1. A 56-year-old woman presents to discuss the results of her recent upper endoscopy. She was having some mild abdominal pain, so she underwent the procedure, which revealed an ulcer in the antrum of the stomach. Biopsy of the lesion revealed the presence of H. pylori. All of the following statements regarding her condition are correct except
- A. H. pylori has been associated with gastric MALT (mucosa-associated lymphoid tissue)
- B. Reinfection is rare despite adequate treatment
- C. Triple drug therapy has been shown to be more effective than dual drug therapy
- D. If her H. pylori IgG antibody titer was elevated prior to therapy, it can be used to monitor treatment efficacy
Correct answer: B
Rationale: H. pylori is associated with a majority of peptic ulcer disease cases and has links to gastric MALT and adenocarcinoma. Triple drug therapy is more effective than dual therapy. Reinfection after adequate treatment is rare. While urea breath testing is a better diagnostic tool, quantitative serology can monitor treatment efficacy. A 30% decrease in IgG titer should occur post-therapy, indicating effectiveness.
2. The nurse is caring for a client with a spinal cord injury. Which intervention should the nurse implement to prevent autonomic dysreflexia?
- A. Restrict the client's fluid intake.
- B. Keep the client's room warm.
- C. Ensure the client's bladder is emptied regularly.
- D. Limit the client's intake of high-fiber foods.
Correct answer: C
Rationale: To prevent autonomic dysreflexia in clients with spinal cord injuries, it is crucial to ensure the client's bladder is emptied regularly. Bladder distention is a common trigger for autonomic dysreflexia in these clients. Keeping the bladder empty helps prevent the complications associated with autonomic dysreflexia, such as dangerously high blood pressure. Choices A, B, and D are incorrect. Restricting fluid intake can lead to dehydration, keeping the room warm is not directly related to preventing autonomic dysreflexia, and limiting high-fiber foods is not a primary intervention for this condition.
3. A healthcare professional is assessing a client with severe dehydration. Which finding indicates a need for immediate intervention?
- A. Heart rate of 110 beats per minute.
- B. Blood pressure of 90/60 mm Hg.
- C. Urine output of 20 ml/hour.
- D. Dry mucous membranes.
Correct answer: C
Rationale: A urine output of 20 ml/hour indicates severe dehydration and impaired renal function. This finding suggests a critical state where the kidneys are conserving water, leading to reduced urine output. Immediate intervention is required to restore fluid balance and prevent further complications associated with severe dehydration. Choice A, a heart rate of 110 beats per minute, may indicate dehydration but is not as severe as the critically low urine output. Choice B, a blood pressure of 90/60 mm Hg, can be seen in dehydration but is not as concerning as the extremely low urine output. Choice D, dry mucous membranes, is a common sign of dehydration but does not require immediate intervention compared to the severely reduced urine output.
4. A 50-year-old man presents with fatigue, arthralgia, and darkening of the skin. Laboratory tests reveal elevated liver enzymes and high serum ferritin levels. What is the most likely diagnosis?
- A. Wilson's disease
- B. Hemochromatosis
- C. Alpha-1 antitrypsin deficiency
- D. Autoimmune hepatitis
Correct answer: B
Rationale: The symptoms of fatigue, arthralgia, and skin darkening, along with elevated liver enzymes and high serum ferritin levels, are characteristic of hemochromatosis, a condition characterized by iron overload. In hemochromatosis, excess iron is deposited in various organs, including the liver, leading to symptoms such as fatigue, joint pain, and skin pigmentation changes. The elevated liver enzymes and high serum ferritin levels seen in this patient further support the diagnosis of hemochromatosis.
5. 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.
