Question 1 of 5
Peripheral blood flow is dependent on which of the following variables?
Correct Answer: D
Rationale: Peripheral blood flow depends on pressure differences between the arterial and venous systems (driving force) and vascular resistance (opposing force). This relationship is governed by Poiseuille's law and Ohm's law for fluid flow, where flow is proportional to the pressure gradient and inversely proportional to resistance. The other options are incomplete or incorrect combinations of factors.
Question 2 of 5
A client with thyrotoxicosis says to the nurse, 'I am so irritable. I am having problems at work because I lose my temper very easily.' Which of the following responses by the nurse would give the client the most accurate explanation of her behavior?
Correct Answer: B
Rationale: Thyrotoxicosis, due to excess thyroid hormone, increases metabolism and can affect the nervous system, leading to irritability and emotional lability. This explains the client's behavior as a direct result of the disease's impact on thyroid function.
Question 3 of 5
A client who had a left thoracoscopy sustained an injury secondary to the surgery position. The nurse should assess the client for:
Correct Answer: C
Rationale: Thoracoscopy positioning (lateral decubitus) can compress nerves in the arm, causing tingling due to brachial plexus injury. Footdrop or Achilles reflex issues are unrelated to this position.
Question 4 of 5
The nurse explains to the client that a biopsy of the enlarged lymph node is important because, if Hodgkin's disease is present, the histologic examination will reveal which of the following?
Correct Answer: B
Rationale: Hodgkin's disease is diagnosed by the presence of Reed-Sternberg cells, large multinucleated cells, in the lymph node biopsy. Tay-Sachs and Duchenne's cells are unrelated to Hodgkin's.
Question 5 of 5
The client with gastroesophageal reflux disease (GERD) complains of a chronic cough. The nurse understands that in a client with GERD this symptom is indicative of which of the following conditions?
Correct Answer: D
Rationale: A chronic cough in GERD is often due to aspiration of gastric contents into the respiratory tract, irritating the airways. The other options are less directly related to this symptom.
