Question 1 of 5
While caring for a client receiving Heparin therapy, which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?
Correct Answer: C
Rationale: The nurse should monitor the aPTT (activated partial thromboplastin time) when caring for a client receiving Heparin therapy. The aPTT reflects the intrinsic pathway of the clotting cascade and is used to monitor the effectiveness of heparin, which primarily affects this pathway by potentiating antithrombin III. Monitoring the aPTT helps ensure that the client's blood is within the therapeutic range to prevent thrombus formation.
Question 2 of 5
A healthcare professional is preparing to administer a dose of Hydromorphone IV to a client. Which of the following actions should the healthcare professional take?
Correct Answer: A
Rationale: The healthcare professional should administer IV Hydromorphone slowly over 5 minutes to reduce the risk of hypotension and respiratory depression. Rapid administration can lead to adverse effects, so it is crucial to administer the medication slowly to monitor the client's response and intervene promptly if needed.
Question 3 of 5
A client has a new prescription for Timolol eye drops. How should the client prevent systemic absorption of the medication according to the nurse's instructions?
Correct Answer: B
Rationale: When the client presses on the nasolacrimal duct while instilling eye drops, it temporarily blocks the lacrimal punctum. This obstruction helps prevent the systemic absorption of the medication by minimizing drainage into the nasolacrimal duct and subsequent systemic circulation. By following this technique, the client can enhance the localized effect of the eye drops and reduce the risk of systemic side effects.
Question 4 of 5
A healthcare provider is reviewing the health care record of a client who reports urinary incontinence and asks about a prescription for Oxybutynin. The provider should recognize that Oxybutynin is contraindicated in the presence of which of the following conditions?
Correct Answer: D
Rationale: Oxybutynin is an anticholinergic medication that can increase intraocular pressure. It is contraindicated in clients with glaucoma, as it can worsen the condition. Glaucoma is a condition characterized by increased intraocular pressure, and using Oxybutynin can further elevate this pressure, potentially leading to serious complications such as vision impairment or damage to the optic nerve.
Question 5 of 5
A client has a new prescription for Zolpidem. Which of the following instructions should the nurse include?
Correct Answer: A
Rationale: Zolpidem is classified as Pregnancy Risk Category C. It is important for the client to inform the provider if they plan to become pregnant because the medication may need to be adjusted or changed to ensure the safety of the fetus. This communication allows for appropriate monitoring and adjustments to be made to the treatment plan.
