The nurse teaches a pregnant woman about the presumptive, probable, and positive signs of pregnancy.
The woman demonstrates understanding of the nurse's instructions if she states that a positive sign of pregnancy is:.

Choice A rationale:

Ask her to turn to one side. The supine position during labor can compress the vena cava, reducing blood flow to the uterus and potentially compromising fetal oxygenation. Turning the woman to her side, especially the left side, can relieve this pressure and improve blood flow to the uterus, ensuring adequate oxygen supply to the fetus. This position change is crucial for the well-being of both the mother and the baby during labor.

Choice B rationale:

Elevate her feet and legs. Elevating the woman's feet and legs might not be effective in relieving the pressure on the vena cava, as it does not change the orientation of the uterus in relation to the vena cava. Turning the woman to her side is a more appropriate and effective action to improve blood flow to the uterus and fetus.

Choice C rationale:

Take her blood pressure. While monitoring the woman's blood pressure is essential during labor, it is not the most appropriate action in this situation. The priority is to relieve the compression of the vena cava by changing the woman's position.

Choice D rationale:

Determine whether fetal tachycardia is present. Monitoring the fetal heart rate is crucial during labor, but the woman's position should be the immediate concern if she is lying in the supine position. Changing her position to relieve the vena cava compression takes precedence to ensure adequate oxygenation to the fetus.

Choice A rationale:

Some form of cancer. Rationale: Tender, enlarged, and warm cervical lymph nodes are indicative of infection or inflammation close to the site. Cancerous lymph nodes are usually painless and firm. In this case, the symptoms suggest an active immune response to infection or inflammation in proximity to the palpated lymph nodes.

Choice B rationale:

Local scalp infection common in children. Rationale: Local scalp infection, while possible, typically does not cause tender, enlarged, and warm cervical lymph nodes. These symptoms are more consistent with an active immune response to infection or inflammation in the area near the lymph nodes.

Choice C rationale:

Infection or inflammation distal to the site. Rationale: Symptoms such as tenderness, enlargement, and warmth in cervical lymph nodes indicate a local response to infection or inflammation close to the site. "Distal" refers to a location away from the affected area, making this choice inappropriate for the described symptoms.

Choice D rationale:

Infection or inflammation close to the site. Rationale: Tender, enlarged, and warm cervical lymph nodes suggest an active immune response to infection or inflammation in the vicinity. These symptoms are signs of localized inflammation and are commonly seen in conditions such as tonsillitis, pharyngitis, or other upper respiratory infections.
