Nursing Elites

1. What is a causative factor of Hirschsprung disease?

• A. Frequent evacuation of solids, liquid, and gases
• B. Excessive peristaltic movement
• C. The absence of parasympathetic ganglion cells in a portion of the colon
• D. One portion of the bowel telescoping into another

Correct answer: C

Rationale: The correct answer is C: The absence of parasympathetic ganglion cells in a portion of the colon is a causative factor of Hirschsprung disease. This absence leads to the inability of the affected segment of the colon to relax, causing a functional obstruction. Choices A, B, and D are incorrect. Frequent evacuation of solids, liquid, and gases, excessive peristaltic movement, and one portion of the bowel telescoping into another are not causative factors of Hirschsprung disease.

2. A client with hyperkalemia is being treated in the emergency department. Which medication should the nurse prepare to administer?

• A. Potassium chloride
• B. Calcium gluconate
• C. Magnesium sulfate
• D. Sodium bicarbonate

Correct answer: B

Rationale: The correct answer is B, Calcium gluconate. In hyperkalemia, where potassium levels are elevated, calcium gluconate is administered to stabilize the myocardial cell membrane and protect the heart from potential arrhythmias. Potassium chloride (choice A) would worsen the condition by further increasing potassium levels. Magnesium sulfate (choice C) is not the primary treatment for hyperkalemia. Sodium bicarbonate (choice D) is used in metabolic acidosis, not specifically for hyperkalemia.

3. After hospitalization for SIADH, a client develops pontine myelinolysis. Which intervention should the nurse implement first?

• A. Reorient the client to the room
• B. Place an eye patch on one eye
• C. Evaluate the client's ability to swallow
• D. Perform range of motion exercises

Correct answer: C

Rationale: Evaluating the client's ability to swallow is the priority intervention in this scenario. Pontine myelinolysis can affect neurological functions, including swallowing ability, putting the client at risk for aspiration. Assessing the client's ability to swallow will help prevent complications such as aspiration pneumonia. Reorienting the client to the room, placing an eye patch, or performing range of motion exercises are not as critical as ensuring the client can safely swallow.

4. A client who has a history of unstable angina is admitted to the emergency department with chest pain.

• A. Chest pain relieved by rest.
• B. Chest pain unrelieved after taking 3 sequential nitroglycerin tablets.
• C. Chest pain occurring only with exertion.
• D. Chest pain lasting less than 5 minutes.

Correct answer: B

Rationale: Chest pain unrelieved after taking 3 sequential nitroglycerin tablets indicates a possible myocardial infarction and requires immediate medical attention.

5. Parents of a school-age child ask the nurse for suggestions in helping the child who is demonstrating school avoidance. What is an appropriate suggestion by the nurse?

• A. Take the child to the healthcare provider for testing.
• B. Be firm and insist the child go to school.
• C. Allow the child to stay home and rest.
• D. Consult with the teacher at school.

Correct answer: B

Rationale: When a child is demonstrating school avoidance, it is important for parents to be firm and insist that the child go to school. This helps establish a routine and prevents the behavior from becoming a pattern. Taking the child to the healthcare provider for testing (Choice A) may not be necessary at this stage as school avoidance is a behavioral issue. Allowing the child to stay home and rest (Choice C) may reinforce the avoidance behavior. While consulting with the teacher at school (Choice D) is important, the immediate focus should be on addressing the avoidance behavior at home.
