1. A client is prescribed allopurinol (Zyloprim) for chronic gout. Which instruction should the nurse include in the teaching plan?
- A. Take the medication with a full glass of water.
- B. Increase your intake of purine-rich foods.
- C. Stop taking the medication if you experience a gout attack.
- D. Take the medication with or without food.
Correct answer: A
Rationale: The correct instruction for a client prescribed allopurinol (Zyloprim) for chronic gout is to take the medication with a full glass of water. This helps prevent kidney stones which can be a side effect of the medication. It is important for the client to avoid purine-rich foods to help manage gout symptoms. They should continue taking the medication even during a gout attack as prescribed by the healthcare provider. Allopurinol can be taken with or without food, so there is no need to take it on an empty stomach. Therefore, option A is the correct choice. Options B, C, and D are incorrect as increasing purine-rich foods is not recommended, stopping the medication during a gout attack is not advised, and allopurinol can be taken with or without food.
2. A healthcare professional is preparing to administer digoxin (Lanoxin), 0.125 mg orally, to a client with heart failure. Which vital sign is most important for the healthcare professional to check before administering the medication?
- A. Heart rate
- B. Temperature
- C. Respirations
- D. Blood pressure
Correct answer: A
Rationale: Before administering digoxin, it is essential to assess the client's heart rate as this medication directly affects cardiac function. Monitoring the heart rate helps identify if it is within the acceptable range for administering digoxin. A pulse rate below 60 beats per minute warrants withholding the medication to prevent potential adverse effects like bradycardia or cardiac arrhythmias.
3. A client receives a prescription for methocarbamol (Robaxin), and the nurse reinforces instructions to the client regarding the medication. Which client statement would indicate a need for further instructions?
- A. My urine may turn brown or green.
- B. This medication is prescribed to help relieve my muscle spasms.
- C. If my vision becomes blurred, I need to be concerned about it.
- D. I need to call my doctor if I experience nasal congestion from this medication.
Correct answer: C
Rationale: The correct answer is C because blurred vision is an adverse effect of methocarbamol (Robaxin) and should be reported to a healthcare provider. Choices A, B, and D are all correct statements. Option A informs the client about a possible discoloration of urine, which is a known side effect. Option B correctly explains the purpose of the medication. Option D correctly advises the client to contact their doctor if they experience nasal congestion, which could indicate an adverse reaction.
4. The healthcare provider is analyzing the laboratory results of a client with leukemia who has received a regimen of chemotherapy. Which laboratory value would the healthcare provider specifically note as a result of the massive cell destruction that occurred from the chemotherapy?
- A. Anemia
- B. Decreased platelets
- C. Increased uric acid level
- D. Decreased leukocyte count
Correct answer: C
Rationale: Following chemotherapy for leukemias and lymphomas, hyperuricemia is common due to the massive cell kill. Chemotherapy leads to the rapid destruction of cancer cells, releasing large amounts of nucleic acids, which are broken down into uric acid. Monitoring and managing uric acid levels are crucial to prevent complications such as renal damage and gout.
5. A client is taking docusate sodium (Colace). The nurse monitors which of the following to determine whether the client is experiencing a therapeutic effect from this medication?
- A. Abdominal pain
- B. Reduction in steatorrhea
- C. Hematest-negative stools
- D. Regular bowel movements
Correct answer: D
Rationale: The therapeutic effect of docusate sodium (Colace) is to soften stools and promote regular bowel movements, making option D the correct choice. Monitoring for regular bowel movements would indicate that the medication is working as intended by relieving or preventing constipation. Options A, B, and C are not directly related to the therapeutic effect of docusate sodium. Abdominal pain (option A) is a symptom that might indicate a problem rather than a therapeutic effect. Reduction in steatorrhea (option B) and Hematest-negative stools (option C) are not specific outcomes associated with docusate sodium.
