1. The nurse reviews the laboratory test results of a patient admitted with abdominal pain. Which information will be most important for the nurse to communicate to the health care provider?
- A. Monocytes 4%
- B. Hemoglobin 13.6 g/dL
- C. Platelet count 168,000/μL
- D. White blood cell (WBC) count 15,500/μL
Correct answer: A
Rationale: The correct answer is A. A low percentage of monocytes can indicate a viral infection. This is crucial information to communicate as it suggests a specific type of infection that may require targeted treatment. Choices B, C, and D do not directly relate to an infectious process and are within normal ranges, so they are not as urgent to communicate to the healthcare provider in this context.
2. A patient who is receiving methotrexate for severe rheumatoid arthritis develops a megaloblastic anemia. The nurse will anticipate teaching the patient about increasing oral intake of
- A. iron.
- B. folic acid.
- C. cobalamin (vitamin B12).
- D. ascorbic acid (vitamin C).
Correct answer: C
Rationale: The correct answer is C: cobalamin (vitamin B12). Methotrexate can lead to a deficiency in cobalamin, resulting in megaloblastic anemia. Therefore, increasing the oral intake of cobalamin is essential to address this deficiency. Choice A, iron, is incorrect because megaloblastic anemia caused by methotrexate is not typically due to iron deficiency. Choice B, folic acid, is also incorrect as methotrexate does not directly cause folic acid deficiency. Choice D, ascorbic acid (vitamin C), is incorrect as it is not directly related to megaloblastic anemia caused by methotrexate; instead, cobalamin is the key vitamin that needs attention.
3. The nurse assesses a patient who has numerous petechiae on both arms. Which question should the nurse ask the patient?
- A. Are you taking any oral contraceptives?
- B. Have you been prescribed antiseizure drugs?
- C. Do you take medication containing salicylates?
- D. How long have you been taking antihypertensive drugs?
Correct answer: C
Rationale: The correct answer is C: 'Do you take medication containing salicylates?' Petechiae are tiny, pinpoint, red or purple spots on the skin due to bleeding under the skin. Salicylates, which are found in medications like aspirin, interfere with platelet function and can lead to petechiae and ecchymoses. Asking about salicylate-containing medications is crucial in this situation. Choices A, B, and D are incorrect because they are not directly related to the development of petechiae.
4. A 62-year-old man with chronic anemia is experiencing increased fatigue and occasional palpitations at rest. The nurse would expect the patient's laboratory test findings to include
- A. an RBC count of 4,500,000/μL.
- B. a hematocrit (Hct) value of 38%.
- C. normal red blood cell (RBC) indices.
- D. a hemoglobin (Hgb) of 8.6 g/dL.
Correct answer: B
Rationale: The correct answer is B. In chronic anemia, the hematocrit (Hct) value is a crucial indicator of the proportion of red blood cells in the blood. A hematocrit value of 38% indicates a lower than normal level of red blood cells, which aligns with the patient's symptoms of fatigue and palpitations. Choices A, C, and D are incorrect because a low RBC count, normal RBC indices, and a hemoglobin level of 8.6 g/dL do not specifically address the decreased red blood cell mass associated with chronic anemia.
5. Which assessment finding should the nurse caring for a patient with thrombocytopenia communicate immediately to the healthcare provider?
- A. The platelet count is 52,000/µL
- B. The patient is difficult to arouse
- C. There are purpura on the oral mucosa
- D. There are large bruises on the patient's back
Correct answer: B
Rationale: The correct answer is B. Difficulty in arousing the patient may indicate a cerebral hemorrhage, which is life-threatening and requires immediate action. While a low platelet count (choice A) is concerning in thrombocytopenia, it does not require immediate communication unless accompanied by active bleeding or other critical symptoms. Purpura on the oral mucosa (choice C) and large bruises on the patient's back (choice D) are important findings in thrombocytopenia but do not indicate an immediate life-threatening situation like a possible cerebral hemorrhage.
