Extract:
Question 1 of 5
The nurse is reviewing laboratory values for a female patient and notes a hemoglobin level of 8.2 g/100 mL (12-16) and a hematocrit level of 21% (37% -47%). These levels are found in patients with which condition?
Correct Answer: B
Rationale: Low hemoglobin and hematocrit indicate anemia, which can result from blood loss, iron deficiency, or chronic disease. Thyroid disease, bronchitis, and hemochromatosis do not directly cause these findings.
Question 2 of 5
The nurse is assessing a patient in a family practice clinic. The patient had extensive testing to rule out Hodgkin disease. Which of the following characteristics would indicate Hodgkin disease?
Correct Answer: A
Rationale: Reed-Sternberg cells are the hallmark of Hodgkin disease, confirming its diagnosis. Cyanosis, thirst/hunger, and the Philadelphia chromosome (linked to CML) are unrelated.
Question 3 of 5
The nurse is assisting in the development of a care plan for a patient with pernicious anemia. Which of the following would be the most common nursing diagnosis with this medical condition?
Correct Answer: A
Rationale: Pernicious anemia causes vitamin B12 deficiency, reducing oxygen transport and leading to tissue hypoxia, which results in activity intolerance. Airway clearance, infection risk, and chronic pain are less directly related.
Question 4 of 5
A nurse is preparing to administer 1,000 mL of lactated Ringer's IV over 6 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 28
Rationale: Flow rate = (
Total volume × Drop factor) ÷ Time in minutes = (1000 mL × 10 gtt/mL) ÷ 360 min = 27.78 ≈ 28 gtt/min. This calculation ensures the correct infusion rate for the IV fluid.
Question 5 of 5
A nurse is planning care for a client who is to receive one unit of packed RBCs. Within which of the following time spans must the nurse complete the infusion?
Correct Answer: D
Rationale: A unit of packed RBCs must be transfused within 4 hours to minimize the risk of bacterial contamination and ensure patient safety. Longer durations increase infection risk, and 2 hours is unnecessarily restrictive.
