1. A nurse is caring for a client diagnosed with iron-deficiency
anemia. Which laboratory value would the nurse expect to be
decreased?
A. Hemoglobin B. Platelet count C. White blood cell count D.
Sodium level
Answer: A. Hemoglobin
Rationale: Iron-deficiency anemia results in reduced hemoglobin
production because iron is essential for oxygen-carrying red blood
cells. Low hemoglobin is a key finding in anemia. Platelet and sodium
levels are not directly affected by iron deficiency, and white blood cell
counts are usually normal.
2. A client with pernicious anemia is prescribed vitamin B12
injections. What is the primary reason for this treatment?
A. To increase iron absorption B. To stimulate platelet production
C. To replace vitamin B12 deficiency D. To prevent dehydration
,Answer: C. To replace vitamin B12 deficiency
Rationale: Pernicious anemia occurs because the body cannot absorb
vitamin B12 due to lack of intrinsic factor. Vitamin B12 injections
bypass the gastrointestinal tract and restore normal red blood cell
production. Iron absorption and hydration are unrelated to the
primary cause.
3. Which assessment finding is most characteristic of sickle cell
anemia?
A. Bradycardia B. Joint pain crises C. Weight gain D. Hypertension
Answer: B. Joint pain crises
Rationale: Sickle cell anemia causes vaso-occlusion, leading to severe
pain crises, especially in the joints and bones. Bradycardia, weight
gain, and hypertension are not hallmark findings of the disease.
4. A nurse is teaching a client with neutropenia about infection
prevention. Which statement by the client indicates
understanding?
A. “I will avoid fresh flowers.” B. “I can eat raw seafood safely.” C.
“I should avoid handwashing.” D. “I do not need to avoid crowds.”
Answer: A. “I will avoid fresh flowers.”
Rationale: Fresh flowers and plants can harbor microorganisms that
increase infection risk in neutropenic clients. Handwashing, avoiding
crowds, and avoiding raw foods are also essential preventive measures.
5. Which laboratory result is most concerning in a client
receiving chemotherapy?
A. Platelets 250,000/mm3 B. White blood cells 1,000/mm3 C.
Hemoglobin 14 g/dL D. Potassium 4.0 mEq/L
, Answer: B. White blood cells 1,000/mm3
Rationale: A severely decreased white blood cell count places the client
at high risk for infection. The other values are within normal ranges.
6. A client with hemophilia is admitted after a fall. Which
nursing action is the priority?
A. Encourage ambulation B. Apply pressure to bleeding areas C.
Limit fluid intake D. Administer aspirin
Answer: B. Apply pressure to bleeding areas
Rationale: Hemophilia impairs blood clotting, increasing bleeding
risk. Applying pressure helps control hemorrhage. Aspirin should be
avoided because it increases bleeding risk.
7. Which food should the nurse recommend for a client with iron-
deficiency anemia?
A. White bread B. Applesauce C. Spinach D. Rice cakes
Answer: C. Spinach
Rationale: Spinach is rich in iron and supports hemoglobin
production. White bread, applesauce, and rice cakes contain minimal
iron.
8. A client with thrombocytopenia should avoid which activity?
A. Using a soft toothbrush B. Blowing the nose forcefully C.
Drinking fluids D. Walking daily
Answer: B. Blowing the nose forcefully
Rationale: Thrombocytopenia increases bleeding risk. Forceful nose
blowing can cause bleeding. Soft toothbrushes and safe ambulation
are encouraged.
