Nursing Elites

1. An obstetrician tells a 42-year-old patient that she can have a healthy baby, but that she is of 'advanced maternal age.' The patient is so upset that she fails to listen to the rest of the doctor's advice, goes home in a huff, and immediately dyes her hair.

• A. the age of the sperm.
• B. the age of her eggs.
• C. her risk of developing diabetes.
• D. her cholesterol level, not her appearance.

Correct answer: B

Rationale: The correct answer is 'the age of her eggs.' As women age, the quality of their eggs decreases, leading to a higher risk of chromosomal abnormalities and infertility. This decline in egg quality is why advanced maternal age is associated with a higher risk of certain pregnancy complications. Choices A, C, and D are incorrect because the primary concern in this context is related to the age-related changes in a woman's eggs, not sperm, diabetes risk, or cholesterol levels.

2. Are kidneys part of the lymphatic system?

• A. TRUE
• B. FALSE
• C. Not Sure
• D. None of the above

Correct answer: B

Rationale: The correct answer is False. Kidneys are not part of the lymphatic system; they are part of the urinary system. The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste, and other unwanted materials. Therefore, choices A, C, and D are incorrect because kidneys are not associated with the lymphatic system.

3. The maintenance of a steady body temperature in the face of fluctuating environmental conditions illustrates homeostasis.

• A. TRUE
• B. FALSE
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: The correct answer is True. Homeostasis is the body's ability to maintain a stable internal environment despite external changes. In this case, the maintenance of a steady body temperature despite fluctuations in environmental conditions is a clear example of homeostasis. The body regulates temperature through processes like sweating when it's hot and shivering when it's cold. Choices B, C, and D are incorrect because the statement provided does indeed illustrate the concept of homeostasis, making them inaccurate.

4. The term 'physiology' is related to

• A. the Latin meaning of 'physical shape.'
• B. the structure of internal organs.
• C. the Greek for 'cutting up.'
• D. the Greek for 'relationship to nature.'

Correct answer: D

Rationale: The term 'physiology' originates from the Greek words 'physis' (meaning nature) and 'logos' (meaning study or relationship). Therefore, the correct answer is 'the Greek for 'relationship to nature.' Choice A is incorrect as it refers to the Latin meaning of 'physiology,' not the Greek origin. Choice B is incorrect as it is specific to the structure of internal organs, not the overall study of nature. Choice C is incorrect as it refers to a different term related to dissection or anatomy, not physiology.

5. What is homeostasis?

• A. The inability to keep body weight within normal limits.
• B. Room temperature decreasing because a window is open.
• C. Ingestion of more food than needed.
• D. The tendency of the body to maintain a stable internal environment.

Correct answer: D

Rationale: The correct answer is D: Homeostasis refers to the body's ability to maintain a stable internal environment despite external changes. Choices A, B, and C are incorrect. Choice A describes obesity, choice B describes a specific scenario with room temperature, and choice C refers to overeating, which is not related to homeostasis.
