Vitamin D plays an important part in the absorption of calcium by the body.
Where is vitamin D activated into a form that promotes calcium absorption?
Small intestine.
Vitamin D is not activated into another form.
Kidneys.
Large intestine.
The Correct Answer is C
Choice A rationale
The small intestine is where nutrients are absorbed, but it is not where vitamin D is activated. Vitamin D is first converted in the liver and then activated in the kidneys to promote calcium absorption.
Choice B rationale
This is incorrect because vitamin D is activated into a form that promotes calcium absorption. The active form is crucial for maintaining calcium and phosphate levels in the blood.
Choice C rationale
The kidneys play a significant role in converting vitamin D to its active form, calcitriol. This activated form is essential for the absorption of calcium in the intestines.
Choice D rationale
The large intestine is involved in water absorption and waste formation but not in the activation of vitamin D. The activation process primarily occurs in the kidneys and liver. .

Correct Answer is C
Explanation
Choice A rationale
Reassuring the client without addressing the persistent cough would not be appropriate as it may signal a need for a different medication. The ACE inhibitor captopril can cause a bothersome, persistent cough in some patients due to increased bradykinin levels.
Choice B rationale
Instructing the patient to stop the medication immediately is not advised without consulting the healthcare provider. While the cough is a known side effect, stopping the medication abruptly may lead to unmanaged hypertension.
Choice C rationale
Scheduling an appointment with the provider to discuss changing to an angiotensin II receptor blocker (ARB) is appropriate. ARBs do not typically cause a persistent cough, making them a suitable alternative for patients who experience this side effect with ACE inhibitors.
Choice D rationale
Instructing the patient to go to the emergency room immediately is unnecessary as the persistent cough is a common side effect of ACE inhibitors and not an emergency situation. Emergency action is warranted for symptoms of angioedema, such as swelling of the face or throat.
Correct Answer is A
Explanation
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.
