An older client who is agitated, dyspneic, orthopneic, and using accessory muscles to breathe is admitted for further treatment. Initial assessment includes a heart rate of 128 beats/minute and irregular, respirations of 38 breaths/minute, blood pressure of 168/100 mm Hg, and oxygen saturation of 90% on room air. Wheezes and crackles are noted throughout bilateral lung fields. An hour after the administration of furosemide 60 mg IV push (IVP), which assessments should the nurse obtain to determine the client's response to treatment? Select all that apply.

Choice A reason: Pain in the lower legs when walking, also known as intermittent claudication, is a common symptom of PAD but does not indicate an immediate threat to limb viability.

Choice B reason: Black eschar over the ankle ulcer indicates necrotic tissue, which is concerning but not as immediately critical as absent pulses. It does need to be monitored and treated to prevent infection and further complications.

Choice C reason: Absent pedal pulses by Doppler indicate a significant reduction in blood flow to the lower extremities, which can lead to critical limb ischemia and requires immediate intervention to restore perfusion and prevent tissue loss.

Choice D reason: Dependent rubor (redness when the leg is in a dependent position) is a sign of poor arterial circulation but does not require as urgent intervention as absent pedal pulses.

Choice A reason: Lethargy and lack of appetite are symptoms that might indicate hypothyroidism or an insufficient dosage of levothyroxine. These symptoms are not typically associated with a dosage that is too high.

Choice B reason: Bradycardia and constipation are also indicative of hypothyroidism or an inadequate dosage of levothyroxine. These symptoms suggest a need for a higher dosage rather than indicating that the current dosage is too high.

Choice C reason: Muscle cramping and dry, flushed skin can be associated with electrolyte imbalances or dehydration, but they are not specific symptoms of an excessive dosage of levothyroxine.

Choice D reason: Palpitations and shortness of breath are signs of hyperthyroidism, which can occur if the dosage of levothyroxine is too high. These symptoms indicate that the client's metabolism is excessively stimulated, leading to cardiovascular strain and respiratory distress. It is crucial for the nurse to monitor these symptoms and adjust the medication dosage accordingly.
