The nurse should initiate intervention b) cover wounds with moist sterile dressings, before transferring the client with burns to a burn center.
When a client has burns to a large portion of their body, it is important to initiate appropriate interventions before transferring them to a burn center for specialized care. The priority intervention in this scenario is to cover the client's wounds with moist sterile dressings to prevent further tissue damage and to promote wound healing.
This will also help to prevent infection and reduce pain. While administering IV fluids and checking pedal pulses are important interventions, they are not the priority in this situation.
Pain management is also important, but it can be addressed once the client has arrived at the burn center and a more comprehensive assessment can be performed. So b is correct answer.

What could be potential laboratory findings in a patient who is on anticoagulant therapy and has a prolonged INR (International Normalized Ratio) and PPT (Partial Thromboplastin Time), but a normal aPTT (Activated Partial Thromboplastin Time)?
The potential laboratory findings in a patient on anticoagulant therapy with a prolonged INR and PTT, but a normal aPTT may indicate an increased risk of bleeding.
The INR and PTT are commonly used to monitor anticoagulant therapy. A prolonged INR indicates that the patient's blood is taking longer than usual to clot, and a prolonged PTT indicates a deficiency in clotting factors. These results suggest that the patient may be at an increased risk of bleeding. A normal aPTT suggests that the clotting time for the intrinsic pathway of coagulation is normal, which is not typical in patients on anticoagulant therapy. This discrepancy may be due to the specific anticoagulant medication the patient is taking or an underlying clotting disorder. Additional laboratory tests may be necessary to determine the cause of the abnormal results and adjust the patient's treatment accordingly.

Overview: When do inner ear structures reach full adult size?
Inner ear structures that reach their full adult size are the cochlea and vestibular system.
The cochlea, which is responsible for hearing, achieves its adult size by the end of the second trimester of pregnancy, around 24 to 28 weeks gestation. This early development allows the fetus to begin experiencing auditory stimuli before birth.
The vestibular system, which plays a role in balance and spatial orientation, continues to develop throughout the third trimester and after birth. The three semicircular canals, utricle, and saccule within the vestibular system reach their adult size by approximately 2 to 3 years of age.
Overall, while the cochlea attains full adult size during the prenatal period, the vestibular system continues to develop postnatally. This difference in development timelines reflects the functions of these structures, as hearing becomes more critical in utero, while balance and spatial orientation are essential for a child's motor development during early childhood.
