Nursing Elites

1. Does the hypothalamus control the feeling of hunger and satiety, and are fats the best nutrient in creating the feeling of satiety?

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: Yes, the hypothalamus plays a crucial role in regulating hunger and satiety. Fats are indeed known to be highly satiating nutrients, helping to create a feeling of fullness and satisfaction after a meal. Therefore, both statements are true. Choice B is incorrect because fats are indeed effective in promoting satiety.

2. A client with anorexia undergoing radiation therapy is being taught by a nurse. Which instruction should the nurse include in the teaching?

• A. Limit high-calorie supplements to between meals
• B. Avoid overeating during your 'good' days
• C. Eat hot foods instead of cold foods
• D. Consume nutrient-dense foods first

Correct answer: D

Rationale: The correct instruction for a client with anorexia undergoing radiation therapy is to consume nutrient-dense foods first. This ensures that the client receives the necessary calories and nutrients. Option A is incorrect because high-calorie supplements should not be limited but rather incorporated wisely into the diet. Option B is incorrect as overeating is not recommended regardless of the type of day. Option C is incorrect as there is no specific preference for hot foods over cold foods in managing anorexia during radiation therapy.

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. Approximately 75% of reputable producers of bottled water use groundwater as their water source. Plain tap water is the most natural source of fluids.

• 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: A

Rationale: Both statements are true. Approximately 75% of reputable producers of bottled water use groundwater as their water source, which is the same source as the public water supply. Plain tap water, coming from underground sources or reservoirs, is indeed a natural source of fluids. The first statement is supported by the fact that groundwater is a common source for bottled water due to its purity and taste. The second statement is true as tap water is sourced from natural reservoirs or underground aquifers in most cases, making it a natural fluid source for consumption. Other choices are incorrect because both statements are factually accurate based on common practices in the production and sourcing of bottled water and tap water.

5. You are to measure the client's initial blood pressure reading by doing all of the following EXCEPT:

• A. Take the blood pressure reading on both arms for comparison
• B. Listen to and identify the phases of Korotkoff sounds
• C. Pump the cuff to around 50 mmHg above the point where the pulse is obliterated
• D. Observe procedures for infection control

Correct answer: B

Rationale: When measuring blood pressure, it is crucial to follow specific steps to obtain accurate readings. Taking the blood pressure on both arms for comparison helps assess any variations. Pumping the cuff to around 50 mmHg above the point of pulse obliteration ensures accurate measurements. Observing procedures for infection control is vital to prevent the spread of infections. Listening to and identifying the phases of Korotkoff sounds are associated with auscultatory blood pressure measurements, not the initial blood pressure reading process.
