Nursing Elites

1. The client has received IV solutions for three (3) days through a 20-gauge IV catheter placed in the left cephalic vein. On morning rounds, the nurse notes the IV site is tender to palpation and a red streak has formed. Which action should the nurse implement first?

• A. Start a new IV in the right hand.
• B. Discontinue the intravenous line.
• C. Complete an incident record.
• D. Place a warm washcloth over the site.

Correct answer: B

Rationale: The first action should be to discontinue the intravenous line to prevent further complications such as infection or thrombophlebitis. Starting a new IV in the right hand is not the priority as addressing the current issue is important. Completing an incident record can be done after addressing the immediate concern of the IV site. Placing a warm washcloth over the site does not address the red streak and tenderness, which may indicate an infection that requires discontinuation of the IV line.

2. For a diabetic male client with a foot ulcer, the physician orders bed rest, a wet-to-dry dressing change every shift, and blood glucose monitoring before meals and bedtime. Why are wet-to-dry dressings used for this client?

• A. They contain exudate and provide a moist wound environment.
• B. They protect the wound from mechanical trauma and promote healing.
• C. They debride the wound and promote healing by secondary intention.
• D. They prevent the entrance of microorganisms and minimize wound discomfort.

Correct answer: C

Rationale: Wet-to-dry dressings are utilized in this case to debride the wound by removing dead tissue and promoting healing by secondary intention. Choice A is incorrect as wet-to-dry dressings do not provide a moist wound environment; instead, they promote drying to aid in debridement. Choice B is incorrect because their primary purpose is not to protect the wound but to remove dead tissue. Choice D is incorrect as the main function of wet-to-dry dressings is not to prevent the entrance of microorganisms or minimize wound discomfort.

3. Capillary glucose monitoring is being performed every 4 hours for a female client diagnosed with diabetic ketoacidosis. Insulin is administered using a scale of regular insulin according to glucose results. At 2 p.m., the client has a capillary glucose level of 250 mg/dl for which she receives 8 U of regular insulin. Nurse Vince should expect the dose's:

• A. Onset to be at 2 p.m. and its peak to be at 3 p.m.
• B. Onset to be at 2:15 p.m. and its peak to be at 3 p.m.
• C. Onset to be at 2:30 p.m. and its peak to be at 4 p.m.
• D. Onset to be at 4 p.m. and its peak to be at 6 p.m.

Correct answer: C

Rationale: The correct answer is C. Regular insulin typically has an onset of action within 30 minutes and peaks 2-4 hours after administration. Given that the insulin was administered at 2 p.m., the onset of action can be expected around 2:30 p.m., and the peak effect would occur between 4-6 p.m. Choice A is incorrect as the onset and peak are too close together for regular insulin. Choice B is incorrect because the onset time is too soon after administration. Choice D is incorrect as the onset time is too delayed for regular insulin.

4. A healthcare provider caring for a client with severe malnutrition reviews the laboratory results and notes a magnesium level of 1.0 mg/dL. Which electrocardiographic change would the healthcare provider expect to note based on the magnesium level?

• A. Prominent U waves
• B. Prolonged PR interval
• C. Depressed ST segment
• D. Widened QRS complexes

Correct answer: C

Rationale: A magnesium level of 1.0 mg/dL can cause a depressed ST segment on the ECG. Magnesium deficiency commonly leads to ST segment depression on an electrocardiogram. Prominent U waves are associated with hypokalemia, prolonged PR interval is seen in conditions like first-degree heart block, and widened QRS complexes are typically related to conditions affecting the conduction system of the heart, such as bundle branch blocks.

5. The nurse and an unlicensed nursing assistant are caring for a group of clients. Which nursing intervention should the nurse perform?

• A. Measure the client's output from the indwelling catheter.
• B. Record the client's intake and output on the I & O sheet.
• C. Instruct the client on appropriate fluid restrictions.
• D. Provide water for a client diagnosed with diabetes insipidus.

Correct answer: C

Rationale: Instructing the client on appropriate fluid restrictions is a nursing intervention that requires professional judgment and should be performed by the nurse. In this scenario, the nurse should provide education regarding fluid restrictions based on the client's individual needs. Measuring the client's output from the indwelling catheter (choice A) and recording intake and output (choice B) can be tasks delegated to the unlicensed nursing assistant. Providing water for a client diagnosed with diabetes insipidus (choice D) is not appropriate as these clients often require careful fluid management to prevent complications.
