1. What disease is characterized by progressive muscle weakness and wasting?

A. Muscular dystrophy
B. Myositis
C. Fibromyalgia
D. Carpal tunnel syndrome

Correct answer: A

Rationale: The correct answer is A: Muscular dystrophy. Muscular dystrophy is a genetic disorder characterized by progressive muscle weakness and wasting over time. It primarily affects skeletal muscles, leading to difficulties in movement and muscle function. Myositis is an inflammatory condition affecting the muscles, but it may not always result in progressive muscle weakness and wasting. Fibromyalgia is a chronic pain disorder characterized by widespread musculoskeletal pain and fatigue, not necessarily progressive muscle weakness. Carpal tunnel syndrome is a compression neuropathy affecting the median nerve in the wrist, leading to symptoms like numbness and tingling in the hand, but it does not cause progressive muscle weakness and wasting like muscular dystrophy does.

2. Which hormone is responsible for the characteristic changes experienced during puberty, such as breast development and menstruation in females?

A. Follicle-stimulating hormone (FSH)
B. Luteinizing hormone (LH)
C. Estrogen
D. Progesterone

Correct answer: C

Rationale: The correct answer is C: Estrogen. Estrogen plays a crucial role in regulating the development of secondary sexual characteristics during puberty in females. It is responsible for breast development, widening of hips, and the onset of menstruation. Estrogen is mainly produced by the ovaries and is essential for the maturation of the reproductive system. Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are pituitary hormones that regulate the menstrual cycle and ovulation but do not directly cause the characteristic changes seen during puberty. Progesterone is another hormone involved in the menstrual cycle and pregnancy but is not primarily responsible for the physical changes during puberty.

3. Which sentence uses the past perfect tense correctly?

A. By the time I arrived, the party had already begun.
B. I wish I had studied harder for the exam.
C. We will have finished the project by Monday.
D. She had been waiting for hours before he finally showed up.

Correct answer: A

Rationale: Option A expresses an action ("party began") completed before another past action ("I arrived").

4. The primary function of the respiratory system is to:

A. Maintain body temperature
B. Deliver oxygen to the bloodstream and remove carbon dioxide
C. Produce antibodies for the immune system
D. Break down food molecules for energy

Correct answer: B

Rationale: The correct answer is B: 'Deliver oxygen to the bloodstream and remove carbon dioxide.' The primary function of the respiratory system is to facilitate gas exchange. When we breathe in, oxygen is inhaled and transported to the bloodstream, where it is delivered to cells for energy production. Simultaneously, carbon dioxide, a waste product of cellular metabolism, is removed from the bloodstream and exhaled. This process is vital for sustaining life and maintaining proper oxygen levels in the body. The respiratory system does not primarily regulate body temperature, produce antibodies, or break down food molecules for energy, making options A, C, and D incorrect.

5. Which of the following is the best guarantee that the patientâ€™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.

6. As a young manager, she knows that conflict occurs in any organization. Which of the

A. Can be destructive if the level is too high
B. Is not beneficial; hence it should be prevented at all times
C. May result in poor performance
D.

Correct answer: C

Rationale: Conflict in an organization is a natural occurrence that can either be constructive or destructive. Option C is the correct answer because conflict may indeed lead to poor performance if not managed effectively. When conflict is left unresolved or unaddressed, it can create tension, decrease morale, and hinder productivity. By recognizing that conflict can impact performance, the young manager can take proactive steps to address and resolve conflicts in a constructive manner to minimize its negative effects and promote a healthy work environment.
