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 ["10ml"]
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 C
Explanation
Status asthmaticus is a severe and potentially life-threatening asthma exacerbation that does not respond well to usual treatment measures. The primary goal in managing status asthmaticus is to relieve the bronchospasm and improve airflow. Short-acting 62-agonists, such as albuterol, are bronchodilators that work quickly to relax the smooth muscles of the airways, providing immediate relief of bronchospasm.
While determining the cause of the acute exacerbation and obtaining a peak flow reading are important aspects of asthma management, in the case of status asthmaticus, the immediate priority is to administer a bronchodilator to alleviate the severe symptoms and improve the child's breathing. Once the acute symptoms are addressed, further assessment and interventions can be carried out to identify the cause and monitor the child's condition.
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.
