1. A child is hospitalized with a diagnosis of lead poisoning. The healthcare provider assisting in caring for the child would prepare to assist in administering which of the following medications?
- A. Activated charcoal
- B. Sodium bicarbonate
- C. Syrup of ipecac
- D. Dimercaprol (BAL in Oil)
Correct answer: D
Rationale: Dimercaprol (BAL in Oil) is a chelating agent indicated for lead poisoning. It works by binding to lead and facilitating its removal from the body. Activated charcoal is used for certain types of poisoning by adsorbing toxins, while sodium bicarbonate can be used to treat acidosis. Syrup of ipecac is no longer recommended for poison treatment due to potential risks.
2. Before administering furosemide (Lasix) to a client with heart failure, what is the most important laboratory test result for the nurse to check?
- A. Potassium level
- B. Creatinine level
- C. Cholesterol level
- D. Blood urea nitrogen
Correct answer: A
Rationale: The correct answer is to check the potassium level before administering furosemide (Lasix) to a client with heart failure. Furosemide is a loop diuretic that can cause hypokalemia, so it is crucial to assess the potassium level to prevent complications like cardiac arrhythmias associated with low potassium levels.
3. The client with ovarian cancer is being treated with vincristine (Oncovin). The nurse monitors the client, knowing that which of the following indicates a side effect specific to this medication?
- A. Diarrhea
- B. Hair loss
- C. Chest pain
- D. Numbness and tingling in the fingers and toes
Correct answer: D
Rationale: The correct answer is D: Numbness and tingling in the fingers and toes. Vincristine is known to cause peripheral neuropathy as a side effect, resulting in numbness and tingling in the fingers and toes. Diarrhea, hair loss, and chest pain are not typically associated with vincristine use.
4. A client is prescribed alendronate (Fosamax) for the treatment of osteoporosis. Which instruction should the nurse provide to the client?
- A. Take the medication at bedtime.
- B. Take the medication with a full glass of water.
- C. Lie down for 30 minutes after taking the medication.
- D. Take the medication with food to avoid gastrointestinal upset.
Correct answer: B
Rationale: The correct instruction for a client prescribed alendronate (Fosamax) for osteoporosis is to take the medication with a full glass of water first thing in the morning. It should be taken at least 30 minutes before any food, beverage, or other medication. The client should also remain upright for at least 30 minutes after taking the medication to prevent esophageal irritation. Taking alendronate at bedtime or with food is not recommended as it may reduce its absorption and effectiveness.
5. A healthcare professional prepares to administer sodium polystyrene sulfonate (Kayexalate) to a client. Before administering the medication, the professional reviews the action of the medication and understands that it:
- A. Releases bicarbonate in exchange for primarily sodium ions
- B. Releases sodium ions in exchange for primarily potassium ions
- C. Releases potassium ions in exchange for primarily sodium ions
- D. Releases sodium ions in exchange for primarily bicarbonate ions
Correct answer: B
Rationale: Sodium polystyrene sulfonate, such as Kayexalate, is a cation exchange resin that functions by releasing sodium ions in exchange for primarily potassium ions. This medication is commonly used to treat hyperkalemia, a condition characterized by elevated levels of potassium in the blood.
