1. Which patient is at greatest risk for papilledema?

A. An elderly patient with cataracts and macular degeneration
B. A male patient with hypothyroidism
C. A male patient with hyperthyroidism
D. An adolescent with a closed head injury

Correct answer: D

Rationale: An adolescent with a closed head injury is at the highest risk for papilledema due to increased intracranial pressure. Papilledema is often a consequence of elevated intracranial pressure, which can occur in conditions like head trauma. Choices A, B, and C do not directly correlate with an increased risk of papilledema compared to a closed head injury, which is more likely to lead to elevated intracranial pressure and subsequent papilledema.

2. Which of the following changes was enacted by the Patient Protection and Affordable Care Act?

A. Creation of national health insurance exchanges for affordable insurance coverage
B. Expansion of school-based health centers
C. Free preventative services for all
D. Medically managed clinics eligible for federal funding

Correct answer: B

Rationale: The correct answer is B. The Patient Protection and Affordable Care Act expanded school-based health centers to provide additional healthcare services to students. Choice A is incorrect because the creation of national health insurance exchanges was a key provision of the Affordable Care Act, but it was not the only change enacted by the legislation. Choice C is incorrect as while the Affordable Care Act did include provisions for free preventative services for certain groups, it was not applicable to all individuals. Choice D is incorrect as the Act did not specifically address medically managed clinics eligible for federal funding.

3. Wilms' tumor is a form of:

A. Renal cancer.
B. Liver cancer.
C. Basal cell carcinoma.
D. Brain cancer.

Correct answer: A

Rationale: Wilms' tumor is a type of kidney cancer that primarily affects children. The correct answer is A: Renal cancer. This tumor originates in the kidneys and is most commonly found in children, with the peak incidence around 3-4 years of age. Choice B, Liver cancer, is incorrect as Wilms' tumor specifically involves the kidneys, not the liver. Choice C, Basal cell carcinoma, is a form of skin cancer, not related to Wilms' tumor. Choice D, Brain cancer, is incorrect as Wilms' tumor is not associated with the brain but rather with the kidneys.

4. Select the stage of shock that is accurately paired with its characteristic.

A. The initial stage of shock: Hyperventilation occurs and the blood pH rises.
B. The compensatory stage of shock: Hypoxia occurs and lactic acid rises.
C. The progressive stage of shock: Histamine is released; fluid and proteins leak into surrounding tissues and the blood thickens.
D. The refractory stage of shock: Potassium ions leak out; sodium ions build up, and metabolic acidosis increases.

Correct answer: C

Rationale: The progressive stage of shock is accurately described as the stage where histamine is released, leading to fluid and proteins leaking into surrounding tissues and the blood thickening. In this stage, the body's compensatory mechanisms are overwhelmed, resulting in a cascade of events that worsen the shock state. Choice A is incorrect as hyperventilation and a rise in blood pH are more characteristic of the compensatory stage. Choice B is incorrect as hypoxia and a rise in lactic acid are more typical of the progressive stage. Choice D is incorrect as the described electrolyte imbalances and metabolic acidosis are more aligned with the refractory stage of shock.

5. Low birth weight is defined as a newborn's weight of:

A. 2500 grams or less at birth, regardless of gestational age.
B. 1500 grams or less at birth, regardless of gestational age.
C. 2500 grams or less at birth, according to gestational age.
D. 1500 grams or less at birth, according to gestational age.

Correct answer: A

Rationale: Low birth weight is defined as 2500 grams or less at birth, regardless of gestational age. This means that any newborn weighing 2500 grams or less is considered to have a low birth weight, irrespective of how many weeks they were in the womb. Choices B, C, and D are incorrect because they specify a weight of 1500 grams or less, which is not the standard definition of low birth weight. The correct definition is 2500 grams or less, not influenced by gestational age.
