Nursing Elites

1. A client with deep vein thrombosis (DVT) is prescribed heparin. What lab value should the nurse monitor to assess the effectiveness of the therapy?

• A. Prothrombin time (PT).
• B. Partial thromboplastin time (PTT).
• C. International Normalized Ratio (INR).
• D. Hemoglobin and hematocrit.

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). PTT is the lab value used to monitor the effectiveness of heparin therapy in clients with DVT. It measures the intrinsic pathway of coagulation and is prolonged by heparin therapy. Prothrombin time (PT) and International Normalized Ratio (INR) are primarily used to monitor warfarin therapy, not heparin. Checking hemoglobin and hematocrit levels is important but does not directly assess the effectiveness of heparin therapy in DVT.

2. A child newly diagnosed with sickle cell anemia (SCA) is being discharged from the hospital. Which information is most important for the nurse to provide the parents prior to discharge?

• A. Nutritional guidelines to support blood health
• B. Signs of infection to monitor for
• C. When to give pain medication
• D. Instructions about how much fluid the child should drink daily

Correct answer: D

Rationale: Proper hydration is crucial in managing sickle cell anemia (SCA) as it helps prevent sickling of red blood cells and reduces blood viscosity, which can lead to painful crises. Ensuring the child drinks enough fluids is essential to maintain adequate hydration levels and reduce the risk of complications. While nutritional guidelines and recognizing signs of infection are important aspects of care, maintaining proper hydration is the most immediate and critical factor in managing SCA and preventing crises.

3. The nurse is caring for a client with an acute myocardial infarction. Which symptom requires immediate intervention?

• A. Dizziness
• B. Shortness of breath
• C. Severe chest pain
• D. Nausea and vomiting

Correct answer: C

Rationale: Severe chest pain is the hallmark symptom of an acute myocardial infarction (heart attack) and requires immediate intervention to prevent further damage to the heart muscle. Chest pain in this context is often described as crushing, pressure, tightness, or heaviness. It can radiate to the arms, neck, jaw, back, or upper abdomen. Other symptoms like dizziness, shortness of breath, nausea, and vomiting may also occur in acute myocardial infarction, but chest pain is the most critical sign requiring prompt action as it signifies inadequate blood flow to the heart muscle. Shortness of breath may indicate heart failure, while nausea and vomiting can be associated with the sympathetic response to myocardial infarction. Dizziness could result from decreased cardiac output but is not as specific to myocardial infarction as severe chest pain.

4. The nurse is reviewing the laboratory results of a client with chronic kidney disease. The client's serum calcium level is 7.5 mg/dL. Which condition should the nurse suspect?

• A. Hypercalcemia
• B. Hyperkalemia
• C. Hyponatremia
• D. Hypocalcemia

Correct answer: D

Rationale: A serum calcium level of 7.5 mg/dL is indicative of hypocalcemia, a common complication in clients with chronic kidney disease due to impaired calcium absorption and metabolism. Hypercalcemia (Choice A) is the opposite of the condition presented in the question and is characterized by elevated serum calcium levels. Hyperkalemia (Choice B) is an increased potassium level, not related to the client's serum calcium level. Hyponatremia (Choice C) is a decreased sodium level and is also not related to the client's serum calcium level.

5. A client with hypertension has been prescribed a calcium channel blocker. What should the nurse include in the client's teaching plan?

• A. Monitor heart rate regularly
• B. Avoid potassium-rich foods
• C. Increase fluid intake to avoid dehydration
• D. Take the medication with food

Correct answer: A

Rationale: Corrected Rationale: Calcium channel blockers can cause bradycardia, so it is important for the client to monitor their heart rate regularly. This helps detect any significant changes in heart rate that may require medical attention. Choice B is incorrect because there is no need to avoid potassium-rich foods with calcium channel blockers. Choice C is incorrect as increasing fluid intake is not specifically related to calcium channel blockers. Choice D is incorrect as calcium channel blockers are usually taken with or without food, depending on the specific medication, but not specifically on an empty stomach.
