Dietary approaches to stop hypertension (DASH) approximately reduces systolic blood pressure by:

# Dietary approaches to stop hypertension (DASH) approximately reduces systolic blood pressure by:

a. 2-4mm Hg

b. 4-9mm Hg

c. 2-8mm Hg

d. 8-14mm Hg

The correct answer is D. 8-14 mm Hg.

Limitation of alcohol consumption will lower by 2-4mm Hg, physical activity will

reduce by 4-9mm Hg and dietary sodium reduction will lower by 2-8mm Hg. Adoption of DASH eating plan will reduce SBP by 8-14 mm Hg.

A patient with mitral valve replacement will require which of the following preoperatively

# A patient with mitral valve replacement  will require which of the following preoperatively?

A. Benzathine Penicillin

B. Tetracycline

C. Procaine penicillin

D. Vibramycin

 

The correct answer is A. Benzathine Penicillin.

Benzathine and procaine penicillins are formulated to delay absorption, resulting in prolonged blood and tissue concentrations. A single intramuscular injection of 1.2 million units of benzathine penicillin maintains serum levels above 0.02 mcg/mL for 10 days, sufficient to treat β-hemolytic streptococcal infection. After 3 weeks, levels still exceed 0.003 mcg/mL, which is enough to prevent β-hemolytic streptococcal infection. A 600,000 unit dose of procaine penicillin yields peak concentrations of 1–2 mcg/mL and clinically useful concentrations for 12–24 hours after a single intramuscular injection.

Petechial hemorrhage is characteristic of which of the following condition

 # Petechial hemorrhage is characteristic of which of the following condition?

A. Agranulocytosis

B. Neutropenia

 C. Pernicious anemia

 D. Thrombocytopenic purpura

The correct answer is D. Thrombocytopenic purpura.

Petechial purpura is minor bleeding into the dermis that is flat and non-blanching. Petechiae are typically found in patients with thrombocytopenia or platelet dysfunction. Palpable purpura occurs in vasculitis. Ecchymosis, or bruising, is more extensive bleeding into deeper layers of the skin. The

lesions are initially dark red or purple but become yellow as haemoglobin is degraded.
