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. During the acute phase of a burn, the priority nursing intervention in caring for this client is:
- A. Prevention of infection
- B. Pain management
- C. Prevention of bleeding
- D. Fluid resuscitation
Correct answer: D
Rationale: During the acute phase of a burn, fluid resuscitation is the priority nursing intervention. This phase is characterized by fluid loss and the risk of hypovolemic shock. Administering fluids is crucial to maintain perfusion and prevent complications such as organ failure. While prevention of infection, pain management, and prevention of bleeding are important aspects of burn care, fluid resuscitation takes precedence in the acute phase to stabilize the client's condition and prevent further damage.
3. The Acceptable Macronutrient Distribution Ranges state that half of your calories should come from protein.
- A. TRUE
- B. FALSE
- C.
- D.
Correct answer: B
Rationale: The statement is FALSE. The Acceptable Macronutrient Distribution Ranges recommend that 10-35% of daily calories come from protein, not half. The remaining calories should be derived from a combination of carbohydrates and fats to ensure a balanced diet. Choosing option A is incorrect because it misinterprets the recommended percentage for protein intake. Options C and D are left blank as they are not applicable to the question.
4. A client receiving total parenteral nutrition (TPN is awaiting the next container. What fluid should the nurse infuse in the interim?
- A. Dextrose 5% in water
- B. 0.9% sodium chloride
- C. Dextrose 10% in water
- D. Lactated Ringer's solution
Correct answer: B
Rationale: The correct answer is 0.9% sodium chloride. When a client receiving TPN is awaiting the next container, infusing 0.9% sodium chloride is the appropriate choice to maintain fluid and electrolyte balance. Dextrose solutions are not recommended as they do not provide sufficient nutrition. Lactated Ringer's solution contains electrolytes but lacks essential nutrients found in TPN, making it an inadequate choice during the delay in TPN delivery.
5. Which hormone is produced in fat tissue and helps regulate body fat by suppressing appetite?
- A. glucagon
- B. ghrelin
- C. leptin
- D. insulin
Correct answer: C
Rationale: The correct answer is C, leptin. Leptin is a hormone produced by fat cells that helps regulate energy balance by suppressing hunger, thus aiding in the regulation of body fat. Glucagon (choice A) is a hormone that raises blood glucose levels, ghrelin (choice B) stimulates appetite, and insulin (choice D) regulates blood sugar levels and promotes glucose uptake.
