Question 1 of 5.
A client newly diagnosed with Type I Diabetes Mellitus asks the purpose of the test measuring glycosylated hemoglobin. The nurse should explain that the purpose of this test is to determine:
A. The presence of anemia often associated with Diabetes
B. The oxygen carrying capacity of the client's red cells
C. The average blood glucose for the past 2-3 months
D. The client's risk for cardiac complications
Explanation: The average blood glucose for the past 2-3 months. By testing the portion of the hemoglobin that absorbs glucose, it is possible to determine the average blood glucose over the life span of the red cell, 120 days.
Question 2 of 5.
Which laboratory test should the nurse monitor for the client receiving the intravenous steroid Solu-Medrol?
A. Potassium level.
B. Sputum culture and sensitivity.
C. Glucose level.
D. Arterial blood gases.
Explanation: Solu-Medrol (methylprednisolone) can cause hyperglycemia, requiring glucose monitoring, especially IV. Potassium, sputum, or ABGs are less directly affected.
Question 3 of 5.
The nurse administers 18 units of Humulin N, an intermediate-acting insulin, at 1630. Which priority intervention should the nurse implement?
A. Monitor the client's hemoglobin A1c.
B. Make sure the client eats the evening meal.
C. Check the a.c. blood glucometer reading.
D. Ensure the client eats a snack.
Explanation: Humulin N peaks in 4-12 hours; evening meal prevents hypoglycemia during peak action. A1c, a.c. checks, or snacks are less immediate.
Question 4 of 5.
The nurse is administering a.m. medications. Which medication should the nurse administer first?
A. The daily digoxin to the client diagnosed with congestive heart failure.
B. The loop diuretic to the client with a serum potassium level of 3.1 mEq/L.
C. The mucosal barrier Carafate to the client diagnosed with peptic ulcer disease.
D. Solu-Medrol IVP to a client diagnosed with chronic lung disease.
Explanation: Carafate (sucralfate) forms a protective barrier and must be given on an empty stomach, 30-60 minutes before other meds, to be effective for PUD.
Question 5 of 5.
The client's vital signs are T 99.2°F, AP 59, R 20, and BP 108/72. Which medication would the nurse question administering?
A. Theo-Dur, a bronchodilator.
B. Inderal, a beta blocker.
C. Ampicillin, an antibiotic.
D. Cardizem, a calcium channel blocker.
Explanation: Inderal (propranolol) slows HR; an apical pulse of 59 warrants holding it, per guidelines, to avoid bradycardia. Other meds are unaffected by HR.
