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. Which of the following interventions is considered the most effective form of universal precautions?

• A. Cap all used needles before removing them from their syringes
• B. Discard all used uncapped needles and syringes in an impenetrable protective container
• C. Wear gloves when administering IM injections
• D. Follow enteric precautions

Correct answer: B

Rationale: The most effective form of universal precautions is to discard all used uncapped needles and syringes in an impenetrable protective container. This practice minimizes the risk of needle-stick injuries, which are a significant concern when dealing with used needles. By safely disposing of uncapped needles, healthcare providers can protect themselves and others from potential exposure to bloodborne pathogens.

3. Before rigor mortis occurs, what is the nurse responsible for?

• A. Providing a complete bath and dressing change
• B. Placing one pillow under the body’s head and shoulders
• C. Removing the body’s clothing and wrapping the body in a shroud
• D. Allowing the body to relax normally

Correct answer: B

Rationale: Before rigor mortis occurs, the nurse is responsible for placing a pillow under the body's head and shoulders. This action helps maintain proper positioning, prevent postmortem changes, and ensure a dignified appearance. Providing a complete bath and dressing change, removing clothing, or wrapping the body in a shroud are tasks typically performed after rigor mortis sets in or later in the postmortem care process. Allowing the body to relax normally does not address the immediate need for proper positioning before rigor mortis occurs.

4. 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.

5. While teaching a newly hired nurse about varicella, a nurse in a pediatric clinic should include which of the following information?

• A. Children who have varicella are contagious until vesicles are crusted.
• B. Children who have varicella should receive the varicella (chickenpox) vaccine.
• C. Children who have varicella should be placed in airborne precautions.
• D. Children who have varicella are contagious 1-2 days before the rash appears.

Correct answer: A

Rationale: Children with varicella (chickenpox) are contagious until all vesicles are crusted over. The contagious period starts 1-2 days before the rash appears and continues until all lesions are dried and crusted. It is important to educate healthcare providers about the contagious period to prevent the spread of the virus to susceptible individuals.
