1. The nurse is preparing to administer amoxicillin (Amoxil) to a patient and learns that the patient previously experienced a rash when taking penicillin. Which action will the nurse take?

A. Administer the amoxicillin and have epinephrine available.
B. Ask the provider to order an antihistamine.
C. Contact the provider to discuss using a different antibiotic.
D. Request an order for a beta-lactamase-resistant drug.

Correct answer: C

Rationale: When a patient has a history of rash from penicillin, it indicates a potential allergic reaction to penicillin and other related drugs, such as amoxicillin. It is crucial to avoid administering penicillins to such patients unless there is no alternative. The nurse's best action in this situation is to contact the provider to discuss using a different antibiotic from a different class. This approach helps prevent potential severe allergic reactions. While epinephrine and antihistamines are used to manage allergic reactions, administering amoxicillin despite the known allergy is not advisable and could lead to serious consequences. Requesting a beta-lactamase-resistant drug does not address the issue of potential allergic reactions in this scenario.

2. An obese client with emphysema who smoked at least a pack of cigarettes daily is admitted after experiencing a sudden increase in dyspnea and activity intolerance. Oxygen therapy is initiated, and it is determined that the client will be discharged with oxygen. Which information is most important for the nurse to emphasize in the discharge teaching plan?

A. Methods for weight loss
B. Guidelines for oxygen use
C. Approaches to conserve energy
D. Strategies for smoking cessation

Correct answer: B

Rationale: In this scenario, the priority for the nurse to emphasize in the discharge teaching plan is the 'Guidelines for oxygen use.' As the client with emphysema is being discharged with oxygen therapy, it is crucial for the nurse to ensure that the client understands how to use oxygen properly to prevent complications and promote effective management of the condition. While weight loss, conserving energy, and smoking cessation are important aspects of care for this client, in this specific case, ensuring the safe and appropriate use of supplemental oxygen takes precedence to optimize the client's respiratory function and overall well-being.

3. A patient who is being treated for dehydration is receiving 5% dextrose and 0.45% normal saline with 20 mEq/L potassium chloride at a rate of 125 mL/hour. The nurse assuming care for the patient reviews the patient’s serum electrolytes and notes a serum sodium level of 140 mEq/L and a serum potassium level of 3.6 mEq/L. The patient had a urine output of 250 mL during the last 12-hour shift. Which action will the nurse take?

A. Contact the patient’s provider to discuss increasing the potassium chloride to 40 mEq/L.
B. Continue the intravenous fluids as ordered and reassess the patient frequently.
C. Notify the provider and discuss increasing the rate of fluids to 200 mL/hour.
D. Stop the intravenous fluids and notify the provider of the assessment findings.

Correct answer: D

Rationale: The patient’s potassium level is within normal limits, but the decreased urine output indicates the patient should not receive additional IV potassium. Increasing potassium chloride to 40 mEq/L is not needed as the level is normal. Stopping the IV fluids is appropriate due to the decreased urine output, which suggests potential fluid overload. The nurse should notify the provider of the assessment findings for further management. Increasing the rate of fluids to 200 mL/hour is not recommended without addressing the decreased urine output first.

4. What information will the nurse provide when counseling a patient starting a sulfonamide drug for a urinary tract infection?

A. Drink several quarts of water daily.
B. If stomach upset occurs, avoid taking antacids.
C. Limit sun exposure to avoid skin reactions.
D. Report any sore throat promptly.

Correct answer: A

Rationale: The correct answer is A: Drink several quarts of water daily. This advice aims to prevent crystalluria, a potential side effect of sulfonamide drugs. Option B is incorrect because antacids should not be taken with sulfonamides as they can decrease drug absorption. Option C is incorrect as sulfonamides can increase sensitivity to sunlight, not requiring sun exposure limitations but sun protection measures. Option D is incorrect because a sore throat could indicate a more serious adverse effect and should be promptly reported for evaluation.

5. A client who underwent lobectomy 24 hours ago has not had any chest tube drainage for the past hour. What should the nurse do first?

A. Contacts the physician
B. Checks for kinks in the drainage system
C. Checks the client’s blood pressure and heart rate
D. Connects a new drainage system to the client’s chest tube

Correct answer: B

Rationale: When a chest tube is not draining, the nurse's initial action should be to check for kinks or clots in the chest drainage system. This step helps to ensure the patency of the system and allows for proper drainage. Checking the client's blood pressure and heart rate is important but not the priority when addressing a lack of chest tube drainage. Contacting the physician is warranted if signs of respiratory distress or mediastinal shift are observed after ruling out kinks or clots. Connecting a new drainage system is done when the fluid chamber is full, following a specific procedure to maintain a closed system and prevent complications.
