Nursing Elites

1. A client with acute kidney injury (AKI) weighing 50kg and having a potassium level of 6.7mEq/L (6.7mmol/L) is admitted to the hospital. Which prescribed medication should the nurse administer first?

• A. Calcium acetate, one tablet by mouth
• B. Sodium polystyrene sulfonate, 15 grams by mouth
• C. Epoetin Alfa, recombinant, 2,500 units subcutaneously
• D. Sevelamer, one tablet by mouth

Correct answer: B

Rationale: In a client with acute kidney injury (AKI) and hyperkalemia, the priority intervention is to lower the potassium level swiftly. Sodium polystyrene sulfonate is a medication used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, reducing the overall potassium levels. Calcium acetate, epoetin alfa, and sevelamer are not indicated for the immediate reduction of potassium levels in hyperkalemia. Calcium acetate is used to control phosphate levels, epoetin alfa is a medication to treat anemia by stimulating red blood cell production, and sevelamer is a phosphate binder used in chronic kidney disease to reduce phosphate levels.

2. A client has been scheduled for magnetic resonance imaging (MRI). For which of the following conditions, a contraindication to MRI, does the nurse check the client’s medical history?

• A. Pancreatitis
• B. Pacemaker insertion
• C. Type 1 diabetes mellitus
• D. Chronic airway limitation

Correct answer: B

Rationale: The correct answer is B: Pacemaker insertion. Patients with metal devices or implants are contraindicated for MRI. These include pacemakers, orthopedic hardware, artificial heart valves, aneurysm clips, and intrauterine devices. These metal objects can be affected by the strong magnetic field of the MRI, leading to serious risks for the patient. Pancreatitis (choice A), Type 1 diabetes mellitus (choice C), and chronic airway limitation (choice D) are not contraindications to MRI based on the presence of metal objects. Therefore, the nurse should be particularly concerned about pacemaker insertion when reviewing the client's medical history prior to an MRI.

3. During an interview with a client planning elective surgery, the client asks the nurse, 'What is the advantage of having a preferred provider organization insurance plan?' Which response is best for the nurse to provide?

• A. Neither plan allows the selection of healthcare providers or hospitals.
• B. There are fewer healthcare providers to choose from than in an HMO plan.
• C. An individual may select healthcare providers from outside of the PPO network.
• D. An individual can become a member of a PPO without belonging to a group.

Correct answer: C

Rationale: The best response for the nurse to provide is option C, as it highlights a key advantage of a preferred provider organization (PPO) insurance plan. By stating that an individual may select healthcare providers from outside of the PPO network, the nurse emphasizes the flexibility and freedom of choice that PPO plans offer. This feature allows individuals to seek care from providers who are not part of the PPO network, albeit at a higher cost. Option A is incorrect because both PPO and HMO plans allow the selection of healthcare providers, although with different restrictions. Option B is incorrect as PPO plans typically offer a larger selection of healthcare providers compared to HMO plans. Option D is incorrect as membership in a PPO usually requires affiliation with a group, such as through employment or membership in an organization.

4. Which of the following is a sign of hypocalcemia?

• A. Hyperactive reflexes.
• B. Depressed reflexes.
• C. Muscle cramps.
• D. Seizures.

Correct answer: A

Rationale: Hyperactive reflexes are a classic sign of hypocalcemia. Hypocalcemia leads to increased neuromuscular excitability, resulting in hyperactive reflexes. Depressed reflexes (Choice B) are not typically associated with hypocalcemia. Muscle cramps (Choice C) can be seen in hypocalcemia due to muscle irritability but are not a specific sign. Seizures (Choice D) can occur in severe cases of hypocalcemia but are not as common as hyperactive reflexes.

5. An overweight client taking warfarin (Coumadin) has dry skin due to decreased arterial blood flow. What should the nurse instruct the client to do? Select all that apply.

• A. Apply lanolin or petroleum jelly to intact skin.
• B. Follow a reduced-calorie, reduced-fat diet.
• C. Inspect the involved areas daily for new ulcerations.
• D. Instruct the client to limit activities of daily living (ADLs).

Correct answer: A

Rationale: To address dry skin and prevent chronic ulcers and infections in an overweight client on warfarin with decreased arterial blood flow, the nurse should instruct the client to apply lanolin or petroleum jelly to intact skin. This helps maintain skin integrity and moisture. Following a reduced-calorie, reduced-fat diet (Choice B) may be beneficial for weight management but is not directly related to skin care. Inspecting involved areas daily for new ulcerations (Choice C) is important for skin assessment and early intervention but does not specifically address dry skin. Instructing the client to limit activities of daily living (ADLs) (Choice D) is not necessary for addressing dry skin; in fact, promoting mobility and circulation through appropriate activities is crucial.
