A nurse is caring for an adolescent client who has pneumonia and a prescription for cefpodoxime 5 mg/kg PO for 5 days. The client weighs 88 lb. How many mg should the nurse administer? (Round the answer to the nearest whole number)
The Correct Answer is ["200"]
Weight in kg=Weight in lb÷2.2
Weight in kg=88÷2.2≈40
Calculate the dose of cefpodoxime:
The prescribed dose is 5 mg/kg.
Dose in mg=Weight in kg×Dose per kg
Dose in mg=40×5=200
The nurse should administer 200 mg of cefpodoxime.

Correct Answer is B
Explanation
A. There is no need for the client to lie flat for an extended period after a DEXA scan. The procedure is non-invasive and does not require immobilization.
B. Emptying the bladder before the test is essential to ensure a clear and accurate scan of the pelvis and lower spine. A full bladder might obstruct the view and affect the accuracy of the results.
C. DEXA scans do not typically require the use of IV dye. It is a simple X-ray procedure that measures bone density, and no contrast material is usually needed.
D. Fasting is not necessary for a DEXA scan. The procedure does not involve ingesting or injecting any substances that require fasting.
Correct Answer is A
Explanation
Explanation:
A. Promptly inform the primary provider:
Explanation: Compartment syndrome is a medical emergency that requires immediate intervention. If a nurse suspects compartment syndrome due to symptoms like severe unrelieved pain, absent pulses, and pale extremities, the most appropriate action is to promptly inform the primary healthcare provider. The provider can assess the situation, order necessary diagnostic tests, and potentially arrange for emergent interventions like fasciotomy to relieve compartment pressure.
B. Reassess the client's neurovascular status in 15 minutes:
Explanation: Waiting for 15 minutes to reassess the client's neurovascular status is not appropriate in this situation. Compartment syndrome can progress rapidly, leading to irreversible tissue damage within a short time frame. Delaying assessment and intervention can result in significant complications.
C. Warm the client's foot and determine whether circulation improves:
Explanation: Warming the foot is not appropriate in this context. Compartment syndrome is caused by increased pressure within the muscle compartment, leading to compromised circulation. Warming the foot will not address the underlying issue of elevated compartment pressure and can potentially worsen the condition by dilating blood vessels and increasing pressure further.
D. Reposition the client with the affected foot dependent:
Explanation: Repositioning the client with the affected foot dependent is contraindicated in compartment syndrome. Elevating the limb can worsen the condition by further restricting blood flow. The limb should be kept at or slightly below the level of the heart to maintain adequate perfusion until medical intervention can be initiated.
