Answer:
The answer to the question: The nephron uses counter-current exchange between the Loop of Henle and peritubular capillaries to reabsorb glucose back into the blood as this is why glucose should not be found in the urine:___, is, false.
Explanation:
The process of urine processing as filtrate goes through a nephron´s different portions, is pretty complex, but fascinating. Initially, water, certain substances as glucose, sodium, and others, pass through the glomerulus intoo the PCT (Proximal convoluted tubule) where the initial filtrate is formed. This filtrate will then move through other portions to be added to, and substracted from, on different elements, until finally, at the very end, urine is produced. However, one molecule that is reabsorbed early in this process of filtrate production, is glucose. Glucose should not be usually present in urine, unless there has been a huge consumption of it and transporters in the PCT cannot deal with the amount being filtered, or there is a condition like diabetes mellitus. It is in the PCT that glucose reabsorption is done, together with sodium ions. This is why the answer to the statement is false.
Below are the data of the client grouped under objective and subjective data
OBJECTIVE DATA

NURSING DIAGNOSIS
1, Constipation related to lack of activity/sedentary lifestyle.
2, Anxiety related to disease condition evidenced by client speaking rapidly and loudly.(aggressive)
Answer:
The correct answer is B. Proximal
Explanation:
Tooth have five surfaces distal, facial, Incisal, Lingual and mesial. Mesial surface is the tooth surface which is present towards the front portion and lingual surface towards back portion of mouth.
So the area where mesial surface of one tooth touches the lingual surface of another tooth is called proximal surface. There is a point where the two teeth that are adjacent touches each other called contact point of proximal surface. It becomes wider due to chewing and grinding with time.
Answer:
The correct option is d. All of the above contribute to the pinal gland being called the body's timekeeper.
Explanation:
The pineal gland is a reddish-grey pine-cone shape gland present in the brain. It is responsible for the production of melatonin. The melatonin is a hormone which controls the body's sleep cycle and the circadian rhythm.
The melatonin production is stimulated by darkness. Therefore, the melatonin levels are low during the days and increases at night. This helps in regulating the body's sleep cycle and the circadian rhythm.
Thus, the pineal gland is referred to as the body's timekeeper.
Answer:
True
Explanation:
Pacemaker cells, unlike other neurons in the body, can depolarized themselves (and therefore can fire action potentials) without the need of an external innervation of the autonomic nervous system.
Each class of pacemaker cells has its own intrinsic rate.
For example, sinoatrial node rate is 60-100 bpm (the normal heart frequency).
The atrioventricular node is also part of the electrical conduction system of the heart. When the sinoatrial node fails, atrioventricular node takes the lead (40-60 bpm).
