Nursing Elites

1. What chronic disease has been associated with increased risks of dental problems?

• A. diabetes mellitus
• B. chronic obstructive pulmonary disease
• C. Addison's disease
• D. asthma

Correct answer: A

Rationale: Diabetes mellitus is associated with an increased risk of dental problems, including gum disease and tooth loss, due to high blood sugar levels. While chronic obstructive pulmonary disease (COPD), Addison's disease, and asthma may have oral health implications, diabetes mellitus is specifically known for its strong association with dental issues.

2. Which of the following conditions is not caused by energy drinks?

• A. Nervousness
• B. Bradycardia
• C. Seizures
• D. Dental caries

Correct answer: B

Rationale: Energy drinks are known for causing a variety of health issues, including nervousness, seizures, and an increased risk of dental caries due to their high sugar content. However, they do not cause bradycardia, which is a slow heart rate. Instead, energy drinks are associated with causing an increased or rapid heart rate, known as tachycardia. Therefore, out of the listed options, bradycardia is the condition not caused by energy drinks.

3. Vitamin deficiencies, especially the B-complex vitamins, seldom occur in isolation. Folate, a B-complex vitamin, is the exception because it functions separately from other vitamins.

• A. Both statements are true.
• B. Both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: C

Rationale: The first statement is true; the second is false. If a deficiency of one vitamin is suspected, symptoms of other vitamin B deficiencies also may be present. Folate deficiencies usually occur with other nutrient deficiencies. Specifically, folate functions in conjunction with vitamins B12 and C in maintaining normal levels of mature red blood cells.

4. In conducting a cleansing enema, how does the nurse position the client?

• A. Right lateral position
• B. Left lateral position
• C. Right Sim's position
• D. Left Sim's position

Correct answer: B

Rationale: In preparing a patient for a cleansing enema, the nurse typically positions the patient in the left lateral position. This position allows for the best flow of the solution due to the anatomical configuration of the colon. The right lateral position, right Sim's position, and left Sim's position are not typically used for this procedure. The rationale provided initially is incorrect as it pertains to lung expansion and postural drainage, which are not relevant to a cleansing enema procedure.

5. 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.
