A nurse is preparing to administer labetalol 40 mg IV to a client. Available is labetalol 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["8"]
Calculation:
Desired dose = 40 mg.
Available concentration = 5 mg/mL.
- Calculate the volume to administer.
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 40 mg / 5 mg/mL
= 8 mL.

Correct Answer is C
Explanation
Rationale:
A. "Maintain the client in a supine position for 24 hours following surgery.": Prolonged supine positioning increases the risk of pulmonary complications such as atelectasis. Early mobilization and elevating the head of the bed help promote lung expansion and reduce postoperative risks.
B. "Expect the client to have a palpable distended bladder following surgery.": A distended bladder is not expected and may indicate urinary retention, a common complication after anesthesia. The nurse should assess and address it promptly, rather than consider it normal.
C. "Report bleeding that saturates the client's dressing.": Active bleeding that saturates a postoperative dressing may indicate hemorrhage and requires immediate intervention. Reporting this finding is critical to prevent further complications like hypovolemia or shock.
D. "Ensure the client's urinary output is no less than 20 mL per hour.": Urine output should be at least 30 mL per hour in adults. A rate below this may indicate hypoperfusion or renal impairment and should prompt further assessment and intervention.
Correct Answer is ["A","B","E"]
Explanation
Rationale:
A. Administer Ibuprofen 200 mg PO: The child reports a pain score of 5/10 and is requesting pain medication. The provider has prescribed ibuprofen PRN for this level of pain. Prompt administration supports comfort and reduces inflammation associated with fracture and swelling.
B. Elevate the affected forearm with pillows: Elevation helps reduce edema by promoting venous return and lymphatic drainage. Given the child's worsening edema in the forearm and fingers, this is a priority to minimize complications like compartment syndrome.
C. Place a nonadherent dressing on the right knee abrasion: Although dressing the abrasion is a reasonable intervention, it is not a priority at this stage. The abrasion is not actively bleeding or infected, so attention should remain on managing neurovascular risk and pain.
D. Review cast care instructions with the child's parents: This is an important educational step, but it is not a current priority since the cast has not yet been applied. Priority actions should focus on pain, swelling, and circulation while awaiting casting.
E. Apply ice packs to the fingers and along the right forearm: Ice helps manage pain and inflammation by vasoconstriction, limiting fluid accumulation in tissues. Applying it early post-injury is crucial to controlling swelling in a fractured limb.
F. Explain the cast application procedure to the child: Preparing the child for a future procedure is helpful but not immediately necessary. At this point, pain control and reduction of swelling take precedence to prevent complications and stabilize the injury.
