Nursing Elites

1. Oxybutynin chloride (Ditropan XL) is prescribed for a client with neurogenic bladder. Which sign would indicate a possible toxic effect related to this medication?

• A. Pallor
• B. Drowsiness
• C. Bradycardia
• D. Restlessness

Correct answer: D

Rationale: Signs of toxicity related to oxybutynin chloride (Ditropan XL) include central nervous system excitation, such as nervousness, restlessness, hallucinations, and irritability. Other signs of toxicity may include hypotension or hypertension, confusion, tachycardia, a flushed or red face, and signs of respiratory depression. Restlessness is a sign of central nervous system excitation, which can indicate a possible toxic effect of this medication.

2. A nurse reinforces discharge instructions to a postoperative client who is taking warfarin sodium (Coumadin). Which statement, if made by the client, reflects the need for further teaching?

• A. I will take my pills every day at the same time.
• B. I will be certain to avoid alcohol consumption.
• C. I have already called my family to pick up a Medic-Alert bracelet.
• D. I will take Ecotrin (enteric-coated aspirin) for my headaches because it is coated.

Correct answer: D

Rationale: Ecotrin is an aspirin-containing product and should be avoided. Clients should avoid alcohol consumption, take prescribed medication at the same time each day, and use a Medic-Alert bracelet for emergency information.

3. The burn client is receiving treatments of topical mafenide acetate (Sulfamylon) to the site of injury. The nurse monitors the client, knowing that which of the following indicates that a systemic effect has occurred?

• A. Hyperventilation
• B. Elevated blood pressure
• C. Local pain at the burn site
• D. Local rash at the burn site

Correct answer: A

Rationale: Hyperventilation is an indication of a systemic effect of mafenide acetate (Sulfamylon) due to its potential to cause acidosis by suppressing renal excretion of acid. If hyperventilation occurs, the medication should be discontinued to prevent further complications.

4. The nurse provides medication instructions to an older hypertensive client who is taking 20 mg of lisinopril (Prinivil, Zestril) orally daily. The nurse evaluates the need for further teaching when the client states which of the following?

• A. I can skip a dose once a week.
• B. I need to change my position slowly.
• C. I take the pill after breakfast each day.
• D. If I get a bad headache, I should call my doctor immediately.

Correct answer: A

Rationale: Lisinopril should be taken daily as prescribed and not skipped. Skipping doses can lead to ineffective treatment.

5. Tamoxifen is prescribed for the client with metastatic breast carcinoma. The nurse understands that the primary action of this medication is to:

• A. Increase DNA and RNA synthesis.
• B. Promote the biosynthesis of nucleic acids.
• C. Increase estrogen concentration and estrogen response.
• D. Compete with estradiol for binding to estrogen in tissues containing high concentrations of receptors.

Correct answer: D

Rationale: The primary action of tamoxifen, an antineoplastic medication used in metastatic breast carcinoma, is to compete with estradiol for binding to estrogen receptors in tissues with high receptor concentrations. By doing so, tamoxifen reduces DNA synthesis and estrogen response, leading to its therapeutic effect in inhibiting the growth of estrogen-sensitive breast cancer cells.
