nswer: b. Encouraging the client to use the call bell for assistance. Explanation: Encouraging the client to use the call bell for assistance is the most important intervention for fall prevention. It promotes the client's involvement in their own safety and ensures that help is readily available when needed.

Incorrect choices: a. Placing a sign on the client's room door indicating fall risk is a helpful visual reminder, but it does not actively prevent falls. c. Providing a nonskid mat on the floor beside the client's bed can reduce the risk of slipping but does not address other factors that contribute to falls. d. Ensuring the client has adequate lighting in the room is important for preventing falls, but it is not the most critical intervention. The client's ability to seek assistance when needed is more crucial.

Choice A rationale: Identification of a fetal heartbeat via Doppler or ultrasound is a positive sign because it provides objective, undeniable evidence of a living fetus separate from the maternal systems.

Choice B rationale: Palpation of the fetal outline is considered a probable sign of pregnancy. While suggestive, it is not definitive because uterine tumors or myomas can occasionally mimic the fetal shape.

Choice C rationale: Visualization of the fetus through ultrasound or radiographic study is a positive sign. It offers direct, objective confirmation of the embryo or fetus, leaving no room for diagnostic error.

Choice D rationale: Verification of fetal movement by a trained healthcare provider is a positive sign. Unlike subjective maternal "quickening," professional palpation of movement confirms the presence of a live, developing fetus.

Choice E rationale: A positive hCG test is a probable sign of pregnancy. Human chorionic gonadotropin levels can be elevated by certain medications, molar pregnancies, or specific types of choriocarcinoma tumors.
