Nursing Elites

1. 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.

2. The nurse is providing teaching to a patient who will begin taking a cephalosporin to treat an infection. Which statement by the patient indicates a need for further teaching?

• A. I may stop taking the medication if my symptoms clear up.
• B. I should eat yogurt while taking this medication.
• C. I should stop taking the drug and call my provider if I develop a rash.
• D. I will not consume alcohol while taking this medication.

Correct answer: A

Rationale: Patients should take all of an antibiotic regimen even after symptoms clear to ensure complete treatment of the infection.

3. The nurse is teaching a nursing student about the minimal effective concentration (MEC) of antibiotics. Which statement by the nursing student indicates understanding of this concept?

• A. A serum drug level greater than the MEC ensures that the drug is bacteriostatic.
• B. A serum drug level greater than the MEC broadens the spectrum of the drug.
• C. A serum drug level greater than the MEC helps eradicate bacterial infections.
• D. A serum drug level greater than the MEC increases the therapeutic index.

Correct answer: C

Rationale: The MEC is the minimum amount of drug needed to halt the growth of a microorganism. A level greater than the MEC helps eradicate infections. Drugs at or above the MEC are usually bactericidal, not bacteriostatic. Therefore, choice A is incorrect. Broadening the spectrum of a drug refers to its range of activity against different microorganisms, which is not directly related to MEC. Thus, choice B is incorrect. Increasing the therapeutic index involves maximizing the effectiveness of a drug while minimizing its toxicity, which is not specifically related to MEC. Therefore, choice D is also incorrect.

4. Which of the following is a key symptom of myocardial infarction (MI)?

• A. Chest pain.
• B. Shortness of breath.
• C. Nausea.
• D. Fatigue.

Correct answer: A

Rationale: The correct answer is A: Chest pain. Chest pain is a hallmark symptom of myocardial infarction (MI) due to inadequate blood flow to the heart muscle. This pain can be severe, crushing, or squeezing, and may radiate to the left arm, jaw, or back. Shortness of breath (choice B), nausea (choice C), and fatigue (choice D) can accompany MI but are not as specific or characteristic as chest pain in diagnosing this condition. Therefore, chest pain is the primary symptom to recognize for suspected MI.

5. When preparing a client who has had a total laryngectomy for discharge, what instruction is most important for the nurse to include in the discharge teaching?

• A. Recommend that the client carry suction equipment at all times.
• B. Instruct the client to have writing materials with them at all times.
• C. Tell the client to carry a medic alert card stating that they are a total neck breather.
• D. Tell the client not to travel alone.

Correct answer: C

Rationale: The most crucial instruction for a client who has had a total laryngectomy is to carry a medic alert card stating that they are a total neck breather. This is important because if they experience a cardiac arrest, mouth-to-neck breathing may be required. Choice A about carrying suction equipment is not the most critical as the client may not always need it. Choice B is not as essential as having a medic alert card. Choice D is not directly related to the client's safety due to their laryngectomy.
