mediated destruction of red cells or inflammation causing the anemia.
• Clotting cascade: Normal PT and PTT show the coagulation pathway is intact, ruling out clotting disorders as the cause of low hemoglobin and hematocrit.
• Hypoventilation: The client is mechanically ventilated with normal oxygenation, and there is no evidence of hypoventilation contributing to her anemia.

Correct Answer is C
Explanation
A. Prone: Prone positioning limits assessment of spinal curvature, extremity alignment, and body symmetry because the client is lying on the abdomen, which can obscure certain postural deviations.
B. Sims: Sims position is primarily used for rectal or vaginal procedures and does not provide a full view of overall body alignment, making it less ideal for assessment purposes.
C. Supine: Supine position allows the client to lie flat on the back with the body fully supported. This position provides the best view of the head, neck, spine, shoulders, hips, and extremities for a comprehensive assessment of body alignment.
D. Fowlers: Fowlers position elevates the head and torso, which may alter natural spinal alignment and obscure an accurate assessment of posture and symmetry compared with a flat, supine position.
Correct Answer is C
Explanation
A. Use nasal or cough tissues followed by handwashing at all times: Hand hygiene and respiratory etiquette are important to reduce infection risk, but they are general preventive measures and not as critical as vaccination for high-risk clients with chronic respiratory diseases.
B. Ensure supplemental oxygen and respiratory medications are available at all times: Having medications and oxygen ready is important for managing acute symptoms, but it does not prevent illness or complications; it is part of ongoing disease management not prevention.
C. Get annual flu and pneumococcal vaccine polyvalent (PPSV23) vaccines: Vaccination is the most important preventive measure for clients with asthma, chronic bronchitis, or emphysema. These clients are at higher risk for respiratory infections, which can cause severe exacerbations, hospitalization, and complications.
D. Avoid large crowded areas during the colder months of the year: Limiting exposure can reduce infection risk but is a situational preventive measure. Vaccination provides broader and more effective protection against common respiratory pathogens.
