Nursing Elites

1. The nurse is preparing to give a dose of a cephalosporin medication to a patient who has been receiving the antibiotic for 2 weeks. The nurse notes ulcers on the patient’s tongue and buccal mucosa. Which action will the nurse take?

• A. Hold the drug and notify the provider.
• B. Obtain an order to culture the oral lesions.
• C. Gather emergency equipment to prepare for anaphylaxis.
• D. Report a possible superinfection side effect of the cephalosporin.

Correct answer: D

Rationale: The nurse should report a possible superinfection side effect of the cephalosporin to the physician as the patient's symptoms may indicate a superinfection that requires treatment. Holding the drug is not necessary unless directed by the provider. Culturing the lesions is not indicated for this situation. There is no evidence to suggest impending anaphylaxis based on the patient's symptoms.

2. Which lab result would be most indicative of renal failure?

• A. Elevated creatinine levels.
• B. Low potassium levels.
• C. Low calcium levels.
• D. High sodium levels.

Correct answer: A

Rationale: The correct answer is A: Elevated creatinine levels. Creatinine is a waste product that is normally filtered by the kidneys. Elevated creatinine levels indicate impaired kidney function, which is commonly seen in renal failure. Choice B, low potassium levels, is not typically associated with renal failure. In fact, renal failure is more likely to cause high potassium levels due to the kidneys' inability to excrete potassium effectively. Choice C, low calcium levels, are not directly indicative of renal failure. Renal failure can lead to disturbances in calcium levels, but low calcium levels alone are not a specific marker for renal failure. Choice D, high sodium levels, are also not typically associated with renal failure. In renal failure, there may be disturbances in sodium levels, but high sodium levels alone are not a direct indicator of renal failure.

3. The nurse is caring for a patient who is receiving isotonic intravenous (IV) fluids at an infusion rate of 125 mL/hour. The nurse performs an assessment and notes a heart rate of 102 beats per minute, a blood pressure of 160/85 mm Hg, and crackles auscultated in both lungs. Which action will the nurse take?

• A. Decrease the IV fluid rate and notify the provider.
• B. Increase the IV fluid rate and notify the provider.
• C. Request an order for a colloidal IV solution.
• D. Request an order for a hypertonic IV solution.

Correct answer: A

Rationale: The patient is showing signs of fluid volume excess, indicated by crackles in both lungs, increased heart rate, and elevated blood pressure. To address this, the nurse should decrease the IV fluid rate and notify the provider. Increasing the IV fluid rate would worsen fluid overload. Requesting colloidal or hypertonic IV solutions would exacerbate the issue by pulling more fluids into the intravascular space, leading to further volume overload.

4. Which of the following assessments is the most important for a patient receiving IV potassium?

• A. Respiratory rate
• B. Heart rate
• C. Blood pressure
• D. Oxygen saturation

Correct answer: C

Rationale: The most important assessment for a patient receiving IV potassium is monitoring blood pressure. IV potassium can cause significant changes in cardiac function, leading to adverse effects such as arrhythmias and cardiac arrest. While respiratory rate, heart rate, and oxygen saturation are important parameters to monitor in clinical practice, blood pressure takes precedence in patients receiving IV potassium due to its direct impact on cardiovascular function. Changes in blood pressure can be an early indicator of potassium-induced cardiac complications, making it crucial to monitor closely during administration.

5. A patient presents with severe chest pain radiating to the left arm. Which of the following diagnostic tests is the priority?

• A. Complete blood count (CBC)
• B. Electrocardiogram (ECG)
• C. Chest X-ray
• D. Serum electrolytes

Correct answer: B

Rationale: In a patient presenting with severe chest pain radiating to the left arm, the priority diagnostic test is an Electrocardiogram (ECG) to assess for myocardial infarction. An ECG can quickly identify changes indicative of ischemia or infarction, guiding prompt management. A Complete Blood Count (CBC) may provide some information but is not the primary test for evaluating chest pain related to myocardial infarction. A Chest X-ray can be useful in assessing lung pathologies or certain cardiac conditions; however, it does not provide immediate information on myocardial infarction, making it a secondary option in this scenario. Serum electrolytes may become important in later stages but do not offer immediate insights into myocardial infarction. Therefore, they are a lower priority compared to obtaining an ECG for timely diagnosis and intervention.
