The nurse informs a client they need to stop taking loratadine four days before their scheduled allergy testing. What is the indication for stopping loratadine?
Loratadine can interfere with the accuracy of the test.
Loratadine can cause increased sensitivity to allergens.
Loratadine can cause hypotension during the allergy test.
Loratadine can cause an allergic reaction during the test.
The Correct Answer is A
A. Loratadine can interfere with the accuracy of the test: Loratadine is a second-generation antihistamine that blocks H1 receptors. Continuing the medication can suppress allergic responses, leading to false-negative results during allergy testing, which is why it must be discontinued several days beforehand.
B. Loratadine can cause increased sensitivity to allergens: Loratadine does not increase sensitivity to allergens. Its mechanism involves reducing the body’s allergic response, not enhancing it, so this is not a reason to stop the medication before testing.
C. Loratadine can cause hypotension during the allergy test: Loratadine does not significantly affect blood pressure. Hypotension is not a known effect of loratadine during allergy testing, so this is not a valid reason for discontinuation.
D. Loratadine can cause an allergic reaction during the test: Loratadine itself is unlikely to trigger an allergic reaction. The purpose of stopping the drug is to prevent interference with test results, not to prevent a reaction caused by the medication.

Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"B"}
Explanation
• Sit down after taking nitroglycerin: Nitroglycerin causes rapid vasodilation, which can lead to a sudden drop in blood pressure shortly after administration. Sitting or lying down helps reduce the risk of dizziness, syncope, and falls during this period. This instruction is especially important because sublingual nitroglycerin acts quickly.
• Hypotension: Nitroglycerin relaxes vascular smooth muscle, leading to decreased preload and afterload. This vasodilatory effect can cause orthostatic or systemic hypotension, particularly with the first dose. Monitoring and education focus on preventing complications related to low blood pressure, such as lightheadedness or fainting.
Correct Answer is ["B","C","D"]
Explanation
A. "This inhaled corticosteroid should be used to treat an acute asthma attack.": Inhaled corticosteroids are maintenance medications used for long-term control of asthma. They are not rescue medications and will not provide immediate relief during an acute asthma attack.
B. "You may notice dry mouth and throat irritation while using this medication.": Dry mouth and throat irritation are common local side effects of inhaled corticosteroids due to their anti-inflammatory action on airway mucosa, making this important to include in patient education.
C. "Pay special attention to your dental hygiene while prescribed this medication.": Good oral hygiene is crucial because inhaled corticosteroids can increase the risk of oral candidiasis and other oral infections. Educating the client on brushing, flossing, and routine dental care helps reduce these risks.
D. "After administration of the medication, rinse your mouth with water and spit.": Rinsing the mouth after inhalation helps remove residual medication, reducing the risk of oral fungal infections and irritation, which is an essential preventive measure.
E. "White patches in your mouth are expected when you take this medication.": White patches, or oral thrush, are not expected but are a potential adverse effect. The client should be advised to report these signs rather than assume they are normal.
