NCLEX-PN Exam Questions - Part 43
1. What happens if folic acid is given to treat anemia without determining its underlying cause?
A) Erythropoiesis is inhibited.
B) Excessive levels of folic acid might accumulate, causing toxicity.
C) The symptoms of pernicious anemia might be masked, delaying treatment.
D) Intrinsic factor is destroyed.
2. Which of the following should not be included in the teaching for clients who take oral iron preparations?
A) Mix the liquid iron preparation with antacids to reduce GI distress.
B) Take the iron with meals if GI distress occurs.
C) Liquid forms should be taken with a straw to avoid discoloration of tooth enamel.
D) Oral forms should be taken with juice, not milk.
3. The test used to differentiate sickle cell trait from sickle cell disease is:
A) sickle cell preparation.
B) peripheral smear.
C) sickledex.
D) hemoglobin electrophoresis.
4. While performing a physical assessment on a 6-month-old infant, the nurse observes head lag. Which of the following nursing actions should the nurse perform first?
A) Ask the parents to allow the infant to lay on her stomach to promote muscle development.
B) Notify the physician because a developmental or neurological evaluation is indicated.
C) Document the findings as normal in the nurse - s notes.
D) Explain to the parents that their child is likely to be mentally retarded.
5. A preschooler has successfully completed the test item 'counts 5 blocks' on the Denver II test. This pass is evidence of which of the following developmental concepts?
A) centration
B) causality
C) nonreversibility
D) conservation
A) Erythropoiesis is inhibited.
B) Excessive levels of folic acid might accumulate, causing toxicity.
C) The symptoms of pernicious anemia might be masked, delaying treatment.

A) centration
B) causality
C) nonreversibility
D) conservation
1. Right Answer: C
Explanation: Folic acid should not be used if pernicious anemia is suspected because it does not protect the client from CNS changes common to this type of anemia. Folic acid is usually given with Vitamin B12. Both are part of the Vitamin B complex and are essential for cell growth and division. Folic acid is sometimes used as a rescue drug for cells exposed to some toxic chemotherapeutic agents. The nature of the anemia must be confirmed to ensure that the proper drug regimen is being used. Physiological Adaptation
2. Right Answer: A
Explanation: Iron should not be mixed with antacids. Physiological Adaptation
3. Right Answer: D
Explanation: Hemoglobin electrophoresis is used to differentiate between sickle cell trait and sickle cell disease. Physiological Adaptation
4. Right Answer: B
Explanation: Head lag should be completely resolved by 4 months of age. Continuing head lag at 6 months of age indicates the need for further developmental or neurological evaluation. Laying the infant on her stomach promotes muscle development of the neck and shoulder muscles, but because of the age of this child, a referral should be the first action. These findings are not normal for a 6-month-old infant. Significant head lag can be seen in infants with Down syndrome and hypoxia, as well as neurologic and other metabolic disorders. Some of those disorders might have mental retardation as a component. However, this child needs to have the referral to determine the cause of the head lag first. Health Promotion and Maintenance
5. Right Answer: D
Explanation: The ability to move five blocks to a piece of paper and state there are five blocks on the paper is evidence that the preschooler has the ability of conservation. This concept refers to the fact that the quantity of something doesnt change just because the shape, contour, and so on has changed. Five blocks are still five blocks, whether they are lying beside the paper, stacked on the paper or moved to the paper. Centration is the ability to concentrate on one feature of a situation while neglecting all other aspects. Causality is based on the sequence of events, one event ordinarily following another. Nonreversibility refers to the inability of preschoolers to reverse their operations. They are only able to think forward, not retrace or reverse their thought processes.
