Chapter 27 : Caring for Clients With Hypertension Questions
Question 1 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 2 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 3 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 4 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.
Question 5 of 5
The nurse obtains a blood pressure of $136 / 86 \mathrm{~mm} \mathrm{Hg}$ on a morning assessment of a client with history of hypertension. Which pressure is of most concern when considering ventricular relaxation?
Correct Answer: C
Rationale: Diastolic blood pressure reflects arterial pressure during ventricular relaxation. It depends on the resistance of the arterioles and the diastolic filing times. Central aortic pressure is the blood pressure pumped from the left ventricle and measured at the root of the aorta. Systolic blood pressure is determined by the force and volume of blood that the left ventricle ejects. Central venous pressure reflects the blood pressure returning to the heart.
