A 3monthold infant, born at 38 weeks of gestation,

Question 1 of 5

A 3-month-old infant, born at 38 weeks of gestation, will hold a rattle if it is put in her hands, but she will not voluntarily grasp it. How should the nurse interpret this action?

A. Normal development B. Significant developmental lag C. Slightly delayed development due to prematurity D. Suggestive of a neurologic disorder such as cerebral palsy

Correct Answer: C

Rationale: At 3 months of age, most infants should be able to voluntarily grasp objects placed in their hands. This infant, who was born at 38 weeks of gestation, is showing signs of slight delay in development. Premature infants often have developmental delays, especially in motor skills, compared to full-term infants. The fact that the infant can hold a rattle if it is put in her hands is a positive sign, indicating that she is on the right track developmentally but might be a little behind schedule. Continuing to monitor the infant's progress and providing appropriate developmental stimulation can help promote further motor skill development. There is no indication at this point to suspect a significant developmental lag or a neurologic disorder like cerebral palsy without further assessment and observation.

Question 4 of 5

Which explanation regarding cardiac catheterization is appropriate for a preschool child?

A. Postural drainage will be performed every 4 to 6 hours after the test. B. It is necessary to be completely "asleep" during the test. C. The test is short, usually taking less than 1 hour. D. When the procedure is done, you will have to keep your leg straight for at least 4 hours.

Correct Answer: C

Rationale: For a preschool child, the appropriate explanation about cardiac catheterization would be that the test is short, usually taking less than 1 hour. This explanation is suitable for a preschool child because it provides a simple and clear understanding of what to expect during the procedure. Preschool-aged children have limited attention spans and may become anxious about medical procedures, so providing a concise and reassuring explanation can help alleviate their fears. Additionally, knowing that the test will not take a long time can help the child feel more at ease about the procedure.

Question 5 of 5

The nurse is teaching a group of women to perform breast self-examination. The nurse should explain that the purpose of performing the examination is to discover:

A. Cancerous lumps. B. Changes from previous self-examinations. C. Areas of thickness or fullness. D. Fibrocystic masses.

Correct Answer: A

Rationale: The primary purpose of performing breast self-examination is to detect any abnormal changes in the breast tissue, including the presence of cancerous lumps. By regularly examining their breasts, women can become familiar with the normal look and feel of their breasts, making it easier to identify any new lumps or other changes that may indicate a potential problem, such as breast cancer. Detecting cancerous lumps early through self-examination can lead to early detection and improved treatment outcomes. It is important for women to perform breast self-examinations regularly and report any concerning findings to their healthcare provider for further evaluation.
