A nurse is educating an older adult client at risk for osteoporosis on starting a regular physical activity program. Which type of activity should the nurse recommend?
Walking briskly
Riding a bicycle
Performing isometric exercises
Engaging in high-impact aerobics
The Correct Answer is A
Choice A rationale
Walking briskly is a weight-bearing exercise that is essential for maintaining bone mass, which can help to prevent osteoporosis. Regular weight-bearing exercise, such as a 20-30-minute aerobic exercise, 3 times a week, is recommended for older adults at risk for osteoporosis.
Choice B rationale
Riding a bicycle is a non-weight-bearing exercise. While it can contribute to overall fitness and health, it does not provide the same benefits for bone health as weight-bearing exercises like walking.
Choice C rationale
Performing isometric exercises can help to strengthen muscles, but these exercises do not have the same impact on bone health as weight-bearing exercises.
Choice D rationale
Engaging in high-impact aerobics can be beneficial for bone health, but it may not be suitable for an older adult at risk for osteoporosis due to the increased risk of injury.

Correct Answer is ["8"]
Explanation
Step 1 is: Calculate the total units of heparin in the bag, which is 25,000 units.
Step 2 is: Divide the total units by the total volume to find the units per mL, which is (25,000 units ÷ 250 mL) = 100 units/mL.
Step 3 is: Divide the desired units per hour by the units per mL to find the mL/hr, which is (800 units/hr ÷ 100 units/mL) = 8 mL/hr. So, the infusion pump rate should be set at 8 mL/hr.
Correct Answer is B
Explanation
Choice A rationale: Using a resuscitation bag with 80% oxygen prior to the procedure is inappropriate. While pre-oxygenation is important before suctioning to prevent hypoxia, the oxygen concentration should be 100%, not 80%. Normal oxygen saturation levels are 95% to 100%. Pre-oxygenating with 100% oxygen ensures the patient maintains adequate oxygenation during the brief suctioning period. Using 80% oxygen does not fully optimize oxygen reserves for this purpose.
Choice B rationale: Selecting a suction catheter that is half the size of the tracheostomy lumen is appropriate. This size prevents excessive occlusion of the airway, ensuring adequate airflow during suctioning. The correct catheter size minimizes trauma to the tracheal mucosa and prevents hypoxia. The catheter should not exceed 50% of the tracheostomy diameter to maintain proper airway function, making this the correct action for safe and effective suctioning.
Choice C rationale
Placing the end of the suction catheter in water-soluble lubricant is not recommended. This could introduce bacteria into the airway and increase the risk of infection.
Choice D rationale
Adjusting the wall suction apparatus to a pressure of 170 mm Hg is not correct. The recommended suction pressure for adults is usually between 80 and 120 mm Hg. Suctioning at too high a pressure can cause trauma to the airway.
