Nursing Leadership and Management
1. Which of the following is the best guarantee that the patient’s priority needs are met?
- A. Checking with the relative of the patient
- B. Preparing a nursing care plan in collaboration with the patient
- C. Consulting with the physician
- D. Coordinating with other members of the team
Correct answer: B
Rationale: Preparing a nursing care plan in collaboration with the patient is the best guarantee that the patient's priority needs are met because it involves actively involving the patient in their own care. This approach ensures that the patient's preferences, concerns, and priorities are taken into account when planning their care. Checking with the relative of the patient, consulting with the physician, and coordinating with other team members are important aspects of patient care, but collaborating with the patient directly ensures a patient-centered approach that addresses their individual needs and preferences.
2. Lymph nodes are small, bean-shaped structures found along lymphatic vessels. What is their primary function?
- A. To store excess lymph fluid
- B. To produce red blood cells
- C. To filter lymph and fight infection
- D. To transport lymph to the heart
Correct answer: C
Rationale: The correct answer is C. Lymph nodes are crucial components of the immune system. Their primary function is to filter lymph, which is a clear fluid containing white blood cells, and to fight off infections. Lymph nodes contain specialized cells that help trap and destroy pathogens, such as bacteria and viruses, that may be present in the lymph fluid. This process helps to prevent the spread of infections throughout the body and plays a key role in maintaining overall immune function. Therefore, option C, 'To filter lymph and fight infection,' is the most appropriate description of the primary function of lymph nodes.
3. Which of the following is NOT a factor affecting the rate of a chemical reaction?
- A. Concentration of reactants
- B. Temperature
- C. Presence of a catalyst
- D. Color of the reaction mixture
Correct answer: D
Rationale: Color of the reaction mixture. While color change can sometimes be an indicator of a reaction, it doesn't directly influence the reaction rate.
4. What is the primary difference between ionic and metallic bonding?
- A. Ionic bonds involve electron sharing, while metallic bonds involve electron transfer.
- B. Ionic bonds are weak and directional, while metallic bonds are strong and non-directional.
- C. Ionic bonds exist between metals and non-metals, while metallic bonds exist only between metals.
- D. Ionic bonds form discrete molecules, while metallic bonds form extended structures.
Correct answer: B
Rationale: Ionic bonds form discrete molecules, while metallic bonds form extended structures. Ionic bonds involve complete electron transfer between specific atoms, resulting in discrete molecules. Metallic bonds involve a "sea" of delocalized electrons shared across all metal atoms, leading to strong, non-directional bonding throughout the entire material.
5. What is the primary function of ribosomes in the cell?
- A. To synthesize lipids and other cellular components
- B. To package and transport proteins
- C. To break down macromolecules
- D. To translate mRNA into proteins
Correct answer: D
Rationale: Rationale: Ribosomes are cellular organelles responsible for protein synthesis. They read the genetic information encoded in messenger RNA (mRNA) and use this information to assemble amino acids into a specific sequence, forming a protein. This process is known as translation and is essential for the production of proteins that carry out various functions in the cell. Options A, B, and C do not accurately describe the primary function of ribosomes in the cell.
6. What is the primary hormone released by the parathyroid glands?
- A. Insulin
- B. Calcitonin
- C. Parathyroid hormone (PTH)
- D. Thyroxine
Correct answer: C
Rationale: The primary hormone released by the parathyroid glands is Parathyroid hormone (PTH), which plays a crucial role in regulating calcium levels in the body. Insulin is produced by the pancreas to regulate blood sugar levels and is unrelated to the parathyroid glands. Calcitonin is produced by the thyroid gland and helps regulate calcium levels but is not the primary hormone released by the parathyroid glands. Thyroxine is a hormone produced by the thyroid gland that regulates metabolism and is also not released by the parathyroid glands. Therefore, the correct answer is C: Parathyroid hormone (PTH).
