A nurse is reviewing the laboratory values of four clients. Which of the following values indicates to the nurse that a client has iron-deficiency anemia?
A client whose hematocrit is 42%
A client whose hemoglobin is 15 g/dL
A client whose ferritin level is 8 ng/mL
A client whose RBC count is 5.2 million/mm3
The Correct Answer is C
Iron-deficiency anemia is characterized by a deficiency of iron, which is necessary for the production of hemoglobin in red blood cells. Ferritin is a protein that stores iron in the body, and a low ferritin level is an indicator of depleted iron stores.
Ferritin: The normal range for ferritin varies depending on the laboratory, but typically it is around 12 to 300 ng/mL for females and 12 to 500 ng/mL for males. A client with a ferritin level of 8 ng/mL has a significantly low level, suggesting iron-deficiency anemia due to depleted iron stores.
Hematocrit: The normal range for hematocrit is around 36% to 46% for females and 38% to 50% for males. A client with a hematocrit of 42% falls within the normal range and does not suggest iron-deficiency anemia.
Hemoglobin: The normal range for hemoglobin is approximately 12 to 16 g/dL for females and
13.5 to 17.5 g/dL for males. A client with a hemoglobin level of 15 g/dL is within the normal range and does not indicate iron-deficiency anemia.
RBC count: The normal range for red blood cell (RBC) count is roughly 4.2 to 5.4 million/mm3 for females and 4.7 to 6.1 million/mm3 for males. A client with an RBC count of 5.2 million/mm3 falls within the normal range and does not indicate iron-deficiency anemia.

Correct Answer is A
Explanation
Iron deficiency can have various manifestations, but one of the significant effects is its impact on cognitive function. Iron is essential for the proper functioning of the brain and nervous system. In children, iron deficiency can lead to lowered intellectual performance, including difficulties with concentration, learning, memory, and problem-solving skills. It can also affect overall cognitive development and academic performance.
The other options listed are not typically associated with iron deficiency:
"Elevated temperature": Elevated temperature or fever is not a direct manifestation of iron deficiency. Fever is commonly associated with infections, inflammatory conditions, or other illnesses, but not specifically with iron deficiency.
"Decreased sleeping time": While iron deficiency can cause various symptoms, changes in sleep patterns, such as decreased sleeping time, are not a typical manifestation. Iron deficiency may cause fatigue and general weakness, which could potentially impact sleep quality and duration, but it is not directly associated with decreased sleeping time.
"Increased risk of infection": Iron deficiency can affect the immune system, making individuals more susceptible to infections. However, an increased risk of infection is a consequence of impaired immune function rather than a direct manifestation of iron deficiency itself.
Correct Answer is D
Explanation
