ATI Medical Surgical Proctored Exam 2019 Quizlet
1. A client with a history of diabetes mellitus is admitted with a foot ulcer. The nurse should recognize that which intervention is most critical in promoting healing of the foot ulcer?
- A. Strict control of blood glucose levels.
- B. Regular dressing changes with sterile technique.
- C. Application of antibiotic ointment.
- D. Hydrotherapy treatment daily.
Correct answer: A
Rationale: In diabetic clients with foot ulcers, strict control of blood glucose levels is essential for promoting wound healing. High blood glucose levels can impair circulation and compromise the body's ability to fight infection, delaying the healing process. By maintaining optimal blood glucose levels, the client's overall health and wound healing potential are improved.
2. A client with hepatic encephalopathy is being treated with lactulose. What is an expected outcome of this treatment?
- A. Reduction in blood ammonia levels
- B. Improvement in liver enzyme levels
- C. Decrease in bilirubin levels
- D. Increase in urine output
Correct answer: A
Rationale: Lactulose is used to treat hepatic encephalopathy by reducing blood ammonia levels through promoting its excretion via the intestines. Elevated ammonia levels contribute to the development of encephalopathy symptoms, so by lowering them, the client's neurological status can improve.
3. A client with deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to assess the effectiveness of the therapy?
- A. Prothrombin time (PT)
- B. Platelet count
- C. Activated partial thromboplastin time (aPTT)
- D. International normalized ratio (INR)
Correct answer: C
Rationale: Activated partial thromboplastin time (aPTT) is the appropriate laboratory test to monitor the effectiveness of heparin therapy. Heparin works by prolonging the clotting time, which is reflected in the aPTT results. Monitoring aPTT helps ensure the patient is within the therapeutic range and not at risk of bleeding or clotting complications. Prothrombin time (PT) (Choice A) primarily measures the extrinsic pathway of coagulation and is used to monitor warfarin therapy, not heparin. Platelet count (Choice B) assesses the number of platelets present in the blood and is not specific to monitoring heparin therapy. International normalized ratio (INR) (Choice D) is used to monitor warfarin therapy, not heparin.
4. The healthcare provider formulates a nursing diagnosis of 'High risk for ineffective airway clearance' for a client with myasthenia gravis. What is the most likely cause for this nursing diagnosis?
- A. Pain during coughing.
- B. Diminished cough effort.
- C. Thick, dry secretions.
- D. Excessive inflammation.
Correct answer: B
Rationale: Clients with myasthenia gravis commonly experience muscle weakness, including in the muscles used for coughing. This diminished cough effort can lead to ineffective airway clearance, increasing the risk of respiratory complications. Therefore, the most likely cause for the nursing diagnosis 'High risk for ineffective airway clearance' in a client with myasthenia gravis is the diminished cough effort due to muscle weakness.
5. A 60-year-old man presents with fatigue, weight gain, and constipation. Laboratory tests reveal low TSH and high free T4 levels. What is the most likely diagnosis?
- A. Hypothyroidism
- B. Hyperthyroidism
- C. Thyroiditis
- D. Thyroid cancer
Correct answer: B
Rationale: The combination of low TSH and high free T4 levels is characteristic of hyperthyroidism, not hypothyroidism. Hyperthyroidism is associated with symptoms such as fatigue, weight loss, and diarrhea, contrasting with the typical presentation of hypothyroidism. Therefore, in this case, the most likely diagnosis is hyperthyroidism.
