Nursing Elites

1. A client with a history of congestive heart failure is prescribed digoxin (Lanoxin). Which assessment is most important for the nurse to obtain before administering this medication?

• A. Blood pressure
• B. Heart rate
• C. Respiratory rate
• D. Oxygen saturation

Correct answer: B

Rationale: The correct answer is B: Heart rate. Before administering digoxin to a client with a history of congestive heart failure, the nurse must assess the client's heart rate. Digoxin can cause bradycardia, so monitoring the heart rate is crucial to prevent potential complications. Assessing blood pressure, respiratory rate, and oxygen saturation are important assessments but are not as directly influenced by digoxin as heart rate is in this scenario. Blood pressure can be affected by various factors, including dehydration or other medications. Respiratory rate and oxygen saturation are more related to respiratory function and gas exchange, which are not the primary concerns when administering digoxin to a client with heart failure.

2. The nurse is changing the colostomy bag for a client who is complaining of leakage of diarrheal stool under the disposable ostomy bag. What action should the nurse implement to prevent leakage?

• A. Place a 4x4 wick in the stoma opening
• B. Apply a layer of zinc oxide ointment to the perimeter of the stoma
• C. Cut the bag opening to the measurement of the stoma size
• D. Administer a PRN antidiarrheal agent

Correct answer: C

Rationale: To prevent leakage of stool under the disposable ostomy bag, the nurse should cut the bag opening to the measurement of the stoma size. This action ensures a proper fit, which is crucial in preventing leaks that can lead to skin irritation and compromise stoma care. Placing a 4x4 wick in the stoma opening or applying zinc oxide ointment may not address the issue of leakage effectively. Administering a PRN antidiarrheal agent is not directly related to preventing leakage caused by an ill-fitting ostomy bag.

3. The nurse is assessing a client with an IV infusion of normal saline. The client reports pain and swelling at the IV site. What should the nurse do first?

• A. Slow the rate of infusion
• B. Apply a warm compress to the site
• C. Elevate the affected arm
• D. Discontinue the IV infusion

Correct answer: D

Rationale: The correct answer is to discontinue the IV infusion. Pain and swelling at the IV site may indicate infiltration or phlebitis, which requires immediate discontinuation of the infusion to prevent further complications. Continuing the infusion can lead to tissue damage or infection. Slowing the rate of infusion, applying a warm compress, or elevating the affected arm would not address the underlying issue of infiltration or phlebitis and could potentially worsen the condition by allowing more fluid to infiltrate the tissues.

4. Which client is at the highest risk for developing pressure ulcers?

• A. A 50-year-old client with a fractured femur
• B. A 30-year-old client with diabetes mellitus
• C. A 65-year-old client with limited mobility
• D. A 70-year-old client with a history of stroke

Correct answer: C

Rationale: Clients with limited mobility are at the highest risk for developing pressure ulcers due to prolonged pressure on specific areas of the body. This constant pressure can lead to tissue damage and ultimately result in pressure ulcers. While age and medical conditions such as diabetes and a history of stroke can contribute to the risk of pressure ulcers, limited mobility is the most significant factor as it directly affects the ability to shift positions and relieve pressure on vulnerable areas of the body. Therefore, the 65-year-old client with limited mobility is at the highest risk compared to the other clients. The 50-year-old client with a fractured femur may have limited mobility due to the injury, but it is temporary and may not be as prolonged as chronic limited mobility. The 30-year-old client with diabetes mellitus and the 70-year-old client with a history of stroke are at risk for developing pressure ulcers, but their conditions do not directly impact their ability to shift positions and alleviate pressure like limited mobility does.

5. The client with high blood pressure is being taught by the nurse to avoid adding salt during cooking. What effect does sodium have on blood pressure?

• A. It decreases the viscosity of blood
• B. It leads to increased fluid retention
• C. It causes vasoconstriction of the blood vessels
• D. It enhances the excretion of potassium

Correct answer: C

Rationale: The correct answer is C: 'It causes vasoconstriction of the blood vessels.' Sodium can lead to vasoconstriction, which narrows the blood vessels, increasing resistance to blood flow and subsequently raising blood pressure. Choices A, B, and D are incorrect. Sodium does not decrease blood viscosity, but it can lead to fluid retention, which increases blood volume and pressure. It does not enhance the excretion of potassium; instead, high sodium intake can lead to potassium excretion by the kidneys.
