Assuming that a pregnant woman wants to apply virtue ethics to the dilemma of abortion, what specific character traits/virtues should she emulate and why? What is the source of these specific character traits/virtues? Are they gender specific (i.e., applicable only to women) or they gender neutral (i.e., applying to men as well as women)? Why?

Location: Bristol Unit 0900

Report from previous shift:

Mr. Robert Josh is a 55-year-old native american male who was admitted to our unit at 0700 this morning after being admitted to the ED at 0200 with a diagnosis of dehydration and hypokalemia. Nurse are monitoring his fluid and electrolyte status closely. Nurse have just received admission orders. Two days ago, he developed abdominal cramping, nausea, vomiting, and severe diarrhea 10 hours after eating lunch at a local restaurant. The symptoms have continued for the past 2 days, and food and fluid intake has been minimal to none since the symptoms began. Last night he nearly passed out while going to the bathroom around 0400. Mr. Josh was brought to the ED by his son, and reported dizziness, weakness, and continued nausea. He received 4 mg zofran IV for nausea in the ED. Lab work was drawn and is available in the patient chart, and urine and stool samples have been sent to the lab. Mr. Josh is drowsy but oriented x 3, appears ill, and is irritable. He reports having a headache, which he rates a 3 on a scale of 0–10, but he hasn't wanted anything for it. Admission weight was 72 kg (161 lb), which the patient reports to be about 4.5 kg (10 lb) less than usual. Vital signs were obtained on admission, including orthostatic blood pressure readings. Heart rate is tachycardic and irregular. He has only taken a few ice chips since admission due to his nausea. The patient had one small liquid stool in the ER. He has not voided or experienced emesis since admission. An IV bolus has been completed and now normal saline is running at 155 mL/hr. Mr. Josh has new IV orders that need to be initiated. Nurse will need to start him on oral antibiotics and potassium when nausea resolves. Provide patient education on safety, his prescribed medications, and intake and output measurement

d.) tissue is made up large amount of collagen fibers

d.) it contains more elastic fibers

3.   

Max is a 18 year old college student with insulin-dependent diabetes mellitus (Type 1). Recently, Max has been staying up late to study for final exams. Last night while studying, he shared a full box of cupcakes with his friend. Overnight Max woke up feeling thirsty and in need of urinating. Upon awakening to get ready to take his exam, he tells his friend that he is feeling light headed and his heart is racing. While brushing his hair, he realizes his legs are wobbly; and he panics realizing he forgot to take his insulin yesterday. He calls out to his friend, who finds him in the bathroom unconscious. He is transported by ambulance to the nearby emergency department. Below are the result of his physical and laboratory tests. Physical Exam and Laboratory Values Heart Rate 135 bpm Respirations 32/minute; slow and deep Blood Pressure 90/40 Plasma Levels Glucose 540 mg/dl Na+ 134 mEq/L (normal = 140 mEq/L) K+ 5.8 mEq/L (normal = 4.5 mEq/L) Cl- 96 mEq/L (normal = 105 mEq/L) HCO3- 8 mEq/L (normal = 24 mEq/L) Ketones ++ (elevated) Urine Glucose 4+ (normal = none) Arterial Blood Arterial Blood - PO2 110 Hg (normal = 100 mm Hg) Arterial Blood - PCO2 20 mm Hg (normal = 40 mm Hg) Arterial Blood - pH 7.22 (normal = 7.4)

1. What acid-base disorder does Max have and explain your reasoning? Is it a simple or mixed acid-base disorder? In your answer, discuss the etiology of Max's acid-base disorder.

The following case relates to the next two questions. A 46-year-old man finds that, over a period of time, he has progressive bilateral weakness of both upper and lower limbs beginning with the muscles of the hands. However, testing reveals that sensory functions appear normal. Eventually, this individual is found to have wasting of muscles, fasciculations, and evidence of upper motor neuron (UMN) dysfunction together with an increase in tendon reflexes. After a few additional months, the patient develops facial weakness and an inability to swallow (dysphagia). Further analysis reveals abnormalities in the electromyegram (EMG) of the upper and lower extremities, denervation atrophy. However, the cerebrospinal fluid (CSF) remains normal.

Question 1. This patient is most likely suffering from

1. MS
2. Amyotrophic lateral sclerosis (ALS)
3. Poliomyelitis
4. Myasthenia gravis
5. Cerebral cortical stroke

Question 2. The neuronal regions affected include

1. Dorsal horns of the spinal cord
2. Lateral columns of the spinal cord
3. Ventral horns of the spinal cord
4. Dorsal columns and ventral horns of the spinal cord
5. Ventral horns and lateral horns of the spinal cord

In addition,

1. you should provide the reason of why you made your choice.
2. try to explain the cause of denervation muscle atrophy.
