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 D
Explanation
Acetylcysteine has a strong and distinct odor, often described as a sulfur-like smell. It is important for the adolescent to be aware of this characteristic odor so that they do not become alarmed or concerned when they encounter it.
The other options mentioned are incorrect:
A. It is necessary to monitor your serum electrolyte levels: Monitoring serum electrolyte levels is not typically required with oral acetylcysteine therapy. However, it is important to follow the healthcare provider's instructions regarding monitoring and follow-up appointments.
B. "You should avoid eating eggs": There is no specific dietary restriction or need to avoid eating eggs while taking oral acetylcysteine. However, it is always advisable to follow a balanced and healthy diet.
C. "Your mouth will become dry!": Dry mouth is not a common side effect of oral acetylcysteine. Side effects may vary from person to person, but dry mouth is not typically associated with this medication.
Correct Answer is B
Explanation
Codeine is an opioid medication that can cause drowsiness and dizziness. Changing positions quickly, especially from lying down to standing up, can increase the risk of falls or accidents.
Instructing the client to change positions slowly helps prevent orthostatic hypotension (a drop in blood pressure upon standing) and reduces the risk of falls.
The other options listed are not appropriate instructions for a client taking codeine:
A. "You should expect to experience diarrhea while taking this medication." While constipation is a common side effect of opioids, diarrhea is not typically associated with codeine use. Therefore, there is no need to expect or warn about diarrhea as an anticipated effect of taking codeine.
C. "You should limit alcohol intake to 12 ounces daily." Mixing alcohol with codeine can have harmful effects, such as increased sedation and respiratory depression. However, it is generally recommended to avoid alcohol completely while taking codeine, rather than setting a specific limit of 12 ounces daily.
D. "You should take the medication on an empty stomach to prevent nausea." Taking codeine with or without food can vary depending on individual factors and the specific instructions provided by the healthcare provider. However, taking codeine on an empty stomach does not necessarily prevent nausea. In fact, taking it with food may help reduce stomach upset for some individuals. It is best to follow the specific instructions provided by the healthcare provider regarding the timing of codeine administration with or without food.
