1. 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.

2. What is the main function of energy storage technologies in the context of renewable energy?

A. Reduce the cost of producing solar and wind power.
B. Enhance the efficiency of energy transmission and distribution.
C. Compensate for the intermittent nature of renewable energy sources.
D. Eliminate the need for fossil fuels in electricity generation.

Correct answer: C

Rationale: Choice C directly addresses the passage's emphasis on managing the fluctuating availability of renewable energy, hence being the main function of storage technologies.

3. A scientist observes a new species of bird with uniquely shaped wings. They hypothesize that the wing shape allows for superior gliding ability. Which observation would most strongly support this hypothesis?

A. The bird is found in mountainous regions.
B. The bird has feathers with low friction.
C. The bird can fly long distances without flapping.
D. The bird's wing muscles are stronger than other birds.

Correct answer: C

Rationale: Direct observation of gliding ability directly tests the hypothesis about the wing shape's function. Other observations might be relevant but provide less direct evidence.

4. Which of the following is a MAJOR consequence of a stroke?

A. Irregular heart rhythm.
B. Rapid weight gain or loss.
C. Brain damage due to interrupted blood flow.
D. Chronic fatigue and muscle weakness.

Correct answer: C

Rationale: The correct answer is C: 'Brain damage due to interrupted blood flow.' A stroke occurs when there is a sudden interruption in the blood supply to the brain, leading to brain damage. This interruption can result in various consequences such as paralysis, speech and vision problems, cognitive impairments, and in severe cases, even death. Other options like 'Irregular heart rhythm' (A) and 'Chronic fatigue and muscle weakness' (D) can be associated with health conditions but are not direct consequences of a stroke. 'Rapid weight gain or loss' (B) is typically not a major consequence of a stroke compared to the significant impact of brain damage.

5. What is the difference between homologous chromosomes and sister chromatids?

A. Homologous chromosomes have the same genes but may have different alleles, while sister chromatids are identical copies of the same chromosome.
B. Homologous chromosomes are only found in diploid cells, while sister chromatids are found in both haploid and diploid cells.
C. Both homologous chromosomes and sister chromatids are genetically identical, but only sister chromatids separate during mitosis.
D. Both homologous chromosomes and sister chromatids can separate during mitosis, but only homologous chromosomes have different alleles.

Correct answer: A

Rationale: Rationale: - Homologous chromosomes are pairs of chromosomes that have the same genes in the same order, one from each parent. While they carry the same genes, they may have different alleles (variants of a gene). - Sister chromatids are exact copies of each other, formed during DNA replication. They are held together by a centromere and are produced during the S phase of the cell cycle. - During meiosis, homologous chromosomes pair up and exchange genetic material through crossing over, leading to genetic variation. Sister chromatids separate during mitosis to ensure each daughter cell receives an identical copy of the genetic material.

6. What is the medical term for ingrown hair?

A. Folliculitis
B. Hirsutism
C. Pseudofolliculitis Barbae
D. Alopecia

Correct answer: C

Rationale: The correct answer is C: 'Pseudofolliculitis Barbae.' This term specifically refers to ingrown hairs commonly seen in the beard area. Folliculitis (A) is inflammation of the hair follicles, not necessarily due to ingrown hairs. Hirsutism (B) is excessive hair growth, unrelated to ingrown hairs. Alopecia (D) is hair loss, which is also not related to ingrown hairs. Therefore, 'Pseudofolliculitis Barbae' is the medical term specifically used to describe ingrown hairs in the beard area, making it the correct answer.
