Foundations and Adult Health Nursing Study Guide Answers Questions
Question 1 of 5
A patient presents with bone pain, fatigue, and frequent infections. Laboratory tests reveal pancytopenia, hypocellular bone marrow, and absence of reticulocytes. Which of the following conditions is most likely to cause these findings?
Correct Answer: A
Rationale: Aplastic anemia is a condition characterized by a reduction in the number of all three blood cell types: red blood cells, white blood cells, and platelets. The patient's presentation of bone pain, fatigue, frequent infections, pancytopenia (decreased counts of all blood cell types), hypocellular bone marrow (reduced cellularity in the bone marrow), and absence of reticulocytes is indicative of aplastic anemia.
Question 2 of 5
A patient presents with fatigue, pallor, and exertional dyspnea. Laboratory tests reveal severe anemia, low serum iron, low transferrin saturation, and elevated total iron-binding capacity (TIBC). Which of the following conditions is most likely to cause these findings?
Correct Answer: A
Rationale: The clinical presentation of fatigue, pallor, exertional dyspnea along with the laboratory findings of severe anemia, low serum iron, low transferrin saturation, and elevated TIBC are consistent with iron deficiency anemia. In iron deficiency anemia, there is inadequate iron available for erythropoiesis leading to microcytic hypochromic anemia. The low serum iron and transferrin saturation, along with the elevated TIBC, indicate decreased iron stores and increased iron-binding capacity as the body tries to compensate for the deficiency by increasing absorption and recycling of iron. Anemia of chronic disease typically presents with mild to moderate anemia, normal to low TIBC, and low transferrin saturation due to iron sequestration in macrophages. Sideroblastic anemia usually has elevated serum iron, high saturation, and normal to low TIBC. Thalassemia presents with microcytic hyp
Question 3 of 5
A patient presents with sudden-onset severe headache, altered mental status, and focal neurological deficits. Imaging reveals a hemorrhagic lesion within the right basal ganglia. Which of the following neurological conditions is most likely responsible for these symptoms?
Correct Answer: C
Rationale: Intracerebral hemorrhage occurs when there is bleeding directly into the brain tissue, often due to conditions such as hypertension or vascular malformations. The sudden-onset severe headache, altered mental status, and focal neurological deficits described in the patient are typical symptoms of an intracerebral hemorrhage. The location of the hemorrhagic lesion within the right basal ganglia corresponds to the clinical presentation. Ischemic stroke, subarachnoid hemorrhage, and transient ischemic attack (TIA) typically have different presentations and imaging findings compared to an intracerebral hemorrhage. Therefore, in this scenario, intracerebral hemorrhage is the most likely cause of the patient's symptoms.
Question 4 of 5
A patient presents with sudden-onset weakness and sensory loss on one side of the body, along with difficulty speaking and understanding speech. Symptoms began approximately 1 hour ago and have partially resolved since then. Which of the following neurological conditions is most likely responsible for these symptoms?
Correct Answer: B
Rationale: The patient's presentation of sudden-onset weakness and sensory loss on one side of the body, along with difficulty speaking and understanding speech that partially resolved within one hour, is consistent with a transient ischemic attack (TIA). TIAs are caused by temporary disruption of blood flow to a part of the brain, leading to transient neurological symptoms. Unlike an ischemic stroke, which results in permanent damage to brain tissue due to prolonged interruption of blood flow, TIAs are transient and resolve within 24 hours. Hemorrhagic strokes and subarachnoid hemorrhages typically present with sudden, severe headaches, and may not improve or resolve quickly as seen in this case.
Question 5 of 5
When communicating with a patient from a different cultural background, what should the nurse prioritize?
Correct Answer: C
Rationale: When communicating with a patient from a different cultural background, the nurse should prioritize recognizing and respecting the patient's cultural beliefs and practices. This is essential in providing culturally competent care, fostering trust and rapport with the patient, and ultimately improving health outcomes. By acknowledging and understanding the cultural context of the patient, the nurse can adapt communication strategies, address the patient's needs effectively, and avoid misunderstandings or misinterpretations. Building a culturally sensitive approach can enhance the quality of care and strengthen the therapeutic relationship between the nurse and patient.
