Correct Answer: D

Rationale: The correct answer is D: Hyperglycemia. Patients with diabetes are at risk for high blood sugar levels, leading to hyperglycemia. This can result in various complications such as diabetic ketoacidosis or hyperosmolar hyperglycemic state. The nurse should monitor the patient's blood glucose levels regularly to prevent these serious complications. Explanation for incorrect choices: A: Hypoglycemia - While hypoglycemia is a concern for diabetic patients, hyperglycemia is a more common and immediate risk. B: Hyperkalemia - While hyperkalemia can occur in some diabetic patients, hyperglycemia is a more common and primary concern. C: Hypotension - While diabetic patients can experience hypotension, hyperglycemia poses a more immediate threat to their health.

Correct Answer: A

Rationale: Correct Answer: A - Encouraging early ambulation Rationale: 1. Early ambulation helps prevent post-operative complications like blood clots and pneumonia. 2. Movement promotes circulation, aids in lung expansion, and prevents muscle atrophy. 3. It also supports bowel function and helps prevent constipation, a common post-operative issue. 4. Ambulation aids in overall recovery and reduces the risk of complications associated with prolonged immobility. Other Choices: B: Administering pain medication - Important for comfort but not the top priority for preventing complications. C: Providing wound care and dressing changes - Necessary for wound healing but not the immediate priority to prevent complications. D: Monitoring for signs of infection - Critical but not the primary intervention to prevent complications immediately post-op.

Correct Answer: C

Rationale: The correct answer is C because prevention emphasizes the importance of personal behavior in maintaining health. It highlights the role of individual choices in preventing diseases and promoting well-being. A is incorrect because prevention focuses on proactive measures rather than treating external factors. B is incorrect as it contradicts the importance of prevention in reducing preventable deaths. D is incorrect because prevention is about avoiding health issues before they occur, not treating them after they have developed.

Correct Answer: A

Rationale: The correct answer is A. Regularly checking blood glucose levels is crucial for diabetic patients to monitor their condition and adjust treatment as needed. This helps in managing blood sugar levels effectively and preventing complications. Choice B is incorrect because stopping insulin abruptly can lead to dangerous fluctuations in blood sugar levels. Choice C is incorrect because while exercise is important for diabetic patients, vigorous exercise every day may not be suitable for everyone and should be discussed with healthcare providers. Choice D is incorrect as carbohydrates are an essential source of energy and nutrients for the body. Diabetic patients can still consume carbohydrates in controlled portions as part of a balanced diet.

Correct Answer: A

Rationale: The correct answer is A: Hypertensive crisis. The nurse should be most concerned about this option because the patient has a history of hypertension and is experiencing new onset symptoms such as headaches, nausea, and dizziness, which could indicate a sudden and severe increase in blood pressure. This condition, if left untreated, can lead to serious complications such as stroke or heart attack. Summary: - B: Migraine headache is unlikely as the symptoms described are not typical of a migraine. - C: Benign positional vertigo is unlikely as it does not explain the presence of headaches and nausea. - D: Tension headache is less concerning compared to hypertensive crisis, given the patient's history of hypertension and the severity of symptoms.
