1. How can light therapy be effective?

A. overcoming weight problems.
B. helping with allergies.
C. use in alternative medical treatments.
D. working with sleep patterns.

Correct answer: D

Rationale: Light therapy can be effective in treating problems associated with sleep patterns, stress, moods, jaundice in newborns, and seasonal affective disorders. While light therapy is not typically used for overcoming weight problems or helping with allergies, it is specifically known for its benefits in regulating sleep patterns. Therefore, the correct answer is 'working with sleep patterns.' Choices A, B, and C are incorrect as light therapy is not commonly utilized for overcoming weight problems, helping with allergies, or as a general alternative medical treatment.

2. Which of the following is not a primary function of the kidneys?

A. blood pressure control
B. vitamin D activation
C. erythropoietin production
D. reabsorption of waste products

Correct answer: D

Rationale: The correct answer is reabsorption of waste products because the kidneys excrete waste products rather than reabsorbing them. Choices A, B, and C are indeed primary functions of the kidneys. The kidneys play a crucial role in regulating blood pressure, activating vitamin D, and producing erythropoietin, which stimulates red blood cell production. Therefore, the primary role of the kidneys is to filter blood, remove waste products, regulate fluid balance, and maintain electrolyte balance.

3. A patient has been diagnosed with fibromyalgia and COPD. Which of the following tasks should the nurse delegate to a nursing assistant?

A. Transferring the patient to the shower.
B. Ambulating the patient for the first time.
C. Taking the patient's breath sounds.
D. Educating the patient on monitoring fatigue.

Correct answer: A

Rationale: The correct answer is to delegate the task of transferring the patient to the shower to a nursing assistant. Nursing assistants are trained to assist with transfers safely, making this task appropriate for delegation. Ambulating the patient for the first time involves assessing the patient's mobility and tolerance, which requires more assessment and monitoring by a nurse, especially in a patient with fibromyalgia and COPD. Taking the patient's breath sounds involves assessing the patient's respiratory status, which is a nursing responsibility due to the need for clinical judgment. Educating the patient on monitoring fatigue involves providing vital information and should be done by the nurse to ensure comprehensive understanding and tailored recommendations.

4. Which task would be appropriate for the LPN to perform?

A. Changing a colostomy bag.
B. Hanging a new bag of TPN.
C. Drawing a peak antibiotic blood level from a central line.
D. Administering IV pain medication to a two-day post-op client.

Correct answer: A

Rationale: The correct answer is changing a colostomy bag. This task falls within the LPN's scope of practice. LPNs are trained to provide basic nursing care, including assisting with activities of daily living and certain medical procedures like changing ostomy bags. Hanging a new bag of TPN and drawing a peak antibiotic blood level from a central line are tasks that require a higher level of training and are typically performed by RNs due to their complexity and potential risks. Administering IV pain medication to a two-day post-op client is usually the responsibility of an RN as it involves close monitoring, assessment of the client's condition, and the administration of potent medications that require a higher level of clinical judgment and expertise.

5. Which of the following infant behaviors demonstrates the concept of object permanence?

A. The infant cries when his mother leaves the room.
B. The infant looks at the floor to find a toy that he was playing with and dropped.
C. The infant picks up another toy after the one he was playing with rolls under the couch.
D. The infant participates in a game of patty-cake.

Correct answer: B

Rationale: Object permanence occurs when the infant learns that something or someone still exists even though they might not be able to see it or them. This typically develops between 9 and 10 months of age. The correct answer, 'The infant looks at the floor to find a toy that he was playing with and dropped,' demonstrates object permanence as the infant understands that the toy still exists even though it is temporarily out of sight. Choices A and C do not directly relate to object permanence as the behaviors described do not necessarily indicate an understanding of objects existing when out of sight. Choice D is incorrect as participating in a game of patty-cake does not involve demonstrating object permanence. Peek-a-boo is a more suitable example of a game that demonstrates object permanence, as the infant continues to look for the hidden face, understanding that it still exists even though temporarily unseen.
