Correct Answer: D

Rationale: The 'Medicine and Treatment Record' is the document that maintains a comprehensive log of all medications and treatments provided on a routine basis. It does not refer to the 'Discharge Summary', which is a clinical report prepared by healthcare professionals at the end of a hospital stay or series of treatments. The 'Nursing Health History and Assessment Worksheet' is used to gather comprehensive data about the patient's health history and current health status, but it does not record ongoing treatment details. The 'Nursing Kardex' is a patient care information system used to quickly communicate patient needs, but it does not consistently record all medications and treatments provided.

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.

Correct Answer: D

Rationale: The correct answer is 'Termination'. This phase of the therapeutic relationship is when the nurse informs the patient about the conclusion of therapy. It is during this phase that the nurse and the patient review the goals and progress made and also discuss the upcoming termination. The other phases are not the appropriate times for discussing termination. 'Pre-orientation' is the phase before the nurse-patient relationship is established; 'Orientation' is when the nurse and patient get to know each other and set goals; and 'Working' is when these goals are pursued. Therefore, choices A, B, and C are incorrect.

Correct Answer: A

Rationale: Banana slices are the most suitable food option for toddlers to prevent choking. Toddlers are at a higher risk of choking due to their small airways and developing chewing abilities. Banana slices are soft, easy to chew, and less likely to cause choking compared to other options. Popcorn and hot dogs are common choking hazards for young children due to their shape and texture. While carrot sticks may be a healthy choice, they can also pose a choking risk due to their hardness and shape. Therefore, recommending banana slices to parents of toddlers is the safest choice to prevent choking incidents, making choice 'A' the correct answer. Choices 'B', 'C', and 'D' are incorrect because they can potentially cause choking in toddlers.

Correct Answer: C

Rationale: The correct answer is C. While it is true that Mrs. Guevarra is delegating tasks to the nurse-aide, she does not necessarily have to directly supervise or evaluate the aide. She still retains the overall accountability for the care of the client, but direct supervision of the aide is not a requirement for delegation. Choice A is incorrect because the primary purpose of delegation is not instruction. Choice B is also incorrect because although Mrs. Guevarra is delegating tasks, she still retains accountability for those tasks. Finally, choice D is incorrect because the ability to perform the task being delegated is not a requirement for the delegator; the delegatee should have the necessary skills and knowledge to perform the delegated tasks.
