An older client who has type 2 diabetes mellitus (DM) and a history of heart failure (HF) tells the home health nurse that his daughter brought him melatonin to help with sleeping problems. Which information should the nurse provide to the client? Select all that apply.

A. Insomnia may occur while taking the medication: St. John's wort can increase central nervous system stimulation, leading to side effects like insomnia, restlessness, and anxiety. Educating the client that sleep disturbances may occur is appropriate and consistent with known herb effects.

B. Another form of contraception is not needed: St. John's wort can induce cytochrome P450 enzymes, leading to faster metabolism and reduced effectiveness of hormonal contraceptives like birth control pills. Clients must be advised to use an additional non-hormonal contraceptive method to prevent unintended pregnancy.

C. Hard candy can be used for a dry mouth: Dry mouth is a recognized side effect of St. John's wort. Sucking on hard candy, increasing oral hydration, or chewing sugarless gum are appropriate and effective ways to manage this discomfort.

D. Sensitivity to the sun can develop: Photosensitivity is a well-documented adverse effect of St. John's wort. Clients should be instructed to use sunscreen, wear protective clothing, and limit sun exposure to prevent sunburns or skin reactions.

Understanding:

• "If this treatment plan does not work, there are other drugs and combinations of drugs that I can get from my doctor to manage my asthma."
• "Even with asthma, I can maintain normal activity levels."
• "I should keep track of my peak expiratory flow to see how well I am managing my asthma."
• "I can decrease my risk of asthma attacks if I reduce my exposure to allergens in my home."

No Understanding:

• "The inhaled fluticasone that I was prescribed carries just as much risk as an oral steroid."
• "I should discontinue using albuterol after I fill my prescription for fluticasone."

Rationale:

• "The inhaled fluticasone that I was prescribed carries just as much risk as an oral steroid." This shows no understanding because inhaled corticosteroids like fluticasone have much lower systemic absorption compared to oral steroids, minimizing systemic side effects while still controlling airway inflammation locally.
• "If this treatment plan does not work, there are other drugs and combinations of drugs that I can get from my doctor to manage my asthma." This shows understanding because asthma management follows a stepwise approach. Treatment is escalated if control is not achieved, using combinations like LABAs, leukotriene modifiers, or biologics.
• "Even with asthma, I can maintain normal activity levels." This shows understanding because the goal of asthma management is to control symptoms so that clients can perform normal daily activities without limitation, including exercise and work.
• "I should keep track of my peak expiratory flow to see how well I am managing my asthma." This shows understanding because peak flow monitoring helps detect early decreases in lung function, guiding self-management decisions and the need for treatment adjustments.
• "I can decrease my risk of asthma attacks if I reduce my exposure to allergens in my home." This shows understanding because environmental control measures, such as reducing dust mites, pet dander, and mold, are key strategies to lower asthma exacerbation risk and improve long-term control.
• "I should discontinue using albuterol after I fill my prescription for fluticasone." This shows no understanding because albuterol, a rescue inhaler, should still be kept available for acute symptom relief even when a daily controller medication like fluticasone is added.
