A physical therapist observes the gait of a patient rehabilitating from a traumatic brain injury. The patient has significant spasticity in the lower extremities and demonstrates a scissoring gait pattern. The MOST likely cause of the gait deviation is increased tone in the:

Correct Answer: A

Rationale: The correct answer is A) hip adductors. In a scissoring gait pattern, the legs cross midline due to increased tone in the hip adductors, causing them to pull the legs towards each other during walking. This results in a narrow-based, stiff-legged gait characteristic of spasticity. Option B) hip abductors would actually help to counteract the adduction and prevent the legs from crossing over excessively. Option C) knee flexors and Option D) ankle dorsiflexors are not primarily responsible for the scissoring gait seen in this patient. Educationally, understanding gait deviations related to spasticity is crucial for healthcare professionals like physical therapists to effectively assess and treat patients with neurological conditions. Recognizing the specific muscle groups involved in abnormal gait patterns can guide interventions aimed at improving mobility and quality of life for patients undergoing rehabilitation.

Correct Answer: B

Rationale: In this case, the most appropriate intervention to improve endurance in a patient with multiple sclerosis (MS) experiencing fatigue is option B) Aquatic therapy. Aquatic therapy is a highly effective intervention for individuals with MS as it provides a supportive environment that reduces the impact of gravity, making movements easier and less fatiguing. The buoyancy of water helps to support the patient's body weight, allowing for increased mobility and endurance building without excessive strain on the muscles and joints. High-intensity interval training (option A) may not be suitable for a patient with MS experiencing fatigue, as it can be too intense and may exacerbate symptoms. Progressive resistance training (option C) focuses more on strength building rather than endurance, which may not directly address the patient's fatigue concerns. Treadmill walking at 85% HR max (option D) can be too strenuous for a patient experiencing fatigue and may not be well-tolerated. In an educational context, understanding the specific needs and limitations of patients with MS is crucial for healthcare professionals. Aquatic therapy is a valuable tool in rehabilitation for individuals with MS, as it allows for safe and effective endurance training while minimizing the risk of injury or exacerbating symptoms. Educating therapists on the benefits of aquatic therapy and its tailored approach for patients with MS can significantly improve outcomes and quality of care.

Correct Answer: C

Rationale: In a cardiovascular assessment, the presence of jugular vein distension (JVD) in a patient sitting at a 45-degree angle typically indicates heart failure. When the heart fails to effectively pump blood forward, increased pressure builds up in the venous system, leading to JVD. This finding is due to the back-up of blood in the venous system, causing the jugular veins to become visibly distended. Option A: Jugular vein distension at 45 degrees is not a normal finding. It suggests underlying cardiovascular issues rather than being a typical response to positioning. Option B: Dehydration would not directly cause jugular vein distension. Dehydration might lead to decreased venous return, but it would not manifest as visible JVD in this scenario. Option D: While a pulmonary embolism can cause strain on the heart and lead to right-sided heart failure, jugular vein distension alone is more strongly indicative of heart failure in this context. Educationally, understanding the significance of JVD in cardiovascular assessment is crucial for nurses to recognize early signs of heart failure and provide timely interventions. Recognizing this clinical manifestation can guide appropriate nursing interventions and facilitate prompt communication with healthcare providers for further evaluation and management.

Correct Answer: D

Rationale: In assessing a patient's carotid arteries, the most appropriate technique is to palpate one carotid artery at a time. This is the correct answer because palpating one artery at a time allows the nurse to assess for any abnormalities such as pulsations, thrills, or bruits without compromising blood flow to the brain. Palpation should be gentle to avoid excessive pressure on the carotid sinus, which could lead to a dangerous drop in blood pressure. Option A, auscultating for bruits using the diaphragm of the stethoscope, is incorrect as bruits are typically auscultated over the carotid arteries, not palpated. Palpating both carotid arteries simultaneously (Option B) can obstruct blood flow and is not recommended. Option C, percussing the carotid arteries for tenderness, is not a standard or appropriate technique for assessing carotid arteries. Educationally, it's important for nurses to understand the proper techniques for assessing vital signs like carotid artery palpation to ensure accurate and safe patient evaluation. Palpating both carotid arteries simultaneously can lead to inaccurate assessments, highlighting the importance of following correct procedures for patient safety and accurate data collection.

Correct Answer: B

Rationale: In a musculoskeletal assessment, the presence of swelling and deformity suggests a possible fracture. Swelling occurs due to soft tissue inflammation from the injury, and deformity can indicate a disruption in the normal anatomical alignment of bones, characteristic of a fracture. This finding requires immediate attention to prevent further damage and ensure proper treatment. Option A, symmetrical range of motion, is incorrect because it refers to the ability to move joints equally on both sides of the body and does not specifically indicate a fracture. Option C, crepitus in the joint (a grating or grinding sensation), is more indicative of joint conditions like osteoarthritis rather than a fracture. Option D, warmth and redness over the joint, typically suggest inflammation, infection, or inflammation, which are not specific to fractures. Educationally, understanding these signs in a musculoskeletal assessment is crucial for healthcare professionals to accurately identify and manage fractures, ensuring appropriate care and promoting patient recovery and well-being.
