The nurse knows which congenital cardiac defect is characterized by a mixing of well-oxygenated blood with poorly oxygenated blood.

Hypoplastic heart syndrome

Atrioventricular canal defect

Tetralogy of Fallot

Coarctation of the aorta

Answer and Explanation

The Correct Answer is B

A. Hypoplastic heart syndrome: Characterized by underdevelopment of the left side of the heart, not mixing of blood.
B. Atrioventricular canal defect: An atrioventricular canal defect allows oxygenated and deoxygenated blood to mix due to the presence of a common atrioventricular valve and defects in the atrial and ventricular septa. This defect results in a mixture of oxygenated and deoxygenated blood, which can cause varying levels of oxygenation in the blood delivered to the body.
C. Tetralogy of Fallot: Involves a ventricular septal defect leading to right-to-left shunting, but not a direct mixing of oxygenated and deoxygenated blood.
D. Coarctation of the aorta: Involves narrowing of the aorta, not mixing of oxygenated and deoxygenated blood.

Correct Answer is ["0.3"]

Explanation

Convert weight from pounds to kilograms:

19pounds÷2.2=8.64kg

Calculate the total daily dose:

0.07mg/kg/day×8.64kg=0.6048mg/day

Divide the daily dose into two doses:

0.6048mg/day÷2=0.3024mg/dose

Round off the dose to two decimal places:

0.3024mg≈0.30mg

The maximum amount of medication per dose is 0.3 mg.

A. slight yellow vaginal discharge B. Decrease in urinary frequency C. frothy, white vaginal discharge D. low grade fever for three (3) days

Correct Answer is A

Explanation

A. slight yellow vaginal discharge: Gonorrhea often presents with a purulent or yellowish vaginal discharge in females. It is one of the common symptoms along with pelvic pain and dysuria.
B. Decrease in urinary frequency: Gonorrhea can actually increase urinary frequency or cause dysuria. A decrease in frequency is not typical for gonorrhea.
C. frothy, white vaginal discharge: This is more characteristic of Trichomoniasis, not gonorrhea. Gonorrhea usually presents with a thicker, more purulent discharge.
D. low grade fever for three (3) days: While fever can be associated with many infections, it is not a common primary symptom of gonorrhea in the absence of more specific symptoms like discharge or pelvic pain.
