Nursing Elites

1. The nurse is providing discharge teaching to a client with coronary artery disease (CAD). Which of the following statements by the client indicates a need for further teaching?

• A. I will take my medication only when I have chest pain.
• B. I will follow a heart-healthy diet and exercise regularly.
• C. I will avoid smoking and limit alcohol intake.
• D. I will contact my doctor if I experience chest pain or shortness of breath.

Correct answer: A

Rationale: The statement indicates a misunderstanding because medication for CAD should be taken as prescribed, not only when chest pain occurs.

2. A patient is diagnosed with Mycoplasma pneumonia. Which antibiotic will the nurse expect the provider to order to treat this infection?

• A. Azithromycin (Zithromax)
• B. Clarithromycin (Biaxin)
• C. Erythromycin (E-Mycin)
• D. Fidaxomicin (Dificid)

Correct answer: C

Rationale: Erythromycin is the drug of choice for treating Mycoplasma pneumonia. Mycoplasma pneumonia is typically sensitive to macrolide antibiotics, with erythromycin being one of the first-line agents. Azithromycin and clarithromycin are also effective in treating Mycoplasma pneumonia, but erythromycin is specifically mentioned as the drug of choice in this context. Fidaxomicin, on the other hand, is not indicated for the treatment of Mycoplasma pneumonia and is primarily used to treat Clostridium difficile infections.

3. Why is the combination drug trimethoprim-sulfamethoxazole (TMP-SMX) necessary?

• A. To broaden the antibacterial spectrum.
• B. To decrease bacterial resistance.
• C. To improve the taste.
• D. To minimize toxic effects.

Correct answer: B

Rationale: The correct answer is B: To decrease bacterial resistance. Trimethoprim-sulfamethoxazole (TMP-SMX) is a combination drug used to prevent bacterial resistance to sulfonamides. It works by targeting different steps in the bacterial metabolic pathway, making it harder for bacteria to develop resistance. Choice A is incorrect because the combination does not broaden the antibacterial spectrum; instead, it enhances effectiveness against specific bacteria. Choice C is incorrect as taste improvement is not the primary reason for combining these drugs. Choice D is incorrect because while combination therapy can sometimes help minimize toxic effects, the primary purpose in this case is to address bacterial resistance.

4. A nurse assesses clients on the medical-surgical unit. Which client is at greatest risk for bladder cancer?

• A. A 25-year-old female with a history of sexually transmitted diseases
• B. A 42-year-old male who has worked in a lumber yard for 10 years
• C. A 55-year-old female who has had numerous episodes of bacterial cystitis
• D. An 86-year-old male with a 50–pack-year cigarette smoking history

Correct answer: D

Rationale: The correct answer is D. The greatest risk factor for bladder cancer is a long history of tobacco use, which is reflected in an 86-year-old male with a 50–pack-year cigarette smoking history. Smoking is a well-established risk factor for developing bladder cancer. Choices A, B, and C are not directly linked to an increased risk of bladder cancer. While sexually transmitted diseases, certain occupational exposures, and recurrent urinary tract infections may pose other health risks, they are not specifically associated with an elevated risk of bladder cancer.

5. A client who has heart failure is admitted with a serum potassium level of 2.9 mEq/L. Which action is most important for the nurse to implement?

• A. Administer 20 mEq of potassium chloride.
• B. Initiate continuous cardiac monitoring.
• C. Arrange a consultation with the dietitian.
• D. Educate about the side effects of diuretics.

Correct answer: B

Rationale: Hypokalemia, defined as a serum potassium level below the normal range of 3.5 to 5 mEq/L, can lead to changes in myocardial irritability and ECG waveform, potentially causing life-threatening dysrhythmias. Therefore, the priority action for the nurse is to initiate continuous cardiac monitoring to promptly detect any abnormal heart rhythms or ventricular ectopy. This monitoring is crucial for assessing the impact of potassium replacement therapy on the cardiac rhythm and ensuring the safety of the client. While administering potassium chloride is important for correcting the hypokalemia, it should occur after cardiac monitoring is in place. Consulting with a dietitian and educating about diuretic side effects are relevant aspects of care but are not the immediate priority in this situation where cardiac monitoring takes precedence for timely intervention.
