Question 1 of 5
Which of the following is NOT a clinical sign of Hemolytic anemia:
Correct Answer: A
Rationale: Cyanosis is the bluish discoloration of the skin or mucous membranes due to insufficient oxygen in the blood. It is not a typical clinical sign of hemolytic anemia. Hemolytic anemia is characterized by the premature destruction of red blood cells, leading to symptoms such as abdominal pain, hemoglobinuria (presence of hemoglobin in the urine), jaundice (yellowing of the skin and eyes), and sometimes lower back pain due to kidney involvement. Cyanosis is more commonly associated with respiratory or cardiovascular conditions where oxygen levels are affected.
Question 2 of 5
What is the primary action of interferon alfa?
Correct Answer: C
Rationale: Interferon alfa is an immunomodulatory agent that works by enhancing the immune system's ability to fight cancer. It has cytotoxic and cytostatic effects, meaning it can kill cancer cells or inhibit their growth. Additionally, it promotes the differentiation of stem cells, which can help restore normal cell function. While interferon alfa does produce cytokines and interleukins, its primary action is immunomodulation and direct effects on cancer cells. It does not primarily cause allergic reactions or produce red blood cells.
Question 3 of 5
A 55-year-old man is concerned about hair loss. The nurse expects that the patient’s baldness may be treated with which drug?
Correct Answer: D
Rationale: Finasteride is an FDA-approved medication for male pattern baldness (androgenetic alopecia). It works by inhibiting the conversion of testosterone to dihydrotestosterone, which is responsible for hair follicle miniaturization. Dexamethasone (A), para-aminobenzoic acid (B), and mupirocin (C) are not used to treat hair loss.
Question 4 of 5
A patient who has advanced cancer is receiving opioid medications around the clock to 'keep him comfortable' as he nears the end of his life. Which term best describes this type of therapy?
Correct Answer: A
Rationale: Palliative therapy focuses on relieving symptoms and improving quality of life for patients with serious or life-limiting illnesses, such as advanced cancer. The goal is not to cure the disease but to provide comfort and alleviate suffering. In this case, the patient is receiving opioids around the clock to manage pain and ensure comfort, which is a hallmark of palliative care. Maintenance therapy is used to sustain a patient's condition, supportive therapy addresses specific symptoms, and supplemental therapy provides additional treatment. Therefore, palliative therapy is the most appropriate term for this scenario.
Question 5 of 5
Nurse Bryan knows that the age group that uses the most units of blood and blood products is:
Correct Answer: D
Rationale: The elderly above age 65 years are the largest consumers of blood and blood products due to the higher prevalence of chronic diseases, surgeries, and medical conditions that require transfusions, such as anemia, cancer, and cardiovascular diseases. While premature infants and children may require blood products, their overall usage is lower compared to the elderly population. Adults aged 21-64 also use blood products, but the demand is highest among the elderly due to their increased healthcare needs.
