Nursing Elites

1. Because of the possible nervous system side-effects that occur with isoniazid (Nydrazid) therapy, which supplementary nutritional agent would the nurse teach the client to take as a prophylaxis?

• A. Alpha tocopherol (vitamin E)
• B. Ascorbic acid (vitamin C)
• C. Calcitriol (vitamin D)
• D. Pyridoxine (vitamin B6)

Correct answer: D

Rationale: Pyridoxine is the correct choice in this scenario because it is used as a prophylaxis to prevent neuritis, a possible nervous system side-effect of isoniazid therapy. Neuritis is a condition that involves inflammation of the nerves and can be a side effect of isoniazid. Pyridoxine, also known as vitamin B6, helps prevent this side effect. Vitamin E (Alpha tocopherol), vitamin C (Ascorbic acid), and vitamin D (Calcitriol) do not specifically address the nervous system side-effects associated with isoniazid therapy, making them incorrect choices.

2. While making rounds at 3 am, the nurse discovers a small fire in a client's room. What should the nurse do first?

• A. Remove the client from the room immediately.
• B. Leave the client's room to obtain a fire extinguisher.
• C. Instruct a nurse tech to pull the fire alarm.
• D. Evacuate all clients from the unit.

Correct answer: A

Rationale: During a fire emergency, the priority is the safety of the individual in the room where the fire is located. Removing the client from the room immediately is the first step in the RACE acronym for fire safety: Rescue/Remove, Alarm, Contain, and Extinguish. This action ensures the client's safety before addressing the fire itself. Choice B is incorrect as leaving the client's room to obtain a fire extinguisher can delay the immediate removal of the client from the danger. Choice C is incorrect as pulling the fire alarm should be done after ensuring the client's safety. Choice D is incorrect as evacuating all clients from the unit should come after ensuring the safety of the individual in immediate danger.

3. A client is admitted to the critical care unit after suffering from a massive cerebral vascular accident. The client's vital signs include BP 160/110, HR 42, Cheyne-Stokes respirations. Based on this assessment, the nurse anticipates the client to be in which acid-base balance?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: A

Rationale: In this scenario, the client is exhibiting Cheyne-Stokes respirations, which are characterized by periods of deep breathing alternating with apnea. This pattern indicates respiratory insufficiency, resulting in an accumulation of carbon dioxide in the blood. The elevated BP and slow heart rate further support the respiratory insufficiency, leading to respiratory acidosis. Therefore, the correct answer is Respiratory acidosis. Choices B, C, and D are incorrect. Respiratory alkalosis is characterized by decreased carbon dioxide levels in the blood, which is not indicated by the client's presentation. Metabolic acidosis results from conditions such as renal failure or diabetic ketoacidosis and is not the primary imbalance in this case. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels, which are not present in the client's vital signs.

4. While undergoing hemodialysis, the client becomes restless and tells the nurse he has a headache and feels nauseous. Which of the following complications does the nurse suspect?

• A. Infection.
• B. Disequilibrium syndrome.
• C. Air embolus.
• D. Infection.

Correct answer: C

Rationale: In this scenario, the client undergoing hemodialysis is experiencing symptoms like restlessness, a headache, and nausea. These symptoms are indicative of an air embolus, a serious complication that can occur during hemodialysis. Air embolus happens when air enters the bloodstream and can lead to symptoms like restlessness, a headache, and nausea. It is crucial for the nurse to suspect and address this complication promptly to prevent further harm to the client. Choices A and D (Infection) are less likely in this case, as the symptoms presented are more suggestive of an air embolus rather than an infection. Choice B (Disequilibrium syndrome) is also less likely as the symptoms described are not typical of this syndrome. Therefore, the correct answer is C: Air embolus.

5. A client arrives in the emergency department after severely lacerating the left hand with a knife. HR 96, BP 150/88, R36. The client is extremely anxious and crying uncontrollably. Based on this assessment, the nurse anticipates that this client would be in which acid-base imbalance?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: B

Rationale: The correct answer is respiratory alkalosis. Hyperventilation due to anxiety, pain, shock, severe infection, fever, or liver failure can lead to respiratory alkalosis. In this scenario, the client is extremely anxious and crying uncontrollably, indicating an increased respiratory rate and CO2 loss. Respiratory acidosis (choice A) is incorrect as it is characterized by an increase in CO2 levels, not a loss. Metabolic acidosis (choice C) involves a decrease in blood pH due to an accumulation of acids or loss of bicarbonate, which is not the case here. Metabolic alkalosis (choice D) results from excess bicarbonate or a loss of acids, not from increased CO2 loss due to hyperventilation.
