Nursing Elites

1. What physiologic role does calcium 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: A

Rationale: The correct answer is A: 'Blood clotting, transmission of nerve impulses, muscle contraction and relaxation.' Calcium plays a crucial role in various physiological functions such as blood clotting, transmission of nerve impulses, muscle contraction and relaxation, membrane permeability, and activation of certain enzymes. Choice B is incorrect because while calcium is involved in calcium homeostasis, it is not the only role it plays in the body. Choice C is incorrect as calcium indeed has several known metabolic functions, and it is not solely for preventing caries. Choice D is also incorrect as the functions mentioned are primarily carried out by other nutrients and not specifically by calcium.

2. A healthcare provider is evaluating a client who reports paresthesia of the hands and feet. The provider should identify this manifestation as an indication of which of the following dietary deficiencies?

• A. Iron
• B. Riboflavin
• C. Vitamin C
• D. Vitamin B12

Correct answer: D

Rationale: Correct! Vitamin B12 deficiency can lead to neurological symptoms, including paresthesia (tingling or numbness) of the hands and feet, due to its role in nerve health. Iron deficiency is more commonly associated with anemia symptoms like fatigue and pallor. Riboflavin deficiency can cause mouth and skin changes. Vitamin C deficiency is linked to scurvy symptoms like bleeding gums and easy bruising.

3. Which outcome has been shown to be most closely associated with breastfeeding infants of mothers who smoke?

• A. poor temperature regulation
• B. vision impairment
• C. vomiting
• D. elevated blood pressure

Correct answer: C

Rationale: The correct answer is C: vomiting. Infants breastfed by mothers who smoke are more likely to experience vomiting and gastrointestinal issues due to the transfer of nicotine and other harmful substances through breast milk. Choices A, B, and D are incorrect. Poor temperature regulation, vision impairment, and elevated blood pressure are not the primary outcomes closely associated with breastfeeding infants of mothers who smoke.

4. A nurse is planning care for a client who has ascites secondary to liver disease. Which of the following interventions should the nurse include in the plan of care?

• A. Reduce complex carbohydrates to 30% of total calories.
• B. Restrict protein intake to less than 0.8 g/kg/day.
• C. Decrease daily caloric intake by 20%.
• D. Limit sodium to 2000 mg or less per day.

Correct answer: D

Rationale: The correct answer is to limit sodium to 2000 mg or less per day. Ascites, which is the abnormal accumulation of fluid in the abdominal cavity, is commonly associated with liver disease. Limiting sodium intake helps manage fluid retention by reducing the fluid accumulation in the abdomen. Choices A, B, and C are incorrect because reducing complex carbohydrates, restricting protein intake, or decreasing caloric intake are not the primary interventions for managing ascites in liver disease.

5. Surgery schedules are communicated to the OR usually a day prior to the procedure by the nurse of the floor or ward where the patient is confined. For orthopedic cases, what department is usually informed to be present in the OR?

• A. Rehabilitation department
• B. Laboratory department
• C. Maintenance department
• D. Radiology department

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.
