Correct Answer: D

Rationale: A trimalleolar fracture is characterized by fractures involving the lateral malleolus (distal fibula), medial malleolus (distal tibia), and the posterior tubercle of the distal tibia. This fracture pattern results in instability of the ankle joint and is often associated with widening of the ankle mortise on X-ray. The deformity and swelling seen in this patient are indicative of a trimalleolar fracture and are typically caused by a high-energy injury, such as a forceful twisting motion. Treatment for trimalleolar fractures often involves surgical intervention to stabilize the ankle joint and restore normal function.

Correct Answer: A

Rationale: The patient's presentation of recurrent episodes of sudden, severe vertigo lasting hours, along with nausea, vomiting, nystagmus, and unilateral weakness on vestibular function tests, is most consistent with vestibular neuritis. Vestibular neuritis is an inflammatory disorder of the vestibular nerve, typically viral in origin, leading to acute onset of vertigo. Patients often experience severe vertigo, imbalance, nausea, and vomiting, along with characteristic nystagmus. Unilateral weakness on vestibular function testing supports the diagnosis of vestibular neuritis, as it indicates dysfunction of one vestibular organ. Benign paroxysmal positional vertigo (BPPV) typically presents with brief episodes of vertigo triggered by changes in head position without associated unilateral vestibular weakness. Ménière's disease is characterized by recurrent episodes of vertigo associated with fluctuating hearing loss, tinnitus, and aural fullness, and

Correct Answer: C

Rationale: The most likely causative agent in this scenario is Borrelia burgdorferi, which is the bacterium responsible for causing Lyme disease. The classic presentation of Lyme disease includes fever, malaise, and a skin lesion resembling a "bull's eye" rash, known as erythema migrans. This rash typically appears at the site of a tick bite. If left untreated, Lyme disease can progress to involve multiple organ systems and lead to more severe complications. Plasmodium falciparum is the causative agent of malaria, which typically presents with symptoms such as fever, chills, and fatigue, but it does not cause a "bull's eye" rash. Trypanosoma cruzi is the parasite responsible for Chagas disease, which presents with symptoms such as fever, swelling at the site of entry (typically the bite wound), and enlarged lymph nodes, but it does not

Correct Answer: C

Rationale: Preoperative nursing intervention that is essential for preparing a patient with a history of coronary artery disease for coronary artery bypass graft (CABG) surgery is assisting the patient with deep breathing and coughing exercises. These exercises are crucial to prevent postoperative complications such as atelectasis and pneumonia, which are common risks after surgery. Deep breathing exercises help to expand the lungs and improve ventilation, while coughing exercises help to clear secretions and prevent respiratory complications. By assisting the patient with these exercises preoperatively, the nurse can help optimize the patient's respiratory function and decrease the risk of complications during and after surgery. Administering aspirin, providing education about pain management, and obtaining informed consent are also important aspects of preoperative care, but assisting with deep breathing and coughing exercises is particularly essential for patients undergoing CABG surgery due to the increased risk of respiratory complications in this population.

Correct Answer: B

Rationale: The nurse should prioritize cleansing the insertion site with an alcohol-based antiseptic solution to maintain procedural asepsis during a peripherally inserted central catheter (PICC) insertion. Proper skin preparation is essential in reducing the risk of introducing pathogens into the patient's bloodstream during the insertion process. Alcohol-based antiseptic solutions are effective in reducing the number of microorganisms on the skin surface. Wearing sterile gloves and following other sterile techniques are also crucial, but preparing the insertion site with the antiseptic solution is the initial step in maintaining asepsis during the procedure.
