1. A patient is prescribed warfarin therapy for an artificial heart valve. Which of the following laboratory values should the nurse monitor for a therapeutic effect of warfarin?
- A. Hemoglobin
- B. Prothrombin time (PT)
- C. Bleeding time
- D. Activated partial thromboplastin time (aPTT)
Correct answer: B
Rationale: The correct answer is to monitor Prothrombin time (PT) when a patient is on warfarin therapy. Warfarin affects blood clotting, and PT is used to assess the therapeutic effect of this medication. Hemoglobin (Choice A) is not directly affected by warfarin therapy and does not reflect its therapeutic effect. Bleeding time (Choice C) measures the time it takes for bleeding to stop after a standardized cut and is not specific to warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice D) is more commonly used to monitor heparin therapy, not warfarin.
2. What symptoms should a patient taking Omeprazole report to the healthcare provider?
- A. Black, tarry stools
- B. Diarrhea
- C. Abdominal pain
- D. All of the above
Correct answer: D
Rationale: Patients taking Omeprazole should report black, tarry stools, diarrhea, or abdominal pain to the healthcare provider because these symptoms could indicate serious side effects associated with the medication. Black, tarry stools may suggest gastrointestinal bleeding, diarrhea can be a sign of a gastrointestinal infection or adverse drug reaction, and abdominal pain may indicate underlying issues that need attention. Choosing 'All of the above' is the correct answer as all these symptoms are important to report for proper evaluation and management.
3. A provider prescribes phenobarbital for a client who has a seizure disorder. The medication has a long half-life of 4 days. How many times per day should the nurse expect to administer this medication?
- A. One
- B. Two
- C. Three
- D. Four
Correct answer: A
Rationale: Phenobarbital has a long half-life of 4 days, meaning it remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should expect to administer phenobarbital once a day to maintain therapeutic levels and effectiveness. Administering it more than once a day would lead to unnecessary dosing and potential adverse effects as the medication remains active in the body for an extended period.
4. A child with Cystic Fibrosis has a new prescription for Acetylcysteine. Which of the following information should the nurse include in the instructions?
- A. Expect this medication to suppress your cough.
- B. Expect this medication to smell like rotten eggs.
- C. Expect this medication to cause euphoria.
- D. Expect this medication to turn your urine orange.
Correct answer: B
Rationale: The correct answer is B: 'Expect this medication to smell like rotten eggs.' Acetylcysteine contains sulfur, which gives it a characteristic rotten-egg odor. This smell is normal and expected when using this medication. Choices A, C, and D are incorrect. Acetylcysteine is not used to suppress cough, cause euphoria, or turn urine orange.
5. A client has a prescription for a Nitroglycerin transdermal patch. Which of the following instructions should be included by the healthcare provider?
- A. Apply the patch to a hairless area of the body.
- B. Remove the patch every 12 hours.
- C. Massage the patch after applying it.
- D. Place the patch over a hairless area of the body.
Correct answer: D
Rationale: The correct instruction for a Nitroglycerin transdermal patch is to place it over a hairless area of the body. This is essential to ensure proper adhesion and consistent absorption of the medication. Hair can impede the patch's ability to stick to the skin and deliver the medication effectively. Therefore, choices A, B, and C are incorrect. Applying the patch to the same site every day (Choice A) may lead to skin irritation, removing the patch every 12 hours (Choice B) is not typically recommended for Nitroglycerin patches, and massaging the patch after applying it (Choice C) could alter its integrity and affect drug delivery.
