A patient has been prescribed antihypertensives. After assessment and analysis, the nurse has identified a nursing diagnosis of risk for ineffective health maintenance related to nonadherence to therapeutic regimen. When planning this patients care, what desired outcome should the nurse identify?
- A. Patient takes medication as prescribed and reports any adverse effects
- B. Patients BP remains consistently below 140/90 mm Hg
- C. Patient denies signs and symptoms of hypertensive urgency
- D. Patient is able to describe modifiable risk factors for hypertension
Correct Answer: A
Rationale: The most appropriate expected outcome for a patient who is given the nursing diagnosis of risk for ineffective health maintenance is that he or she takes the medication as prescribed. The other listed goals are valid aspects of care, but none directly relates to the patients role in his or her treatment regimen.

A student nurse is taking care of an elderly patient with hypertension during a clinical experience. The instructor asks the student about the relationships between BP and age. What would be the best answer by the student?
- A. Because of reduced smooth muscle tone in blood vessels, blood pressure tends to go down with age, not up
- B. Decreases in the strength of arteries and the presence of venous insufficiency cause hypertension in the elderly
- C. Structural and functional changes in the cardiovascular system that occur with age contribute to increases in blood pressure
- D. The neurologic system of older adults is less efficient at monitoring and regulating blood pressure
Correct Answer: C
Rationale: Structural and functional changes in the heart and blood vessels contribute to increases in BP that occur with aging. Venous insufficiency does not cause hypertension, however. Increased BP is not primarily a result of neurologic changes.
The nurse is screening a number of adults for hypertension. What range of blood pressure is considered normal?
- A. Less than 140/90 mm Hg
- B. Less than 130/90 mm Hg
- C. Less than 129/89 mm Hg
- D. Less than 120/80 mm Hg
Correct Answer: D
Rationale: JNC 7 defines a blood pressure of less than 120/80 mm Hg as normal, 120 to 129/80 to 89 mm Hg as prehypertension, and 140/90 mm Hg or higher as hypertension.
A patient in hypertensive urgency is admitted to the hospital. The nurse should be aware of what goal of treatment for a patient in hypertensive urgency?
- A. Normalizing BP within 2 hours
- B. Obtaining a BP of less than 110/70 mm Hg within 36 hours
- C. Obtaining a BP of less than 120/80 mm Hg within 36 hours
- D. Normalizing BP within 24 to 48 hours
Correct Answer: D
Rationale: In cases of hypertensive urgency, oral agents can be administered with the goal of normalizing BP within 24 to 48 hours. For patients with this health problem, a BP of 120/80 mm Hg may be unrealistic.
A patient newly diagnosed with hypertension asks the nurse what happens when uncontrolled hypertension is prolonged. The nurse explains that a patient with prolonged, uncontrolled hypertension is at risk for developing what health problem?
- A. Renal failure
- B. Right ventricular hypertrophy
- C. Glaucoma
- D. Anemia
Correct Answer: A
Rationale: When uncontrolled hypertension is prolonged, it can result in renal failure, myocardial infarction, stroke, impaired vision, left ventricular hypertrophy, and cardiac failure. Glaucoma and anemia are not directly associated with hypertension.
A patient with primary hypertension complains of dizziness with ambulation. The patient is currently on an alpha-adrenergic blocker and the nurse assesses characteristic signs and symptoms of postural hypotension. When teaching this patient about risks associated with postural hypotension, what should the nurse emphasize?
- A. Rising slowly from a lying or sitting position
- B. Increasing fluids to maintain BP
- C. Stopping medication if dizziness persists
- D. Taking medication first thing in the morning
Correct Answer: A
Rationale: Patients who experience postural hypotension should be taught to rise slowly from a lying or sitting position and use a cane or walker if necessary for safety. It is not necessary to teach these patients about increasing fluids or taking medication in the morning (this would increase the effects of dizziness). Patient should not be taught to stop the medication if dizziness persists because this is unsafe and beyond the nurses scope of practice.
