A nurse is caring for a group of clients in a medical unit. Which of the following clients is at the highest risk for developing osmotic cerebral edema?
A client with a decreased potassium level
A client with a decreased serum glucose
A client with an increased hemoglobin A1C
A client with an increased creatinine level
None
None
The Correct Answer is B
Choice A Reason:
A client with a decreased potassium level is incorrect. Hypokalemia (decreased potassium level) can cause various neurological symptoms, but it doesn't directly lead to osmotic cerebral edema.
Choice B Reason:
When plasma glucose levels are rapidly lowered, an osmotic gradient develops between the brain and plasma, which can lead to cerebral edema. Brain cells pull water from the plasma, resulting in widespread edema.
Choice C Reason:
While HbA1c is an important marker of diabetes control and may indicate poor long-term management, it does not directly relate to the acute metabolic derangements (e.g., rapid osmotic shifts, severity of acidosis) that predispose to cerebral edema in DKA.
Choice D Reason:
A client with an increased creatinine level is incorrect. Elevated creatinine levels typically indicate kidney dysfunction or dehydration, but they don't directly cause osmotic cerebral edema.

Correct Answer is D
Explanation
Choice A Reason:
Depression is incorrect. While depression can contribute to headaches in some individuals, it is more commonly associated with migraine headaches rather than tension-type headaches or cluster headaches. People with depression may experience changes in neurotransmitter levels and alterations in pain perception, which can exacerbate migraines. However, tension-type headaches and cluster headaches are generally less strongly associated with depression as a precipitating factor compared to migraines.
Choice B Reason:
Smoking is incorrect. Smoking can be a trigger for headaches in some individuals, particularly migraines, due to the vasoconstrictive effects of nicotine and other compounds in tobacco smoke. However, smoking is not universally recognized as a common precipitating factor for tension-type headaches or cluster headaches. While individuals with cluster headaches may have higher rates of smoking compared to the general population, it is not a factor commonly shared with tension-type headaches.
Choice C Reason:
Poor posture is incorrect. Poor posture can contribute to muscle tension and cervical spine strain, which may trigger tension-type headaches. However, poor posture is not typically considered a precipitating factor specific to cluster headaches. While tension-type headaches may be exacerbated by poor posture, cluster headaches are characterized by severe, unilateral pain typically centered around the eye or temple, with associated autonomic symptoms such as tearing, nasal congestion, or ptosis.
Choice D Reason:
Stress is correct. Stress is a well-established precipitating factor for both tension-type headaches and cluster headaches. Stress can lead to muscle tension and contraction, which are common triggers for tension-type headaches. Additionally, stress can also contribute to the onset or worsening of cluster headaches, although the exact mechanisms underlying this association are not fully understood. Therefore, stress is a common precipitating factor for both tension-type headaches and cluster headaches.
Correct Answer is ["A","B","C","D"]
Explanation
Choice A Reason:
Chronic cough is correct. Persistent cough is a common symptom of COPD, often occurring due to irritation and inflammation in the airways.
Choice B Reason:
Sputum production is correct. COPD patients frequently experience increased mucus production, leading to coughing up phlegm or sputum, especially in the morning.
Choice C Reason:
Dyspnea is correct. Shortness of breath or dyspnea is a hallmark symptom of COPD, particularly during physical activity or exertion, and it tends to worsen as the disease progresses.
Choice D Reason:
Wheezing occurs due to narrowed airways and increased airway resistance. It is more noticeable during expiration but can also be present during inspiration in severe cases.
Choice E Reason:
Chest tightness is incorrect. While chest tightness can occur in COPD, it is typically more associated with asthma. However, some individuals with COPD may experience chest tightness, especially during exacerbations or when airflow is significantly limited.
