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

• A. There is a control group
• B. There is an experimental group
• C. Selection of subjects in the control group is randomized
• D. There is a careful selection of subjects in the experimental group

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. After cleaning the abrasions and applying antiseptic, the nurse applies a cold compress to the swollen ankle as ordered by the physician. This statement shows that the nurse has a correct understanding of the use of a cold compress:

• A. Cold compress reduces blood viscosity in the affected area
• B. It is safer to apply than a hot compress
• C. Cold compress prevents edema and reduces pain
• D. It eliminates toxic waste products due to vasodilation

Correct answer: C

Rationale: The correct understanding of using a cold compress includes knowing that it helps prevent edema and reduces pain. Cold application constricts blood vessels, reducing blood flow to the area, which helps decrease swelling and pain. Choices A, B, and D are incorrect because cold compresses do not directly affect blood viscosity, safety compared to hot compresses, or eliminate toxic waste products due to vasodilation. It is essential for nurses to have a clear understanding of the rationale behind interventions to provide effective patient care.

3. When rickets occurs, how is the alveolar bone affected compared to other bones in the body?

• A. Both statements are true.
• B. Both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: A

Rationale: Both statements are true. When rickets occurs, the alveolar bone is affected similar to other bones in the body, with the trabeculae of the alveolar bone also weakening. In addition to damaged alveolar bone caused by vitamin D deficiency, dental changes include delayed dentition and small molars. The other choices are incorrect because both statements provided are accurate based on the effects of rickets on the alveolar bone.

4. Which student lunch is the least nutritious?

• A. Ham sandwich, apple, and milk
• B. Hamburger, fries, and soft drink
• C. Macaroni and cheese, green beans, and peaches
• D. Meatloaf, broccoli, and pear slices

Correct answer: B

Rationale: The correct answer is B - 'Hamburger, fries, and soft drink' as it contains foods high in unhealthy fats, sugars, and low nutritional value. A hamburger, fries, and a soft drink are considered less nutritious compared to the other options. Choice A includes a ham sandwich, apple, and milk, which provide a balance of protein, fiber, and calcium. Choice C consists of macaroni and cheese, green beans, and peaches, offering a mix of carbohydrates, vegetables, and fruits. Choice D contains meatloaf, broccoli, and pear slices, which provide a good source of protein, vitamins, and fiber. Therefore, option B is the least nutritious among the given choices.

5. The principal cation in plasma and interstitial fluid is:

• A. Sodium
• B. Potassium
• C. Calcium
• D. Magnesium

Correct answer: A

Rationale: The principal cation in plasma and interstitial fluid is sodium. Sodium plays a crucial role in maintaining fluid balance and is the primary cation in extracellular fluids like plasma and interstitial fluid. Potassium is the primary cation within cells, not in extracellular fluids, making it an incorrect choice. Calcium and magnesium are essential minerals but are not the principal cations in plasma and interstitial fluid, so they are also incorrect choices.
