A patient’s blood pressure is 90/72 mm Hg. What is the patient’s pulse pressure?

40 mm Hg.

25 mm Hg.

18 mm Hg.

12 mm Hg.

Answer and Explanation

The Correct Answer is C

Choice A reason: Pulse pressure is calculated as systolic (90) minus diastolic (72), equaling 18 mm Hg, not 40. This is incorrect, as it overestimates the pulse pressure, unlike the nurse’s accurate calculation based on the patient’s blood pressure readings.

Choice B reason: A pulse pressure of 25 mm Hg doesn’t match the calculation of 90 minus 72, which is 18 mm Hg. This is incorrect, as it’s inaccurate compared to the nurse’s correct determination of the patient’s pulse pressure from the given values.

Choice C reason: Pulse pressure is systolic (90 mm Hg) minus diastolic (72 mm Hg), equaling 18 mm Hg. This aligns with cardiovascular assessment, making it the correct value the nurse would calculate for the patient’s blood pressure of 90/72 mm Hg.

Choice D reason: A pulse pressure of 12 mm Hg is incorrect, as 90 minus 72 equals 18 mm Hg. This underestimates the value, making it incorrect compared to the nurse’s accurate calculation of the patient’s pulse pressure based on the blood pressure.

Correct Answer is A

Explanation

Choice A reason: Limiting dietary fiber is incorrect for IBS, as soluble fiber helps regulate bowel movements. This indicates a need for further teaching, making it the correct statement, as it contradicts the nurse’s instructions to include fiber for IBS symptom management.

Choice B reason: Drinking 8 to 10 cups of fluid daily supports hydration and bowel function in IBS, showing understanding. This is incorrect, as it aligns with the nurse’s teaching, unlike the fiber limitation statement requiring further client education.

Choice C reason: Eating regular meals and chewing well stabilizes digestion in IBS, reflecting correct understanding. This is incorrect, as it aligns with the nurse’s instructions, unlike the fiber limitation statement that indicates a need for further teaching.

Choice D reason: Taking prescribed medications to regulate bowel patterns is appropriate for IBS management, showing understanding. This is incorrect, as it aligns with the nurse’s teaching, unlike the incorrect fiber limitation statement needing further client instruction.

A. A 45-year-old with a nasogastric (NG) tube who has dry oral mucosa and reports feeling very thirsty. B. A 57-year-old receiving IV diuretics whose blood pressure is 88/52 mm Hg. C. A 67-year-old with nausea and vomiting who reports abdominal cramps. D. A 77-year-old with normal saline infusing at 150 mL/hr with an average hourly urine output.

Correct Answer is B

Explanation

Choice A reason: Dry mucosa and thirst suggest dehydration, but hypotension (88/52) is more life-threatening. Low blood pressure requires immediate assessment, making this incorrect, as it’s less urgent than the nurse’s priority to address the client with critical hemodynamic instability.

Choice B reason: A blood pressure of 88/52 mm Hg in a client on IV diuretics indicates severe hypotension, a life-threatening condition requiring immediate assessment. This aligns with prioritization in acute care, making it the correct client for the nurse to assess first post-shift report.

Choice C reason: Nausea, vomiting, and cramps are concerning but less urgent than hypotension (88/52), which risks organ perfusion. Low blood pressure is critical, making this incorrect, as it’s secondary to the nurse’s priority of assessing the client with unstable vitals.

Choice D reason: Normal saline at 150 mL/hr with adequate urine output is stable. Hypotension (88/52) is more critical, making this incorrect, as it’s a lower priority compared to the nurse’s need to assess the client with life-threatening low blood pressure first.
