A nurse is caring for a client ordered ceftazidime 1g IM every 6 hours. The drug comes in a vial with a powder which is reconstituted with 3mL of sterile water for a final concentration of 280 mg/mL. How many mi. will be drawn into the syringe for the dose ordered? Do not use leading zero (Round to the tenth)
The Correct Answer is ["3.6"]
Given:
Desired dose: Ceftazidime 1 g IM every 6 hours
Available concentration: Ceftazidime 280 mg/mL
To find:
Volume to administer (in mL)
Step 1: Convert desired dose to milligrams
1 gram (g) is equal to 1000 milligrams (mg).
Multiply by 1000:
Desired dose (mg) = Desired dose (g) x 1000
Desired dose (mg) = 1 g x 1000 = 1000 mg
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:
(1000 mg) / (280 mg/mL) = Volume to administer
Step 4: Simplify
To simplify, we can invert the denominator and multiply:
(1000 mg) x (1 mL / 280 mg) = Volume to administer
The "mg" units cancel out, leaving us with:
(1000 x 1 mL) / 280 = Volume to administer
Step 5: Calculate
Performing the multiplication and division, we get:
1000 mL / 280 = Volume to administer
3.57 mL ≈ Volume to administer
Step 6: Round to the nearest tenth
3.6mL

Correct Answer is B
Explanation
A) Milia:
Milia are tiny white or yellowish cysts that appear on a newborn's face, particularly on the nose, chin, or forehead. They are caused by the accumulation of keratin under the skin. Milia usually disappear within a few weeks of life and are not related to the pinkish marks described in the question.
B) Telangiectatic nevi (stork bites):
This finding is consistent with telangiectatic nevi, also known as stork bites. These are flat, irregular, pinkish-red marks often found on the forehead, eyelids, and nape of the neck. They are caused by dilated capillaries in the skin and are common in newborns. The marks blanch when pressed and are usually harmless, disappearing within the first 1-2 years of life. This is the correct answer based on the description provided in the question.
C) Nevus flammeus (port wine stain):
A port wine stain is a dark red to purple, flat birthmark caused by capillary malformations. Unlike stork bites, a port wine stain does not blanch when pressed and is typically present for life. It usually appears on the face, neck, or arms, and the coloration remains the same over time.
D) Nevus vasculosus (strawberry mark):
A strawberry mark is a raised, red, and bumpy birthmark that results from proliferation of capillaries. These marks typically appear in the first few weeks of life and grow in size before eventually shrinking and disappearing by the age of 5-10 years. Strawberry marks are not flat, pinkish, or blanchable, making this option unlikely in the scenario described.
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.
