Chapter 27 : Caring for Clients With Hypertension Questions
Question 1 of 5
The nurse would screen a client from which ethnic background for hypertension at an early age?
Correct Answer: D
Rationale: The population of African descent is at the highest risk for development of hypertension. The other ethnic backgrounds have a lower risk.
Question 2 of 5
The nurse is caring for a client with essential hypertension. The nurse reviews lab work and assesses kidney function. Which action of the kidney would the nurse evaluate as the body's attempt to regulate high blood pressure?
Correct Answer: B
Rationale: Hypernatremia (elevated serum sodium level) increases blood volume, which raises blood pressure. The kidney's response to the elevation in blood pressure is to excrete sodium and excess water. Any retention of sodium and water would increase blood volume and, thus, blood pressure. Sodium and water move together.
Question 3 of 5
Which of the following nursing diagnoses is the nurse most correct to choose when caring for a client with long-standing hypertension?
Correct Answer: C
Rationale: The nurse is most correct in choosing Altered Tissue Perfusion for the client with long-standing hypertension. In hypertension, the extra work increases the size of the heart muscle. Eventually, the heart cannot meet the body's metabolic needs limiting the perfusion to the tissues. Impaired Gas Exchange, Activity Intolerance, and a Risk for Decreased Cardiac Output may occur due to the ineffective perfusion.
Question 4 of 5
The nurse is caring for a client with hypertension. The nurse is correct to realize that a 24-hour urine is ordered to determine if the cause of hypertension is related to the dysfunction of what?
Correct Answer: B
Rationale: The 24-hour urine collection specimen is ordered to determine dysfunction of the adrenal gland. The 24-hour urine detects elevated catecholamines. The other options are not evaluated by a 24-hour urine.
Question 5 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.
