What test provides fast, precise measurement of the bone mass of the spine, femur, forearm, and total body to evaluate osteoporosis?

Choice A reason: Applying ice reduces swelling and pain in a possible fracture, which is beneficial but not the first priority. Ice application does not assess the limb’s viability or detect complications like vascular injury or nerve damage. A neurovascular check is critical to ensure circulation and nerve function before interventions like ice, which could mask symptoms.

Choice B reason: Elevating the arm minimizes swelling by promoting venous return, aiding in pain relief and reducing pressure. However, it is secondary to a neurovascular check, which assesses circulation, sensation, and movement. Elevation without confirming vascular integrity risks missing critical injuries like arterial compression, which could lead to ischemia if untreated.

Choice C reason: Notifying the health care provider is necessary for diagnostic imaging and treatment planning but is not the first action. A neurovascular check provides immediate data on limb status, guiding urgency of notification. Delaying assessment risks missing acute complications like compartment syndrome, which requires prompt intervention to prevent permanent damage.

Choice D reason: Performing a neurovascular check first assesses distal pulses, sensation, movement, and capillary refill, detecting complications like vascular occlusion or nerve injury from a possible fracture. Fractures can compress arteries or nerves, risking ischemia or neuropathy. Early identification ensures timely intervention, making this the priority before splinting or other actions to preserve limb function.

Choice A reason: Applying pediculicide lotion is inappropriate for tick removal, as it targets lice, not ticks. This could irritate the skin or prompt the tick to regurgitate, increasing the risk of pathogen transmission, such as Borrelia burgdorferi causing Lyme disease. Proper removal uses mechanical extraction to minimize infection, ensuring safe and effective tick removal without chemical interference.

Choice B reason: Using a hot ember to remove a tick is hazardous and ineffective. Heat may cause the tick to release pathogens into the bite site, heightening infection risk, and can burn the skin. Safe removal involves tweezers grasping the tick near the skin for intact extraction, reducing complications like Lyme disease or Rocky Mountain spotted fever transmission.

Choice C reason: Grasping the tick close to the skin with fine-tipped tweezers is the standard method. This ensures complete removal, including mouthparts, minimizing infection risk from pathogens like Borrelia burgdorferi, which causes Lyme disease. The technique prevents tissue damage and pathogen spread, promoting safe extraction and reducing complications from tick-borne illnesses.

Choice D reason: Using a twisting motion risks breaking the tick’s mouthparts, leaving them embedded, which increases infection risk and complicates removal. A steady, upward pull without twisting is recommended to extract the tick fully, preventing transmission of diseases like Lyme disease or babesiosis, ensuring effective and safe tick removal.
