Which of the following is the best indicator of long-term glycemic control in a patient with diabetes?
- A. Fasting blood glucose levels.
- B. Postprandial blood glucose levels.
- C. Hemoglobin A1c.
- D. Random blood glucose levels.
Correct Answer: C
Rationale: The correct answer is C, Hemoglobin A1c. Hemoglobin A1c measures the average blood glucose level over the past 2-3 months, providing a reliable indicator of long-term glycemic control. Fasting blood glucose levels (choice A) only offer a snapshot of the current glucose level and can fluctuate throughout the day. Postprandial blood glucose levels (choice B) reflect glucose levels after meals but do not give a comprehensive view of long-term control. Random blood glucose levels (choice D) are taken at any time and lack the consistency needed to assess long-term glycemic control effectively. Therefore, Hemoglobin A1c is the superior choice for monitoring and managing diabetes over an extended period.

A client admitted with left-sided heart failure has a heart rate of 110 beats per minute and is becoming increasingly dyspneic. Which additional assessment finding by the nurse supports the client's admitting diagnosis?
- A. An enlarged, distended abdomen.
- B. Crackles in the bases of both lungs.
- C. Jugular vein distension.
- D. Peripheral edema.
Correct Answer: B
Rationale: The correct answer is B. Crackles in the bases of the lungs are indicative of fluid accumulation, which is common in left-sided heart failure. In left-sided heart failure, the heart is unable to effectively pump blood from the lungs to the rest of the body, leading to a backup of fluid in the lungs. This results in crackles heard on auscultation. Choices A, C, and D are not specific to left-sided heart failure. An enlarged, distended abdomen may indicate ascites or liver congestion. Jugular vein distension is more commonly associated with right-sided heart failure, and peripheral edema is a sign of fluid accumulation in the tissues, which can occur in both types of heart failure but is not as specific to left-sided heart failure as crackles in the lungs.
Following the diagnosis of angina pectoris, a client reports being unable to walk up two flights of stairs without pain. Which of the following measures would most likely help the client prevent this problem?
- A. Climb the stairs early in the day.
- B. Rest for at least an hour before climbing the stairs.
- C. Take a nitroglycerin tablet before climbing the stairs.
- D. Lie down after climbing the stairs.
Correct Answer: C
Rationale: The correct answer is to take a nitroglycerin tablet before climbing the stairs. Nitroglycerin helps prevent angina by dilating the coronary arteries, which increases blood flow to the heart. This medication can help reduce the chest pain and discomfort experienced during physical exertion. Climing the stairs early in the day (Choice A) does not address the underlying issue of inadequate blood flow to the heart. Resting for at least an hour before climbing the stairs (Choice B) may not be as effective in preventing angina as taking nitroglycerin. Lying down after climbing the stairs (Choice D) does not offer a preventive measure for angina; it is more focused on post-activity rest rather than prevention.
The client admitted with peripheral vascular disease (PVD) asks the nurse why her legs hurt when she walks. The nurse bases a response on the knowledge that the main characteristic of PVD is:
- A. Decreased blood flow.
- B. Increased blood flow.
- C. Slow blood flow.
- D. Thrombus formation.
Correct Answer: A
Rationale: The correct answer is A: 'Decreased blood flow.' In peripheral vascular disease (PVD), there is a narrowing or blockage of blood vessels, leading to reduced blood flow to the extremities. This decreased blood flow results in inadequate oxygen supply to the muscles, causing pain, especially during physical activity when oxygen demand increases. Choice B, 'Increased blood flow,' is incorrect because PVD is characterized by impaired blood circulation rather than increased flow. Choice C, 'Slow blood flow,' is not precise as PVD involves a more significant reduction in blood flow. Choice D, 'Thrombus formation,' is related to the formation of blood clots within vessels, which can be a complication of PVD but is not its main characteristic.
In a patient with type 1 diabetes, which of the following is a sign of diabetic ketoacidosis (DKA)?
- A. Polyuria
- B. Bradycardia
- C. Dry skin
- D. Tachycardia
Correct Answer: D
Rationale: Tachycardia is a sign of diabetic ketoacidosis (DKA) in a patient with type 1 diabetes. In DKA, the body responds to hyperglycemia and dehydration by increasing heart rate. Polyuria (increased urination) is a symptom of diabetes but not specific to DKA. Bradycardia (slow heart rate) and dry skin are not typical signs of DKA; instead, tachycardia and other signs of volume depletion are more common.
The healthcare provider is assessing a client who is receiving hemodialysis for the first time. Which of the following findings should be reported to the healthcare provider immediately?
- A. Blood pressure of 150/90 mm Hg.
- B. Nausea and vomiting.
- C. Fatigue.
- D. Headache.
Correct Answer: B
Rationale: Nausea and vomiting are critical symptoms that should be reported immediately when a client is receiving hemodialysis for the first time. These symptoms could indicate a severe complication, such as hypotension, infection, electrolyte imbalance, or other adverse reactions to the procedure. It is essential to address these symptoms promptly to prevent further complications or harm to the client. Choices A, C, and D are not immediate concerns during the first hemodialysis session and can be addressed appropriately after addressing the urgent issue of nausea and vomiting.
