1. A healthcare provider reviews the laboratory data for an older patient. The healthcare provider would be most concerned about which finding?
- A. Hematocrit of 35%
- B. Hemoglobin of 11.8 g/dL
- C. Platelet count of 400,000/μL
- D. White blood cell (WBC) count of 2800/μL
Correct answer: D
Rationale: A low white blood cell (WBC) count in an older patient is concerning as it indicates a potential compromise in the patient's immune function. White blood cells are crucial for fighting infections and a low count could lead to an increased risk of infections. Hematocrit, hemoglobin, and platelet count are important parameters to assess, but a low WBC count takes priority in this case due to its direct impact on immune health.
2. The nurse notes scleral jaundice in a patient being admitted with hemolytic anemia. The nurse will plan to check the laboratory results for the
- A. Schilling test
- B. bilirubin level
- C. gastric analysis
- D. stool occult blood
Correct answer: B
Rationale: The correct answer is B: bilirubin level. Jaundice, characterized by scleral jaundice, is caused by the elevation of bilirubin levels associated with red blood cell hemolysis. Checking the bilirubin level in the laboratory results will help assess the severity of jaundice in the patient. Choices A, C, and D are incorrect because the Schilling test is used to assess vitamin B12 absorption, gastric analysis is used to evaluate gastric function, and stool occult blood is used to detect hidden blood in the stool, which are not directly related to evaluating jaundice in a patient with hemolytic anemia.
3. A patient who had a total hip replacement had an intraoperative hemorrhage 14 hours ago. Which laboratory test result would the nurse expect?
- A. Hematocrit of 46%
- B. Hemoglobin of 13.8 g/dL
- C. Elevated reticulocyte count
- D. Decreased white blood cell (WBC) count
Correct answer: C
Rationale: The correct answer is C: Elevated reticulocyte count. Hemorrhage leads to the release of reticulocytes (immature red blood cells) from the bone marrow into circulation as a compensatory mechanism to replenish lost red blood cells. This response helps in restoring the oxygen-carrying capacity of the blood. Choices A and B, hematocrit of 46% and hemoglobin of 13.8 g/dL, may not reflect the immediate response to hemorrhage within 14 hours. Choice D, decreased white blood cell (WBC) count, is not directly related to the body's response to hemorrhage.
4. The nurse is caring for a patient post coronary artery bypass graft who rates his/her pain as an 8 out of 10 on the subjective pain scale. Should the nurse choose to administer morphine sulfate intravenously as it has benefits to cardiac patients (select one that does not apply)?
- A. Decreasing myocardial oxygen supply
- B. Decreasing myocardial oxygen consumption
- C. Decreasing heart rate
- D. Increasing blood pressure
Correct answer: D
Rationale: Morphine sulfate, a potent opioid analgesic, can cause vasodilation leading to a decrease in blood pressure rather than an increase. Choice A is incorrect as morphine can decrease myocardial oxygen consumption by reducing the workload of the heart. Choice B is incorrect as morphine can decrease heart rate as a side effect. Choice C is incorrect as morphine typically decreases blood pressure rather than increasing it.
5. When providing care for a patient with sickle cell crisis, what is important for the nurse to do?
- A. Monitor the patient's intake of oral and IV fluids
- B. Evaluate the effectiveness of opioid analgesics
- C. Encourage the patient to ambulate as much as tolerated
- D. Educate the patient about high-protein, high-calorie foods
Correct answer: B
Rationale: The correct answer is to evaluate the effectiveness of opioid analgesics. In sickle cell crisis, pain is the most common symptom and is usually managed with large doses of continuous opioids. Monitoring fluid intake (Choice A) is important, but limiting fluids may not be necessary. Encouraging ambulation (Choice C) is generally good but may not be the priority during a sickle cell crisis. Educating the patient about nutrition (Choice D) is important for overall health but may not be the immediate focus during a crisis.
