Nursing Elites

1. Which drug classes are NOT typically used to treat angina?

• A. Calcium channel blockers
• B. Organic nitrates
• C. Alpha blockers
• D. Beta blockers

Correct answer: C

Rationale: Angina is primarily treated with calcium channel blockers, organic nitrates, and beta blockers. Alpha blockers are not commonly used in the treatment of angina. Calcium channel blockers help dilate blood vessels, decreasing the workload on the heart. Organic nitrates relax and widen blood vessels, improving blood flow and reducing the heart's workload. Beta blockers reduce the heart rate and blood pressure, decreasing the heart's demand for oxygen. Alpha blockers are more commonly used to treat conditions like hypertension and benign prostatic hyperplasia.

2. A client has been prescribed Aspirin for prevention of cardiovascular disease. Which of the following findings indicates the medication is effective?

• A. The client has a decrease in troponin levels.
• B. The client has a regular heart rhythm.
• C. The client experiences a decrease in episodes of angina.
• D. The client's blood pressure remains stable.

Correct answer: C

Rationale: The correct answer is C. A decrease in episodes of angina is an indicator of Aspirin's effectiveness in preventing cardiovascular events. Aspirin works by inhibiting platelet aggregation, thereby reducing the formation of blood clots that could lead to angina episodes or more severe cardiovascular complications. Choices A, B, and D are incorrect because troponin levels, heart rhythm, and blood pressure are not direct indicators of Aspirin's effectiveness in preventing cardiovascular events.

3. A nurse orienting a newly licensed nurse is reviewing the procedure for taking a telephone prescription. Which of the following statements should the nurse identify as an indication that the newly licensed nurse understands the process?

• A. A second nurse enters the prescription into the client's medical record.
• B. Another nurse should listen to the phone call.
• C. The provider can clarify the prescription when he signs the health record.
• D. I should omit the 'read back' if this is a one-time prescription.

Correct answer: B

Rationale: The correct answer is B: 'Another nurse should listen to the phone call.' When taking a telephone prescription, having another nurse listen to the phone call is essential to prevent errors in communication. This process helps ensure accuracy and reduces the risk of misinterpretation. Choice A is incorrect because entering the prescription into the client's medical record is not related to verifying the accuracy of the telephone prescription. Choice C is incorrect as the provider clarifying the prescription upon signing the health record doesn't address the immediate need for verification during the phone call. Choice D is incorrect because the 'read back' is a crucial step in confirming the accuracy of all prescriptions, regardless of whether they are one-time or recurring.

4. A client in the operating room received a dose of Succinylcholine, leading to muscle rigidity and a sudden rise in body temperature. The nurse should anticipate a prescription for which of the following medications?

• A. Neostigmine
• B. Naloxone
• C. Dantrolene
• D. Vecuronium

Correct answer: C

Rationale: Muscle rigidity and a sudden rise in temperature are indicative of malignant hyperthermia, a potential complication of succinylcholine. Dantrolene is the drug of choice to treat malignant hyperthermia as it acts on skeletal muscles to reduce metabolic activity and counteract the symptoms. Neostigmine (Choice A) is used to reverse the effects of non-depolarizing neuromuscular blocking agents, not for malignant hyperthermia. Naloxone (Choice B) is an opioid antagonist used for opioid overdose. Vecuronium (Choice D) is a non-depolarizing neuromuscular blocking agent and is not the appropriate medication for malignant hyperthermia.

5. A client with a UTI and a history of recurrent infections asks why the provider has not yet prescribed an antibiotic. The nurse should explain that the provider has to wait for the results of which of the following laboratory tests to identify which antibiotic to prescribe?

• A. Gram stain
• B. Culture
• C. Sensitivity
• D. Specific gravity

Correct answer: C

Rationale: In the case of a UTI, a sensitivity test is crucial as it identifies the most effective antibiotic to target the specific microorganism causing the infection. This test helps in prescribing the appropriate antibiotic for successful treatment and preventing antibiotic resistance. While a Gram stain and culture are important in diagnosing a UTI, the sensitivity test specifically determines the most suitable antibiotic. Specific gravity, on the other hand, is not related to identifying the appropriate antibiotic for a UTI.
