1. The client with a gastric ulcer has a prescription for sucralfate (Carafate), 1 g by mouth four times daily. The nurse schedules the medication for which times?
- A. With meals and at bedtime
- B. Every 6 hours around the clock
- C. One hour after meals and at bedtime
- D. One hour before meals and at bedtime
Correct answer: D
Rationale: Sucralfate is a gastric protectant that forms a protective coating over the ulcer. Administering sucralfate 1 hour before meals and at bedtime is important to create a barrier that protects the ulcer from gastric acid and mechanical irritation. This timing allows sucralfate to effectively coat the ulcer site and provide the desired therapeutic effect, enhancing its efficacy in promoting ulcer healing and symptom relief.
2. A teenager who has lost 20 pounds in the last three months is admitted to the hospital with hypotension and tachycardia. The client reports irregular menses and hair loss. Which intervention is most important for the nurse to include in the client plan of care?
- A. Implement behavior modification therapy.
- B. Initiate caloric and nutritional therapy.
- C. Evaluate the client for low self-esteem.
- D. Record daily weights and graph trends.
Correct answer: B
Rationale: Initiating caloric and nutritional therapy is the most important intervention for this client due to the significant weight loss and presenting symptoms of hypotension, tachycardia, irregular menses, and hair loss. This intervention aims to address the physical effects of malnutrition and support the client's overall health. Behavior modification therapy (Choice A) may be beneficial in the long term to address underlying issues, but addressing the immediate nutritional needs is a priority. Evaluating the client for low self-esteem (Choice C) is important for holistic care but addressing the physical health concerns takes precedence. Recording daily weights and graphing trends (Choice D) is essential for monitoring progress but does not address the urgent need for nutritional support in this acute situation.
3. A client is vomiting. For which acid-base imbalance does the nurse assess the client?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: B
Rationale: In a client who is vomiting, the loss of gastric fluid containing hydrochloric acid can lead to metabolic alkalosis. Metabolic alkalosis is caused by the loss of acids such as hydrochloric acid from the body. Therefore, in this scenario, the nurse should assess the client for metabolic alkalosis. Choices A, C, and D are incorrect because vomiting does not typically lead to metabolic acidosis, respiratory acidosis, or respiratory alkalosis.
4. A client with chronic kidney disease (CKD) is scheduled for a hemodialysis session. Which laboratory value should the nurse report to the healthcare provider before the procedure?
- A. Serum potassium of 5.5 mEq/L
- B. Blood urea nitrogen (BUN) of 40 mg/dl
- C. Serum potassium of 6.0 mEq/L
- D. Serum creatinine of 2.5 mg/dl
Correct answer: C
Rationale: A serum potassium level of 6.0 mEq/L is dangerously high for a client with chronic kidney disease (CKD) scheduled for hemodialysis. High potassium levels can lead to cardiac complications such as arrhythmias. Therefore, it is crucial to report this value to the healthcare provider before the procedure to prevent any potential serious complications. Choices A, B, and D are not as critical in the context of preparing for a hemodialysis session. Serum potassium levels above 6.0 mEq/L require immediate attention to ensure patient safety.
5. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin. Which laboratory value should the nurse monitor to assess the therapeutic effect of this medication?
- A. Platelet count
- B. Prothrombin time (PT)
- C. White blood cell count
- D. Hemoglobin level
Correct answer: B
Rationale: Prothrombin time (PT) is the correct laboratory value to monitor to assess the therapeutic effect of warfarin. Warfarin works by inhibiting clotting factors, and PT measures the time it takes for blood to clot. Monitoring PT helps ensure that the medication is working effectively to prevent clot formation without causing excessive bleeding. Platelet count (Choice A) is not specific to warfarin therapy and assesses the number of platelets in the blood. White blood cell count (Choice C) and hemoglobin level (Choice D) are not directly related to monitoring the therapeutic effect of warfarin.
