Cross-System Adverse Effects - National Physical Therapy Examination NPTE

1. What is the immediate first action when autonomic dysreflexia is suspected during therapy?

   Sit the patient upright and lower legs. This action promotes venous pooling in the lower extremities to rapidly reduce hypertensive crisis in autonomic dysreflexia.

2. What is the most likely adverse effect of aggressive chest percussion in a patient on anticoagulants?

   Bleeding or chest wall hematoma. Anticoagulation impairs clotting, making tissues prone to hemorrhage from mechanical trauma during percussion therapy.

3. What is the primary complication risk of electrical stimulation in a patient with an implanted pacemaker?

   Device interference causing dysrhythmia. Electrical fields from stimulation can interfere with pacemaker sensing or pacing functions, triggering inappropriate cardiac responses.

4. Which adverse effect is most likely if a patient with diabetes is exercised without monitoring timing of insulin and meals?

   Hypoglycemia (sweating, tremor, confusion). Exercise increases glucose utilization, which, combined with insulin, can exceed available blood sugar without proper timing.

5. Which vital-sign response is abnormal and suggests cardiovascular compromise during light exercise?

   Decreasing systolic blood pressure with increasing workload. This response indicates failing cardiac output adaptation to exercise demands, often due to underlying heart disease or deconditioning.

6. What is the key adverse effect of compression garments that are too tight in peripheral arterial disease?

   Worsened limb ischemia and increased pain. Excessive compression restricts arterial inflow, exacerbating tissue hypoxia in limbs with already compromised perfusion.

7. Which complication is most associated with excessive oxygen delivery in a chronic $CO_2$ retainer (severe COPD)?

   Worsening hypercapnia and decreased respiratory drive. High oxygen suppresses hypoxic drive in COPD patients, leading to hypoventilation and further $CO_2$ retention.

8. Which adverse effect most suggests a latex allergy triggered by therapy equipment or gloves?

   Urticaria or wheezing shortly after exposure. Latex proteins trigger IgE-mediated hypersensitivity, manifesting as immediate allergic reactions upon contact in sensitized individuals.

9. What adverse effect can occur if a patient with osteoporosis receives high-velocity spinal manipulation?

   Vertebral compression fracture. High-velocity forces exceed the brittle bone's tolerance in osteoporosis, risking collapse of weakened vertebral bodies.

10. Which adverse effect can occur if traction is used in a patient with spinal malignancy?

    Pathologic fracture or spinal instability worsening. Traction forces can destabilize metastatic lesions, increasing fracture risk in structurally compromised vertebrae.

11. Which symptom during therapy most suggests pulmonary embolism as a complication of another condition?

    Sudden dyspnea with pleuritic chest pain. These symptoms reflect acute pulmonary vascular occlusion, often from emboli dislodged during activity in at-risk patients.

12. Identify the adverse effect of inappropriate high-intensity exercise in a patient with acute DVT.

    Pulmonary embolism from clot dislodgement. High-intensity activity can mobilize thrombi from deep veins, leading to embolization in pulmonary arteries.

13. Identify the most likely adverse effect of aggressive airway suctioning in a medically fragile patient.

    Vagal response causing bradycardia. Aggressive suctioning stimulates vagal nerve endings in the airways, leading to parasympathetic overactivity and heart rate slowing.

14. Which complication is most associated with prolonged immobility and inadequate repositioning in bed?

    Pressure injury (decubitus ulcer). Sustained pressure on bony prominences impairs skin perfusion, leading to tissue ischemia and necrosis in immobile patients.

15. Which adverse effect most strongly indicates autonomic dysreflexia during intervention in a patient with SCI above $T_6$?

    Severe hypertension with pounding headache. This symptom arises from unopposed sympathetic response below the spinal cord injury level triggered by noxious stimuli, requiring immediate intervention.

16. Identify the adverse effect of heat modality over an area with impaired sensation (neuropathy).

    Thermal burn due to reduced protective feedback. Impaired sensation prevents detection of excessive heat, leading to prolonged exposure and tissue damage.

17. What adverse effect is most associated with rapid position change from supine to standing in older adults?

    Orthostatic hypotension with dizziness or syncope. Rapid postural changes impair baroreceptor reflexes in older adults, leading to inadequate compensatory vasoconstriction and cerebral hypoperfusion.

18. What complication is most associated with prolonged Trendelenburg positioning in intracranial pathology?

    Increased intracranial pressure. Trendelenburg positioning increases cerebral venous pressure, exacerbating edema in patients with elevated intracranial pressure.

19. Which complication is most associated with aggressive stretching in a patient with hemophilia?

    Hemarthrosis or intramuscular bleeding. Hemophilia impairs clotting factors, making joints and muscles susceptible to hemorrhage from mechanical stress during stretching.

20. Which complication is most associated with prolonged supine positioning in acute heart failure?

    Pulmonary edema with worsening dyspnea. Prolonged supine positioning causes fluid redistribution from lower body to pulmonary circulation, exacerbating congestion in heart failure patients.

21. What is the most likely complication of cryotherapy applied too long to superficial nerves?

    Cold-induced nerve injury (neuropraxia). Prolonged cold exposure can cause temporary conduction block in superficial nerves due to slowed axonal transmission.

22. Which adverse effect is most associated with ultrasound over an epiphyseal plate in a child?

    Potential growth plate damage. Ultrasound energy may disrupt actively growing epiphyseal cartilage, potentially impairing bone development in pediatric patients.

23. Identify the most concerning sign of exercise intolerance suggesting myocardial ischemia during rehab.

    Chest pressure radiating to jaw or left arm. These symptoms indicate reduced coronary perfusion during exercise, signaling potential acute coronary syndrome requiring immediate cessation.

24. Which complication can occur if a patient performs Valsalva during resisted exercise?

    Marked blood pressure rise and arrhythmia risk. Valsalva maneuver increases intrathoracic pressure, reducing venous return and cardiac output while elevating afterload on the heart.
