Clinical Case Scenario Assignment -

Unit Learning Outcomes -

1 - Explain the importance of homeostasis in maintaining health.

2 - Identify the structure and function of bacterial, viral and human cells and tissues.

3 - Describe the structure and function of the integumentary, cardiac, pulmonary, haematological, musculoskeletal, neurological, and endocrine systems.

4 - Identify physiology underpinning vital sign measurement in the identification of normal body systems.

Course Learning Outcome -

1 - Apply broad health knowledge to a range of theoretical and practical nursing situations.

Questions -

Q1. A doctor tells the nursing and midwifery students that it is important to monitor patients' blood pressure when they are receiving Verapamil (a calcium channel blocker). Explain why, with reference to the physiology of cardiac and smooth muscle.

Q2. Communication between cells is key to organism-level regulation of the internal environment to maintain health, that is, nearly constant internal conditions (homeostasis). Outline and compare the intercellular communication pathways that function to provide homeostasis.

Q3. During exercise, the blood flow to the active skeletal muscles is increased by autoregulation. Explain how this works and explain what other controls operate on blood flow.

Q4. A patient's wound overwhelms the clotting mechanism and leads to serious haemorrhage and drop in blood pressure. Explain the compensations that the body has to maintain cardiac output.

Q5. You see a patient with a goiter. You run some tests and find the patient is iodine deficient. Explain how iodine is used in the production of thyroid hormones. Also, explain how a goiter might form as a result of iodine deficiency (be sure to include the role of TSH in your response).

Q6. When patients who are receiving glucocorticoid therapy need to stop taking it (e.g., Prednisone), the doctor will prescribe a series of doses of tapering size to gradually lower the dose rather than suddenly stop it. Explain this dosage strategy in terms of the negative feedback control of cortisol secretion.

Q7. What does it mean to say that the pancreas is both an endocrine and an exocrine organ? Consider the cells involved and the secretion pathways.

Q8. Explain how skin helps to thermally regulate body temperature (be sure to discuss the entire homeostatic feedback mechanism).

Q9. Explain what dual innervation means with regard to the autonomic nervous system. Using the cardiovascular and respiratory systems as examples, explain how dual innervation regulates the function of each system.

Q10. A newborn infant is found dead, abandoned by the road. Among the many questions that the police would like answered is whether the infant was stillborn. Explain how the medical examiner could determine this with reference to the respiratory system and the tests involved.

Your work should include the following:

• Descriptive title.
• Subheadings to identify each case scenario.
• References (both in-text and end-text).
• Do NOT change the order of the case study scenarios.
