1. A client is receiving lidocaine IV at 3 mg/minute. The pharmacy dispenses a 500 ml IV solution of normal saline (NS) with 2 grams of lidocaine. The nurse should regulate the infusion pump to deliver how many ml/hour?

Correct answer: D

Rationale: The infusion rate is calculated based on the concentration of lidocaine and the prescribed rate of infusion. First, convert lidocaine's weight to milligrams (2 grams = 2000 mg). Then, use the formula: (Total volume in ml * dose in mg) / 60 minutes. For this case, (500 ml * 2000 mg) / 60 minutes = 45 ml/hour. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the accurate calculation based on the provided concentration and infusion rate.

2. A male client with schizophrenia is jerking his neck and smacking his lips. Which finding indicates to the nurse that he is experiencing an irreversible side effect of antipsychotic agents?

Correct answer: B

Rationale: The correct answer is B: Worming movements of the tongue. Worming movements of the tongue, known as tardive dyskinesia, are an irreversible side effect of antipsychotic medications. Tardive dyskinesia is characterized by involuntary, repetitive movements of the tongue, lips, face, trunk, and extremities. Cramping muscular pain (Choice A) is more indicative of dystonia, an extrapyramidal side effect that can be treated effectively with antiparkinsonian medications. Decreased tendon reflexes (Choice C) are not typically associated with irreversible side effects of antipsychotic agents. Dry oral mucous membranes (Choice D) are not specific to irreversible side effects of antipsychotic medications.

3. After removing an IV that became infiltrated in the client’s left forearm, which site should the nurse select as a possible site to insert another IV catheter?

Correct answer: A

Rationale: The correct answer is A: Right hand. When an IV becomes infiltrated in the client's left forearm, it is essential to avoid the same side due to the risk of complications. Therefore, the right hand is a suitable alternative site for IV insertion. Choices B, C, and D are incorrect. Choosing the right forearm (B) would still be on the same side, which increases the risk of complications. The left hand (C) is not a preferred option immediately after an infiltration in the left forearm. The right subclavian (D) is an invasive site typically reserved for central line placement and not a first-line choice for IV insertion.

4. Following a gunshot wound, an adult client has a hemoglobin level of 4 grams/dl (40 mmol/L SI). The nurse prepares to administer a unit of blood for an emergency transfusion. The client has AB negative blood type and the blood bank sends a unit of type A Rh negative, reporting that there is not type AB negative blood currently available. Which intervention should the nurse implement?

Correct answer: A

Rationale: In emergency situations where AB negative blood is unavailable, type A negative blood can be transfused to a patient with AB negative blood type. Type A negative blood is compatible with AB negative blood, making it a suitable option until the correct blood type becomes available. Transfusion of Type A negative blood is crucial to address the severe anemia promptly. Rechecking the client’s hemoglobin, blood type, and Rh factor (Choice B) may delay necessary treatment. Administering normal saline solution (Choice C) is not a substitute for blood transfusion in cases of severe anemia. Obtaining additional consent for the administration of type A negative blood (Choice D) is unnecessary as the situation is emergent and the blood type is compatible.

5. The nurse is assessing a client with pulmonary edema who is reporting two-pillow orthopnea and paroxysmal nocturnal dyspnea. The nurse identifies rapid shallow respirations and the use of accessory muscles. Which action should the nurse include in the client’s plan of care?

Correct answer: A

Rationale: Administering amiodarone is appropriate if arrhythmias are present in the context of pulmonary edema, as it helps manage irregular heart rhythms. In this case, the client is experiencing symptoms related to respiratory distress, and amiodarone can address potential arrhythmias contributing to the condition. Options B and D are not directly related to managing symptoms of pulmonary edema and do not address the underlying cause of the client's distress. Option C, performing blood tests for cardiac enzymes, is important for assessing possible myocardial damage but does not directly address the immediate respiratory distress associated with pulmonary edema.
