Nursing Elites

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 9-year-old boy with tetralogy of Fallot is being discharged following a cardiac catheterization. Which discharge instruction should the nurse provide the parents?

• A. Do not allow the child to return to school for at least one month
• B. Notify the healthcare provider if there is any drainage at the catheterization site
• C. Monitor the child's temperature and report any elevation
• D. Observe for any changes in the child's color or energy level

Correct answer: B

Rationale: The correct answer is to notify the healthcare provider if there is any drainage at the catheterization site. Drainage at the site can be a sign of infection, which needs prompt evaluation and treatment. Choices A, C, and D are not as crucial as identifying and reporting any drainage, which is more directly related to potential complications post-cardiac catheterization.

3. A client with type 2 diabetes mellitus is admitted for antibiotic treatment of a leg ulcer. Which signs and symptoms, indicative of hyperosmolar hyperglycemic nonketotic syndrome (HHNS), should the nurse report to the healthcare provider? (Select one that doesn't apply.)

• A. Increased heart rate
• B. Visual disturbances
• C. Presence of uremic frost
• D. Decreased mentation

Correct answer: C

Rationale: The correct answer is C, 'Presence of uremic frost.' Increased heart rate, visual disturbances, and decreased mentation are all signs and symptoms indicative of hyperosmolar hyperglycemic nonketotic syndrome (HHNS). Uremic frost, however, is not associated with HHNS but is a clinical finding seen in severe cases of chronic kidney disease. Therefore, the nurse should report the presence of uremic frost to the healthcare provider as a separate concern from HHNS.

4. 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.

5. The nurse is caring for a client who is receiving a continuous intravenous infusion of heparin. Which laboratory value should the nurse monitor to evaluate the effectiveness of the therapy?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Partial thromboplastin time (PTT)
• D. Hemoglobin level

Correct answer: C

Rationale: The correct answer is C. Partial thromboplastin time (PTT) is the laboratory value that should be monitored to evaluate the effectiveness of heparin therapy. PTT reflects the intrinsic pathway of coagulation and is specifically sensitive to heparin's anticoagulant effects. Monitoring the PTT helps ensure that the client is within the therapeutic range to prevent clot formation without increasing the risk of bleeding. Choices A, B, and D are incorrect because while they are important laboratory values in other contexts, they are not specifically used to monitor the effectiveness of heparin therapy.
