Nursing Elites

1. A nurse is teaching a client about using a continuous positive airway pressure (CPAP) device to treat obstructive sleep apnea. Which of the following information should the nurse include in the teaching?

• A. It delivers a preset amount of inspiratory pressure throughout the breathing cycle
• B. It has a continuous adjustment feature that changes the airway pressure throughout the cycle
• C. It delivers a preset amount of airway pressure throughout the breathing cycle
• D. It delivers positive pressure at the end of each breath

Correct answer: C

Rationale: The correct answer is C because a CPAP device delivers a preset amount of positive airway pressure continuously throughout all inspiration and expiration cycles. Choice A is incorrect because CPAP does not deliver inspiratory pressure at the beginning of each breath; it provides continuous positive pressure. Choice B is incorrect because CPAP typically delivers a constant pressure rather than having a feature that changes pressure throughout the cycle. Choice D is incorrect as CPAP does not deliver positive pressure specifically at the end of each breath; it maintains a consistent pressure throughout the breathing cycle.

2. A patient who experienced an acute episode of gastritis should avoid which type of foods?

• A. Avoid foods high in potassium
• B. Avoid foods high in sodium
• C. Increase exercise
• D. Drink milk as a snack

Correct answer: A

Rationale: Patients who have experienced an acute episode of gastritis should avoid foods high in potassium. Potassium-rich foods can irritate the gastric lining, exacerbating gastritis symptoms. Therefore, choices B, C, and D are incorrect. Avoiding foods high in sodium is beneficial for other health conditions like hypertension, increasing exercise is generally good for overall health but not specifically for gastritis management, and drinking milk may provide temporary relief for some but is not a definitive recommendation for gastritis management.

3. A nurse is caring for a client who has been experiencing repeated tonic-clonic seizures over the course of 30 minutes. After maintaining the client's airway and turning the client on their side, which of the following medications should the nurse administer?

• A. Diazepam IV
• B. Lorazepam PO
• C. Diltiazem IV
• D. Clonazepam PO

Correct answer: A

Rationale: In the scenario described, where the client has been experiencing repeated tonic-clonic seizures over an extended period, the priority is to administer a medication that can rapidly terminate the seizures. Diazepam is the medication of choice for status epilepticus due to its rapid onset of action within 10 minutes when administered intravenously. Lorazepam is also an option, but it is typically administered intravenously as well. Diltiazem is a calcium channel blocker used for conditions like hypertension and angina, not for seizures. Clonazepam, although used for seizures, is not the ideal choice in this acute situation due to its slower onset of action compared to benzodiazepines like diazepam and lorazepam.

4. What ECG changes are expected in hypokalemia?

• A. Flattened T waves on ECG
• B. Prominent U waves on ECG
• C. Widened QRS complexes on ECG
• D. ST elevation on ECG

Correct answer: A

Rationale: In hypokalemia, flattened T waves are a common ECG finding due to the decreased extracellular potassium affecting repolarization. Prominent U waves are typically seen in hypokalemia as well, but flattened T waves are the more specific and early ECG change. Widened QRS complexes are associated with hyperkalemia, not hypokalemia. ST elevation is often seen in conditions like myocardial infarction, pericarditis, or early repolarization syndrome, not specifically in hypokalemia.

5. What are the expected symptoms in a patient experiencing a thrombotic stroke?

• A. Gradual loss of function on one side of the body
• B. Sudden loss of consciousness
• C. Seizures and convulsions
• D. Severe headache and vomiting

Correct answer: A

Rationale: The correct answer is A: 'Gradual loss of function on one side of the body.' Thrombotic strokes typically result in a gradual onset of symptoms due to a blockage in a blood vessel in the brain, leading to a slow progression of neurological deficits. Choices B, C, and D are incorrect because sudden loss of consciousness, seizures, convulsions, severe headache, and vomiting are more commonly associated with other types of strokes or medical conditions, such as hemorrhagic strokes, epilepsy, or migraines.
