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.

2. A breastfeeding mother complains that she missed her son's last two feedings and now her breasts have become full, hard, and uncomfortable. This condition is known as _____.

Correct answer: B

Rationale: Engorgement occurs when the breasts become overly full, leading to discomfort and sometimes difficulty with latching. It can be relieved by feeding or expressing milk. Mastitis, choice A, is characterized by breast inflammation usually caused by an infection. Letdown, choice C, refers to the release of milk from the breast. Galactorrhea, choice D, is the spontaneous flow of milk from the breast unassociated with childbirth or nursing.

3. Hypertrophic burn scars are caused by:

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. The nurse is assessing a client with a new diagnosis of Listeria food poisoning. What action should the nurse take first?

Correct answer: D

Rationale: The correct first action for the nurse to take when assessing a client with a new diagnosis of Listeria food poisoning is to inquire if the client has consumed any unpasteurized products. This is crucial because Listeria contamination is often associated with unpasteurized dairy products and undercooked meats. Educating the client on safe food practices (Choice A) is important but not the priority at this initial assessment stage. Starting a traceback to identify the source of the outbreak (Choice B) and reporting the case to the county board of health (Choice C) are necessary actions but should come after gathering information directly from the client regarding potential exposure to high-risk foods.

5. Generally, lifestyle-related diseases share common risk factors. Which of the following is NOT one of them?

Correct answer: C

Rationale: Common risk factors for lifestyle-related diseases typically include aspects of one's lifestyle that can be modified or controlled, such as physical activity, smoking habits, and nutrition. These factors can be changed to prevent or manage lifestyle-related diseases. Genetics, on the other hand, is not a modifiable risk factor, meaning it cannot be changed or controlled. Therefore, it is not considered a common risk factor for lifestyle-related diseases. Understanding the modifiable risk factors for these diseases allows for better prevention and management strategies, and helps reduce the risk of complications.
