A nurse is teaching a group of middle adult clients about osteoporosis. Which of the following risk factors should the nurse include?

Choice A rationale:
(Potassium level) Lovastatin is a medication used to treat high cholesterol levels. While potassium levels are important to monitor for certain conditions, they are not directly related to the initiation of lovastatin therapy. Therefore, this is not the correct choice for diagnostic testing before starting the medication.
Choice B rationale:
(Hemoglobin level) Hemoglobin levels are important to assess for anemia or other blood disorders. However, they are not specifically required before starting lovastatin therapy. Therefore, this is not the correct choice for diagnostic testing before starting the medication.
Choice C rationale:
(Kidney function tests) While kidney function tests are essential for many medications to ensure proper excretion and avoid toxicity, they are not directly related to the initiation of lovastatin therapy. Therefore, this is not the correct choice for diagnostic testing before starting the medication.
Choice D rationale:
(Liver function tests) Liver function tests are crucial before starting lovastatin therapy. Lovastatin is metabolized in the liver, and it can potentially cause liver damage or abnormalities in liver enzymes. Monitoring liver function helps detect any pre-existing liver conditions and ensures the safe use of the medication. Therefore, this is the correct choice for diagnostic testing before starting the medication.

Choice A rationale:

Using fingers to remove loose tissue is not an appropriate action for the nurse to take when providing hydrotherapy for a burn wound. This action can cause further trauma to the wound and increase the risk of infection.

Choice B rationale:

Opening small blisters to expose air is contraindicated in burn wound management. The blister roof provides a natural barrier against infection, and puncturing them increases the risk of infection and delays the healing process.

Choice C rationale:

The correct answer is to wash the burn with a mild soap. Cleaning the burn wound with mild soap and water helps remove debris and minimize the risk of infection without causing additional damage.

Choice D rationale:

Applying wet-to-dry dressings is an outdated and inappropriate practice for burn wound care. Wet-to-dry dressings can be painful, disrupt wound healing, and increase the risk of infection. Modern burn wound care focuses on maintaining a moist environment to support optimal healing.
