Which of the following nursing actions should the nurse take first in order to assist a patient with newly diagnosed stage 1 hypertension in making needed dietary changes?
- A. Have the patient record dietary intake for 3 days.
- B. Give the patient a detailed list of low-sodium foods.
- C. Teach the patient about foods that are high in sodium.
- D. Help the patient make an appointment with a dietitian.
Correct Answer: A
Rationale: The initial nursing action should be assessment of the patient's baseline dietary intake through a 3-day diet history. The other actions may be appropriate, but assessment of the patient's baseline should occur first.

The nurse is assessing a patient who is being investigated for possible white coat hypertension. Which of the following actions should the nurse implement first?
- A. Schedule the patient for frequent BP checks in the clinic.
- B. Instruct the patient about the need to decrease stress levels.
- C. Tell the patient how to self-monitor and record BPs at home.
- D. Teach the patient about ambulatory blood pressure monitoring.
Correct Answer: C
Rationale: Having the patient self-monitor BPs at home will provide a reliable indication about whether the patient has hypertension. Frequent BP checks in the clinic are likely to be high in a patient with white coat hypertension. Ambulatory blood pressure monitoring may be used if the data from self-monitoring is unclear. Although elevated stress levels may contribute to hypertension, instructing the patient about this is unlikely to reduce BP.
The nurse is caring for a patient with hypertension and has just administered the initial dose of labetalol. Which of the following actions should the nurse take?
- A. Encourage oral fluids to prevent dry mouth or dehydration.
- B. Instruct the patient to ask for help if heart palpitations occur.
- C. Ask the patient to request assistance when getting out of bed.
- D. Teach the patient that headaches may occur with this medication.
Correct Answer: C
Rationale: Labetalol decreases sympathetic nervous system activity by blocking both ?±- and β-adrenergic receptors, leading to vasodilation and a decrease in heart rate, which can cause severe orthostatic hypotension. Heart palpitations, dehydration, and headaches are possible adverse effects of other antihypertensives.
The charge nurse observes a new RN doing discharge teaching for a patient who is hypertensive and has a new prescription for enalapril. Which of the following actions by the new RN should cause the charge nurse to intervene in the patient's care?
- A. Check the BP with a home BP monitor every day.
- B. Move slowly when moving from lying to standing.
- C. Increase the dietary intake of high-potassium foods.
- D. Make an appointment with the dietitian for teaching.
Correct Answer: C
Rationale: The ACE inhibitors cause retention of potassium by the kidney, so hyperkalemia is a possible adverse effect. The other teaching by the new RN is appropriate for a patient with newly diagnosed hypertension who has just started therapy with enalapril.
The nurse is caring for a patient who is experiencing a hypertensive crisis and is receiving IV labetalol. Which of the following time frequencies should the nurse assess the patients' blood pressure and pulse during the initial administration of this medication?
- A. 2-3 minutes
- B. 5-10 minutes
- C. 15-30 minutes
- D. Hourly
Correct Answer: A
Rationale: Administered intravenously, the drugs have a rapid (within seconds to minutes) onset of action. The patient's BP and pulse should be taken every 2-3 minutes during the initial administration of these drugs.
The nurse in the emergency department received change-of-shift report on these four patients with hypertension. Which of the following patients should the nurse assess first?
- A. 52-year-old with a BP of 212/90 who has intermittent claudication
- B. 43-year-old with a BP of 190/102 who is complaining of chest pain
- C. 50-year-old with a BP of 210/110 who has a creatinine of 1.33 mcmol/L
- D. 48-year-old with a BP of 200/98 whose urine shows microalbuminuria
Correct Answer: B
Rationale: The patient with chest pain may be experiencing acute myocardial infarction and rapid assessment and intervention is needed. The symptoms of the other patients also show target organ damage, but are not indicative of acute processes.
