Kaplan NCLEX Question of The Day
1. How can a nurse recognize that a chronic renal failure client's AV shunt is patent?
- A. Absence of a bruit
- B. Presence of a thrill
- C. Blood return from the shunt
- D. Urine output greater than 30 ml/hr
Correct answer: B
Rationale: The correct assessment to determine the patency of an AV shunt in a chronic renal failure client is the presence of a thrill. A thrill is a vibration or buzzing sensation felt over the shunt site, indicating good blood flow through the shunt. While the presence of a bruit is also important for assessing an AV shunt, a thrill is a more specific indicator of patency. Blood return from the shunt is related to cannulation and not necessarily an indicator of patency. Urine output greater than 30 ml/hr is not directly related to the assessment of an AV shunt's patency.
2. When teaching a client about anti-retroviral therapy for human immunodeficiency virus (HIV), the PN should emphasize:
- A. When started, therapy must not be interrupted to prevent viral resistance.
- B. When started, therapy must not be interrupted to prevent opportunistic infection.
- C. Therapy should not be interrupted for one day each month to prevent toxicity.
- D. Therapy should not be interrupted for one week every three months to prevent toxicity.
Correct answer: A
Rationale: When teaching a client about anti-retroviral therapy for HIV, it is crucial to emphasize that therapy must not be interrupted to prevent viral resistance. HIV mutates rapidly, and any interruption can lead to the emergence of resistant strains, compromising treatment effectiveness. Choice B is incorrect because keeping the virus in check with anti-retrovirals helps the client's immune system fight off opportunistic infections. Choices C and D are incorrect because therapy should not be interrupted for any reason. If toxicity occurs, the healthcare provider may adjust the treatment regimen by prescribing alternative anti-retroviral drugs.
3. The anemias most often associated with pregnancy are:
- A. folic acid and iron deficiency.
- B. folic acid deficiency and thalassemia.
- C. iron deficiency and thalassemia.
- D. thalassemia and B12 deficiency.
Correct answer: B
Rationale: Folic acid and iron deficiency anemia are the most common types of anemia associated with pregnancy. Approximately 50% of pregnant women experience this type of anemia. Iron deficiency anemia during pregnancy typically results from the increased plasma volume, rather than a decrease in iron levels. Moreover, if a woman has iron deficiency anemia before pregnancy, it often worsens during pregnancy. Folic acid deficiency is also prevalent during pregnancy due to the increased demand for this nutrient to support fetal development. Thalassemia and B12 deficiency, while types of anemia, are not as commonly associated with pregnancy compared to folic acid and iron deficiency anemia, making them incorrect choices in this context.
4. A client has a 10% dextrose in water IV solution running. He is scheduled to receive his antiepileptic drug, phenytoin (Dilantin), at this time. The nurse knows that the phenytoin:
- A. is given after the D10W is finished.
- B. should be given at the time it is due in the medication port closest to the client.
- C. can be piggybacked into the D10W solution now.
- D. is incompatible with dextrose solutions.
Correct answer: D
Rationale: Phenytoin is incompatible with dextrose solutions as they will precipitate when mixed together. Therefore, it should not be piggybacked into the D10W solution or given through the same port. Instead, normal saline should be used to flush before and after administering phenytoin to prevent any interaction with the dextrose solution. Delaying the administration of an antiepileptic drug like phenytoin to maintain therapeutic blood levels is not recommended, so it should not be given after the D10W is finished or based on the medication port closest to the client. Choice A is incorrect because administering phenytoin after the D10W is finished is not the correct approach due to the incompatibility with dextrose solutions. Choice B is incorrect as the timing of phenytoin administration should not be based on the medication port closest to the client but on compatibility considerations. Choice C is incorrect as piggybacking phenytoin into the D10W solution is not advisable due to the incompatibility issue.
5. The newborn nursery is filled to capacity. Which newborn should the nurse assess first?
- A. A three-hour-old just waking up after a period of sleep
- B. A two-day-old crying loudly
- C. A three-day-old two hours after circumcision
- D. A one-hour-old sucking his fist
Correct answer: A
Rationale: The most critical time for assessment in a newborn is during the second period of reactivity, which occurs approximately 3-5 hours after delivery. During this phase, newborns are more likely to gag on mucus and aspirate, making it crucial for the nurse to assess their respiratory status first. Choice A indicates a newborn in this critical phase, requiring immediate assessment for potential airway compromise or respiratory distress. Choices B, C, and D do not present an immediate need for assessment related to airway compromise or respiratory distress.
