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. What physiologic role does calcium play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance.

Correct answer: A

Rationale: The correct answer is A: 'Blood clotting, transmission of nerve impulses, muscle contraction and relaxation.' Calcium plays a crucial role in various physiological functions such as blood clotting, transmission of nerve impulses, muscle contraction and relaxation, membrane permeability, and activation of certain enzymes. Choice B is incorrect because while calcium is involved in calcium homeostasis, it is not the only role it plays in the body. Choice C is incorrect as calcium indeed has several known metabolic functions, and it is not solely for preventing caries. Choice D is also incorrect as the functions mentioned are primarily carried out by other nutrients and not specifically by calcium.

3. Which vitamin's recommended dietary allowance (RDA) is significantly increased during pregnancy?

• A. Folate
• B. Thiamine (B1)
• C. Riboflavin (B2)
• D. Niacin (B3)

Correct answer: A

Rationale: The correct answer is A: Folate. During pregnancy, the recommended dietary allowance (RDA) for folate is significantly increased to support fetal development and prevent neural tube defects and other congenital anomalies. Folate plays a crucial role in DNA synthesis and cell growth, making it essential for the rapidly dividing cells of the developing fetus. Thiamine (B1), Riboflavin (B2), and Niacin (B3) are important vitamins, but their RDAs do not undergo as significant an increase during pregnancy as folate's RDA does.

4. To ensure client safety before starting blood transfusions, the following are needed before the procedure can be done EXCEPT:

• A. take baseline vital signs
• B. warm the blood to room temperature for 30 minutes before administering the transfusion
• C. have two nurses verify client identification, blood type, unit number, and expiration date of blood
• D. get consent signed for blood transfusion

Correct answer: D

Rationale: To ensure client safety before starting blood transfusions, taking baseline vital signs, warming the blood to room temperature, and having two nurses verify client identification, blood type, unit number, and expiration date of blood are crucial steps. Consent for blood transfusion is required but is typically obtained before the procedure. The focus before the procedure should be on confirming the right client, blood product, and ensuring the blood is prepared correctly to minimize risks of transfusion reactions.

5. The most significant factor that might affect the nurse’s care for the psychiatric patient is:

• A. Nurse’s own beliefs and attitude about the mentally ill
• B. Amount of experience he has with psychiatric clients
• C. Her abilities and skill to care for the psychiatric clients
• D. Her knowledge in dealing with the psychiatric clients

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
