Question 1 of 5
The mother of a one-year-old with sickle cell anemia wants to know why the condition didn't show up in the nursery. The nurse's response is based on the knowledge that:
Correct Answer: D
Rationale: Fetal hemoglobin (HbF), predominant in newborns, inhibits sickling in sickle cell anemia, delaying symptoms until HbF decreases around 6 months. Newborn screening exists, and infections can trigger crises later.
Question 2 of 5
A patient with thrombocytopenia has a platelet count of 80,000. It will be most important to teach the client about:
Correct Answer: A
Rationale: Thrombocytopenia (low platelet count) increases bleeding risk. Teaching measures to reduce bleeding (e.g. avoiding trauma using soft toothbrushes) is critical. Fluid intake oxygenation and energy conservation are less directly related to the condition.
Question 3 of 5
A client has been taking lithium 300 mg po bid for the past two weeks. This morning her lithium level was 1 mEq/L. The nurse should:
Correct Answer: C
Rationale: There is no need to phone the physician because the lithium level is within therapeutic range and because there are no indications of toxicity present. There is no reason to withhold the lithium because the blood level is within therapeutic range. Also, it is necessary to give the medication as scheduled to maintain adequate blood levels. The lab results indicate that the client's lithium level is within therapeutic range (0.2-1.4 mEq/L), so the medication should be given as ordered. Benztropine is an antiparkinsonism drug frequently given to counteract extrapyramidal symptoms associated with the administration of antipsychotic drugs (not lithium).
Question 4 of 5
Which of the following risk factors associated with breast cancer would a nurse consider most significant in a client's history?
Correct Answer: C
Rationale: Women who begin menarche late (after 13 years old) have a lower risk of developing breast cancer than women who have begun earlier. Average age for menarche is 12.5 years. Women who have never been pregnant have an increased risk for breast cancer, but a positive family history poses an even greater risk. A positive family history puts a woman at an increased risk of developing breast cancer. It is recommended that mammography screening begin 5 years before the age at which an immediate female relative was diagnosed with breast cancer. Early menopause decreases the risk of developing breast cancer.
Question 5 of 5
A client is experiencing visual problems at school. She has complained of difficulty seeing the blackboard and squinting. She no longer likes to participate in physical activities such as softball. The client has displayed possible classic symptoms of which refractive error?
Correct Answer: C
Rationale: Visual images are blurred and distorted. Symptoms are headaches, burning eyes, fatigue, squinting, and difficulty reading. These symptoms are classic for myopia. Amblyopia is not a refractive error. It is a loss of vision in one or both eyes.
