1. A client with portosystemic encephalopathy is receiving oral lactulose (Chronulac) daily. The nurse assesses which of the following to determine medication effectiveness?
- A. Lung sounds
- B. Blood pressure
- C. Blood ammonia level
- D. Serum potassium level
Correct answer: C
Rationale: In portosystemic encephalopathy, the liver's ability to detoxify ammonia is impaired, leading to elevated blood ammonia levels, which can cause neurological symptoms such as encephalopathy. Lactulose is given to reduce ammonia levels by promoting its excretion through the bowel. Therefore, assessing the blood ammonia level is crucial to determine the effectiveness of lactulose therapy in managing portosystemic encephalopathy.
2. Alendronate (Fosamax) is prescribed for a client with osteoporosis. The client taking this medication is instructed to:
- A. Take the medication at bedtime.
- B. Take the medication in the morning with breakfast.
- C. Lie down for 30 minutes after taking the medication.
- D. Take the medication with a full glass of water after rising in the morning.
Correct answer: D
Rationale: Alendronate (Fosamax) should be taken with a full glass of water after rising in the morning to prevent gastrointestinal side effects and increase absorption. Taking the medication with a full glass of water and in an upright position after waking up helps decrease the risk of esophageal irritation and enhances the drug's effectiveness by ensuring proper absorption in the gastrointestinal tract.
3. A client with severe acne is seen in the clinic, and the healthcare provider prescribes isotretinoin. The nurse reviews the client's medication record and would contact the healthcare provider if the client is taking which medication?
- A. Vitamin A
- B. Digoxin (Lanoxin)
- C. Furosemide (Lasix)
- D. Phenytoin (Dilantin)
Correct answer: A
Rationale: Isotretinoin is a metabolite of vitamin A, which can lead to toxicity when taken together. Therefore, it is crucial to avoid concurrent use of vitamin A supplements with isotretinoin. Contacting the healthcare provider to discuss discontinuing vitamin A supplements is important to prevent potential adverse effects. Choices B, C, and D are incorrect as they are not known to interact significantly with isotretinoin.
4. A client is receiving an intravenous (IV) infusion of an antineoplastic medication. During the infusion, the client complains of pain at the insertion site. The nurse notes redness and swelling at the site, along with a slowed infusion rate. What is the appropriate action for the nurse to take?
- A. Notify the healthcare provider.
- B. Administer pain medication to reduce discomfort.
- C. Apply ice and maintain the infusion rate as prescribed.
- D. Elevate the extremity of the IV site and slow the infusion rate.
Correct answer: A
Rationale: When a client complains of pain at the IV insertion site, and there are signs of extravasation such as redness and swelling, it is crucial to notify the healthcare provider immediately. Extravasation of antineoplastic medications can cause tissue damage, pain, and necrosis if they escape into surrounding tissues. Prompt action is necessary to prevent further complications and ensure appropriate management of the situation. Administering pain medication, applying ice, or elevating the extremity are not appropriate actions in cases of suspected extravasation. These actions do not address the underlying issue of potential tissue damage and necrosis that can occur due to the leakage of antineoplastic medication.
5. A client is on nicotinic acid (niacin) for hyperlipidemia and the nurse provides instructions to the client about the medication. Which statement by the client would indicate an understanding of the instructions?
- A. It is not necessary to avoid the use of alcohol.
- B. The medication should be taken with meals to decrease flushing.
- C. Clay-colored stools are a common side effect and should not be of concern.
- D. Ibuprofen (Motrin) taken 30 minutes before the nicotinic acid should decrease the flushing.
Correct answer: D
Rationale: Aspirin or a nonsteroidal anti-inflammatory drug can be taken 30 minutes before taking the medication to decrease flushing. Alcohol consumption needs to be avoided because it will enhance this side effect. The medication should be taken with meals, this will decrease gastrointestinal upset. Taking the medication with meals has no effect on the flushing. Clay-colored stools are a sign of hepatic dysfunction and should be immediately reported to the health care provider (HCP).
