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. The client with squamous cell carcinoma of the larynx is receiving bleomycin intravenously. The nurse caring for the client anticipates that which diagnostic study will be prescribed?
- A. Echocardiography
- B. Electrocardiography
- C. Cervical radiography
- D. Pulmonary function studies
Correct answer: D
Rationale: Bleomycin, when administered intravenously, can lead to interstitial pneumonitis and potentially progress to pulmonary fibrosis. Therefore, pulmonary function studies are essential to monitor lung function and detect any early signs of pulmonary toxicity. Other tests, such as regular pulmonary assessments, should also be conducted to ensure the safety and well-being of the client.
3. The client has a PRN prescription for ondansetron (Zofran). For which condition should this medication be administered to the postoperative client?
- A. Paralytic ileus
- B. Incisional pain
- C. Urinary retention
- D. Nausea and vomiting
Correct answer: D
Rationale: Ondansetron, also known as Zofran, is an antiemetic medication primarily used to treat nausea and vomiting. In the postoperative setting, it is commonly administered to manage postoperative nausea and vomiting, which are frequent occurrences after surgery. Ondansetron works by blocking serotonin, a natural substance in the body that can trigger nausea and vomiting. It is also utilized to manage chemotherapy-induced nausea and vomiting. Therefore, the correct condition for which ondansetron should be administered to the postoperative client is nausea and vomiting.
4. A client is learning how to mix regular insulin and NPH insulin in the same syringe. Which action, if performed by the client, indicates the need for further teaching?
- A. Withdraws the NPH insulin first
- B. Withdraws the regular insulin first
- C. Injects air into the NPH insulin vial first
- D. Injects an amount of air equal to the desired dose of insulin into the vial
Correct answer: A
Rationale: When mixing regular insulin with another insulin preparation, it is crucial to withdraw the regular insulin first to prevent contamination. NPH insulin should be drawn after the regular insulin to maintain the integrity of each insulin type. Therefore, if the client withdraws the NPH insulin first, it indicates the need for further teaching. Choice B is correct as withdrawing regular insulin first is the appropriate step. Choice C is incorrect as air should be injected into the vial containing the regular insulin to maintain pressure. Choice D is incorrect as injecting air equal to the desired dose of insulin into the vial is a correct step in preparing the insulin for withdrawal.
5. Phenazopyridine hydrochloride (Pyridium) is prescribed for a client for symptomatic relief of pain resulting from a lower urinary tract infection. The nurse reinforces to the client:
- A. To take the medication after meals
- B. To take the medication before meals
- C. To discontinue the medication if a headache occurs
- D. That a reddish-orange discoloration of the urine may occur
Correct answer: D
Rationale: The nurse should instruct the client that a reddish-orange discoloration of urine may occur. The nurse should also educate the client that this discoloration can stain fabric. It is recommended to take the medication after meals to reduce the possibility of gastrointestinal upset. While a headache is an occasional side effect of the medication, it does not warrant discontinuation of the medication.
