A nurse is caring for a client who has an acute respiratory failure (ARF). The nurse should monitor the client for which of the following manifestations of this condition? (Select all that apply.)
Nausea
Severe dyspnea
Headache
Decreased level of consciousness
Hypotension
Correct Answer : B,C,D,E
Choice a) is incorrect because nausea is not a common manifestation of ARF. Nausea is a sensation of discomfort in the stomach that may or may not lead to vomiting. Nausea can be caused by many other conditions, such as gastroenteritis, motion sickness, or pregnancy.
Choice b) is correct because severe dyspnea is a common manifestation of ARF. Dyspnea is a subjective feeling of difficulty or discomfort in breathing. Severe dyspnea indicates that the client is not getting enough oxygen and may have low blood oxygen levels (hypoxemia) or high carbon dioxide levels (hypercapnia).
Choice c) is correct because headache is a common manifestation of ARF. Headache is a pain or discomfort in the head, scalp, or neck. Headache can be caused by high carbon dioxide levels (hypercapnia), which can affect the blood vessels and nerves in the brain.
Choice d) is correct because a decreased level of consciousness is a common manifestation of ARF. Level of consciousness is a measure of how alert and oriented a person is. A decreased level of consciousness can be caused by low blood oxygen levels (hypoxemia), high carbon dioxide levels (hypercapnia), or acid-base imbalance, which can affect brain function and mental status.
Choice e) is correct because hypotension is a common manifestation of ARF. Hypotension is a condition in which the blood pressure is lower than normal. Hypotension can be caused by low blood oxygen levels (hypoxemia), which can impair heart function and reduce cardiac output.

Correct Answer is C
Explanation
Choice A: Removing the elastic bandages is not recommended. These bandages help slow the spread of venom by compressing the lymphatic vessels. Removing them could worsen the envenomation.
Choice B: This is incorrect. The nurse should not discharge the client, as they may develop serious complications from the snake bite, such as swelling, bleeding, infection, or shock. The client should be monitored closely and treated accordingly.
Choice C: This is the correct action. Antivenom treatment is crucial for serious snake envenomation. The sooner it can be administered, the better the outcome.
Choice D: While pain management is important, it is not the priority in this situation. Antivenom takes precedence over pain medication.
Correct Answer is C
Explanation
Choice A Reason: This is incorrect because shortening of P-wave duration is not a sign of hyperkalemia or its reversal.
P-wave duration reflects the time it takes for the atria to depolarize and contract.
Choice B Reason: This is incorrect because restoration of QRS complex amplitude is not a sign of hyperkalemia or its reversal. QRS complex amplitude reflects the voltage or strength of the ventricular depolarization and contraction.
Choice C Reason: This is correct because the reduction of T-wave amplitude is a sign of hyperkalemia reversal. T-wave amplitude reflects the repolarization or recovery of the ventricles after contraction. Polystyrene sulfonate is a medication that lowers the serum potassium level by binding to it in the gastrointestinal tract and excreting it in the stool. High serum potassium level, or hyperkalemia, can cause cardiac arrhythmias and ECG changes, such as peaked T waves, prolonged PR interval, flatened P waves, widened QRS complex, and ventricular fibrillation. By lowering the serum potassium level, polystyrene sulfonate can reverse these ECG changes and normalize the cardiac rhythm.
Choice D Reason: This is incorrect because the widening of the QRS complex is a sign of hyperkalemia, not its reversal. Widening of the QRS complex reflects the delay or impairment of ventricular depolarization and contraction.
