Nursing Elites

1. After cleaning the abrasions and applying antiseptic, the nurse applies a cold compress to the swollen ankle as ordered by the physician. This statement shows that the nurse has a correct understanding of the use of a cold compress:

• A. Cold compress reduces blood viscosity in the affected area
• B. It is safer to apply than a hot compress
• C. Cold compress prevents edema and reduces pain
• D. It eliminates toxic waste products due to vasodilation

Correct answer: C

Rationale: The correct understanding of using a cold compress includes knowing that it helps prevent edema and reduces pain. Cold application constricts blood vessels, reducing blood flow to the area, which helps decrease swelling and pain. Choices A, B, and D are incorrect because cold compresses do not directly affect blood viscosity, safety compared to hot compresses, or eliminate toxic waste products due to vasodilation. It is essential for nurses to have a clear understanding of the rationale behind interventions to provide effective patient care.

2. What instruction should the nurse include on weight gain during pregnancy?

• A. Failure to obtain the required weight gain during pregnancy will increase the risk of preterm birth.
• B. An obese client needs to gain as much weight as a client with a normal body mass index.
• C. A client with a normal body mass index should plan on gaining 50 pounds.
• D. Clients will need to eat for two when they are pregnant.

Correct answer: A

Rationale: Appropriate weight gain is crucial for reducing the risk of preterm birth.

3. 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.

4. Which of the following nutrients deficiency may lead to a diabetes-like condition?

• A. chromium
• B. iron
• C. molybdenum
• D. selenium

Correct answer: A

Rationale: Chromium is essential for proper glucose metabolism. A deficiency in chromium can result in insulin resistance, which shares similarities with diabetes. Iron, molybdenum, and selenium deficiencies do not directly lead to a diabetes-like condition. Iron deficiency causes anemia, molybdenum deficiency is rare and can lead to specific metabolic issues, and selenium deficiency may result in thyroid problems but not a diabetes-like condition.

5. A nurse is teaching a parent about appropriate snack choices for her 9-month-old infant. Which of the following food choices should the nurse recommend?

• A. Skim milk
• B. Unsalted popcorn
• C. Graham crackers
• D. Raw carrots

Correct answer: C

Rationale: Graham crackers are an appropriate snack choice for a 9-month-old infant due to their texture and ease of consumption. Skim milk (Choice A) is not recommended for infants under 1 year old due to the potential risk of developing milk allergies. Unsalted popcorn (Choice B) can be a choking hazard for infants. Raw carrots (Choice D) are a potential choking hazard for a 9-month-old infant and may be difficult for them to chew and digest.
