1. What do crackles heard on lung auscultation indicate?

• A. Cyanosis.
• B. Bronchospasm.
• C. Airway narrowing.
• D. Fluid-filled alveoli.

Correct answer: D

Rationale: Crackles heard on lung auscultation are caused by the popping open of small airways that are filled with fluid. This is commonly associated with conditions such as pulmonary edema, pneumonia, or heart failure. Cyanosis (Choice A) is a bluish discoloration of the skin and mucous membranes due to low oxygen levels in the blood, not directly related to crackles. Bronchospasm (Choice B) refers to the constriction of the airway smooth muscle, causing difficulty in breathing but does not typically produce crackles. Airway narrowing (Choice C) can lead to wheezing but is not directly linked to crackles heard on auscultation.

2. The client who experiences angina has been advised to follow a low-cholesterol diet. Which of the following meals would be best?

• A. Hamburger, salad, and milkshake.
• B. Baked liver, green beans, and coffee.
• C. Spaghetti with tomato sauce, salad, and coffee.
• D. Fried chicken, green beans, and skim milk.

Correct answer: C

Rationale: The best meal option for a client with angina following a low-cholesterol diet is spaghetti with tomato sauce, salad, and coffee. This meal is lower in cholesterol content compared to the other options provided. Hamburger with salad and milkshake, baked liver with green beans and coffee, and fried chicken with green beans and skim milk are higher in cholesterol and may not be suitable for an individual with angina who needs to adhere to a low-cholesterol diet.

3. A client has a urine specific gravity of 1.040. What action should the nurse take?

• A. Obtain a urine culture and sensitivity.
• B. Place the client on restricted fluids.
• C. Assess the client’s creatinine level.
• D. Increase the client’s fluid intake.

Correct answer: D

Rationale: A urine specific gravity of 1.040 is higher than the normal range (1.005 to 1.030) and can indicate dehydration, decreased kidney blood flow, or the presence of antidiuretic hormone. In this situation, the priority action should be to increase the client's fluid intake to address the high specific gravity. Obtaining a urine culture, placing the client on restricted fluids, or assessing the creatinine level would not directly address the underlying issue of high urine specific gravity caused by dehydration or other factors.

4. Which of the following interventions is most appropriate for a patient with left-sided heart failure?

• A. Administering IV fluids.
• B. Administering oxygen.
• C. Administering diuretics.
• D. Administering antihypertensives.

Correct answer: B

Rationale: Administering oxygen is the most appropriate intervention for a patient with left-sided heart failure because it helps improve oxygenation. In left-sided heart failure, the heart struggles to pump oxygen-rich blood to the body, leading to inadequate oxygen supply to tissues. Administering oxygen can help alleviate symptoms of hypoxia and reduce the workload on the heart. IV fluids (Choice A) may exacerbate heart failure by increasing fluid volume, diuretics (Choice C) are used to reduce fluid overload in heart failure, and antihypertensives (Choice D) are more suitable for managing hypertension, which may be a comorbidity in heart failure but are not the primary intervention for left-sided heart failure.

5. 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.
