1. Which of the following is not true about Pure Experimental research?

Correct answer: D

Rationale: In Pure Experimental research, subjects in the experimental group are typically selected randomly to minimize bias and ensure that the results are attributable to the intervention being studied. Therefore, the statement 'There is a careful selection of subjects in the experimental group' is not true. This careful selection would introduce bias and compromise the validity of the experimental results. Choices A, B, and C are true for Pure Experimental research as it involves both a control group, an experimental group, and randomization of subject selection in the control group to ensure comparability.

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

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.

3. Following bariatric surgery, a patient would initially be given what type of diet?

Correct answer: C

Rationale: A clear liquid diet is typically the first step after bariatric surgery to allow the stomach to heal and prevent complications.

4. As a nurse assigned for care for geriatric patients, you need to frequently assess your patient using the nursing process. Which of the following needs be considered with the highest priority?

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

5. A dietitian tells you that you are not consuming enough calories. Which of the following nutrients could you add to your diet to increase your energy intake?

Correct answer: C

Rationale: Corrected Rationale: Protein provides 4 kcal per gram, making it a good source of energy to increase caloric intake. While fiber and water are important for other aspects of health, they do not provide energy like protein does. Vitamins are essential for various bodily functions but do not contribute directly to caloric intake.
