An emergency department nurse assesses a client with a history of urinary incontinence who presents with extreme dry mouth, constipation, and an inability to void. Which question should the nurse ask first?
- A. Are you drinking plenty of water?
- B. What medications are you taking?
- C. Have you tried laxatives or enemas?
- D. Has this type of thing ever happened before?
Correct Answer: B
Rationale: In this scenario, the client's symptoms of dry mouth, constipation, and inability to void are indicative of anticholinergic side effects, which can be caused by medications like propantheline (Pro-Banthine) commonly used to treat incontinence. The first question the nurse should ask is about the client's medications to determine if they are taking anticholinergic drugs. This information is crucial as it can help differentiate between a simple side effect or a potential overdose. Asking about water intake (Choice A) may be relevant later but is not the priority in this situation. Questioning about laxatives or enemas (Choice C) and past occurrences (Choice D) are not as pertinent initially as identifying the client's current medication status.

The charge nurse of the medical-surgical unit is making staff assignments. Which staff member should be assigned to a client with chronic kidney disease who is exhibiting a low-grade fever and a pericardial friction rub?
- A. Registered nurse who just floated from the surgical unit
- B. Registered nurse who just floated from the dialysis unit
- C. Registered nurse who was assigned the same client yesterday
- D. Licensed practical nurse with 5 years of experience on this floor
Correct Answer: C
Rationale: The client is exhibiting symptoms of pericarditis, which can occur with chronic kidney disease. Continuity of care is crucial to assess subtle changes in clients' conditions. Therefore, the registered nurse (RN) who previously cared for this client should be assigned again. Float nurses may lack knowledge of the unit and its clients, potentially leading to oversight of critical details. The licensed practical nurse, while experienced, may not possess the advanced assessment skills and education level of an RN to effectively evaluate and manage pericarditis in this client.
A marathon runner comes into the clinic and states, 'I have not urinated very much in the last few days.' The nurse notes a heart rate of 110 beats/min and a blood pressure of 86/58 mm Hg. Which action by the nurse is the priority?
- A. Give the client a bottle of water immediately.
- B. Start an intravenous line for fluids.
- C. Teach the client to drink 2 to 3 liters of water daily.
- D. Perform an electrocardiogram.
Correct Answer: A
Rationale: The priority action for the nurse is to give the client a bottle of water immediately. The athlete's symptoms of decreased urination, along with a heart rate of 110 beats/min and low blood pressure of 86/58 mm Hg, indicate mild dehydration. Rehydration should begin promptly to address the dehydration. Teaching the client to drink 2 to 3 liters of water daily is a good long-term strategy but not the immediate priority. Starting an intravenous line for fluids may be necessary if oral hydration is insufficient or if the degree of dehydration is severe. Performing an electrocardiogram is not indicated at this time as the priority is addressing the dehydration.
The patient is receiving sulfadiazine. The healthcare provider knows that this patient's daily fluid intake should be at least which amount?
- A. 1000 mL/day
- B. 1200 mL/day
- C. 2000 mL/day
- D. 2400 mL/day
Correct Answer: C
Rationale: Sulfadiazine may lead to crystalluria, a condition where crystals form in the urine. Adequate fluid intake helps prevent this adverse effect by ensuring urine is dilute enough to prevent crystal formation. The recommended daily fluid intake for a patient receiving sulfadiazine is at least 2000 mL/day. Choices A, B, and D are incorrect because they do not provide a sufficient amount of fluid intake to prevent crystalluria in patients on sulfadiazine.
A nurse cares for a client with diabetes mellitus who is prescribed metformin (Glucophage) and is scheduled for an intravenous urography. Which action should the nurse take first?
- A. Contact the provider and recommend discontinuing the metformin.
- B. Keep the client NPO for at least 6 hours prior to the examination.
- C. Check the client's capillary artery blood glucose and administer prescribed insulin.
- D. Administer intravenous fluids to dilute and increase the excretion of dye.
Correct Answer: A
Rationale: Metformin can cause lactic acidosis and renal impairment as the result of an interaction with the dye. This drug must be discontinued for 48 hours before the procedure and not started again after the procedure until urine output is well established. The client's health care provider needs to provide alternative therapy for the client until the metformin can be resumed. Keeping the client NPO, checking the client's blood glucose, and administering intravenous fluids should be part of the client's plan of care, but are not the priority, as the examination should not occur while the client is still taking metformin.
The nurse is caring for a newly admitted patient who has severe gastroenteritis. The patient's electrolytes reveal a serum sodium level of 140 mEq/L and a serum potassium level of 3.5 mEq/L. The nurse receives an order for intravenous 5% dextrose and normal saline with 20 mEq/L potassium chloride to infuse at 125 mL per hour. Which action is necessary prior to administering this fluid?
- A. Evaluate the patient's urine output.
- B. Contact the provider to order arterial blood gases.
- C. Request an order for an initial potassium bolus.
- D. Suggest a diet low in sodium and potassium.
Correct Answer: A
Rationale: Prior to administering IV fluids containing potassium, it is crucial to evaluate the patient's urine output. If the urine output is less than 25 mL/hr or 600 mL/day, there is a risk of potassium accumulation. Patients with low urine output should not receive IV potassium to prevent potential complications. Contacting the provider for arterial blood gases is unnecessary in this scenario as it does not directly relate to the administration of IV fluids with potassium. Administering potassium as a bolus is not recommended due to potential adverse effects. While dietary considerations are important, suggesting a low-sodium and low-potassium diet is not the immediate action required before administering IV fluids with potassium chloride.
