Nursing Elites

1. 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.

2. A client with a diagnosis of schizophrenia is prescribed quetiapine. The nurse should monitor the client for which potential side effect?

• A. Weight gain
• B. Dry mouth
• C. Nausea
• D. Headache

Correct answer: A

Rationale: Quetiapine is known to cause weight gain as a common side effect. Monitoring the client's weight is crucial to identify any significant changes that may occur due to the medication.

3. A client is receiving heparin to treat a deep vein thrombosis. The nurse should monitor which laboratory result to assist in evaluating the efficacy of the drug?

• A. Platelet count
• B. Prothrombin time
• C. Partial thromboplastin time
• D. Serum levels of protamine sulfate

Correct answer: C

Rationale: The nurse should monitor the partial thromboplastin time to evaluate the efficacy of heparin. Partial thromboplastin time reflects the anticoagulant effect of heparin by measuring the intrinsic pathway of coagulation. Platelet count assesses platelet levels and is not specific to heparin efficacy. Prothrombin time is used to monitor warfarin therapy. Serum levels of protamine sulfate are not used to evaluate the efficacy of heparin.

4. 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.

5. 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.
