Nursing Elites

1. If 3 nurses can care for 15 patients, how many nurses are needed for 25 patients?

• A. 4
• B. 5
• C. 6
• D. 7

Correct answer: B

Rationale: 3 nurses / 15 patients = x nurses / 25 patients. Solve for x.

2. What is the process by which a fertilized egg implants itself in the lining of the uterus?

• A. Fertilization
• B. Implantation
• C. Gestation
• D. Parturition

Correct answer: B

Rationale: The correct answer is B: Implantation. Implantation is the process by which a fertilized egg, or zygote, attaches itself to the uterine wall to establish a pregnancy. Fertilization is the fusion of sperm and egg to form a zygote, which occurs in the fallopian tube. Gestation refers to the period of development of the fetus inside the uterus. Parturition is the process of giving birth. Therefore, implantation specifically refers to the attachment of the fertilized egg to the uterine lining, making it the most appropriate answer in this context.

3. Which word correctly completes the sentence: "He was _____ by the kindness of strangers."

• A. affected
• B. infected
• C. effected
• D. defected

Correct answer: C

Rationale: "Effected" means to produce a result or impression, aligning with the emotional impact of the strangers' kindness.

4. What is the name of the microscopic filtering unit within the kidney responsible for waste removal and blood volume regulation?

• A. Nephron
• B. Ureteric bud
• C. Renal pyramid
• D. Glomerulus

Correct answer: A

Rationale: The correct answer is A: Nephron. The nephron is the functional unit of the kidney responsible for waste removal and blood volume regulation. It consists of the renal corpuscle, including the glomerulus for filtration, and the renal tubule for reabsorption and secretion. The other options, such as the ureteric bud, renal pyramid, and glomerulus, are structures within the kidney but do not specifically refer to the filtering unit responsible for waste removal and blood volume regulation like the nephron does.

5. Which of the following is the main organ responsible for producing antibodies?

• A. Thymus gland
• B. Spleen
• C. Bone marrow
• D. Lymph nodes

Correct answer: C

Rationale: Rationale: Antibodies are proteins produced by specialized white blood cells called B lymphocytes (B cells). These B cells mature in the bone marrow, where they undergo a process of differentiation and maturation to become plasma cells that secrete antibodies. The bone marrow is the primary site for the production of B cells and antibodies in the immune system. The thymus gland is responsible for the maturation of T lymphocytes (T cells), not antibody production. The spleen and lymph nodes play roles in filtering and trapping pathogens but are not the main organs responsible for producing antibodies.

6. Which organelle is responsible for controlling the activities of the cell?

• A. Golgi apparatus
• B. Mitochondria
• C. Nucleus
• D. Ribosomes

Correct answer: C

Rationale: Rationale: The nucleus is the organelle responsible for controlling the activities of the cell. It contains the cell's genetic material (DNA) and serves as the command center of the cell, regulating gene expression and directing cellular activities. The nucleus plays a crucial role in cell growth, metabolism, and reproduction. The Golgi apparatus is involved in processing and packaging proteins, the mitochondria are responsible for producing energy in the form of ATP, and ribosomes are involved in protein synthesis. However, none of these organelles have the primary function of controlling the activities of the cell like the nucleus does.
