Nursing Elites

1. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

2. The healthcare provider is reviewing the lab results of a patient who has presented in the Emergency Room. The lab results show that the troponin T value is at 5.3 ng/mL. Which of these interventions, if not already completed, would take priority over the others?

• A. Place the patient in a 90-degree position
• B. Assess whether the patient is taking diuretics
• C. Obtain and attach defibrillator leads
• D. Assess the patient's last ejection fraction

Correct answer: C

Rationale: In this scenario, the elevated Troponin T level indicates cardiac damage, possibly due to a myocardial infarction. A Troponin T value of 5.3 ng/mL is significantly elevated (normal levels are below 0.2 ng/mL), suggesting acute cardiac injury. Given the setting of an Emergency Room and the critical nature of the situation, the priority intervention should be to obtain and attach defibrillator leads. Elevated Troponin T levels can indicate a higher risk of arrhythmias, including ventricular fibrillation, which can lead to sudden cardiac arrest. Defibrillator leads are essential for monitoring the patient's cardiac rhythm and readiness for immediate defibrillation if necessary. Placing the patient in a 90-degree position (Choice A) or assessing diuretic use (Choice B) are not immediate priorities in this critical situation. Additionally, assessing the patient's last ejection fraction (Choice D) is important but not as urgent as preparing for potential life-threatening arrhythmias requiring defibrillation.

3. While planning care for a 2-year-old hospitalized child, which situation would the nurse expect to most likely affect the behavior?

• A. Strange bed and surroundings
• B. Separation from parents
• C. Presence of other toddlers
• D. Unfamiliar toys and games

Correct answer: B

Rationale: The correct answer is 'Separation from parents.' Separation anxiety is most evident from 6 months to 30 months of age and is the greatest stress imposed on a toddler by hospitalization. If separation is avoided, young children have a tremendous capacity to withstand other stress. The other choices, such as 'Strange bed and surroundings,' 'Presence of other toddlers,' and 'Unfamiliar toys and games,' may also have an impact on the child, but separation from parents is typically the most significant factor affecting behavior in a hospitalized 2-year-old.

4. An 18-month-old child is being discharged after surgical repair of hypospadias. Which postoperative nursing care measure should the nurse stress to the parents as they prepare to take their child home?

• A. Leave the diapers on to protect the surgical site.
• B. Avoid tub baths until the stent has been removed.
• C. Delay toilet training until the child has fully recovered.
• D. Encourage adequate fluid intake to maintain hydration.

Correct answer: B

Rationale: After surgical repair of hypospadias, the nurse should stress to the parents to avoid giving the child a tub bath until the stent has been removed. This precaution helps prevent infection and ensures proper healing of the surgical site. Leaving diapers on is important to protect the surgical site from contamination. Delaying toilet training is recommended to reduce stress on the child during the recovery period. Encouraging adequate fluid intake is crucial to maintain hydration and support the healing process.

5. What nursing action demonstrates the nurse understands the priority nursing diagnosis when caring for patients being treated with splints, casts, or traction?

• A. The nurse assesses extremity pulse, temperature, color, pain, and feeling every hour.
• B. The nurse orders meals with adequate protein and calcium for the patient.
• C. The nurse teaches the patient never to insert objects under a cast to scratch an itch.
• D. The nurse administers oral painkillers as ordered.

Correct answer: A

Rationale: The correct answer is to assess extremity pulse, temperature, color, pain, and feeling every hour. This action aligns with the priority nursing diagnosis of Risk for Peripheral Neurovascular Dysfunction related to fractures. Monitoring these factors is crucial to detect any signs of compromised circulation or nerve function promptly. Option B is incorrect as it does not directly address the priority nursing diagnosis. Option C is important but does not directly relate to the neurovascular aspect. Option D, administering painkillers, is necessary but does not specifically address the priority nursing diagnosis of neurovascular dysfunction.
