1. At which age does an infant start to recognize familiar faces and objects, such as his or her own hand?
- A. 1 month
- B. 2 months
- C. 3 months
- D. 4 months
Correct answer: C
Rationale: By 3 months, infants begin to recognize familiar faces and objects, such as their own hands. This marks the early stages of visual recognition and cognitive development.
2. Which laboratory value at the time of diagnosis should the nurse anticipate would determine the worst prognosis for a child with leukemia?
- A. Slow response to chemotherapy
- B. Platelets of 150,000/mcL
- C. Leukocytes less than 10,000/mcL
- D. Leukocytes of 275,000/mcL
Correct answer: D
Rationale: A high white blood cell count (leukocytes of 275,000/mcL) at diagnosis is associated with a worse prognosis in leukemia because it indicates a more aggressive disease with a higher tumor burden. Slow response to chemotherapy (choice A) is a consequence of the aggressive disease and not a determining factor at diagnosis. Platelets of 150,000/mcL (choice B) and leukocytes less than 10,000/mcL (choice C) are within normal ranges and not indicative of a worse prognosis in leukemia.
3. The parent of an infant with colic tells the nurse, "All this baby does is scream at me; it is a constant worry." What is the nurse's best action?
- A. Encourage the parent to verbalize feelings.
- B. Encourage the parent not to worry so much.
- C. Assess the parent for other signs of inadequate parenting.
- D. Reassure the parent that colic rarely lasts past age 9 months.
Correct answer: A
Rationale: Encouraging the parent to express their feelings is crucial in providing support and addressing the emotional challenges that colic can present. Reassuring the parent about the temporary nature of colic can also be helpful.
4. Clinical manifestations of sodium excess (hypernatremia) include which signs or symptoms?
- A. Hyperreflexia
- B. Abdominal cramps
- C. Cardiac dysrhythmias
- D. Dry, sticky mucous membranes
Correct answer: D
Rationale: Hypernatremia often presents with dry, sticky mucous membranes due to dehydration. Hyperreflexia and abdominal cramps may also occur, but dry mucous membranes are more consistently observed in cases of sodium excess.
5. During the 2-month well-child checkup, the nurse expects the infant to respond to sound in which manner?
- A. Respond to name
- B. React to loud noise with Moro reflex
- C. Turn his or her head to side when sound is at ear level
- D. Locate sound by turning his or her head in a curving arc
Correct answer: B
Rationale: At 2 months, infants typically react to loud noises with the Moro reflex, a startle response that is normal at this stage of development.
