What drug enhances the output of respiratory tract fluid by reducing the adhesiveness and surface tension of the fluid which facilitates the removal of viscous mucus?
Guaifenesin.
Dextromethorphan.
Acetylcysteine.
Flunisolide.
The Correct Answer is A
Choice A rationale
Guaifenesin is an expectorant that increases the output of respiratory tract fluid by reducing the adhesiveness and surface tension of the mucus, facilitating the removal of viscous mucus.
Choice B rationale
Dextromethorphan is a cough suppressant that works on the cough center in the brain to reduce the urge to cough. It does not enhance the output of respiratory tract fluid.
Choice C rationale
Acetylcysteine is a mucolytic that breaks down the chemical structure of mucus molecules, making the mucus less viscous, but it does not enhance the output of respiratory tract fluid by reducing adhesiveness.
Choice D rationale
Flunisolide is an inhaled corticosteroid used to reduce inflammation in the airways. It does not enhance the output of respiratory tract fluid.

Correct Answer is C
Explanation
Choice A rationale
Calcium and magnesium imbalances are less likely to influence Digoxin's effects compared to potassium and magnesium.
Choice B rationale
While chloride levels are important, potassium is more critical due to its significant impact on Digoxin’s action.
Choice C rationale
Correct, potassium and magnesium levels are crucial as imbalances can potentiate Digoxin toxicity or reduce its efficacy.
Choice D rationale
Sodium and calcium imbalances are less directly related to Digoxin efficacy compared to potassium and magnesium.
Correct Answer is C
Explanation
Choice A rationale
Exhibiting the ability to provide self-care may not be realistic for a patient with advanced Alzheimer’s disease. Cognitive decline may impair their ability to perform daily activities independently, necessitating assistance from caregivers.
Choice B rationale
Improving memory for recent events is unlikely in advanced Alzheimer’s disease, as the condition typically involves progressive memory loss and cognitive decline. New medications may help manage symptoms, but reversing memory loss is not a realistic goal.
Choice C rationale
Receiving appropriate assistance for care needs is a realistic and achievable goal for patients with advanced Alzheimer’s disease. As the disease progresses, patients will require increasing levels of support to ensure their safety and well-being.
Choice D rationale
Demonstrating improved cognitive function is unlikely in advanced Alzheimer’s disease. While medications may help manage symptoms, the progressive nature of the disease means that cognitive decline will continue, and improvement is not a realistic expectation.
