Chapter 27 : Caring for Clients With Hypertension Questions
Question 1 of 5
The nurse is teaching a health class at the local community center. What body system would the nurse explain regulates arterial blood pressure?
Correct Answer: D
Rationale: The autonomic nervous system, the kidneys, and various endocrine glands regulate arterial pressure. The cardiovascular system, immune system, and lymphatic systems do not regulate arterial blood pressure.
Question 2 of 5
The nurse in an oncology clinic notes that the client being treated has hypertension. What tumor is a predisposing condition for secondary hypertension?
Correct Answer: A
Rationale: Predisposing conditions include kidney disease, pheochromocytoma (a tumor of the adrenal medulla), hyperaldosteronism (increased secretion of mineralocorticoid by the adrenal cortex), atherosclerosis, use of cocaine or other cardiac stimulants (e.g., weight-control drugs, caffeine), and use of oral contraceptives. Wilms' tumors, astrocytomas, and lymphomas are not predisposing conditions for secondary hypertension.
Question 3 of 5
The nurse is caring for a client diagnosed with secondary hypertension. What would be a predisposing condition for this diagnosis?
Correct Answer: D
Rationale: Predisposing conditions include kidney disease, pheochromocytoma (a tumor of the adrenal medulla), hyperaldosteronism (increased secretion of mineralocorticoid by the adrenal cortex), atherosclerosis, use of cocaine or other cardiac stimulants (e.g., weight-control drugs, caffeine), and use of oral contraceptives. Secondary hypertension is not caused by the use of sedatives, hypoaldosteronism, or pancreatic disease.
Question 4 of 5
The nurse is creating a community teaching demonstration focusing on the cause of blood pressure. When completing the visual aid, which body structures represent the mechanism of blood pressure?
Correct Answer: B
Rationale: Blood pressure is the force produced by the volume of the blood in arterial walls. It is represented by the formula: BP- CO (cardiac output) PR (peripheral resistance).
To highlight the mechanism of cardiac output, a heart would be on the visual aid and blood vessels.
Question 5 of 5
The nurse is caring for a client who is newly diagnosed with hypertension. The client states, 'I do not understand what is causing my blood pressure to continue to rise.' Which information does the nurse recognize as the key structure in regulating arterial blood pressure?
Correct Answer: D
Rationale: The body regulates blood pressure throughout the day. The components of the autonomic nervous system, the kidneys, and endocrine glands regulate arterial pressure. The heart is the pump sending blood throughout the system. The lungs exchange oxygen but do not affect blood pressure. The brain recognizes and processes sympathetic nervous system activity to raise blood pressure.
