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.)
Hypotension
Decreased level of consciousness
Severe dyspnea
Headache
Nausea
Correct Answer : B,C
Choice A reason: Hypotension is not a common manifestation of ARF. Hypotension is a low blood pressure, defined as less than 90/60 mm Hg. Hypotension can have many causes, such as dehydration, blood loss, heart problems, or medications. ARF does not directly cause hypotension, but it can lead to complications such as shock or organ failure, which can lower the blood pressure.
Choice B reason: Decreased level of consciousness is a frequent manifestation of ARF. Decreased level of consciousness is a state of impaired awareness, orientation, memory, or judgment. Decreased level of consciousness can occur in ARF due to several factors, such as hypoxia, hypercapnia, acidosis, or infection. The nurse should monitor the mental status of the client with ARF and report any changes to the provider.
Choice C reason: Severe dyspnea is a common manifestation of ARF. Dyspnea is a subjective sensation of difficulty breathing or shortness of breath. Severe dyspnea can occur in ARF due to the reduced oxygen delivery or increased carbon dioxide retention in the blood. The nurse should assess the respiratory rate, rhythm, depth, and effort of the client with ARF and provide oxygen therapy as prescribed.
Choice D reason: Headache is not a typical manifestation of ARF. Headache is a pain or discomfort in the head, scalp, or neck. Headache can have many causes, such as stress, dehydration, sinusitis, or migraine. ARF does not directly cause headache, but it can cause increased intracranial pressure or cerebral edema, which can trigger headache.
Choice E reason: Nausea is not a usual manifestation of ARF. Nausea is a feeling of sickness or discomfort in the stomach that can lead to vomiting. Nausea can have many causes, such as food poisoning, motion sickness, pregnancy, or medications. ARF does not directly cause nausea, but it can cause gastrointestinal bleeding or hepatic encephalopathy, which can induce nausea.

Correct Answer is C
Explanation
Choice A reason: Flexing the upper and extending the lower extremities in response to the painful stimulus is not an expected response for a client who has a traumatic head injury. This is a sign of decorticate posturing, which indicates damage to the cerebral hemispheres or the internal capsule. Decorticate posturing is a type of abnormal flexion that involves the abduction of the arms, internal rotation of the shoulders, flexion of the wrists, and extension of the legs.
Choice B reason: Pushing the painful stimulus away is not an expected response for a client who has a traumatic head injury. This is a sign of normal motor function, which indicates that the client can localize and withdraw from the painful stimulus. This is the highest level of motor response on the Glasgow Coma Scale (GCS), which is a neurological scoring system used to assess conscious level after head injury.
Choice C reason: Extending the body toward the painful stimulus is an expected response for a client who has a traumatic head injury. This is a sign of decerebrate posturing, which indicates damage to the brainstem or midbrain. Decerebrate posturing is a type of abnormal extension that involves the abduction of the arms, external rotation of the shoulders, extension of the wrists, and extension of the legs.
Choice D reason: Showing no reaction to the painful stimulus is not an expected response for a client who has a traumatic head injury. This is a sign of flaccid paralysis, which indicates damage to the spinal cord or peripheral nerves. Flaccid paralysis is a type of complete loss of muscle tone and reflexes that involves the absence of any voluntary or involuntary movements.
Correct Answer is D
Explanation
Choice A reason: Overflow incontinence is not the type of urinary incontinence that the client is experiencing. Overflow incontinence occurs when the bladder is overfilled and cannot empty properly, causing frequent or constant dribbling of urine. It can be caused by a blockage in the urinary tract, such as an enlarged prostate or a kidney stone, or by a weak bladder muscle that cannot contract enough to empty the bladder.
Choice B reason: Urge incontinence is not the type of urinary incontinence that the client is experiencing. Urge incontinence occurs when the bladder muscle contracts involuntarily and causes a sudden and strong urge to urinate, followed by an involuntary loss of urine. It can be caused by an infection, a neurological disorder, or an overactive bladder.
Choice C reason: Stress incontinence is not the type of urinary incontinence that the client is experiencing. Stress incontinence occurs when the pelvic floor muscles or the urethral sphincter are weakened or damaged and cannot hold urine in the bladder when there is increased abdominal pressure, such as from coughing, sneezing, laughing, or exercising. It can be caused by pregnancy, childbirth, menopause, or surgery.
Choice D reason: Reflex incontinence is the type of urinary incontinence that the client is experiencing. Reflex incontinence occurs when the bladder muscle contracts without the sensation or control of the person, causing urine to leak without warning or awareness. It can be caused by nerve damage that affects the communication between the bladder and the brain, such as from a spinal cord injury, a stroke, or multiple sclerosis..
