Chapter 27 Questions
Question 1 of 5
The nurse is teaching a client about hypertension and the effects on the left ventricle. What diagnostic test will the nurse describe?
Correct Answer: A
Rationale: Echocardiography will reveal an enlarged left ventricle. Fluorescein angiography reveals leaking retinal blood vessels, and a PET scan is used to reveal abnormalities in blood pressure. A CT scan reveals structural abnormalities.
Question 2 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 3 of 5
The nurse is volunteering at a community blood pressure screening. A client, never diagnosed with hypertension, presents with a blood pressure of $158 / 90 \mathrm{~mm} \mathrm{Hg}$. Which assessment question(s) is appropriate for the nurse to ask? Select all that apply.
Correct Answer: A,C
Rationale: At a community blood pressure clinic, the nurse would assess for common factors for a blood pressure to be elevated. Factors that can affect blood pressures readings include smoking or drinking coffee within 30 minutes of the reading. One beer after work should not affect the blood pressure reading, and some individuals may find it relaxing. Social situations are difficult to assess in a community blood pressure clinic.
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 is employed in a physician's office and is caring for a client present for an annual exam. A blood pressure of $124 / 84 \mathrm{~mm} \mathrm{Hg}$ is documented. Following revised guidelines for identifying hypertension, which educational pamphlet is helpful?
Correct Answer: B
Rationale: A blood pressure of $124 / 84 \mathrm{~mm} \mathrm{Hg}$ is now considered to be in the lower range of prehypertension. Knowledge of stress reduction may be helpful in lowering the blood pressure without medication therapy. A blood pressure of $124 / 84 \mathrm{~mm} \mathrm{Hg}$ is not considered a low blood pressure or in need of medication therapy due to hypertension. Diagnostic testing for cardiac functioning is not typical for a client with prehypertension.
