1. A client is being monitored while receiving bethanechol chloride (Urecholine) for urinary retention. Which of the following indicates a therapeutic effect of this medication?
- A. Increased heart rate
- B. Increased peristalsis
- C. Passage of flatus
- D. Urinary output of 50 mL per hour
Correct answer: D
Rationale: Bethanechol chloride (Urecholine) is administered to stimulate the bladder and treat urinary retention. The therapeutic effect is indicated by an increased urinary output, as it demonstrates the medication's ability to prompt the bladder to empty. Increased heart rate and passage of flatus are unrelated to the therapeutic effects of bethanechol. Although bethanechol can increase peristalsis, the primary therapeutic goal is to address urinary retention.
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. What instruction should be included in the client's teaching plan when prescribed montelukast (Singulair) for asthma?
- A. Take the medication as needed for asthma attacks.
- B. Take the medication in the evening.
- C. Increase fluid intake while taking this medication.
- D. Use the medication before exercise.
Correct answer: B
Rationale: The correct instruction to include in the teaching plan for a client prescribed montelukast (Singulair) is to take the medication in the evening. Montelukast is most effective when taken in the evening to provide optimal control of asthma symptoms. It is not intended for use as a rescue medication for asthma attacks. There is no specific recommendation to increase fluid intake or use the medication before exercise in relation to montelukast therapy.
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. 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.
