Correct Answer: C

Rationale: The correct answer is C because stopping medication without consulting a healthcare provider can lead to uncontrolled hypertension. Choice A shows understanding of monitoring blood pressure, B demonstrates adherence to medication regimen, and D indicates awareness of dietary management. Choice C is incorrect because abruptly stopping medication can have serious health consequences, making further education necessary.

Correct Answer: A

Rationale: The correct answer is A: "I will monitor my blood glucose regularly." This statement shows proper understanding as monitoring blood glucose levels is essential for managing diabetes effectively. Regular monitoring helps the patient track their blood sugar levels and make informed decisions about medication, diet, and lifestyle. Incorrect choices: B: Stopping insulin when blood glucose is normal can lead to dangerous complications. C: Using insulin only when symptoms of high blood sugar are present is not a safe or effective approach. D: Eating sugary foods when feeling tired or weak can cause blood sugar spikes and worsen diabetes control. In summary, choice A is correct because it reflects the importance of consistent blood glucose monitoring in diabetes management, while the other choices suggest potentially harmful misconceptions.

Correct Answer: C

Rationale: The correct answer is C. After being in critical care for 10 days, it is expected that the patient may be disoriented to time but still be oriented to place and person. This is a common occurrence due to the stressful and disorienting environment of the critical care unit. The patient's cognition may be temporarily affected, leading to difficulty in remembering the date accurately. The patient's ability to recognize their surroundings and identify themselves and others should still be intact. Choices A, B, and D are incorrect because disruption in thought content, expressing relief, and clouding of consciousness are not typical cognitive function issues expected in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Providing a source of fast-acting carbohydrate. In hypoglycemia, the priority is to quickly raise the patient's blood sugar levels to prevent potential complications like seizures or loss of consciousness. Fast-acting carbohydrates, such as glucose tablets or juice, can rapidly increase blood sugar levels. Administering insulin (A) would further lower blood sugar levels, worsening the situation. Administering an oral hypoglycemic agent (C) is not appropriate in an acute hypoglycemic episode. Monitoring blood pressure (D) is important but not the priority in this situation.

Correct Answer: A

Rationale: The correct answer is A because applying theory in real situations allows nurses to analyze, evaluate, and problem-solve effectively. This promotes critical thinking by integrating knowledge into practice. Working with physicians (B) and following orders (C) do not directly enhance critical thinking as they focus more on collaboration and task completion. Developing nursing diagnoses (D) is important but does not specifically target critical thinking skills like applying theory does.
