1. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?
- A. hemoglobin
- B. transferrin
- C. myoglobin
- D. hepcidin
Correct answer: A
Rationale: The correct answer is A: hemoglobin. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. Iron is a crucial component of hemoglobin, binding to oxygen and allowing for its transport. Choice B, transferrin, is involved in iron transport in the blood but not in oxygen transport. Choice C, myoglobin, is a protein found in muscle cells that stores oxygen for muscle use, not transportation in the bloodstream. Choice D, hepcidin, is a peptide hormone that regulates iron absorption in the intestines and iron distribution in the body, but it is not directly involved in oxygen transport.
2. The anatomy of a body part is closely related to its physiology.
- A. True
- B. False
- C. Not Sure
- D. None of the above
Correct answer: A
Rationale: The statement is true. Anatomy and physiology are interconnected fields. Anatomy focuses on the structure of body parts, while physiology deals with the functions of those parts. Understanding the structure (anatomy) of a body part is crucial in comprehending how it functions (physiology). This interrelation is essential for healthcare professionals to diagnose and treat medical conditions effectively. Choice B is incorrect because anatomy and physiology are indeed closely related. Choice C is incorrect as well because the relationship between anatomy and physiology is a fundamental concept in the study of the human body. Choice D is incorrect as the statement is true.
3. A client is being educated by a healthcare provider about managing Digoxin toxicity. Which statement by the client demonstrates an understanding of the teaching?
- A. I will take an extra dose of Digoxin if I miss one.
- B. I should notify my healthcare provider if I experience visual changes.
- C. I will stop taking Digoxin if my heart rate is below 70 bpm.
- D. I should take antacids to alleviate gastrointestinal upset.
Correct answer: B
Rationale: The correct answer is B. Visual changes, such as yellow or blurred vision, can be indicative of digoxin toxicity. It is crucial for clients to inform their healthcare provider promptly if they encounter these symptoms. Prompt medical attention can help manage potential toxicity and prevent complications. Choices A, C, and D are incorrect because taking an extra dose of Digoxin, stopping Digoxin based on heart rate alone, and using antacids for gastrointestinal upset are not appropriate actions when managing Digoxin toxicity.
4. A nurse is instructing the mother of a toddler who has iron-deficiency anemia to increase iron in the child’s diet in addition to the prescribed iron supplement. Which of the following foods should the nurse recommend?
- A. Skim milk
- B. Bananas
- C. Tuna fish
- D. Cucumbers
Correct answer: Tuna fish
Rationale: Tuna fish is a good source of iron and would be beneficial for a toddler with iron-deficiency anemia. Skim milk, bananas, and cucumbers are not significant sources of iron and would not help in increasing the iron levels in the child's diet. Skim milk, in particular, can inhibit iron absorption due to its calcium content, which is important for the nurse to educate the mother about.
5. The ability to adapt successfully to even very difficult circumstances is called ________.
- A. resilience
- B. hardiness
- C. perseverance
- D. a challenge orientation
Correct answer: A
Rationale: Resilience is indeed the correct term for the ability to adapt successfully to difficult circumstances. Resilience involves bouncing back from setbacks, handling stress, and persevering in the face of adversity. Choice B, 'hardiness,' refers more to toughness or durability rather than adapting to difficult circumstances. Choice C, 'perseverance,' is about persistence and determination rather than adaptability. Choice D, 'a challenge orientation,' does not directly relate to the ability to adapt to difficult circumstances, making it an incorrect choice.
