You’re talking with Liliana before her release from the hospital. Which of her statements indicates the need for further patient education
Basing this answer on the patient with a tibia fracture and open reduction, we can confirm that Liliana indicating that she should only take calcium supplements would require further patient education.
Why is this statement wrong?Liliana will be recovering from a post-op condition. This means that she will be at risk of developing an infection. This will most likely require preemptive antibiotic supplements to reduce the likelihood of infection. This may be coupled with pain medication as well.
Therefore, since Liliana will require more medications and supplements than calcium, her statement shows the need for further patient education.

The fungus Botrytis is known to cause rot in fruit and decrease the harvest. In an effort to limit the damage, some agriculturalists spray the soil of orchards with fungicides. The effect of fungicides is not specific for Botrytis and kills most fungi in the soil. In a short answer, predict what would happen to the yield of grapes following fumigation and explain the rationale for your prediction.
The yield of grapes following fumigation will be decreased as a result of the effect of fungicides not being specific.
What is Mycorrhizal fungi?This is a type of fungi which is present in the soil and helps plant to absorb more nutrients and water.
Tbis fungi also increases microbial activity which are needed for optimal growth of of the grape. Application of the fungicide will kill these beneficial fungi thereby leading to a decrease in the yield.
