A client with cancer is diagnosed with typhitis. which emergency intervention would the nurse perform?
Gnesinka [82]
Typhitis, also called neutropenic enterocolitis, is an infection that often develops in cancer patients who undergo chemotherapy. In many cases, surgical intervention is required.

Without surgical intervention, the patient would be transferred to an ICU (Intensive Care Unit) for monitoring, and the nurse would perform some or all of these emergency actions:
1. Bowel rest and nasogastric suction,
2. Serial abdominal examinations,
3. Providing intravenous fluids, blood, and platelet transfusions when needed,
4. Using antibiotics to fight the infection, and obtaining cultures to determine if the antibiotic is working,
5. Not administering medication that could worsen the situation.

gHow would an inhibitor of cAMP phosphodiesterase affect glucose mobilization in muscle? It would reduce cAMP levels and inhibit
Ksivusya [100]
<h2>cAMP and glucose mobilization</h2>

Explanation:

It would maintain high cAMP level and elevate glucose mobilization

  • Phosphodiesterase is an effector enzyme which degrades secondary messenger cAMP(cyclic adenosine monophosphate)
  • Here in this case an inhibitor is inhibiting the phosphodiesterase therefore cAMP level will increase
  • As cAMP level rise it activates a protein called protein kinase A which phosphorylates phosphorylase kinase and activates it
  • Phosphorylase kinase becomes active that phosphorylates glycogen phosphorylase and makes it active,glycogen phosphorylase catalyse breakdown of glycogen(in liver and muscle cells)
  • In liver cells breakdown of glycogen occurs and glucose 1 phosphate gets converted into glucose and supplied to whole body through blood
