1. A male client with diabetes mellitus takes Novolin 70/30 insulin before meals and azithromycin (Zithromax) PO daily, using medication he brought from home. When the nurse delivers his breakfast tray, the client tells the nurse that he took his insulin but forgot to take his daily dose of the Zithromax an hour before breakfast as instructed. What action should the nurse implement?

A. Offer to obtain a new breakfast tray in an hour so the client can take the Zithromax
B. Instruct the client to eat his breakfast and take the Zithromax two hours after eating
C. Tell the client to skip that day's dose and resume taking the Zithromax the next day
D. Provide a PRN dose of an antacid to take with the Zithromax right after breakfast

Correct answer: B

Rationale: To ensure the effectiveness of the antibiotic and manage blood glucose levels, the client should take the Zithromax two hours after eating. Option A is incorrect because obtaining a new breakfast tray is not necessary to administer the missed dose. Option C is incorrect as skipping a dose can lead to decreased effectiveness of the antibiotic. Option D is incorrect because providing an antacid is not indicated in this situation.

2. A healthcare provider is assessing a client who is receiving treatment for dehydration. Which assessment finding indicates that the client is responding to the treatment?

A. Dry mucous membranes
B. Increased urine output
C. Decreased skin turgor
D. Elevated heart rate

Correct answer: B

Rationale: Increased urine output is a positive sign indicating that the client is responding to the treatment for dehydration. It suggests that the client's kidneys are functioning better, helping to eliminate excess fluid and waste products from the body. Dry mucous membranes (Choice A) are a sign of dehydration, not improvement. Decreased skin turgor (Choice C) and elevated heart rate (Choice D) are also symptoms of dehydration and do not indicate a positive response to treatment.

3. The nurse is administering total parenteral nutrition (TPN) via a central line at 75 ml/hour to a client who had a bowel resection 4 days ago. Which laboratory finding requires the most immediate intervention by the nurse?

A. Blood glucose of 140 mg/dL
B. White blood cell count of 8000/mm³
C. Serum potassium of 3.8 mEq/L
D. Serum calcium of 7.8 mg/dL

Correct answer: D

Rationale: The correct answer is D. A serum calcium level of 7.8 mg/dL requires immediate intervention due to the risk of hypocalcemia. Hypocalcemia can lead to serious complications such as tetany, seizures, and cardiac arrhythmias. The other laboratory findings are within normal limits or slightly elevated, which do not pose an immediate threat to the client's health in this scenario.

4. A 2-year-old boy with short bowel syndrome has progressed to receiving enteral feedings only. Today his stools are occurring more frequently and have a more liquid consistency. His temperature is 102.2°F and he has vomited twice in the past four hours. Which assessment finding indicates that the child is becoming dehydrated?

A. Occult blood in the stool
B. Abdominal distention
C. Elevated urine specific gravity
D. Hyperactive bowel sounds

Correct answer: C

Rationale: Elevated urine specific gravity is a sign of dehydration in children. In the scenario provided, the child is experiencing increased stool frequency, liquid consistency, fever, and vomiting, indicating fluid loss and potential dehydration. Occult blood in the stool may suggest gastrointestinal bleeding but is not a direct indicator of dehydration. Abdominal distention can be seen in various conditions and is not specific to dehydration. Hyperactive bowel sounds are more commonly associated with increased bowel motility, not necessarily dehydration.

5. The nurse is planning care for a client receiving chemotherapy. Which intervention should the nurse include to manage the client's nausea?

A. Administer an antiemetic before meals
B. Provide frequent mouth care
C. Encourage small, frequent meals
D. Offer clear liquids

Correct answer: A

Rationale: Administering an antiemetic before meals is a crucial intervention to manage chemotherapy-induced nausea. Antiemetics help prevent or reduce nausea and vomiting associated with chemotherapy. Providing frequent mouth care (choice B) is important for managing oral mucositis but not specifically for nausea. Encouraging small, frequent meals (choice C) and offering clear liquids (choice D) are beneficial strategies for managing gastrointestinal side effects but may not be as effective in controlling nausea as administering antiemetics.
