Correct Answer : A,B,D,G,H
A. Coagulation Studies: This client has liver and spleen lacerations with blood noted in the peritoneum, increasing the risk of coagulopathy due to active bleeding. The liver is responsible for producing clotting factors, and an injury may impair coagulation. The client also has a low hemoglobin (9.3 g/dL) and hematocrit (30%), suggesting ongoing blood loss. Monitoring prothrombin time (PT), international normalized ratio (INR), and activated partial thromboplastin time (aPTT) can guide transfusion therapy (e.g., fresh frozen plasma or platelets).
B. Type and Screen: This client has evidence of hemorrhagic shock (tachycardia, narrow pulse pressure, low hemoglobin/hematocrit) and may require blood transfusion. Type and screen determines ABO blood type and Rh factor to ensure availability of compatible blood products. If bleeding worsens, crossmatching blood would be necessary for transfusion.
C. Urine osmolality: Not a priority in this trauma case. Urine osmolality assesses kidney function and hydration status but does not provide urgent information about blood loss, shock, or ventilation status.
D. Complete Blood Count (CBC): Provides serial hemoglobin and hematocrit (H&H) monitoring to assess for ongoing internal bleeding. White blood cell (WBC) count helps detect infection or inflammation post-operatively. Platelets are critical for clotting and must be monitored, especially in trauma patients at risk for coagulopathy.
E. Blood culture: Used to detect bloodstream infections (sepsis), which is not an immediate concern in this trauma patient. While infection risk is relevant postoperatively, it is not a priority test for acute trauma care.
F. Lipid panel: Lipid panels evaluate cholesterol and triglyceride levels, which are irrelevant in acute trauma management.
G. Arterial Blood Gas (ABG): This client is intubated and ventilated, making ABG analysis essential for evaluating: Oxygenation (PaO₂, SaO₂) and ventilation (PaCO₂), Acid-base balance (pH, bicarbonate levels). Early detection of metabolic acidosis, which may indicate shock or inadequate perfusion.
H. Electrolytes: Trauma and fluid resuscitation can cause electrolyte imbalances, leading to cardiac arrhythmias, fluid shifts, and metabolic disturbances. Potassium (K⁺) is Essential to monitor due to IV fluids with potassium chloride infusion. Sodium (Na⁺), chloride (Cl⁻), and bicarbonate (HCO₃⁻) are crucial in assessing fluid status and acid-base balance. Lactate levels (part of a metabolic panel) can indicate tissue hypoxia and worsening shock.

Correct Answer is ["B","E","G"]
Explanation
Chest pain described as pressure and tightness that is unrelieved with rest: Chest pain that is described as tightness and pressure, particularly when unrelieved by rest, is a classic presentation of acute coronary syndrome (ACS), which includes conditions such as unstable angina or myocardial infarction (MI). This is a red flag symptom, as it indicates a need for immediate medical attention to rule out life-threatening conditions like MI, which can be fatal without timely intervention.
Rapid shallow breaths: Rapid and shallow breathing can be a response to acute pain, particularly in a situation involving cardiovascular stress. It may be indicative of the body's attempt to compensate for inadequate oxygenation due to cardiac ischemia, hypoxia, or anxiety.
Pain 7/10, tightness and pressure in the chest: A pain rating of 7/10 demands immediate evaluation and management, as it could indicate an evolving cardiovascular event. Moreover, tightness and pressure are specific descriptors of pain seen in ischemic heart disease, where there is reduced blood flow to the heart muscle, leading to discomfort due to oxygen deprivation.
Correct Answer is B
Explanation
A. Scabies requires contact precautions, not airborne isolation.
B. Tuberculosis (TB) is transmitted via airborne particles, requiring a negative airflow room and use of a particulate respirator (e.g., N95 mask).
C. Herpes simplex virus type II is transmitted through direct contact and does not require airborne precautions.
D. Scarlet fever is spread through respiratory droplets, but it does not require airborne precautions or a negative pressure room.
