A newborn girl's father expresses concern that the newborn does not have good control of her hands and arms. It is important for the father to realize certain neurological patterns that characterize the newborn:
- A. Mild hypotonia is expected in the upper extremities.
- B. Purposeless, uncoordinated movements of the arms are indicative of neurological dysfunction.
- C. Function progresses in a head-to-toe, proximal-distal fashion.
- D. Asymmetrical movement of the extremities is not unusual and will disappear with maturation of the central nervous system.
Correct Answer: C
Rationale: Term neonates are predominantly in a flexed position with strong active muscle tone that increases. Newborns are slightly hypertonic. Neonatal movements may be jerky and uncoordinated as the neonate works against gravity in contrast to the buoyancy of the amniotic fluid. Jerky movements must be differentiated from the tremors of hypoglycemia, hypocalcemia, and neurological dysfunction. Growth of the newborn progresses in a cephalocaudal, proximal-distal fashion. Knowledge regarding infant development may facilitate parental involvement and infant stimulation. Asymmetrical movements of the extremities are indicative of neurological dysfunction.

The nurse is caring for a client with a history of Addison’s disease. The nurse should expect the client to have:
- A. Hypotension
- B. Hypertension
- C. Hyperglycemia
- D. Weight gain

In teaching the client about proper umbilical cord care, the nurse recommends that:
- A. Petrolatum be placed around the cord after the sponge bath
- B. A belly binder be applied to prevent umbilical hernia
- C. The area be cleansed at diaper changes with alcohol and inspected for redness or drainage
- D. The cord clamp be left on until the cord stump separates
Correct Answer: C
Rationale: Petrolatum does not allow the cord to dry and will encourage infection. Belly binders do not facilitate drying of the cord and will encourage abdominal relaxation. Frequent applications of alcohol will facilitate drying and discourage infection. The cord clamp can be removed in 24 hours. Leaving it on is cumbersome and could pull on the cord unnecessarily.
A client admitted to the psychiatric unit claims to be the Pope and insists that he will not be kept away from his followers. The most likely explanation for the client's delusion is:
- A. A reaction formation
- B. A stressful event
- C. Low self-esteem
- D. Overwhelming anxiety
Correct Answer: C
Rationale: Delusions of grandeur, like claiming to be the Pope, often stem from low self-esteem in psychiatric disorders like schizophrenia, compensating for feelings of inadequacy. The other factors are less specific.
The physician has ordered DDAVP (desmopressin acetate) for a client with diabetes insipidus. Which finding indicates that the medication is having its intended effect?
- A. The client's appetite has improved.
- B. The client's morning blood sugar was 120 mg/dL.
- C. The client's urinary output has decreased.
- D. The client's activity level has increased.
Correct Answer: C
Rationale: DDAVP reduces excessive urination in diabetes insipidus by mimicking antidiuretic hormone, decreasing urinary output. Appetite, blood sugar, and activity are not directly affected.
