Nursing Elites

1. A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Platelet count

Correct answer: C

Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.

2. A client in labor is experiencing late decelerations in fetal heart rate. What intervention should the nurse perform first?

• A. Reposition the client onto her left side.
• B. Apply oxygen via nasal cannula.
• C. Prepare for an emergency cesarean section.
• D. Increase IV fluid administration to improve perfusion.

Correct answer: A

Rationale: Late decelerations indicate fetal distress due to compromised placental perfusion. Repositioning the client onto her left side is the priority intervention as it can increase blood flow to the placenta, improving fetal oxygenation. Applying oxygen via nasal cannula (choice B) can be the next step after repositioning if late decelerations persist. Emergency cesarean section (choice C) is not the initial action for late decelerations unless other interventions are ineffective. Increasing IV fluid administration (choice D) is not the first-line intervention for late decelerations; repositioning takes precedence to address the underlying cause.

3. 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.

4. A client with chronic obstructive pulmonary disease (COPD) is experiencing difficulty breathing. What is the nurse's priority intervention?

• A. Administer a bronchodilator via nebulizer.
• B. Increase the client's oxygen flow rate.
• C. Elevate the head of the bed.
• D. Reposition the client to a side-lying position.

Correct answer: B

Rationale: In clients with COPD experiencing difficulty breathing, increasing the client's oxygen flow rate is the priority intervention. This action helps to improve oxygenation and relieve shortness of breath. While bronchodilators and other medications may be necessary, providing immediate oxygen support is crucial. Elevating the head of the bed and repositioning the client can assist with breathing comfort but do not address the immediate need for improved oxygenation in COPD exacerbation.

5. A client with type 1 diabetes is admitted to the emergency room with abdominal pain, polyuria, and confusion. What should the nurse implement first?

• A. Administer intravenous insulin.
• B. Start an intravenous fluid bolus.
• C. Obtain a blood glucose level.
• D. Administer an antiemetic.

Correct answer: B

Rationale: In this scenario, the nurse should first start an intravenous fluid bolus. This intervention is crucial in addressing severe dehydration associated with diabetic ketoacidosis, a life-threatening complication of type 1 diabetes. Administering intravenous insulin (Choice A) is important but should follow fluid resuscitation. Obtaining a blood glucose level (Choice C) is necessary but not as urgent as addressing the dehydration. Administering an antiemetic (Choice D) is not the priority in this situation.
