The Correct Answer is ["A","B","C","D","G"]
Rationale for correct findings:
• Hemoglobin 12 g/Dl: The client’s hemoglobin increased from 9.1 g/dL to 12 g/dL following the transfusion of 2 units of packed RBCs. This demonstrates improved oxygen-carrying capacity and correction of anemia, reflecting a positive response to the intervention.
• Hematocrit 36%: The rise in hematocrit from 27% to 36% indicates improved red blood cell volume and overall blood oxygenation. This laboratory improvement confirms that the transfusion effectively restored circulating red blood cells and addressed the client’s prior anemia.
• Blood pressure 112/74 mm Hg: The client’s blood pressure increased from 90/50 mm Hg to 112/74 mm Hg, suggesting improved hemodynamic stability. This indicates better perfusion and a positive response to both transfusion and supportive care.
• Heart rate 95/min: The decrease in heart rate from 118/min to 95/min reflects reduced compensatory tachycardia associated with anemia and hypovolemia. This demonstrates improved cardiovascular status following transfusion.
• Oxygen saturation 100% via 2 L/min nasal cannula: Oxygen saturation improved from 98% on room air to 100% on supplemental oxygen, indicating enhanced oxygen delivery and tissue perfusion. This is an objective sign of recovery from anemia and improved respiratory efficiency.
Rationale for incorrect findings
• Temperature 37.5°C (95°F): The temperature remained essentially unchanged and within normal limits. While important to monitor for infection or transfusion reactions, this finding does not reflect improvement in oxygen-carrying capacity or hemodynamic status.
• Respiratory rate 18/min: The respiratory rate remained stable and within normal limits. Although stability is positive, it does not directly reflect the improvements in hemoglobin, hematocrit, blood pressure, or oxygen saturation resulting from the transfusion.

Correct Answer is D
Explanation
Rationale:
A. Administer a continuous infusion of calcium gluconate: Calcium gluconate is not used for the management of preeclampsia or seizure prophylaxis. Magnesium sulfate is the medication of choice to prevent eclamptic seizures in clients with severe preeclampsia.
B. Place the client in the semi-Fowler's position: Semi-Fowler’s position does not optimize uteroplacental perfusion. Left lateral positioning is preferred to enhance blood flow to the uterus and improve maternal and fetal oxygenation.
C. Ensure bright lighting in the room: Bright lighting can increase stimulation and anxiety, which is not beneficial for a client at risk for seizures. A calm, low-stimulation environment is preferable to minimize seizure triggers.
D. Initiate seizure precautions: Clients with preeclampsia with severe features are at high risk for eclampsia, making seizure precautions essential. These include placing the bed in a low position, padding side rails, having oxygen and suction available, and monitoring closely for neurologic changes.
Correct Answer is A
Explanation
Rationale:
A. Stair carpeting is attached with carpet tacks: Loose or improperly secured carpeting on stairs creates a significant tripping hazard, especially for clients with mobility limitations such as a hip fracture. Carpet tacks can cause the edges of the carpet to lift, increasing the risk of falls and further injury.
B. Nonessential items are stored in drawers: Storing nonessential items in drawers does not create an immediate fall risk or safety hazard. Keeping items organized in drawers can actually reduce clutter in walking areas, making the environment safer.
C. Magazines are stacked neatly on the stairs: Even neatly stacked magazines on stairs are a potential tripping hazard. However, the option specifies “neatly stacked,” which implies some order, though ideally items should not be on stairs at all. Carpet tacks pose a more immediate and hidden danger than visible items.
D. End tables are secured to the wall: Securing furniture prevents tipping and provides stability, which enhances safety for clients with mobility limitations. This measure decreases the risk of falls and does not pose a hazard.
