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. Earliest sign of skin reaction to radiation therapy is:

• A. desquamation
• B. erythema
• C. atrophy
• D. pigmentation

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

3. Theresa, a mother with a 2-year-old daughter, asks, 'At what age can I start taking my daughter's blood pressure as a routine procedure, since hypertension is common in our family?' What would your answer be?

• A. At 2 years old, you may
• B. As early as 1 year old
• C. When she's 3 years old
• D. When she's 6 years old

Correct answer: D

Rationale: Regular blood pressure checks generally start from age 3, but in the case of a family history of hypertension, they should start when the child is around 6 years old. This is because the readings will be more reliable and indicative of the child's health condition at this age. The other options are incorrect because they suggest earlier ages for routine blood pressure checks. While blood pressure can be measured at any age, it is not typically included as part of a routine health check-up for very young children unless there are specific health concerns.

4. A client with iron deficiency anemia is being taught about dietary recommendations by a nurse. Which of the following dietary recommendations should the nurse include as a food that enhances iron absorption when consumed with nonheme iron?

• A. Tomato juice
• B. Tea
• C. Milk
• D. Dried Beans

Correct answer: A

Rationale: Tomato juice is the correct answer because it contains vitamin C, which enhances the absorption of nonheme iron. Vitamin C helps convert nonheme iron into a form that is easier for the body to absorb. Tea and milk should be avoided when consuming nonheme iron as they can inhibit iron absorption. Dried beans, although a good source of iron, do not enhance iron absorption when consumed with nonheme iron.

5. Which nursing diagnosis is a priority for clients with Borderline personality disorder?

• A. Risk for injury
• B. Ineffective individual coping
• C. Altered thought process
• D. Sensory perceptual alteration

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.
