Nursing Elites

1. 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%.

2. 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.

3. The healthcare provider is assessing a client with chronic renal failure who is receiving hemodialysis. Which of the following findings would indicate that the client is experiencing a complication of the treatment?

• A. Clear dialysate outflow.
• B. Blood pressure of 150/90 mm Hg.
• C. Increased heart rate.
• D. Fatigue.

Correct answer: B

Rationale: A blood pressure of 150/90 mm Hg during hemodialysis may indicate fluid overload or an ineffective dialysis session, which can lead to complications such as heart failure or pulmonary edema. This finding should be reported promptly for further evaluation and intervention. Clear dialysate outflow is a normal and expected finding during hemodialysis, indicating proper filtration of waste products. Increased heart rate can be a normal compensatory response to hemodialysis due to fluid shifts and should be monitored but does not necessarily indicate a complication. Fatigue is a common symptom in clients with chronic renal failure undergoing hemodialysis and is not specific to complications of the treatment.

4. A client who has undergone pleural biopsy is being monitored by a nurse. Which finding indicates a potential complication for the client?

• A. Warm, dry skin
• B. Mild pain at the biopsy site
• C. Complaints of shortness of breath
• D. Capillary refill time of less than 3 seconds

Correct answer: C

Rationale: Complaints of shortness of breath are a concerning finding post-pleural biopsy, as they may indicate a complication such as a pneumothorax or hemothorax. Shortness of breath can be a sign of respiratory distress that requires immediate attention. Warm, dry skin, mild pain at the biopsy site, and a capillary refill time of less than 3 seconds are not typically associated with immediate complications following a pleural biopsy. Warm, dry skin may be a normal finding, mild pain can be expected at the biopsy site, and a capillary refill time of less than 3 seconds is within normal limits.

5. The healthcare provider assesses a client with cirrhosis and finds 4+ pitting edema of the feet and legs, and massive ascites. Which mechanism contributes to edema and ascites in clients with cirrhosis?

• A. Hyperaldosteronism causing increased sodium transport ion in renal tubules
• B. Decreased portacaval pressure with greater collateral circulation
• C. Decreased renin-angiotensin response related to increased renal blood flow
• D. Hypoalbuminemia that results in decreased colloidal oncotic pressure

Correct answer: D

Rationale: In clients with cirrhosis, hypoalbuminemia leads to decreased colloidal oncotic pressure. This reduction in oncotic pressure contributes to the development of edema in the feet and legs (pitting edema) and ascites in the abdomen. Hyperaldosteronism (choice A) would lead to sodium retention but is not the primary mechanism behind edema and ascites in cirrhosis. Decreased portacaval pressure with greater collateral circulation (choice B) is not directly related to the pathophysiology of edema and ascites in cirrhosis. Decreased renin-angiotensin response related to increased renal blood flow (choice C) does not play a significant role in the development of edema and ascites in cirrhosis compared to the impact of hypoalbuminemia on colloidal oncotic pressure.
