Question 1 of 5
A nurse is assessing a dark-skinned client for pallor. What nursing assessment is best to assess for pallor in this client?
Correct Answer: A
Rationale: The correct answer is A: Assess the conjunctiva of the eye. Pallor is difficult to detect in dark-skinned individuals due to the lack of contrast. The conjunctiva of the eye provides a reliable area to assess for pallor as it is mucous membrane with blood vessels that can show changes in color. It is not accurate to assess for pallor by having the patient open the hand widely (B) as skin color on hands may vary. Looking at the roof of the mouth (C) may not accurately reflect pallor. Palpating for areas of mild swelling (D) does not assess for pallor, but rather for edema.
Question 2 of 5
A patient who is suspected of having acute viral hemorrhagic fever reveals history of tick bite. Which of the following is the most possible causative agent?
Correct Answer: C
Rationale: The correct answer is C: Crimean Congo virus. This is the most likely causative agent of acute viral hemorrhagic fever following a tick bite due to its association with tick transmission. Crimean Congo virus is a tick-borne virus that causes severe hemorrhagic fever in humans. The other options, Hantavirus, Rift Valley virus, and Marburg virus, are not typically transmitted by ticks. Hantavirus is spread through rodent feces, Rift Valley virus is transmitted by mosquitoes, and Marburg virus is transmitted through direct contact with infected animals or their bodily fluids. Therefore, based on the history of tick bite, Crimean Congo virus is the most probable causative agent.
Question 3 of 5
A patient is suffered from vitamin K deficiency. Which of the coagulation factors will not be affected?
Correct Answer: C
Rationale: The correct answer is C, Factor VIII. Vitamin K is crucial for the activation of Factors II, VII, IX, and X in the coagulation cascade. Factor VIII is not dependent on vitamin K for its synthesis or activation, so it will not be affected by vitamin K deficiency. Factors II, VII, and IX will be affected as they require vitamin K for their activation. Therefore, Factor VIII is the only factor that will not be impacted by vitamin K deficiency.
Question 4 of 5
Which of the following is not the criteria in the international prognostic index for non Hodgkin's lymphoma?
Correct Answer: C
Rationale: The correct answer is C: Lymphocyte count. The International Prognostic Index (IPI) for non-Hodgkin's lymphoma includes factors such as age, number of extranodal sites, LDH level, performance status, and stage. Lymphocyte count is not a specific criteria in the IPI. This index is used to predict the outcome of patients with aggressive lymphomas. A higher score indicates a worse prognosis. A low lymphocyte count is not a consistent prognostic factor for non-Hodgkin's lymphoma, unlike the other factors listed. Therefore, choice C is not a criteria in the IPI, making it the correct answer.
Question 5 of 5
A patient who is infected with hookworms produces signs and symptoms of anemia. Which of the following can be seen in the peripheral blood smear of the patient?
Correct Answer: B
Rationale: The correct answer is B: Basophilic stippling. Basophilic stippling is a common finding in the peripheral blood smear of patients infected with hookworms due to lead poisoning, which can occur as a result of hookworm infection. Basophilic stippling is seen as the presence of small, dark blue granules within red blood cells and is indicative of impaired heme synthesis. Howell-Jolly bodies (A) are remnants of nuclear material in red blood cells and are typically seen in patients with functional asplenia. Target cells (C) are seen in conditions such as liver disease and hemoglobinopathies. Spherocytes (D) are seen in conditions like hereditary spherocytosis or autoimmune hemolytic anemia, but not specifically in hookworm infection.
