The nurse is documenting findings after completing data collection with a patient. What term should the nurse use to document a large area of discoloration from hemorrhage under the skin?
- A. Pallor
- B. Rubor
- C. Petechiae
- D. Ecchymosis
Correct Answer: D
Rationale: The correct term for a large area of discoloration from hemorrhage under the skin is "Ecchymosis" (Choice D). Ecchymosis refers to the medical term for a bruise, which is characterized by a large area of skin discoloration caused by bleeding beneath the skin due to trauma or injury. Pallor (Choice A) refers to paleness of the skin due to decreased blood flow or anemia, not discoloration from hemorrhage. Rubor (Choice B) refers to redness of the skin due to increased blood flow, not discoloration from hemorrhage. Petechiae (Choice C) are tiny red or purple spots on the skin caused by broken capillaries, not a large area of discoloration from hemorrhage as described in the question.

Half life of plat. Is:
- A. 1-2days
- B. 3-4days
- C. 5-6days
- D. 7-8days
Correct Answer: B
Rationale: The correct answer is B: 3-4 days. The half-life of a substance is the time it takes for half of the original amount to decay. In this case, since the half-life of platinum is 3-4 days, it means that after 3-4 days, half of the initial amount of platinum will have decayed. This answer is correct because it accurately represents the time frame for platinum decay. The other choices are incorrect because they do not correspond to the known half-life of platinum. Choice A (1-2 days), C (5-6 days), and D (7-8 days) are outside the typical half-life range for platinum, making them incorrect options.
Artemisinin and its derivatives are used in the treatment of severe forms of chloroquine-resistant falciparum because they have:
- A. Rapid gametocidal activity
- B. The ability to prevent further development of hypnozoites
- C. Rapid sporontocidal activity
- D. Rapid schizonticidal activity
Correct Answer: D
Rationale: The correct answer is D: Rapid schizonticidal activity. Artemisinin and its derivatives target the asexual stage of the malaria parasite's life cycle, specifically the schizont stage. By quickly destroying the schizonts, they effectively kill the parasites in the blood, leading to a rapid reduction in parasite load and alleviating symptoms. The other choices are incorrect because A (Rapid gametocidal activity) targets sexual stage parasites, B (Ability to prevent further development of hypnozoites) refers to relapse prevention in Plasmodium vivax and Plasmodium ovale infections, and C (Rapid sporontocidal activity) targets the mosquito stage of the parasite's life cycle.
A 35-year-old male is admitted to the hospital complaining of severe headaches, vomiting, and testicular pain. His blood work shows reduced numbers of platelets, leukocytes, and erythrocytes, with a high proportion of immature cells. The nurse caring for this patient suspects a diagnosis of what?
- A. AML
- B. CML
- C. MDS
- D. ALL
Correct Answer: D
Rationale: The correct answer is D: ALL (Acute Lymphoblastic Leukemia). In this case, the patient's symptoms of severe headaches, vomiting, testicular pain, reduced blood cell counts, and high proportion of immature cells indicate a rapidly progressing hematologic malignancy affecting lymphoid cells. AML (Choice A) primarily affects myeloid cells, not lymphoid cells. CML (Choice B) is a chronic myeloid disorder and presents differently with elevated leukocyte count and mature cells. MDS (Choice C) is a group of disorders characterized by abnormal blood cell production, but the presentation in this patient is more indicative of an acute leukemia.
Cooley's anemia is:
- A. Sickle cell an.
- B. thalassemia major
- C. high ESR
- D. aplastic an.
Correct Answer: B
Rationale: Step 1: Cooley's anemia is another term for thalassemia major, a genetic disorder affecting hemoglobin production.
Step 2: Thalassemia major results in severe anemia due to the body's inability to produce enough functional hemoglobin.
Step 3: Sickle cell anemia (Choice A) is a different genetic disorder characterized by abnormal hemoglobin shape.
Step 4: High ESR (Choice C) is a non-specific marker of inflammation, not specific to Cooley's anemia.
Step 5: Aplastic anemia (Choice D) is a condition where the bone marrow does not produce enough blood cells, not specific to Cooley's anemia.
Waldeyer's ring does not include:
- A. faucal tonsils
- B. submandibular glands
- C. adenoids
- D. lingual tonsils
Correct Answer: B
Rationale: The correct answer is B: submandibular glands. Waldeyer's ring consists of a ring of lymphoid tissue in the pharynx, including the palatine tonsils (faucal tonsils), adenoids, and lingual tonsils. Submandibular glands are salivary glands located beneath the mandible and are not part of Waldeyer's ring. Therefore, B is the correct answer. Choices A, C, and D are incorrect because they are all components of Waldeyer's ring.
