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. The lobe of the brain that contains the auditory receptive areas is the ____________ lobe.
- A. temporal
- B. frontal
- C. parietal
- D. occipital
Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
3. After cleaning the abrasions and applying antiseptic, the nurse applies a cold compress to the swollen ankle as ordered by the physician. This statement shows that the nurse has a correct understanding of the use of a cold compress:
- A. Cold compress reduces blood viscosity in the affected area
- B. It is safer to apply than a hot compress
- C. Cold compress prevents edema and reduces pain
- D. It eliminates toxic waste products due to vasodilation
Correct answer: C
Rationale: The correct understanding of using a cold compress includes knowing that it helps prevent edema and reduces pain. Cold application constricts blood vessels, reducing blood flow to the area, which helps decrease swelling and pain. Choices A, B, and D are incorrect because cold compresses do not directly affect blood viscosity, safety compared to hot compresses, or eliminate toxic waste products due to vasodilation. It is essential for nurses to have a clear understanding of the rationale behind interventions to provide effective patient care.
4. A healthcare professional is reviewing the lab findings of a client who has Clostridium Difficile. Which of the following findings should indicate to the healthcare professional that the client is experiencing Fluid Volume Deficit?
- A. Hct 53%
- B. Potassium 3.5
- C. Sodium 145
- D. HbA1c 5
Correct answer: A
Rationale: An elevated hematocrit level (Hct 53%) indicates hemoconcentration, a sign of fluid volume deficit. Hct measures the percentage of red blood cells in the blood and increases when there is a decrease in plasma volume, as seen in fluid volume deficit. Choices B, C, and D do not directly relate to fluid volume status. Potassium and sodium levels are more indicative of electrolyte imbalances, while HbA1c reflects average blood sugar levels over the past 2-3 months and is not specific to fluid volume status.
5. An advance directive known as a durable power of attorney involves appointing another person called a(n) _____ to act as the decision maker in the event of the patient's incapacitation.
- A. witness
- B. primary caregiver
- C. health care agent
- D. state proxy
Correct answer: C
Rationale: The correct answer is 'health care agent.' A health care agent is appointed through a durable power of attorney to make medical decisions on behalf of a patient who becomes incapacitated. The term 'witness' (choice A) is incorrect because a witness only observes the signing of the directive and does not make decisions. 'Primary caregiver' (choice B) is also incorrect as they may provide care but are not necessarily legally empowered to make decisions. 'State proxy' (choice D) is not commonly used in the context of advance directives or health care decision making, making it an incorrect choice.
