Nursing Elites

1. A client with deep vein thrombosis (DVT) is prescribed heparin therapy. What laboratory value should the nurse monitor?

• A. Monitor the client’s liver function tests.
• B. Monitor the client’s prothrombin time (PT).
• C. Monitor the client’s partial thromboplastin time (PTT).
• D. Monitor the client’s red blood cell count.

Correct answer: C

Rationale: The correct answer is C: Monitor the client’s partial thromboplastin time (PTT). During heparin therapy for DVT, it is essential to monitor the PTT to assess the effectiveness of the medication in preventing clot formation. Monitoring the PTT helps ensure that the client is within the therapeutic range for anticoagulation. Choices A, B, and D are incorrect because liver function tests, prothrombin time (PT), and red blood cell count are not specifically monitored to assess the effectiveness of heparin therapy in preventing clot formation.

2. The nurse is administering an intradermal injection for a tuberculosis skin test. Which technique should the nurse use?

• A. Use a 25-gauge needle at a 90-degree angle
• B. Use a 27-gauge needle at a 15-degree angle
• C. Use a 22-gauge needle at a 45-degree angle
• D. Use a 20-gauge needle at a 90-degree angle

Correct answer: B

Rationale: An intradermal injection for a tuberculosis skin test should be administered using a 27-gauge needle at a 15-degree angle. This technique ensures that the medication is delivered into the dermis layer of the skin. Choice A is incorrect because a 25-gauge needle is too large for an intradermal injection. Choice C is incorrect as a 22-gauge needle is also too large and the angle is too steep for an intradermal injection. Choice D is incorrect as a 20-gauge needle is too large for an intradermal injection, and a 90-degree angle would not deliver the medication accurately into the dermis.

3. The nurse is caring for a 24-month-old toddler who has sensory sensitivity, difficulty engaging in social interactions, and has not yet spoken two-word phrases. Which assessment should the nurse administer?

• A. Peabody Picture Vocabulary Test
• B. The Modified Checklist for Autism in Toddlers (M-CHAT)
• C. Wechsler Preschool and Primary Scale of Intelligence
• D. Denver Developmental Screening Test

Correct answer: B

Rationale: The Modified Checklist for Autism in Toddlers (M-CHAT) is specifically designed to screen for autism spectrum disorders in young children. It is appropriate for this child, given the signs of social and communication delays. The Peabody Picture Vocabulary Test (Choice A) assesses receptive vocabulary and may not capture the social and communication aspects seen in autism. The Wechsler Preschool and Primary Scale of Intelligence (Choice C) measures cognitive ability and may not address the social and communication delays. The Denver Developmental Screening Test (Choice D) is a broad developmental assessment tool, but the M-CHAT is more specific to screening for autism in this case.

4. 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.

5. A nurse is caring for a client with a chest tube following lung surgery. What is the most important intervention to ensure the chest tube functions properly?

• A. Clamp the tube if there is excessive drainage
• B. Empty the drainage chamber every 2 hours
• C. Keep the drainage system below chest level
• D. Milk the tube to prevent clots from forming

Correct answer: C

Rationale: The correct answer is C. Keeping the chest tube drainage system below chest level ensures that gravity assists with drainage and prevents fluid or air from flowing back into the pleural space, which could compromise lung function. Clamping the tube if there is excessive drainage (choice A) is incorrect as it can lead to a buildup of pressure and compromise the drainage system. Emptying the drainage chamber every 2 hours (choice B) is important but not as crucial as maintaining the drainage system below chest level. Milking the tube to prevent clots from forming (choice D) is incorrect and could lead to complications such as tube occlusion or damage to the tissue.
