The nurse is instructing a client who is newly prescribed an antihypertensive medication. Which nursing instruction is emphasized to maintain client safety?
- A. Use a pillbox to store daily medication.
- B. Sit on the edge of the chair and rise slowly.
- C. Do not operate a motor vehicle.
- D. Take the medication at the same time daily.
Correct Answer: B
Rationale: The nursing instruction emphasized to maintain client safety is to sit on the edge of the chair before rising slowly. By doing so, the client reduces the possibility of falls related to postural hypotension. Using a pillbox to store medications and taking the medication at the same time daily is good medication management instruction, but not necessarily related to safety. There is no reason when taking antihypertensive medications to restrict driving.

The nurse is evaluating the types of medications prescribed for a client's hypertension. Which of the following medication classifications establishes an action on vasoconstrictive hormones in the blood stream?
- A. Beta-blocker
- B. ACE inhibitor
- C. Loop diuretic
- D. Calcium channel blocker
Correct Answer: B
Rationale: The angiotensin-converting enzyme (ACE) inhibitor's primary action is to prevent the conversion of angiotensin I to angiotensin II, a potent vasoconstricting hormone in the blood. A beta-blocker blocks the beta-adrenergic receptors decreasing sympathetic nervous system stimulation. Loop diuretics excrete water from the loop of Henle, reducing circulating blood volume. Calcium channel blockers dilate coronary and peripheral arteries.
The nurse is caring for a client who is ordered diazoxide IV to decrease blood pressure. Which nursing consideration is a priority?
- A. Elevate the head of the bed.
- B. Use an automatic blood pressure recording machine.
- C. Place a Foley catheter to monitor urine output.
- D. Assess the client's deep tendon reflex.
Correct Answer: B
Rationale: A nursing priority is to monitor the client's blood pressure every few minutes. It is unrealistic to have the nurse manually assess the blood pressures. An automatic blood pressure machine is programed to assess the blood pressure and record the results for assessment. The other options may be completed; however, monitoring the blood pressure is the priority.
The nurse is teaching a health class at the local community center. What body system would the nurse explain regulates arterial blood pressure?
- A. Cardiovascular system
- B. Immune system
- C. Lymphatic system
- D. Autonomic nervous system
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.
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?
- A. Central aortic pressure
- B. Systolic pressure
- C. Diastolic pressure
- D. Central venous pressure
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.
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?
- A. Heart
- B. Lung
- C. Brain
- D. Kidney
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.
