The registered nurse(RN) is caring for a patient with a hypertensive crisis who is receiving sodium nitroprusside. Which nursing action can the nurse delegate to an experienced licensed practical/vocational nurse (LPN/VN)?

Correct Answer: D

Rationale: LPN/VN education and scope of practice include the correct use of common equipment such as automatic noninvasive blood pressure machines. Assessment, evaluation, and medication titration require advanced nursing judgment and education, and should be done by RNs.

Correct Answer: C

Rationale: Hypertension is confirmed by two or more readings with systolic pressure of at least 140 mm Hg and diastolic pressure of at least 90 mm Hg. An age of 56 does not constitute a risk factor in and of itself. The nurse should not tell the student that there is no need to worry.

Correct Answer: B

Rationale: To prevent or delay progression to hypertension and reduce risk, JNC 7 urged health care providers to encourage people with blood pressures in the prehypertension category to begin lifestyle modifications, such as nutritional changes and exercise. There is no need for patients to limit their activity in the morning or to avoid potassium and protein intake.

Correct Answer: C

Rationale: Sodium (Na+) concentration is nearly equal in CSF and plasma.

Correct Answer: D

Rationale: Sounds of Korotkoff occur when turbulent flow develops as the cuff pressure decreases.
