Question 1 of 5
A patient taking Digoxin is experiencing severe bradycardia, nausea, and vomiting. A lab draw shows that their Digoxin level is 4 ng/mL. What medication do you anticipate the physician to order for this patient?
Correct Answer: C
Rationale: Digoxin toxicity (level >2 ng/mL) causes bradycardia and GI symptoms; Digibind (C) is the antidote to reverse toxicity.
Question 2 of 5
After the nurse teaches the patient with stage 1 hypertension about diet modifications that should be implemented, which diet choice indicates that the teaching has been effective?
Correct Answer: D
Rationale: For the prevention of hypertension, the Dietary Approaches to Stop Hypertension(DASH) recommendations include increasing the intake of calcium-rich foods. Caffeine restriction and decreased protein intake are not included in the recommendations. Nuts are high in beneficial nutrients and 4 to 5 servings weekly are recommended in the DASH diet.
Question 3 of 5
The staff educator is teaching ED nurses about hypertensive crisis. The nurse educator should explain that hypertensive urgency differs from hypertensive emergency in what way?
Correct Answer: D
Rationale: Hypertensive emergencies are acute, life-threatening BP elevations that require prompt treatment in an intensive care setting because of the serious target organ damage that may occur. Blood pressures are extremely elevated in both urgency and emergencies, but there is no evidence of target organ damage in hypertensive urgency. Extremely close hemodynamic monitoring of the patient's BP is required in both situations. The medications of choice in hypertensive emergencies are those with an immediate effect, such as IV vasodilators. Oral doses of fast-acting agents, such as beta-adrenergic blocking agents, angiotensin-converting enzyme inhibitors, or alpha-agonists, are recommended for the treatment of hypertensive urgencies.
Question 4 of 5
A patient comes to the walk-in clinic complaining of frequent headaches. While assessing the patient's vital signs, the nurse notes the BP is 161/101 mm Hg. According to JNC 7, how would this patient's BP be defined if a similar reading were obtained at a subsequent office visit?
Correct Answer: D
Rationale: JNC 7 defines stage 2 hypertension as a reading 160/100 mm Hg.
Question 5 of 5
Regarding cerebrospinal fluid:
Correct Answer: D
Rationale: CSF contains very low levels of cholesterol relative to plasma due to the blood-brain barrier's selective permeability.
