Explanation:
(A) A priority nursing goal is attending to the client's safety and well-being. Reorient frequently, remove dangerous objects, and maintain consistent environment. (B) Short, frequent visits are recommended to avoid overstimulation and fatigue. (C) Short, concise, simple explanations are easier to understand. (D) Mental capability and attention span deficits make learning difficult and frustrating.

Section: Questions Set D
Explanation:
(A) Tetralogy of Fallot is the most common cyanotic heart defect, which includes a VSD, pulmonary stenosis, an overriding aorta, and ventricular hypertrophy. The blood flow is obstructed because the pulmonary stenosis decreases the pulmonary blood flow and shunts blood through the VSD, creating a right-to-left shunt that allows deoxygenated blood the reach the systemic circulation. (B) A VSD alone creates a left-to-right shunt.
The pressure in the left ventricle is greater than that of the right; therefore, the blood will shunt from the left ventricle to the right ventricle, increasing the blood flow to the lungs. No deoxygenated blood will reach the systemic circulation. (C) In patent ductus arteriosus, the pressure in the aorta is greater than in the pulmonary artery, creating a left-to-right shunt. Oxygenated blood from the aorta flows into the unoxygenated blood of the pulmonary artery. (D) Transposition of the great arteries results in two separate and parallel circulatory systems. The only mixing or shunting of blood is based on the presence of associated lesions.

Section: Questions Set E
Explanation:
(A, C, D) These answers are incorrect. (B) Normal fluid requirement for this pediatric client is based on the fact that 0-10 kg of weight equals 100 mL/kg per day. This infant weighs 15 pounds (6.8 kg). Thus, 100 mL X 6.8
680 mL/day.

Explanation:
(A) A common side effect of gentamicin is nephrotoxicity. The serum laboratory test that best reflects kidney function is serum creatinine. (B) Serum sodium has no relationship to gentamicin. (C) Serum calcium has no relationship to gentamicin. (D) Serum potassium has no relationship to gentamicin. If a client has impaired renal function secondary to gentamicin administration, he or she may also have hyperkalemia as a secondary disorder.

Explanation
(A) The client should be encouraged to attend the unit activities. The nurse and client should choose a few activities for the client to attend that will be positive experiences for him. (B) The nurse should encourage the client to discuss his feelings and to begin to deal with the depression. (C) Depressed persons often have little appetite and poor fluid intake. Constipation is common. (D) A calm, consistent level of stimuli is most effective. Sensory deprivation and overstimulation should be avoided.
