Nursing Elites

1. During operation, who manages the lighting, noise, temperature and other factors in the operating room suite?

• A. Nurse Supervisor
• B. Surgeon
• C. Circulating Nurse
• D. Scrub Nurse

Correct answer: C

Rationale: In an operating room, the circulating nurse is responsible for managing environmental factors such as lighting, noise, and temperature. This role includes ensuring the comfort and safety of the patient, as well as the efficiency of the team. While the Nurse Supervisor, Surgeon, and Scrub Nurse also have crucial roles during an operation, they do not directly manage the environmental conditions of the operating room. The rationale provided does not directly address the question asked, and appears to relate more to the broader role of nursing in patient care.

2. Each statement is true of calcium within saliva, except one. Which is the exception?

• A. Saliva is supersaturated with calcium.
• B. Saliva is a source of calcium to mineralize an immature or demineralized enamel surface.
• C. Calcium and phosphate in saliva provide a buffering action.
• D. Calcium within saliva increases dental caries.

Correct answer: D

Rationale: The correct answer is D. Calcium within saliva does not increase dental caries; in fact, the buffering action provided by calcium and phosphate in saliva inhibits caries formation by preventing the dissolution of enamel by plaque biofilm. Choice A is correct as saliva is indeed supersaturated with calcium. Choice B is correct as saliva serves as a source of calcium to mineralize an immature or demineralized enamel surface. Choice C is correct as calcium and phosphate in saliva do provide a buffering action to protect teeth from acids.

3. A nurse is planning care for a toddler who has burns over 50% total body surface area. Which of the following actions should the nurse include in the plan of care?

• A. Administer enteral feedings
• B. Limit intake of vitamin C
• C. Limit dietary protein
• D. Administer insulin prior to meals

Correct answer: A

Rationale: Administering enteral feedings is crucial for ensuring adequate nutrition and supporting healing in toddlers with extensive burns. Burns over 50% total body surface area can lead to increased metabolic demands, making it essential to provide nutrition through enteral feedings to meet the child's needs for healing and recovery. Limiting intake of vitamin C or dietary protein would be detrimental in this scenario as the child requires increased amounts of nutrients to support healing. Administering insulin prior to meals is not indicated in this case as the priority is to provide adequate nutrition to promote healing.

4. A client receiving total parenteral nutrition (TPN) suddenly develops tremors, dizziness, and diaphoresis. The client said, 'I feel weak and the bag was empty.' Which is the most likely complication the client is currently experiencing?

• A. Fluid volume overload
• B. Sepsis
• C. Hyperglycemia
• D. Hypoglycemia

Correct answer: D

Rationale: The client experiencing tremors, dizziness, diaphoresis, weakness, and stating that the TPN bag is empty is likely experiencing hypoglycemia. Hypoglycemia can occur when the TPN infusion suddenly stops, leading to a rapid drop in blood sugar levels. Symptoms of hypoglycemia include tremors, dizziness, diaphoresis, and weakness. Choices A, B, and C are incorrect as the symptoms presented are more consistent with hypoglycemia rather than fluid volume overload, sepsis, or hyperglycemia.

5. Symptoms of irritable bowel syndrome are most likely associated with disturbed defecation, bloating, and _____.

• A. rectal bleeding
• B. abdominal pain
• C. rectal fissures
• D. esophageal paralysis

Correct answer: B

Rationale: Abdominal pain is a common symptom of irritable bowel syndrome (IBS), along with bloating and changes in bowel habits. Rectal bleeding (choice A) is more commonly associated with conditions like inflammatory bowel disease or colorectal cancer. Rectal fissures (choice C) may cause rectal bleeding but are not typically considered a core symptom of IBS. Esophageal paralysis (choice D) is unrelated to the symptoms of IBS, which primarily affect the lower gastrointestinal tract.
