Nursing Elites

1. A client receives a prescription for acetylcysteine (Mucomyst) 1.4 grams per nasogastric tube q4 hours. Acetylcysteine is available as a 10% solution (10 grams/100ml). How many ml of the 10% solution should the nurse administer per dose?

• A. 7
• B. 10
• C. 14
• D. 1.4 grams of acetylcysteine is equivalent to 14 ml of a 10% solution.

Correct answer: D

Rationale: To determine the amount of the 10% acetylcysteine solution to administer, convert the 1.4 grams to milligrams (1.4 grams = 1400 mg). Then, as the 10% solution contains 10 grams (10,000 mg) per 100 ml, it means there are 1000 mg of acetylcysteine in every 10 ml of the solution (10,000 mg / 100 ml = 100 mg/ml). Therefore, to administer 1400 mg (1.4 grams) of acetylcysteine, the nurse should give 14 ml of the 10% solution. Choices A, B, and C are incorrect as they do not accurately convert the amount of acetylcysteine to the corresponding volume of the 10% solution.

2. 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.

3. A woman with an anxiety disorder calls her obstetrician’s office and tells the nurse of increased anxiety since the normal vaginal delivery of her son three weeks ago. Since she is breastfeeding, she stopped taking her antianxiety medications, but thinks she may need to start taking them again because of her increased anxiety. What response is best for the nurse to provide this woman?

• A. Describe the safety of certain antianxiety medications during breastfeeding
• B. Encourage her to consider stress-relieving alternatives, such as deep breathing exercises
• C. Inform her that some antianxiety medications are safe to take while breastfeeding
• D. Explain that anxiety is a common response for the mother of a 3-week-old

Correct answer: C

Rationale: The correct answer is C. Some antianxiety medications are considered safe for use while breastfeeding, and the nurse should provide this information to alleviate the woman's concerns. Choice A has been corrected to focus on the safety of certain antianxiety medications during breastfeeding, which is more accurate. Choice B suggests stress-relieving alternatives, which may help but do not address the need for antianxiety medication if required. Choice D is incorrect because it minimizes the woman's concerns by dismissing her increased anxiety as a normal response.

4. To evaluate the medication’s effectiveness in a client with a respiratory tract infection, which laboratory values should the nurse monitor?

• A. White blood cell (WBC) count
• B. Sputum culture and sensitivity
• C. Droplet precautions
• D. Protective environment

Correct answer: A

Rationale: The correct answer is A: White blood cell (WBC) count. Monitoring the WBC count helps assess the overall response to infection and the effectiveness of the antibiotic. Sputum culture and sensitivity (choice B) are also important to confirm if the antibiotic is targeting the specific pathogen. Choices C and D, droplet precautions and protective environment, are not laboratory values but rather infection control measures that do not directly evaluate the medication's effectiveness in treating the infection.

5. 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.
