1. When a client taking warfarin sodium (Coumadin) is prescribed ciprofloxacin (Cipro), the nurse should closely monitor the client for which potential effect of this drug interaction?
- A. Increased risk of bleeding
- B. Decreased warfarin effectiveness
- C. Increased risk of thrombosis
- D. Decreased ciprofloxacin effectiveness
Correct answer: A
Rationale: When ciprofloxacin (Cipro) is given with warfarin sodium (Coumadin), it can potentiate the effects of warfarin, leading to an increased risk of bleeding. Therefore, the nurse should closely monitor the client's INR levels and watch for signs of bleeding such as bruising, petechiae, or black tarry stools.
2. A female client experiences a sudden loss of consciousness and is taken to the emergency department. Initial assessment indicates her blood glucose level is critically low. Once stabilized, she reports being treated for anorexia nervosa. What intervention is most important for the nurse to include in the client’s discharge plan?
- A. Encourage a high-protein, low-carbohydrate diet.
- B. Encourage her to join a group focusing on self-esteem.
- C. Schedule an outpatient psychosocial assessment.
- D. Teach relaxation techniques to manage stress.
Correct answer: B
Rationale: Joining a group that focuses on self-esteem is the most important intervention for the nurse to include in the client's discharge plan. This can help the client address underlying emotional issues related to her anorexia nervosa and improve her mental health. Choice A is incorrect because a high-protein, low-carbohydrate diet may not address the psychological factors contributing to anorexia nervosa. Choice C is incorrect as scheduling an outpatient psychosocial assessment is important but not the most crucial intervention for discharge planning in this case. Choice D is also not the priority as teaching relaxation techniques, although beneficial, may not directly address the self-esteem and emotional issues that need to be tackled in this situation.
3. A client is admitted for cellulitis surrounding an insect bite on the lower right arm, and intravenous (IV) antibiotic therapy is prescribed. Which action should the nurse implement before performing venipuncture?
- A. Lower the right arm below the level of the heart.
- B. Elevate the right arm on a pillow.
- C. Apply a tourniquet above the insertion site.
- D. Apply a warm compress to the insertion site.
Correct answer: A
Rationale: Before performing venipuncture for IV therapy, the nurse should lower the right arm below the level of the heart. Lowering the arm helps dilate the veins, making it easier to locate and access a suitable vein for the procedure. Elevating the arm on a pillow, applying a tourniquet above the insertion site, or applying a warm compress to the insertion site are not appropriate actions before venipuncture as they can affect the venous blood flow and make the procedure more challenging.
4. A healthcare professional is reviewing the results of renal function testing in a client with renal calculi. Which finding indicates to the healthcare professional that the client’s blood urea nitrogen (BUN) level is within the normal range?
- A. 2 mg/dL
- B. 18 mg/dL
- C. 25 mg/dL
- D. 35 mg/dL
Correct answer: B
Rationale: The normal BUN ranges from 5 to 20 mg/dL. A BUN level of 18 mg/dL falls within this normal range. Values of 25 and 35 mg/dL are elevated, suggesting potential renal insufficiency. Choice A (2 mg/dL) is abnormally low and not indicative of a normal BUN level.
5. A male client with impaired renal function who takes ibuprofen daily for chronic arthritis is showing signs of gastrointestinal (GI) bleeding. After administering IV fluids and a blood transfusion, his blood pressure is 100/70 mm Hg, and his renal output is 20 ml/hour. Which intervention should the nurse include in his care plan?
- A. Maintain the client NPO during the diuresis phase.
- B. Evaluate daily serial renal laboratory studies for progressive elevations.
- C. Observe the urine character for sedimentation and cloudy appearance.
- D. Monitor for the onset of polyuria greater than 150 ml/hour.
Correct answer: B
Rationale: In this scenario, the correct intervention for the nurse to include in the care plan is to evaluate daily serial renal laboratory studies for progressive elevations. This is crucial in monitoring renal function and detecting any worsening renal impairment. Option A is not directly related to managing renal function in this case. Option C focuses more on urinary characteristics rather than renal function monitoring. Option D addresses polyuria, which is an excessive urine output, but it does not specifically address the need for evaluating renal laboratory studies for progressive elevations.
