- A. Increased venous return
- B. Decreased peripheral resistance
- C. Decreased blood volume
- D. Decreased strength and rate of myocardial contractions
- E. Decreased blood viscosity
Correct Answer: B,C,D
Rationale: The medications used for treating hypertension decrease peripheral resistance, blood volume, or the strength and rate of myocardial contraction. Antihypertensive medications do not increase venous return or decrease blood viscosity.

A patient comes to the walk-in clinic complaining of frequent headaches. While assessing the patients vital signs, the nurse notes the BP is 161/101 mm Hg. According to JNC 7, how would this patients BP be defined if a similar reading were obtained at a subsequent office visit?
- A. High normal
- B. Normal
- C. Stage 1 hypertensive

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.

The nurse is teaching a patient about some of the health consequences of uncontrolled hypertension. What health problems should the nurse describe? Select all that apply.
- A. Transient ischemic attacks

- E. Right ventricular hypertrophy
Correct Answer: A,B,C
Rationale: Potential complications of hypertension include the following: left ventricular hypertrophy; MI; heart failure; transient ischemic attacks (TIAs); cerebrovascular accident; renal insufficiency and failure; and retinal hemorrhage. Venous insufficiency and right ventricular hypertrophy are not potential complications of uncontrolled hypertension.
