Question 1 of 5
Loss of appetite for a child with leukemia is a major recurrent problem. The plan of care should be designed to:
Correct Answer: A
Rationale: Ignoring refusals to eat and rewarding eating attempts are the most successful means of increasing intake. This goal is not specific enough or related to the loss of appetite. This goal is not possible at this time based on his illness. This goal is helpful, but alone will not address his loss of appetite.
Question 2 of 5
A 20-year-old client presents to the obstetrics-gynecology clinic for the first time. She tells the nurse that she is pregnant and wants to start prenatal care. After collecting some initial assessment data, the nurse measures her fundal height to be at the level of the umbilicus. The nurse estimates the fetal gestational age to be approximately:
Correct Answer: C
Rationale: At 10 weeks, the fundus is located slightly above the symphysis pubis. At 16 weeks, the fundus is halfway between the symphysis pubis and the umbilicus. At 20 weeks, the fundus is located approximately at the umbilicus. At 30 weeks, the fundal height is about 30 cm, or 10 cm above the umbilicus.
Question 3 of 5
Children often experience visual impairments. Refractive errors affect the child's visual activity. The main refractive error seen in children is myopia. The nurse explains to the child's parents that myopia may also be described as:
Correct Answer: C
Rationale: Cataracts are not considered refractive errors. Cataracts can be described as opacity of the lens. Hyperopia is the term for farsightedness. One can see objects at a distance more clearly than close objects. Myopia is the term for nearsightedness. Objects that are close in distance are more clearly seen. Lazy eye refers to strabismus or misalignment of the eyes.
Question 4 of 5
Which classification of drugs is contraindicated for the client with hypertrophic cardiomyopathy?
Correct Answer: A
Rationale: Positive inotropic agents should not be administered owing to their action of increasing myocardial contractility. Increased ventricular contractility would increase outflow tract obstruction in the client with hypertrophic cardiomyopathy. Vasodilators are not typically prescribed but are not contraindicated. Diuretics are used with caution to avoid causing hypovolemia. Antidysrhythmics are typically needed to treat both atrial and ventricular dysrhythmias.
Question 5 of 5
A client returns to the cardiovascular intensive care unit following his coronary artery bypass graft. In planning his care, the most important electrolyte the nurse needs to monitor will be:
Correct Answer: C
Rationale: Potassium will need to be closely monitored because of its effects on the heart. Hypokalemia could result in supraventricular tachyarrhythmias.
