1. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the nurse set the client's intravenous infusion pump?
- A. 13 ml/hour.
- B. 63 ml/hour.
- C. 80 ml/hour.
- D. 125 ml/hour.
Correct answer: B
Rationale: The correct calculation involves dividing the total volume by the total time. In this case, 250 ml/4 hours = 63 ml/hour. The dose of KCl is not used in the calculation as the focus is on the rate of infusion over the specified time period. Choice A (13 ml/hour) is incorrect as it does not result from the correct calculation. Choice C (80 ml/hour) and Choice D (125 ml/hour) are also incorrect calculations and do not match the correct rate of infusion required.
2. The client is being taught how to self-administer a subcutaneous injection. To ensure sterility of the procedure, which subject is most important for the instructor to include in the teaching plan?
- A. Hand washing before preparing the injection.
- B. Technique for drawing medication from a vial.
- C. Selection and rotation of injection sites.
- D. Proper disposal of injection equipment.
Correct answer: B
Rationale: To maintain the sterility of the procedure, it is crucial to teach the client the correct technique for drawing medication from a vial. This ensures that the medication remains sterile during preparation and administration. While hand washing, injection site selection, and equipment disposal are important aspects of injection safety, the key focus should be on maintaining the sterility of the medication itself to prevent infections and ensure the effectiveness of the treatment.
3. A client is admitted with a diagnosis of fluid volume deficit. Which clinical finding would the nurse expect?
- A. Bounding pulse
- B. Bradycardia
- C. Oliguria
- D. Dry mucous membranes
Correct answer: D
Rationale: Dry mucous membranes (D) are a common clinical finding indicating fluid volume deficit. In dehydration, there is insufficient fluid in the body, leading to dry mucous membranes due to decreased saliva production. Bounding pulse (A) is associated with fluid volume excess, not deficit. Bradycardia (B) and oliguria (C) are not typical clinical findings of fluid volume deficit but may be seen in fluid volume excess or other conditions.
4. Which assessment data indicates the need for the nurse to include the problem 'Risk for falls' in a client’s plan of care?
- A. Recent serum hemoglobin level of 16 g/dL
- B. Opioid analgesic received one hour ago
- C. Stooped posture with an unsteady gait
- D. Expressed feelings of depression
Correct answer: B
Rationale: The correct answer is B. The administration of opioid analgesics can impair balance and increase the risk of falls, justifying the inclusion of 'Risk for falls' in the client’s care plan. Choice A, a recent serum hemoglobin level of 16 g/dL, is not directly related to the risk of falls. Choice C, stooped posture with an unsteady gait, may indicate a risk for falls, but the direct influence of opioid analgesics on balance is more immediate. Choice D, expressed feelings of depression, while important, is not a direct indicator of the immediate risk for falls associated with opioid analgesic use.
5. A client with a diagnosis of hyperkalemia is receiving sodium polystyrene sulfonate (Kayexalate). Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?
- A. Serum sodium level.
- B. Serum potassium level.
- C. Serum calcium level.
- D. Serum glucose level.
Correct answer: B
Rationale: The correct answer is B: Serum potassium level. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Monitoring the serum potassium level allows the nurse to assess the effectiveness of this medication in lowering the elevated potassium levels. Serum sodium (A), calcium (C), and glucose (D) levels are not directly impacted by the action of sodium polystyrene sulfonate.
