Extract:
Question 1 of 5
The client is admitted with a diagnosis of preterm premature rupture of membranes (PPROM). The nurse should prepare to administer which medication?
Correct Answer: C
Rationale: Betamethasone is administered in PPROM (24-34 weeks) to enhance fetal lung maturity in anticipation of preterm delivery. Magnesium sulfate may be used for neuroprotection or preeclampsia and terbutaline is a tocolytic but betamethasone is the priority.
Question 2 of 5
The nurse is caring for a client following a cerebral vascular accident. Which portion of the brain is responsible for changes in the client's vision?
Correct Answer: C
Rationale: The occipital lobe processes visual information. A cerebral vascular accident affecting this area can cause visual deficits such as hemianopia or visual agnosia. The temporal lobe manages auditory and memory functions, the frontal lobe controls behavior and motor skills, and the parietal lobe handles sensory integration.
Question 3 of 5
When giving discharge instructions to a 24-year-old client who had a short-arm cast applied for a fractured right ulna, the nurse recognizes the importance of telling him that the drying time for a plaster of Paris cast is approximately:
Correct Answer: D
Rationale: Synthetic cast materials harden in 3-15 minutes. Weight bearing is permitted in 15-30 minutes. Drying time for plaster of Paris is about 24-72 hours. (B,
C) Plaster of Paris cast materials are heavier than synthetic materials and require a drying time of 24-72 hours. Synthetic materials dry within 30 minutes. Plaster of Paris cast materials are heavier than synthetic materials and require a longer period to set and dry. Even though setting time (hardening) is only 3-15 minutes, the drying time for plaster of Paris is 24-72 hours. This depends on the size and thickness of the cast, exposure to air, and humidity in the air.
Question 4 of 5
The nurse is caring for a client with a history of atrial fibrillation. Which medication is most likely to be prescribed to prevent thromboembolism?
Correct Answer: A
Rationale: Warfarin is commonly prescribed for atrial fibrillation to prevent thromboembolism by maintaining anticoagulation (target INR 2–3). Aspirin and clopidogrel are less effective, and heparin is used short-term.
Question 5 of 5
A client has been admitted to the labor and delivery unit in active labor. After assessing her, the RN notes that the client's fetus position is left occipital posterior. Which of the following statements best describes what this means to the labor process:
Correct Answer: B
Rationale: The left occipital posterior position presents a larger fetal head diameter, increasing pressure on sacral nerves and prolonging the first stage of labor due to slower fetal descent.
