Nursing Elites

1. You are a researcher testing out the effects of a new food molecule—MEGA—on bone health. In order to know if it actually travels to bone cells in the body, you first need to find out if it gets absorbed in the bloodstream. You eat a food containing MEGA, and you measure the molecule in your urine and feces. You only detect MEGA in the feces. Was MEGA absorbed?

• A. No—absorbed compounds show up in urine, not feces
• B. Yes—absorbed compounds show up in feces, not urine
• C.
• D.

Correct answer: A

Rationale: If MEGA was only detected in feces and not in urine, it was not absorbed into the bloodstream. Absorbed compounds typically appear in urine after processing by the body. The correct answer is A because the presence of a compound in feces indicates that it was not absorbed by the body and passed through the digestive system. Choices B, C, and D are incorrect as they do not align with the process of absorption and excretion in the body.

2. Transmission of HIV from an infected individual to another person occurs:

• A. Most frequently in nurses with needlesticks
• B. Only if there is a large viral load in the blood
• C. Most commonly as a result of sexual contact
• D. In all infants born to women with HIV infection

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. Which list contains fatty acids that reduce cardiovascular disease risk?

• A. omega 3, trans fatty acids, saturated fatty acids
• B. EPA and DHA
• C. omega 6, omega 3, partially hydrogenated oil
• D. omega 3, EPA, saturated fatty acids

Correct answer: B

Rationale: EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), both omega-3 fatty acids, are known to reduce the risk of cardiovascular disease.

4. Begins carb digestion in the mouth:

• A. pepsin
• B. salivary amylase
• C. CCK
• D. secretin

Correct answer: B

Rationale: Salivary amylase is the enzyme that begins the digestion of carbohydrates in the mouth by breaking down starches into simpler sugars.

5. What is the most important concern immediately after a myocardial infarction?

• A. Reducing cholesterol intake
• B. Allowing cardiac rest for healing
• C. Reducing saturated fat intake
• D. Eating several small meals each day

Correct answer: B

Rationale: Immediately after a myocardial infarction, the primary concern is to allow the heart to rest and heal to prevent further damage. This is why choice B is the correct answer. While choices A, C, and D might be a part of the long-term management plan following a myocardial infarction, they are not the immediate priority. Reducing cholesterol and saturated fat intake, as well as adjusting eating habits can help prevent future heart issues, but do not directly contribute to the immediate recovery post-myocardial infarction.
