1. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?

Correct answer: A

Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.

2. A client asks the nurse about including her 2 and 12-year-old sons in the care of their newborn sister. Which of the following is an appropriate initial statement by the nurse?

Correct answer: A

Rationale: It is essential for the nurse to guide the client on the initial steps in involving her 2 and 12-year-old sons in the care of their newborn sister. The most appropriate response is to 'Focus on your sons' needs during the first days at home.' In an expanded family, parents should prioritize reassuring older children that they are loved and as important as the newborn. This response acknowledges the importance of ensuring the well-being and emotional adjustment of the older siblings during the transition period. Choices B, C, and D are less appropriate as they do not directly address the emotional needs and adjustment of the older children during this significant family change.

3. The nurse is caring for a client in the late stages of Amyotrophic Lateral Sclerosis (A.L.S.). Which finding would the nurse expect?

Correct answer: C

Rationale: In the late stages of Amyotrophic Lateral Sclerosis (A.L.S.), respiratory muscles are affected, leading to shallow respirations. Confusion is not typically associated with A.L.S. Loss of half of the visual field suggests a neurological issue unrelated to A.L.S., while tonic-clonic seizures are not commonly seen in A.L.S. patients. Shallow respirations are a hallmark sign of respiratory muscle weakness in A.L.S. due to the degeneration of motor neurons.

4. The healthcare professional in the Emergency Room is treating a patient suspected to have a Peptic Ulcer. On assessing lab results, the healthcare professional finds that the patient's blood pressure is 95/60, pulse is 110 beats per minute, and the patient reports epigastric pain. What is the PRIORITY intervention?

Correct answer: A

Rationale: The priority intervention in this scenario is to start a large-bore IV in the patient's arm. The patient's low blood pressure (95/60) and elevated pulse rate (110 beats per minute) indicate a potential hemorrhage, requiring immediate fluid resuscitation. Starting a large-bore IV will allow for rapid administration of fluids to stabilize the patient's condition. Asking for a stool sample, preparing to insert an NG tube, or administering morphine sulfate should not take precedence over addressing the hemodynamic instability and potential hemorrhage observed in the patient. These actions may be considered later in the patient's care, but the primary focus should be on addressing the critical issue of fluid replacement and stabilization.

5. A patient has taken an overdose of aspirin. Which of the following should a nurse closely monitor during acute management of this patient?

Correct answer: A

Rationale: The correct answer is to monitor the onset of pulmonary edema. In cases of aspirin overdose, metabolic acidosis is a common consequence that can lead to the development of pulmonary edema. Early signs of aspirin poisoning include symptoms like tinnitus, hyperventilation, vomiting, dehydration, and fever. Late signs may manifest as drowsiness, bizarre behavior, unsteady walking, and coma. Aspirin poisoning can cause abnormal breathing that is typically rapid and deep. Pulmonary edema may occur due to increased capillary permeability in the lungs, leading to the leakage of proteins and fluid transudation in renal and pulmonary tissues. Changes in renal tubule permeability can also affect colloid osmotic pressure, potentially contributing to pulmonary edema. Monitoring pulmonary edema is crucial in managing aspirin overdose cases to prevent further complications. Choices B, C, and D are incorrect because metabolic alkalosis, respiratory alkalosis, and Parkinson's disease type symptoms are not typically associated with aspirin overdose and are not primary concerns in its acute management.
