Extract:
Question 1 of 5
Based on the client's clinical presentation, which drug should the nurse anticipate will be administered intravenously?
Correct Answer: A
Rationale: Heparin is the standard anticoagulant used to prevent further clot formation in pulmonary embolism.
Question 2 of 5
When the nurse is teaching a client to self-administer nose drops, which head position is appropriate?
Correct Answer: C
Rationale: Tilting the head backward allows nose drops to reach the nasal passages effectively by gravity, ensuring proper distribution of the medication.
Question 3 of 5
The nurse is assessing the client diagnosed with COPD. Which data require immediate intervention by the nurse?
Correct Answer: B
Rationale: High oxygen (8 LPM,
B) risks CO2 retention in COPD, requiring immediate adjustment (2–4 LPM). Sputum (
A), accessory muscles (
C), and barrel chest (
D) are expected but less urgent.
Question 4 of 5
Which is the correct volume needed for the nurse to administer the prescribed dose of 0.1 mg of epinephrine to the client?
Correct Answer: B
Rationale: For a 1:1,000 epinephrine solution (1 mg/mL), a 0.1 mg dose equals 0.1 mL, calculated as 0.1 mg ÷ 1 mg/mL = 0.1 mL.
Question 5 of 5
The nurse is preparing to administer warfarin (Coumadin), an oral anticoagulant, to a client diagnosed with a pulmonary embolus. Which data would cause the nurse to question administering the medication?
Correct Answer: B
Rationale: An INR of 5 (
B) is above the therapeutic range (2–3 for pulmonary embolus), indicating excessive anticoagulation and bleeding risk, so warfarin should be questioned. PTT (
A) is for heparin, not warfarin. PT (
C) alone is not standardized. ESR (
D) is irrelevant to anticoagulation.
