Nursing Elites

1. What physiological role does phosphorus play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction, and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: D

Rationale: The correct answer is D. Phosphorus plays a crucial role in ATP energy release, the metabolism of fats, carbohydrates, and proteins, and regulation of acid-base balance. Choices A, B, and C are incorrect. Phosphorus is not directly involved in blood clotting, transmission of nerve impulses, muscle contraction, or calcium homeostasis. It also has known metabolic functions and is not associated with caries prevention.

2. Children with cerebral palsy, Down syndrome, and intellectual disabilities are likely to have abnormal sensory input and muscle tone. A small, underdeveloped tongue is common in many such disorders and results in diminished nutritional status.

• 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, but the second is false. These children often have a large tongue or tongue thrust, which can interfere with feeding and nutrition.

3. 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.

4. A nurse is caring for a client with a major burn injury and is receiving TPN. Which of the following lab tests is the priority for the nurse to use to confirm the client is receiving adequate nutrition?

• A. Iron
• B. Magnesium
• C. Folic acid
• D. Prealbumin

Correct answer: D

Rationale: Prealbumin is a sensitive indicator of protein status and nutrition, making it a priority for assessing nutritional adequacy in clients receiving TPN. Iron, magnesium, and folic acid levels are important for overall health but do not specifically indicate nutritional adequacy in the context of TPN administration.

5. A nurse is planning care for a client who reports increasing difficulty swallowing food. Which of the following interventions should the nurse plan to take?

• A. Turn on the client’s television during meals.
• B. Place the client into a semi-reclining position for meals.
• C. Encourage the client to rest prior to mealtimes.
• D. Encourage the client to use a straw when drinking liquids.

Correct answer: C

Rationale: The correct answer is to encourage the client to rest prior to mealtimes. This intervention can help reduce fatigue and improve the ability to swallow. Turning on the client’s television during meals (choice A) may distract the client but does not directly address the swallowing issue. Placing the client into a semi-reclining position for meals (choice B) can help with swallowing difficulties, but resting before meals is more beneficial. Encouraging the client to use a straw when drinking liquids (choice D) is not the priority intervention for swallowing difficulties in this scenario.
