Question 1 of 5
The primary underlying disorder of pulmonary edema is:
Correct Answer: A
Rationale: Pulmonary edema is a condition where fluid accumulates in the air sacs of the lungs, leading to difficulty breathing. The primary underlying disorder of pulmonary edema is often decreased left ventricular pumping. When the left ventricle of the heart fails to effectively pump blood to the rest of the body, it can lead to a backlog of blood in the pulmonary circulation. This increase in pressure in the pulmonary circulation can cause fluid to leak out of the capillaries and into the alveoli of the lungs, resulting in pulmonary edema. Therefore, decreased left ventricular pumping is a key factor in the development of pulmonary edema.
Question 2 of 5
Once admitted to hospital the physician indicates that Mr. Gubatan is a paraplegic. The family asks the nurse what that means. The nurse explains that:
Correct Answer: C
Rationale: Paraplegia is a condition characterized by the paralysis of both lower extremities. It does not affect the upper extremities or one side of the body specifically. When someone is described as a paraplegic, it means they have lost function and sensation in their lower limbs, usually due to a spinal cord injury or disease affecting the lower part of the spinal cord. This term helps provide a specific understanding of the type and location of the paralysis in the body.
Question 3 of 5
A client with acquired immunodeficiency syndrome (AIDS) is receiving zidovudine (azidothymidine, AZT [Retrovir]). To check for adverse drug effects, the nurse should monitor the results of laboratory test?
Correct Answer: D
Rationale: Zidovudine (azidothymidine, AZT [Retrovir]) is an antiretroviral medication used to treat human immunodeficiency virus (HIV) infection. One of the potential adverse effects of zidovudine is bone marrow suppression, which can lead to decreased production of blood cells including platelets. Monitoring the platelet count is essential because a low platelet count (thrombocytopenia) can result in an increased risk of bleeding and bruising. Therefore, regular monitoring of platelet count is crucial to detect and manage this potential adverse effect promptly in patients receiving zidovudine therapy. Monitoring other laboratory tests such as RBC count, serum calcium, and fasting blood glucose may also be important for assessing overall health status, but platelet count monitoring takes priority due to the risk of thrombocytopenia associated with zidovudine therapy.
Question 4 of 5
You have the results of PCR tests for Mycoplasma pneumoniae; the number of positive tests is 83 collected from a 100 truly-infected persons. The sensitivity of this test is
Correct Answer: D
Rationale: Sensitivity = (True positives / Truly infected) * 100 = (83 / 100) * 100 = 83%.
Question 5 of 5
Osteosarcoma is the most common primary malignant bone tumor in children and adolescents; it has multiple subtypes and requires different modalities of treatment including surgery and chemotherapy. Of the following, the subtype of osteosarcoma which is treated by surgery alone is
Correct Answer: D
Rationale: Periosteal osteosarcoma is often treated with surgery alone if margins are clear.
