1. 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.
2. For the past 24 hours, an antidiarrheal agent, diphenoxylate, has been administered to a bedridden, older client with infectious gastroenteritis. Which finding requires the nurse to take further action?
- A. Tented skin turgor
- B. Decreased bowel sounds
- C. Persistent diarrhea
- D. Dehydration
Correct answer: A
Rationale: The correct answer is A. Tented skin turgor is a sign of dehydration, which can be exacerbated by the use of antidiarrheals in clients with gastroenteritis. In dehydration, the skin loses its elasticity and becomes less resilient when pinched. Therefore, the nurse should take immediate action upon noticing tented skin turgor to prevent further complications. Choices B, C, and D are incorrect because decreased bowel sounds, persistent diarrhea, and dehydration are expected findings in a client with gastroenteritis who has been administered an antidiarrheal agent.
3. A client receiving filgrastim (Neupogen) for neutropenia is learning about compromised host precautions. The selection of which lunch suggests the client has learned about necessary dietary changes?
- A. grilled chicken sandwich and skim milk
- B. roast beef, mashed potatoes, and green beans
- C. peanut butter sandwich, banana, and iced tea
- D. barbecue beef, baked beans, and cole slaw
Correct answer: B
Rationale: Roast beef, mashed potatoes, and green beans are suitable choices for clients with neutropenia because they are considered safe options that help avoid potential sources of infection. Grilled chicken, peanut butter, and barbecue beef may carry a higher risk of bacterial contamination, which could be harmful to a client with compromised immunity.
4. Isotretinoin is prescribed for a client with severe acne. Before the administration of this medication, the nurse anticipates that which laboratory test will be prescribed?
- A. Platelet count
- B. Triglyceride level
- C. Complete blood count
- D. White blood cell count
Correct answer: B
Rationale: Before administering Isotretinoin, it is important to check the client's triglyceride levels. Isotretinoin is known to elevate triglyceride levels, hence monitoring them before and periodically during treatment is essential to prevent potential adverse effects.
5. Which of the following describes the role of the nurse in advocating for a patient?
- A. The nurse ensures that the patient has all the information needed to make an informed decision about their care.
- B. The nurse advocates for the patient by communicating their needs and preferences to the healthcare team.
- C. The nurse advocates for the patient by ensuring that they receive the care they need and by protecting their rights.
- D. The nurse advocates for the patient by helping them navigate the healthcare system and access necessary resources.
Correct answer: C
Rationale: The correct answer is C. Nurses advocate for patients by ensuring that they receive the necessary care and by protecting their rights. This involves speaking up for patients, ensuring they are treated with respect, and helping them access appropriate healthcare services. Option A, providing information for informed decision-making, is an important aspect of nursing care but not the central role of advocacy. Option B, communicating patients' needs to the healthcare team, is essential but more focused on teamwork and collaboration. Option D, helping patients navigate the healthcare system and access resources, is valuable but not the primary definition of advocacy in nursing.
