1. A patient with a diagnosis of deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin therapy?
- A. Prothrombin time (PT)
- B. Partial thromboplastin time (PTT)
- C. Bleeding time
- D. Platelet count
Correct answer: B
Rationale: The correct answer is B: Partial thromboplastin time (PTT). Heparin affects the intrinsic pathway of the coagulation cascade, which is reflected by changes in the PTT. Monitoring the PTT helps ensure that the patient's blood is within the desired therapeutic range and prevents complications related to clotting or bleeding. Prothrombin time (PT) primarily assesses the extrinsic pathway and is not as sensitive to heparin therapy. Bleeding time and platelet count are not specific tests for monitoring the effectiveness of heparin therapy in DVT.
2. A client receiving total parenteral nutrition (TPN) through a central line suddenly develops dyspnea, chest pain, and a drop in blood pressure. What should the nurse do first?
- A. Stop the TPN infusion.
- B. Notify the healthcare provider.
- C. Place the client in Trendelenburg position.
- D. Administer oxygen at 2 liters/minute.
Correct answer: C
Rationale: Placing the client in Trendelenburg position should be the initial action as it can help manage a suspected air embolism, a potential complication of TPN administration. This position helps trap air in the apex of the atrium, reducing the risk of air reaching the pulmonary circulation and causing further harm. Once the client is in a safe position, further actions such as stopping the TPN infusion, notifying the healthcare provider, and administering oxygen can be taken as appropriate.
3. A client is scheduled for a colonoscopy. Which instruction should the nurse provide?
- A. Eat a light breakfast on the day of the procedure.
- B. You will need to drink a bowel preparation solution before the procedure.
- C. Avoid all liquids for 24 hours before the procedure.
- D. You can continue taking your blood thinners until the day of the procedure.
Correct answer: B
Rationale: The correct instruction for a client scheduled for a colonoscopy is to drink a bowel preparation solution before the procedure. This solution helps cleanse the colon, ensuring clear visualization during the colonoscopy procedure. Choice A is incorrect because a light breakfast is usually recommended the day before the procedure, not on the day of the colonoscopy. Choice C is incorrect as it is important to stay hydrated and follow specific instructions regarding liquid intake. Choice D is incorrect as blood thinners may need to be adjusted or stopped before the colonoscopy to reduce the risk of bleeding during the procedure.
4. The client is receiving intravenous (IV) morphine for pain control. Which assessment finding requires the most immediate intervention?
- A. Drowsiness.
- B. Itching.
- C. Nausea.
- D. Respiratory rate of 8 breaths per minute.
Correct answer: D
Rationale: A respiratory rate of 8 breaths per minute indicates severe respiratory depression, a life-threatening side effect of opioid therapy. Immediate intervention is crucial to prevent respiratory failure. Monitoring and managing respiratory status are critical in clients receiving opioids to prevent adverse events. Drowsiness, itching, and nausea are common side effects of morphine but are not as immediately life-threatening as severe respiratory depression.
5. The healthcare provider is assessing a client with Raynaud's phenomenon. Which finding should the healthcare provider expect?
- A. Thickened and hardened skin.
- B. Painless ulcers on the fingertips.
- C. Episodes of cyanosis and pallor in the fingers.
- D. Red, scaly patches on the hands.
Correct answer: C
Rationale: Raynaud's phenomenon is characterized by vasospasm, leading to episodes of cyanosis (bluish discoloration) and pallor (pale color) in the fingers or toes, often triggered by cold temperatures or stress. This occurs due to the reduced blood flow during vasospastic episodes, causing the discoloration. Choices A, B, and D are incorrect findings associated with other conditions and are not typical of Raynaud's phenomenon.
