1. What is the purpose of a chest tube after a lobectomy procedure, as understood by the nurse?

• A. Prevent mediastinal shift
• B. Promote chest expansion of the remaining lung
• C. Drain fluids and blood accumulated post-operatively
• D. Remove the air in the lungs to promote lung expansion

Correct answer: C

Rationale: After a lobectomy, a chest tube is typically inserted to drain fluids and blood that may have accumulated post-operatively. This tube helps to prevent complications, such as infections or pneumonia, and aids in patient recovery. While a chest tube may aid in preventing a mediastinal shift (Choice A), promoting chest expansion of the remaining lung (Choice B), and removing air in the lungs to promote lung expansion (Choice D), these are not the primary reasons for its use after a lobectomy. Therefore, Choices A, B, and D are incorrect.

2. What is the primary function of a written nursing care plan?

• A. Evaluates whether nursing care goals have been achieved
• B. Ensures the provision of quality nursing care
• C. Assists in selecting the appropriate nursing interventions
• D. Facilitates the creation of a nursing diagnosis

Correct answer: D

Rationale: A written nursing care plan fundamentally serves to facilitate the development of a nursing diagnosis. This procedure involves analyzing patient data and identifying health problems that nurses can address independently. This analysis then aids in determining the most appropriate nursing interventions for the identified health issues. Although evaluating the achievement of nursing care goals is an important aspect, it is not the primary function of a nursing care plan. Similarly, while delivering quality nursing care is crucial, it is a broader concept that includes many other facets beyond just the initial nursing diagnosis and interventions.

3. An estimated _____ percent of persons in the United States who have HIV infection are unaware that they are infected.

• A. 4%
• B. 21%
• C. 34%
• D. 49%

Correct answer: B

Rationale: The correct answer is B: '21%'. Approximately 21% of persons in the United States who have HIV infection are unaware that they are infected. This percentage represents a significant portion of individuals who are not aware of their HIV status, highlighting the importance of increased testing and awareness campaigns. Choices A, C, and D are incorrect as they do not align with the estimated percentage provided in the context.

4. A client with hypertension is being educated by a nurse about a heart-healthy diet. Which of the following statements indicates that the client understands the teaching?

• A. I will get 15% of my total daily calories from saturated fats.
• B. I will decrease the potassium in my diet.
• C. I will limit my daily sodium intake to 3 grams.
• D. I will eat five 8-ounce servings of fruit daily.

Correct answer: C

Rationale: The correct answer is C. Limiting daily sodium intake to 3 grams is crucial in managing blood pressure and is a fundamental aspect of a heart-healthy diet. High sodium intake can contribute to hypertension and cardiovascular issues. Choices A, B, and D are incorrect because getting 15% of daily calories from saturated fats, decreasing potassium intake, and eating five servings of fruit do not directly address the management of hypertension through sodium restriction.

5. Which of the following has the greatest effect on an increase in body weight?

• A. Carbohydrate intake
• B. Protein intake
• C. Fat intake
• D. Total kilocalories

Correct answer: D

Rationale: Total kilocalories have the greatest effect on body weight as they represent the overall energy intake from all macronutrients combined. While the consumption of specific macronutrients like carbohydrates, proteins, and fats can affect weight management, the total calories consumed play the most significant role in determining body weight. Therefore, choices A, B, and C are incorrect as they focus on individual macronutrients rather than the overall energy balance provided by total kilocalories.
