Nursing Elites

1. A nurse in the emergency department is preparing to care for a client who arrived via ambulance. The client is disoriented and has a cardiac arrhythmia. Which of the following actions should the nurse take?

• A. Proceed with treatment without obtaining written consent
• B. Contact the client's next of kin to obtain consent for treatment
• C. Have the client sign a consent for treatment
• D. Notify risk management before initiating treatment

Correct answer: A

Rationale: In emergency situations where a client is disoriented and has a cardiac arrhythmia, obtaining written consent may not be possible due to the urgency of the situation. The priority is to provide immediate treatment to ensure patient safety. Contacting the next of kin or having the client sign a consent form would cause unnecessary delays in providing critical care. Notifying risk management before initiating treatment is not the most appropriate action when dealing with a time-sensitive situation like a cardiac arrhythmia.

2. The doctor has ordered 500 mg of a medication PO once a day. The tablets on hand are labeled as 1 tablet = 250 mg. How many tablets will you administer to your patient?

• A. 1 Tablet
• B. 2 Tablets
• C. 3 Tablets
• D. 4 Tablets

Correct answer: B

Rationale: To calculate the number of tablets needed, divide the total dosage prescribed (500 mg) by the dosage per tablet (250 mg per tablet). 500 mg / 250 mg per tablet = 2 tablets. Therefore, the correct answer is 2 tablets. Choices A, C, and D are incorrect as they do not accurately reflect the correct calculation based on the provided information.

3. During which stage of anesthesia is a patient most likely to experience involuntary motor activity?

• A. Stage I
• B. Stage II
• C. Stage III
• D. Stage VI

Correct answer: B

Rationale: The correct answer is Stage II. During Stage II of anesthesia, a patient is most likely to experience involuntary motor activity. This stage is known as the excitement stage, where the patient may exhibit purposeful or involuntary movements. Choice A (Stage I) is incorrect because Stage I is the induction phase where the patient is transitioning from consciousness to unconsciousness, and involuntary motor activity is less likely to occur. Choice C (Stage III) is incorrect as it is the stage of surgical anesthesia characterized by muscle relaxation, and involuntary motor activity is less common during this stage. Choice D (Stage VI) is incorrect as there is no Stage VI in the standard stages of anesthesia. Therefore, the most appropriate stage where involuntary motor activity is likely to occur is Stage II.

4. Select the stage of shock that is accurately paired with its characteristic.

• A. The initial stage of shock: Hyperventilation occurs and the blood pH rises.
• B. The compensatory stage of shock: Hypoxia occurs and lactic acid rises.
• C. The progressive stage of shock: Histamine is released; fluid and proteins leak into surrounding tissues and the blood thickens.
• D. The refractory stage of shock: Potassium ions leak out; sodium ions build up, and metabolic acidosis increases.

Correct answer: C

Rationale: The progressive stage of shock is accurately described as the stage where histamine is released, leading to fluid and proteins leaking into surrounding tissues and the blood thickening. In this stage, the body's compensatory mechanisms are overwhelmed, resulting in a cascade of events that worsen the shock state. Choice A is incorrect as hyperventilation and a rise in blood pH are more characteristic of the compensatory stage. Choice B is incorrect as hypoxia and a rise in lactic acid are more typical of the progressive stage. Choice D is incorrect as the described electrolyte imbalances and metabolic acidosis are more aligned with the refractory stage of shock.

5. Which patient is at greatest risk for papilledema?

• A. An elderly patient with cataracts and macular degeneration
• B. A male patient with hypothyroidism
• C. A male patient with hyperthyroidism
• D. An adolescent with a closed head injury

Correct answer: D

Rationale: An adolescent with a closed head injury is at the highest risk for papilledema due to increased intracranial pressure. Papilledema is often a consequence of elevated intracranial pressure, which can occur in conditions like head trauma. Choices A, B, and C do not directly correlate with an increased risk of papilledema compared to a closed head injury, which is more likely to lead to elevated intracranial pressure and subsequent papilledema.
