1. Which type of immunity is demonstrated by the transfer of a mother's immunoglobulin across the placenta to protect the child?

A. Natural active immunity
B. Natural passive immunity
C. Artificial active immunity
D. Artificial passive immunity

Correct answer: B

Rationale: The immunoglobulin passed from the mother to the child through the placenta is an example of natural passive immunity, making choice B the correct answer. This transfer gives the child temporary immunity to various diseases without their immune system having to work. On the other hand, natural active immunity (Choice A) occurs when the body produces its own antibodies in response to an antigen. Artificial active immunity (Choice C) is achieved through vaccinations, where the immune system is stimulated to produce antibodies against a specific disease. Artificial passive immunity (Choice D) is a temporary immunity that involves the transfer of pre-formed antibodies from another source.

2. What are symptoms of uncontrolled type 1 diabetes?

A. Depression, anxiety, and fatigue
B. Increased thirst, urination, and hunger
C. Weight gain, macrosomia, and food cravings
D. Poor wound healing, blurred vision, and recurrent infections

Correct answer: B

Rationale: The correct answer is B: Increased thirst, urination, and hunger. Uncontrolled type 1 diabetes typically presents with classic symptoms including polydipsia (increased thirst), polyuria (frequent urination), and polyphagia (increased hunger). These symptoms are often accompanied by weight loss due to the body's inability to properly utilize glucose for energy. Choices A, C, and D are incorrect as they do not align with the typical symptoms of uncontrolled type 1 diabetes. Depression, anxiety, fatigue, weight gain, macrosomia, food cravings, poor wound healing, blurred vision, and recurrent infections are not primary symptoms associated with uncontrolled type 1 diabetes.

3. When is infertility said to exist?

A. When a woman has no uterus
B. When a woman has no children
C. When a couple has been trying to conceive for 1 year without success
D. When a couple has desired a child for 6 months

Correct answer: C

Rationale: Infertility is defined as not being able to get pregnant despite having frequent, unprotected sex for at least a year for most couples. Therefore, the correct answer is C. A, B, and D are incorrect. While having no uterus (choice A) may result in infertility, it is not the sole determining factor. Similarly, not having children (choice B) does not automatically indicate infertility. Lastly, the time frame of 6 months (choice D) is not sufficient to determine infertility; typically, a year of trying without success is required for such a diagnosis.

4. During the first 24 hours after the thermal injury, you should assess Sergio for:

A. hypokalemia and hypernatremia
B. hypokalemia and hyponatremia
C. hyperkalemia and hyponatremia
D. hyperkalemia and hypernatremia

Correct answer: D

Rationale: During the initial phase after a thermal injury, the major concern is the release of potassium due to cell damage, leading to hyperkalemia. Hypernatremia is not typically a primary concern in the immediate post-injury phase. Hyponatremia is less likely to occur initially after a burn injury. Therefore, the correct assessment for Sergio during the first 24 hours after the thermal injury would be hyperkalemia and hypernatremia.
