Nursing Elites

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. As Leda’s nurse, you plan to set up an emergency equipment at her beside following thyroidectomy. You should include:

• A. An airway and rebreathing tube
• B. A tracheostomy set and oxygen
• C. A crush cart with bed board
• D. Two ampules of sodium bicarbonate

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.

3. An adolescent client has bloodshot eyes, a voracious appetite, and dry mouth. Which drug abuse would the nurse most likely suspect?

• A. Marijuana
• B. Amphetamines
• C. Barbiturates
• D. Anxiolytics

Correct answer: A

Rationale: The symptoms described, including bloodshot eyes, a voracious appetite, and dry mouth, are consistent with marijuana use. Bloodshot eyes are a common side effect of marijuana due to its effect on blood vessels in the eyes. Marijuana also often causes an increase in appetite (known as 'the munchies') and can result in dry mouth. Amphetamines typically cause symptoms like increased alertness, energy, and decreased appetite. Barbiturates and anxiolytics would not typically cause bloodshot eyes, a voracious appetite, and dry mouth as described in the scenario. Therefore, the most likely drug abuse the nurse would suspect in this case is marijuana.

4. A nurse in a prenatal clinic is educating a client about expected changes during pregnancy. The nurse should instruct the client about which change during pregnancy is related to the slowing of the gastrointestinal tract?

• A. Diarrhea
• B. Constipation
• C. Decreased absorption of iron
• D. Decreased absorption of calcium

Correct answer: B

Rationale: During pregnancy, the hormonal changes can lead to the slowing down of the gastrointestinal tract, causing constipation. This occurs due to increased progesterone levels, which relax smooth muscles, including those in the intestines, leading to slower bowel movements. Diarrhea is not typically associated with the slowing of the gastrointestinal tract during pregnancy. While there may be changes in the absorption of nutrients like iron and calcium, they are not directly related to the slowing of the gastrointestinal tract.

5. A nurse is developing an education program for a community group about dietary intake of vitamins and minerals in the diet. The nurse should include which of the following foods as sources of vitamin C? (Select the food that does not apply.)

• A. Green pepper
• B. Orange
• C. Cabbage
• D. Milk

Correct answer: D

Rationale: The correct answer is E: Milk. Milk is not a significant source of vitamin C. Choices A, B, C, and D are all good sources of vitamin C. Green pepper, orange, cabbage, and strawberries contain vitamin C and can be included in the diet to meet the body's need for this essential vitamin. Milk, on the other hand, is not known for its vitamin C content, so it does not apply as a source of this particular vitamin.
