The metal toxin which produces increased bone density and inhibition of fracture healing is arsenic.

The EKG technician is performing a standard 12-lead EKG for a patient. The technician should identify that which of the following information is recorded by Lead I? 

How many PVCs in a row is considered pathological?

Client Profile: Mrs. Vance Detail Description Age & Sex 55-year-old female Family Status Mother of three children, all under 10 years old. Past Exercise History Was an experienced strength trainer earlier in life, but has not lifted weights in two years. Enjoys running when actively training. Current Exercise Walks for 20 minutes two days per week with friends. No current intense cardio. Health History No history of cardiovascular disease (CVD). No history of surgery. Current Symptoms Reports shortness of breath (dyspnea) when ascending stairs or walking for prolonged periods. Vitals & Anthropometrics Resting HR: 74 bpm Blood Pressure: 115/75mmHg Weight: 250 lbs Height: 4 ft 5 in Client Goals Gain strength and lose weight. Student Tasks and Prescriptive Requirements Use the provided client data to complete the following tasks. Remember to show all calculations and reasoning, referencing relevant ACSM Guidelines where appropriate. Task 1: Health Risk Assessment and Stratification (ACSM Pre-screening) Calculate Body Mass Index (BMI):   Apply the ACSM Pre-screening Algorithm: Identify and document the number of risk factors Mrs. Vance presents (or negative risk factors). Justify your selection for each factor. Determine the presence of signs/symptoms of cardiovascular disease, metabolic disease, or renal disease. Justify your finding. Based on the ACSM algorithm, categorize Mrs. Vance’s Current Exercise Status (Regularly Exercising or Not) and Risk Classification (Lowest, Moderate, or High). Determine the required Medical Clearance (Yes or No) needed before beginning: A Light-to-Moderate Intensity exercise program. A Vigorous Intensity exercise program. Task 2: Principles of Exercise Prescription (FITT-VP) Develop a comprehensive initial 4-week exercise prescription plan based on the FITT-VP principle. Cardiorespiratory Endurance Prescription: Frequency: Recommend the number of days per week. Intensity: Recommend a target HR range using the HRR method (Karvonen) for Moderate intensity Time (Duration): Recommend the total minutes per session. Type: Recommend a specific type of cardio that aligns with her goals and current limitations. Progression: Resistance Training Prescription: Focus: Design a program emphasizing strength gain and supporting weight loss goals, considering her past experience but current deconditioning. Frequency: Recommend the number of days per week. Type/Mode: Recommend a type of training (e.g., bodyweight, free weights, machines) and provide three specific exercises. Volume (Sets & Reps): Recommend appropriate sets and repetitions to maximize strength gains while minimizing injury risk for a beginner. Rest: Recommend appropriate rest intervals between sets.

What are the ABSOLUTE contraindications to clinical exercise testing?

Identify these symptoms of Angina as Typical (Definite) or Atypical. Chest discomfort that lacks one of the mentioned characteristics.

The magnitude of ischemia caused by a coronary lesion is NOT generally in direct proportion to Degree of ST segment depression, Number of ECG leads involved, and duration of ST-segment depression in recovery.

Significant ST-segment depression occurring only in recovery likely represents a true positive response and should be considered an important diagnostic finding. (During clinical exercise testing interpretations.)

What are the indications for terminating a symptom-limited maximal exercise test?

ST-segment depression localizes ischemia to a specific area of myocardium. (During clinical exercise testing interpretations.)
