Nursing Elites

1. A 13-year-old girl, diagnosed with diabetes mellitus Type 1 at the age of 9, is admitted to the hospital in diabetic ketoacidosis. Which occurrence is the most likely cause of the ketoacidosis?

• A. Ate an extra peanut butter sandwich before gym class
• B. Incorrectly drew up and administered too much insulin
• C. Was not hungry, so she skipped eating lunch
• D. Has had a cold and ear infection for the past two days

Correct answer: B

Rationale: The correct answer is B. Incorrect insulin administration is a common cause of diabetic ketoacidosis. Administering too much insulin can lead to uncontrolled hyperglycemia, where the body starts breaking down fat for energy, resulting in the production of ketones. Choices A, C, and D are less likely to directly cause diabetic ketoacidosis. Eating an extra peanut butter sandwich, skipping lunch, or having a cold and ear infection would not directly lead to the metabolic derangements seen in diabetic ketoacidosis.

2. The client with diabetes mellitus type 1 has a fruity breath odor. What is the priority nursing action?

• A. Evaluate the client’s intake and output
• B. Measure the client’s capillary blood glucose
• C. Consult with the dietitian about the client’s diet
• D. Apply a pulse oximeter to the client’s finger

Correct answer: B

Rationale: Fruity breath odor in a client with diabetes mellitus type 1 can indicate ketoacidosis, a serious complication. Measuring the client’s capillary blood glucose is the priority nursing action in this scenario as it helps diagnose and manage the condition effectively. Evaluating intake and output may be important for overall assessment but not the priority when dealing with a potential emergency like ketoacidosis. Consulting with a dietitian about the client’s diet is important for long-term management but not the immediate priority. Applying a pulse oximeter is not relevant to addressing the fruity breath odor and suspected ketoacidosis.

3. While changing a client’s chest tube dressing, the nurse notes a crackling sensation when gentle pressure is applied to the skin at the insertion site. What is the best action for the nurse to take?

• A. Apply a pressure dressing around the chest tube insertion site
• B. Assess the client for allergies to topical cleaning agents
• C. Measure the area of swelling and crackling
• D. Administer an oral antihistamine per PRN protocol

Correct answer: A

Rationale: A crackling sensation indicates subcutaneous emphysema, caused by air trapped under the skin. Applying a pressure dressing around the chest tube insertion site can help manage the issue by preventing further air leakage into the tissues. Choice B is incorrect because the crackling sensation is not related to allergies. Choice C is incorrect as measuring the area does not address the underlying cause. Choice D is incorrect as administering an oral antihistamine is not indicated for subcutaneous emphysema.

4. In what order should the nurse perform the steps of a surgical hand scrub prior to entering the operating room?

• A. Rinse from the fingertips to the elbow
• B. Scrape under the nails with a nail pick
• C. Use a soapy brush to scrub the hands
• D. Cleanse the arm with a lathered brush

Correct answer: B

Rationale: The correct order for performing a surgical hand scrub is to first scrape under the nails with a nail pick, then scrub the hands using a soapy brush, cleanse the arms, and finally rinse. This sequence ensures thorough cleaning and minimizes the risk of contamination. Choice A is incorrect because rinsing should be the final step, not the first. Choice C is incorrect as scrubbing the hands comes after scraping under the nails. Choice D is incorrect as cleansing the arms should follow hand scrubbing, not precede it.

5. The nurse is assessing an infant with pyloric stenosis. Which pathophysiological mechanism is the most likely consequence of this infant’s clinical picture?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory alkalosis
• D. Respiratory acidosis

Correct answer: B

Rationale: Pyloric stenosis often leads to metabolic alkalosis due to the loss of gastric acid from vomiting. Metabolic acidosis would not be expected in pyloric stenosis as there is no excessive acid accumulation. Respiratory alkalosis and respiratory acidosis are not typically associated with pyloric stenosis, making them incorrect choices.
