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 correct temperature to store vaccines in a refrigerator is:

• A. between -4 deg C and +8 deg C
• B. between 2 deg C and +8 deg C
• C. between -8 deg C and 0 deg C
• D. between -8 deg C and +4 deg C

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. Baby John develops hyperbilirubinemia. What is a method used to treat hyperbilirubinemia in a newborn?

• A. Keeping infants in a warm and dark environment
• B. Administration of cardiovascular stimulant
• C. Gentle exercise to stop muscle breakdown
• D. Early feeding to speed passage of meconium

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

4. Does the reduction in oxidative damage that occurs with energy restriction in animals also occur in people whose diets include _____?

• A. fiber and carbohydrates
• B. fatty acids and protein
• C. probiotics
• D. antioxidants and phytochemicals

Correct answer: D

Rationale: The correct answer is 'antioxidants and phytochemicals'. Antioxidants and phytochemicals help reduce oxidative damage in the body, contributing to healthy aging and a lower risk of chronic diseases. This is the same effect observed in animals when their energy intake is restricted. The other choices are incorrect as there is no direct evidence connecting reduced oxidative damage with diets high in fiber and carbohydrates, fatty acids and protein, or probiotics.

5. Approximately 70 to 80 percent of acute pancreatitis cases are caused by gallstones or _____.

• A. infection
• B. alcohol abuse
• C. diabetes
• D. obesity

Correct answer: B

Rationale: Alcohol abuse is indeed a major cause of acute pancreatitis, along with gallstones, accounting for the majority of cases. While infections, diabetes, and obesity can also contribute to pancreatitis, they are not as prevalent as alcohol abuse and gallstones in causing acute pancreatitis.
