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 is receiving intravenous potassium chloride for hypokalemia. Which action should the nurse take to prevent complications during the infusion?

• A. Administer the infusion rapidly
• B. Monitor the infusion site for signs of infiltration
• C. Use a syringe pump for the infusion
• D. Flush the IV line with normal saline before starting the infusion

Correct answer: B

Rationale: The correct action to prevent complications during the infusion of potassium chloride is to monitor the infusion site for signs of infiltration. Rapid administration can lead to adverse effects, including cardiac arrhythmias. Using a syringe pump is not typically necessary for this infusion. Flushing the IV line with normal saline is a good practice but not directly related to preventing complications specifically during the infusion of potassium chloride.

3. A client with diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. What do these symptoms indicate?

• A. Hypoglycemia
• B. Diabetic ketoacidosis (DKA)
• C. Hyperosmolar hyperglycemic state (HHS)
• D. Insulin shock

Correct answer: B

Rationale: Polyuria, polydipsia, and polyphagia are classic signs of diabetic ketoacidosis (DKA), which occurs due to a combination of hyperglycemia and ketone production. Hypoglycemia (Choice A) is characterized by low blood sugar levels, leading to symptoms like confusion, shakiness, and sweating, which are different from the symptoms described in the scenario. Hyperosmolar hyperglycemic state (HHS) (Choice C) typically presents with severe hyperglycemia, dehydration, and altered mental status, rather than the triad of symptoms mentioned. Insulin shock (Choice D) refers to a severe hypoglycemic reaction due to excessive insulin, manifesting with confusion, sweating, and rapid heartbeat, not the symptoms seen in the client with diabetes mellitus described in this scenario.

4. The nurse is caring for a client with a nasogastric tube. Which action should the nurse take to ensure proper functioning of the tube?

• A. Flush the tube with 50 mL of normal saline every 8 hours
• B. Clamp the tube when not in use
• C. Position the client in a supine position
• D. Verify tube placement by checking pH of gastric contents

Correct answer: D

Rationale: Verifying tube placement by checking the pH of gastric contents is crucial to ensure the nasogastric tube is correctly positioned in the stomach. This action helps prevent complications such as aspiration. Flushing the tube with normal saline every 8 hours is not necessary for ensuring proper functioning of the tube. Clamping the tube when not in use may lead to the build-up of gastric secretions and blockages. Positioning the client in a supine position is not directly related to ensuring the proper functioning of the nasogastric tube.

5. An older adult woman with a long history of COPD is admitted with progressive shortness of breath and a persistent cough, is anxious, and is complaining of dry mouth. Which intervention should the nurse implement?

• A. Administer a prescribed sedative
• B. Encourage client to drink water
• C. Apply a high flow venturi mask
• D. Assist her to an upright position

Correct answer: D

Rationale: Assisting the client to an upright position is the most appropriate intervention in this situation. Placing the client upright helps improve lung expansion by reducing diaphragmatic pressure, facilitating better air exchange, and increasing oxygenation. This position also aids in easing breathing efforts. Administering a sedative (Choice A) may further depress the respiratory system, worsening the breathing problem. Encouraging the client to drink water (Choice B) may not directly address the respiratory distress caused by COPD. Applying a high flow venturi mask (Choice C) may be beneficial in some cases but assisting the client to an upright position should be the priority to optimize respiratory function.
