The nurse identifies which patient condition may be treated with a tissue plasminogen activator?

Idiopathic pulmonary fibrosis

Sarcoidosis

Atelectasis

Pulmonary embolus (PE)

Answer and Explanation

The Correct Answer is D

Choice A reason: Idiopathic pulmonary fibrosis is a chronic, progressive lung disease characterized by scarring of the lung tissue. Tissue plasminogen activators (tPAs) are not used for this condition, as they are primarily designed to dissolve blood clots, not to address fibrotic changes in the lungs.

Choice B reason: Sarcoidosis is an inflammatory disease that affects multiple organs, particularly the lungs and lymph glands. It involves the growth of tiny collections of inflammatory cells called granulomas. Tissue plasminogen activators are not used in the treatment of sarcoidosis since the condition is not related to blood clots but rather to immune system dysregulation.

Choice C reason: Atelectasis is the complete or partial collapse of a lung or lobe of a lung due to alveoli deflation. The treatment typically focuses on re-expanding the lung tissue through techniques such as deep breathing exercises, bronchoscopy, or mechanical ventilation. Tissue plasminogen activators are not relevant for this condition, as they are used to dissolve blood clots, not to treat lung collapse.

Choice D reason: Pulmonary embolus (PE) is a blockage in one of the pulmonary arteries in the lungs, usually caused by blood clots that travel to the lungs from the legs or other parts of the body (deep vein thrombosis). Tissue plasminogen activators are used to treat PE because they can effectively dissolve the blood clots obstructing the pulmonary arteries, thereby restoring normal blood flow and preventing further complications.

Correct Answer is ["B","C","D"]

Explanation

Choice A reason: Fluid restrictions are not appropriate for stabilizing a patient with acute anemia. In fact, patients with anemia might require fluid resuscitation to maintain adequate blood volume and pressure. Restricting fluids could potentially worsen the patient's condition.

Choice B reason: Iron supplements are necessary for patients with acute anemia, especially if the anemia is due to iron deficiency. Supplementation helps replenish iron stores in the body, aiding in the production of hemoglobin and red blood cells which are critical for carrying oxygen to tissues.

Choice C reason: PRBC (Packed Red Blood Cells) transfusion is a common and effective intervention for acute anemia. It quickly increases the number of red blood cells in the patient's circulation, thereby improving oxygen delivery to tissues and alleviating symptoms of anemia such as fatigue and weakness.

Choice D reason: O2 therapy, or oxygen therapy, is crucial for stabilizing patients with acute anemia. Anemia results in reduced oxygen-carrying capacity of the blood, and supplemental oxygen helps ensure that tissues receive sufficient oxygen. This intervention can be lifesaving in severe cases of anemia.

A. Metabolic acidosis B. Metabolic alkalosis C. Respiratory acidosis D. Respiratory alkalosis

Correct Answer is D

Explanation

Choice A reason: Metabolic acidosis is characterized by a decrease in blood pH (less than 7.35) due to a primary decrease in bicarbonate (HCO₃). The arterial blood gas results in this scenario do not indicate metabolic acidosis, as the pH is elevated and HCO₃ is within the normal range.

Choice B reason: Metabolic alkalosis is characterized by an increase in blood pH (greater than 7.45) due to a primary increase in bicarbonate (HCO₃). In this case, the pH is indeed elevated, but the bicarbonate level is normal, making this condition unlikely.

Choice C reason: Respiratory acidosis is characterized by a decrease in blood pH (less than 7.35) due to a primary increase in PaCO₂. The arterial blood gas results show an elevated pH and a decreased PaCO₂, which are not consistent with respiratory acidosis.

Choice D reason: Respiratory alkalosis is characterized by an increase in blood pH (greater than 7.45) due to a primary decrease in PaCO₂. In this scenario, the pH is elevated at 7.48, and the PaCO₂ is decreased at 32 mm Hg, indicating respiratory alkalosis. The bicarbonate level is within the normal range, further supporting this interpretation.
