Nursing Elites

1. A middle-aged adult with a family history of CAD has the following: total cholesterol 198 (11 mmol/L); LDL cholesterol 120 (6.7 mmol/L); HDL cholesterol 58 (3.2 mmol/L); triglycerides 148 (8.2 mmol/L); blood sugar 102 (5.7 mmol/L); and C-reactive protein (CRP) 4.2. The health care provider prescribes a statin medication and aspirin. The client asks the nurse why these medications are needed. Which is the best response by the nurse?

• A. The labs indicate severe hyperlipidemia and the medications will lower your LDL, along with a low-fat diet.
• B. The triglycerides are elevated and will not return to normal without these medications.
• C. The CRP is elevated indicating inflammation seen in cardiovascular disease, which can be lowered by the medications prescribed.
• D. These medications will reduce the risk of type 2 diabetes.

Correct answer: C

Rationale: CRP is a marker of inflammation, which is elevated in cardiovascular disease. Statins and aspirin help lower CRP and reduce the risk of heart attacks and strokes.

2. Which of the following conditions is the most significant risk factor for the development of type 2 diabetes mellitus?

• A. Cigarette smoking.
• B. High-cholesterol diet.
• C. Obesity.
• D. Hypertension.

Correct answer: C

Rationale: Obesity is the most significant risk factor for developing type 2 diabetes mellitus due to its role in insulin resistance. Excess body fat, especially around the abdomen, leads to increased production of inflammatory markers and hormones that can cause insulin resistance. While cigarette smoking, high-cholesterol diet, and hypertension can contribute to health issues, they are not as directly linked to the development of type 2 diabetes mellitus as obesity.

3. A client without a history of respiratory disease has a pulse oximeter in place after surgery. The nurse monitors the pulse oximeter readings to ensure that oxygen saturation remains above:

• A. 85%
• B. 89%
• C. 95%
• D. 100%

Correct answer: C

Rationale: Pulse oximetry is a noninvasive method of continuously monitoring the oxygen saturation of hemoglobin (SaO2). In the absence of underlying respiratory disease, the expected oxygen saturation level is at least 95%. Oxygen saturation levels below 95% may indicate hypoxemia, which can compromise tissue perfusion and oxygen delivery to vital organs. Therefore, maintaining oxygen saturation above 95% is crucial to ensure adequate oxygenation post-surgery. Choices A, B, and D are incorrect as they represent oxygen saturation levels that are below the expected value for a client without a history of respiratory disease, which should be at least 95%.

4. A nurse reviews a female client’s laboratory results. Which result from the client’s urinalysis should the nurse recognize as abnormal?

• A. pH 5.6
• B. Ketone bodies present
• C. Specific gravity of 1.020
• D. Clear and yellow color

Correct answer: B

Rationale: The correct answer is B: Ketone bodies present. Ketone bodies in urine indicate abnormal metabolism, specifically the incomplete breakdown of fatty acids. Normally, there should be no ketones present in urine. Ketone bodies are produced when the body uses fat sources instead of glucose for cellular energy. A pH range between 4.6 and 8, a specific gravity between 1.005 and 1.030, and clear yellow color in urine are considered normal findings for a female client’s urinalysis. Therefore, options A, C, and D are within normal ranges and not indicative of abnormal results in the urinalysis.

5. The nurse assesses a client with advanced cirrhosis of the liver for signs of hepatic encephalopathy. Which finding would the nurse consider an indication of progressive hepatic encephalopathy?

• A. An increase in abdominal girth.
• B. Hypertension and a bounding pulse.
• C. Decreased bowel sounds.
• D. Difficulty in handwriting.

Correct answer: D

Rationale: Difficulty in handwriting is a common early sign of hepatic encephalopathy. Changes in handwriting can indicate progression or reversal of hepatic encephalopathy leading to coma. Choice (A) is a sign of ascites, not hepatic encephalopathy. Hypertension and a bounding pulse (Choice B) are not typically associated with hepatic encephalopathy. Decreased bowel sounds (Choice C) do not directly indicate an increase in serum ammonia level, which is the primary cause of hepatic encephalopathy.
