1. What are direct effects of antibodies? (Select ONE that does not apply):

• A. Neutralization
• B. Agglutination
• C. Precipitation
• D. Phagocytosis

Correct answer: D

Rationale: The direct effects of antibodies include neutralization, agglutination, and precipitation. Antibodies neutralize pathogens by binding to them and preventing their harmful effects. Agglutination involves the clumping together of pathogens, making it easier for phagocytes to engulf them. Precipitation refers to the process where antibodies bind to soluble antigens, forming large complexes that are easily removed from the body. Phagocytosis, on the other hand, is an indirect effect of antibodies where phagocytes engulf and destroy pathogens opsonized by antibodies, not a direct effect.

2. A patient with a history of cardiovascular disease is being prescribed hormone replacement therapy (HRT). What should the nurse include in the patient education regarding the risks associated with HRT?

• A. HRT may increase the risk of cardiovascular events, including heart attack and stroke.
• B. HRT may decrease the risk of osteoporosis.
• C. HRT may increase the risk of venous thromboembolism.
• D. HRT may decrease the risk of breast cancer.

Correct answer: A

Rationale: The correct answer is A. Hormone replacement therapy (HRT) is associated with an increased risk of cardiovascular events, including heart attack and stroke, especially in patients with a history of cardiovascular disease. Choice B is incorrect because HRT does not decrease the risk of osteoporosis; in fact, it may increase the risk of certain conditions like venous thromboembolism, as mentioned in choice C. Choice D is also incorrect as HRT has been associated with a slight increase in the risk of breast cancer.

3. What causes osteoporosis?

• A. Poor nutrition in infancy
• B. Regularly weight-bearing exercise
• C. Bone loss, frequently during aging
• D. Cerebral palsy and associated disorders

Correct answer: C

Rationale: The correct answer is C. Osteoporosis is commonly caused by bone loss that occurs with aging, leading to brittle bones. Choice A, poor nutrition in infancy, is not a direct cause of osteoporosis. Choice B, regularly weight-bearing exercise, actually helps in maintaining bone density and strength, reducing the risk of osteoporosis. Choice D, cerebral palsy and associated disorders, is not a common cause of osteoporosis.

4. A patient being treated for tuberculosis is determined to be drug resistant. Which of the following medications will the patient be resistant to in the treatment of tuberculosis?

• A. Isoniazid (INH) and rifampin
• B. Carbamazepine (Tegretol) and phenytoin (Dilantin)
• C. Dextroamphetamine (Dexedrine) and doxapram (Dopram)
• D. Propranolol (Inderal) and sotalol (Betapace)

Correct answer: A

Rationale: In the treatment of tuberculosis, drug resistance commonly develops against medications like Isoniazid (INH) and rifampin. These two drugs are key components of the standard anti-tuberculosis treatment regimen. Choices B, C, and D are unrelated medications that are not used in the treatment of tuberculosis. Carbamazepine and phenytoin are anticonvulsants, dextroamphetamine is a stimulant, and propranolol and sotalol are used for cardiovascular conditions.

5. Which of the following birthmarks usually fade or regress as the child gets older?

• A. Hemangiomas
• B. Congenital dermal melanocytosis (i.e., Mongolian spots)
• C. Macular stains
• D. Hemangiomas, congenital dermal melanocytosis (i.e., Mongolian spots), and macular stains

Correct answer: D

Rationale: The correct answer is D. Hemangiomas, congenital dermal melanocytosis (i.e., Mongolian spots), and macular stains are birthmarks that usually fade or regress as the child gets older. Hemangiomas are vascular birthmarks that often shrink and fade over time. Congenital dermal melanocytosis (Mongolian spots) are blue-gray birthmarks commonly found on the lower back and buttocks of infants, which typically fade by adolescence. Macular stains, also known as salmon patches, are pink or red birthmarks that usually fade within the first few years of life. Choice D is correct because all the mentioned birthmarks tend to diminish as the child grows, unlike choices A, B, and C which do not fade or regress with age.
