Nursing Elites

1. A healthcare professional prepares to administer sodium polystyrene sulfonate (Kayexalate) to a client. Before administering the medication, the professional reviews the action of the medication and understands that it:

• A. Releases bicarbonate in exchange for primarily sodium ions
• B. Releases sodium ions in exchange for primarily potassium ions
• C. Releases potassium ions in exchange for primarily sodium ions
• D. Releases sodium ions in exchange for primarily bicarbonate ions

Correct answer: B

Rationale: Sodium polystyrene sulfonate, such as Kayexalate, is a cation exchange resin that functions by releasing sodium ions in exchange for primarily potassium ions. This medication is commonly used to treat hyperkalemia, a condition characterized by elevated levels of potassium in the blood.

2. A health care provider (HCP) writes a prescription for digoxin (Lanoxin), 0.25 mg daily. The nurse teaches the client about the medication and tells the client that it is important to:

• A. Count the radial and carotid pulses every morning.
• B. Check the blood pressure every morning and evening.
• C. Stop taking the medication if the pulse is higher than 100 beats per minute.
• D. Withhold the medication and call the HCP if the pulse is less than 60 beats per minute.

Correct answer: D

Rationale: When taking digoxin, monitoring the pulse rate is essential due to its potential effects on heart rate. Digoxin can lead to bradycardia, where the pulse rate drops significantly. Withholding the medication and promptly contacting the healthcare provider if the pulse falls below 60 beats per minute is crucial to prevent severe complications and ensure appropriate management. Choices A, B, and C are incorrect because counting radial and carotid pulses, checking blood pressure, or stopping the medication based on a pulse rate higher than 100 beats per minute are not the primary monitoring parameters for a client taking digoxin.

3. A client with diabetes mellitus is prescribed Humulin NPH insulin. The client asks the nurse how to store unopened vials of insulin. The nurse instructs the client to:

• A. Freeze the insulin.
• B. Refrigerate the insulin.
• C. Store the insulin in a dark, dry place.
• D. Keep the insulin at room temperature.

Correct answer: B

Rationale: Unopened vials of insulin should be stored in the refrigerator until needed. Freezing insulin can damage it, affecting its efficacy. Storing insulin in a dark, dry place or at room temperature is not recommended as it can lead to degradation of the insulin. Refrigeration helps maintain the stability and effectiveness of insulin.

4. The client with breast cancer is receiving cyclophosphamide (Neosar). The nurse is reinforcing medication instructions and advises the client to:

• A. Take the medication with food.
• B. Increase fluid intake to 2000 to 3000 mL daily.
• C. Decrease sodium intake while taking the medication.
• D. Increase potassium intake while taking the medication.

Correct answer: B

Rationale: The correct answer is to increase fluid intake to 2000 to 3000 mL daily. Cyclophosphamide can cause hemorrhagic cystitis as a toxic effect. By increasing fluid intake, the client can help prevent this complication by promoting frequent urination, which reduces the concentration of the drug and its metabolites in the bladder. This dilution effect can help reduce the risk of bladder toxicity.

5. A healthcare professional is preparing to administer an intramuscular dose of penicillin to a client with a history of anaphylactic reactions to penicillin. Which action should the healthcare professional take first?

• A. Check the medication order for accuracy.
• B. Have an epinephrine injection available.
• C. Administer a test dose to check for a reaction.
• D. Ask the client about any allergies.

Correct answer: B

Rationale: When dealing with a client who has a history of anaphylactic reactions to penicillin, the priority action for the healthcare professional is to have an epinephrine injection readily available in case of a severe allergic reaction. In such cases, the immediate focus is on being prepared to manage a potentially life-threatening situation. While checking the medication order for accuracy, administering a test dose, and asking the client about allergies are essential steps in medication administration, the first priority is ensuring the availability of epinephrine to address a severe allergic reaction promptly.
