Anatomy

1. Long-term potentiation (LTP) is a process in the brain associated with:

Correct answer: D

Rationale: Long-term potentiation (LTP) is a process in the brain that is primarily associated with memory formation. During LTP, the strength of synaptic connections between neurons is increased, which is crucial for encoding and storing memories. While sensory perception, muscle control, and emotional regulation involve different brain processes, LTP specifically plays a key role in the formation and retention of memories. Therefore, the correct answer is B: Memory formation.

2. Which type of wave requires a medium to travel through?

Correct answer: d

Rationale: Both mechanical waves (such as sound waves) and electromagnetic waves (like light) have different requirements for propagation, but both can travel through a medium.

3. What is the primary hormone released by the parathyroid glands?

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).

4. Following a successful heart transplant surgery, the patient's body will need to take medications to:

Correct answer: A

Rationale: The correct answer is A: 'Suppress the immune system and prevent rejection of the new heart.' After a heart transplant surgery, the body's immune system may recognize the new heart as a foreign object and try to attack it, leading to rejection. To prevent this, patients need to take medications that suppress the immune system, helping the body accept the new heart. These medications are crucial to ensure the success and longevity of the transplanted organ by reducing the risk of rejection. Options B, C, and D are not directly related to the post-heart transplant medication regimen and do not address the primary concern of preventing rejection.

5. The phrase "survival of the fittest" refers to:

Correct answer: B

Rationale: Rationale: The phrase "survival of the fittest" is often associated with the concept of natural selection, which was proposed by Charles Darwin. Natural selection is the process by which organisms that are best adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation. This process does not necessarily favor the most complex anatomical structures (option A) or the strongest and most aggressive individuals (option D). Instead, it emphasizes the importance of adaptations that enhance an organism's ability to survive and reproduce in a specific environment. Option C is incorrect because natural selection results in differential reproductive success based on an organism's traits, meaning that not all organisms have an equal probability of survival and reproductive success.

6. Ms. Valencia develops the standards to be followed. Among the following standards, which is

Correct answer: C

Rationale: The correct answer is C because it is a clear and specific standard that can be easily measured and monitored. Weight recording is a fundamental aspect of patient care and is essential for tracking changes in health status. Verbalized satisfaction (option A) is subjective and may not be consistently measurable. Rotation of duty (option B) is important but may not be a standard developed by a nurse manager. Answering an evaluation form before discharge (option D) is important but may not be a standard created by Ms. Valencia for all patients.
