Nursing Elites

1. Which of the following are key parameters that produce blood pressure? (Select ONE that does not apply)

• A. Heart rate
• B. Stroke volume
• C. Peripheral resistance
• D. Neuroendocrine hormones

Correct answer: D

Rationale: Heart rate, stroke volume, and peripheral resistance are indeed key parameters that directly influence blood pressure. Heart rate refers to the number of times the heart beats per minute, affecting how much blood is pumped. Stroke volume is the amount of blood pumped by the heart in one contraction. Peripheral resistance is the resistance of the arteries to blood flow, impacting the pressure needed to push blood through. Neuroendocrine hormones, while they can indirectly influence blood pressure regulation by affecting factors like blood volume and vascular tone, are not direct final parameters that produce blood pressure.

2. A client is being treated for heart failure. What should the nurse monitor to evaluate treatment effectiveness?

• A. Daily weight
• B. Electrolyte levels
• C. Urine output
• D. All of the above

Correct answer: D

Rationale: Monitoring daily weight, electrolyte levels, and urine output is crucial in evaluating treatment effectiveness for heart failure. Daily weight monitoring helps assess fluid retention or loss, changes in electrolyte levels can indicate imbalances affecting heart function, and urine output monitoring provides insights into kidney function and fluid balance. Therefore, all options are essential components in assessing the patient's fluid status and response to treatment, making 'All of the above' the correct answer. Choices A, B, and C are incorrect individually as they only represent partial aspects of monitoring heart failure treatment effectiveness.

3. The nurse is assessing a client who has been diagnosed with chronic obstructive pulmonary disease (COPD). Which clinical finding is characteristic of this condition?

• A. Pursed-lip breathing
• B. Hyperresonance on percussion
• C. Bradycardia
• D. High-pitched inspiratory crackles

Correct answer: A

Rationale: Pursed-lip breathing is a characteristic finding in clients with COPD. It helps keep the airways open during exhalation, acting as a compensatory mechanism to prevent airway collapse, which is common in COPD. Hyperresonance on percussion is typically found in conditions like emphysema, which is a component of COPD but not characteristic of the overall disease. Bradycardia is not typical in COPD; instead, clients often exhibit tachycardia due to chronic hypoxemia. High-pitched inspiratory crackles are more commonly associated with conditions like pneumonia, not COPD.

4. What action should the nurse implement in caring for a client following an electroencephalogram (EEG)?

• A. Monitor the client's vital signs every 4 hours
• B. Assess the client's lower extremities for sensation
• C. Instruct the client to maintain bed rest
• D. Wash any paste from the client's hair and scalp

Correct answer: D

Rationale: The correct action the nurse should implement after an EEG is to wash any paste from the client's hair and scalp. This is crucial to prevent irritation and infection at the EEG site. Monitoring vital signs every 4 hours is not specifically indicated after an EEG. Assessing the client's lower extremities for sensation is unrelated to caring for a client post-EEG. While rest may be recommended after the procedure, there is no standard requirement for a specific duration of bed rest.

5. A client with a history of chronic obstructive pulmonary disease (COPD) is prescribed oxygen therapy at 2 liters per minute via nasal cannula. What is the most important instruction the nurse should provide?

• A. Increase the oxygen flow rate if shortness of breath occurs
• B. Use oxygen only when experiencing shortness of breath
• C. Do not adjust the oxygen flow rate without consulting a healthcare provider
• D. Use a humidifier with the oxygen to prevent dry mucous membranes

Correct answer: C

Rationale: The most important instruction the nurse should provide to a client with COPD prescribed oxygen therapy is not to adjust the oxygen flow rate without consulting a healthcare provider. This is crucial because too much oxygen can suppress the client's respiratory drive, leading to further complications. Choice A is incorrect because increasing the oxygen flow rate without medical advice can be harmful. Choice B is incorrect as oxygen therapy should be used as prescribed, not just when symptoms occur. Choice D is incorrect as the priority is to ensure the correct oxygen flow rate rather than using a humidifier.
