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. 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.

3. A patient is receiving discharge instructions for GERD. Which of the following statements by the patient demonstrates an understanding of the teaching?

A. I should take my medication with orange juice.
B. Having a bedtime snack will prevent heartburn.
C. I will lie down after meals.
D. I will limit activities that require bending at the waist.

Correct answer: D

Rationale: The correct answer is D. Patients with GERD should avoid activities that increase intra-abdominal pressure, such as bending at the waist, as this can lead to reflux. Choice A is incorrect because medications for GERD are usually taken with water, not citrus juices. Choice B is incorrect as having a bedtime snack can worsen GERD symptoms. Choice C is incorrect because lying down after meals can also exacerbate reflux due to the effects of gravity.

4. What is the initial action for treating chest pain in acute coronary syndrome?

A. Administer sublingual nitroglycerin
B. Administer aspirin
C. Check cardiac enzymes
D. Obtain IV access

Correct answer: A

Rationale: The correct initial action for treating chest pain in acute coronary syndrome is to administer sublingual nitroglycerin. Nitroglycerin helps dilate blood vessels, reducing the workload on the heart and improving blood flow to the heart muscle. Administering aspirin can also be beneficial, but the priority is to address chest pain promptly. Checking cardiac enzymes and obtaining IV access are important steps but are not the initial actions needed to alleviate chest pain in acute coronary syndrome.

5. How does hyponatremia place the patient at risk?

A. Seizures
B. Fatigue
C. Cardiac dysrhythmias
D. Muscle weakness

Correct answer: C

Rationale: Hyponatremia places the patient at risk for cardiac dysrhythmias. While hyponatremia can lead to seizures due to cerebral edema caused by fluid imbalance, the most immediate and life-threatening risk is cardiac dysrhythmias. Low sodium levels can disrupt the heart's electrical activity, potentially leading to fatal arrhythmias. Although fatigue and muscle weakness are symptoms of hyponatremia, cardiac dysrhythmias pose the most critical concern as they can have severe consequences.
