1. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?

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. In PEM, which condition is characterized by symptoms such as muscle weakness, hanging skin, delayed tooth eruption, and changes in saliva?

Correct answer: A

Rationale: The correct answer is Marasmus. Marasmus is a severe form of protein-energy malnutrition (PEM) that leads to muscle wasting, hanging skin, delayed growth, and changes in saliva. These symptoms are commonly seen in vulnerable populations such as children, homeless individuals, older adults, and substance abusers. Kwashiorkor, on the other hand, is characterized by edema, a distended belly, and skin lesions. Anemia is a condition characterized by a low red blood cell count, leading to fatigue and weakness. Noma is a severe infection affecting the face, particularly the mouth and jaw area.

3. A client is following Seventh-Day Adventist dietary laws. Which of the following dietary guidelines should the nurse include in the plan of care?

Correct answer: B

Rationale: Seventh-Day Adventists typically avoid stimulants like caffeine, so requesting that coffee be removed from meal trays is appropriate. Choice A is incorrect because it does not specifically relate to Seventh-Day Adventist dietary guidelines. Choice C is incorrect as pork is generally avoided in Seventh-Day Adventist dietary laws. Choice D is incorrect as it does not address the specific dietary preferences of Seventh-Day Adventist clients.

4. While evaluating the meal choices of a client with major depressive disorder and a prescription of Phenelzine, which of the following selections should the nurse identify as appropriate?

Correct answer: C

Rationale: The correct answer is C, 'Strawberry yogurt.' This choice is appropriate because it does not contain high levels of tyramine, which can lead to a dangerous interaction with Phenelzine, a monoamine oxidase inhibitor. Tyramine-rich foods, like aged cheeses (such as cheddar cheese) and cured meats (like smoked salmon and pepperoni), should be avoided by individuals taking Phenelzine to prevent hypertensive crisis. Strawberry yogurt is a safer option for the client in this scenario.

5. Mang David, A 27 year old psychiatric client was admitted with a diagnosis of schizophrenia. During the morning assessment, Mang David shouted “Did you know that I am the top salesman in the world? Different companies want me!” As a nurse, you know that this is an example of:

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
