1. When a patient starts taking amoxicillin, which foods should the nurse instruct the patient to avoid?
- A. Green leafy vegetables
- B. Beef and other red meat
- C. Coffee, tea, and colas
- D. Acidic fruits and juices
Correct answer: D
Rationale: The correct answer is D: Acidic fruits and juices. Amoxicillin can be irritating to the stomach, so avoiding acidic fruits and juices is recommended to reduce stomach discomfort or potential interactions. Green leafy vegetables (Choice A), beef and other red meat (Choice B), and coffee, tea, and colas (Choice C) are not typically contraindicated with amoxicillin. It is important to focus on acidic foods and beverages to promote comfort and effectiveness of the medication.
2. A client with chronic renal failure is receiving epoetin alfa (Epogen). The nurse should assess the client for which of the following complications?
- A. Hypertension.
- B. Hypotension.
- C. Hyperglycemia.
- D. Edema.
Correct answer: A
Rationale: The correct answer is A: Hypertension. Epoetin alfa (Epogen) is known to increase blood pressure by stimulating red blood cell production. Monitoring for hypertension is crucial to prevent complications such as heart failure or stroke. Choices B, C, and D are incorrect because hypotension, hyperglycemia, and edema are not typically associated with epoetin alfa therapy in clients with chronic renal failure.
3. To reduce the risk of pulmonary complications for a client with ALS, which intervention should the nurse implement?
- A. Perform chest physiotherapy
- B. Teach the client breathing exercises
- C. Initiate passive range of motion exercises
- D. Establish a regular bladder routine
Correct answer: A
Rationale: Performing chest physiotherapy is the most appropriate intervention to reduce the risk of pulmonary complications in clients with ALS. Chest physiotherapy helps mobilize and clear respiratory secretions, improving lung function and reducing the risk of complications such as pneumonia. Teaching breathing exercises (Choice B) may be beneficial for some clients, but chest physiotherapy is more specifically targeted at managing pulmonary issues in ALS. Initiating passive range of motion exercises (Choice C) and establishing a regular bladder routine (Choice D) are important interventions in ALS care but are not directly related to reducing the risk of pulmonary complications.
4. 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.
5. A client has the following arterial blood gas (ABG) results: pH 7.51, PCO2 31 mm Hg, PO2 94 mm Hg, HCO3 24 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: D
Rationale: The ABG results show a pH above the normal range (7.35-7.45) and a decreased PCO2, indicating respiratory alkalosis. In respiratory alkalosis, the pH is increased and the PCO2 is decreased. Metabolic acidosis (choice A) would present with a low pH and low HCO3 levels. Metabolic alkalosis (choice B) would show an increased pH and HCO3 levels. Respiratory acidosis (choice C) would have a low pH and an increased PCO2.
