1. The client has reinforced instructions for taking cholestyramine (Questran). Which statement indicates a need for further instructions?
- A. I will continue taking vitamin supplements.
- B. This medication will help lower my cholesterol.
- C. This medication should only be taken with water.
- D. A high-fiber diet is important while taking this medication.
Correct answer: C
Rationale: The correct answer is C because cholestyramine should not only be taken with water. Flavored products or fruit juices can improve the taste. Choices A, B, and D are all correct statements. It is important for the client to continue taking vitamin supplements, understand that cholestyramine helps lower cholesterol, and maintain a high-fiber diet while taking this medication to enhance its effectiveness.
2. A 9-year-old is hospitalized for neutropenia and is placed in reverse isolation. The child asks the nurse, 'Why do you have to wear a gown and mask when you are in my room?' How should the nurse respond?
- A. To protect myself from your germs.
- B. To protect you because you can get an infection very easily.
- C. Until your white blood cell count increases.
- D. To keep others from getting your infection.
Correct answer: B
Rationale: Reverse isolation precautions protect the client from exposure to microorganisms from others.
3. The nurse is caring for a client who is 2 days post-op following an abdominal surgery. The client reports feeling something 'give way' in the incision site and there is a small amount of bowel protruding from the wound. What action should the nurse take first?
- A. Apply a sterile saline dressing to the wound
- B. Notify the healthcare provider
- C. Administer pain medication
- D. Cover the wound with an abdominal binder
Correct answer: A
Rationale: In this situation, the priority action for the nurse is to apply a sterile saline dressing to the wound. This helps prevent infection and keeps the wound moist, which is crucial in promoting healing and preventing further complications. Option B, notifying the healthcare provider, is important but should come after addressing the wound. Administering pain medication (Option C) may be necessary but is not the first action to take in this emergency situation. Covering the wound with an abdominal binder (Option D) is not appropriate and may cause further harm by applying pressure to the protruding bowel.
4. A 26-year-old, gravida 2, para 1 client is admitted to the hospital at 28 weeks gestation in preterm labor. She is given 3 doses of terbutaline sulfate (Brethine) 0.25 mg subcutaneously to stop her labor contractions. The LPN/LVN plans to monitor for which primary side effect of terbutaline sulfate?
- A. Drowsiness and bradycardia.
- B. Depressed reflexes and increased respirations.
- C. Tachycardia and a feeling of nervousness.
- D. A flushed, warm feeling and a dry mouth.
Correct answer: C
Rationale: The primary side effects of terbutaline sulfate are related to its beta-adrenergic effects. Tachycardia and nervousness are common side effects of terbutaline sulfate. Tachycardia is expected due to the drug's beta-agonist properties, while nervousness can result from the stimulation of beta-adrenergic receptors. It is crucial to monitor the client for these side effects to ensure early recognition and appropriate management.
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.
