Nursing Elites

1. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?

• A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
• B. Circulatory overload due to hypervolemia
• C. Respiratory excitement
• D. Inhibition of the respiratory hypoxic stimulus

Correct answer: D

Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.

2. When planning care for a client on mechanical ventilation, which mode of ventilation that increases the effort of the client's respiratory muscles should NOT be included in the plan of care?

• A. Assist-control
• B. Synchronized intermittent mandatory ventilation
• C. Continuous positive airway pressure
• D. Pressure support ventilation

Correct answer: A

Rationale: Assist-control ventilation mode delivers a preset tidal volume at a set rate; however, it may not be suitable for clients who need to maintain some level of respiratory muscle activity. This mode provides full support for each breath, potentially leading to decreased respiratory muscle strength over time. Therefore, it is important to avoid using assist-control mode for clients who require increased effort of respiratory muscles to prevent muscle atrophy and promote optimal respiratory function.

3. When providing discharge teaching for a group of clients, a nurse should recommend a referral to a dietitian for which client?

• A. A client who has a prescription for warfarin and states, 'I will need to limit how much spinach I eat.'
• B. A client who has gout and states, 'I can continue to eat anchovies on my pizza.'
• C. A client who has a prescription for spironolactone and states, 'I will reduce my intake of foods that contain potassium.'
• D. A client who has osteoporosis and states, 'I'll plan to take my calcium carbonate with a full glass of water.'

Correct answer: B

Rationale: The correct answer is the client who has gout and states, 'I can continue to eat anchovies on my pizza.' Gout is a condition that requires dietary modifications to manage symptoms. Anchovies are high in purines, which can exacerbate gout symptoms. Therefore, a referral to a dietitian is essential to provide appropriate dietary guidance for a client with gout. Clients on warfarin may need to monitor their vitamin K intake, particularly from foods like spinach. Clients taking spironolactone should be cautious about potassium-rich foods. Clients with osteoporosis should be educated on the proper administration of calcium supplements but do not necessarily need a dietitian referral for this specific statement.

4. A caregiver is caring for a 5-month-old infant who has manifestations of severe dehydration and a prescription for parenteral fluid therapy. The caregiver asks, 'What are the indications that my baby needs an IV?' Which of the following responses should the caregiver make?

• A. Your baby needs an IV because she is not producing any tears
• B. Your baby needs an IV because her fontanels are bulging
• C. Your baby needs an IV because she is breathing slower than normal
• D. Your baby needs an IV because her heart rate is decreasing

Correct answer: A

Rationale: The correct response is A: 'Your baby needs an IV because she is not producing any tears.' In infants, the inability to produce tears is a sign of severe dehydration. This is a crucial indication for the need for intravenous (IV) fluid therapy to rehydrate the infant. While the other options may also be symptoms of dehydration, the absence of tears is a more direct and specific indicator requiring immediate attention and intervention.

5. A healthcare professional is reviewing the health records of five clients. Which of the following clients is not at risk for developing acute respiratory distress syndrome?

• A. A client who experienced a near-drowning incident
• B. A client following coronary artery bypass graft surgery
• C. A client who has a hemoglobin of 15.1 g/dL
• D. A client who has dysphagia

Correct answer: C

Rationale: Acute respiratory distress syndrome (ARDS) is a severe lung condition that can be triggered by various factors such as near-drowning incidents, surgeries like coronary artery bypass graft, and underlying conditions like dysphagia. Hemoglobin levels do not directly influence the risk of developing ARDS. A hemoglobin level of 15.1 g/dL falls within the normal range and does not predispose an individual to ARDS.
