A nurse is assessing a patient with activity intolerance for possible orthostatic hypotension. Which finding will help confirm orthostatic hypotension?

Blood pressure sitting 140/60; blood pressure 130/60 standing

Blood pressure sitting 130/60; blood pressure 110/60 standing

Blood pressure sitting 126/64; blood pressure 120/58 standing

Blood pressure sitting 130/64; blood pressure 140/70 standing

Answer and Explanation

The Correct Answer is B

A: A drop in systolic blood pressure of 10 mm Hg (from 140 to 130) does not meet the criteria for orthostatic hypotension, which requires a drop of at least 20 mm Hg in systolic pressure or 10 mm Hg in diastolic pressure within three minutes of standing.

B: This finding shows a drop in systolic blood pressure from 130 to 110 mm Hg, which is a 20 mm Hg decrease. This meets the criteria for orthostatic hypotension, indicating that the patient may have this condition.

C: A drop in systolic blood pressure of 6 mm Hg (from 126 to 120) does not meet the criteria for orthostatic hypotension. The decrease is not significant enough to confirm the condition.

D: An increase in blood pressure (from 130/64 to 140/70) does not indicate orthostatic hypotension. This finding suggests that the patient’s blood pressure increases upon standing, which is not consistent with orthostatic hypotension.

Correct Answer is D

Explanation

A: Wearing earphones is not part of the Rinne test. Earphones are used in other types of hearing tests, such as audiometry.

B: A small probe is not used in the Rinne test. Probes are used in other diagnostic procedures, such as tympanometry.

C: Small electrodes are not used in the Rinne test. Electrodes are used in tests like electroencephalography (EEG).

D: A tuning fork is placed on the mastoid bone behind the ear and then near the ear canal during the Rinne test. This test compares air conduction to bone conduction of sound.

A. 165 mg/dL B. 35 mg/dL C. 10 mg/dL D. 31 mg/dL

Correct Answer is B

Explanation

A: A BUN level of 165 mg/dL is extremely high and suggests severe dehydration or possible renal failure. This level is far above the normal range and indicates a critical condition.

B: A BUN level of 35 mg/dL is elevated and consistent with dehydration. Dehydration causes the kidneys to reabsorb more water, leading to higher concentrations of urea in the blood.

C: A BUN level of 10 mg/dL is within the normal range and does not indicate dehydration. This level suggests normal kidney function and hydration status.

D: A BUN level of 31 mg/dL is elevated and suggests dehydration. While not as high as 165 mg/dL, it still indicates that the patient is dehydrated and requires intervention.
