1. What property is found in clients with metastatic cancer?

• A. Tumors that are well encapsulated
• B. Tumors with slow, stable growth
• C. Cells that are genetically stable
• D. Cells invading local tissue and overrunning neighboring cells

Correct answer: D

Rationale: Metastatic cancer is characterized by cells that invade local tissue and overrun neighboring cells. Therefore, the correct answer is D. Choices A, B, and C are incorrect because metastatic cancer is associated with aggressive behavior where cells invade and spread to other parts of the body, rather than being well encapsulated, growing slowly, or being genetically stable.

2. What is the most sensitive indicator of altered brain function?

• A. The ability to perform complex mathematics
• B. Altered level of consciousness
• C. The lack of cerebrospinal fluid production
• D. Intact cranial nerve functions

Correct answer: B

Rationale: The correct answer is B: Altered level of consciousness. Changes in consciousness are the most sensitive indicator of altered brain function as they can signal underlying neurological issues. Option A, the ability to perform complex mathematics, though it involves brain function, is not as sensitive or direct an indicator as altered consciousness. Option C, the lack of cerebrospinal fluid production, is more related to conditions like hydrocephalus rather than a direct indicator of altered brain function. Option D, intact cranial nerve functions, indicate the normal functioning of peripheral nerves and are not as sensitive to changes in brain function as alterations in consciousness.

3. What is the primary function of the kidneys in acid-base balance?

• A. The kidneys remove hydrogen ions and retain bicarbonate ions.
• B. The kidneys convert ammonia into urea, which is excreted in the urine.
• C. The kidneys produce aldosterone to regulate sodium levels.
• D. The kidneys secrete renin to regulate blood pressure.

Correct answer: A

Rationale: The correct answer is A. The kidneys are crucial in maintaining acid-base balance by removing hydrogen ions to decrease acidity and retaining bicarbonate ions to increase alkalinity. Choice B is incorrect because the conversion of ammonia into urea is related to nitrogen waste excretion, not acid-base balance. Choice C is incorrect as aldosterone regulates sodium levels, not acid-base balance. Choice D is also incorrect as renin is involved in regulating blood pressure, not acid-base balance.

4. A 23-year-old pregnant female visits her primary care provider for her final prenatal checkup. The primary care provider determines that the fetus has developed an infection in utero. Which of the following would be increased in the fetus at birth?

• A. IgG
• B. IgA
• C. IgM
• D. IgD

Correct answer: C

Rationale: The correct answer is IgM. IgM is the first antibody produced in response to an infection and is elevated in a fetus with an in utero infection. IgG is the primary antibody responsible for providing immunity to the fetus and is transferred across the placenta during the third trimester. IgA is mainly found in mucosal areas and colostrum but not significantly elevated in fetal infections. IgD is involved in the development and maturation of B cells but not typically increased in fetal infections.

5. Which of the following stores electrolytes and acts as an electrolyte pool?

• A. Brain - Kidneys
• B. Bone - Nails
• C. Bone - Liver
• D. Liver - Pancreas

Correct answer: B

Rationale: Bones store electrolytes and act as a reservoir, maintaining a balance of essential minerals like calcium and phosphate. The correct pair in this context is 'Bone - Nails.' Choices A, C, and D are incorrect because the brain, kidneys, liver, and pancreas perform other functions in the body and are not primarily responsible for storing electrolytes.
