Kidney disease can cause hypertension by:
Directly signaling the brain stem to increase blood pressure.
Activating the renin-angiotensin mechanism.
Increasing release (excretion) of sodium and water.
Stimulating the secretion of ANP.
The Correct Answer is B
Kidney disease can cause hypertension by activating the renin-angiotensin mechanism.
This mechanism involves the release of renin from the kidneys, which stimulates the production of angiotensin II, a hormone that constricts blood vessels and increases blood pressure.
Choice A is wrong because kidney disease does not directly signal the brain stem to increase blood pressure.
The brain stem regulates blood pressure through the autonomic nervous system, which responds to various stimuli such as stress, pain, or emotions.
Choice C is wrong because kidney disease does not increase the release (excretion) of sodium and water.
On the contrary, kidney disease can impair the ability of the kidneys to filter out excess sodium and water, which can lead to fluid retention and increased blood pressure.
Choice D is wrong because kidney disease does not stimulate the secretion of ANP.
ANP stands for atrial natriuretic peptide, a hormone that is secreted by the heart when it senses high blood pressure.
ANP causes the kidneys to excrete more sodium and water, which lowers blood pressure.

Correct Answer is A
Explanation
The radial artery is one of the major blood-supplying vessels to the forearm and hand.
It can be felt as a pulse near the thumb on the wrist by gently pressing the artery against the underlying bone.
This is the most commonly measured pulse by nurses to assess peripheral pulse characteristics.
Choice B.
Palmar arch arteries are wrong because these are branches of the radial and ulnar arteries that form anastomosis in the palm of the hand.
They are not palpable on the wrist.
Choice C.
The brachial artery is wrong because this is the main artery of the upper arm that bifurcates into the radial and ulnar arteries at the cubital fossa.
It can be felt as a pulse in the antecubital fossa, not near the thumb on the wrist.
Choice D
The Ulnar artery is wrong because this is another major blood-supplying vessel to the forearm and hand that runs along the medial aspect of the forearm.
It can be felt as a pulse on the little finger side of the wrist, not near the thumb.
Correct Answer is D
Explanation
Exocrine glands secrete through ducts or tubes to the body’s exterior.
For example, sweat glands, salivary glands, and liver are exocrine glands.
Choice A is wrong because exocrine glands do not only secrete salts, but also other substances such as enzymes, mucus, and sebum.
Choice B is wrong because exocrine glands do not secrete hormones at all.
Hormones are secreted by endocrine glands, which are ductless glands that release their products directly into the bloodstream.
Choice C is wrong because exocrine glands do not secrete into the bloodstream, but onto an epithelial surface such as the skin or the gastrointestinal tract.
Only endocrine glands secrete into the bloodstream.
