Which of the following can be considered as a clinical use of nicotinic antagonists? Used clinically in surgical operation causing skeletal muscles relaxation Used clinically in surgical operation causing smooth muscles relaxation All the answers are correct Used clinically in surgical operation causing cardiac muscle relaxation
Norepinephrine acts on heart muscle cells by: Group of answer choices blocking the action of calcium. increasing heart contractility. causing a decrease in stroke volume. causing threshold to be reached more quickly. more than one of the above.
Activation of α-adrenergic receptors in vascular smooth muscle stimulates (vasodilation or vasoconstriction). Give an example of an organ system where this occurs.
The autonomic nervous system can change the rate of the heart by: can choose more than one Group of answer choices - beta1 adrenergic receptor activation. Increases in cAMP lead to increased amounts of Na+ influx (though If channels) and Ca2+ influx of the pacemaker cells. This increases the frequency of APs of the pacemaker, and increases the rate of contraction. - alpha1 adrenergic receptor activation. - muscarinic ACh receptors activation. Activation leads to reduced activity of Ca2+ channels, and increasing activation of K+ channels, hyperpolarizing cells and reducing the rate of contraction. - beta2 adrenergic receptor activation. Increases in cAMP lead to increased amounts of Na+ influx (though If channels) and Ca2+ influx of the pacemaker cells. This increases the frequency of APs of the pacemaker, and increases the rate of contraction.
Order: Dopamine 5mcg/kg/minute: Pt weight 85kg. Titrate to keep SBP >90 Pharmacy supply 800mg/500mL How many mL/hour will you program the pump for to start the infusion, How will you plan to titrate (how much and how often?)
Which of the following statements best describes the actions of the neurotransmitter noradrenaline in the heart? Noradrenaline acts on α1-adrenoceptors in the sinoatrial node to increase heart rate. Noradrenaline decreases the rate and force of contraction of the heart. Noradrenaline increases the rate, but not the force of contraction of the heart. Noradrenaline acts on β1-adrenoceptors in the sinoatrial node to increase heart rate.
Patients with a history of heart failure often get this history from chronic hypertension. Chronic hypertension leads to a condition called hypertrophic heart disease, or hypertrophic cardiomyopathy. This means that the heart muscle gets bigger, allowing less room for it to fill with blood. If these patients take beta blockers, such as metoprolol, it will benefit them because the heart will not overwork and grow in size. However, if a patient has pulmonary edema, how could the beta blocker make this patient worse?
You are testing a compound as cardioactive drug. You know the compound is an agonist of acetylcholine (ACh) at the relevant ACh receptor (AChR) on sinoatrial (SA) node cells. Briefly describe how the action of the drug likely would affect the electrical signal produced by the SA node cells. In respect of cardiac output, what would you expect to be the effect of this drug?
