1. Within a nursing program, 25% of the class wanted to work with infants, 60% wanted to work with the elderly, 10% wanted to assist general practitioners, and the rest were undecided. What fraction of the class wanted to work with the elderly?

Correct answer: C

Rationale: To find the fraction of the class wanting to work with the elderly, we convert the percentage to a fraction. 60% can be written as 60/100, which simplifies to 3/5. Therefore, 3/5 of the class wanted to work with the elderly. Choice A (1/4), choice B (1/10), and choice D (1/20) do not represent the fraction of the class wanting to work with the elderly, making them incorrect.

2. Which hormone plays a key role in stimulating the release of milk from breast tissue after childbirth?

Correct answer: C

Rationale: Prolactin is the hormone responsible for stimulating the release of milk from breast tissue after childbirth. It is produced by the pituitary gland and plays a crucial role in lactation. Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are involved in the menstrual cycle and reproductive processes, not milk production. Estrogen is a female sex hormone with various functions but is not directly involved in milk production.

3. Which of the following is a condition characterized by a loss of bone density and increased risk of fractures?

Correct answer: C

Rationale: Osteoporosis is a condition characterized by a loss of bone density, leading to fragile bones and an increased risk of fractures. Osteoarthritis is a degenerative joint disease affecting cartilage, Rickets is caused by a deficiency in vitamin D leading to impaired bone development, and Scoliosis is an abnormal sideways curvature of the spine. Therefore, the correct answer is osteoporosis as it specifically pertains to decreased bone density and fracture risk, distinguishing it from the other conditions listed.

4. How is the muscular system benefited by regular exercise?

Correct answer: B

Rationale: Regular exercise is beneficial for the muscular system by improving muscle strength and endurance. Exercise helps to build and maintain muscle mass, increase muscle strength, and enhance muscle endurance. It does not decrease muscle mass, make muscles less flexible, or increase the risk of muscle tears when done properly. Therefore, the correct answer is improving muscle strength and endurance, as it aligns with the positive effects of regular exercise on the muscular system.

5. Which muscle has involuntary cells that are branched and striated and connected by intercalated discs with gap junctions?

Correct answer: B

Rationale: The correct answer is B: Cardiac muscle. Cardiac muscle cells fit the description provided in the question; they are involuntary, striated, and branched, with intercalated discs containing gap junctions that allow for synchronized contractions of the heart. Smooth muscle (choice A) lacks striations and is found in the walls of internal organs. Skeletal muscle (choice C) is voluntary and attaches to bones for movement. 'Epithelial muscle' (choice D) is not a valid muscle type, making it an incorrect choice.
