The nurse reviews the CD4 cell count of a client who is HIV-positive. A result less than which count would indicate to the nurse that the client has AIDS?
1,000 cells/mm3
700 cells/mm3
450 cells/mm3
200 cells/mm3
The Correct Answer is D
A. 1,000 cells/mm3:
A CD4 cell count of 1,000 cells/mm3 is within the normal range for a healthy individual. In HIV-positive individuals, a CD4 count at this level would generally indicate that the immune system is functioning well and has not been significantly compromised by the virus. Therefore, a CD4 count of 1,000 cells/mm3 would not suggest a diagnosis of AIDS.
B. 700 cells/mm3:
Similarly, a CD4 cell count of 700 cells/mm3 is also within the normal range for immune function. While this count may be lower than the typical CD4 count in a healthy individual, it is still considered relatively high and would not indicate immune compromise to the extent seen in AIDS.
C. 450 cells/mm3:
A CD4 cell count of 450 cells/mm3 is also within a range that suggests the immune system is functioning reasonably well. While it may be lower than normal, it is not at a level indicative of severe immune suppression characteristic of AIDS.
D. 200 cells/mm3:
When the CD4 cell count drops below 200 cells/mm3, it indicates significant immune suppression and an increased risk of opportunistic infections. This threshold is used to diagnose AIDS in HIV-positive individuals. At this level, the immune system is severely compromised, leaving the individual vulnerable to various infections and diseases associated with AIDS.

Correct Answer is A
Explanation
A. "I'm sorry you lost your baby."
This response demonstrates empathy and validation of the client's emotions. It acknowledges the client's loss and offers support during a difficult time. By expressing sympathy, the nurse shows understanding and compassion towards the client's grief.
B. "A baby still wasn't formed in your uterus."
This response may come across as dismissive or invalidating of the client's emotions. It does not acknowledge the client's loss or address their emotional needs. It focuses more on the biological aspect of the situation rather than the client's feelings.
C. "Will a pill help your pain?"
This response only addresses physical pain management and does not acknowledge the emotional distress the client is experiencing. While pain relief is important, it is equally important to address the client's emotional needs and provide support during a difficult time.
D. "Why are you crying?"
This response may come across as insensitive or intrusive. It puts the client on the spot and may make them feel uncomfortable or defensive about their emotions. It does not provide empathy or support and fails to acknowledge the client's loss or offer condolences.
Correct Answer is D
Explanation
A. "I should avoid drinking orange juice."
- This statement is incorrect. Vitamin C, found in orange juice and other citrus fruits, can actually enhance the absorption of iron from iron supplements. Therefore, it is recommended to take iron supplements with vitamin C-rich foods or beverages to improve iron absorption. Advising the pregnant woman to avoid orange juice would be counterproductive to optimizing iron absorption.
B. "I should take my iron with milk."
- This statement is incorrect. Calcium, found in milk and dairy products, can inhibit the absorption of iron from iron supplements. Therefore, it is generally advised to avoid taking iron supplements with milk or other calcium-rich foods or beverages. Instead, iron supplements should be taken with water or vitamin C-rich foods or beverages to enhance iron absorption.
C. "I need to eat foods high in fiber."
- While it's important to maintain a balanced diet with adequate fiber intake for overall health, this statement does not directly relate to the appropriate use of iron supplements. While dietary fiber can affect digestion and bowel movements, it does not significantly impact the absorption of iron from iron supplements. Therefore, while it's beneficial to consume a diet high in fiber for various health reasons, it is not specifically necessary in relation to iron supplementation.
D. "I'll call the primary care provider if my stool is black and tarry."
- This statement is correct and indicates successful teaching. Black, tarry stools can indicate the presence of gastrointestinal bleeding, which can occur as a side effect of iron supplementation. By instructing the pregnant woman to contact her primary care provider if she experiences black, tarry stools, she demonstrates understanding of a potential adverse effect of iron supplementation and knows to seek appropriate medical attention if necessary.
