A nurse is caring for a client who has acute respiratory failure (ARF). The nurse should monitor the client for which of the following manifestations of this condition? (Select all that apply.)
Headache
Severe dyspnea
Nausea
Hypotension
Hypotension
Correct Answer : B,D,E
Choice A Reason: This choice is incorrect because headache is not a common manifestation of ARF. Headache may be caused by various factors such as dehydration, stress, sinusitis, or migraine, but it does not indicate ARF.
Choice B Reason: This choice is correct because severe dyspnea is a common manifestation of ARF. Dyspnea is a difficulty or discomfort in breathing that affects the oxygen delivery and carbon dioxide removal from the body. It may be caused by various factors such as lung disease, heart disease, anemia, or anxiety, but it indicates ARF when it is severe and persistent.
Choice C Reason: This choice is incorrect because nausea is not a common manifestation of ARF. Nausea is a sensation of uneasiness or discomfort in the stomach that may precede vomiting. It may be caused by various factors such as food poisoning, motion sickness, medication side effects, or pregnancy, but it does not indicate ARF.
Choice D Reason: This choice is correct because hypotension is a common manifestation of ARF. Hypotension is a condition in which the blood pressure is lower than normal (less than 90/60 mm Hg). It may be caused by various factors such as dehydration, blood loss, sepsis, or shock, but it indicates ARF when it is due to reduced cardiac output or vasodilation from hypoxia.
Choice E Reason: This choice is correct because decreased level of consciousness is a common manifestation of ARF. Decreased level of consciousness is a condition in which the person has impaired awareness or responsiveness to stimuli. It may be caused by various factors such as brain injury, stroke, seizure, or drug overdose, but it indicates ARF when it is due to increased carbon dioxide levels (hypercapnia) or decreased oxygen levels (hypoxemia) in the brain.

Correct Answer is D
Explanation
Choice A Reason: This is incorrect because administering a nitrate antihypertensive is not the first action, as it may cause a rapid drop in blood pressure and worsen the client's condition.
Choice B Reason: This is incorrect because obtaining the client's heart rate is not the first action, as it does not address the cause of autonomic dysreflexia or relieve the symptoms.
Choice C Reason: This is incorrect because assessing the client for bladder distention is not the first action, as it may take time and delay the treatment of autonomic dysreflexia.
Choice D Reason: This is correct because placing the client in a high-Fowler's position is the first action, as it lowers the blood pressure by promoting venous return and reducing cardiac preload.
Correct Answer is A
Explanation
Choice A Reason: Dobutamine is a positive inotropic agent that increases the contractility of the heart and improves cardiac output. This leads to increased renal perfusion and urine output, which reduces the fluid overload and edema associated with heart failure. Therefore, this choice is correct.
Choice B Reason: Dobutamine does not have a direct effect on blood glucose level. It may cause hyperglycemia as a side effect, but this is not an indication of its effectiveness. Therefore, this choice is incorrect.
Choice C Reason: Dobutamine may cause a slight decrease in blood pressure due to vasodilation, but this is not its main therapeutic effect. A significant decrease in blood pressure may indicate hypovolemia, hypotension, or shock, which are adverse effects of dobutamine. Therefore, this choice is incorrect.
Choice D Reason: Dobutamine also has a positive chronotropic effect, which means it increases the heart rate. However, this is not a desired outcome for a client with heart failure, as it increases the oxygen demand of the heart and may worsen the condition. Therefore, this choice is incorrect.
