1. A client who received multiple antihypertensive medications experiences syncope due to a drop in blood pressure to 70/40. What is the rationale for the nurse’s decision to hold the client’s scheduled antihypertensive medication?
- A. Increased urinary clearance of the multiple medications has led to diuresis and lowered the blood pressure.
- B. The antagonistic interaction among the various blood pressure medications has reduced their effectiveness.
- C. The additive effect of multiple medications has caused the blood pressure to drop too low.
- D. The synergistic effect of the multiple medications has resulted in drug toxicity and resulting hypotension.
Correct answer: C
Rationale: The correct answer is C. When a client experiences syncope due to a significant drop in blood pressure after receiving multiple antihypertensive medications, the additive effect of these medications can cause the blood pressure to drop excessively. This additive effect can lead to hypotension, which is why the nurse decided to hold the client's scheduled antihypertensive medication. Choices A, B, and D provide incorrect rationales. Choice A mentions diuresis, which is not directly related to the drop in blood pressure due to additive medication effects. Choice B refers to an antagonistic interaction reducing effectiveness, which is not applicable in this scenario. Choice D talks about a synergistic effect leading to drug toxicity, which is not the cause of the sudden drop in blood pressure observed in the client.
2. An adult suffered burns to the face and chest resulting from a grease fire. On admission, the client was intubated, and a 2-liter bolus of normal saline was administered IV. Currently, the normal saline is infusing at 250 ml/hour. The client’s heart rate is 120 beats/minute, blood pressure is 90/50 mmHg, respirations are 12 breaths/minute over the ventilated 12 breaths for a total of 24 breaths/minute, and the central venous pressure (CVP) is 4 mm H2O. Which intervention should the nurse implement?
- A. Increase the rate of normal saline infusion
- B. Infuse an additional bolus of normal saline
- C. Lower the head of the bed to a recumbent position
- D. Bring a tracheostomy tray to the bedside
Correct answer: B
Rationale: The correct intervention is to infuse an additional bolus of normal saline. The client's presentation with a heart rate of 120 beats/minute, hypotensive blood pressure of 90/50 mmHg, and low CVP of 4 mm H2O indicates hypovolemic shock. Administering more normal saline can help in restoring intravascular volume and improving perfusion. Increasing the rate of normal saline infusion (Choice A) is not the best choice as it may lead to fluid overload. Lowering the head of the bed to a recumbent position (Choice C) could worsen hypotension by reducing venous return. Bringing a tracheostomy tray to the bedside (Choice D) is not a priority at this time as the client is already intubated, and the immediate concern is addressing the hypovolemia.
3. A woman at 24-weeks gestation who has fever, body aches, and has been coughing for the last 5 days is sent to the hospital with admission prescriptions for H1N1 influenza. Which action has the highest priority?
- A. Administer Ringer's Lactate IV 125ml/8 hours
- B. Obtain specimens for cultures
- C. Assign a private room
- D. Monitor vital signs q4 hours
Correct answer: C
Rationale: Assigning a private room has the highest priority in this scenario. It helps prevent the spread of H1N1 influenza to other patients and protects both the patient and others from potential infection. Obtaining specimens for cultures and monitoring vital signs are important but do not address the immediate need to prevent the spread of the virus. Administering Ringer's Lactate IV is not the priority in this case as it does not directly address the infectious nature of the condition.
4. The client has silvery scaling plaques bilaterally on elbows, forearms, and palms. When scratched, the skin bleeds over these plaques. What is most important to include in this client’s plan of care?
- A. Interventions to decrease emotional stress
- B. Precautions about avoiding sunlight
- C. Strategies to increase omega-3 fatty acids in the diet
- D. Instruct about applying a corticosteroid cream
Correct answer: A
Rationale: The most important aspect to include in this client's plan of care is interventions to decrease emotional stress. Psoriasis, characterized by silvery scaling plaques on the skin, can be exacerbated by emotional stress. Managing stress is crucial in controlling the condition. Precautions about avoiding sunlight are important in psoriasis management, but emotional stress has a more significant impact. While omega-3 fatty acids may provide some benefits, stress management should take priority. Applying a corticosteroid cream may help with symptoms, but addressing emotional stress is crucial for long-term management of psoriasis.
5. A 14-year-old male client with a spinal cord injury (SCI) at T-10 is admitted for rehabilitation. During the morning assessment, the nurse determines that the adolescent's face is flushed, his forehead is sweating, his heart rate is 54 beats/min, and his blood pressure is 198/118. What action should the nurse implement first?
- A. Determine if the urinary bladder is distended
- B. Irrigate the indwelling urinary catheter
- C. Review the temperature graph for the last day
- D. Administer an antihypertensive agent
Correct answer: A
Rationale: Autonomic dysreflexia is a potentially life-threatening emergency that can be triggered by a distended bladder in clients with spinal cord injuries at T-6 or above. The priority action is to determine if the urinary bladder is distended as this could be the cause of the symptoms observed in the adolescent. Flushing, sweating, bradycardia, and severe hypertension are classic signs of autonomic dysreflexia. Irrigating the urinary catheter, reviewing temperature graphs, or administering an antihypertensive agent are not the initial actions to take when suspecting autonomic dysreflexia.
