A client is ordered ampicillin 0.5 g po every 6 hours. On hand are ampicillin capsules labeled 250mg. How many capsules will the nurse administer for single dose?
The Correct Answer is ["2"]
Given:
Desired dose: Ampicillin 0.5 g PO
Available concentration: Ampicillin capsules 250 mg each
To find:
Number of capsules to administer for a single dose
Step 1: Convert desired dose to milligrams
We know that 1 gram (g) is equal to 1000 milligrams (mg). Therefore, to convert the desired dose from grams to milligrams, we multiply by 1000:
Desired dose (mg) = Desired dose (g) x 1000
Desired dose (mg) = 0.5 g x 1000 = 500 mg
Step 2: Calculate the number of capsules
To find the number of capsules, we divide the desired dose by the strength of each capsule:
Number of capsules = Desired dose / Capsule strength
Number of capsules = 500 mg / 250 mg/capsule = 2 capsules

Correct Answer is A
Explanation
A) A stool softener as needed:
Fibrinogen levels are elevated during pregnancy as part of the body's natural response to the increased risk of bleeding at birth. While this helps to prevent hemorrhage, it also increases the risk of clot formation, which can lead to postpartum complications such as deep vein thrombosis (DVT) or pulmonary embolism (PE). To prevent these complications, one recommended strategy is to use a stool softener. This helps prevent constipation, which can strain the body and increase the risk of developing blood clots due to the Valsalva maneuver during straining. Stool softeners reduce the likelihood of this strain, supporting overall circulation and reducing the risk of clotting.
B) Urinate every two to three hours:
While frequent urination is important for general bladder health, particularly in the immediate postpartum period to avoid urinary retention, it is not directly related to preventing complications associated with elevated fibrinogen levels. Fibrinogen's main risk is related to clotting, and frequent urination does not affect this process.
C) Eat a diet high in protein:
While eating a balanced diet with adequate protein is essential for postpartum recovery and tissue healing, it does not directly address the increased fibrinogen levels or the potential for clotting. A high-protein diet does not significantly reduce the risks related to hypercoagulability during the postpartum period, which is primarily managed through careful monitoring and preventive measures such as using stool softeners or encouraging movement.
D) Walk:
While walking is beneficial for overall health and can help improve circulation, reducing the risk of DVT and promoting postpartum recovery, walking alone may not be sufficient to counteract the increased clotting risk from elevated fibrinogen levels. While movement is important to prevent clots, the use of stool softeners to prevent constipation is a more direct and targeted intervention for preventing strain, which could trigger clot formation. Therefore, walking, while helpful, is not the most specific measure to prevent complications related to increased fibrinogen.
Correct Answer is {"dropdown-group-1":"C","dropdown-group-2":"D"}
Explanation
Uterine rupture: A client in active labor with a history of prior vaginal birth is at risk for uterine rupture, particularly when experiencing intense contractions and increasing pelvic pressure. While previous vaginal delivery lowers the risk compared to a history of cesarean section, prolonged or strong contractions can still contribute to uterine rupture, especially if there is an undiagnosed uterine scar or excessive uterine stress.
Increasing pelvic pressure: The client reports increasing pelvic pressure despite receiving an epidural, which can be a sign of impending uterine rupture. While pelvic pressure is expected during labor, a sudden or intense sensation, particularly in the setting of strong contractions and rapid cervical dilation, warrants close monitoring.
