A nurse is preparing to administer vancomycin 500 mg PO daily divided into four equal doses. The amount available is vancomycin 125 mg capsules. How many capsules should the nurse administerwitheachdose?
The Correct Answer is ["1"]
If the nurse needs to administer vancomycin 500 mg PO daily divided into four equal doses, and the available capsules are vancomycin 125 mg each, the nurse would administer:
500 mg total daily dose ÷ 4 doses = 125 mg per dose
Since each capsule contains 125 mg of vancomycin, the nurse would administer 1 capsule with each dose.

Correct Answer is C
Explanation
A. "Yes. Hypertension is prevalent among men; it is fortunate we caught this during your routine examination.": This response is premature as it assumes a diagnosis of hypertension based on a single elevated blood pressure reading without further assessment or confirmation.
B. "We will need to reevaluate your blood pressure because age places you at high risk for hypertension.": While age is a risk factor for hypertension, it is important not to jump to conclusions based on one blood pressure reading. Reevaluation and monitoring are necessary before making any definitive diagnoses or treatment decisions.
C. "A single elevated blood pressure does not confirm hypertension. You will need to have your blood pressure reassessed several times before a diagnosis can be made.": This response is appropriate because it acknowledges the need for further assessment and monitoring before determining if the client has hypertension. It also educates the client about the importance of multiple readings for an accurate diagnosis.
D. "You have no need to worry. Your pressure is probably elevated because you are being tested.": This response dismisses the client's concerns and does not provide accurate information about blood pressure assessment and hypertension diagnosis.
Correct Answer is D
Explanation
A. Sinus bradycardia: Sinus bradycardia is characterized by a regular rhythm with a heart rate less than 60 beats per minute. In this case, the heart rate is 64 beats per minute, which falls within the normal range, not consistent with sinus bradycardia.
B. Sinus arrhythmia: Sinus arrhythmia typically presents as a variation in the R-R interval with respiration, often seen as an irregularity in the heart rate. The provided characteristics describe a regular rhythm, so sinus arrhythmia is not the correct interpretation.
C. Sinus tachycardia: Sinus tachycardia is characterized by a regular rhythm with a heart rate greater than 100 beats per minute. The heart rate in this case is 64 beats per minute, which is not indicative of sinus tachycardia.
D. Normal sinus rhythm: Normal sinus rhythm refers to a regular rhythm with a heart rate between 60 and 100 beats per minute, P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and normal QRS complex duration (less than 0.12 seconds). The provided characteristics, including regular P waves, regular QRS complexes, a PR interval of 0.16 seconds, and a heart rate of 64 beats per minute, align with a normal sinus rhythm interpretation.
