Nursing Elites

1. A patient has been diagnosed with diabetes mellitus. Which of the following is not a clinical sign of diabetes mellitus?

• A. Polyphagia
• B. Polyuria
• C. Metabolic acidosis
• D. Lower extremity edema

Correct answer: D

Rationale: Polyphagia, polyuria, and metabolic acidosis are common clinical signs of diabetes mellitus. Polyphagia refers to excessive hunger, polyuria is excessive urination, and metabolic acidosis can occur due to poorly controlled diabetes. Lower extremity edema, on the other hand, is not a typical clinical sign of diabetes mellitus. Edema in the lower extremities is more commonly associated with conditions like heart failure or kidney disease rather than diabetes mellitus.

2. A client comes to the clinic for assessment of his physical status and guidelines for starting a weight-reduction diet. The client's weight is 216 pounds and his height is 66 inches. The nurse identifies the BMI (body mass index) as:

• A. Within normal limits, so a weight-reduction diet is unnecessary.
• B. Lower than normal, so education about nutrient-dense foods is needed.
• C. Indicating obesity because the BMI is 35.
• D. Indicating overweight status because the BMI is 27.

Correct answer: C

Rationale: Obesity is defined by a BMI of 30 or more with no co-morbid conditions. Body Mass Index (BMI) is calculated by utilizing a chart or nomogram that plots height and weight. In this case, the client's BMI is calculated as 35, indicating obesity. A BMI of 27 falls within the overweight range, not obesity (which starts at 30). Choices A and B are incorrect because a BMI of 35 indicates obesity, not normal limits or being lower than normal. Therefore, the correct answer is C, indicating obesity based on the BMI calculation.

3. The nurse is checking laboratory values on a patient who has crackling rales in the lower lobes, 2+ pitting edema, and dyspnea with minimal exertion. Which of the following laboratory values does the nurse expect to be abnormal?

• A. Potassium.
• B. B-type natriuretic peptide (BNP).
• C. C-reactive protein (CRP).
• D. Platelets.

Correct answer: B

Rationale: The client's symptoms suggest heart failure. BNP is a neurohormone released from the ventricles due to increased pressure and stretch, as seen in heart failure. A BNP level greater than 51 pg/mL is often associated with mild heart failure, with higher levels indicating more severe heart failure. Potassium levels are not typically affected by heart failure. CRP is an inflammation indicator used to predict coronary artery disease risk, not directly related to heart failure in this case. The client's symptoms do not suggest bleeding or clotting abnormalities associated with platelet count issues, making platelets an unlikely abnormal value.

4. In a client with asthma who develops respiratory acidosis, what should the nurse expect the client's serum potassium level to be?

• A. normal
• B. elevated
• C. low
• D. unrelated to the pH

Correct answer: B

Rationale: In respiratory acidosis, the serum potassium level is expected to be elevated. This occurs because potassium shifts from cells into the bloodstream as a compensatory mechanism to maintain acid-base balance. Choices A, C, and D are incorrect. A normal potassium level is not expected in respiratory acidosis. A low potassium level is more commonly associated with alkalosis, not acidosis. The potassium level is indeed related to pH changes in respiratory acidosis, leading to the expected elevation.

5. The client is taking Antabuse and should avoid eating foods that may trigger a disulfiram reaction. The nurse should instruct the client to avoid:

• A. Peanuts, dates, raisins
• B. Figs, chocolate, eggplant
• C. Pickles, salad with vinaigrette dressing, beef
• D. Milk, cottage cheese, ice cream

Correct answer: C

Rationale: The client taking Antabuse should avoid foods that contain alcohol or vinegar as they can trigger a disulfiram reaction. Pickles and vinaigrette dressing often contain vinegar, which the client should avoid. Beef is safe to consume. Choices A, B, and D do not contain alcohol or vinegar, so they are allowed for the client taking Antabuse.
