Nursing Elites

1. A nurse is caring for a client who is postoperative following a total knee arthroplasty. Which of the following actions should the nurse take?

• A. Place a pillow under the client's knees
• B. Keep the client's legs elevated
• C. Flex the client's knee every 2 hours
• D. Apply heat to the operative knee

Correct answer: B

Rationale: Keeping the client's legs elevated is the appropriate action to prevent venous thromboembolism following a total knee arthroplasty. Elevating the legs helps promote circulation and reduce the risk of blood clots. Placing a pillow under the client's knees may provide comfort but does not address the specific postoperative complication. Flexing the client's knee every 2 hours may be contraindicated as excessive movement can disrupt the surgical site. Applying heat to the operative knee is not recommended immediately postoperatively as it can increase swelling and discomfort.

2. A client with a history of angina reports substernal chest pain that radiates to the left arm. Which of the following actions should the nurse take first?

• A. Administer nitroglycerin sublingually.
• B. Administer 2L of oxygen via nasal cannula.
• C. Administer aspirin 325 mg orally.
• D. Obtain a 12-lead ECG.

Correct answer: D

Rationale: In a client with a history of angina experiencing chest pain radiating to the left arm, obtaining a 12-lead ECG is the priority action to assess for myocardial infarction. An ECG helps in diagnosing and evaluating the extent of cardiac ischemia or infarction. Administering nitroglycerin, oxygen, or aspirin can follow once the ECG has been performed to confirm the diagnosis and guide further interventions. Administering nitroglycerin sublingually is often appropriate for angina but should not precede the ECG in this urgent scenario. Oxygen therapy and aspirin administration are important interventions but obtaining the ECG takes precedence in assessing for acute cardiac events.

3. A client has a new prescription for metformin. Which of the following client statements indicates an understanding of the teaching?

• A. ''I will take this medication at bedtime to avoid nausea.''
• B. ''I should take this medication with a full glass of water in the morning.''
• C. ''I should avoid eating foods that contain iodine.''
• D. ''I should take this medication with food to improve absorption.''

Correct answer: B

Rationale: The correct answer is B. Metformin should be taken with a full glass of water in the morning to improve absorption and prevent gastrointestinal upset. Choice A is incorrect because metformin is not typically taken at bedtime. Choice C is unrelated to metformin therapy. Choice D is incorrect because metformin is actually better absorbed when taken with or after meals.

4. A healthcare provider is reviewing the medical record of a client who has schizophrenia and is taking clozapine. Which finding should the healthcare provider identify as a contraindication to the administration of clozapine?

• A. Heart rate 58/min.
• B. Fasting blood glucose 100 mg/dL.
• C. Hgb 14 g/dL.
• D. WBC count 2,900/mm3.

Correct answer: D

Rationale: The correct answer is D: a low WBC count. Clozapine can suppress bone marrow function, leading to a decreased white blood cell count. This condition, known as agranulocytosis, increases the risk of severe infections. Monitoring WBC counts is essential during clozapine therapy. Choices A, B, and C are within normal ranges and are not contraindications for administering clozapine.

5. A nurse is assessing a client who is receiving total parenteral nutrition (TPN). Which of the following findings should the nurse report to the provider?

• A. Blood glucose of 110 mg/dL.
• B. Weight loss of 0.5 kg (1.1 lb) in 24 hours.
• C. WBC count of 6,500/mm3.
• D. Temperature of 37.3°C (99.1°F).

Correct answer: B

Rationale: A weight loss of 0.5 kg (1.1 lb) in 24 hours may indicate dehydration or malnutrition, which are critical concerns for a client receiving total parenteral nutrition (TPN). Therefore, the nurse should report this finding to the provider. Elevated blood glucose levels (Choice A) can be managed by adjusting TPN components, WBC count (Choice C) and a slightly elevated temperature (Choice D) are not directly related to TPN administration and may not require immediate intervention.
