Nursing Elites

1. A nurse evaluates the following arterial blood gas values in a client: pH 7.48, PaO2 98 mm Hg, PaCO2 28 mm Hg, and HCO3 22 mEq/L. Which client condition should the nurse correlate with these results?

• A. Diarrhea and vomiting for 36 hours
• B. . Anxiety-induced hyperventilation
• C. Chronic obstructive pulmonary disease (COPD)
• D. Diabetic ketoacidosis and emphysema

Correct answer: B

Rationale:

2. Which mineral is important in hemoglobin production?

• A. Sodium
• B. Iodine
• C. Iron
• D. Chloride

Correct answer: C

Rationale: Iron (Fe) is a critical mineral in hemoglobin production. Hemoglobin is a protein found in red blood cells that is essential for transporting oxygen throughout the body. Sodium (Choice A), Iodine (Choice B), and Chloride (Choice D) are not directly involved in hemoglobin production. Sodium is an electrolyte that helps maintain fluid balance, Iodine is essential for thyroid hormone production, and Chloride is an electrolyte that helps regulate fluid balance and acidity in the body.

3. A nurse is caring for a client who is having a subclavian central venous catheter inserted. The client begins to report chest pain and difficulty breathing. After administering oxygen, which action should the nurse take next?

• A. Administer a sublingual nitroglycerin tablet
• B. Prepare to assist with chest tube insertion.
• C. . Place a sterile dressing over the IV site
• D. Re-position the client into the Trendelenburg position.

Correct answer: B

Rationale:

4. The nurse who assesses the patient's peripheral IV site and notes edema around the insertion site will document which complication related to IV therapy?

• A. Air emboli
• B. Phlebitis
• C. Infiltration
• D. Fluid overload

Correct answer: C

Rationale: Infiltration is the administration of non-vesicant solution or medication into the surrounding tissue. This can occur when the IV cannula dislodges or perforates the vein's wall. Infiltration is characterized by edema around the insertion site, leakage of IV fluid from the insertion site, discomfort, and coolness in the area of infiltration, and a significant decrease in the flow rate. Air emboli (Choice A) involves air entering the bloodstream. Phlebitis (Choice B) is inflammation of a vein. Fluid overload (Choice D) is an excessive volume of fluid in the circulatory system.

5. The community health nurse is performing a home visit to an 84-year-old woman recovering from hip surgery. The nurse notes that the woman seems uncharacteristically confused and has dry mucous membranes. When asked about her fluid intake, the patient states, I stop drinking water early in the day because it is just too difficult to get up during the night to go to the bathroom. What would be the nurses best response?

• A. I will need to have your medications adjusted so you will need to be readmitted to the hospital for a complete workup
• B. Limiting your fluids can create imbalances in your body that can result in confusion. Maybe we need to adjust the timing of your fluids.
• C. It is normal to be a little confused following surgery, and it is safe not to urinate at night.
• D. If you build up too much urine in your bladder, it can cause you to get confused, especially when your body is under stress.

Correct answer: B
