A nurse is teaching a newly licensed nurse about orthostatic hypotension. Which of the following information should the nurse include?
Orthostatic hypotension is indicated by a decrease in diastolic blood pressure of 5 mm Hg.
Orthostatic hypotension is indicated by a decrease in systolic blood pressure of 5 mm Hg.
Orthostatic hypotension increases a client's risk of a fall.
Orthostatic hypotension increases a client's risk of a pulmonary emboli.
The Correct Answer is C
A) Orthostatic hypotension is indicated by a decrease in diastolic blood pressure of 5 mm Hg:
Orthostatic hypotension is typically defined by a decrease in systolic blood pressure of 20 mm Hg or more or a decrease in diastolic blood pressure of 10 mm Hg or more within three minutes of standing up. Diastolic blood pressure alone is not the primary indicator of orthostatic hypotension.
B) Orthostatic hypotension is indicated by a decrease in systolic blood pressure of 5 mm Hg:
While a decrease in systolic blood pressure is a component of orthostatic hypotension, the criterion for diagnosing orthostatic hypotension is a decrease in systolic blood pressure of 20 mm Hg or more or a decrease in diastolic blood pressure of 10 mm Hg or more within three minutes of standing up.
C) Orthostatic hypotension increases a client's risk of a fall:
This statement is correct. Orthostatic hypotension, characterized by a sudden drop in blood pressure upon standing, can lead to dizziness and lightheadedness, increasing the risk of falls, particularly in older adults.
D) Orthostatic hypotension increases a client's risk of a pulmonary emboli:
Orthostatic hypotension is not directly associated with an increased risk of pulmonary emboli. Pulmonary embolism is a separate condition involving a blockage in the pulmonary artery or its branches, typically caused by a blood clot."

Correct Answer is B
Explanation
A) Take this medication with food:
Captopril is an ACE inhibitor, known to work best on an empty stomach. Food can reduce its absorption, impacting its effectiveness. Thus, while clients can take captopril with or without food, it's generally recommended to take it on an empty stomach for optimal results.
B) Monitor for a cough:
Captopril, an ACE inhibitor, commonly induces a persistent, dry cough due to the accumulation of bradykinin. This side effect can be bothersome and may necessitate discontinuation of the medication. Therefore, patients should be vigilant for the onset of a cough and promptly report it to their healthcare provider.
C) Avoid bananas:
Although captopril can occasionally lead to hyperkalemia, advising patients to avoid bananas specifically may not be necessary. While bananas are potassium-rich, restricting them alone might not significantly impact potassium levels. However, patients should be educated on monitoring potassium intake and informed of potential dietary modifications if hyperkalemia occurs.
D) Hold medication for heart rate less than 100/min:
Captopril is not known to directly affect heart rate. This instruction may be more applicable to medications like beta-blockers, which can lower heart rate as part of their mechanism of action. Therefore, holding captopril for heart rates below 100/min may not be clinically indicated.
Correct Answer is C
Explanation
A) Lifestyle modification, including exercise, diet, and decreased smoking and alcohol intake:
This statement is accurate. Lifestyle modifications are essential components of hypertension management and are recommended as the first step in treatment. These modifications include regular physical activity, adopting a heart-healthy diet such as the DASH (Dietary Approaches to Stop Hypertension) diet, reducing sodium intake, limiting alcohol consumption, and quitting smoking. These changes can help lower blood pressure and reduce the risk of cardiovascular events.
B) Use of diuretic, beta-blocker, or ACE inhibitor to supplement lifestyle changes:
This statement is also accurate. If lifestyle modifications alone are insufficient to achieve blood pressure control, pharmacotherapy may be initiated. The choice of antihypertensive medications depends on various factors, including the individual's comorbidities, medication tolerance, and response to treatment. Diuretics, beta-blockers, and ACE inhibitors are commonly used as first-line agents in the management of hypertension, either as monotherapy or in combination with other drugs.
C) All of the above:
This statement is correct. The stepped-care approach to hypertension management involves a combination of lifestyle modifications and pharmacotherapy. Lifestyle changes are typically recommended as the initial step, followed by the addition of antihypertensive medications if necessary to achieve target blood pressure goals. Therefore, both lifestyle modifications and pharmacological interventions are integral components of the stepped-care approach.
D) A combination of antihypertensive drug classes to achieve desired control:
While this statement is true, it does not encompass all aspects of the stepped-care approach. The use of combination therapy with multiple antihypertensive drug classes may be necessary in some cases to achieve optimal blood pressure control. However, it is only one component of the broader treatment strategy, which also includes lifestyle modifications as the foundation of therapy. Therefore, while combination therapy is important, it does not fully represent the stepped-care approach on its own.
