1. What is the expected ECG finding in a patient with hypokalemia?

• A. Flattened T waves
• B. Elevated ST segments
• C. Widened QRS complexes
• D. Widened QRS complexes on the ECG

Correct answer: A

Rationale: The correct answer is A: Flattened T waves. In hypokalemia, there is a decrease in serum potassium levels, which can lead to various ECG changes. One of the classic ECG findings associated with hypokalemia is the presence of flattened T waves. These T wave abnormalities are typically seen in multiple leads. Choice B, elevated ST segments, is not a typical ECG finding in hypokalemia. Choice C, widened QRS complexes, is more commonly associated with hyperkalemia rather than hypokalemia. Choice D is redundant and not a standard way of describing ECG findings.

2. A client is being taught about fecal occult blood testing (FOBT) for colorectal cancer screening. Which of the following statements should the nurse include in the teaching?

• A. Your provider will use a stool sample obtained during a digital rectal examination to perform the test.
• B. Your provider will recommend a stimulant laxative before the test to empty the bowel.
• C. You should start annual fecal occult blood testing for colorectal cancer screening at the age of 40.
• D. You should avoid corticosteroids before the test.

Correct answer: D

Rationale: The correct answer is D because the nurse should advise the client to avoid corticosteroids, anti-inflammatory medications, and vitamin C before fecal occult blood testing to prevent false-positive results. Choice A is incorrect as stool samples for FOBT are usually collected using a kit at home. Choice B is incorrect because stimulant laxatives are not typically used before FOBT. Choice C is incorrect as guidelines recommend starting colorectal cancer screening at the age of 50, not 40.

3. What are the early signs of increased intracranial pressure (IICP)?

• A. Restlessness, irritability, and confusion
• B. Sudden onset of seizures
• C. Decreased heart rate and pupillary response
• D. Loss of consciousness

Correct answer: A

Rationale: The correct answer is A: Restlessness, irritability, and confusion are early signs of increased intracranial pressure (IICP). These signs indicate that the brain is starting to experience pressure, often due to conditions such as trauma, tumors, or hemorrhage. Sudden onset of seizures (choice B) is not typically an early sign of IICP but can occur later as the pressure increases. Decreased heart rate and pupillary response (choice C) are more indicative of late-stage IICP as the brainstem becomes compromised. Loss of consciousness (choice D) is a late sign of IICP when the pressure has significantly increased and is causing significant brain dysfunction.

4. What are the expected ECG changes in hypokalemia?

• A. Flattened T waves
• B. ST elevation
• C. Wide QRS complex
• D. Tall T waves

Correct answer: A

Rationale: Flattened T waves are the most common ECG change seen in patients with hypokalemia. Hypokalemia leads to a decrease in serum potassium levels, affecting the repolarization phase of the cardiac action potential. This results in T wave flattening or inversion. ST elevation is typically seen in conditions like myocardial infarction, not in hypokalemia. Wide QRS complex is more associated with hyperkalemia than hypokalemia. Tall T waves are often seen in hyperkalemia, not hypokalemia.

5. What action should a healthcare provider take if a patient reports cramping during enema administration?

• A. Lower the height of the solution container
• B. Increase the flow of the enema solution
• C. Stop the procedure and remove the tubing
• D. Continue the enema at a slower rate

Correct answer: A

Rationale: When a patient reports cramping during enema administration, the best action is to lower the height of the enema solution container. This adjustment helps relieve abdominal cramping by slowing down the flow of the enema, making it more comfortable for the patient. Increasing the flow of the solution (choice B) would exacerbate the cramping. Stopping the procedure and removing the tubing (choice C) may be necessary in some cases but should not be the first response to cramping. Continuing the enema at a slower rate (choice D) might not be as effective as lowering the height of the solution container in addressing the cramping.
