Which of the following is true regarding the physiology of an open pneumothorax?

Air cannot pass freely into the thoracic cavity through a chest wound.

The air is trapped when it enters the cavity.

Air moves in and out of a wound in the chest wall.

There are no audible sounds in an open pneumothorax.

Answer and Explanation

The Correct Answer is C

Choice A Reason:

Air cannot pass freely into the thoracic cavity through a chest wound is incorrect because air can indeed pass freely into the thoracic cavity through the chest wound in an open pneumothorax.

Choice B Reason:

The air is trapped when it enters the cavity is incorrect because the characteristic feature of an open pneumothorax is that air is not trapped; rather, it enters the thoracic cavity with each inhalation and exits with each exhalation through the chest wound.

Choice C Reason:

Air moves in and out of a wound in the chest wall is correct. In an open pneumothorax, also known as a "sucking chest wound," air can freely move in and out of the thoracic cavity through a wound in the chest wall. This occurs due to the creation of a communication pathway between the external environment and the pleural space, typically caused by a penetrating injury to the chest.

Choice D Reason:

There are no audible sounds in an open pneumothorax is incorrect because in an open pneumothorax, there may be audible sounds associated with the movement of air in and out of the wound, such as a sucking or bubbling sound, depending on the size and location of the wound. These sounds can be clinically significant and aid in the diagnosis of an open pneumothorax.

Correct Answer is ["A","B","D"]

Explanation

Choice A Reason:

"Have you had any nausea and vomiting with your headache?": This question is appropriate. Nausea and vomiting are common symptoms associated with migraines. Asking about these symptoms can help confirm the diagnosis of a migraine headache.

Choice B Reason:

"Are you bothered by the lights in here?" This question is appropriate. Sensitivity to light, known as photophobia, is a classic symptom of migraines. Inquiring about light sensitivity can provide additional evidence for the diagnosis.

Choice C Reason:

"Have you noticed any confused or cloudy thinking?". This question is inappropriate. Confusion or cognitive symptoms are not typical of migraines. However, some individuals may experience difficulty concentrating or cognitive symptoms during a migraine aura. This question may help assess for aura symptoms.

Choice D Reason
Have you experienced or are you experiencing any strange smells?" This question is appropriate. Some individuals may experience olfactory hallucinations or sensitivity to odors during a migraine aura. Asking about strange smells can help identify possible aura symptoms.

Choice E Reason:

"Did you feel weak before the headache started or do you feel weak now?" This question is inappropriate. While weakness is not a typical symptom of migraines, some individuals may experience fatigue or muscle weakness during a migraine attack. This question may help assess the overall impact of the headache on the client.

A. Dulaglutide B. Montelukast sodium C. Glatiramer acetate D. Oxybutynin

Correct Answer is D

Explanation

Choice A Reason:

Dulaglutide is inappropriate. Dulaglutide is a medication used to treat type 2 diabetes by improving blood sugar control. It is not indicated for the management of neurogenic bladder or urinary incontinence.

Choice B Reason:

Montelukast sodium is inappropriate. Montelukast sodium is a medication primarily used to treat asthma and allergic rhinitis by blocking leukotrienes, which are inflammatory substances that contribute to asthma and allergy symptoms. It is not indicated for the management of neurogenic bladder or urinary incontinence.

Choice C Reason:

Glatiramer acetate is inappropriate. Glatiramer acetate is a medication used to treat relapsing-remitting multiple sclerosis (MS) by modulating the immune system. It is not indicated for the management of neurogenic bladder or urinary incontinence.

Choice D Reason:

Oxybutynin is appropriate. Oxybutynin is a medication commonly prescribed for the management of neurogenic bladder and urinary incontinence. It belongs to a class of medications called anticholinergics, which work by relaxing the bladder muscles and reducing bladder spasms. Oxybutynin helps control urinary urgency, frequency, and incontinence associated with neurogenic bladder, including spasm-induced incontinence.
