Reading an Exhibit Against the Clock
A simulated four-tab chart frame with a solid tab strip, above it a single horizontal budget bar segmented into blocks labeled STANDARD, EXHIBIT, CASE, CALCULATION and SLACK, the last segment filled.
THE CHART
Tabs: NURSES' NOTES · VITAL SIGNS · LABORATORY · MAR
NURSES' NOTES · 0900. Client admitted yesterday for management of heart failure. Reports that shortness of breath at rest is improved this morning. Ate about half of breakfast. Reports muscle cramping in both calves overnight and says he "feels a bit fluttery." Ambulated to the bathroom with one assist.
VITAL SIGNS · 0900. Temperature 97.9 F. Heart rate 96, irregular. Respirations 18. Blood pressure 106/62. Oxygen saturation 95 percent on room air. Weight down 3 pounds from admission.
LABORATORY · 0600. Serum potassium below the reference interval and lower than yesterday's value. Serum sodium within the reference interval. Serum creatinine unchanged from admission. → BOOK 07 · P5
MAR · due 1000. Furosemide 40 mg by mouth daily. Potassium chloride 20 mEq by mouth daily, held yesterday, dose not given. Metoprolol 25 mg by mouth twice a day.
THE PROMPT. The client's shortness of breath has improved. Which finding should the nurse act on before giving the 1000 medicines, and what does it change?
Tab order
Open the tab named in the question first. Then open the one tab that could change your answer. Two tabs answer most exhibits. Opening all four costs budget without adding information, and it invites you to build a story out of data the question never asked about.
The time budget
Do not memorize a number. Build one. Take the appointment length published in the current bulletin, subtract the tutorial and the breaks you intend to take, and divide by the maximum item count. That quotient is your standard item. Give an exhibit item about double. Give an unfolding case about triple. Give a calculation about double. Hold roughly one minute per hour back as slack for the page 9 interrupt. Verify: appointment length, maximum item count, tutorial, and break rules all come from the current NCSBN candidate bulletin and change.
Calculator discipline
Write the setup on the erasable board before you touch a key. Look at the unit before you look at the digits, because the unit is where the trap lives. Enter every number twice and compare the two results rather than the two entries. Never round in the middle of a calculation; round once, at the end, to whatever precision the item asks for. Formulas and worked math stay with → BOOK 06 · P4.
Margin notethe answer is on the tab you didn't open.
Watch outAn exhibit that seems to have no answer almost always means a tab is still closed. Before you re-read the notes a third time, check which tabs you have actually opened.
Answer key, printed here so it is not in view while you drill: the deciding tabs are LABORATORY and MAR. The falling potassium, the cramping, the irregular rate, and a held potassium dose together mean the furosemide is the drug to question and the potassium replacement is the one to chase.
