Question 1 of 5
A 5-year-old child is hospitalized for an acute illness. The nurse encourages the family to bring her favorite objects from home. What is the nurse's rationale?
Correct Answer: D
Rationale: Favorite objects from home assist in creating a familiar setting, preventing or minimizing separation anxiety.
Question 2 of 5
Decreased pulmonary blood flow, right-to-left shunting, and deoxygenated blood reaching the systemic circulation are characteristic of:
Correct Answer: A
Rationale: 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 to reach the systemic circulation. 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. 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. 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.
Question 3 of 5
Nursing care for the substance abuse client experiencing alcohol withdrawal delirium includes:
Correct Answer: A
Rationale: These clients are at high risk for seizures during the 1st week after cessation of alcohol intake. Fluid intake should be increased to prevent dehydration. Environmental stimuli should be decreased to prevent precipitation of seizures. Application of restraints may cause the client to increase his or her physical activity and may eventually lead to exhaustion.
Question 4 of 5
After 7 hours in restraints and a total of 30-mg haloperidol in divided doses, a client complains of stiffness in his neck and his tongue 'pulling to one side.' These extrapyramidal symptoms (EPS) will most likely be relieved by the administration of:
Correct Answer: B
Rationale: Benztropine acts to reduce EPS by blocking excess CNS cholinergic activity associated with dopamine deficiency in the basal ganglia by displacing acetylcholine at the receptor site.
Question 5 of 5
Which behaviors are expected to be observed in the 18-month old?
Correct Answer: B, C, E
Rationale: At 18 months, children remove clothes (
B), point to body parts (
C), and kick balls (E). Vocabulary is ~20-50 words (
A), and questioning (
D) emerges later (~2-3 years).
