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 client is taking levothyroxine (Synthroid) for hypothyroidism. Which symptom would indicate to the nurse that the client is taking too much medication?

A. Bradycardia
B. Lethargy
C. Tremors
D. Constipation

Correct answer: C

Rationale: When a client is taking an excessive dose of levothyroxine (Synthroid), it can lead to symptoms of hyperthyroidism. Tremors are a common sign of excessive medication, along with tachycardia and insomnia. Bradycardia, lethargy, and constipation are typical symptoms of hypothyroidism, indicating that the client may require a higher dose of levothyroxine rather than too much.

3. 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.

4. The home health care nurse is visiting a client who was recently diagnosed with type 2 diabetes mellitus. The client is prescribed repaglinide (Prandin) and metformin (Glucophage) and asks the nurse to explain these medications. The nurse should reinforce which instructions to the client? Select one that doesn't apply.

A. Diarrhea can occur secondary to the metformin.
B. The repaglinide is not taken if a meal is skipped.
C. The repaglinide is taken 30 minutes before eating.
D. Nausea and vomiting

Correct answer: D

Rationale: Repaglinide is a rapid-acting oral hypoglycemic that should be taken before meals and withheld if the client does not eat. Hypoglycemia is a side effect of repaglinide, so carrying a simple sugar is essential. Metformin decreases hepatic glucose production and can cause diarrhea. Muscle pain may occur as an adverse effect and should be reported to the HCP.

5. A client with trigeminal neuralgia tells the nurse that acetaminophen (Tylenol) is taken on a frequent daily basis for relief of generalized discomfort. The nurse reviews the client's laboratory results and determines that which of the following indicates toxicity associated with the medication?

A. Sodium of 140 mEq/L
B. Prothrombin time of 12 seconds
C. Platelet count of 400,000 cells/mm³
D. A direct bilirubin level of 2 mg/dL

Correct answer: D

Rationale: A direct bilirubin level of 2 mg/dL indicates liver damage, which can be caused by an overdose of acetaminophen. Acetaminophen toxicity can lead to liver injury, manifesting as elevated bilirubin levels and other liver function test abnormalities.
