Question 1 of 5
The nurse has been encouraging the intake of oral fluids for a client in labor to improve hydration. Which indicates a successful outcome of this action?
Correct Answer: B
Rationale: Urine specific gravity measures the concentration of the urine. During the first stage of labor, the renal system has a tendency to concentrate urine. Labor and birth require hydration and caloric intake to replenish energy expenditure and promote efficient uterine function. An elevated blood pressure and ketones in the urine are not expected outcomes related to labor and hydration. After the membranes have ruptured, it is expected that amniotic fluid may continue to leak.
Question 2 of 5
The nurse is caring for a client who has returned from the postanesthesia care unit after prostatectomy. The client has a three-way Foley catheter with an infusion of continuous bladder irrigation (CBI). Which color description of the urinary drainage should lead the nurse to determine that the flow rate is adequate?
Correct Answer: C
Rationale: The infusion of bladder irrigant is not at a preset rate; rather, it is increased or decreased to maintain urine that is a clear, pale yellow color or has just a slight pink tinge. The infusion rate should be increased if the drainage is cherry colored or if clots are seen. Alternatively, the rate can be slowed down slightly if the returns are as clear as water.
Question 3 of 5
The nurse has provided discharge instructions to the parent of a child who has undergone heart surgery. Which statement by the parent would indicate the need for further instruction?
Correct Answer: A
Rationale: The child may return to school the third week after hospital discharge, but he or she should go to school for half days for the first week. Outside play should be omitted for several weeks, with inside play allowed as tolerated. The child should avoid crowds of people for 2 weeks after discharge, including crowds at day care centers and churches. If any difficulty with breathing occurs, the parent should notify the primary health care provider.
Question 4 of 5
A client has begun medication therapy with betaxolol. The nurse determines that the client is experiencing the intended effect of therapy if which observation is noted?
Correct Answer: D
Rationale: Betaxolol is a beta-adrenergic blocking agent used to lower blood pressure, relieve angina, or eliminate dysrhythmias. Side/adverse effects include bradycardia and symptoms of heart failure, such as weight gain and increased edema.
Question 5 of 5
The nurse is caring for a client on mechanical ventilation via an oral endotracheal tube. What are the possible causes of the high-pressure alarm sounding?
Correct Answer: A,B,C,E
Rationale: The high-pressure alarm sounds when the peak inspiratory pressure reaches the set alarm limit. Causes include obstruction of the endotracheal tube because of the client lying on the tube or water or a kink in the tubing; the client being anxious or fighting the ventilator; an increased amount of secretions in the airways or a mucous plug; the client coughing, gagging, or biting on the oral endotracheal tube; decreased airway size related to wheezing or bronchospasm; pneumothorax; and displacement of the artificial airway and the endotracheal tube slipping into the right main stem bronchus. The low-pressure alarm sounds when there is a leak or disconnection in the ventilator circuit or a leak in the client's artificial airway cuff.
