1. Which of the following is reflected in an ECG due to hypokalemia?

Correct answer: B

Rationale: Hypokalemia, a condition characterized by low levels of potassium in the blood, is reflected in an ECG by a widening QRS Complex and a U wave. This is because potassium plays a key role in the electrical activity of the heart, and its deficiency can lead to abnormalities in the heart's rhythm as represented by these specific changes on the ECG. Choice A is incorrect as tall T waves and pathologic Q waves are more commonly associated with hyperkalemia or myocardial infarction, respectively, rather than hypokalemia. Choices C and D are also incorrect as they do not accurately reflect the ECG changes caused by hypokalemia.

Rationale: When determining priorities in patient care, assessing perfusion, respiration, and locomotion are crucial. However, assessing mentation is also important but not typically included in the ABCs of emergency care. Monitoring mentation is essential for neurological assessment and detecting changes in mental status, but it is not part of the immediate priorities in life-threatening situations.

5. Which statement by a client indicates a need for further teaching about food safety?

Correct answer: C

Rationale: The correct answer is C because drinking unpasteurized milk can contain harmful bacteria, which poses a risk to food safety. Choice A is correct as it emphasizes using food before the expiration date. Choice B is also correct as washing fruits before consumption is a good food safety practice. Choice D is correct as well since washing hands after handling raw chicken is crucial to prevent cross-contamination. Therefore, choice C is the only statement that indicates a need for further teaching on food safety.
