A client whose hemoglobin level was 6 gm/dL 2 days ago has received parenteral epoetin alfa. A hemoglobin level has just been drawn to evaluate therapy. The nurse would consider which hemoglobin lab result as most problematic?

1. 1314 gm/dL
2. 78 gm/dL
3. 1112 gm/dL
4. 910 gm/dL

Question 2

A client who has just returned from an extended mountain-climbing trip in the Andes is seen in a clinic for an elective procedure. Preprocedure blood work reveals a very high hemoglobin level and red blood cell count.

Which action should the nurse take?
1. Ask if the client ate a lot of iron-rich raisins in trail mix on the journey.
2. Place the lab results in the chart for the health care provider to review prior to the procedure.
3. Ask if the client used supplemental oxygen during high-altitude climbing.
4. Call the lab and have the test repeated.

Answer to Question 1

Correct Answer: 1
Rationale 1: If the level exceeds 12 gm/dL, the risk of blood clots increases, which puts the client at risk for stroke and heart attack.
Rationale 2: Epoetin alfa therapy is given to increase the hemoglobin and hematocrit. This reading is increasing, which is a positive outcome.
Rationale 3: A hemoglobin level of 1112 gm/dL is approaching serious levels but is still normal.
Rationale 4: A hemoglobin level of 910 gm/dL is a good level for this client.
Global Rationale: If the level exceeds 12 gm/dL, the risk of blood clots increases, which puts the client at risk for stroke and heart attack. Epoetin alfa therapy is given to increase the hemoglobin and hematocrit. This reading is increasing, which is a positive outcome. A hemoglobin level of 1112 gm/dL is approaching serious levels but is still normal. A hemoglobin level of 910 gm/dL is a good level for this client.

Answer to Question 2

Correct Answer: 2
Rationale 1: Raisins are high in iron, and iron is necessary to form the hemoglobin molecule. A high iron level by itself would not increase the red cell count or elevate the hemoglobin level.
Rationale 2: Chronic hypoxia at high altitudes increases the red blood cell count and the hemoglobin level. These levels are compensatory changes that allow the blood to carry more oxygen to the cells.
Rationale 3: Supplemental oxygen is necessary at high altitudes because the amount of oxygen is insufficient to meet a climber's needs. Supplemental oxygen tends to decrease erythropoietin production.
Rationale 4: There is no need to have the test repeated, as this value is probably correct.
