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

• A. Tall T waves and Pathologic Q wave
• B. Widening QRS Complex and U wave
• C. None of the above
• D. Both A and B

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.

2. What side effect is commonly associated with ECT?

• A. Transient loss of memory, confusion, and disorientation
• B. Nausea and vomiting
• C. Fractures
• D. Hypertension and increased heart rate

Correct answer: A

Rationale: The correct answer is A, as Electroconvulsive Therapy (ECT) is commonly associated with side effects such as transient loss of memory, confusion, and disorientation. While nausea and vomiting (Choice B) can occur, they are not as common as the memory-related side effects. Fractures (Choice C) are unlikely unless a mishap occurs during the procedure. Hypertension and increased heart rate (Choice D) might occur during the procedure due to the physiological stress of the treatment, but these are not the most commonly associated side effects. The rationale provided did not effectively explain this, so it's important to note that ECT is a procedure often used for severe depression and other mental illnesses, and understanding its side effects is crucial for patient safety and effective care.

3. In a patient with chronic kidney disease, which dietary modification is recommended?

• A. Increase protein intake
• B. Reduce potassium intake
• C. Increase sodium intake
• D. Reduce fiber intake

Correct answer: B

Rationale: Reducing potassium intake is important for patients with chronic kidney disease to prevent hyperkalemia.

4. Compared to the typical American diet, what does the DASH diet provide more of?

• A. More saturated fats
• B. Fewer whole grains
• C. More fruits and vegetables
• D. Fewer dairy products

Correct answer: C

Rationale: The correct answer is C. The DASH diet, which stands for Dietary Approaches to Stop Hypertension, emphasizes the consumption of fruits and vegetables, which are high in potassium, fiber, and antioxidants. These nutrients help lower blood pressure. Therefore, compared to the typical American diet, the DASH diet provides more fruits and vegetables. Choices A, B, and D are incorrect. The DASH diet doesn't focus on providing more saturated fats or fewer whole grains or dairy products. In fact, it encourages the consumption of whole grains and low-fat dairy products to promote a balanced and healthy diet.

5. Which of the following is not true about Pure Experimental research?

• A. There is a control group
• B. There is an experimental group
• C. Selection of subjects in the control group is randomized
• D. There is a careful selection of subjects in the experimental group

Correct answer: D

Rationale: In Pure Experimental research, subjects in the experimental group are typically selected randomly to minimize bias and ensure that the results are attributable to the intervention being studied. Therefore, the statement 'There is a careful selection of subjects in the experimental group' is not true. This careful selection would introduce bias and compromise the validity of the experimental results. Choices A, B, and C are true for Pure Experimental research as it involves both a control group, an experimental group, and randomization of subject selection in the control group to ensure comparability.
