What is the purpose of a chest tube after a lobectomy procedure, as understood by the nurse?
- A. Prevent mediastinal shift
- B. Promote chest expansion of the remaining lung
- C. Drain fluids and blood accumulated post-operatively
- D. Remove the air in the lungs to promote lung expansion
Correct Answer: C
Rationale: After a lobectomy, a chest tube is typically inserted to drain fluids and blood that may have accumulated post-operatively. This tube helps to prevent complications, such as infections or pneumonia, and aids in patient recovery. While a chest tube may aid in preventing a mediastinal shift (Choice A), promoting chest expansion of the remaining lung (Choice B), and removing air in the lungs to promote lung expansion (Choice D), these are not the primary reasons for its use after a lobectomy. Therefore, Choices A, B, and D are incorrect.

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.
Which breakfast items indicate an understanding of foods high in antioxidants A and C?
- A. Fried eggs, sausage, and whole wheat toast
- B. Oatmeal with blueberries and coffee
- C. Cereal with strawberries and low-fat milk
- D. Hard-boiled eggs, cantaloupe, and orange juice
Correct Answer: D
Rationale: The correct answer is D: Hard-boiled eggs, cantaloupe, and orange juice. Cantaloupe and orange juice are rich in vitamins A and C, which are known for their antioxidant properties. Choice A is incorrect because fried eggs, sausage, and whole wheat toast do not contain high levels of antioxidants A and C. Choice B is incorrect because, while blueberries are high in antioxidants, coffee does not provide significant amounts of vitamins A and C. Choice C is incorrect because, although strawberries are a good source of vitamin C, low-fat milk does not contribute significantly to vitamins A and C.
Which food is a reliable source of B12 for a pregnant vegan client?
- A. Soybeans
- B. Algae
- C. Fortified soy milk
- D. Sea vegetables
Correct Answer: C
Rationale: Fortified soy milk is a reliable source of vitamin B12 for pregnant vegan clients as it is usually enriched with this vitamin. The other options, while nutritious, are not reliable sources of B12 for vegans. Soybeans may not provide enough B12, algae contains B12 analogs that the human body cannot utilize, and the B12 content in sea vegetables can fluctuate, potentially not providing the necessary daily intake.
What is the term for a state of disequilibrium wherein a person cannot readily solve a problem or situation using their usual coping mechanisms?
- A. Crisis
- B. Mental health
- C. Mental illness
- D. Stress
Correct Answer: A
Rationale: In psychological terms, a 'Crisis' refers to a state of disequilibrium wherein a person cannot readily solve a problem or situation even by using his usual coping mechanisms. This is different from 'Mental Illness' (Choice C) which is a more general term for a wide range of mental health conditions that affect mood, thinking and behavior. 'Mental Health' (Choice B) is a state of well-being in which an individual realizes his or her own abilities, can cope with the normal stresses of life, can work productively and is able to make a contribution to his or her community. Finally, 'Stress' (Choice D) is a state of mental or emotional strain or tension resulting from adverse or demanding circumstances, but it does not necessarily disrupt equilibrium to the extent that usual coping mechanisms are ineffective, unlike 'Crisis'.
What is the fundamental difference between nursing diagnoses and collaborative problems?
- A. Collaborative problems are managed by nurses using physician-prescribed interventions.
- B. Collaborative problems can be addressed by independent nursing interventions.
- C. Physician-prescribed interventions are incorporated into nursing diagnoses.
- D. Nursing diagnoses include physiologic complications that nurses monitor to detect status changes.
Correct Answer: B
Rationale: The correct answer is B, as collaborative problems necessitate the collective expertise and skills of numerous healthcare professionals, including nurses. These problems can be dealt with through independent nursing interventions in cooperation with other team members. Option A is incorrect because collaborative problems aren't strictly managed with physician-prescribed interventions. Option C is incorrect because nursing diagnoses aim at identifying and treating actual or potential health issues, rather than merely integrating physician-prescribed interventions. Option D is incorrect because nursing diagnoses aim at identifying patient issues, not solely physiologic complications, and guide the necessary nursing care, not just monitor for changes.
