QUESTIONS WITH SOLUTIONS
GRADED A+
◍ What are the 3 membrane(cell-surface) receptors?.
Answer: chemically-gated ion channels(ligand-gated ion channels),
enzyme-coupled receptors, and G-protein coupled receptors
◍ Beta Blockers.
Answer: Initial measures for the treatment of angina pectoris do not include
which response below?
◍ What ligands do the 3 membrane receptors use?.
Answer: hydrophilic ligands
◍ What do chemically-gated ion channels do?.
Answer: so when a ligand(neurotransmitter) binds to it they open to let
certain specific ions such as K+, Ca2+, Na+, and Cl- pass through the
membrane
◍ ST segment elevation.
Answer: The classical ECG change with muscle injury in acute myocardial
infarction is:
◍ Give me an example of how chemically gated ion channels work.
Answer: a ligand which acts as a neurotransmitter known as acetylcholine
binds to the chemically-gated ion channel known as acetylcholine receptor.
in this case receptor acts a Na+ channels, allowing Na+ to enter our skeletal
muscle cells and help them contract
◍ What do enzyme-coupled receptors do?.
Answer: they are receptors that have enzymatic activity and act as enzymes
, or associate with enzymes found inside of cells
◍ Give me an example of how enzyme-coupled receptors work.
Answer: a ligand binds to the receptor and causes it to be active which
causes a cellular response and once the ligand unbinds the enzyme-coupled
receptor becomes inactive
◍ CHF.
Answer: Elevated cardiac iso-enzymes generally do not occur in which
response below?
◍ Almost all enzyme-coupled receptors are what?.
Answer: they are protein kinases which phosphorylate themselves or other
proteins
◍ Increased CO.
Answer: The major therapeutic goal in the treatment of cariogenic shock is
to:
◍ Reduces preload and after load and improves contractility.
Answer: You receive orders to start nitroprusside and dobutamine in your
patient with end-stage cardiomyopathy. How will this tx regimen affect CO?
◍ What are receptor tyrosine kinases(RTK's)?.
Answer: they are the most common type of enzyme-coupled receptors
◍ Which processes do RTK's influence?.
Answer: cell cycle, cell metabolism, cell proliferation(division), and cell
migration
◍ Encourage the patient to ventilate his/her concerns.
Answer: In dealing with a depressed pt during the first days post AMI the
most appropriate nursing action would be:
◍ Explain to me how RTK's work.
Answer: So RTK's have both an extracellular ligand-binding domain and an
intracellular kinase domain which contains tyrosine. What happens is a
ligand which is a growth factor or hormone binds to the extracellular side of
, two RTKs. then these two RTK's begin to join together(dimerization) and
when they join together they use ATP to add phosphorus to each other
known as autophosphorylation. then what happens is response protein binds
to the phosphotyrosine on the receptor and that receptor can now
phosphorylate other proteins
◍ change in mental status.
Answer: Mr Seamore is receiving thrombolytics (TPA) 3 hrs after an AMI.
Which of the following would most likely require discontinuing the
infusion?
◍ Pulmonary artery occlusion (wedge).
Answer: The following monitor pattern would indicate that the pulmonary
artery (swan ganz) catheter is in which position?
◍ Aortic stenosis.
Answer: A systolic murmur that is auscultated at the 2nd intercostal space,
right sternal border is called:
◍ High to low.
Answer: Which of the following wave patterns indicates proper functioning
of an arterial line?
◍ What are insulin receptors?.
Answer: type of RTK that are activated by insulin
◍ 8-10 minutes.
Answer: After an arterial catheter is removed, direct pressure should be
applied to the artery for how long?
◍ Right atrium.
Answer: A CVP reading directly reflects pressure in the:
◍ What is insulin?.
Answer: hormone produced by beta cells in the pancreas and they lower
blood glucose levels
◍ Explain to me how the insulin receptor works.
