1. A client with obsessive-compulsive disorder (OCD) spends several hours a day washing his hands. What is the best nursing intervention?
- A. Restrict the client's access to soap and water.
- B. Encourage the client to discuss their compulsions.
- C. Allow the client to continue the behavior until ready to stop.
- D. Schedule activities that distract the client from hand-washing.
Correct answer: B
Rationale: Encouraging the client to discuss their compulsions is the best nursing intervention when caring for a client with OCD who spends excessive time on hand-washing. This approach can help the client identify underlying anxieties and triggers associated with the compulsive behavior. Restricting access to soap and water (Choice A) can lead to increased anxiety and worsen the obsession. Allowing the client to continue the behavior (Choice C) can perpetuate the compulsive cycle. Scheduling distracting activities (Choice D) may provide temporary relief but does not address the root cause of the behavior.
2. A nurse is preparing an infusion for a client who was hospitalized with deep-vein thrombosis. The orders read: 25,000 units of heparin in 250 mL of 0.9% sodium chloride to infuse at 800 units/hr. At what rate should the nurse set the infusion pump?
- A. 8 mL/hr
- B. 10 mL/hr
- C. 12 mL/hr
- D. 15 mL/hr
Correct answer: A
Rationale: To calculate the infusion rate, use the formula: (Desired units/hr / Total units) × Volume. In this case, it would be (800 units/hr / 25,000 units) × 250 mL = 8 mL/hr. Therefore, the nurse should set the infusion pump at 8 mL/hr. Choice B, 10 mL/hr, is incorrect because it does not match the calculated rate. Choices C and D, 12 mL/hr and 15 mL/hr respectively, are also incorrect as they do not align with the correct calculation based on the provided data.
3. An infant with hypertrophic pyloric stenosis (HPS) is admitted to the pediatric unit. What does the nurse expect when palpating the infant’s abdomen?
- A. A distended colon
- B. Marked tenderness around the umbilicus
- C. An olive-sized mass in the right upper quadrant
- D. Rhythmic peristaltic waves in the lower abdomen
Correct answer: C
Rationale: When palpating the abdomen of an infant with hypertrophic pyloric stenosis (HPS), the nurse would expect to feel an olive-sized mass in the right upper quadrant. This finding is characteristic of HPS due to the hypertrophied pylorus muscle. Choices A, B, and D are incorrect. A distended colon is not typically associated with HPS. Marked tenderness around the umbilicus is not a specific finding of HPS. Rhythmic peristaltic waves in the lower abdomen are not expected in HPS, as the condition primarily affects the pylorus region of the stomach.
4. A pre-term baby develops nasal flaring, cyanosis, and diminished breath sounds on one side. The provider's diagnosis is spontaneous pneumothorax. Which procedure should the nurse prepare for first?
- A. Cardiopulmonary resuscitation
- B. Insertion of a chest tube
- C. Oxygen therapy
- D. Assisted ventilation
Correct answer: B
Rationale: The correct answer is B: Insertion of a chest tube. In a case of spontaneous pneumothorax, the primary intervention is to insert a chest tube. This procedure allows the trapped air to escape from the pleural space, relieving pressure and enabling the lung to re-expand. Choices A, C, and D are not the initial interventions for spontaneous pneumothorax. Cardiopulmonary resuscitation is indicated for cardiac arrest, oxygen therapy may provide supportive care but does not address the underlying issue of trapped air in the pleural space, and assisted ventilation may be needed later but is not the first-line treatment for a pneumothorax.
5. During a blood transfusion, which observation indicates that the client is experiencing a transfusion reaction?
- A. The client reports feeling warm and flushed.
- B. The client develops a rash on the chest and back.
- C. The client experiences chills and a fever.
- D. The client complains of back pain and shortness of breath.
Correct answer: D
Rationale: Complaints of back pain and shortness of breath are classic signs of a transfusion reaction, specifically indicating a hemolytic reaction. This reaction can lead to the release of hemoglobin into the bloodstream, causing back pain and shortness of breath due to clot formation in the blood vessels, leading to decreased oxygen delivery. Warmth, flushing, rash, chills, and fever are more commonly associated with allergic reactions or febrile non-hemolytic reactions during transfusions. Therefore, options A, B, and C are incorrect in this context.
