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. Considering the statement that communication is most effective when barriers are first removed, which of the following is recognized as an inhibiting factor in communication?

• A. Avoidance of universally accepted abbreviations
• B. Usage of incorrect grammar
• C. Poor handwriting
• D. Advanced age of the client

Correct answer: D

Rationale: The correct answer is 'D: Advanced age of the client.' Age can be a significant obstacle in communication due to factors such as hearing loss, cognitive decline, or memory issues, which all can hamper effective communication. Choices A, B, and C, while they may present challenges in communication, are not directly related to age and its influence on communication, making them incorrect. The issues presented by not using universally accepted abbreviations, incorrect grammar, and poor handwriting can be resolved through clarification, education, or the use of alternative communication methods, unlike the difficulties that can arise from advanced age.

3. Nutritional goals for a patient wishing to modify eating patterns should adhere to each, except one. Which is the exception?

• A. Measurable
• B. Immediate
• C. Realistic
• D. Achievable

Correct answer: B

Rationale: Nutritional goals should be measurable, realistic, and achievable. They should not be immediate, as sustainable changes take time.

4. Select all that apply. A person who is deficient in vitamin A could consume which of the following to increase vitamin A levels?

• A. cantaloupe
• B. eggs
• C. carrots
• D. all of the above

Correct answer: D

Rationale: Vitamin A can be found in high amounts in foods like cantaloupe, eggs, carrots, and milk, all of which help to maintain healthy vision, skin, and immune function.

5. 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.
