A client is ordered digoxin 0.25mg po. daily. On hand is a liquid in a dropper bottle labeled 500mcg/10mL. How many milliliters will be administered?
The Correct Answer is ["5"]
Given:
Desired dose: Digoxin 0.25 mg PO daily
Available concentration: Digoxin 500 mcg/10 mL
To find:
Volume to administer (in mL)
Step 1: Convert desired dose to micrograms
We know that 1 milligram (mg) is equal to 1000 micrograms (mcg). Therefore, to convert the desired dose from mg to mcg, we multiply by 1000:
Desired dose (mcg) = Desired dose (mg)x 1000
Desired dose (mcg) = 0.25 mg x 1000 = 250 mcg
Step 2: Set up the proportion
We can use the following proportion to solve the problem:
(Desired dose) / (Available concentration) = Volume to administer
Step 3: Substitute the values
Plugging in the given values, we get:
(250 mcg) / (500 mcg/10 mL) = Volume to administer
Step 4: Simplify
To simplify, we can invert the denominator and multiply:
(250 mcg) x (10 mL / 500 mcg) = Volume to administer
The "mcg" units cancel out, leaving us with:
(250 x 10 mL) / 500 = Volume to administer
Step 5: Calculate
Performing the multiplication and division, we get:
2500/ 500 = Volume to administer
5 mL = Volume to administer

Correct Answer is B
Explanation
A) "There are specific pain management options that you need to use":
It’s important to respect the client's autonomy and work collaboratively to explore pain management options that align with their cultural values and medical safety. A more open, client-centered approach would be more beneficial.
B) "We will work with you to incorporate the practices that are safe for you and your fetus.":
This statement acknowledges the client's cultural preferences while ensuring that safety is the priority. The nurse is offering to collaborate with the client to explore pain management options that align with their values, within the scope of what is medically safe for both the mother and the fetus. It promotes a partnership approach, which is critical in maternity care.
C) "You will need to discuss this with the provider.":
While the provider may ultimately be involved in deciding specific pain management options, this statement dismisses the nurse's role in supporting the client’s cultural preferences. Nurses can play an active role in initiating and facilitating these conversations with clients and helping them express their preferences to the provider. It is not solely the provider's responsibility.
D) "It is better to use pain management options that have been researched.":
While evidence-based practices are important, this statement could be seen as dismissive of the client's cultural preferences. It fails to address the importance of individualized care and overlooks the possibility of integrating safe, culturally relevant pain management practices alongside researched methods. A balanced approach that respects both cultural values and medical safety is crucial.
Correct Answer is ["A","B","D"]
Explanation
A) Change client position every 30 minutes:
Changing positions regularly during the second stage of labor can help facilitate fetal descent and improve the effectiveness of contractions. This strategy also helps relieve pressure on certain areas of the body, such as the perineum and lower back, promoting more effective pushing and reducing the need for assisted delivery. Frequent position changes can help the mother progress in labor without the need for tools or interventions.
B) Upright positions:
Upright positions, such as standing, squatting, or kneeling, can be beneficial in the second stage of labor. These positions allow gravity to assist in the descent of the baby, which can help avoid the need for forceps or vacuum extraction. Upright positions also tend to open up the pelvis and can result in more effective pushing, reducing the likelihood of an assisted vaginal delivery.
C) Supine positions:
Supine positions (lying on the back) are not recommended for avoiding an assisted vaginal birth. Lying on the back can hinder fetal descent and may also lead to increased pressure on the inferior vena cava, which can decrease blood flow and oxygen to the uterus. This position tends to slow down labor and may increase the need for interventions like forceps or vacuum extraction, making it less favorable for a spontaneous vaginal delivery.
D) Lateral positions:
Lateral positions (lying on one side) can also help in the second stage of labor. This position can improve uterine blood flow, relieve pressure on the perineum, and provide more room for the baby to descend. It is a good alternative to supine positions and can aid in achieving a vaginal birth without assistance.
E) Delayed pushing:
Delayed pushing can be helpful for some clients, especially if they are not fully dilated or if they need time to rest. However, delayed pushing is not directly related to preventing an assisted vaginal birth. In fact, if the mother waits too long to push or doesn't push effectively, it could potentially lead to more complications or require assisted interventions. The key is ensuring that pushing is done effectively and at the right time in the second stage, rather than delaying it unnecessarily.
