Nursing Elites

1. In a client with congestive heart failure, the nurse would be correct in withholding a dose of digoxin without specific instruction from the healthcare provider if the client's

• A. serum digoxin level is 1.5 ng/mL.
• B. blood pressure is 104/68 mmHg.
• C. serum potassium level is 3 mEq/L.
• D. apical pulse is 68/min.

Correct answer: C

Rationale: The correct answer is C. Hypokalemia can precipitate digitalis toxicity in individuals on digoxin, increasing the risk of dangerous dysrhythmias. A serum potassium level of 3 mEq/L is below the normal range (3.5 to 5.5 mEq/L) and indicates hypokalemia, which can potentiate the effects of digoxin. Choices A, B, and D are not directly related to the potential for digitalis toxicity. Serum digoxin level of 1.5 ng/mL is within the therapeutic range, blood pressure of 104/68 mmHg is not a contraindication for administering digoxin, and an apical pulse of 68/min is within the normal range and not a reason to withhold digoxin.

2. The nurse is preparing to administer the first dose of intravenous ceftriaxone (Rocephin) to a patient. When reviewing the patient’s chart, the nurse notes that the patient previously experienced a rash when taking amoxicillin. What is the nurse’s next action?

• A. Administer the drug and observe closely for hypersensitivity reactions.
• B. Ask the provider whether a cephalosporin from a different generation may be used.
• C. Contact the provider to report drug hypersensitivity.
• D. Notify the provider and suggest an oral cephalosporin.

Correct answer: A

Rationale: When a patient has a history of a rash with amoxicillin, a beta-lactam antibiotic like ceftriaxone should be administered cautiously due to a possible cross-reactivity. The nurse should still administer the drug but closely monitor the patient for any signs of hypersensitivity reactions. Asking for a different generation of cephalosporin or suggesting an oral form does not address the potential cross-reactivity issue. Contacting the provider to report drug hypersensitivity would delay care when the patient needs immediate treatment.

3. 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.

4. The nurse assumes care for a patient who is currently receiving a dose of intravenous vancomycin (Vancocin) infusing at 20 mg/min. The nurse notes red blotches on the patient’s face, neck, and chest and assesses a blood pressure of 80/55 mm Hg. Which action will the nurse take?

• A. Request an order for IV epinephrine to treat anaphylactic shock.
• B. Slow the infusion to 10 mg/min and observe the patient closely.
• C. Stop the infusion and obtain an order for a BUN and serum creatinine.
• D. Suspect Stevens-Johnson syndrome and notify the provider immediately.

Correct answer: B

Rationale: When vancomycin is infused too rapidly, “red man” syndrome may occur; the rate should be 10 mg/min to prevent this. This is a toxic reaction, not an allergic one, so epinephrine is not indicated. Stevens-Johnson syndrome is characterized by a rash and fever. Red man syndrome is not related to renal function.

5. In a patient with chronic obstructive pulmonary disease (COPD), which of the following interventions is most important?

• A. Encouraging the patient to stop smoking.
• B. Administering bronchodilators.
• C. Monitoring oxygen saturation.
• D. Providing nutritional support.

Correct answer: C

Rationale: Monitoring oxygen saturation is the most important intervention in a patient with COPD because it helps assess the adequacy of oxygenation. In COPD, patients often have compromised lung function, leading to decreased oxygen levels in the blood. Monitoring oxygen saturation allows healthcare providers to promptly identify and address any potential hypoxemia, which is vital in managing COPD exacerbations. While encouraging the patient to stop smoking (Choice A) is critical for long-term management, monitoring oxygen saturation takes precedence in the immediate care of a COPD patient. Administering bronchodilators (Choice B) and providing nutritional support (Choice D) are important aspects of managing COPD but are secondary to monitoring oxygen saturation, which directly impacts the patient's oxygenation status.
