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. An emergency department nurse assesses a client with kidney trauma and notes that the client’s abdomen is tender and distended, and blood is visible at the urinary meatus. Which prescription should the nurse consult the provider about before implementation?

• A. Assessing vital signs every 15 minutes
• B. Inserting an indwelling urinary catheter
• C. Administering intravenous fluids at 125 mL/hr
• D. Typing and crossmatching for blood products

Correct answer: B

Rationale: In a client with kidney trauma and blood visible at the urinary meatus, inserting a urinary catheter via the urethra should be avoided until further diagnostic studies are completed to prevent potential urethral tears. The nurse should consult the provider about the need for a catheter; if necessary, a suprapubic catheter can be used instead. Assessing vital signs every 15 minutes is important for continuous monitoring of the client's condition. Administering intravenous fluids at 125 mL/hr is crucial to maintain hydration and support kidney function. Typing and crossmatching for blood products is necessary in case the client requires blood transfusion due to potential blood loss from the trauma.

3. The nurse empties the nasogastric suction collection canister of a client who had a bowel resection the previous day and notes that 1000 ml of gastric secretions were collected in the last 4 hours. What condition is the client at risk for developing?

• A. Metabolic alkalosis
• B. Hyperkalemia
• C. Metabolic acidosis
• D. Hypoglycemia

Correct answer: A

Rationale: The correct answer is A: Metabolic alkalosis. Loss of gastric secretions, which contain stomach acid, can lead to metabolic alkalosis. Excessive loss of acid results in an increase in the blood pH, leading to alkalosis. Hyperkalemia (B) is an elevated potassium level and is not directly related to the loss of gastric secretions. Metabolic acidosis (C) is an acid-base imbalance characterized by low pH and bicarbonate levels, which is the opposite of what would occur with the loss of gastric secretions. Hypoglycemia (D) is low blood sugar and is not typically associated with the scenario described in the question.

4. A healthcare professional reviews the blood gas results of a client in respiratory distress. The pH is 7.32, and the PCO2 is 50 mm Hg. Which of the following acid-base imbalances does the professional recognize in these findings?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: C

Rationale: In respiratory acidosis, the pH is low (<7.35) and the PCO2 is increased (>45 mm Hg). These findings indicate that the client is experiencing respiratory acidosis, a condition where there is an excess of carbon dioxide in the blood due to inadequate ventilation, commonly seen in respiratory distress. Metabolic acidosis (Choice A) is characterized by a low pH and decreased bicarbonate levels, which is not the case in this scenario. Metabolic alkalosis (Choice B) is associated with a high pH and increased bicarbonate levels. Respiratory alkalosis (Choice D) is marked by a high pH and decreased PCO2, opposite to the values presented in the blood gas results of this client.

5. After teaching a client with bacterial cystitis who is prescribed phenazopyridine (Pyridium), the nurse assesses the client’s understanding. Which statement made by the client indicates a correct understanding of the teaching?

• A. I will not take this drug with food or milk.
• B. If I suspect pregnancy, I will discontinue the drug.
• C. An orange color in my urine should not alarm me.
• D. I will consume two glasses of cranberry juice daily.

Correct answer: C

Rationale: The correct answer is C. Phenazopyridine commonly discolors urine to a deep reddish orange, which can be mistaken for blood. It is important for the client to understand that this color change is an expected side effect and should not be a cause for alarm. Additionally, the urine can stain clothing. There are no dietary restrictions or precautions related to food or milk intake while taking phenazopyridine. Stopping the medication if suspecting pregnancy is not necessary as phenazopyridine is safe to use during pregnancy. Drinking cranberry juice is not directly related to the use of phenazopyridine and is not a specific instruction given for managing bacterial cystitis.
