Nursing Elites

1. A practical nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving theophylline. Which symptom indicates that the client may be experiencing theophylline toxicity?

• A. Bradycardia
• B. Tremors
• C. Constipation
• D. Hypotension

Correct answer: B

Rationale: Tremors are a common symptom of theophylline toxicity. Other symptoms that may indicate theophylline toxicity include nausea, vomiting, and seizures. Bradycardia, constipation, and hypotension are not typically associated with theophylline toxicity. It is important for the nurse to monitor the client closely for these signs of toxicity and report them promptly to the healthcare provider to prevent further complications.

2. A client has been diagnosed with open-angle glaucoma. The healthcare provider prescribes pilocarpine 1% eye drops. The nurse explains that which action of this drug makes it a useful treatment for the client's condition?

• A. The ciliary muscle contracts, increasing the outflow of aqueous humor in the eye.
• B. Ciliary muscles are paralyzed to decrease accommodation.
• C. Bilateral mydriasis with cycloplegia is accomplished.
• D. The production of aqueous humor in the eyes is decreased.

Correct answer: A

Rationale: Pilocarpine, a cholinergic agent, stimulates the ciliary muscle to contract, which opens the trabecular meshwork and facilitates the outflow of aqueous humor, reducing intraocular pressure. This mechanism helps in managing open-angle glaucoma by improving drainage and lowering pressure within the eye. Choice A is correct because the contraction of the ciliary muscle increases the outflow of aqueous humor, aiding in the treatment of open-angle glaucoma. Choices B, C, and D are incorrect because they do not describe the mechanism of action of pilocarpine in treating glaucoma.

3. A client with a history of myocardial infarction is prescribed atorvastatin. The nurse should monitor the client for which potential adverse effect?

• A. Liver damage
• B. Kidney damage
• C. Muscle pain
• D. Increased appetite

Correct answer: C

Rationale: The correct answer is C: Muscle pain. Atorvastatin can cause muscle pain, which may indicate rhabdomyolysis, a serious adverse effect. Rhabdomyolysis is a condition where muscle breakdown releases a protein (myoglobin) into the bloodstream, potentially leading to kidney damage. Liver damage (choice A) is a less common side effect of atorvastatin compared to muscle pain. Kidney damage (choice B) is not a direct adverse effect of atorvastatin but can occur indirectly if rhabdomyolysis is severe. Increased appetite (choice D) is not a known adverse effect of atorvastatin.

4. The client is receiving vancomycin, and the nurse plans to draw blood for a peak and trough to determine... the best timing for these levels?

• A. Midway through administration of the IV dose and 30 minutes before the next
• B. Two hours after completion of the IV dose and 30 minutes before the next
• C. Two hours after completion of the IV dose and one hour before the next
• D. Immediately after completion of the IV dose and 30 minutes before

Correct answer: B

Rationale: To accurately determine peak and trough levels of vancomycin, blood should be drawn two hours after the completion of the IV dose and 30 minutes before the next dose. This timing allows for appropriate assessment of the drug levels in the body, ensuring accurate monitoring of therapeutic and toxic concentrations. Choice A is incorrect as drawing blood midway through administration does not provide an accurate peak level. Choice C is incorrect as drawing blood one hour before the next dose does not represent the trough level. Choice D is incorrect because drawing blood immediately after completion of the IV dose does not allow enough time for the drug to reach peak levels.

5. A client with hypertension is prescribed clonidine. The nurse should monitor the client for which potential side effect?

• A. Hypotension
• B. Tachycardia
• C. Dizziness
• D. Hyperglycemia

Correct answer: A

Rationale: The correct answer is A: Hypotension. Clonidine, a medication used to treat hypertension, can cause a lowering of blood pressure leading to hypotension as a potential side effect. Monitoring for hypotension is essential to prevent complications such as dizziness, fainting, or falls. Option B, Tachycardia, is incorrect as clonidine typically causes bradycardia or a decreased heart rate. Option C, Dizziness, can occur due to hypotension caused by clonidine. Option D, Hyperglycemia, is not a common side effect associated with clonidine use.
