All of the following statements are true EXCEPT that nicotine in cigarette smoke binds to hemoglobin and reduces the amount of o

xygen delivered to fetal tissues. marijuana and cocaine can cross the placenta and enter the fetal bloodstream. below average intellectual function is the most common and most serious effect of fetal alcohol syndrome (FAS). some over the counter drugs pose no risk to the fetus.

Hi !

<em>EXCEPT :</em>

katrin2010 [14]

Answer:

1) eating salty food= c) increases water reabsorption

2) blood loss= a) increases both water and Na+ reabsorption

3) alcohol consumption= a) Increases both water and Na+ reabsorption

4) Aldosterone release= a) Increases both water and Na+ reabsorption

5) Severe diarrhea= a) Increases both water and Na+ reabsorption

6) Sweating=  a) Increases both water and Na+ reabsorption

7)   diabetes insipidus= c) Increases water reabsorption

8)  caffeine consumption= b) does not increase water or Na+ reabsorption.

9) ADH secretion= c) increases water reabsorption

10) dehydration due to inadequate water intake= c) increases water reabsorption.

Explanation:

1) eating salty food

An acute renal Na+ conversion occurs because of eating salty food and is mediated by angiotensin II enzymes and aldosterone. Aldosterone promotes the conversion of sodium in sweating and feces. Increased water intake is also indicative of diluting excess of Na+ also known as dilutional hyponatremia.  

2) blood loss

Blood loss cause release of angiotensin II enzyme which has a vasoconstrictor effect and immediately improves blood pressure. This enzyme causes constriction of both afferent and efferent arterioles in the kidneys and reduces the glomerular filtration rate (GFR). As a result, decrease in fluid loss from kidneys helps in preserving the blood pressure.

3) alcohol consumption

Low sodium blood levels are reported in alcoholic patients due to electrolyte disorder and reset of cerebral osmolarity.

4) Aldosterone release

Aldosterone is also known as the salt-retaining hormone and is released in response to decrease Na+ and increased K+ in plasma. Therefore, Na+ reabsorption by the nephrons is promoted by water retention.

5) severe diarrhea

Severe diarrhea is also managed by secretion of aldosterone from the pituitary gland. This hormone is responsible for increased water and sodium reabsorption from the distal convoluted tubule in the kidneys.

6) sweating

Sweating is responsible for loss of electrolytes i.e. Na+ and Cl. Hence, aldosterone hormone is released which increases the reabsorption of both Na+ and water.

7) diabetes insipidus

People suffering from nephrogenic diabetes insipidus excretes large amount of diluted urine and has severe dehydration. ADH is released to control the excessive urination and reduce hypernatremia.

8) caffeine consumption

Caffeine containing beverages does not cause serious fluid loss or increase Na+ retention. However, they may produce a mild diuretic effect and increase urgency to urinate but does not cause dehydration.

9) ADH secretion

ADH is produced by the hypothalamus in response to increase in blood osmolarity and causes water retention by decreasing urine volume.

10) dehydration due to inadequate water intake

Chronic regulation of increased plasma sodium is performed with release of anti-diuretic hormone (ADH). Na+ imbalance occurs due to abnormal water intake and decrease amount of water is indicative of hypernatremia. Hence, increased thirst mechanism is initiated by ADH and fluid retention is observed.

Answer:

The correct answer would be - the jaw thrust maneuver.

Explanation:

The jaw thrust maneuver is the maneuver that is often used for the patients who are suspected to have a cervical spine injury to prevent obstructing the airway entrance to the trachea in the injured patient.

It is performed by placing middle and index fingers to push the posterior part of the lower jaw physically and the chin is pushed down to open the mouth using thumbs so the mandible gets displace and airway clear by pulling the tongue out.

Thus, the correct answer is - the jaw thrust maneuver.

What is one way to create healthy communication in a marriage?
Anna35 [415]

Answer:

Effective Communication!

  • Be specific
  • Avoid mind reading
  • LISTEN
  • Freely express your emotions
  • Actually talk. The average American couple only spends 20 minutes directly talking to each other every week.

Explanation:

If you're not communicating with your partner, you're ruining your relationship. Talking to each other can get you to understand each other. For example, when you're holding a grudge against something, and don't let your partner know, they're most likely to think you're mad at them. But if you just explain and talk about it, they can help you get through it.
