Question 1 of 5
Based on a client's serum digoxin level, the client is diagnosed with digoxin toxicity. Which action should the nurse expect to implement?
Correct Answer: A
Rationale: Checking acid-base and electrolyte values is critical for digoxin toxicity, as imbalances like hypokalemia worsen toxicity. Changing routes, cardioversion, or potassium administration are not immediate without assessment.
Question 2 of 5
A client with irritable bowel syndrome starts a new prescription for dicyclomine, an anticholinergic medication. The client reports the onset of sensitivity to bright sunlight and a dry mouth. How should the nurse respond?
Correct Answer: D
Rationale: Photosensitivity and dry mouth are common dicyclomine side effects. Providing management instructions (e.g., sunglasses, hard candy) promotes comfort and compliance. Checking administration, stopping the drug, or scheduling an appointment are secondary without severe symptoms.
Question 3 of 5
A female client with mild depression reports to the nurse recently starting St. John's wort. Which information provided by the client requires further instruction?
Correct Answer: D
Rationale: St. John's wort reduces oral contraceptive effectiveness, necessitating additional contraception. Hard candy for dry mouth, insomnia, and photosensitivity are correct understandings and do not require further instruction.
Question 4 of 5
Based on a client's serum digoxin level, the client is diagnosed with digoxin toxicity. Which action should the nurse expect to implement?
Correct Answer: A
Rationale: Checking acid-base and electrolyte values is critical for digoxin toxicity, as imbalances like hypokalemia worsen toxicity. Changing routes, cardioversion, or potassium administration are not immediate without assessment.
Question 5 of 5
A client is receiving tamsulosin for the management of urinary retention due to benign prostatic hyperplasia (BPH). Which instruction is most important for the nurse to provide?
Correct Answer: A,B
Rationale: A: Hard candy alleviates dry mouth, a common tamsulosin side effect. B: Insomnia is a potential side effect, and clients should be informed. However, the most critical instruction is typically to stand/sit slowly to prevent orthostatic hypotension, which is not listed. Dry mouth and insomnia are valid but secondary concerns.
