Nursing Elites

1. A marathon runner comes into the clinic and states, 'I have not urinated very much in the last few days.' The nurse notes a heart rate of 110 beats/min and a blood pressure of 86/58 mm Hg. Which action by the nurse is the priority?

• A. Give the client a bottle of water immediately.
• B. Start an intravenous line for fluids.
• C. Teach the client to drink 2 to 3 liters of water daily.
• D. Perform an electrocardiogram.

Correct answer: A

Rationale: The priority action for the nurse is to give the client a bottle of water immediately. The athlete's symptoms of decreased urination, along with a heart rate of 110 beats/min and low blood pressure of 86/58 mm Hg, indicate mild dehydration. Rehydration should begin promptly to address the dehydration. Teaching the client to drink 2 to 3 liters of water daily is a good long-term strategy but not the immediate priority. Starting an intravenous line for fluids may be necessary if oral hydration is insufficient or if the degree of dehydration is severe. Performing an electrocardiogram is not indicated at this time as the priority is addressing the dehydration.

2. When planning care for a client newly diagnosed with open-angle glaucoma, the nurse identifies a priority nursing problem of 'visual sensory/perceptual alterations.' This problem is based on which etiology?

• A. Blurred distance vision
• B. Limited eye movement
• C. Decreased peripheral vision
• D. Photosensitivity

Correct answer: C

Rationale: The correct answer is 'C: Decreased peripheral vision.' Open-angle glaucoma leads to a gradual loss of peripheral vision due to damage to the optic nerve. This loss of peripheral vision is a hallmark sign of the condition and a primary reason for the visual sensory/perceptual alterations experienced by the client. Blurred distance vision (choice A) may occur but is not the priority nursing problem. Limited eye movement (choice B) and photosensitivity (choice D) are not typically associated with the sensory/perceptual alterations seen in open-angle glaucoma.

3. A client without a history of respiratory disease has a pulse oximeter in place after surgery. The nurse monitors the pulse oximeter readings to ensure that oxygen saturation remains above:

• A. 85%
• B. 89%
• C. 95%
• D. 100%

Correct answer: C

Rationale: Pulse oximetry is a noninvasive method of continuously monitoring the oxygen saturation of hemoglobin (SaO2). In the absence of underlying respiratory disease, the expected oxygen saturation level is at least 95%. Oxygen saturation levels below 95% may indicate hypoxemia, which can compromise tissue perfusion and oxygen delivery to vital organs. Therefore, maintaining oxygen saturation above 95% is crucial to ensure adequate oxygenation post-surgery. Choices A, B, and D are incorrect as they represent oxygen saturation levels that are below the expected value for a client without a history of respiratory disease, which should be at least 95%.

4. A client is placed on fluid restrictions because of chronic kidney disease (CKD). Which assessment finding would alert the nurse that the client’s fluid balance is stable at this time?

• A. Decreased calcium levels
• B. Increased phosphorus levels
• C. No adventitious sounds in the lungs
• D. Increased edema in the legs

Correct answer: C

Rationale: The absence of adventitious sounds upon auscultation of the lungs is a key indicator that the client's fluid balance is stable. Adventitious sounds, such as crackles or wheezes, are typically heard in conditions of fluid overload, indicating that the body is retaining excess fluid. Choices A and B, decreased calcium levels and increased phosphorus levels, are common laboratory findings associated with chronic kidney disease (CKD) and are not directly related to fluid balance. Increased edema in the legs is a sign of fluid imbalance, suggesting fluid retention in the tissues, which would not indicate stable fluid balance in a client with CKD on fluid restrictions.

5. A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client's respiratory acidosis?

• A. Carbon dioxide is converted in the kidneys for elimination.
• B. Blood oxygen levels are stimulating the respiratory rate.
• C. Hyperventilation is eliminating carbon dioxide rapidly.
• D. High levels of carbon dioxide have accumulated in the blood.

Correct answer: D

Rationale: The correct answer is D. High levels of carbon dioxide in the blood are indicative of respiratory acidosis, often due to inadequate ventilation. In respiratory acidosis, there is retention of carbon dioxide (hypercapnia) leading to an increase in carbonic acid levels in the blood, resulting in an acidic pH. Option A is incorrect because carbon dioxide elimination primarily occurs through the lungs, not the kidneys. Option B is incorrect because blood oxygen levels primarily affect the respiratory rate to regulate oxygen levels, not carbon dioxide levels. Option C is incorrect because hyperventilation would lead to a decrease, not an increase, in carbon dioxide levels.
