The healthcare provider prescribes and IV solution of regular insulin (Humulin-R) 100 units in 250 ml of 0.45% saline to infuse at 12 units/hour. The nurse should program the infusion pump to deliver how many ml/hour?

Choice A reason: Keeping the bed in the lowest position and initiating seizure and fall precautions is not an immediate action for the nurse to take. Seizure and fall precautions are measures that prevent injury or harm to the client in case of a seizure or a fall. Seizure and fall precautions include lowering the bed, padding the side rails, removing any objects that may cause injury, and having suction and oxygen equipment ready. However, these precautions are not specific to the client's condition and do not address the underlying cause.

Choice B reason: Placing an indwelling urinary catheter and measuring strict intake and output is not an urgent action for the nurse to take. An indwelling urinary catheter is a tube that drains urine from the bladder into a collection bag. Measuring intake and output is a way of monitoring fluid balance and kidney function. However, these interventions are not essential for the client's condition and may increase the risk of infection or trauma.

Choice C reason: Maintaining elevated positioning of the dependent joints on affected side is not a relevant action for the nurse to take. Dependent joints are joints that are below the level of the heart, such as the ankles or wrists. Elevating dependent joints can help reduce swelling or pain by improving blood flow and drainage. However, this intervention is not related to the client's condition and does not improve neurological function.

Choice A: When the client has ankle edema is not the most important time for the nurse to assess DTRs, as this is a common finding in pregnancy and does not indicate a neurological or vascular problem. This is a distractor choice.

Choice B: Within the first trimester of pregnancy is not the most important time for the nurse to assess DTRs, as this is a routine assessment that can be done at any time during pregnancy and does not reflect any specific risk or complication. This is another distractor choice.

Choice C: If the client has an elevated blood pressure is the most important time for the nurse to assess DTRs, as this can indicate preeclampsia, a serious condition that can cause seizures, stroke, and organ damage. DTRs can help detect hyperreflexia, which is a sign of increased intracranial pressure and impending eclampsia. Therefore, this is the correct choice.

Choice D: During admission to labor and delivery is not the most important time for the nurse to assess DTRs, as this is a standard assessment that can be done at any stage of labor and does not signify any urgent or emergent situation. This is another distractor choice.
