Nursing Elites

1. A nurse is assessing a client who has a brainstem injury. The nurse should expect the client to exhibit which of the following findings?

• A. Decerebrate posturing.
• B. Hypervigilance.
• C. Absence of deep tendon reflexes.
• D. Glasgow Coma Scale score of 15.

Correct answer: A

Rationale: The correct answer is A: Decerebrate posturing. Decerebrate posturing is an abnormal body posture characterized by rigid extension of the arms and legs, which indicates severe brainstem injury affecting the midbrain and pons. This posture suggests dysfunction or damage to neural pathways controlling muscle tone. Choice B, hypervigilance, is not typically associated with brainstem injury but rather with increased alertness and arousal. Choice C, absence of deep tendon reflexes, is not a specific finding related to brainstem injury. Choice D, a Glasgow Coma Scale score of 15, indicates a fully awake and alert state, which is not expected in a client with a brainstem injury.

2. What intervention is essential for a client with dehydration?

• A. Monitor electrolyte levels regularly
• B. Administer oral rehydration solutions
• C. Increase fluid intake to maintain hydration
• D. Administer intravenous fluids to treat dehydration

Correct answer: B

Rationale: Administering oral rehydration solutions is essential for a client with dehydration as it helps replenish lost fluids and electrolytes directly through the oral route. Monitoring electrolyte levels regularly (Choice A) is important but not as essential as providing immediate rehydration. Increasing fluid intake to maintain hydration (Choice C) may not be sufficient for a client already dehydrated and needing rapid replenishment. Administering intravenous fluids (Choice D) is a more invasive intervention typically reserved for severe cases of dehydration or when the client cannot tolerate oral fluids.

3. What are the signs and symptoms of hyperkalemia and how should it be managed?

• A. Muscle weakness and cardiac arrhythmias; administer calcium gluconate
• B. Confusion and bradycardia; administer insulin and glucose
• C. Fatigue and irregular heart rate; administer diuretics
• D. Nausea and vomiting; administer sodium bicarbonate

Correct answer: A

Rationale: The signs and symptoms of hyperkalemia include muscle weakness and cardiac arrhythmias, making choice A correct. Hyperkalemia can lead to dangerous cardiac effects, and calcium gluconate is used to stabilize the heart by antagonizing the effects of potassium. Choices B, C, and D describe symptoms and interventions that are not typically associated with hyperkalemia. Confusion and bradycardia are not common in hyperkalemia, and insulin and glucose are used in hyperkalemia only under specific circumstances. Fatigue and irregular heart rate are vague symptoms, and diuretics are not the primary treatment for hyperkalemia. Nausea and vomiting are nonspecific symptoms and sodium bicarbonate is not indicated for the management of hyperkalemia.

4. A nurse is caring for a client who has dementia and frequently gets out of bed unsupervised. What is the best intervention to prevent falls?

• A. Place a bed exit alarm
• B. Use restraints to prevent the client from getting out of bed
• C. Ask the client's family to stay at the bedside
• D. Encourage frequent ambulation with assistance

Correct answer: A

Rationale: The best intervention to prevent falls in a client with dementia who gets out of bed unsupervised is to place a bed exit alarm. This device alerts staff when the client attempts to leave the bed, allowing timely intervention to reduce the risk of falls. Using restraints (choice B) can lead to physical and psychological harm and should be avoided unless absolutely necessary. Asking the client's family to stay at the bedside (choice C) may not be feasible at all times and does not provide a continuous monitoring solution. Encouraging frequent ambulation with assistance (choice D) is beneficial for mobility but may not address the immediate risk of falls associated with unsupervised bed exits.

5. A client with hypothyroidism may present with which of the following findings?

• A. Weight gain
• B. Hair loss
• C. Dry skin
• D. Diarrhea

Correct answer: C

Rationale: Dry skin is a common manifestation of hypothyroidism due to decreased thyroid hormone levels, leading to reduced sweating and oil production. Weight gain may occur due to a slowed metabolism, not diarrhea, as hypothyroidism is more commonly associated with constipation. Hair loss is typically associated with hyperthyroidism, not hypothyroidism.
