Nursing Elites

1. A male client admitted three days ago with respiratory failure is intubated, and 40% oxygen per facemask is initiated. Currently, his temperature is 99°F, capillary refill is less than 4 seconds, and respiratory effort is within normal limits. What outcome should the nurse evaluate to measure for successful extubation?

• A. Exhibits adequate tissue perfusion
• B. Remains free of injury
• C. Remains free of infection
• D. Maintains effective breathing pattern

Correct answer: D

Rationale: Successful extubation relies on the patient's ability to maintain an effective breathing pattern. This indicates that the patient can adequately oxygenate and ventilate without the need for mechanical support. Monitoring tissue perfusion, preventing infection, and ensuring safety are important but not directly related to the immediate criteria for successful extubation. Tissue perfusion, injury prevention, and infection control are crucial aspects of overall patient care but are not the primary factors to consider when evaluating readiness for extubation.

2. The nurse is caring for a client who is receiving total parenteral nutrition (TPN) via a central venous catheter. Which assessment finding indicates a complication related to the TPN?

• A. Blood glucose level of 180 mg/dl
• B. Serum potassium level of 4.0 mEq/L
• C. Weight gain of 2 pounds in 24 hours
• D. White blood cell count of 7000/mm3

Correct answer: C

Rationale: A weight gain of 2 pounds in 24 hours is concerning as it indicates fluid retention, a potential complication of TPN leading to fluid overload. Elevated blood glucose levels (Choice A) are expected in TPN, serum potassium levels (Choice B) are within the normal range, and a white blood cell count (Choice D) of 7000/mm3 is also normal. Therefore, the correct answer is C, as it suggests a complication related to TPN.

3. 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.

4. 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.

5. The client is being taught how to take alendronate (Fosamax) for osteoporosis treatment. Which statement indicates that the client needs further teaching?

• A. I should take this medication at bedtime
• B. I will need to take this medication for at least 3 years
• C. I should sit up for 30 minutes after taking the medication
• D. I should take this medication with a full glass of water

Correct answer: A

Rationale: The correct answer is A because taking Fosamax at bedtime is incorrect. It should be taken in the morning with a full glass of water to prevent esophageal irritation. Choice B is correct; alendronate is typically taken for several years to treat osteoporosis. Choice C is correct as remaining upright for 30 minutes after taking Fosamax helps prevent esophageal irritation. Choice D is also correct as taking alendronate with a full glass of water is necessary to ensure proper absorption.
