1. Plant stanols and sterols help to lower LDL cholesterol and are often added to which food product?

A. margarine
B. milk
C. cereal
D. yogurt

Correct answer: A

Rationale: Plant stanols and sterols are commonly added to margarine to help lower LDL cholesterol levels. Margarine acts as a vehicle for these compounds, making it easier for individuals to incorporate them into their daily diet. While milk, cereal, and yogurt are healthy food options, they are not typically enriched with plant stanols and sterols for cholesterol-lowering purposes, making them less likely candidates as the correct answer.

2. Which of the following statements about Z-Track technique is false?

A. Z-Track injections prevent irritation of the subcutaneous tissues
B. The technique involves creating a Zig-Zag like pattern of medication
C. It forces the medication to be contained in the subcutaneous tissues
D. It is used when administering Parenteral Iron

Correct answer: B

Rationale: The Z-Track technique is aimed at preventing medication leakage into the surrounding tissues by sealing the medication in the muscle, not by creating a Zig-Zag pattern. Choice A is correct as Z-Track injections help prevent irritation. Choice C is correct as it accurately describes how the technique works. Choice D is also correct as the Z-Track technique is commonly used when administering Parenteral Iron to prevent staining and irritation of the surrounding tissues.

3. Legally, Patients chart are:

A. Owned by the government since it is a legal document
B. Owned by the doctor in charge and should be kept from the administrator for whatever reason
C. Owned by the hospital and should not be given to anyone who request it other than the doctor in charge

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.

4. 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.
