Nursing Elites

1. Folate is crucial for DNA synthesis and cell division, making it particularly important during periods of rapid growth, such as pregnancy.

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: The correct answer is A. Folate plays a crucial role in DNA synthesis and cell division, which are essential processes for cell multiplication. This makes folate particularly important during periods of rapid growth, such as pregnancy. Therefore, the statement is true. Choice B is incorrect because it fails to acknowledge the significance of folate in cell multiplication and rapid growth, especially during pregnancy.

2. When doing an initial assessment, the best way for you to identify the client’s priority problem is to:

• A. Interview the client for chief complaints and other symptoms
• B. Talk to the relatives to gather data about history of illness
• C. Do auscultation to check for chest congestion
• D. Do a physical examination while asking the client relevant questions

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

3. Mr. CKK is unconscious and was brought to the E.R. Who among the following can give consent for CKK's operation?

• A. Doctor
• B. Nurse
• C. Next of Kin
• D. The Patient

Correct answer: A

Rationale: In the scenario described, when a patient is unconscious and unable to provide consent, the responsibility usually falls on the physician to make decisions regarding the patient's treatment, including obtaining consent for an operation. While nurses play a crucial role in patient care, they typically do not have the authority to provide consent for a major procedure. The next of kin may be consulted for input, but the ultimate decision-making authority lies with the physician. The patient, being unconscious, is unable to provide consent in this situation.

4. Which mineral is a principal component of cell membranes?

• A. phosphorus
• B. magnesium
• C. iron
• D. iodine

Correct answer: A

Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.

5. Which bond is formed by a positively charged metal ion and negatively charged nonmetal ion?

• A. Ionic bond
• B. Covalent bond
• C. Functional group
• D. Metallic bond

Correct answer: A

Rationale: The correct answer is an ionic bond. An ionic bond is formed when a positively charged metal ion joins with a negatively charged nonmetal ion, resulting in a transfer of electrons. In contrast, a covalent bond involves sharing electrons between atoms rather than complete transfer. Functional groups are specific groups of atoms within molecules that determine the molecule's chemical properties. Metallic bonds occur between metal atoms where electrons are shared across a delocalized electron cloud.
