Nursing Elites

1. The healthcare professional is administering an intermittent infusion of an antibiotic to a client with an antecubital saline lock. After opening the roller clamp on the IV tubing, the alarm on the infusion pump indicates an obstruction. What action should be taken first?

• A. Check for a blood return.
• B. Reposition the client's arm.
• C. Remove the IV site dressing.
• D. Flush the lock with saline.

Correct answer: B

Rationale: Repositioning the client's arm is the initial action to take when encountering an obstruction with an antecubital saline lock. Repositioning may correct any bending at the elbow that could be causing the obstruction, allowing for smoother infusion flow. Checking for a blood return, removing the IV site dressing, or flushing the lock with saline would be subsequent actions once the obstruction is addressed. Checking for a blood return is done to confirm proper placement, removing the IV site dressing is necessary for site assessment, and flushing the lock with saline helps maintain patency but should not be the first action when an obstruction is detected.

2. A client with a diagnosis of hyperkalemia is receiving sodium polystyrene sulfonate (Kayexalate). Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?

• A. Serum sodium level.
• B. Serum potassium level.
• C. Serum calcium level.
• D. Serum glucose level.

Correct answer: B

Rationale: The correct answer is B: Serum potassium level. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Monitoring the serum potassium level allows the nurse to assess the effectiveness of this medication in lowering the elevated potassium levels. Serum sodium (A), calcium (C), and glucose (D) levels are not directly impacted by the action of sodium polystyrene sulfonate.

3. The health care provider has changed a client's prescription from the PO to the IV route of administration. The nurse should anticipate which change in the pharmacokinetic properties of the medication?

• A. The client will experience increased tolerance to the drug's effects and may need a higher dose.
• B. The onset of action of the drug will occur more rapidly, resulting in a more rapid effect.
• C. The medication will be more highly protein-bound, increasing the duration of action.
• D. The therapeutic index will be increased, placing the client at greater risk for toxicity.

Correct answer: B

Rationale: When a medication is administered via the IV route, the absorptive process is bypassed, leading to a more rapid onset of action. This results in a faster effect of the drug. Choice A is incorrect because changing the route of administration does not necessarily lead to increased tolerance or the need for a higher dose. Choice C is incorrect as changing the route of administration does not directly affect the protein binding of a medication. Choice D is incorrect because increasing the therapeutic index would actually reduce the risk of toxicity, not increase it.

4. When faced with caring for a close friend in a professional setting, which action should the staff member take first?

• A. Notify the friend that all medical information will be kept confidential.
• B. Explain the relationship to the charge nurse and ask for reassignment.
• C. Approach the client and ask if the assignment is uncomfortable.
• D. Accept the assignment but protect the client's confidentiality.

Correct answer: B

Rationale: When faced with caring for a close friend in a professional setting, the staff member should first explain the relationship to the charge nurse and ask for reassignment. This is important to maintain professional boundaries, prevent conflicts of interest, and ensure that the care provided is unbiased and without compromising the friend's confidentiality. Choice A is incorrect because the priority should be on professional boundaries rather than informing the friend about confidentiality. Choice C is not appropriate as it puts the burden on the client to address any discomfort. Choice D is incorrect as accepting the assignment without addressing the potential conflict of interest could lead to compromised care.

5. A client with a history of diabetes mellitus is admitted with a blood glucose level of 600 mg/dL. What type of insulin should the nurse prepare to administer to this client?

• A. Regular insulin
• B. NPH insulin
• C. Lispro insulin
• D. Glargine insulin

Correct answer: A

Rationale: In a client with a blood glucose level of 600 mg/dL, which indicates severe hyperglycemia or diabetic ketoacidosis, the nurse should prepare to administer regular insulin (A). Regular insulin has a rapid onset of action and is the preferred choice for immediate correction of high blood glucose levels. NPH insulin (B), lispro insulin (C), and glargine insulin (D) are not suitable for the rapid correction of severe hyperglycemia.
