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 ["A","C","D"]
Explanation
Choice A Reason: This is correct because smallpox is a highly contagious and deadly viral disease that can be used as a biological weapon. Smallpox was eradicated in 1980, but some samples of the virus are still stored in laboratories. If released intentionally, smallpox could cause a global pandemic.
Choice B Reason: This is incorrect because hydrogen cyanide is a chemical weapon of mass destruction, not a biological one. Hydrogen cyanide is a colorless gas that interferes with cellular respiration and causes rapid death.
Choice C Reason: This is correct because botulism is a serious and potentially fatal illness caused by a toxin produced by the bacterium Clostridium botulinum. Botulism can be used as a biological weapon by contaminating food or water supplies or by aerosolizing the toxin.
Choice D Reason: This is correct because anthrax is an infection caused by the spore-forming bacterium Bacillus anthracis. Anthrax can be used as a biological weapon by releasing the spores into the air or by contaminating food or water sources.
Choice E Reason: This is incorrect because sarin is a chemical weapon of mass destruction, not a biological one. Sarin is a nerve agent that blocks the transmission of nerve impulses and causes respiratory failure and death.
Correct Answer is A
Explanation
The correct answer is: A. Elective cardioversion
Choice A reason:
Elective cardioversion is a medical procedure that is used to restore a normal heart rhythm in patients experiencing certain types of arrhythmias, including ventricular tachycardia (VT), when they are stable. It involves the delivery of a controlled electric shock to the heart, which is synchronized with the heart's electrical activity to convert the abnormal rhythm back to a normal sinus rhythm. This procedure is typically performed when VT is not causing hemodynamic instability and the patient is not in immediate danger.
Choice B reason:
Defibrillation is an emergency treatment for life-threatening cardiac arrhythmias, particularly ventricular fibrillation (VF) or pulseless ventricular tachycardia. It involves delivering a high-energy electric shock to the heart unsynchronized to the heart's electrical cycle, aiming to reset the heart's electrical state and allow it to reestablish an effective rhythm. In the scenario provided, where the patient is experiencing VT but not VF, defibrillation would not be the first line of action unless the VT deteriorates into VF or the patient becomes pulseless.
Choice C reason:
CPR, or cardiopulmonary resuscitation, is a lifesaving technique useful in many emergencies, including heart attack or near drowning, in which someone's breathing or heartbeat has stopped. In the case of VT, if the patient is conscious and has a pulse, CPR is not indicated. CPR would only be necessary if the patient's heart stops beating (cardiac arrest) as a result of the VT.
Choice D reason:
Radiofrequency catheter ablation is a procedure used to treat some types of arrhythmias, including VT, by destroying the area of heart tissue that is causing the abnormal heart rhythm. This treatment is generally considered when medication is ineffective or not tolerated, or in recurrent VT. It is not typically the first line of treatment in an acute setting where the patient is stable and experiencing VT.
