Nursing Elites

1. The nurse is teaching a client about postoperative care following a total knee arthroplasty. What instruction should the nurse prioritize?

• A. Begin ambulation as soon as possible.
• B. Use continuous passive motion therapy to maintain joint mobility.
• C. Avoid putting weight on the affected leg.
• D. Apply ice packs to reduce pain and swelling.

Correct answer: B

Rationale: The correct answer is B: 'Use continuous passive motion therapy to maintain joint mobility.' Continuous passive motion therapy is crucial in postoperative care following a total knee arthroplasty as it helps prevent stiffness and maintain joint mobility. Ambulation is important but should be guided and not immediate. Avoiding putting weight on the affected leg is also essential initially to prevent complications. Applying ice packs can help reduce pain and swelling, but it is not the priority instruction for maintaining joint mobility and preventing stiffness.

2. A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

3. At 0600 while admitting a woman for a scheduled repeat cesarean section, the client tells the nurse that she drank a cup of coffee at 0400 because she wanted to avoid getting a headache. Which action should the nurse take first?

• A. Cancel the surgery
• B. Inform the anesthesia care provider
• C. Ask the client if she has had any other liquids
• D. Proceed with routine preparations

Correct answer: B

Rationale: Drinking liquids before surgery can increase the risk of aspiration during anesthesia. Therefore, the anesthesia care provider must be informed immediately to determine how to proceed, as this could delay or alter the surgical plan. Canceling the surgery without consulting the anesthesia care provider would be premature and could potentially lead to unnecessary actions. Asking the client if she has had any other liquids is important but not the first priority. Proceeding with routine preparations without addressing the potential issue of ingesting liquids before surgery could compromise the client's safety.

4. The nurse is conducting intake interviews of children at a city clinic. Which child is most susceptible to contracting lead poisoning?

• A. An 8-year-old living in a housing project.
• B. A 2-year-old playing on aging playground equipment.
• C. An adolescent working in a paint factory.
• D. A 10-year-old with Type 1 diabetes.

Correct answer: B

Rationale: The correct answer is B. Young children, like the 2-year-old playing on aging playground equipment, are more susceptible to lead poisoning from environmental sources due to their behaviors like hand-to-mouth contact and exploratory behaviors. Choices A, C, and D are less likely to be at high risk for lead poisoning compared to young children due to differences in exposure levels and behaviors related to potential sources of lead contamination.

5. An older client with SIRS has a temperature of 101.8°F, a heart rate of 110 beats per minute, and a respiratory rate of 24 breaths per minute. Which additional finding is most important to report to the healthcare provider?

• A. Serum creatinine of 2.0 mg/dL
• B. Elevated WBC count
• C. Blood pressure of 100/60 mmHg
• D. Oxygen saturation of 95%

Correct answer: A

Rationale: A serum creatinine level of 2.0 mg/dL indicates possible acute kidney injury, which can occur during severe systemic inflammatory response syndrome (SIRS). Reporting this value promptly allows for interventions to prevent further renal damage. Elevated WBC count (choice B) is a common feature of SIRS and may not be as urgently indicative of immediate organ damage as high creatinine levels. A blood pressure of 100/60 mmHg (choice C) is relatively low but may be a typical finding in SIRS; however, renal function is critical in this context. Oxygen saturation of 95% (choice D) is within normal limits and is not as concerning as a high creatinine level in this scenario.
