Nursing Elites

1. Each statement is true of proteins, except one. Which is the exception?

• A. Proteins are composed of building blocks called amino acids
• B. The classification of the 20 common amino acids is based on the properties of their side chains
• C. The general structure of an amino acid varies considerably
• D. Amino acids polymerize to form long chains called polypeptides

Correct answer: B

Rationale: The correct answer is B. The classification of the 20 common amino acids is not based on the properties of their side chains, but rather on the structure of their amino and carboxyl groups. These groups are consistent among all amino acids, while the side chains, also known as R groups, are what vary and give each amino acid its unique properties. Choice A is correct because proteins are indeed composed of amino acids. Choice C is incorrect because while the side chains of amino acids can vary, the general structure of an amino acid - a central carbon atom bonded to an amino group, a carboxyl group, a hydrogen atom, and a side chain - is consistent. Choice D is correct because amino acids do polymerize to form long chains called polypeptides, which can then fold into complex shapes to form proteins.

2. The RR nurse should monitor for the most common postoperative complication of:

• A. hemorrhage
• B. endotracheal tube perforation
• C. osopharyngeal edema
• D. epiglottis

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 of the following is not true about Pure Experimental research?

• A. There is a control group
• B. There is an experimental group
• C. Selection of subjects in the control group is randomized
• D. There is a careful selection of subjects in the experimental group

Correct answer: D

Rationale: In Pure Experimental research, subjects in the experimental group are typically selected randomly to minimize bias and ensure that the results are attributable to the intervention being studied. Therefore, the statement 'There is a careful selection of subjects in the experimental group' is not true. This careful selection would introduce bias and compromise the validity of the experimental results. Choices A, B, and C are true for Pure Experimental research as it involves both a control group, an experimental group, and randomization of subject selection in the control group to ensure comparability.

4. A common side effect of diuretic medications is _____.

• A. dry mouth
• B. urinary tract infection
• C. increased taste perception
• D. nausea

Correct answer: A

Rationale: Diuretic medications can lead to dry mouth due to increased fluid loss through urination, reducing saliva production.

5. A nurse is providing dietary teaching for a client who has a burn injury and adheres to a vegan diet. The nurse should recommend which of the following foods as the best source of protein to promote wound healing?

• A. One cup of brown rice
• B. One cup of orange juice
• C. One cup of pureed avocado
• D. One cup of lentils

Correct answer: D

Rationale: Lentils are an excellent source of plant-based protein, essential for wound healing in a vegan diet. Brown rice, orange juice, and pureed avocado are not protein-rich foods like lentils and would not provide sufficient protein for wound healing in this scenario.
