What is the priority action if a patient experiences abdominal cramping during enema administration?

Correct Answer: A

Rationale: During enema administration, if a patient experiences abdominal cramping, the priority action is to lower the height of the solution container. This adjustment can help relieve abdominal cramping by reducing the flow rate of the enema, making it more comfortable for the patient. Increasing the flow of the enema solution (Choice B) can exacerbate the cramping. Stopping the procedure and removing the tubing (Choice C) may be necessary in some cases of severe discomfort or complications, but adjusting the height of the solution container should be the initial response. Continuing the enema at a slower rate (Choice D) may not address the immediate need to alleviate the cramping.

Correct Answer: A

Rationale: The correct answer is A: Flattened T waves on the ECG. Flattened T waves are an early indicator of hypokalemia on an ECG. Choice B, Elevated ST segments, is not typically seen in hypokalemia but can be a sign of myocardial infarction. Choice C, Widened QRS complex, is more commonly associated with hyperkalemia. Choice D, Prominent U waves, is typically associated with hypokalemia, but flattened T waves are considered a more specific and early sign.

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.

Correct Answer: A

Rationale: Administering sublingual nitroglycerin is the priority initial action for a patient with chest pain and acute coronary syndrome. Nitroglycerin helps vasodilate coronary arteries, improving blood flow to the heart muscle and reducing chest pain. Checking the patient's urine output (choice B) and cardiac enzymes (choice C) are important assessments but are not the first priority when managing acute chest pain. Obtaining IV access (choice D) is essential for administering medications and fluids, but administering sublingual nitroglycerin takes precedence in the initial management of chest pain in acute coronary syndrome.

Correct Answer: A

Rationale: When a patient experiences abdominal cramping during enema administration, the appropriate action is to lower the height of the enema solution container. This adjustment helps alleviate the cramping by reducing the pressure of the solution entering the colon. Stopping the procedure and removing the tubing (Choice B) is not necessary unless there are other complications. Continuing the enema at a slower rate (Choice C) may not address the immediate discomfort caused by cramping. Increasing the flow of the enema solution (Choice D) can exacerbate the cramping and should be avoided.
