Nokea
The nurse is planning to administer two medications at 0900. Which property of the drugs indicates a need to monitor the client for toxicity?
- A. Short half-life
- B. High therapeutic index
- C. Highly protein-bound
- D. Low bioavailability
Correct Answer: C
Rationale: The correct answer is C, 'Highly protein-bound.' Drugs that are highly protein-bound can displace from protein-binding sites, leading to increased free drug levels in the blood, which can result in toxicity. Monitoring the client for toxicity is crucial when administering highly protein-bound drugs. Choices A, B, and D are incorrect. A short half-life does not necessarily indicate a need for monitoring toxicity; a high therapeutic index indicates a wide safety margin between the effective dose and the toxic dose, reducing the risk of toxicity; low bioavailability refers to the fraction of the drug that reaches the systemic circulation unchanged and does not directly relate to the risk of toxicity.

A woman who is breastfeeding calls her obstetrician's office and reports increased anxiety since the vaginal delivery of her son three weeks ago. She stopped taking her antianxiety medications but is thinking of restarting them. What response should the nurse provide?
- A. Describe the potential transmission of drugs to the infant through breast milk.
- B. Encourage her to utilize stress-relieving alternatives, such as deep breathing.
- C. Explain that anxiety is a common reaction for mothers of 3-week-old infants.
- D. Inform her that some antianxiety medications are safe to take while breastfeeding.
Correct Answer: D
Rationale: The correct answer is D because some antianxiety medications are considered safe during breastfeeding. The nurse should reassure the client and encourage her to discuss options with her healthcare provider to manage anxiety safely while continuing to breastfeed. Choice A is incorrect because it focuses on the transmission of drugs rather than providing guidance on safe medication use. Choice B, while promoting stress-relieving techniques, does not address the potential need for medication. Choice C is incorrect as it minimizes the woman's reported anxiety, which may require professional intervention.
When assessing an IV site used for fluid replacement and medication administration, the client complains of tenderness when the arm is touched above the site. Which additional assessment finding warrants immediate intervention by the nurse?
- A. Cool skin at the IV insertion site
- B. Presence of fluid leaking around the IV catheter
- C. Swelling above the IV site
- D. Red streaks tracking the vein
Correct Answer: D
Rationale: The correct answer is D: "Red streaks tracking the vein." Red streaks indicate phlebitis, an inflammation of the vein that can lead to serious complications like infection or thrombophlebitis. Immediate intervention is required to prevent further damage. Choice A, cool skin at the IV insertion site, could indicate decreased circulation but is not as urgent as addressing phlebitis. Choice B, presence of fluid leaking around the IV catheter, may indicate infiltration or dislodgement of the catheter, requiring intervention but not as urgently as phlebitis. Choice C, swelling above the IV site, may suggest localized inflammation but doesn't pose an immediate threat like phlebitis does.
Which of the following statements reflects appropriate teaching to prevent injury in a client with rheumatoid arthritis?
- A. Use heat applications to relieve swelling and stiffness.
- B. Take warm showers before activity.
- C. Use cold packs to relieve joint pain.
- D. Take prescribed anti-inflammatory medications with meals.
Correct Answer: C
Rationale: The correct answer is C. Using cold packs to relieve joint pain is appropriate for clients with rheumatoid arthritis as cold therapy is more effective at reducing inflammation and pain in these conditions. Heat applications may exacerbate the symptoms by increasing swelling. Taking warm showers before activity may provide comfort but does not directly address joint pain or prevent injury. While anti-inflammatory medications are commonly prescribed, they are not directly related to preventing injury in clients with rheumatoid arthritis.
An unlicensed assistive personnel (UAP), who usually works on a surgical unit, is assigned to float to a pediatric unit. Which question by the charge nurse would be most appropriate when making delegation decisions?
- A. How long have you been a UAP and what units have you worked on?
- B. What type of care do you provide on the surgical unit, and what are the ages of the clients?
- C. What is your comfort level in caring for children and at what ages?
- D. Have you reviewed the list of expected skills you might need on this unit?
Correct Answer: D
Rationale: The most appropriate question by the charge nurse would be to ask the UAP if they have reviewed the list of expected skills needed on the pediatric unit. This ensures that the UAP is aware of the specific skills required for safe and appropriate care in that particular unit. Choices A, B, and C do not directly address the need for the UAP to review the expected skills, which is crucial for delegation decisions during floating assignments.
The nurse is assessing a client with a history of schizophrenia who reports feeling sedated after starting a new antipsychotic medication. Which intervention is most appropriate?
- A. Reassure the client that sedation will subside with continued use
- B. Instruct the client to take the medication at bedtime
- C. Teach the client to take the medication with food
- D. Consult the healthcare provider to reduce the dosage
Correct Answer: B
Rationale: Instructing the client to take the medication at bedtime is the most appropriate intervention. Taking antipsychotic medications at bedtime can help reduce the impact of sedation on the client's daily activities. This approach allows the client to sleep through the sedative effects. Choice A is incorrect because just reassuring the client may not address the immediate issue of sedation. Choice C is incorrect as taking the medication with food does not directly address the sedation concern. Choice D is not the first-line intervention; adjusting the dosage should be done by the healthcare provider after assessing the client's response to the medication.
