Nursing Elites

1. A client recently started on warfarin therapy. What laboratory value is most important to monitor for this client?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Creatinine level
• D. Blood urea nitrogen (BUN)

Correct answer: B

Rationale: Prothrombin time (PT) is the most important laboratory value to monitor for clients on warfarin therapy. PT helps determine how long it takes blood to clot and ensures the warfarin dose is within the therapeutic range to prevent either excessive bleeding or clotting. Monitoring platelet count is important for assessing the risk of bleeding, but PT is more specific to warfarin therapy. Creatinine level and BUN are indicators of kidney function and are not directly related to warfarin therapy.

2. A client with acute kidney injury (AKI) is experiencing hyperkalemia. What intervention should the nurse prioritize?

• A. Administer IV calcium gluconate.
• B. Administer sodium polystyrene sulfonate (Kayexalate).
• C. Administer insulin with dextrose.
• D. Restrict potassium intake in the client's diet.

Correct answer: A

Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.

3. A client presents to the labor and delivery unit with a report of leaking fluid that is greenish-brown vaginal discharge. Which action should the nurse take first?

• A. Notify the healthcare provider immediately
• B. Begin continuous fetal monitoring
• C. Check the amniotic fluid pH
• D. Assess maternal vital signs

Correct answer: B

Rationale: Greenish-brown discharge likely indicates meconium in the amniotic fluid, which poses a risk to the fetus. Continuous fetal monitoring should be initiated immediately to assess for signs of fetal distress. Meconium-stained amniotic fluid can lead to meconium aspiration syndrome in the newborn, so timely monitoring is crucial. Checking the amniotic fluid pH can help confirm the presence of meconium but is not the priority over fetal monitoring. Assessing maternal vital signs is important but secondary to monitoring the fetal well-being in this urgent situation. Notifying the healthcare provider can follow once the immediate fetal assessment is underway.

4. The nurse is caring for a 24-month-old toddler who has sensory sensitivity, difficulty engaging in social interactions, and has not yet spoken two-word phrases. Which assessment should the nurse administer?

• A. Peabody Picture Vocabulary Test
• B. The Modified Checklist for Autism in Toddlers (M-CHAT)
• C. Wechsler Preschool and Primary Scale of Intelligence
• D. Denver Developmental Screening Test

Correct answer: B

Rationale: The Modified Checklist for Autism in Toddlers (M-CHAT) is specifically designed to screen for autism spectrum disorders in young children. It is appropriate for this child, given the signs of social and communication delays. The Peabody Picture Vocabulary Test (Choice A) assesses receptive vocabulary and may not capture the social and communication aspects seen in autism. The Wechsler Preschool and Primary Scale of Intelligence (Choice C) measures cognitive ability and may not address the social and communication delays. The Denver Developmental Screening Test (Choice D) is a broad developmental assessment tool, but the M-CHAT is more specific to screening for autism in this case.

5. A client with a history of closed head injury has a radial artery catheter in place and complains of numbness and pain distal to the insertion site. What action should the nurse take?

• A. Monitor the site for further complications.
• B. Promptly remove the catheter from the radial artery.
• C. Elevate the client’s arm above the heart.
• D. Notify the healthcare provider and prepare for surgery.

Correct answer: B

Rationale: A weak pulse and numbness distal to a radial artery catheter may indicate occlusion or damage to the artery, and immediate removal of the catheter is necessary to prevent complications. Therefore, promptly removing the catheter from the radial artery (Choice B) is the correct action. Monitoring the site (Choice A) would delay necessary intervention, elevating the client's arm (Choice C) may not address the underlying issue, and notifying the healthcare provider for surgery (Choice D) without removing the catheter promptly could lead to further complications.
