Two days after surgical fixation of a fractured femur, a client suddenly reports chest pain and difficulty in breathing. The nurse suspects the client had a pulmonary embolus. Which action should the nurse take first?

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.

The correct answer is A, B, C, and D.

Choice A reason: Flushing the gastrostomy tube with water is essential to maintain tube patency and prevent medication interactions. It should be done before and after medication administration. The typical amount of water used for flushing can range from 15 to 30 mL.

Choice B reason: Administering each medication separately is a critical practice to prevent drug interactions and ensure that the full dose of each medication is delivered. It also helps in preventing the clogging of the tube.

Choice C reason: Documenting all liquid volumes, including medications and water used for flushing, is important for accurate fluid intake records. This helps in maintaining fluid balance and monitoring the patient’s hydration status.

Choice D reason: Checking gastric residual volume is important to assess the patient’s tolerance to enteral feeding and to prevent complications such as aspiration. Normal gastric residual volumes are generally considered to be less than 250 mL.

Choice E reason: Using a plunger to administer medications through a gastrostomy tube is not always recommended. Medications should be administered slowly to prevent discomfort or harm, and the use of a plunger is not a standard practice across all healthcare settings.
