1. What laboratory value would be considered a high-risk measure for coronary heart disease assessment?
- A. triglycerides > 150 mg/dL
- B. BMI > 31
- C. LDL cholesterol < 128 mg/dL
- D. blood pressure of 128/82 mmHg
Correct answer: B
Rationale: The correct answer is B: BMI > 31. A BMI over 31 is considered a high-risk factor for coronary heart disease as it indicates obesity, which is strongly linked to cardiovascular issues. Triglycerides > 150 mg/dL (choice A) can contribute to heart disease risk but are not as specific as BMI in assessing overall risk. LDL cholesterol < 128 mg/dL (choice C) is actually a desirable level, indicating lower risk. A blood pressure of 128/82 mmHg (choice D) is within normal range and not a high-risk measure specifically for coronary heart disease.
2. 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.
3. The nurse interprets the statement “Bow down before me! I am the holy mother of Christ! I am the blessed Virgin Mary!†as important in documenting in which of the following areas of mental status examination?
- A. Thought content
- B. Mood
- C. Affect
- D. Attitude
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.
4. The term associated with loss of taste is:
- A. Xerostomia
- B. Hypogeusia
- C. Dysphagia
- D. Anosmia
Correct answer: B
Rationale: The correct answer is B, 'Hypogeusia.' Hypogeusia refers to a diminished sense of taste, which can impact nutritional intake, especially in older adults. Xerostomia (choice A) is dry mouth, Dysphagia (choice C) is difficulty swallowing, and Anosmia (choice D) is the loss of the sense of smell. These conditions are different from loss of taste, making them incorrect choices for this question.
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.
