Nursing Elites

1. .A nurse assesses a clients peripheral IV site, and notices edema and tenderness above the site. Which action should the nurse take next?

• A. Apply cold compresses to the IV site.
• B. Elevate the extremity on a pillow.
• C. Flush the catheter with normal saline.
• D. . Stop the infusion of intravenous fluids.

Correct answer: . Stop the infusion of intravenous fluids.

Rationale:

2. A newly graduated nurse is admitting a patient with a long history of emphysema. The new nurses preceptor is going over the patients past lab reports with the new nurse. The nurse takes note that the patients PaCO2 has been between 56 and 64 mm Hg for several months. The preceptor asks the new nurse why they will be cautious administering oxygen. What is the new nurses best response?

• A. The patients calcium will rise dramatically due to pituitary stimulation.
• B. Oxygen will increase the patients intracranial pressure and create confusion.
• C. Oxygen may cause the patient to hyperventilate and become acidotic.
• D. Using oxygen may result in the patient developing carbon dioxide narcosis and hypoxemia.

Correct answer: Using oxygen may result in the patient developing carbon dioxide narcosis and hypoxemia.

Rationale:

3. A patient with hypokalemia and heart failure is admitted to the telemetry unit. The nurse is aware that hypokalemia could cause which of the following abnormalities on an electrocardiogram (ECG)?

• A. Shortened P-R interval
• B. Inverted T wave
• C. Depressed U wave
• D. Elevated U wave

Correct answer: D

Rationale: The correct answer is D: Elevated U wave. Hypokalemia is associated with ECG changes such as an elevated U wave and flattened T waves. Choice A, a shortened P-R interval, is not typically seen in hypokalemia. Choice B, an inverted T wave, is more commonly associated with ischemia or CNS injury rather than hypokalemia. Choice C, a depressed U wave, is not a typical ECG abnormality seen in hypokalemia. Therefore, the correct ECG abnormality associated with hypokalemia is an elevated U wave.

4. The nurse is preparing to insert a peripheral IV catheter into a patient who will require fluids and IV antibiotics. How should the nurse always start the process of insertion?

• A. Leave one hand ungloved to assess the site.
• B. Cleanse the skin with normal saline.
• C. Ask the patient about allergies to latex or iodine.
• D. Remove excessive hair from the selected site.

Correct answer: Ask the patient about allergies to latex or iodine.

Rationale:

5. You are caring for a patient admitted with a diagnosis of acute kidney injury. When you review your patient's most recent laboratory reports, you note that the patient's magnesium levels are high. You should prioritize assessment for which of the following health problems?

• A. Diminished deep tendon reflexes
• B. Tachycardia
• C. Cool, clammy skin
• D. Acute flank pain

Correct answer: A

Rationale: Corrected Rationale: To assess a patient's magnesium status, the nurse should check deep tendon reflexes. Diminished deep tendon reflexes may indicate high serum magnesium levels, as hypermagnesemia can lead to neuromuscular effects. Tachycardia, cool clammy skin, and acute flank pain are not typically associated with high magnesium levels and are not priority assessments in this situation.
