A nurse is providing discharge teaching to the parent of a child who is prescribed diphenhydramine 25 mg elixir every 4 hr as needed. The amount available is diphenhydramine elixir 12.5 mg/5 mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["10"]
To determine the mL of diphenhydramine elixir to administer per dose, we need to calculate the dose based on the prescribed amount and the concentration of the elixir.
Given:
Prescribed dose: 25 mg Concentration of elixir: 12.5 mg/5 mL
We can set up a proportion to find the equivalent mL for the prescribed dose: 25 mg / x mL = 12.5 mg / 5 mL
Cross-multiplying and solving for x, we get:
25 mg * 5 mL = 12.5 mg * x mL 125 mg = 12.5 mg * x mL
125 mg / 12.5 mg = x mL 10 mL = x mL
Therefore, the nurse should administer 10 mL of diphenhydramine elixir per dose.

Correct Answer is A
Explanation
Nasal glucocorticoids, also known as intranasal corticosteroids, are considered the most effective and recommended first-line treatment for nasal congestion caused by allergic rhinitis or non-allergic rhinitis. They work by reducing inflammation in the nasal passages, relieving congestion, and improving other symptoms such as itching, sneezing, and runny nose.
Leukotriene modifiers, decongestants, and antihistamines can also be used to manage nasal congestion, but they are generally considered second-line options or adjunct therapies.
Decongestants provide temporary relief by constricting blood vessels in the nasal passages, while antihistamines help with symptoms related to allergies. Leukotriene modifiers are primarily used for managing asthma and are not typically the first choice for nasal congestion alone.
Correct Answer is A
Explanation
Inhaled fluticasone (Flovent) is a corticosteroid medication that is commonly used in the treatment of asthma. It works by reducing inflammation in the airway, which is a key component of asthma. By decreasing inflammation, it helps to prevent and control asthma symptoms, such as wheezing, coughing, and shortness of breath.
The other options mentioned are incorrect:
B. Relieves symptoms of an acute asthma attack: Inhaled fluticasone is not intended for immediate relief during an acute asthma attack. It is a long-term control medication used to manage and prevent asthma symptoms.
C. Causes immediate bronchodilation: Fluticasone does not cause immediate bronchodilation, which refers to the widening of the airways to improve breathing. Bronchodilation is typically achieved with short-acting beta-agonist medications, such as albuterol.
D. Reduces blood pressure and heart rate: Fluticasone is not known to have a direct effect on blood pressure or heart rate. Its primary action is to reduce inflammation in the airway for the management of asthma.
