1. After the initial dose, which of the following is the priority assessment for a client being treated for acute congestive heart failure with intravenously administered bumetanide?
- A. Monitoring weight loss
- B. Monitoring temperature
- C. Monitoring blood pressure
- D. Monitoring potassium level
Correct answer: C
Rationale: The correct answer is monitoring blood pressure. Bumetanide is a loop diuretic, and monitoring blood pressure is crucial as hypotension is a common side effect. Hypotension can further worsen the condition of a patient with congestive heart failure, so assessing and managing blood pressure is a priority after administering bumetanide.
2. 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.
3. A client is receiving bethanechol chloride (Urecholine). The nurse monitors the client for adverse effects of the medication and should observe for which of the following?
- A. Bradycardia
- B. Constipation
- C. Hypertension
- D. Dry mouth
Correct answer: A
Rationale: Corrected Rationale: Bethanechol chloride (Urecholine) stimulates muscarinic receptors, which can lead to bradycardia as an adverse effect. Monitoring for bradycardia is crucial when administering this medication. Constipation, hypertension, and dry mouth are not typically associated with the effects of bethanechol chloride. Bradycardia is the correct adverse effect to monitor for, making option A the correct answer. Constipation, hypertension, and dry mouth are not commonly seen with bethanechol chloride and are therefore incorrect choices.
4. A client has been taking isoniazid (INH) for 2 months. The client complains to a nurse about numbness, paresthesias, and tingling in the extremities. The nurse interprets that the client is experiencing:
- A. Hypercalcemia
- B. Peripheral neuritis
- C. Small blood vessel spasm
- D. Impaired peripheral circulation
Correct answer: B
Rationale: The client's symptoms of numbness, paresthesias, and tingling in the extremities indicate peripheral neuritis, a common side effect of isoniazid (INH). This condition can be managed by supplementing with pyridoxine (vitamin B6) to minimize the symptoms.
5. A client is prescribed amlodipine (Norvasc) for hypertension. Which side effect should the nurse instruct the client to report to the healthcare provider?
- A. Dizziness
- B. Constipation
- C. Peripheral edema
- D. Dry cough
Correct answer: C
Rationale: The correct answer is C, 'Peripheral edema.' Amlodipine (Norvasc) can cause peripheral edema, which is an accumulation of fluid in the extremities and should be reported to the healthcare provider. Dizziness and constipation are possible side effects of amlodipine but are generally less concerning. Dry cough is more commonly associated with ACE inhibitors, not calcium channel blockers like amlodipine.
