1. When the maternal immune system becomes sensitized against antigens expressed by the fetus, what type of immune reaction occurs?

• A. Autoimmune
• B. Anaphylaxis
• C. Alloimmune
• D. Allergic

Correct answer: C

Rationale: When the maternal immune system becomes sensitized against antigens expressed by the fetus, an alloimmune reaction occurs. In this situation, the mother's immune system recognizes the fetus as foreign due to differences in antigens, leading to an immune response against the fetus. Choice A, 'Autoimmune,' is incorrect because it refers to the immune system mistakenly attacking the body's own cells and tissues. Choice B, 'Anaphylaxis,' is not the correct answer as it is a severe allergic reaction that can be life-threatening. Choice D, 'Allergic,' is also incorrect as it refers to an immune response triggered by allergens, not antigens expressed by the fetus.

2. Which of the following is a factor that leads to increased risk for dehydration in the elderly?

• A. More insensible losses
• B. Increase in muscle mass
• C. Decline in kidney function
• D. Decrease in fat

Correct answer: C

Rationale: The correct answer is C: Decline in kidney function. As people age, their kidneys may not work as effectively in conserving water and concentrating urine, leading to a higher risk of dehydration. Choice A is incorrect because more insensible losses do not directly relate to an increased risk of dehydration in the elderly. Choice B, an increase in muscle mass, is not a factor that leads to dehydration. Choice D, a decrease in fat, is also not a direct factor contributing to dehydration in the elderly.

3. 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.

4. A female patient is concerned about the side effects of hormone replacement therapy (HRT). What common side effect should the nurse explain?

• A. Weight gain
• B. Hair loss
• C. Increased libido
• D. Decreased energy levels

Correct answer: A

Rationale: The correct answer is A: Weight gain. Weight gain is a common side effect of hormone replacement therapy (HRT) due to hormonal changes. Patients should be informed about this possibility as part of their treatment plan. Hair loss (Choice B) is not a common side effect of HRT. Increased libido (Choice C) and decreased energy levels (Choice D) are not typically associated with HRT side effects. Therefore, the nurse should focus on discussing weight gain with the patient.

5. In the ED, a homeless client is brought in with severe hypothermia. The police officers also state that they found a 'bottle of booze' on the sidewalk next to him. This puts the nurse on high alert since alcohol contributes to hypothermia by:

• A. interfering with the appetite center in the brain, causing the person to not respond to hunger cues.
• B. causing the person to have less insulation from body fat.
• C. dulling mental awareness, impairing judgment to seek shelter.
• D. increasing the basal metabolic rate, leading to faster depletion of ATP.

Correct answer: C

Rationale: Alcohol impairs judgment and dulls mental awareness, making a person less likely to seek shelter when experiencing hypothermia. This impaired judgment can lead to risky behaviors that exacerbate the effects of cold exposure. Choice A is incorrect because alcohol does not directly interfere with the appetite center in the brain to the extent described. Choice B is incorrect as alcohol consumption does not directly impact the amount of body fat present. Choice D is incorrect because alcohol does not increase the basal metabolic rate but rather slows it down.
