Nurses’ Notes
1100:
• Admitted to the medical unit. He is pale with a capillary refill of 5 seconds. Is sleepy but responds to commands. An 18-gauge peripheral IV line started in the right hand, flushes easily with no redness or edema. Bolus of IV fluids given.
1115:
• Healthcare provider notified of arterial blood gas values. Sodium bicarbonate given as prescribed.
1200:
• Capillary refill 2 seconds

Patient Data.
Question 2 of 5
Review H and P, nurses notes, laboratory results, flow sheet, and orders. Click to mark whether the assessment finding represents a therapeutic result of the sodium bicarbonate administered, a non-therapeutic side-effect, or an unrelated finding.
| Options | therapeutic result | non-therapeutic side-effect | unrelated finding |
|---|---|---|---|
| Capillary refill 2 seconds | |||
| Blood pressure 113/72 mm Hg | |||
| Bicarbonate 22 mEq/L (22 mmol/L) | |||
| Sodium 152 mEq/L (152 mmol/L) | |||
| 400 mL urine output | |||
| Heart rate 77 beats/minute |
Correct Answer:
Rationale: A: therapeutic result B: therapeutic result C: therapeutic result D: non-therapeutic side-effect E: unrelated finding F: therapeutic result Sodium bicarbonate corrects metabolic acidosis (
C) and improves perfusion (A, B, F). Hypernatremia (
D) is a side effect, and urine output (E) is unrelated to bicarbonate.

Question 3 of 5
A client who is taking dextroamphetamine-amphetamine extended-release tablets for attention deficit hyperactivity disorder (ADHD) reports having difficulty sleeping at night. Which assessment is most important for the nurse to obtain? Which assessment is most important for the nurse to obtain?
Correct Answer: B
Rationale: Dextroamphetamine-amphetamine is a stimulant that can cause insomnia if taken too late. Assessing dose timing is critical to adjust administration and mitigate sleep issues.
Question 4 of 5
The nurse is teaching a client how to use an inhaler device. Which client statement indicates to the nurse that the client understands the instructions? Which client statement indicates to the nurse that the client understands the instructions?
Correct Answer: A
Rationale: Rinsing the mouth after inhaler use, especially with corticosteroids, prevents oral thrush and irritation, indicating proper understanding.
Question 5 of 5
A client with chemotherapy-induced nausea receives a prescription for metoclopramide. Which adverse effect is most important for the nurse to report? Which adverse effect is most important for the nurse to report?
Correct Answer: D
Rationale: Involuntary movements, such as tardive dyskinesia, are a serious, potentially irreversible side effect of metoclopramide. This requires immediate reporting to the provider for possible discontinuation and evaluation.
