1. Which electrolyte imbalance is most concerning in a patient taking digoxin?

A. Monitor potassium levels
B. Monitor calcium levels
C. Monitor sodium levels
D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels. Patients taking digoxin are at risk of developing toxicity due to hypokalemia. Low potassium levels can potentiate the toxic effects of digoxin on the heart, leading to serious arrhythmias. Monitoring calcium levels (Choice B) is not the primary concern in patients taking digoxin. While calcium levels play a role in cardiac function, hypocalcemia is not directly associated with digoxin toxicity. Monitoring sodium levels (Choice C) is important for other conditions but is not the primary concern in a patient taking digoxin. Monitoring magnesium levels (Choice D) is also essential, but hypomagnesemia is not as directly linked to digoxin toxicity as hypokalemia.

2. When digitally evacuating stool from a client with a fecal impaction, what action should the nurse take?

A. Insert a lubricated gloved finger and advance along the rectal wall
B. Apply lubricant and stimulate peristalsis
C. Apply pressure to the abdomen to assist with the removal
D. Increase fluid intake before the procedure

Correct answer: A

Rationale: The correct action when digitally evacuating stool from a client with a fecal impaction is to insert a lubricated gloved finger and advance along the rectal wall. This technique helps prevent trauma and is the appropriate method for addressing fecal impaction. Choice B is incorrect as stimulating peristalsis will not directly assist in evacuating the impacted stool. Choice C is incorrect as applying pressure to the abdomen is not the recommended method for stool evacuation. Choice D is incorrect as increasing fluid intake does not directly aid in digitally evacuating the stool.

3. A nurse in an emergency department is assessing a newly admitted client who is experiencing drooling and hoarseness following a burn injury. Which of the following actions should the nurse take first?

A. Obtain a baseline ECG
B. Obtain a blood specimen for ABG analysis
C. Insert an 18-gauge IV catheter
D. Administer 100% humidified oxygen

Correct answer: D

Rationale: In a client experiencing drooling and hoarseness following a burn injury, the priority action for the nurse is to administer 100% humidified oxygen. This is crucial to maintain the airway and address respiratory distress, which takes precedence over obtaining an ECG, collecting blood for ABG analysis, or inserting an IV catheter. Providing oxygen therapy is essential in ensuring the client's oxygenation and respiratory function are optimized in this emergency situation.

4. What is the most important nursing action for a patient post-surgery?

A. Monitor vital signs
B. Monitor the surgical site
C. Check blood pressure
D. Check oxygen saturation

Correct answer: A

Rationale: The most crucial nursing action for a patient post-surgery is to monitor vital signs. Monitoring vital signs helps in detecting early signs of complications such as hemorrhage, shock, or infection. While monitoring the surgical site is important for assessing wound healing and signs of infection, it is secondary to monitoring vital signs. Checking blood pressure and oxygen saturation are also important, but they are components of monitoring vital signs.

5. A nurse is assessing a client who has a urinary tract infection and is receiving ciprofloxacin. Which of the following findings should the nurse report to the provider?

A. Dry mouth.
B. Photosensitivity.
C. Headache.
D. Urinary retention.

Correct answer: B

Rationale: The correct answer is B: Photosensitivity. Ciprofloxacin can cause photosensitivity, making the client more sensitive to sunlight. It is essential for the nurse to report this finding to the provider so that appropriate measures can be taken to prevent skin damage. Dry mouth, headache, and urinary retention are not typically associated with ciprofloxacin use and do not require immediate reporting to the provider in this scenario.
