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 C
Explanation
A) Fetal heart monitoring:
Nurses are trained to monitor fetal heart rates, interpret patterns, and identify signs of distress, but this task is typically within the scope of a registered nurse's (RN) practice. It may not involve the critical decision-making or advanced skills associated with the highest level of licensure.
B) Taking specimens to the lab:
Taking specimens to the laboratory is a necessary but routine part of care. While it is important for ensuring proper diagnostic testing, it is a lower-level task and does not demonstrate the highest level of nursing practice. This task is often delegated or performed as part of standard nursing duties.
C) Performing vaginal delivery:
Performing a vaginal delivery is a high-level skill that typically requires advanced education, certification, and licensure beyond that of a registered nurse. This is usually performed by a midwife, obstetrician, or other healthcare providers with advanced training and certification. In many settings, a registered nurse may assist with vaginal deliveries but cannot independently perform them unless they have additional certifications (such as Certified Nurse Midwife).
D) Giving a client a bed bath:
While important for patient care and comfort, giving a client a bed bath is a basic nursing task that does not demonstrate working at the highest level of licensure. It is a fundamental nursing activity often carried out by nurses, nursing assistants, or other support staff. The act of providing a bed bath is part of the foundational skill set and does not require advanced knowledge or decision-making that would demonstrate the highest level of practice.
Correct Answer is C
Explanation
A) Decrease the heart rate of the fetus:
Lying on the left side can sometimes help improve fetal oxygenation, especially if there is a concern about reduced blood flow from compression of the inferior vena cava, which can occur when the mother lies on her back. However, the primary rationale for this position is to prevent supine hypotension, not specifically to decrease fetal heart rate. In fact, side-lying can promote better oxygen exchange, which can indirectly benefit the fetal heart rate.
B) Aid the women while she pushes:
While a left-side lying position may offer comfort during labor and can help with uterine positioning, it is not specifically intended to aid in the pushing phase. Positions such as squatting or hands-and-knees are generally more helpful during the pushing phase because they can facilitate effective pushing and help the baby descend into the birth canal. The left-side position is more about circulation and preventing hypotension.
C) Prevent supine hypertension:
Supine hypotension occurs when the pregnant woman lies flat on her back, which can compress the inferior vena cava and reduce blood return to the heart. This leads to a drop in blood pressure and can compromise both maternal and fetal circulation. The left-side position is recommended because it helps to prevent this compression and allows optimal blood flow to both the mother and fetus, improving oxygenation and circulation.
D) Prevent the client from falling out of bed:
While lying on the left side may make the woman feel more stable, the primary reason for this position is to prevent supine hypotension, not to prevent her from falling out of bed. The nurse would ensure safety by using appropriate bed rails and monitoring, but the primary concern is supporting optimal circulation, not preventing falls.
