Nursing Elites

1. A 3-year-old boy is brought to the emergency center with dysphagia, drooling, a fever of 102°F, and stridor. Which intervention should the nurse implement first?

• A. Place the child in a mist tent
• B. Obtain a sputum culture
• C. Prepare for an emergent tracheostomy
• D. Examine the child's oropharynx and report the findings to the healthcare provider

Correct answer: A

Rationale: In a 3-year-old boy presenting with dysphagia, drooling, fever, and stridor, the priority intervention should be to place the child in a mist tent. This intervention helps alleviate respiratory distress, providing immediate relief. Options B, C, and D are not as urgent as ensuring the child's airway is managed effectively. Obtaining a sputum culture, preparing for a tracheostomy, and examining the oropharynx can be done after stabilizing the child's respiratory status.

2. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

3. Which client requires careful nursing assessment for signs and symptoms of hypomagnesaemia?

• A. A young adult client with intractable vomiting due to food poisoning
• B. A client who developed hyperparathyroidism in late adolescence
• C. A middle-aged male client in renal failure following an unsuccessful kidney transplant
• D. A female client who excessively consumes simple carbohydrates

Correct answer: C

Rationale: The correct answer is C. Clients in renal failure are at high risk for hypomagnesemia due to their impaired kidney function. Renal failure can lead to decreased excretion of magnesium, resulting in its buildup in the body and potential hypomagnesemia. This client requires careful nursing assessment for signs and symptoms of hypomagnesemia to prevent complications. Choices A, B, and D are not as directly associated with renal failure and its impact on magnesium levels. Intractable vomiting, hyperparathyroidism, and excessive consumption of simple carbohydrates may have other health implications but are not as strongly linked to hypomagnesemia as renal failure.

4. The nurse is administering total parenteral nutrition (TPN) via a central line at 75 ml/hour to a client who had a bowel resection 4 days ago. Which laboratory finding requires the most immediate intervention by the nurse?

• A. Blood glucose of 140 mg/dL
• B. White blood cell count of 8000/mm³
• C. Serum potassium of 3.8 mEq/L
• D. Serum calcium of 7.8 mg/dL

Correct answer: D

Rationale: The correct answer is D. A serum calcium level of 7.8 mg/dL requires immediate intervention due to the risk of hypocalcemia. Hypocalcemia can lead to serious complications such as tetany, seizures, and cardiac arrhythmias. The other laboratory findings are within normal limits or slightly elevated, which do not pose an immediate threat to the client's health in this scenario.

5. The healthcare provider prescribes a diet high in vitamin C for a client with a leg wound. Which food should the nurse encourage the client to eat?

• A. Bananas and pineapple
• B. Cottage cheese and crackers
• C. Peanut butter and jelly
• D. Tomato and lettuce salad

Correct answer: D

Rationale: Tomatoes and lettuce are high in vitamin C, making them suitable choices for a diet prescribed for wound healing. Bananas and pineapple (Choice A) are not particularly high in vitamin C compared to tomatoes and lettuce. Cottage cheese and crackers (Choice B) as well as peanut butter and jelly (Choice C) do not provide significant amounts of vitamin C, which is essential for wound healing.
